Explore our surprisingly simple, absurdly ambitious and necessarily incomplete guide to the boundless mathematical universe.
How Randomness Can Make Math Easier
Randomness would seem to make a mathematical statement harder to prove. In fact, it often does the opposite.
Random Surfaces Hide an Intricate Order
Mathematicians have proved that a random process applied to a random surface will yield consistent patterns.

Equations, like numbers, cannot always be split into simpler elements.
New Theory Cracks Open the Black Box of Deep Learning
A new idea is helping to explain the puzzling success of today’s artificial-intelligence algorithms — and might also explain how human brains learn.
Solution: ‘A Drunkard’s Walk in Manhattan’
City blocks help illustrate why walking randomly tends to take you away from your starting point.
A Drunkard’s Walk in Manhattan
Why is it that when you walk randomly, the more you walk, the farther you get from your starting point?
