read this interesting interview with Henri Cartan (American Mathematical Society)

Notices: What are your memories of

Grothendieck?

Cartan: He is an exceptional man, of

course. He had a great influence on

some parts of mathematics, notably algebraic

geometry. His approach was

something new—though not completely

new, because at the beginning, for instance,

he himself was influenced by

Serre. Grothendieck is a very special

man. Nobody knows

He is very known to be one of the founders of the Bourbaki group. They published treaties over some subjects (including calculus, analysis, algebra) with methods quite revolutionary. Their books are still quite a reference in France. They wanted to change the way maths were taught and fought against it.

And his father is well-known too : Élie Cartan, who mostly contributed to the Lie groups if I remember well.

104 years is a pretty beautiful age. - August 25th 2008, 10:59 PMThePerfectHacker
Too add something on the Bourbaki group.

The Bourbaki group was a reaction against Poincare'.

They wanted to introduce mathematical formalism.

You can see this if you read the six volume Bourbaki books.

They start with Set Theory.

And build it up from there all the way up to Lie algebra.

They wish to show how everything is connected to eachother. - August 30th 2008, 12:51 PMMathGuruAnother interesting article

Mathematical formalism is one of the most beautiful things in the universe. RIP Cartan - be remembered ever.
