$ The Canadian Association of Physicists, in cooperation with the Chemical Institute of Canada and the Science Council of Canada, is sponsoring a mail survey of selected Canadian science graduates. A questionnaire is now being mailed to all those who received a bachelor's degree with honours in physics or chemistry (or a combination of one of these fields with another subject area) from a Canadian university in 1954, 1959 and 1964. The survey is the key component of a study of Canadian science education and science manpower. Cooperation of all respondents in filling out the form is most essential to the success of the work. An answer is desired whether the respondent is in or out of his field of undergraduate specialization. The completed study should be of use to all those who are interested in the career patterns and utilization of science graduates. Copies of the completed work will be on file at the sponsoring organizations; results will probably appear both in this journal and in report form in 1971. A summary will be sent to all who cooperate in the project. All answers will be kept confidential and only statistical summaries will be shown. The emphasis throughout will be on comparison of the three graduating classes. The Canadian Association of Physicists sincerely hopes that all those receiving a survey form will respond quickly and co-operate in this highly important project.

ENSEIGNEMENT COLLÉGIAL

CHIMIE DEUXIÈME ÉDITION

par Bruce H. MAHAN de l'Université de Californie, Berkeley

Texte français :

Philibert L'ÉCUYER et Marcel LEFRANÇOIS de l'Université Laval.

Il y a loin de l'atomisme des Grecs à l'actuelle théorie atomique de la matière développée par des chercheurs prestigieux comme Rutherford, Planck, Bahr, Einstein.

S'appuyant sur cette théorie atomique et s'y référant sans cesse, le présent manuel de chimie générale est néanmoins accessible aux étudiants sérieux en sciences, qui possèdent déjà les connais-sances de base en chimie, les préparant aux cours plus approfondis et spécialisés.

Au lieu de commencer par une description détail-lée de la structure électronique des atomes, comme c'est généralement l'habitude de faire, l'auteur con-sacre neuf chapitres à un approfondissement des principes élémentaires de la chimie, dans le but de permettre aux étudiants de faire leur laboratoire de chimie quantitative aussitôt que possible. Les propriétés macroscopiques de la matière, la stoechio-métrie, les réactions et les systèmes chimiques sont successivement étudiés à la lumière du concept atomique moderne.

Puis, suivant pas à pas les expériences et les découvertes du début de ce siècle, nous pénétrons

au cœur même de la théorie atomique: structure électronique des atomes, avec l'étude détaillée de l'atome d'hydrogène; nature de la liaison chimique; description élémentaire et qualitative des orbitales moléculaires, après un exposé de l'essentiel de la mécanique ondulatoire.

Les derniers chapitres contiennent la partie des-criptive de la chimie minérale et organique. La façon de se comporter des éléments y est expliquée par la liaison chimique, la thermodynamique et la classi-fication périodique imaginée par Mendéléev vers 1870.

Une innovation qui sera certainement beaucoup appréciée, c'est l'introduction d'un chapitre sur la biochimie, sujet trop souvent négligé au niveau collégial. L'auteur y donne une description brève mais cohérente de ce vaste et important sujet, ce qui permettra aux étudiants de suivre sans difficulté des cours plus approfondis.

CHIMIE est un ouvrage complet, cohérent, forte-ment appuyé sur les expériences, capable de donner à l'étudiant de solides notions de chimie et d'orienter de nouveaux chercheurs vers cette spécialité.

A Change in Pic

At the recent Annual Meeting of the CAP it was decided to economize wherever possible in order to balance the budget for our organiz-ation in the coming year. Physics in Canada has been a major contributor to the budget deficits in the past, in spite of increased revenues from advertizing. Beginning with this issue, we are attempting to reduce production costs by producing the bulletin in the present format. In accordance with this, the entire editorial responsibility has been shifted from the national office to G. Michaud at the University of Montreal (for French content), and everything else to D. Brodie at the University of Waterloo. Contributors are asked to send all copy for Physics in Canada to either of the editors mentioned above.

The editorial office has not been over-whelmed with letters for publication in the last six months. Do physicists not feel strongly enough about anything controversial to put their ideas in print, or are we com-pletely satisfied with the status quo?

D. E. BRODIE

Letter to the Editor

Dear Sir:

Your editorial (May 1970) "A Crisis for Physicists in Canada" deals with a topic which has been a matter of concern for some time now. But it would be just as well to keep the prob-lem in perspective. It is probably true to say that a newly graduated Ph.D. in any discipline now has difficulty in finding work in his discipline, so that the problem for physicists is part of a much larger problem. For this reason it is probably unwise to imagine solving the problem for physicists alone by creating an idealized industrial system with a large R and D component.

Our problem is really to find the place of physics in a changed and unfamiliar situation. One hears less and less about standard of living and more and more about quality of living. Pollution, overpopulation, exhaustion of resources: these are the topics of the day, and they lead to the heretical concept of zero economic growth, as a phenomenon to be sought after rather than avoided.

There is of course no reason why we should not promote increased employment of physicists in fields in which they may be able to make

greater contributions than they have in the past. But my reason for writing this letter is primarily to remind physicists that economic need is not the sole motivation for the study and practice of physics. The funda-mental human purpose in one way or another is to become ever more civilized, and the justi-fication for intellectual and cultural activ-ities is surely that they are civilizing pursuits. A concern for the intellectual discipline of physics must be recognized as one of the criteria of a civilized society, and it is our task to impress this upon society. It will be an unfamiliar task for us, but it is in no respect different from the task which humanists have always had to face.

The Rime of the Ancient President (with apologies to Samuel Taylor Coleridge)

It is an ancient President, And he stoppeth one of three, 'Bye thy long grey hair and deep set eye, Now wherefore stoppst thou me?

The airport's doors are open wide My flight Is next to go; The school is out, my kids are home: My wife has phoned me so.'

He holds him with his skinny hand, 'There is CAP', quoth he. 'Hold off! Unhand me, greybeard loon' Eftsoons his hand dropt he.

He holds him with his piercing eye -The physicist stood still, And listens like an undergrad The President hath his will.

The physicist sat on a stone: He cannot but attend; And thus spake on that ancient man, The bright eyed President.

Je suis un homme du Canada Mais je ne suis pas complet, Je parle anglais; français je lis -Par effort sans ârret.

BRIEF HISTORY OF THE ASSOCIATION

As you are all well aware by now, the Canadian Association of Physicists is cele-brating its 25th anniversary. This seems a suitable time to recount a brief history of the Association. Some flavour of the birth of the Association can be obtained from reading the items in this year's Congress Bulletin. The precentennial years were characterized by a slow but steady growth and influence of CAP. Regular activities of the CAP consisted of the Annual Congress, a quarterly bulletin — Physics in Canada, summer schools, the CAP medal, lecture tours, high school prize exam-inations and university prize examinations.

During 1966-67, CAP had three subject divisions and eight committees. The permanent staff consisted of a secretary in the McMaster Physics Department, paid for half-time by CAP but in effect in the full-time service of the Association.

Besides the regular events mentioned above, toward the end of the precentennial period at least three special events of great importance took place. The first of these was the stat-istical survey of Canadian physicists carried out in 1964-65 by a committee chaired by Eric Vogt. Dr. Leon Katz, who was President of CAP at that time, told me that he had great dif-ficulty in persuading his Executive to take even this modest first step along the road toward involvement of the Canadian physics community in issues which we might now lump under science policy. It certainly would not have been possible at that time to go beyond a statistical survey.

In 1966-67 CAP conducted, under contract with the Science Secretariat, a very compre-hensive study, "Physics in Canada — Survey and Outlook". This study was carried out by a committee consisting of D. C. Rose (Chair-man), J. M. Robson, R. E. Bell, A. C. Hollis Hallett, and L. E. H. Trainor. The study was published just prior to the 1967 Congress and was the subject of lively discussion in the Congress and over ensuing months. The strong-est recommendation arising from the study was

La Physique au Canada / 105

that "special consideration must be given to strengthening the research effort in applied physics". One of the consequences of the Rose Report was that the applied physics committee of CAP, chaired by A. I. Carswell, produced a further study on applied physics in Canada which was published in 1968

The climax of phase one, or the precentennial years, of the Association came with the decision at the Annual Congress in 1967 to establish a national office in Ottawa.

THE NATIONAL OFFICE AND THE ASSOCIATION TODAY

Your homework assignment is to read the little red book otherwise known as the 1969-70 Annual Report of CAP. The red book contains a rather thorough account of the present state and recent accomplishments of the Association. I can now only touch on a few of the highlights and then pass on to some of the activities in our future.

The National Office was opened May 15, 1968. At present the National Office staff consists of our very hardworking and able Executive Director, Jean-Louis Meunier, his secretary and an accounts and membership clerk. They occupy 400 square feet of very crowded office space at 151 Slater St. in Ottawa. In the same building very conveniently are the national offices of the Chemical Institute of Canada, the Agricultural Institute of Canada, the Social Science Research Council, and the AUCC.

Some idea of the level of CAP activities today can be gleaned from the fact that we now have eight subject Divisions, 49 Committees and nearly 1200 full members. The full member-ship has increased by 15% during the last year.

Some important recent initiatives of the CAP include the co-founding of SCITEC, the launching of the socio-scientific study on how science is currently viewed in Canadian society, the institution of a second annual medal — the Herzberg medal, the beginning of a placement service and an annual meeting for corporate members.

Most of the special initiatives have made heavy demands on the manpower resources of the National Office. Meanwhile, routine affairs of the Association could not be neglected. As a result, the Office has been overloaded and the Executive Director seriously overworked. It is true, of course, that we have made use extensively of volunteer labour through our elaborate committee structure and we shall continue to do so. Nevertheless demands on the National Office will remain high. Matching the resources of the National Office to the needs of the CAP will continue to be a chal-lenging problem for the Association. However, we are successfully meeting the challenge now and will, I am confident, continue to do so. But I do not want to speak now of internal problems of our Association.

