The Colorful Problem That Has Long Frustrated Mathematicians
The four-color problem is simple to explain, but its complex proof continues to be both celebrated and despised.
How Do You Prove a Secret?
Zero-knowledge proofs allow researchers to prove their knowledge without divulging the knowledge itself.
Computer Science Proof Unveils Unexpected Form of Entanglement
Three computer scientists have posted a proof of the NLTS conjecture, showing that systems of entangled particles can remain difficult to analyze even away from extremes.
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.
Can Computers Be Mathematicians?
Artificial intelligence has bested humans at problem-solving challenges like chess and Go. Is mathematics research next? Steven Strogatz speaks with mathematician Kevin Buzzard to learn about the effort to translate math into language that computers understand.
The Computer Scientist Who Parlays Failures Into Breakthroughs
Daniel Spielman solves important problems by thinking hard — about other questions.
How Computer Scientists Learned to Reinvent the Proof
Why verify every line of a proof, when just a few checks will do?
How to Write Software With Mathematical Perfection
Leslie Lamport revolutionized how computers talk to each other. Now he’s working on how engineers talk to their machines.
In Music and Math, Lillian Pierce Builds Landscapes
Lillian Pierce wants to transform access to the world of mathematics, while making headway on problems that bridge the discrete and continuous.
