By Lê Nguyên Hoang, Not an Ordinary Seminar – GERAD. March 6th, 2013.
In this talk, I will take you through some of the greatest simple ideas of the 20th century. From operations research to topology, from set theory to graph theory, from fractals to infinity, we will explore different regions of the world of mathematics. While this presentation is primarily aimed at non-mathematicians, it should be of great interest to everyone.

Euler's Formula and the Utilities Problem
By Lê Nguyên Hoang | Updated:2016-01 | Views: 18559
I was a kid when I was first introduced to the deceptively simple utilities problem. It's only lately that I've discovered its solution! And it's an amazing one! Indeed, it provides a wonderful insight into some fundamental mathematics, including Euler's formula! This is nothing less than the gateway to the wonderful world of algebraic topology!
Poincaré Conjecture and Homotopy

Poincaré conjecture is the most recent major proven theorem. Posited a century ago by Henri Poincaré, this major conjecture of topology was solved by Gregori Perelman. It has revolutionized our understanding of space and raised intriguing questions regarding the global structure of our Universe.