MANPOWER There is much concern presently with the

employment prospects for young Canadian physicists. Reports such as the Bonneau Report lead one to expect that the situation will worsen appreciably over the next few years. But we don't really know. Our first

106 / Physics in Canada

need is for reliable data on current and pro-jected supply of and demand for physicists in Canada.

In 1967 the Department of Manpower and Immigration carried out a statistical survey of highly qualified manpower in Canada. A year ago CAP received a $4000. contract from the Department "...to analyze the 1967 data ... and report on the supply and utilization of physicists and advise on the implications for policy and the design and conduct of future research and surveys". The analysis was carried out by Prof. R. C. Smith, a physicist at the University of Ottawa, and Prof. Baguly, an economist at the University of Western Ontario. The final report was recently accepted by the Department.

The data are now of course stale. Also, the study revealed the data to be less than complete in that there appeared to be a decline in the number of physicists employed in Canada from 1964-65, the year of the Vogt study, to 1966-67. CAP is recommending most strongly that the Association be fully involved, under contract from the Department, in any future manpower studies.

In the meantime we must continue to develop our placement service as best we can to make known to our graduate students the positions which are available.

But we must do more than that. We must see that positions are created. Physics has much to offer society beyond filling felt needs. We must develop the means for offering these gifts.

EXTERNAL RELATIONS

No society is an island. Our Association has not only internal relations with its members but also external relations with other Canadian scientific societies, physical societies in other countries, Canadian institutions of government, industry and education, and finally with the general public. A considerable part of CAP effort is devoted to cultivating these relations. I would like to mention briefly how I see our external relations at present and how I would like to see them develop.

I am very proud of the role CAP has had in the founding of SCITEC. Among the sixty-odd founding societies, only the CIC played a greater role than CAP. Regardless of how rapidly SCITEC develops (and it has financial difficulties) CAP has thus at least establish-ed close and friendly relations with its Canadian sister societies.

In the past the APS and AIP have played a somewhat avuncular role to CAP. I hope in the future the relations will be more fraternal. Soon CAP may be offering its members some AIP and APS journals. May I look forward to the day when Canadians need join among physical societies only the CAP to gain all those advantages of society membership which they might reasonably demand?

In the past, federal government agencies have not on the whole been a source of support for Canada's scientific societies although they have been a strong support to Canadian science. In particular, Government labor-atories employing large numbers of scientists

have not yet seen fit to accede to requests that they join the corresponding scientific societies as corporate members. With the exception of a few societies, the National Research Council has never provided direct financial support to the societies. NRC is now willing to provide indirect support through registration fees chargeable to grants. There has been much too strong a tendency for government to do studies in house even when they might better be done under contract by the scientific societies. I hope and I believe this situation is changing. A most important breakthrough is the recent large NRC grant to CAP which I shall describe shortly.

Finally, let me mention our image with the general public. The palmy days of physicist as hero are fading rapidly. I believe laymen were more impressed twenty years ago to learn that I was a student of physics than they are now to learn I am a professor of physics. Even our fellow scientists don't fully appreciate us. Let me recite one piece of evidence. Science Council has just finished a Delphi exercise on the federal support of basic research in universities. The exercise was conducted independently in six different groups: seminar participants, graduate students, conference participants, SCITEC Council, Science Council and Science Council Staff. All groups were unanimous in recommending that the relative expenditures on physics be cut and cut more severely than the support for any other science! We can no longer take affluence for granted.

DOUBLE JEOPARDY


GOALS AND PRIORITIES IN PHYSICS RESEARCH

Two weeks ago the CAP learned that the National Research Council has awarded CAP a grant of $48,000. to support a study on goals and priorities for physics research in Canad-ian universities under the support of federal agencies. The planned study can be thought of as a follow-up to the Rose Report. It will be more restricted in that it will consider only research in universities. It will be more pointed in that its recommendations, if followed, will necessarily affect the nature and rate of development of university research in physics in Canada for several years.

Until this year federal government support for university research in physics had been growing rapidly at the rate of the order of 20% per year. This period of rapid growth has now ended, and it can be expected to be followed by a levelling off period or alternatively a period of rational growth or even of reduction of support. A levelling off in growth rate raises difficult questions not encountered in an expansionist era. The planned study will provide the NRC with the advice of the Canadian physics community on these questions related to goals and priorities.

Some of the questions to be answered are: What is the supply and demand for physicists in the various subfields of physics? What is the contribution of Canadian physics and physicists to national goals for Canadian society? What is the balance of the physics program — are certain fields over-supported and others under-supported? What is the criterion for choice among physics subfields? What is the effect on Canadian science of promoting fashionable fields and reducing support for unfashionable fields? A number of Canadian physicists may find

it distasteful to consider questions of goals and priorities for university research in physics. Many among us feel that university research in physics ought to be entirely curiosity directed by the individual research professor. The amount of financial support provided by federal agencies should depend only on the research ability (or reputation) of the grant applicant. Indeed, this has been very nearly the system we have lived with up until now.

We live now, however, in the age of science policy, in which searching questions are being asked by the general public, by our elected representatives and by many scientists them-selves. Crudely put, the public and the politicians are asking, "Are we getting our money's worth?". In other words, are the public funds being spent on Canadian univer-sity research,including physics research, promoting Canada's national goals effectively? Various recent publications on Canada's science policy such as the MacDonald Report and the 0ECD Report, stimulate this trend. The forthcoming publication of the Lamontagne Report will reinforce the questioning process.

Federal agencies like the NRC, charged with the responsibility for the support of university research, are providing answers to questions of goals and priorities. It is important to the development of Canadian science that working scientists themselves establish goals and priorities on the basis of which decisions about support can be made. The CAP study will start by analyzing the way in which financial support for university physics research was distributed in the past. The study will also determine the recent rate of production of physicists and a projected rate to 1975. The study will gather data on employment of physicists in Canada. Finally and most important, the study will make recommendations concerning the allocation of NRC and AECB support to research in physics by physics subfields over the next five years under three different assumptions: 1. Rational Growth — constant support for

1971-72 followed by 20% annual increments until 19 75-76.

2. Status Quo — constant support for 19 71-72 followed by 4% (for inflation) annual increments until 19 75-76.

3. Reduced Support — constant support for 1971-72 followed by 5% reduction each year until 1975-76.

It is my hope and my earnest plea that the entire physics community will cooperate fully so that the study will represent the best thinking of the Canadian physics community on these difficult but unavoidable questions.

NATIONAL GOALS AS A FRAMEWORK FOR POLICY FOR PHYSICS

Canadian physics policy must be enunciated in terms of national goals for Canada. This has been recognized by the Science Council in their Report # 4, "Towards a National Science Policy for Canada". In that report, Science Council identified six national goals for Canada. The Science Council statement of national goals can be criticized in several respects but they must be commended for making the attempt to define national goals. It has been said that anyone with a little thought can write down an alternative set of goals which is as good or perhaps better. Because of the study that the CAP is about to launch on goals and priorities for physics research, we must have some definition of national goals. I have recently amused myself by playing "God", if you will, and writing down my national goals for Canada together with their elements as follows :

1. Health (a) Elimination of communicable disease (b) Prevention of genetic defects (c) Physical fitness (d) Repair of injury

2. Safety (a) Accident prevention (b) Elimination of crime (c) World peace (d) Protection from natural disaster


3. Material prosperity (a) Economic productivity (b) Fair distribution of net income (c) Price stability (d) Economic independence

4. Equable Environment (a) Pure air and water (b) Variegated and healthy flora and

fauna (c) Controlled weather (d) Functional and esthetic man-made

structures

5. Understanding (a) Intellectual appreciation of the

natural world (b) Intellectual and emotional under-

standing of fellow man (c) Self understanding

6. Adequate Challenge (a) Challenge to physical powers (b) Challenge to mental powers (c) Challenge to spiritual powers

7. Freedom (a) Freedom of action (b) Freedom of movement (c) Freedom of speech (d) Freedom of thought

8. Optimum Population (a) Optimum growth rate of population (b) Optimum geographical distribution

of population (c) Optimum total population

Why don't you have a go at it?

On His Retirement

When I consider how my year was spent Ere half my plans did some committee choose, And that one office which is death to loose Torn from me ruthless though my back still

bent To serve therefrom my colleagues and present My true account, lest they returning chide. "Doth CAP exact much service, fame denied?" I fondly ask, but Erich to prevent That murmur soon replies, "CAP needs Neither your work nor its own awards. Who best sit on committees, they serve it best. Its state is kingly: hundreds at its bidding

speed And fly o'er land and ocean without rest; They also serve who only pay their fees."

The Herzberg Medal

A. E. DOUGLAS

The President presents a copy of the new Herzberg Medal to Dr. G. Herzberg.

The design of the Herzberg Medal is an accurate representation of the potential curve of the ground state of the hydrogen molecule. Although Dr. Herzberg's research has ranged over a wide area, so many of his abiding Interests converge on the hydrogen molecule that it seems particularly appropriate that this design should be chosen as a symbol of his contribution to science.

Gerhard Herzberg has always focused his interest on simple systems, systems in which many simple properties can be both calculated and predicted precisely. The hydrogen molecule being the simplest stable molecule has been the subject of particular attention. In 1927 he wrote his first papers on hydrogen and in 1969 he published a new accurate value for the dissociation energy of hydrogen. The end is not yet in sight and, at this time, he is engaged in a study of the many hundreds of electronic states of hydrogen which lie near the ionization limit.

Other abiding interests of Gerhard Herzberg have been astrophysics, new experimental tech-niques and the so-called "forbidden" transi-tions. In 1948 at Yerkes Observatory he constructed a new improved type of absorption cell in which the absorption of 50000 meters atmospheres of hydrogen could be examined. He was able to detect the two "forbidden" tran-sitions which are shown on the design,and sub-sequently these transitions were used to determine the amount of hydrogen in the atmo-spheres of stars and planets. Thus we trust that, in the desigiv of the Herzberg Medal, we


have created a permanent reminder of at least a small part of the work of a brilliant and dedicated physicist.

