Math and Science News from Quanta Magazine View this email in your browser QUANTUM PHYSICS | ALL TOPICS   Physicists Use Quantum Mechanics to Pull Energy out of Nothing By CHARLIE WOOD The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works. Read the article EXPLAINERS   How Our Reality May Be a Sum of All Possible Realities By CHARLIE WOOD Richard Feynman's path integral is both a powerful prediction machine and a philosophy about how the world is. But physicists are still struggling to figure out how to use it, and what it means. Read the article MATHEMATICAL PHYSICS   A New Kind of Symmetry Shakes Up Physics By KEVIN HARTNETT Symmetry has been a crucial ingredient in every major advance in physics for more than a century. In recent years, symmetries have been reformulated into a form that can now be applied to quantum field theory, promising new breakthroughs. Read the article ASTRONOMY   Astronomers Say They Have Spotted the Universe's First Stars By JONATHAN O'CALLAGHAN Theory has it that "Population III" stars brought light to the cosmos. The James Webb Space Telescope may have just glimpsed them. Read the article THEORETICAL PHYSICS   'Alien Calculus' Could Save Particle Physics From Infinities By CHARLIE WOOD Feynman diagrams brought a measure of meaning to the infinities of quantum electrodynamics. But deep down, this way of approaching quantum field theory doesn't really work at all.
