The Cavendish Laboratory 2008Current Research and Future Development

The Department of Physics

The Cavendish Laboratory

• The policy of the Department is to maintain a very powerful core of fundamental physics in all its diversity supported by theory.

• The Department encourages applied and collaborative research in response to the evolution of the basic disciplines and the interests of the staff.

• Physics is what Physicists do.

• Physics is extensive.

• Among the new developments are initiatives in the Physics of Biology, Medicine and the Life Sciences.

In the 1953, Francis Crick and James Watson completed their studies of the double helix structure of DNA. These discoveries led to the foundation of the Laboratory for Molecular Biology, a separate organisation funded by the Medical Research Council.

Physics is Extensive

Physics of Medicine

• Physics of Medicine is a new initiative led by the Cavendish.

• It will create an environment where researchers can freely mix, discuss and share ideas at the interface of the physical sciences, technology, life sciences and clinical research.

• A new building is being constructed.

• Phase One will officially open in Dec 2008.

• Priority project is the construction of Phase Two.

• Practical Application of Physics Research for the Benefit of Society

• The Intellectual Underpinning of Physics and all Cognate Sciences

• The Development of Individuals with the Ability to Relate Phenomena to Mathematical Structures in a Non-trivial Way

• Physics for Its Own Sake – Insights into the Nature of Our Physical Universe

Development

• Physics is a living and dynamic discipline, which continues to expand in intellectual depth and breadth.

• Particularly significant are the many cross-linkages with other departments, notably the physics of biology, medicine and the life sciences.

• These ground-breaking developments require new investment in infrastructure.

Development

• The University has recognised that it is essential to rebuild the Laboratory to match the new requirements of the research and teaching programmes. Specifically:

• The present buildings, constructed in 1974, are no longer appropriate for the current programme or, in light of new interdisciplinary collaborations and new investigative techniques, for the future direction of research at the Cavendish.

• The provision of state-of-the-art laboratories, offices and supporting infrastructure, including scientific computing, with all the advantages of modern design, will enable the Cavendish to maintain and enhance its contribution to physics at the international level.

• The reconstruction of the Laboratory will complement the University's ambitious plans for a major contemporary science complex on the West Cambridge site.

Outreach

• Educational Outreach to the broader community, particularly young people, is an essential part of the work of the Laboratory.

• The Educational Outreach Office has the prime objective of stimulating interest in physics amongst 11-19 year-olds.

• Physics at Work

• The flagship event organised by the Cavendish is the Physics at Work exhibition.

• Over 2000 young people visit the Laboratory over a three-day period.

Outreach

• Working with Schools• Educating the next generation of

physicists is regarded as an important responsibility.

• Senior Physics Challenge• A major "schools physics

development programme” and "university access initiative" .

• Cavendish Physics Centre• Envisioned well-equipped facilities

to demonstrate the scope of physics.
