...and the United Kingdom; then, at 29, she was invited back to Mexico to run the theoretical physics department of the Mesoamerican Center for Theoretical Physics. A few years later,...
Troubled Times for Alternatives to Einstein’s Theory of Gravity
...September 2017, he was at the Institute for Theoretical Physics in Saclay, near Paris, to speak at a meeting about dark energy and modified gravity. The official news had not...
The Universe Is Not a Simulation, but We Can Now Simulate It
...a different approach to this abridgement, picking and programming what they saw as the key astrophysics. Then, in 2012, a study by Cecilia Scannapieco of the Leibniz Institute for Astrophysics...
The Strange Numbers That Birthed Modern Algebra
The 19th-century discovery of numbers called “quaternions” gave mathematicians a way to describe rotations in space, forever changing physics and math. Imagine winding the hour hand of a clock back...
What Can Jellyfish Teach Us About Fluid Dynamics?
...physics. And so there was a movement that emerged, now a couple of decades ago, to say: Why don’t we study some animal systems that have already figured it out,...
The Mathematical Structure of Particle Collisions Comes Into View
...Their method may help bring about new levels of predictive accuracy, which theorists desperately need if they are to move beyond the leading but incomplete model of particle physics. “They...
How Radio Astronomy Reveals the Universe
Radio waves, longer and less energetic than visible light, give astronomers access to some of the most obscure physics in the cosmos. If you ask an astronomer to choose the...
Virginia Trimble Has Seen the Stars
...on to become one of the first women to earn a doctorate in astrophysics at the California Institute of Technology. While she was there, she befriended Richard Feynman, who paid...
How the Bits of Quantum Gravity Can Buzz
...Wilczek and Zahariade’s calculation is built on physics that few would disagree with. “We did a very conservative calculation, which is almost certainly correct,” said Parikh. “It essentially just assumes...
