Onward March......MATHS IN LIFE

The definition of Mathematics from Britannica Concise encyclopedia is “Science of structure,order and relation that has evolved from counting, measuring and describing the shape ofobjects”. It deals with logical thinking and Quantitative calculations”. The literal meaning ofMathematics is “Things which can be counted”. Counting has vital role in our daily life. Justimagine that there were no mathematics at all, then how would it be possible for us to countdays, months, year and so on.

Mathematics is around us. Mathematical thinking is important for all the members of thesociety. It is the “Queen of Science”. It is in the workplace, business, finance and decisionmaking. Mathematics equips pupils with uniquely powerful ways to describe and analyze. Itsimportance in daily life cannot be questioned. It finds application in all the fields.

In fact common man finds it useful in his day to day life, whenever we manage money, travelto some places, meet new friends, pick up phones etc. Unintentionally in all these thingsmaths is involved.

Right from morning cooking of your mother - taking cup for measurements, buyingvegetables and other requirements, banking, savings and credit, counting, adding,subtracting, while building a house – the sq. feet and measurement, measurement whilebuying clothes. At the end of the day the expenses involved in items and the budget for thefamily.

Without !! the application of maths, no profession is complete.Let us for a change - imagine life without maths and counting what will happen?How would we count the time and calendar?How would we buy things?How would an engineer build a bridge or a building?How would a chemist prepare medicine?The entire life would come to a stand still.

No money, no counting , no transactions. Early man was involved in Barter system. Even thatwas a measurement for measurement. Maths is inbuilt in life. Infact life revolves aroundmathematics.

Dear students, Maths is wonderful. Learn to love it. You have well tried your hands inpuzzles, riddles, articles, calculations, algebra, geometry and so on. Kudoos!!!!!! to you ! Wecelebrate this year as MATHS YEAR in our school. Make the school vibrant with maths.

Mathematics is a subject that sharpens and strengthens the mind .Itcan be enjoyed if a person has some basic interest in it .Most of usthink that math’s is a difficult subject but when goes deep into it ,itbecomes better and interesting .But it is a subject that requiresdedication and persistent effort .It is the basic requirement for everyfield so one cannot ignore it .In fact mathematics is involved directlyor indirectly in whatever we do on a day to day basis.

Mathematics is considered as the mother of all sciences.

So let us all love mathematics .Imagine a world without mathematicsno scales ,no weights ,no heights, no rules life would b upside down.

Here’s a poem that tells about mathematics:

Log, angles, sine, alphas and moreFor every corner, there’s something to exploreRamanuja and Aryabhatta left us a lot to know ,Will there be an end??? I don’t think soAll the leaps and bounds of science has grown,

Wouldn’t have been possible if mathematics wasn’t sown.- BLOSSOM EDITORIAL BOARD.

THE WONDERS OF 10891089 IS A BEAUTIFUL NUMBER .Here is a trick toamuse your friends.• Take any 3 digit numbers whose digits are

different .• Reverse it.• Subtract the reversal number and the actual

number• Reverse the difference.• Now ,add the reversed difference and the

actual difference• Your answer will always be 1089 !

EXAMPLEThe number is 347723-347=396396 +693=1089

we know that 1089 is square .it is a square of 33.

NOW LOOK AT THIS33 X 33 = 1089333 X 333 = 1108893333 X 3333 = 1110888933333 X 33333 = 1111098889333333 X 333333 = 1111108888893333333 X 3333333 = 1111110888888933333333 X 33333333 = 1111111088888889

OBSERVE THE FOLLOWING1089 x 1 =10891089 x 2 =21781089 x 3 =3267……..………1089 x 9 =98011089 X 1 =1089 & 1089 X 9 =9801

9801 IS THE REVERSED FORM OF 1089 .THIS DOES NOTHAPPEN WITH MANY MULTIPLICATIVE TABLES DOESIT?

If you have observed the above series, you wouldhave found out the following:

! The first digit (the digit in thousand’s place )arebetween 1 and 9

! The second digit (the digit in the hundred’s place)are between 0 to 8

! The third digit (the digit in ten’s place )arebetween 0 to 8

! The fourth digit (the digit in one’s place)arebetween 1 to 9

SRI SOWMYA .G, VIII-E

Mathematics has been considered the oldest ofsciences. Our country has given mathematicalgeniuses like Aryabhatta, Srinivasa Ramanujamand others to the world and mankind.

