What Could Explain the Gallium Anomaly?

Emmy Noether showed that fundamental physical laws are just a consequence of simple symmetries. A century later, her insights continue to shape physics.“The post How Noether’s Theorem Revolutionized Physics first appeared on Quanta Magazine. 

The Busy Beaver Challenge, an open online collaboration, started in 2022 to finally solve a major problem in theoretical computer science. Over time, the online community grew to include more than 20 contributors from around the world, most of them without traditional academic cr ... Show More

Turbulence is a notoriously difficult phenomenon to study. Mathematicians are now starting to untangle it at its smallest scales.This is the sixth episode of The Quanta Podcast. In each episode, Quanta Magazine editor in chief Samir Patel speaks with the minds behind the award-wi ... Show More

Dark energy, the mysterious force powering the expansion of the universe, appears to be weakening over time, according to a major cosmological survey that has thrown the laws of modern physics into doubt. Ian Sample tells Madeleine Finlay how this new finding could shed light on ... Show More

Imaginez un univers où tout ce que nous voyons — les étoiles, les planètes, les objets autour de nous — est fait de minuscules particules appelées électrons. Ces électrons sont des composants essentiels de la matière, et ils ont tous des propriétés identiques : même charge électr ... Show More

As an experimental facility, the Large Hadron Collider at CERN in Geneva has been extraordinarily successful, discovering the Higgs boson and measuring multiple features of particle-physics interactions at unprecedented energies. But to theorists, the results have been somewhat f ... Show More

Quantum computing promises unprecedented speed, but in practice, it’s proven remarkably difficult to find important questions that quantum machines can solve faster than classical ones. One of the most notable demonstrations of this came from Ewin Tang, who rose to prominence in ... Show More

Black holes are objects that seem exotic to us because they have properties that boggle our comparatively mild-mannered minds. These are objects that light cannot escape from, yet glow with the energy they have captured until they evaporate out all of their mass. They thus have t ... Show More

En mars 2022, une partie d'une fusée chinoise, qui pourrait correspondre à son étage supérieur, ou à un propulseur, s'est écrasée sur la face cachée de la Lune. Un événement auquel s'attendaient les astronomes. Mais ce qui intrigue davantage les scientifiques américains, qui ont ... Show More
