Happy Easter and IMAGINARY Easter eggs...
Apr. 2, 2013

Last week Holi was celebrated in India (with a lot of colours) and this week Easter in the Christian world (with equally many colours). Happy celebrations! Easter eggs are very popular within the IMAGINARY team, not the chocolate ones, but the ones you hide within a software program. We hid two Easter eggs in our museum exhibits: one in the MiMa museum in Oberwolfach and one in the MoMath museum in New York. They are...Read more

Mathematics of Planet Earth

Mathematics of Planet Earth 2013 (MPE2013) is an initiative of mathematical sciences organizations around the world designed to showcase the ways in which the mathematical sciences can be useful in tackling our world’s problems. The exhibition “Mathematics of Planet Earth” was created by the community through a competition: The winning modules are now part of this open source exhibition, staged in 2013 and onwards!

IMAGINARY – through the eyes of mathematics

“IMAGINARY – through the eyes of mathematics” is an interactive travelling exhibition by the Mathematischen Forschungsinstituts Oberwolfach originally developed for the Year of Mathematics 2008 in Germany.

Formulas
May. 23, 2013

In an interview with Villani in Le Monde, I found the following concerning the bunch of formulas in the book:

“La mathématique, c’est comme tout : cela peut se raconter à n’importe quel degré de complexité. D’ailleurs, l’une des raisons de mentionner dans mon…Read more

”[…] ich bin weit von Perelmans Niveau entfernt, und nehme an, ohne mich zu zieren.”

I rememberd another detail from the FAZ article about the book. When asked whether he thought about rejecting the Fields medal as Perelman did in 2008, Villani replied: “I am not genius enough” (or at least something similar). What did he mean by that?