In the present day context, mathematical scienceis accepted as an integral part of technologicalprocess. Recent mathematical developmentsprovide a culture of logical thinking, explainsmany complicated processes and secures theessence of technological development. Startingwith Newton, mathematics became a tool in theexplanation of Physics as we know it today.

The following are recent examples where the useof mathematics has proved crucial in science andtechnology:• Integral geometry has provided a

• The creation of modern fiber optic cableswould not be possible without the discoveryof special solutions of linear equationscalled solitious.

• Mathematicians are involved in improvingthe understanding of fundamental problemsin genomics research, cell signaling, systemphysiology, infection and immunity,developmental biology, the spreading ofdiseases and ecology.

In a nutshell, advancements in mathematics havebeen instrumental in taking science andtechnology o reach great heights.

ADVANCEMENT OF MATHS IN ARCHITECTURE In the 21st century architecture is about creating the built environment. Architecture’s primary functionsand elements to be “strength” , “utility” and “beauty”.

How does math help architecture design and build something that encompasses strength, utility andbeauty?

Historically, math and architecture have gone hand in hand. Even now maths is important in architecturemathematicians were architects and architects were mathematicians, think of the pyramids, ancienttemples, irrigation systems, and greek and roman architecture we are astounded by today.

An obvious way math correlates directly with architecture is in the “strength”. Angles must be precise, walllength, and roof measurements must all be taken and be made perfect so as to ensure durability and longlasting structure integrity. Furthermore, math involving partial derivatives, multiple integrals, andsystems of differential equations are used in the computer software engineered for architects.

“Beauty” is another essential element of architecture which is achieved through math in many cases.Adding ornamental design to buildings can enhance its beauty. Often these designs include symmetry,geometric shapes, fractals and other wall paper type patterns which derive from mathematics.

So architecture is made possible through mathematics alone. Without a basic understanding of math, onemay never live in a strong, purposeful, and beautiful building.

APPLICATION OF MATHEMATICS INSCIENCE AND TECHNOLOGY

Mathematics is the foundation of all sciences. Science and technologyis based on the application of mathematics in it. For example, appliedmathematics in science and technology are as follows:• Scientific notation in space.• Base “2” binary number etc.

The earth, that we live in and the planet which is one among the other8 planets revolving around the sun also has various measurementslike distance from sun, distance from other distance from sun,distance from other planets etc. which are based only onmathematics.

Mathematics is involved in the works we do in every nook and cornerof the world.

Mathematics is used in our everyday life and life withoutmathematics is like a tree without leaves and fruits. Greatmathematicians like ramanujam have contributed a lot towardsmathematics and we should also follow their way.

WONDERS OF MATHEMATICS• This particular essay on the wonders ofmathematics came about in party by a readerpointing out that

9 divided by 9 is equal to 1 and not 0.99999…

The latter of course, was a logic extension of thetable previously provided in the treatise on ninesand as duplicated here.

Numbers /7 /9

1 0.142857…. 0.111111….

2 0.2857 0.22222….

3 0.571428 0.33333….

4 0.57142857…. 0.44444….

5 0.7142857…. 0.55555….

6 0.85714…. 0.66666….

7 1.00000…. 0.77777….

8 1.142857…. 0.88888….

9 1.285714 0.99999….

• The precise mathematical proof consists ofassuming first a no. n which is defined by

N=0.99999….

• If we now multiply both sides of the equationby 10. We obtain

10N=9.99999….

Now subtracting N from each side of the equationwe obtain

10N-N=9.99999…. -N=9.99999….-0.99999….i.e. 9N=9 N=1=0.99999….

Thus it is conclusively proved.