The Herzberg Award for 1970 to Rudolph Roland Haering

J. F. COCHRAN

R. R. Haering

The Herzberg Medal of the CAP has been struck for the purpose of giving recognition to an outstanding young Canadian physicist who, in the year of the award, is not more than 38 years of age. In choosing R. R. Haering as the first recipient of this medal, the Awards Committee has set a standard of excellence which, if it can be maintained in the future, must surely give us all a little more reason to be proud of being Canadian physicists. It must also provide reassurance to any of us who may feel that there are no suitable replace-ments on the horizon for outstanding Canadian senior scientists such as G. Herzberg himself. Most physicists in Canada know Rudi Haering, either personally or by reputation, but perhaps not all are familiar with his background so I would like to give a brief summary of his Cur-riculum Vitae.

Rudi Haering was born in the early Spring of 1934 in Basle, Switzerland. His parents immigrated to Canada in 1947, and the family made its home near Kaslo, B.C. (Kaslo is a small town of approximately 1000, located on the shores of Kootenay Lake, 400 miles east of Vancouver. In my opinion it is located in the most beautiful and climatically congenial part of Canada.) At the age of 16 Rudi became a freshman at the University of British Columbia.

At the end of this year he was awarded the Royal Institution Scholarship in Arts and Science. Rudi Haering has always attributed this splendid performance to the fact that Kaslo had no senior matriculation program at the time that he was finishing high school, so he was forced to learn his physics and mathe-matics via correspondence courses and therefore free of the influence of misinformed teachers. We all know that this is nonsence. The great consolation to those of us who teach is that it is practically impossible to ruin an outstand-ing student.

I will not bore you with further details of his undergraduate and graduate career. Suffice to say that he was supported by scholarships, N.R.C. Bursaries and N.R.C. Studentships throughout his period of formal education. He was awarded the B.A. degree in Honours Maths, and Physics in 1954, the M.A. degree in Physics in 1955, both from the University of British Columbia, and the Ph.D. degree from McGill University in 1957. At McGill University, Rudi Haering worked under the supervision of Professor P. R. Wallace who assigned him the problem of investigating the properties of graphite through the application of band theory. It is rumored that Professor Wallace was per-turbed by the dispatch with which his assigned projects were executed, and finally had to agree to let Rudi present his Ph.D. thesis after a mere two years in residence because he could not think of any further property of graphite which was amenable to calculation.

Following the completion of his Doctoral thesis at McGill, Rudi Haering spent one year in England as a N.R.C. Postdoctoral Overseas Scholar under R. E. Peierls, F.R.S., at the University of Birmingham. He then returned to Canada for two years as Assistant Professor of Physics at McMaster University, but was sub-sequently recruited to the I.B.M. Laboratories at Yorktown Heights, New York, U.S.A. At the I.B.M. Laboratories, Rudi Haering's talents for working with experimentalists made him an extremely valuable member of the organization and he found himself receiving one promotion after the other. His concern mounted as he became further and further removed from direct involvement with physics and more involved in management, and so in 1963 he cooly decided to leave the organization and return to Canada, taking an appreciable cut in salary in the process.

Rudi Haering went from I.B.M. to the Uni-versity of Waterloo as Professor of Physics in 1963. In 1964 he was sought out by G.M.Shrum, then Chancellor of the newly-formed Simon Fraser University, to build up a physics depart-ment at one of the first of Canada's instant universities. Others less involved than myself must judge his success. However, I am free to state that it was Rudi Haering's decision to establish a department with a strong bias toward solid state physics research, and it is a fact that our department of 19 members does constitute one of the strongest solid state groups in Canada.

In the Fall of 1968 Rudi Haering stepped down as Head of the Physics Department at S.F.U. to help our University through a period of crisis by serving as its Acting Vice-President Academic. Peace was restored to campus by the


Summer of 1969 and he resigned the Academic Vice-Presidency to return to the department as Professor of Physics. Indeed, the only crit-icism that I can make of Rudi Haering is that having built up the Physics Department, and having served extremely ably as its head, he then became one in the vanguard of those advocating that departments be organized under elected Chairmen serving for a limited term.

In between serving as an outstanding educator, academic administrator, and research scientist, Rudi Haering has found the time to serve Canadian physics in other ways. I would like to enumerate some of the major positions which he has held during the past five years. 1965-67 Chairman, Theoretical Physics Division

of the CAP. 1967 Chairman of the Committee which pre-

pared the contribution from the Solid State Division to the Rose Report on Physics in Canada. (Physics in Canada, Survey and Outlook, Special Study No. 2, May, 1967. Science Secretariat, Privy Council Office, Ottawa.)

1967-70 Member, N.R.C. Physics Grants Selection Committee.

1968-present Editor, Canadian Journal of Physics. 1969-present Member, D.R.B. Advisory Committee

for Physics.

Rudi Haering is the author or co-author of some 39 publications in physics. The topic of these publications range over the field of solid state physics — from the properties of metals, to the behaviour of semiconductors. References to his eight most important pub-lications are appended; his catholic range of interests is apparent from their titles. One of his major contributions has been to the understanding of the behaviour of thin film transistors. This interest has in fact led him to the brink of a new career in physics — that of the Scientific Entrepreneur. Just this Spring Rudi Haering has been instrumental in setting up a company, based in Vancouver, to exploit thin film technology. The company is called "Canadian Thin Films", and one hopes that it represents the beginning of a new trend in building up businesses in Canada based on advanced technologies. I confidently predict that Canadian Thin Films will flourish under Rudi's direction, and may ultimately offer the possibility of providing jobs for us all if and when students decide to boycott physics altogether.

I hope that this brief sketch has conveyed some idea of why I am so very pleased that Rudi Haering was chosen to receive the Herzberg Medal. I appreciate very much having had this opportunity to attest to my high regard for Rudi Haering both as a physicist and as a person. Selected References

Special Medal Awarded to Wilfred Bennett Lewis on the Occasion of the 25th Anniversary of the Society

G. C. LAURENCE

Wilfred Bennett Lewis began his research career in 1930 under Lord Rutherford in the Canvendish Laboratory by investigating the energies of alpha particles from radioactive substances. Continuing at Cambridge as a Research Fellow of Gonville and Caius College, and as a University Lecturer, he worked with Cockcroft on the disintegration of nuclei by accelerated particles, and took part in the design and operation of the Cambridge cyclo-tron. He was one of the pioneers in the use of electronic amplifiers in nuclear research and in the development of binary scalers.

Following the outbreak of war in 1939, Dr. Lewis worked on the development of radar, first at the Bawdey Research Station of the Air Ministry, and eventually becoming Chief Superintendent of the Telecommunications Research Establishment in Malvern.

In Canada, as construction of the NRX reactor neared completion as a wartime develop-ment, It was decided to continue in peacetime the operation of NRX and its associated facilities as a national laboratory for nuclear research and the development of its peaceful applications. Dr. Lewis was appointed as Director of the Atomic Energy Research Division of the National Research Council in 1946 to direct the scientific activities centered about the NRX reactor at Chalk River.


W. B. Lewis

W. B. Lewis, more than most, recognized the great opportunities for research provided by NRX and directed his genius and energy to exploiting them. He recruited able scientists and expanded the laboratories and equipment. With detailed and critical interest in all aspects of the scientific activity, including physics, chemistry, metallurgy and biology, he directly inspired much of it. Under his leadership, the Chalk River establishment became recognized as one of the leading nuclear research centres of the world.

His qualities of leadership were tested and proven during those despairing days in 1952 when many believed that NRX had been damaged beyond repair and that with it might disappear the great promise of nuclear energy research in Canada. He sustained the morale of the staff and organized reconstruction to produce a better, more powerful, NRX. Largely owing to his infectious enthusiasm, it was decided to construct NRU, then the most power-ful, and still the most versatile, nuclear research reactor in the world.

When administration of the Chalk River Laboratories was transferred to the newly-created Atomic Energy of Canada Limited in 1952, Bennett Lewis organized the research and development that became the basis of the Canada heavy water natural uranium nuclear power station concept. Some of the more important and difficult problems delaying the attainment of economic success derived from the effects of neutron radiation on the phys-ical, metallurgical and ceramic properties of materials. He promoted, inspired and partic-ipated in research that overcame these difficulties, while adding to knowledge of the solid state of matter. These advances, as well as his studies of fuel cycles, played a very important part in making natural uranium the cheapest of nuclear fuels. By his own ideas, and by the stimulation of others, he has contributed to all important aspects of nuclear power development — fuels, metallurgy, reactor physics, safety, instrumentation, and engineering generally.

He is a Fellow of the Royal Society of Canada and recipient of a number of honorary degrees. Recognition of his services to Canada found expression when he was the first to receive the Outstanding Achievement Award of the Public Service of Canada in 1966, and in his appointment as Companion of the Order of Canada in 1968. Yet his fame and influence are international. He is a Fellow of the Royal Scoiety of London, and a Commander of the Order of the British Empire. He received the American Medal of Freedom with Silver Palms in 1947, and the Atoms for Peace Award in 1967. He is a Past-President of the American Nuclear Society, and has been for years a member of the Scientific Advisory Committees of the United Nations and of the International Atomic Energy Agency.

He has always emphasized the importance of good equipment for research, and under his direction the Chalk River National Laboratory had the first tandem van der Graaff accelerator and the first transistor 100 channel kick sorter, and was one of the early users of electronic computers in research. His con-viction that nuclear spallation has far-reaching possibilities for the release and industrial use of nuclear energy, and as a source of radiation for pure and applied research, led him, with the enthusiastic col-laboration of his colleagues, to explore many ideas for a powerful particle accelerator as a first step towards the development of spallation as a source of commercial energy, providing at the same time a powerful instrument for research in neutron,meson and solid state physics. Whatever may be the future of the specific proposal that has come to be known as ING, many of the ideas that these studies have engendered will surely survive to take substantial form as important advances in science and technology.

