I had been to Kumbakonam last week and I was there at Srinivasa Ramanujam’s house which is located at Sarangapani kovil street. It’s unfortunate that one is not allowed to take photographs inside the house. I request people at Sastra University to allow photography inside the house.

### Visualising Equations

x*(x-a^2)*(x+b-a^2)*(x+a^2)*(x+b+a^2)+y^2-z^2 = 0 for (a = 0, b = 0.36)

(x^2+y^2+z^2-(0.5+2*a)^2)^2-(3.0*((0.5+2*a)^2)-1.0)/(3.0-((0.5+2*a)^2))*(1-z-sqrt(2)*x)*(1-z+sqrt(2)*x)*(1+z+sqrt(2)*y)*(1+z-sqrt(2)*y) = 0 for (a = 0.43)

x^3+y^3+z^3+1-0.5*a*(x+y+z+1)^3 = 0 for (a = 1)

x*y*z = 0

(x^2+9/4*y^2+z^2-1)^3-x^2*z^3-9/80*y^2*z^3 = 0

x^2/(a+0.05)^2+y^2/(b+0.05)^2-z^2-1 = 0 for (a = 1, b = 1)

x^3+y^3+z^3+1-0.5*a*(x+y+z+1)^3 = 0 for (a = 1)

All the above graphs were generated using Surfer software. It ire real fun to play with it and vizualize the equations.

Beauty depends on size as well as symmetry. – Aristotle

Honestly, I do not know relation between beauty and maths, thankfully that doesn’t stop me from appreciating it. Macro shot taken with Nikon S10. Diptych to give two different perspective. The background is Thailand’s Grand Palace

### Ramaujan’s Letter to Hardy

Published August 1, 2007 Uncategorized 10 CommentsTags: G.H. Hardy, Great Letters, Mathematics, Maths, Srinivasa Ramujan

Madras 16th January 1913

Dear Sir

I beg to introduce myself to you as a clerk in the Accounts Department of the Port Trust Office at Madras on a salary of £ 20 per annum. I am no about 23 years of age. I have had no university education but I have undergone the ordinary school. I have been employing the spare time at my disposal to work at Mathematics. I have not toddle through the conventional regular course, but I am striking out a new path for my self. I have made a special investigation of divergent series in general and the results I get are termed by the local mathematicians as “Startling”

…

I would request you to go through the enclosed papers. Being poor, if you are convinced that there is anything of value I would like to have my theorems to be published. I have not given te actual investigation nor expressions that I get but I have indicated the lines on which I proceed.

Being inexperienced I would very highly value any advice you give me. Requesting to be excused for the trouble I give you.

I remain

Dear Sir

Your truly

S.Ramanujan

*Hardy’s reply*

Dear Sir

I was exceedingly interested by your letter and by theorems…

Your will how ever understand that before I can judge properly the value of what you have done, it is essential that I should see proofs of some of your assertions.

..

I want particularly to see your proofs of your assertions have. You will understand that, in this theorym everything depends on rigorous exactation of proof..

People have math phobia because they have to comprehend ~~theorem~~ like the one below.

A solid ball may be separated into a finite number of pieces and reassembled in such a way as to create two solid balls, each identical in shape and volume to the original.

Now, think of having spherical currency in circulation. That would be Sweet!

One night Georges Cuvier was visited by the devil. One of his students dressed up with horns on his head and shoes shaped like cloven hooves. This frightening apparation burst into Cuvier’s bedroom when he was fast asleep and claimed:

“Wake up thou man of catastrophes. I am the devil. I have come to devour you!”

Cuvier studied the apparation carefully and critically said, “I doubt whether you can. You have horns and hooves. You eat only plants.”

I don’t like electrons; they’ve always had a negative influence on society. (Chris Lipe)

Most prime numbers are even. Proof: pick up any math text and look for a prime number. The first one you find will probably be even.1