MATHEMATICALNEUROSCIENCE

Mathematical neuroscience is an area ofneuroscience where the use of mathematics iskey in elucidating the fundamental mechanismresponsible for experimentally observedbehaviour. In illustration of this point, it is worthmentioning some success, perhaps foremostbeing the work of Alan Hodgkin and AndrewHuxley on a mathematical model of the actionpotential. The conceptual idea behind this work isthat all membranes behave like electrical circuits,and that the flow of ionic current in their circuitmodel is gated by state-dependent conductance.The great insight of Hodgkin and Huxley was toexpress the dynamics of these gating variables(representing membrane channels) using themathematical language of nonlinear ODES.Together with Sir John Eccles, the pair receivedthe Nobel prize in Physiology or medicine in 1963“for their discoveries concerning the ionicmechanisms involved in excitation and inhibitionin the peripheral and central portions of the nervecell membrane”. In essence their mathematicalwork describes a model of excitable tissue thatremains the basis of pretty much all conductancebased neural models to date.

SUPER JUGGLERYThere are many magical games with the numbers1 to 9,But most fantastic is this.

Write the numbers from 1 to 9 each only once inthree rows such that the sum of the first two rowsis equal to the third row

Multiples Rows:-

In the following examples, The second row isdouble of the first row. Hence, the third row isthrice of the first row

192+384=576219+438=657273+546=819327+654=981

Repetitions Avoided:-

By interchanging the corresponding numbers inthe first two rows the same is obtained in 8different ways, as shown below:-

182+394=576184+392=576192+384=576194+382=576382+194=576384+192=576392+184=576394+198=576

Peculiar pair:-

There are some peculiar pairs of solutions. Thefirst rows in both is the same. In the second row,one is the reverse of the second row of the other.Similarly, third row are reversed.

152+487=639 ! 152+784=936162+387=549 ! 162+783=945

MATHEMATICS IN ANIMATIONMathematics is used in many areas which includeanimation, architecture, graphics and in otherfields.

In the 21st century, animation is hand in hand withmathematics. The algebra and trigonometry isbeing put to good use in animation industry.Without mathematics, we wouldn’t have visuallyrich environments and characters. Earliermathematics show simple, hard, plastic toys. Now,advancements in mathematics help to make morehuman-like characters. Animation is the newadvancement in geometry.

Trigonometry helps to move and rotate characters.Algebra creates the special effects that shine andCalculus helps light up a screen. Geometryanimation is the most complex and requireschanging the geometric elements of a scenedynamically.

Thus all the characters we see in animation iscreated with the help of Mathematics.

Forensic science is a branch of science thatinvolves investigation of crime sciences. Allscience uses mathematical concepts. Forensicscientists equip themselves in all concepts ofmathematics, Trigonometry, Measurements,proportions etc., are mainly used by forensicscientists for crime detection. Mathematics liesbehind expert conclusions on a hundred forensicmatters from fingerprints to DNA. Statistics can bea precious tool in identifying the patterns behindconfusing or misleading phenomena. Anotherarea which involves subtle mathematics is DNAidentification. In some cases the crime sceneevidences are tiny, mixed on degraded. In thesecases identification can be made only with certainprobability, and is essential to be able to interpretthe probability correctly. Their data help theforensic scientists to perform calculations anddetermine facts of a crime.

MEASUREMENTS

Taking precise measurements is crucial forensicscience. Knowing the exact length of shoe canhelp to rule out crime suspects whose shoe sizescan are wrong .Investigators spend a great deal oftime measuring distance temperature ,volumeand other aspects of evidence to get the numberscorrect .

PROPORTIONS

Forensic scientists also use proportions for theiranalysis .If a human leg is discovered in anunmarked grave forensic scientists usemathematical equations to determine what

MATHEMATICS IN FORENSIC SCIENCEproportion or percentage of a person’s overallheight the leg bone would be .They candetermine how tall the person was a whether itwas a child or a adult .

TRIGNOMETRY

Trigonometry, the study of triangles is anotheruse of mathematics In forensic science. Bloodsplatter analysis use trigonometry in their studyof how

Blood from a human injury splatters on a wall orother surface .They draw lines from victims’bodies to blood splatter ,then use angles anddistances to calculate the third point of thetriangle ;the person who stuck the victim ,wherethe attacker was standing and how hard he musthave hit the victim.