The outstanding qualities that have borne onward his career are his purposeful persist-ence, a compelling urge to apply for the material benefit of society that deep and detailed understanding that has come to him as an insatiable student of pure science, and a rare intuition that carries his mind beyond the reasoned thought that awakens it. He has strongly supported fundamental science at Chalk River and his encouragement of it is well known in our universities.

It is fitting, on the occasion of the Twenty-fifth Anniversary of the CAP that this Special Medal should be struck to honour Wilfred Bennett Lewis for his great con-tributions to the advance of physics and its application in the service of the Canadian people.

RESPONSE

In his response to the award, Dr. Lewis made several important remarks. In particular he expressed how honoured he felt with the award and that he was particularly pleased since so many physicists, whom he knows and appreciates, were present and approving the award. He noted that in some degree the award recognized the value of the Canadian Nuclear Power Program to which many had contributed, but this introduced a note of sadness because


the award implied that success was already accomplished whereas there remained very much to be done.

In the original forecast of the Canadian Nuclear Power Program that he proposed in 1953, he indicated that by the year 1980 it should save the Province of Ontario the purchase of American coal to the value of three hundred million dollars a year. We still have some way to go before reaching 1980 and although the estimate still looks good, much more con-struction and development is necessary to achieve it. For the long term the prospect for heavy water reactors continues to be bright and he expects the organic cooled heavy water moderated reactor to return to the scene and take the lead by 1985 using both uranium and thorium fuel.

He recalled that up to 1939 there was reason to be concerned that no means was seen for feeding all the people already born in the world. In fact millions have died from under-nourishment and we are still a long way from raising the life-span and standard of living of those in developing countries to be close to those enjoyed in the industrialized count-ries. The discovery of nuclear fission in 1939 had led to the vision that we could go ahead to give the opportunity of a long and productive life to a large world population even of fourteen thousand million. Moreover, the nuclear power system developed in Canada shows promise of making a major contribution. Canada has already cooperated with India in building their nuclear power program.

They were disappointed two years ago when the ING Project was turned aside for although it would not have been essential to an adequate development of nuclear power, yet it bore promise that it could make in time a signifi-cant improvement and it would have broadened the Canadian base considerably. He concluded with the remark that there is much to be contributed yet by physics to the world development of nuclear power.

The Sixteenth Medal for Achievement in Physics, 1970, to Alexander Edgar Douglas

G. HERZBERG

I consider it a great privilege to be asked to present this year's recipient of the CAP Medal for Achievement in Physics. I am honoured to be asked to do this even though I was not a member of the Selection Committee, whose choice, of course, I wholeheartedly approve. I have been associated with the winner of this year's Medal for a very long time. I have therefore been able to appreciate

at close range cfae merits that have earned him so unquestionably the high honour that the CAP is conferring on him today.

Alexander Edgar Douglas was born in Melfort, Saskatchewan, where he grew up on a farm. He had much of his schooling in a one-room rural school. He came to the University of Sask-atchewan in 1936 and obtained his B.A. degree with high honours in 1939 and his M.A. degree in 1940. He started work towards his Ph.D. degree at the University of Minnesota, but interrupted this work in 1941 in order to help the Canadian war effort by joining the National Research Council where, until the end of the war, he worked in acoustics, mainly on U-boat detection by underwater sound. After the war he spent two years, 1946-48, at Pennsylvania State University with Professor Rank, and obtained his Ph.D. degree there in 1948. This was just the year that I came to the National Research Council, and I considered myself extremely fortunate when Alec Douglas agreed to join me in building up a laboratory in spectroscopy at the National Research Council. Alec Douglas rose rapidly through the ranks until, in 1967, he was made Associate Director of the Pure Physics Division, in 1968, Director of the Applied Physics Division and, a year later, Director of the recombined Pure and Applied Physics Divisions.

Alec Douglas's scientific work may be con-sidered under three headings. First of all, he discovered a considerable number of new molecules by means of their spectra, starting with his M.A. thesis in which he observed the spectrum of diatomic boron. A particularly important discovery was that of the nature of the carrier of a spectrum first observed in comets (the so-called 4050 group), which he showed conclusively to be due to the C3 mole-cule, a molecule that up to that time had not even been postulated by kineticists as an intermediate in chemical reactions but is now well-known to play an important role in the evaporation of carbon and in other chemical phenomena. Other spectra of new molecules that he and his associates discovered were BN, CN+, CH+, Si2, NF and S1H+. In addition to new molecules he also studied a number of new spectra of known molecules. Among these I should like to mention particularly the first laboratory observation of a spectrum observed by Meinel in the aurora. This is a transition of the N2 ion and was fully analyzed by Douglas.

The second group of investigations of Douglas refers to new techniques in spectros-copy. Right from the beginning, when Alec Douglas was a graduate student at Saskatchewan, he showed a quite unusual experimental skill and he has in the course of time further per-fected this skill, which allows him often to do a quick experiment on a difficult problem all by himself, essentially with string and sealing wax in the old style. At any rate, the new techniques that I want to mention are, first of all, the construction of the first really large, 10 m, vacuum grating spectro-graph, which was later copied in two other laboratories; second, his development of a method of studying the Zeeman effect in the spectra of stable and transient molecules by a flash technique, somehwat related to a method

A. E. Douglas

used by Kapitza in the 1920's and, finally, the development of methods of studying transient species both in emission and absorption in the afterglow of electric discharges.

The third group of investigations deals with the interpretation of molecular spectra. Under this heading I should like to consider Douglas's analyses of known spectra which had previously not been satisfactorily analyzed. Examples are the analyses of the ultraviolet and vacuum ultraviolet absorption spectra of NH3, the ultraviolet absorption spectrum of Mg2, and the partial analysis of the violet absorption spectrum of NO2. All three (and others which I have not mentioned) are extremely complicated spectra. Their analysis by Douglas and Hollas, Balfour and Huber has required real insight and in all three cases the analysis has supplied extremely valuable information about the structures of these molecules (e.g., NH3 was found to be planar in all its excited states, in contrast to its pyramidal structure in the ground state).

Finally, under the same heading (interpret-ation of molecular spectra), I should like to mention the by now almost classical paper that Douglas published only four years ago on the anomalously long radiative lifetimes of mole-cular excited states. This study was suggested by some of the strange and apparently contra-dictory results of investigations of NO2 and other simple triatomic molecules; it throws considerable light on the phenomenon called internal conversion by many physical chemists. According to Douglas, it is very closely con-nected with the mechanism of so-called perturbations in molecular spectra. I have found this paper quoted in almost all of the many papers that have been published since then on the subject of internal conversion, inter-system crossing and the like.

So much for the published record of Alec Douglas's contributions to physics, and to spectroscopy in particular. There are in addition innumerable unpublished contributions which only appear in the thank-you notes at the end of almost all the papers that have been


published by the spectroscopy group at NRC. His keen interest in all the work going on, his ability to see immediately the weak points in any speculation or proposed experiment, his willingness to make significant suggestions for the experimental method used in a given problem and for other improvements in most of the work were of the utmost value to all members of the group. It is no exaggeration to say that he has had a major share in the scientific output of the spectroscopy laboratory since its in-ception, quite apart from his own published work.

Alec Douglas is not only highly successful in purely scientific work but his judgment on everyday problems of policy, of administration and related topics is unfettered by preconceiv-ed ideas and goes down to the heart of the matter in every instance. It was therefore not surprising, and was a considerable source of satisfaction to me personally,when the committee charged with the problem of finding a new Director of the Applied Physics Division unani-mously decided that Alec Douglas was the right man for the job and, at the same time, recom-mended that Pure and Applied Physics should be recombined to form one Division of Physics, which he now heads. Much as I regret that this new position takes Alec Douglas away from his own scientific work, more than I am sure he likes, there is no question in my mind that NRC has been extremely fortunate in finding a man of his accomplishments and his vision to carry on this job.

Alec Douglas was elected to the Royal Society of Canada in 1954 and the Royal Society of London this year.

It is a great privilege for me, Mr. Presi-dent, to present to you, at the request of the Selection Committee, Alexander Edgar Douglas for the award of the CAP Medal in recognition of his pioneering work in molecular spectros-copy which has won him world renown, and for his contributions to physics in Canada.

Erich V o g t - A Profile

T. D. NEWTON

The title is traditional but a profile is inadequate for Erich Vogt; he will always take the direct approach.

Erich Vogt is a straightforward man who might, at first sight be taken for a farm hand, — about six feet, broad, hair black with one white spot now spreading somewhat, suit usually rumpled, tie (if any) askew. His first words will be politely hesitant but then,if he is interested, the words will come tumbling rapidly but not so fast as his thought. And, if physics is the topic, the listener will soon appreciate why Erich is the President of the CAP.

Erich Wolfgang Vogt was born into a hard-working family in Steinbach, Manitoba in 1929.


E. Vogt

The country boy appearance is natural. After taking a B.Sc. (1951) and M.Sc. (1952) from the University of Manitoba, Erich married Barbara Greenfield and took her to Princeton where he worked with Eugene Wigner to obtain a Ph.D. in theoretical physics in 1955. His doctoral studies of nuclear reactions began a series of about 50 research papers nearly all of which deal with general or specific cases of nuclear reactions. These papers were written at Chalk River (1956-65) where he went after a year in Birmingham as an N.R.C. post-doctoral fellow, in Rochester (1958-59) and at the University of British Columbia (1965- ).

Vogt was the first to demonstrate that the Wigner formalism could be used to give a pre-cise many-level fit to several closely spaced resonances; he has discussed the relation of the shell model (optical model) and other phenomenological models to the general reaction formalism and the effects of the "thick nuclear surface". He has helped to disentangle the effects of statistical fluctuations in cross-sections which used to be confused with broad resonances. In most cases these ideas have been worked out for particular nuclei. Recently his interest has centred on alpha-particle formation and emission and experiments which may be done with mesons.

