loved only numbers..... Paul Erdos (1913-1996)



He will be famous or rather infamous ( who got screwed in the paper by that question ) by the people who gave CAT ( a fucked up paper to some how test your management skills ..i never got the connection ) this year ( 2006). There was one question regarding Erdos numbers ( yeah i am talking about the same guy ) in DI section ( if u dont know what it means dont bother). Anyway he is considered the second most prolific mathematician only after the great Euler. I can bet not many people would have heard of him but he is something you should know about, maybe we can draw some inspiration from him to change our lives ( i doubt it though).

Paul Erdos was a Hungarian born mathematician famous for his brilliantly elegant proofs of seemingly unsolvable mathematical problems, especially in the area of numbers theory.
He founded the field of discrete mathematics, the foundation of computer science.

So thoroughly did Erdos devote himself to mathematics that he never married, acquired no property beyond a change of clothes ("Property is a nuisance."), and he refused to stay tied down to a job because it would limit his ability to focus on mathematical problems and to collaborate with distant colleagues. Instead he traveled from one place to another, living out of a half-empty suitcase, staying with fellow mathematicians and sharing ideas from one place to the next. Whatever money he acquired was soon given away, sometimes to charities but often as prizes to those who solved the difficult mathematical problems he set them.

After his siblings died before his birth at the ages of 3 and 5, he was the only child of Anna and Lajos Erdos. His parents were both Jewish mathematicians, from a vibrant intellectual community. He could add at age 3 and at age 4 he could calculate for friends of the family how many seconds they had lived. Erdos showed early promise as a prodigy, and soon became regarded as a mathematical genius by his peers.

Though kind hearted, warm, and likeable Erdos was known for his lack of social graces, the by-product of an unusually sheltered childhood. He was extremely coddled by his mother who had to raise him on her own for several years while his father (captured by the invading Russian army in WWI), was imprisoned in Siberia. It is said Erdos had never tied his own shoelaces until age 14 nor buttered his own bread until he was 21 years old. More significantly, he had been kept home from school (which his mother thought crawling with diseases) all through childhood and early adolescence. Well you dont have to be inspired with this.

As his colleague said, "a mathematician is a machine for turning coffee into theorems", and Erdos drank copious quantities. He also took amphetamines, despite the concern of his friends, one of whom bet him $500 that he could not stop taking the drug for a month. Erdos won the bet, but complained that mathematics had been set back by a month: "Before, when I looked at a piece of blank paper my mind was filled with ideas. Now all I see is a blank piece of paper." The bet won, he promptly resumed his amphetamine habit.

He had his own idiosyncratic vocabulary: he spoke of "The Book," an imaginary book in which God had written down the best and most elegant proofs for mathematical theorems."You don't have to believe in God, but you should believe in The Book." He himself doubted the existence of God, whom he called the "Supreme Fascist".

Other idiosyncratic elements of Erdos' vocabulary include:
children were referred to as "epsilons"
women were "bosses"
men were "slaves"
people who stopped doing math had "died"
people who died had "left"
alcoholic drinks were "poison"
music was "noise"
to give a mathematical lecture was "to preach."

He died "in action" of a heart attack. a book entitled "Proofs From The Book" has been published, intended as a collection of the most beautiful mathematical proofs in the spirit of Erdos.

What is your Erdos Number ? :

Because of his prolific output, friends created the Erdos number as a humorous tribute;
Erdos alone was assigned the Erdos number of 0 (for being himself),
while his immediate collaborators could claim an Erdos number of 1,
their collaborators have Erdos number at most 2, and so on.

Erdos numbers have also been humorously assigned to an infant, a horse and several actors.


Well this was pretty long but he deserved this. I have taken much of it from wiki, I admit but its worth reading it. Thanks for the patience and you werent then its your problem i guess.....

mathematicians.....

There is something about maths which is so pure, beautiful and subtle that i cannot explain. It doesnt mean that i am good at maths or something but this is something which fascinates me a lot. Simple logic , equations and representations which can solve most complex problems in the most elegant way is basically the beauty of maths. You know solving a good mathematical problem or puzzle in some elegant way is the second most pleasurable thing i think ( no points for guessing the first most pleasurable thing). I have always admired mathematicians and the mathematical world they live in. Most of them are eccentric or psychotic in their own ways. Here in my blog i will post some really interesting trivia about my favorite mathematicians. We hear a lot about famous physicist, biologists and chemists etc etc et c. But that is not enough, mathematicians play some really important role in our daily lifes, and being ignorant about them is like a crime or something. I mean they have done so much important work that even to comprehend that requires some skill. I dont know why and how they are left out so much on their important contributions but through this blog i will make a feeble attempt to put forward what ever i can so that people ( if you r sulking already buzz off) will appreciate it better. Dont worry i wont bore you with their mathematical achievements , as i am not competent enough to do justice with it. But definitely whenever i post at the bottom i will write some anecdotes about them or something. I will try to organize some material on the ones which are not so famous but deserve that glory and in the process will learn a lot. I hope you will appreciate this effort and will visit me again. Your comments will be most valuable as there will be a lot of ground to cover.

the pledge...the turn....the prestige...

I was surprised with the movie when i was through with it. It touched or rather discovered a complete different emotion in me . It became one of my favorites despite being in the different league of movies i watch. Its a christopher nolan movie so i had to see it. He has that uncanny ability to direct movies blending the characters with amazing screenplay and brilliant script. His previous movies like following and memento having non-linear story-telling sequence. Insomnia and batman begins have brilliant script and screen play with superb cast.
The Prestige is based on christopher priest novel with the same name. Its about two magicians who are obsessed with stealing each others secrets and how eventually christian bale with his superior tricks fools hugh jackman ultimately costing his life. the movie has one part which i specifically like in which christian bale talks about importance of secrets to magician. Scarlett johanssonn looks really cute in the movie after she has reduced much weight from lost in translation. This movie is about obsession, deceit and of course magic. Its really brilliant with the right cast in it.

chupke chupke (old).....hrishikesh mukherjee

Awesome. There are few movies in indian cinema which have such a wonderful combination of humor, family values, romance and of-course hindi as a language. I have seen this movie more than 30 times and i am never tired of watching it again. It has that subtle connection to our indian psyche using humor and romance as the key elements that i am amazed every time i watch it. Hrishikesh Mukherjee is a magician of movies. He uses simple incidents and regular tit-bits in everyone's daily life to generate such a beautiful mosaic of humor and romance that no body else i know of has done it. Be it golmaal , chupke-chupke and other social problems related movies, he uses simple characters and strong music aptly placed in the movie situations with beautiful lyrics to make the fabric of the movie. Its simply perfect. Besides the cast just goes with the plot so well that u cant imagine how it would have been without them or somebody else playing the part. He is my favorite director and a brilliant man to be. The simple plots contain deeper meaning, but are generally straightforward in form, theme and treatment. He directed around 50 films most of which were valued because of their middle-of-the-road accessibility, heart-warming irony and literary sensibilities.
The situation is based around a plot to fool sulekha's ( sharmila tagore) genius jijaji (om prakash) as she kept on praising him in front of her husband ( dharmendra) professor in botany. The plot is so simple but so well executed that i feeel refreshed every time i watch it.
Its a classic and i think every indian should be proud of such movies as part of our otherwise egregious hindi cinema (bollywood).