PROBABILITIES

Probabilities is a measurement of the likelihoodthat a specific event will occur under certainconditions. Forensic scientists often useprobabilities to explain how likely it is that theirfindings are correct. A forensic biologist who hascompared a suspect’s DNA to DNA from a fluidsample found at the crime scene will tell the jurythe probability that the DNA samples are from thesame person. Probability that the DNA samplesdid not come from the same person is 1 in 100billion.

Likewise mathematics is used in differentspheres of life.

I. (M) A parabola has a maximumvalue when it has a negativecoefficient for the x2 term

II. (A) Achilles and the tortoise areone of the paradoxes of greekphilosopher, Zeno. It is veryimportant as It introduces theconcept of limit. The paradox statesthat Achilles can run ten timesfaster than a tortoise. If the tortoiseis given a 100m start, and whenAchilles runs that 100m, tortoisewill be at 110m. Thus, the tortoisewill be one tenth ahead.

III. (T) Tropology is a branch ofmathematics concerned withrelationship rather thanmeasurement. Ex: interior-exterior

IV. (H) Hyperbola is a group of curvesthat are constrained between fixedlines called asymptotes

V. (S) Standard deviation ofpopulation is the measure ofspread of data about a mean

GOLDEN RATIOThe golden ratio is also known as GOLDENSECTION (or) GOLDEN MEAN.

Euclid’s gave the definition for the golden ratio:-

A straight line is said to have been cut in “extremeand mean ratio” when as the whole line is to thegreater segment so is the greater to the less.

The symbolic representation of golden ration is ð(phi).

The reciprocal of phi is ö (upper case phi). Manyyears ago artists have proposed their works toapproximate the golden ratio, especially in theform of golden rectangle.

GOLDEN RECTANGLE REPRESENTATION IN GOLDENRATIO:-

The ratio of the longer side to the shorter side isthe golden ratio

a+blonger side=ashorter side=b

Here is the golden rectangle with longer side aand shorter side b when placed adjacent to asquare with side a, will produce similar goldenrectangle with longer side a + b and shorter side a.

" The people in America celebrate a festivalcalled “pie-day” on 14th march every year. Piewas calculated to 100 places by Ramanujam.

" It was not ‘the great Srinivas Ramanujam’ asmany people think to have found zero.Actually, it was Brahmagupta, an Indianancient great had found the number.Ramanujam proved only that zero had values.

" The people in ancient India, didn’t usesymbols like +,-,×,÷ etc,. Instead they hadtheir own ways of expressing them. Suchsymbols are used in the vedic mathematics.They used ‘.’ For addition, ‘..’ for subtractionand so on.

" The great mathematician Ramanujam said,“he used to meditate instead of calculatingproblems to get their answers. The answerwould appear in his vision by symbol in hisvision by symbol of lights and colours.

" Is 8+8=91? Many people accept because whenupside down, it appears so.

" To find a number, thought of by someone (in 2digits), we can find the number by getting theresult of multiplying by 2, adding by 2,multiplying by 5, adding by 5, multiplying by10, adding by 10. Then subtract 1 from left-hand side number.

Example:-

If we think of 5,

5 x 2 = 10; 10 + 2 = 12; 12 x 5 = 60; 60 + 5 = 65;65 x 10 = 650; 650 + 10 = 660; 660 # 6 – 1 = 5

Similarly, we can find any number. Interestingly,the right side is always 60.

MATHEMATICS AS A GATEAND KEY TO SCIENCE

our world is so much better because of thescience and maths. They both are alwaysconnected. Life without science and maths isunimaginable. It is terrible. Everywhere in theworld are always surrounded and carried away byscience and maths. Every small calculations inscience is of maths.

These are some of the math-science relatedinventions:-

" Abacus " Algebra" Calculus " Dynamite" Number zero " Complexity theory" Aircraft designing " Nanotechnology" DNA structure " Shape optimizationetc..

Everything, right from the invention of wheel tillthe invention of today is based on science andmaths. It acts as a backbone to the modernscience.

