Usefulness of Shrinivasa Ramanujan's Work in Mathematics

 Ramanujan’s work includes Prime Number, Hyper Geometric Series, Modular function, Elliptical functions, Mock theta function, Magic square, Number theory and some geometry. Many of his results have been used in subject like particle physics, statistical mechanics, computer science, cryptography and space travel. Let me simplify the same for the young readers.

1. His work on Riemann zeta function have been applied on the theory of pyrometry aimed at making better blast furnaces.
2. His result has been used to find the better approximate value of pi.

In 1989, Chudnovsky brothers computed π to over 1 billion decimal places on a supercomputer using a variation of Ramanujan’s infinite series of π.

3. Crystallographer S. Ramaseshan has shown how Ramanujan’s partition theory sheds light on polymer technology. his work on partition has found useful in splicing telephone cables, whose shorter subunits of varying length, again add up to make a whole.

His work on partition theory has applications in a number of areas including particle physics (particularly quantum field theory) and probability.

4. Ramanujan published his paper titled “On certain arithmetical functions” in the year 1916 that investigated the properties of Fourier coefficients of modular forms. He also developed three conjectures on it and his first two conjectures helped develop the Hecke theory, which was formulated 20 years after his paper, in 1936, by German mathematician Erich Hecke.

His third conjecture played a pivotal role in the development of Langlands program in 1970 under Robert Langlands. This program aims to combine two mathematical branches Representation theory and algebraic number theory.

5. Famous Physicist Prof A K Sen has used Ramanujan’s Modular equation to analyze the concept of String theory.

6. The famous taxi cab number and the elliptical curve y^2=x^3+ ax + b that Ramanujan worked on, has a great impact on K3 surface which plays pivotal role in Quantum physics. Calabi- Yau Manifold is an example of K3 surface.

8. Ramanujan’ work on Theta Function is used to determine the critical dimensions in Bosonic string theory, superstring theory and M-theory.

9. Mathematician Ken Ono says that Ramanujan’s work on Mock Modular form is now used to compute the entropy, or level of disorder, of black holes.

10. Even the Cloud Computing we use is based on Ramanujan’s result.

Convergent vs Divergent Thinking - K Bhanumoorthy

 

Thinking Mathematically Part - 3

Convergent vs Divergent Thinking

 “It is clear that the chief end of mathematical study must be to make the students think.”

                 ----- John Wesley Young, American mathematician.

 

Courtesy :- Convergent Vs. Divergent Thinking: Know the Real Difference (pinterest.com)

                                                                   Convergent Thinking: 

Converge means coming closer together/come to/ towards the same point, with reference to psychological aspects mean to follow only on well-established facts. In biological aspects means evolutionary convergence. In mathematical terms, given a series approaching a definite limit in case a more number of terms are added. There are logarithmic series, exponential series geometric series, other kind of series. All human beings use convergent thinking in some process of our daily life.

 An example as x tends to infinity implies 1 / x tends to zero (0).

Y= 1 /x, converges to zero as x increases, the limiting value of y is zero since y can be made as small as one thinks of. The line y = 0 (the x axis is known as asymptote of the function.

Let me give another example. Observe the sequence 128,64, 32, 16, 8,4, 2,1, 0.5,0.25. ---

Every number is half (1/2) of the previous number, the limiting value is zero (0), in other words come closer to zero.

Observe the sequence, 3,6,12,24, 48,96, 192, 384, 768, 1536, ----, every number is double the previous number. In this case the limit tending to infinite.

 Convergent thinking helps an individual or in other terms allowing to connect different elements in a question. It is nothing but choosing a correct/ opt method, to solve the problem. It’s a matter of befitting/ correct strategies.

Divergent thinking: 

Divergent means be different from, varying/ dissimilar/ unlike/ unalike. If we think on psychologically, it is variety of thoughts, assumption more in numbers. Mathematically to say increase indefinitely, moving away from normal path. It’s a process /method used to generate creative ideas, finding out many possible solutions Divergent thinking had been coined by Mr. P Guilford in 1956. 

Christopher Danielson had written a number of books where he mentioned   about divergent thinking. Divergent thinking helps in self-entrepreneurs, and also the people who lead the organizations. Creative thinking helps divergent thinking. Open ended questions, brain storming questions generate divergent thinking. It’s a journey of thinking, how one ‘s mind works. In brief I would say thinking outside the box. In mathematics, activities promote divergent thinking. The ideas that flow through one’s mind are in flexible way and displayed. 

Different age people think /respond in different ways. Divergent questions, have no specific answers, also generate divergent thinking and encourage students to think more. Brain storming sessions in a class shall develop divergent thinking skills. Even this can be tried out, a topic may be given to students, may be asked to submit their ideas, children’s creative play also develop divergent thinking. There is a playful approach in this sort of questions. One who thinks what to count is matter of thinking, rather how does one view.