This list of subjects is, of course, in-complete but it indicates the range of Erich's published work. In these papers the ideas are clearly stated, the consequences worked out and related to experiment. It is not always neces-sary that the ideas be derived from a unified theory. Although Wigner was Erich's professor, Vogt's work is more in the Weiskopf than in the Wigner style.

These research papers form a fine con-tribution to theoretical nuclear physics but they are not Erich's only contribution to physics in Canada; other effects derive from his wide general knowledge, unbridled curiosity, boundless energy and willingness to undertake any task which will assist in the development of physics and science in general.

Erich has edited Physics In Canada; he is

Editor of Advances in Nuclear Physics; he has been a Canadian editorial advisor for Physics Letters since it was founded. He and A1 Bromley edited the Proceedings of the International Conference on Nuclear Structure at Kingston in 1960 and Erich was on the Advisory Committee for the similar conference on Properties of Nuclear States at Montreal in 1969. These and other editorial tasks performed by Vogt form a significant part of the Canadian contribution to the world development of nuclear physics.

Since 1965 Erich has been teaching at U.B.C.; there can be no doubt that his classes are lively. However two of his other activities, — as Associate Director of TRIUMF, the only large-scale project for physics which has sur-vived the recent Canadian economic climate for science, and as a member of the Macdonald Com-mittee have more immediate and wider conse-quences for Canadian science. The report of the Macdonald Committee — appendix 2 bears the unmistakable Vogt imprint — has already had an effect on Canadian science and will surely have more, while TRIUMF is a large step forward for experimental physics in Canada.

Together with this scientific life Erich and Barbara are bringing up a family of five children. Some years ago residents of Deep River would often see Erich giving Barbara a break by taking the children for a walk, in his own style, one child on each shoulder and pos-sibly one under each arm.

This personal and energetic approach is characteristic of the man. We can be sure that the responsibilities of the President of the CAP will be capably shouldered and energetical-ly carried out or extended during this year.

The Employment Situation for Physicists with Higher Degrees

P. R. SMY

At the Annual CAP Congress an information discussion on the above topic was conducted by a panel consisting of Drs. Atherton, Betts, Chisholm, Elliot, Le Roy and Vogt, plus, very appropriately a graduate student — Mr. Art Burgess. That the subject was of considerable interest was evident from the audience of several hundred which attended the discussion rather than choosing to attend one of the eight sessions dealing with scientific topics being held at the same time.

Mr. Burgess initiated the discussion by giving various estimates for the supply and demand of Ph.D.'s in physics over the next few years. For 1972 he forecast a surplus of about 400 Ph.D.'s. In terms of the relative supply of Ph.D.'s it was Interesting to note that at present the per capita production of Ph.D.'s in Canada exceeded that of the U.S. and on present trends would be double that of the U.S. by 1980.

Reaction to these figures was mixed but in general most panelists accepted that even if there were no problem now there would be a problem In the next few years. Dr. Betts noted that we could expect some more official figures and projections shortly. The broad nature of the panel was reflected in the wide range of remedies suggested. These ranged from a call to all physicists over 35 to "retire" to other professions to the suggestion that all Ph.D. supervisors should resign their tenured professorships and then compete for jobs on equal terms with their numberous ex-students. Other proposals received more general support. Dr. LeRoy of the National Research Council felt that universities were

partly responsible in that they were largely insulated from society and their graduate schools possessed a nearly insatiable appetite for graduate students. However, he was unhappy about a rigid restriction of graduate student numbers by, for example, prohibiting student support on N.R.C. operating grants. In this opposition to rigid controls he was echoed by Dr. Vogt who hoped that it would always be possible to hire some non-Canadians. Dr. Chisholm of Northern Electric made the point most forcibly that as far as Ph.D.'s were con-cerned there was an "impedance mismatch" between university and industry. Dr. Chisholm con-tended that the "product" was wrong and attributed this in part to the fact that many professors have no experience of industry. In consequence the average Ph.D. took about one year in industry before he became useful. Dr. Chisholm emphasized that the top-notch Ph.D. was never any problem — he was referring to the average Ph.D. He believed that things might improve if more professors took sabbat-ical leave in industry and in this way acquainted themselves with the needs of industry. Several panelists expressed the hope that some physicists would turn to other in-teresting areas of research such as Oceano-graphy (LeRoy) and Transportation (Atherton) although it must be admitted that some of the more traditional areas for diversification such as Electrical Engineering are having their own employment problems at present.

Various comments were made by members of the audience. Dr. Purcell, President of the American Physical Society, stated that the situation in the U.S. was not good at present and that it could be expected to get worse for another year. Another speaker received general support when he stated that to some extent the present "crisis" was a "crisis of expectations" rather than a severe unemployment situation.

For graduate students at the discussion the lesson to be learned was fairly clear, i.e. , get a degree and job as quickly as possible before the situation gets worse. For Ph.D. supervisors, however, the discussion, although by no means unanimous in its outcome, raised some questions which are not at all easily answered:

(a) Are the admission standards high enough for Ph.D. students?

(b) Even if students are of high standard, are we still producing too many Ph.D.'s?

and (c) Are the students being provided with research projects and background training that will fit them for a wide variety of industrial as well as academic positions? * * * * *

Towards Participation at Batavia

L. RESNICK

The prospects for Canadian participation in the experimental programme at the first of the next generation of high energy accelerators presently under construction at Batavia, Illinois, are now quite good. At a time when some existing accelerators in the U.S. are being phased out and, with progress in a U.S.-Soviet exchange agreement that would see Soviet physicists conducting experiments at Batavia, the focus in high energy physics is increasingly toward the Batavia machine. It was therefore quite clear that to Canadian high energy physicists the question of partic-ipation was a vital one for the continuation of a viable high energy programme.

In the Spring of 1969, the Canadian 200 Gev Study Group prepared a detailed report centred on the Batavia accelerator, entitled "A Particle Physics Programme for Canada" (PPPC). Among its major recommendations were:

(1) Canada would participate "directly" in the accelerator laboratory, as distinguished, for example, from the construction of a particular experimental facility or area.

(2) As the accelerator was in the beginning stages of construction then, the "direct" participation envisaged a contribution to-ward the capital cost of the accelerator itself. The figure suggested was $4 million per year, over five years, and was exclusive of expected escalation of operating costs for the Canadian high energy physics com-munity.

(3) A Canadian Universities Research Associa-tion (C.U.R.A.) would be formed to co-ordinate the Canadian programme.

In the Summer of 1969, CAP undertook, a survey of the Canadian physics community for

opinion on the subject. Of the respondents to a questionnaire, 62% indicated that without reference to specific mechanisms or time scales they were in favour of a significant expansion of experimental high energy physics in Canada, while 56% of the respondents supported the specific PPPC proposal. The recommendations of the CAP Survey Committee and the results of the questionnaire were passed on to the NRC Advisory Committee on Physics to conform to an undertaking when NRC supported part of the cost of the survey. A summary of the recom-mendations is given in Physics in Canada, January 1970, p. 23.

The NRC Advisory Committee on Physics, in its report to NRC in the Autumn of 1969, did not recommend the acceptance of the specific proposal outlined in PPPC, but did favour the continued growth of a Canadian high energy experimental programme. NRC subsequently established an ad hoc committee which met with representatives of the National Accelerator Laboratory, the Universities Research Associa-tion, and the U. S. Atomic Energy Commission at Batavia in December, 1969.

NRC suggested a figure of $1 million per year as a reasonable ceiling consistent with present Canadian resources while the Americans indicated they would regard $1 million as a minimum contribution to accompany a serious participation programme. Dr. R. R. Wilson, Director of N. A. L., also made it clear that Canadians, like other non-U.S. physicists, could not look forward to the privileges of using the accelerator without contributing to the cost of its operation.

In April, 1970, Dr. Wilson announced that, because of technological advances, the comple-tion date for the accelerator had been pushed forward by one year, with a beam expected in the Summer of 1971. Furthermore, the maximum energy would be 400 or possibly 500 GeV, rather than the initially planned 200 GeV during the first phase of operation. The original proposal of Canadian participation in the capital cost of the accelerator was there-fore obsolete, and the relevant question as of June of this year was the possibility of participation in the future experimental pro-gramme via a contribution of some $1 million annually to the operation of the laboratory.

At its June, 1970, meeting, the National Research Council once again considered the problem and adopted the following resolution: "Council accepts the principle of participation in the operation of the Batavia accelerator and undertakes to implement this as soon as its financial situation permits. In the meantime, It authorizes the Vice-President (University Support Programme) to put a sum of up to $200,000. annually at the disposal of the Director, National Accelerator Laboratory, as a retainer to keep the participation offer open".

On related fronts, an Institute for Particle Physics is being formed by those institutions in this Country actively engaged in high energy physics. This Institute, rather than the proposed C.U.R.A., will co-ordinate and oversee the Canadian high energy programme. In addition, a Division of Particle Physics is being formed within the CAP. The outlook at present for high energy physics in Canada is therefore reasonably bright.


Universities and the Community

The following is a summary of the Presidential Address, given at 4:00 p.m. on Tuesday, 5 May, 1970, by Dr. M. R. Gavin, CBE, FInstP, President of the Institute of Physics and the Physical Society.

The universities have always had two main functions to serve (I) as seats of learning and (ii) as sources of manpower for the com-munity. There need not necessarily be any serious conflict between these functions and it is most important for both the universities and the community that these two functions be maintained. Some of the problems of adapting the university/community relationship to a highly industrial economy are discussed historically and compared with the corres-ponding situation in developing countires.