For example,

1. How difficult it would be for an experimenterto interpret his results without the aid ofmathematics.

2. Whatever It may be, from weathertemperature till the rankings of the sports starinvolves some mathematical calculation andtechniques.

Just like the crests on the heads of the peacocksand like the gems on the hoods of cobra,mathematics is on the top of all sciences.Mathematics is the cheapest science. Unlikechemistry and physics, it does not need aexpensive equipment and just needs a pencil andpaper. In most sciences, one generation tearsdown what another has built and established. Butin maths it gives a new story to the old structure.

MATHEMATICS IN ARCHITECTUREBenjamin Peirce called mathematics “the science that draws necessary conclusions”. Mathematics is usedthrough out the world and it is an essential in many fields such as engineering, medicine. Mathematicsengage with applied and pure mathematics. Aristotle defined mathematics as “the science of quantity”.

Mathematics place a major role in architecture. The Indian temples are the most famous for theirarchitecture. The structural harmony is a very much important aspect of building. It is believed thatmeticulously well constructed temple radiates peace and joy and ensures the wealth of the people. Tobuild a temple, structural harmony, proportionality, symmetry are the major factors without which thebuilding wouldn’t have any principle design. The Vastushastra render beauty to the temple. The lighting ofspaces inside the temple is orchestrated such that the maximum light enters the Garbhagraha only on thedeity: Meenakshi temple, Madurai Vijaya Vittala temple of Hampi, Vijayanagar ehich has the musicalpillars which when struck at aprecise part produces the seven swaras. The standard unit of measurementis “anu” as particle. This is used so as to have a proper carving of minute and delicate things, one such thingis Hoysala images.

As Albert Einstein said, “as far as the laws of mathematics refer to reality, they are not certain and as far asthey are certain, they do not refer to reality”.

MATHEMATICS IN AVIATION SCIENCEMathematics is woven into many areas ofeveryday life. It is used widely in many fields. Inevery turn we take we see mathematics.

One of the many applications of appliedmathematics is in the field of aviation science.Aviation and mathematics are entwined. Manyexamples of mathematics being used in aviationscience are available. Tolerances in turbineengine components which need to be measuredin ten-thousandth of an inch make use ofalgebraic formulae and matrices. The use offractions and proportions are required to performsheet metal repair on aircraft structures. Ratiostoo have widespread applications in aircraftmaintenance. Compensation ratio, aspect ratio,air fuel ratio and many such important factors inan aircraft is calculated by using the principles ofratio and proportion. The calculation of the totaltime it takes for an aircraft to reach its destinationfrom its initial place of take off with the windresistance involves intense mathematicalcalculations in trigonometry and vector algebra.Trigonometry is essential in determining theroute in which the aircraft travels with the force ofthe wind added to its course.

In practical maneuvering of the aircraft, pilots use

“rule of thumb” and printed tables based onvarious mathematical concepts to chart thecourse to reach the destination and to estimatethe performance rate of the engine.

Not only in aviation science, mathematics is alsoused in many other important fields which affectthe economy of the country. Mathematics can alsobe termed as a “set of tools” which comes handyin every walk of our life.

Chess, as many people on earth know it as a gamewhich is dominated by the intellectual beings onearth. But a few see this game as a teacher whotrains her apprentice to face all challenges/threats/and whatever we face in life in allpossible ways and means. What if I said that chesshas a mathematical understanding? A theoryinvented to know all possible moves and logicalpositions possible yet ?. Many of us do not knowthat chess could be understood mathematicallyi.e. ripped apart .

“There are 5,362 possible positions (White’ssecond ply move) or 8,902 total positions aftertwo ply moves each. There are 71,852possible positions or 197,742 total positions afterfour moves. There are 809,896 possible positionsor 4,897,256 total positions after 5 moves. Thereare 9,132,484 total positions after 6 moves.

MATHEMATICAL CHEMISTRY:

Mathematical chemistry is the area of researchengaged in novel applications of mathematics tochemistry; it concerns itself principally with themathematical modeling of chemicalphenomena.[1] Mathematical chemistry has alsosometimes been called computer chemistry, butshould not be confused with computationalchemistry.

