The Basic Algebra Behind Secret Codes and Space Communication
Whether you’re passing secret notes in class or downloading images from a space probe, Reed-Solomon codes offer an ingenious way to embed information and correct for errors.
Mathematicians Roll Dice and Get Rock-Paper-Scissors
Mathematicians have uncovered a surprising wealth of rock-paper-scissors-like patterns in randomly chosen dice.
Finally, a Fast Algorithm for Shortest Paths on Negative Graphs
Researchers can now find the shortest route through a network nearly as fast as theoretically possible, even when some steps can cancel out others.
Probability and Number Theory Collide — in a Moment
Mathematicians are taking ideas developed to study random numbers and applying them to a broad range of categories.
Google Researcher, Long Out of Math, Cracks Problem About Sets
On nights and weekends, Justin Gilmer attacked an old question in pure math using the tools of information theory.
‘Nasty’ Geometry Breaks Decades-Old Tiling Conjecture
Mathematicians predicted that if they imposed enough restrictions on how a shape might tile space, they could force a periodic pattern to emerge. But they were wrong.
