Mathematicians Of The Day
29th April
On this day in 1901, Lebesgue published his famous paper Sur une généralisation de l'intégrale définie in the Comptes Rendus of the French Academy of Sciences. In this he gave the definition of the Lebesgue integral that generalises the notion of the Riemann integral by extending the concept of the area below a curve to include many discontinuous functions.

Quotation of the day
From Ludwig Wittgenstein
Death is not an event in life; we do not experience death.