The State is the main source of university financial support and this presents a threat to university freedom and autonomy. The existence of the University Grants Committee and the Research Councils have so far provided ample protection for universities from govern-ment interference but it is most important that the universities should accept some direction and control from these bodies — bodies which are largely academic in their membership. The alternative would be direction and control from civil servants or politicians. These problems are discussed in terms of the research effort in universities in pure science and technology. In the past a high proportion of the money available for research has gone to "big science" and to nuclear physics In particular. Now the S.R.C. are trying to en-courage more university research effort in engineering and technology whilst still giving reasonable support to "big science". These issues are illustrated by reference to the history of the 300 Gev accelerator project on the one hand .and the S.R.C. support for control engineering on the other.

Academic freedom for dons has been a cher-ished principle in universities. Today students are insisting that the principle is equally applicable to them. Their efforts, associated with a realisation of the power of massed pro-test, have raised serious problems for the universities, and in the long run, for the community and the world at large. This is part of the world-wide struggle of the under-privileged against traditional authority. It is most important that the British university system should set an example by showing that reason and persuasion can triumph over disruption and force.

La physique a l 'UQM

G. MICHAUD

L'Université du Québec à Montréal (UQM) a ouvert ses portes en septembre 69. On s'attend à y décerner 25 baccalauréats en physique par année à partir de l'an prochain, et on espère y recevoir des étudiants gradués dès l'année académique 1971-72. Nous avons rencontré M. Roges Deserre, directeur du département de physique. Il nous a appris ce qui s'est passé, se passe ou se passera, en physique à l'UQM.

L'UQM est née de la fusion du Collège Sainte-Marie et des Ecoles Normales de la région. Le département de physique en a hérité douze professeurs, auxquels quatre nouveaux sont venus se joindre pour l'année universitaire 69-70. Quatre d'entre eux ont un baccalauréat, neuf une maîtrise et trois un Ph.D. (ou du moins espèrent avoir un Ph.D. en septembre 70).

Pourquoi un département de physique mais aucun département de sciences appliquées? Il y avait déjà un département de physique à Sainte-Marie et il y avait des professeurs de physique dans les Ecoles Normales. Il n'y avait aucun professeur de sciences appliquées. On n'a apparemment fait aucune étude pour déterminer dans quels domaines on avait besoin de diplômés. On a voulu continuer dans la vole des Ecoles Normales. De même, il y a quarante professeurs de mathématiques et on s'attend de former 200 gradués par année en mathématiques.

A l'Université du Québec, les professeurs ont trouvé un cadre administratif nouveau. Les décisions au sujet des programmes d'étude, des critères d'admission et de promotion sont prises par les modules, où les étudiants sont, en pratique, en majorité. Les modules décident quels cours seront enseignés. Ils ont tendance à demander plus de cours que les professeurs ne peuvent enseigner et ne sont souvent pas d'accord avec les professeurs sur les critères de correction des examens. D'où beaucoup de tension.

Chaque professeur enseigne six heures par semaine, huit mois par année. Cette année six professeurs collaboraient à des programmes de recherche dont trois en physique nucléaire (à l'Université de Montréal et à l'Université McGill). On n'a pas l'intention d'engager de nouveaux professeurs en physique nucléaire ni de lancer un projet de recherche en ce domaine; ceux qui continueront devront le faire en collaboration avec les groupes établis dans d'autres universités.

Pour 1969-70, le département de physique a obtenu du gouvernement du Québec, $120,000.00 en fonds d'Investissement pour la recherche. Pour 70-71, on a demandé $186,000.00. Une partie de ces fonds sert à compléter les collections de revues scientifiques. On veut aussi lancer un projet de recherche en physique des plasmas en collaboration avec l'Université de Montréal.


Les nouveaux projets de recherche sont choisis par l'assemblée des professeurs. Aucune décision n'a encore été prise, sauf pour les plasmas. On parle de spectroscopie et de physique de l'état solide. En principe, la recherche devrait surtout se faire en collaboration avec l'Institut national de Recherche scientifique qui a annoncé la construction de laboratoires à Varennes, à quelque 25 milles de l'UQM. Aucun contact n'avait encore été établi en avril dernier.

C'est l'assemblée des professeurs qui choisit les nouveaux professeurs. En 70-71, il y aura un nouveau professeur, qui sera spécialisé en physique des plasmas, conformé-ment à l'orientation choisie. On exige des nouveaux professeurs qu'ils aient un Ph.D. ou l'équivalent, un doctorat d'état, par example. Les nouveaux professeurs doivent parler français. A compétence égale, on donne la préférence aux canadiens.

On ne sait pas combien de nouveaux postes seront disponibles en 1971-72. Cependant, si on accepte des étudiants gradués cette anneé-là il devra y avoir plusieurs nouveaux professeurs.

Mais le département de physique de l'UQM sera-t-il prêt à recevoir des étudiants gradués en 1971-72? Les professeurs dont il a hérité ne semblent pas préparés, en général, pour diriger des étudiants gradués. Au moment où il y a un surplus de Ph.D. en physique, il nous semblerait inopportun de créer une école où les étudiants ne seraient pas mieux encadrés. Ils auraient peut-être de la difficulté à se trouver des employeurs.

CAP UNIVERSITY PRIZE EXAMINATION

The CAP University Prize Examination is a nation-wide competition among senior under-graduates studying physics. One purpose of the competition is to stimulate individual scholarship. The overall results reflect the merit of different universities and the exam-ination may be expected to have an effect on the quality of teaching in Canadian univer-sities .

The Educational Trust Fund provides a first prize of $300.00, a second prize of $200.00, and a third of $100.00. In addition, the winner of the first prize receives an expense-paid trip to the Annual Congress where the prize is presented at the banquet.

In 1970 the examination, organized by Brian Hlrd, University of Ottawa, was written by 69 students from 20 universities. The winners are :

W.R.Franklin University of Toronto First Prize

S.Pineault Université Laval Deuxieme Prix

P.Ting McGill University Third Prize.

Pictorial Facteria

A short course intended to familiarize science students with LITEROSCIENTICA MICRO-COSOMMES known to infect scientists.

The committee has been urging departments to persuade all students in honours physics to write the examination. The only university which responded to this appeal was Waterloo where 25 students wrote the examination. The top papers have been read independently by both Brian Hird and Robin Ollerhead, who will be organizing this examination in 1970-71.

ANNUAL REPORT 1969-70/RAPPORT ANNUEL 1969-70

The Annual Report for 1969-70 was dis-tributed to CAP members at the Annual Congress in Winnipeg. The report was subsequently dis-tributed to the members that did not attend the Annual Congress. This 48-page report is available free of charge upon request at the national office.

OFFICERS OF THE ASSOCIATION 1970-71 /

BUREAU DE DIRECTION 1970-71

The resignation of Dr. Albéric Boivin as Vice-President for reasons of continuing ill-ness was accepted by Council with great regret. Dr. Gilles Cloutier, of l'Institut de recherches de l'Hydro-Québec, and Dr. C. C. Costain of NRC, were subsequently appointed Vice-President and Honorary Secretary-Treasurer respectively for 1970-71. The list of the officers of the Association appears in the following pages of this issue, along with the lists of Division Executives and Committees for 1970-71.

COMMITTEE ON PHYSICS AND SOCIETY

A standing committee on Physics and Society was established at the annual general meeting. The objectives of this committee are to stimu-late discussion on those issues which are of national interest and to which a knowledge of physics is relevant. In particular, the committee will undertake to:

(1) find knowledgeable persons willing to write informal articles discussing a particular problem;

(2) publicize these articles by ensuring that they are submitted to relevant journals such as Physics in Canada, Science Forum, and to distribute such articles to the press and to government agencies as may be relevant ;

(3) arrange a session of invited speakers at the Annual Congress on topics of national interest;

(4) it was suggested by the Committee on the Role of the Annual Congress to arrange the publicity for items in the Congress of particular interest to the public.

HONORARY COUNCIL OF PAST PRESIDENTS

A recommendation from Council was adopted at the Annual General Meeting establishing an Honorary Advisory Council of Past Presidents of the Association. The role of this Council would be purely advisory; the Council would elect its own Chairman, and the representative of this Council on the CAP Executive would be the immediate Past President. This Council would meet annually at the time of the Annual Congress and draft recommendations to be brought to the attention of the Executive. The Executive could consult the Honorary Advisory Council at any time on important matters.

C A P STUDF ON PHYSICS RESEARCH IN THE

UNIVERSITIES

CAP will undertake a major study on Goals and Priorities for Research in Canadian Uni-versities under the support of Federal agencies. The study will be conducted by a Study Group under the responsibility of a Steering Com-mittee appointed by CAP.

The Steering Committee will consist of the elected officers of CAP, representatives from CAP Divisions, representatives of other sub-fields of physics and other representatives to insure geographical balance. The Study Group will consist of the Study Director, appointed by the Steering Committee, the Executive Director of CAP, and representatives from the principal subfields of physics appointed by the Study Director.

The study would start by analyzing the way in which financial support by NRC and other agencies was distributed by subfields in 1970-71; it would determine the rate of production of physicists by Canadian universities in 1970 and make projections to 1975; it would determine the number of physicists in each employment sector by subfield and academic level. The study will consider three options for the support of university research: rational growth of 20% per year ; status quo with 4% (for inflation increments per year; and reduced support of 5% per year. The study is supported by a $48,000. grant from NRC.

DIVISION OF NUCLEAR PHYSICS

The seventh annual Western Canadian Region-al Nuclear Physics Conference was held at the University of Saskatchewan, Saskatoon, February 20-21, 1970. The Conference was attended by 105 delegates representing the University of Saskatchewan (Saskatoon - 31 and Regina - 7), Manitoba (9), Winnipeg (2), Alberta (31), Calgary (1), British Columbia (20), and Victoria (4).

