How a Computer Broke a 50-Year Math Record

Christopher Webb Young/Quanta Magazine; Emily Zhang for Quanta Magazine

undefined NaN, NaN

DeepMind researchers trained an AI system called AlphaTensor to find new, faster algorithms for matrix multiplication. AlphaTensor quickly rediscovered — and surpassed, for some cases — the reigning algorithm discovered by German mathematician Volker Strassen in 1969.

Could One Physics Theory Unlock the Mysteries of the Brain?

Taylor Hess, Noah Hutton, Emily Buder, Rui Braz and Myriam Wares for Quanta Magazine

undefined NaN, NaN

The phenomenon of criticality can explain the sudden emergence of new properties in a wide range of complex systems, from avalanches to flocks of birds to stock market crashes. Neuroscientists are now seeking evidence that criticality is at work in the brain’s networks of neurons.

2022’s Biggest Breakthroughs in Math

Christopher Webb Young (video) and Myriam Wares (cover) for Quanta Magazine

undefined NaN, NaN

In 2022, mathematicians solved a centuries-old geometry question, proved the best way to minimize the surface area of clusters of up to five bubbles and proved a sweeping statement about how structure emerges in random sets and graphs.

Wormhole in the Lab

Emily Buder, Bongani Mlambo, Ibrahim Rayintakath, Rui Braz and Kim Taylor for Quanta Magazine; Kristina Armitage/Quanta Magazine

undefined NaN, NaN

Wormholes were first envisioned almost a century ago, but it would take a number of theoretical leaps and a “crazy” team of experimentalists to build one on a quantum computer.