An example: we know 1+1 =2.  Suppose I write 1+1 = 6, how,  

In what way it is true.  1car + 1 scooter = 6 wheels.

1 goat + 1 man = 6 legs. In the same manner we can think of plenty, yes, a sort of divergent thinking.

Another example: given 123456789. = 100. One can use any fundamental operations of arithmetic (+, -.X, ÷) How then, the answer is given below.

1+2+3+4+5+6+7+8x9 = 100.

IN 1887, Emmit invented folding bike. There are quite number of things, to use the optimum space in aa house/any place, many, like, folding chairs folding dining tables, folding cots, folding cup-boards, folding cycles, plenty of things so to say. All these things emerged out, on account of divergent thinking. Could I say! .

To conclude human beings are blessed with thinking skills, one among the 6 senses. Let us utilize them with positive thinking  in a proper way, utilize them for the benefit of humanity and make this beautiful land of earth, sustain peace, happiness prevail in the whole universe.

A quote from Lao Tzu.

“Kindness in words creates confidence. Kindness in thinking creates profoundness. Kindness in giving creates love.”

 

Thinking Mathematically Part - 2 By K Bhanumoorthy

   Thinking Mathematically Part - II

 “No problem can be solved until it is reduced to some simple form. The changing of a vague difficulty into a specific, concrete form is a very essential element in thinking.” ----    J.P Morgan

 Concrete Thinking: The word concrete means definite/ real/ genuine/ factual/substantial/ solid/ tangible so on. It is centered on one’s observations, feeling, and experiences felt in the present non-abstract concepts. It is part of leaning process, possible be developed at workplace. It impacts the way people perceive the world. Jean Piaget, a noted Psychologist, said young children do move gradually from concrete to abstract thinking. It is nothing but reflecting one’s experience; they believe in what do they see and hear, trust the words what they hear. They would accept what one says, there is no question of asking questions. It is also called literal thinking, look for physical objects for proper understanding.

Example: Giving directions to others one has to use the language carefully. “Put the book on the table/ red book on the table.” The complex ideas are divided into small, parts /components and then each is concentrated separately, stay more mindful. problems are solved efficiently. In base ten for addition blocks of ten be used to carry out the addition. Using teaching aids make the learning easy, the ideas are made by simple showing objects. 

Example: To show a cube, defining what is an edge, face, vertices, can easily how many edges, faces, vertices are there in a cube. (E 12, F6, V8); 

Another example 4x3 ie 3 times of 4 can be shown by diagrammatic representation, 4things in a group, for 3 groups as 4 + 4+ 4 = 12. Multiplication as repeated addition.

Abstract Thinking: The word means theoretical /having no material existence/ notional / philosophical. There is abstraction in Mathematics, separated from physical and social world. Algebraic concepts are abstract. We say variables (dependent, independent) functions (onto, into one-one), equations, degree of equation, polynomials so on. When we count a number of objects after counting, we represent by a number (a symbol). The number can be representing the number of animals, tables in a class room, the number of days, the number of fruits, so on.  Abstract thinking is an ability to absorb through our senses, high order reasoning skills. It could be humor, wisdom, success, love, happiness, imagination. In brief a way of thinking not connected with physical objects. An example I would like to give. Suppose a project is given, to be completed. Normally one shall look for required steps and go ahead to complete. The question why this project is carried out, the purpose/need, is abstract thinking.

Lateral Thinking: It means indirect /finding other alternatives. It is essence of creativity. It is nothing but moving from known area to new areas. Lateral thinking is linked with Edward Do Bono. In fact, he popularized this kind of thinking. Another popular mathematician from Hungary George Polya. He had written a book “How to solve it”. A problem can be solved in different ways using different methods. Now a days we call it as an open-ended approach. In brief I would say, finding other alternatives to solve or find the solution.

Let me give some examples: 

Example :- A null among say 8 people. Let us say this game is under elimination. Every player loses one game. The question is how matches are to be played to find the winner. The answer is 7 matches are to be played. How arrived the answer?

Let us say the competitors be named as A, B, C, D, E, F, G, H. 

To start with, games between A&B, C& D, E&F, G&H ----------------------- 4 matches.

 Assuming B, C, F, H wins, now the games between B&C, F&H ------------2matches.

Assuming C, H wins, now the game will be between C & H    -------------- 1match

So total 7 matches are to be played. This kind of problem quoted by Mathematician---George Polya.

Another example: If electricity goes quite often one could think of UPS, Generator, another alternative. In case of un-employment problem, one can think of starting own business. It is the question, how one could be able to solve not only problems in mathematics but in real life situation too. Education, in that way helps an individual, value-oriented education is preparation of one’s life.

Another example:  Given 9 match sticks, one can easily 4 equilateral triangles, it will be diagram in 2D.

                                    

Instead given only 6 sticks, can we form 4 triangles of same shape and size. Yes, possible if one who thinks, beyond.

3 Dimension, forming a tetrahedron.    ---- be continued.