Major areas of research in mathematicalchemistry include chemical graph theory, whichdeals with topology such as the mathematicalstudy of isomerism and the development oftopological descriptors or indices which findapplication in quantitative structure-propertyrelationships; and chemical aspects of grouptheory, which finds applications instereochemistry and quantum chemistry.

The history of the approach may be traced backinto 19th century. Georg Helm published atreatise titled "The Principles of MathematicalChemistry: The Energetics of ChemicalPhenomena" in 1894.[2] Some of the morecontemporary periodical publicationsspecializing in the field are MATCHCommunications in Mathematical and inComputer Chemistry, first published in 1975, andthe Journal of Mathematical Chemistry, firstpublished in 1987.

The basic models for mathematical chemistry aremolecular graph and topological index.

In 2005 the International Academy ofMathematical Chemistry (IAMC) was founded in

APPLICATIONS OF MATHEMATICS IN SCIENCE AND TECHNOLOGYDubrovnik (Croatia) by Milan Randic. TheAcademy Members are 82 (2009) from all over theworld, comprising six scientists awarded withNobel Prize.

MATHEMATICAL PHYSICS:

Mathematical physics refers to development ofmathematical methods for application toproblems in physics. The Journal of MathematicalPhysics defines the field as: "the application ofmathematics to problems in physics and thedevelopment of mathematical methods suitablefor such applications and for the formulation ofphysical theories".

MATHEMATICAL ARCHITECTURE:

Mathematics and architecture are related.Architects intentionally or accidentally usemathematical proportions to shape buildings.

In ancient Greece, the golden ratio may havebeen used to lay out some buildings. In Islamicarchitecture, geometrical shapes and tilingpatterns are used. The pyramids of ancient Egypthave mathematical proportions including thegolden ratio, for whatever reason. Hindu templesmay have been laid out using the mathematics ofastrology; they also have a fractal-like structurewhere parts resemble the whole.

In Renaissance architecture, symmetry andmathematical proportion were deliberatelyemphasized.

In the twentieth century, styles such as modernarchitecture and Deconstructivism exploreddifferent geometries to achieve desired effects.

ENGINEERING MATHEMATICS:

Engineering mathematics is a branch of appliedmathematics that concerns itself withmathematical methods and techniques that aretypically used in engineering and industry. Alongwith fields like engineering physics andengineering geology (both of which may belongin the wider category engineering science),engineering mathematics is an interdisciplinarysubject motivated by engineers' needs both forpractical, theoretical and other considerationsout with their specialization, and to deal withconstraints to be effective in their work.

Historically, engineering mathematics consistedprincipally of applied analysis, most notably:differential equations; real and complex analysis(including vector and tensor analysis);approximation theory (broadly construed, toinclude asymptotic, variational, and perturbativemethods, representations, numerical analysis);Fourier analysis; potential theory; as well aslinear algebra and applied probability, outside ofanalysis. These areas of mathematics wereintimately tied to the development of Newtonianphysics, and the mathematical physics of thatperiod. This history left a legacy as well: until theearly 20th century subjects such as classicalmechanics were often taught in appliedmathematics departments at Americanuniversities, and fluid mechanics may still betaught in (applied) mathematics as well asengineering departments.[1]

The success of modern numerical computermethods and software has led to the emergenceof computational mathematics, computationalscience, and computational engineering ,whichoccasionally use high-performance computing forthe simulation of phenomena and the solution ofproblems in the sciences and engineering. Theseare often considered interdisciplinary fields, butare also of interest to engineering mathematics.

THE DEVIANT,MR. MATHEMATICAL

Mr. Mathematical was to leave for japan,His new attire all spick and span.But, there was one thing left to do,His packing! of all the things left to be due,He couldn't choose between circle and cubepacking,He decided to go with hexagonal racking.

Mr. Mathematical's flight was set to leave at 8o'clock,At 7:15 sharp, he turned his apartment lock,At 7:45, on his comfy leather seat sat,Found himself falling asleep at 45o lat (latitude).He knew that lift was what kept an aircraft in theair,Though he had no idea what aviation dynamicswere .