The Conference was highlighted by four invited papers. These were: "Pion Elastic Scattering Experiments using the S.R.E.L. 600 MeV Synchrocyclotron" by R. R. Johnson of U.B.C.; "The Statistical Model of the Compound Nucleus and the Determination of Spins from Particle Gamma Ray Correlations" by Dr. D. M. Sheppard of the University of Alberta; a theoretical paper by Dr. G. Papini of the Regina Campus of the University of Saskatchewan on the "Energy-


Momentum Form Factors of Nucléons and Light Nuclei"; and finally a very exciting paper by Dr. S. K. Sen from the University of Manitoba on "New Directions in Low Energy Electron Spectroscopy".

The invited talks were followed by 32 ten-minute contributions on current nuclear research being carried out at the Western universities. The Conference was a very well organized and successful affair, with the quality and pre-sentation of the papers being excellent. It was again clearly evident that these annual conferences provide a needed opportunity for nuclear physicists from Western Canada to meet and discuss their mutual problems. The eighth annual conference is scheduled to be held in February, 1971, at the University of Manitoba.

A Summer School on Intermediate Energy Nuclear Physics was held at the Banff School of Fine Arts from August 16-28, 1970. The School was sanctioned by the Canadian Association of Physicists and sponsored by N.R.C., NATO, A.E.C.L., and the University of Alberta. The holding of such a Summer School in Western Canada is motivated by the TRIUMF project, the 500 MeV variable energy, 100 )jA isochronous cyclotron being built on the University of British Columbia campus. It not only prepared Canadian scientists for the use of this unique facility, but also helped to make nuclear and particle physicists in Europe, Britain and the U.S.A. aware of the TRIUMF project and of the great interest and activity in intermediate energy physics in Western Canada. We can now look forward to a vigorous and fruitful scientific exchange in the future.

The School was limited to 100 participants. Of these, 60 - 70 were graduate students and post-doctorate fellows; the remaining number were comprised of faculty members of Canadian universities, several invited participants who are knowledgeable in the field of intermediate energy physics, and five main lecturers. The five featured lecturers and the subject matter with which they dealt are: T.E.O. Ericson (CERN), "Pionic Interactions"; M.H. Mcfarlane (Argonne), "Nuclear Structure Studies with Intermediate Energy Projectiles"; C. Wilkin (University of London), "Scattering Theory at Intermediate Energies"; H.Palevsky (Brookhaven), "Experi-ments at Intermediate Energies"; and J. E. Rothberg (University of Washington, "Muonic Physics".

SUMMER INSTITUTE ON "SOUR TERRESTRIAL

RELATIONSHIPS"

The University of Calgary Summer Institute on Solar Terrestrial Relationships, from June 2-5, 1970, was held on the Campus at Calgary, under the Chairmanship of Prof. D. Venkatesan. A little over 100 participants registered, with the majority of them coming from various Canadian universities interested in the general areas covered. There were also representatives from the National Research Council, Ottawa, the Atomic Energy of Canada, Ltd., Chalk River, and from a few institutions in the U.S.A.

The emphasis of the Summer Institute was to cover this wide area in a coherent and well integrated manner. The exchange of ideas and

discussion of problems both within the lecture periods and outside went a long way to make the Institute a success. There were 16 lectures, lasting 90 minutes each, given by four speakers.

The main topics of the Summer Institute were Solar Physics, Interplanetary Medium, Radiation Belts and Auroral Physics. Dr. C. DeJager, University of Utrecht, Utrecht, The Netherlands, lectured on Solar Physics, with emphasis on the Solar Outer Layers and their Electromagnetic Spectrum, the Morphology and theories of the origin of solar activity, the optical and high energy components of solar flares, the flare associated particle emission, flare theories and the acceleration of solar particles. An understanding of solar processes is the key to a better understanding of the interplanetary electromagnetic state and its control by the sun.

Dr. W. Ian Axford, University of California, La Jolla, Calif., dealt with the Solar Wind and its interaction with the interstellar med-ium. His discussion of the cosmic ray gradient stressed the importance of the solar contribut-ion, particularly at lower energies. His lectures also included the interaction of the solar wind with the planets, polar wind and the terrestrial helium Budget.

Dr. James A. Van Allen gave a review of the gross properties, dynamics and temporal varia-tions of the radiation belts of the earth, with particular emphasis on alpha particles and nuclei with Z - 3. He also covered solar electrons, protons, alpha particles and nuclei Z - 3. Another area covered by him was the soft x-rays from the sun,the quiet and slowly varying components, and the temperature and emission measures.

Dr. T. Neil Davis, Geophysical Institute, College, Alaska, provided an enormous collect-ion of auroral observations including obser-vations of all sky camera, observations from planes and movies of fast changing auroral patterns. He dealt with the general character-istics of particle precipitation, conjugate phenomena, the various classifications of sub-atoms .

The Summer Institute was supported by the National Research Council of Canada and the University of Calgary. Dr. C. J. Bland was the secretary.

EASTERN REGIONAL NUCLEAR PHYSICS CONFERENCE

Carleton University and the University of Ottawa were hosts to the Annual Eastern Regional Nuclear Physics Conference on April 11. About 75 physicists from CRNL, NRC, Laval, McGill, Queens, Ottawa, Carleton, Toronto, McMaster and Windsor attended. The sessions, morning and afternoon, were held at U. of 0. and Carleton, respectively.

The purpose of this Conference has been, traditionally, to hear reports on work being done by graduate students, presented by the students themselves. Thirteen contributed papers on theoretical and experimental topics were given, with three invited papers by N. de Takacsy (McGill), J. W. Knowles (CRNL), and M. K. Sundaresan (Carleton). The small size and air of informality which have been valued features of the Conference in the past


were still very much in evidence, with plenty of "rotunda discussions" going on throughout the day.

ANNUAL REPORT NO. 4 OF THE SCIENCE COUNCIL

OF CANADA

Both the style and content of this year's Annual Report from the Science Council have changed. A new section presents a personal report from the Chairman of the Council, Dr. 0. M. Solandt. Although the views expressed are in general accord with the thinking of the Council, this particular essay presents the current thinking of the Chairman himself and, therefore, not necessarily of all of the Council members.

Copies of Annual Report No. 4 are available on request.

In this report, Dr. Solandt touches briefly on the following list of topics:

Introspection in the Canadian Scientific Community :

Senate Committee on Science Policy. Cabinet Committee on Science Policy and Technology.

SCITEC. Science Writing. Federal Austerity.

Analogy with the United States.

Mechanisms : The Role of the Social Sciences. Technology Assessment. Social Indicators.

Improving the Structure of the Scientific Community:

Institutional Rigidities. The Structure of Federal Government Organization for Science and Technology.

The Fole of Professional Scoieties and Scientific Disciplines.

Scientific and Technical Manpower.

Current Problems: A Natural Environment. Multiple Resource Use. The Arctic. Urban Environment. Law and Law Enforcement. Road Safety. Pollution. An Environmental Council. Population.

Science and Non-competitive Services: Health Care. Education. Government.

Major Programs.

The time is approaching when TRIUMF will be in a position to consider individual proposals for experiments to commence at first beam date. The Operating Committee will, in the near future, recommend to the Board arrangements for reviewing proposals and for allocating beam time. It is planned to set up a Project Evaluation Committee and to ask for detailed proposals for specific experiments to be done in the initial period of operation, when e beam current will be low (< 1 yA). Such proposals should be submitted by the Fall of 1970.

Meanwhile, as an interim measure for the 1970-71 fiscal year, the Operating Committee has decided to allocate $15,000. to each of the member universities. This money is to be used for equipment development and experimental work directed towards experiments to be done in the first year of operation. The application of this money will be vested in the Operating Committee member at each of the four universit-ies.

The sound of heavy earth-moving equipment contributes a daily background to activity at the TRIUMF site as the hole for the substructure of the main building gets deeper. Driving cas-ing for the perimeter well-point system proved to be highly diverting as great fountains of water shot into the air. Despite appearances, TRIUMF didn't bring in a gusher. A contract for the construction of the concrete sub-structure in the amount of $2,171,881. was awarded to Commonwealth Construction Co.,Ltd., at a meeting of the University of British Columbia Board of Governors on May 5, 1970.

The Central Region Model is rapidly taking shape: the vacuum tank was delivered recently. This is the first major component to be installed on the site, and is the largest stainless steel vacuum tank ever fabricated in Western Canada.

INTERNATIONAL UNION OF PURE AND APPLIED PHYSICS

Book Reviews

AN INTRODUCTION TO THE PHENOMENOLOGICAL THEORY OF FERROELECTRICITY, by J. Grindlay. Pergamon Press, (1970), p.p. 225, Price: $10.50.

Twenty years ago ferroelectricity was an active field of materials research; new ferro-electrics were reported at a rate of one a month, and practical uses for their large piezoelectric and dielectric coefficients were developed. In computers and other important applications, how-ever, they failed to displace ferromagnetics, and interest waned a decade later. Recently, some of the old glamour has returned with the electro-optic revival, so that Prof. Grindlay's An Introduction to the Phenomenological Theory of Ferroelectricity has appeared at an opportune moment, a welcome reminder of past achievements.

The subject of this book is the thermodynamic theory of ferroelectricity. Elastic, thermal and dielectric properties are reviewed in the first chapter, using potassium dihydrogen phos-phate, rochelle salt and barium titanate, the big three of ferroelectricity, as examples. The linear time-dependent theory of an elastic di-electric is developed in Chapter 2, followed by derivations of the stability criteria and use-ful thermodynamic identities in Chapter 3. Perhaps the most original part of the book is Chapter 4, a general theory of non-linear elastic dielectrics, drawn principally from the author's research papers. In the last chapter, a polynomial equation of state is used to analyze the behaviour of uniaxial and multi-axial ferroelectric, concluding with Devonshire's theory for BaTi03.

