### How Do Mathematicians Know Their Proofs Are Correct?

What makes a proof stronger than a guess? What does evidence look like in the realm of mathematical abstraction? Hear the mathematician Melanie Matchett Wood explain how probability helps to guide number theorists toward certainty.

### The Computer Scientist Who Parlays Failures Into Breakthroughs

Daniel Spielman solves important problems by thinking hard — about other questions.

### Unimaginable Surfaces Discovered After Decades-Long Search

Using ideas borrowed from graph theory, two mathematicians have shown that extremely complex surfaces are easy to traverse.

### Researchers Identify ‘Master Problem’ Underlying All Cryptography

The existence of secure cryptography depends on one of the oldest questions in computational complexity.

### Mathematician Hurls Structure and Disorder Into Century-Old Problem

A new paper shows how to create longer disordered strings than mathematicians had thought possible, proving that a well-known recent conjecture is “spectacularly wrong.”

### Researchers Defeat Randomness to Create Ideal Code

By carefully constructing a multidimensional and well-connected graph, a team of researchers has finally created a long-sought locally testable code that can immediately betray whether it’s been corrupted.

### How and Why Computers Roll Loaded Dice

Researchers are one step closer to injecting probability into deterministic machines.

### Solution: ‘Randomness From Determinism’

Readers’ modifications of a bean machine showed how deterministic laws are capable of producing random-seeming behavior.

### Mathematicians Calculate How Randomness Creeps In

Mathematicians have figured out exactly how many moves it takes to randomize a 15 puzzle.