Mr. Mathematical went to Mount. Fiji, thefollowing day,He was delirious to have come here on thesummer of May.No words could explain his rapture,He was sure, this was a sight his camera wouldsurely capture.A perfect click was what he wanted,All the right angles and measurement his pictureflaunted.

Mr. Mathematical paid a visit to the Tokyo Sights,He watched open-mouthed at the cities glowinglights.At Shinjuku, Tokyo's most famous structure,He learned quite a few about the golden ratioarchitecture.

Alas! Mr. Mathematical's vacation was soon to beover,He instantly began to feel his spirits lower.Math wanted to learn and forever remember ahaiku song,That was five syllable and 12 scale ratios long.

MATHEMATICAL DIAGRAMSAny concepts in mathematics can be representedby diagrams. Here are three different diagrams;

Argand diagram:-

It is used to represent the complex number. It wasnamed after Jean-Robert Argand. It is used to plotthe position of poles and zeros of a function in acomplex plain.

Butterfly diagrams:-

It shows the data flow diagram connecting input x(left) to the output y(right) that depend on them.It resembles a butterfly. Hence it name butterflydiagram.

Young diagrams:-

It is a finite collection of boxes or cells arranged inleft- justified rows. Rows size weakly decreases.It was introduced by Alfert young, mathematicianat Cambridge University in 1900. It was applied tothe study of symmetric group by GeorgeFerbinous.

FUZZY LOGICAND THE TECH-WORLD!!!

Imagine you are a four year old, who doesn’tknow numbers yet your mother gives yourbrother or sister two extra candies. You knowwhat will happen! Total havoc , cries and fights!But how are you able to identify that the quantityof candies your sibling received is more than youyourself did?

Well, numbers live inside us, just like words andmusic and this is called NUMBER SENSE which isfamily to LOGIC.

YES, MATHEMATICAL LOGIC- The mother of thetech-world we live in today! The ability to reasonand assess something adhering strict principles ofvalidity is called logic. It has existed ever since thetime of Aristotle, was the father of logic . over theperiod, its applications developed giving way tofuzzy logic.

Fuzzy logic is a problem solving control systemmethodology that lends itself to implementationin computer systems, ranging from simple, smallmicro-controllers to large networked multichannel PC or workstation –based dataacquisition and control systems. It can beimplemented in hardware, software or acombination of both.

It is conceived by lotfi-zadeh, a professor at theuniversity of California at Berkley. It provides asimple way to arrive at a definite conclusionbased upon even vague or missing inputinformation. Its approach to control problemsmimics how a person would make decisions, onlymuch faster!!

It incorporates a simple rule-based IF X AND ETHEN Z approach to solve control problem. It isalso a very robust and forgiving of operator anddata input and often works when firstimplemented with little or no tuning.

INDIAN MATHEMATICSIndian mathematics emerged in the Indiansubcontinent in 1200 BC .In the classicalperiod of mathematics, importantcontributions were made by scholars like• Aryabhata • Brahmagupta • BhaskaraII

The decimal number system in use todaywas first recorded in the Indianmathematics. Indian mathematicians madeearly contribution to the study of theconcept of zero as a number, negativenumber, algebra and arithmetic. Inaddition, trigonometry was furtheradvanced in India and in particular, themodern definitions of sine and cosine weredeveloped here. These mathematicalconcepts form the foundations for manyareas of mathematics.

INFINITY –“A BEAUTY” - ∞…its not big…its not huge..its not extremely large…its not tremendously enormous…its ENDLESS!

Infinity is a term used in mathematics and in allspheres of life. It is a wonderful word inmathematics that defines the indefinite.Everything ends at infinity, our expectations,desires which are endless. Basically it is an idea ofsomething which is never ending and endless.Sometimes people say it goes on and on whichsounds like it growing somehow, infinity does notdo anything it just is. It is not a real number, it is anidea. It is an idea of something that has no end andcannot be measured.

Yes! It is actually simpler than things which dohave an end, because if something has an end youhave to define where that end is.