The book provides a sound introduction to the subject, bringing together a number of scattered references, providing a standardized nomenclature, and supplying missing proofs. It Is intended for research workers and graduate

students, who will find it helpful, but not especially inspirational. A few contemporary examples would have livened the presentation considerably. Applications to optical proper-ties and multi-domain specimens are missing, as are antiferroelectrics, ferroelastics, and the Aizu classification. The strong point of the monograph is its emphasis on fundamentals and physical understanding.

To say that the book fills a gap in the literature is an understatement; it is the only extended account available. Prof. Grindlay's text will be a standard reference for some years to come.

COURS DE MECANIQUE THEORIQUE ET APPLIQUEE, TOME 2, par H. Beghin. Gauthier-Villars, (1969), Paris, p.p. 328. Cartonné $14.05.

Le titre complet de ce livre donne une bonne idée de son contenu: "Cours de mécanique théor-ique et appliquée à l'usage des ingénieurs et des étudiants des facultés, professé à l'Ecole Polytechnique". Le premier tome comprend l'exposé des principes de la mécanique (de la cinématique aus équations de Hamilton-Jacobi). Le second débute par la théorie du corps rigide et contient de nombreuses applications indust-rielles. La plus grande partie du tome 2 est consacrée à la mécanique des milieux continus: dynamique des fluides et résistance des matér-iaux. Comme exemples d'applications mentionnons la stabilité de le pomage d'un régulateur de vitesse, l'analyse d'une turbine à plusieurs etages de vitesse et a plusieurs étages de pression, le calcul d'un portique rigide doublement encastré, etc.

Ce cours fait appel à de solides connais-sances des mathématiques classiques et l'auteur ne craint pas d'utiliser des notions de géométrie différentielle (classique). A ce point de vue, ce livre se situe dans la tradition française et sera sans doute très utile aux étudiants des grandes écoles d'ingénieurs françaises. Pour les étudiants canadiens il a l'inconvénient d'exiger d'eux plus de mathématiques classiques qu'ils n'en possèdent habituellement. Si les difficultés mathématiques ne réussissent pas a éloigner de ce livre le lecteur éventuel, la présentation et le prix y arriveront sans doute. Car la présentation de ce livre est déplorable, la typographie du tome 2 est pitoyable et on y cherche en vain un index. De plus, le prix de ce cours est exorbitant. Comme l'auteur l'écrit dans sa préface, la compréhension du second tome exige une étude poussée du premier. Cependant, le premier tome (pp. 551, cartonné) coûte $23.40 ce qui fait un prix total beaucoup trop élevé pour ce que l'auteur (ou l'éditeur?) nous propose.

Peut-être les bibliothèques de nos ecoles d'ingénieurs devraient-elles s'en procurer une copie pour que leurs étudiants puissent con-templer le compagnonnage de Hamilton-Jacobi et des turbines hydrauliques !

ADVANCES IN CHEMICAL PHYSICS, Vol. XIV,(COR-RELATION EFFECTS IN ATOMS AND MOLECULES), by R. Lefebvre and C. Moser (editors). Inter-Science (1969), p.p. 545, $29.95 U.S.

Contents (Abridged Titles) Nesbet: Atomic Bethe-Goldstone Equations. Cizek: Cluster Expansion and Diagram Techniques. Judd: Effective Operators for Configurations of Equivalent Electrons. Kelly: Many-Body Diagram Techniques in Atoms. Jucys: Hartree-Fock Method in Multi-Configuration Approximation. Jucys and Kaminskas: Extended Method for Atomic Electrons. Brueckner: Correlation Energy of Electron Gas. Sinanoglu: Correlation in Atoms and Molecules. Lowdln: Correlation Problem and Possible Extensions of Independent-Particle Model. Grimaldi: Cor-relation Effects in Diatomic Molecules. Sandars: Linked Diagrams of Configuration Interactions in Open-Shell Atoms. Tolmachev: Field-Theoretic Perturbation Theory for Many-Electron Atoms, I and II.

In July, 1967, an Advanced Summer Institute on Correlation Effects in Atoms and Molecules was held in Frascati, Italy. Most of the lectures delivered at this Institute are con-tained in this volume. By providing an In-depth study of the techniques used and their application to the correlation problem, the book achieves its aim of giving researchers an up-to-date account of the subject. It should be pointed out, however, that this collection of articles is by no means an introductory text for the uninitiated. Quite the contrary, it is written for an advanced reader with consider-able experience in the area.

Although each paper is well written, there appears to have been little or no effort on the part of the authors, or the editors, to organize or co-ordinate the material, so as to blend the articles together. The reader is, therefore, given the impression that the subject is rather disjointed. Apart from this minor criticism, the volume represents a continuation of the fine tradition of the Advances in Chemical Physics series, though at a cost of $30. it is fast becoming far too expensive for the reader-ship to enjoy.

ADVANCES IN NUCLEAR PHYSICS, Vol. Ill, by M. Baranger and E. Vogt (editors). Plenum Press (1969), p.p. 480 + xiii. $22.50 U.S.

As the title suggests, this is the most recent in this series of review books. The volume is of interest primarily to nuclear physicists, but without distinction between the theoretical and experimental varieties.

My preferences among the articles are those of Aron Bernstein (Isoscalar Transition Rates in Nuclei from the a-a' Reaction - practically a monograph of 150 pages), and D. S. Koltun (Interaction of Pions with Nuclei - 120 pages). The latter is timely in view of the likelihood of soon having intense pion beams at TRIUMF and elsewhere. A. N. Mitra's article on the three body problem (65 pages) is restricted to

the work of his group using separable potentials, but may be the more readable as a result. B. Elbek and Per Olav Tj^m's article describing the Copenhagen work on single nucléon transfer reactions in deformed nuclei is likewise brief. The most difficult reading for me was the article by J. B. French, C. E. Halbert, J. B. McGrory and S. S. M. Wong describing the meth-ods developed at Rochester and Oak Ridge for attacking the shell model problem. It is clear that the new viewpoint espoused here is very powerful and should be grasped by all who wish to use the shell model, but being novel it is not easy to grasp.

Review books are not a recent invention, Reports on Progress in Physics having a long history and specialized series such as Annual Reviews of Nuclear Science being nearly twenty years old. There is however a steady increase in the number of new series appearing and in the degree of specialization. In this respect they are similar to collections of summer school lectures in offering a homogeneous selection of articles in a well-defined area of interest. The trend is to be welcomed. The continuing explosing of the physics literature has intensified the need for review articles surveying and summarizing the progress made. The development of commercial journals such as the present series encourages the writing of review articles by providing a small but interesting financial incentive to the author. The problem of distribution seems still to be better handled by the membership society jour-nals. Perhaps in time some sort of personal subscription scheme, such as that offered by Nuclear Physics, will be provided to make this series equally available to the individual. The present volume is well produced, but at a price that will see it mainly on library shelves.

CLASSICAL DYNAMICS OF MOTION, by E. J. Konopinski. W. H. Freeman and Co. (1969), p.p. xiii + 500. $15.00.

This book covers the elements of the dynamics of single particle systems (95 pages), many particle systems (247 pages), and continua (150 pages). The text is written at a level suitable for senior undergraduates, and all the standard topics - orbits, coupled oscil-lators, rigid body dynamics, Hamilton-Jacobi theory, the vibrating membrane, etc., - are discussed. Much of the mathematical apparatus required - vector and matrix algebra, Fourier series and transforms, etc., - is developed In the body of the text. The author has made a noteworthy attempt to emphasize the inter-connection of symmetry principles and con-servation laws In mechanical systems. While Konopinski offers a larger number of topics, Goldstein, in this reviewer's opinion, still provides the clearest exposition of mechanics available.

You might even let others know you didn't see theirs, and direct them to "the advertising editor, Physics in Canada , University of Water loo".

Thanks . p.s. You can still do it even if you didn't have a good time at the Congress.

Fine

when is a power supply not just a power supply? This is Kepco's JQE 100-10MHS Power Supply. It looks and is built much like the many hundreds of similar power supplies made by power supply companies. It will produce an adjustable voltage 0 - 1 0 0 V , with a 10-turn front panel control—will drive loads up to 10 amperes and is backed by a 5-year warranty.

That's where the resemblance to the product of other power supply companies stops. The JQE 100— 10MHS is made by Kepco, the power CONTROL company.

This means that you can manipulate its output to suit your purposes. You can use it as a J kW, d-c power ampli-fier and use as much of its 500,000 volts per volt d-c gain as you please. With that suffix "HS," the JQE will allow you to modulate its output with signals of your choice up to about 300 Hz for full 100V peak-to-peak swing. For 10V p-p modulation, you've got a 3 kHz bandwidth.

Would you like to sum several signals? Connect the JQE as a summing amplifier and use it to perform arithmetic operations.

Vary its feedback and input resistors digitally and you'll have a computer-controlled voltage source. We make an excellent digital programmer to work with our control-lable power supplies (the Kepco DPD, DPR, DPK Digital Programming System).

Typical 1/2 Rack Model

There are thirty-one (31) different JQE models in all sizes and output voltages from 0 - 6 to 0 - 1 5 0 volts up to 1125 watts . . . modules, too.

With a capacitor connected to its convenient feedback terminals, your JQE makes a dandy integrator.

Total involvement in tomorrow s science NEW SYSTEMS AND NEW PRODUCTS ARE NEWS! Thanks to our greatly expanded development effort in 1968, there is a lot of news from Simtec. For example: You have probably heard of our rugged, stable detectors for satellites — but have you heard of our complete N16 monitor systems for HWR safety? You know of our state-of-art linear amplifier, but did you know we now also offer the B-31, the best level-cut-gate-stretch-strobe unit on the market? You've probably used our superlative diffused-window E and A E detectors — but how about trying our rugged annular units? Or our 25mm deep units? And then again, did you know we have now introduced the "Scimitar" series of NIM-standard modules? They are the best low-cost modules you can buy. And we now make Op-Amps as well. Write and ask us about it all. Your letter will find us very attentive, very competent and very friendly. We'll find your letter most welcome.
