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...
Particle Physicists Detect ‘Magic’ at the Large Hadron Collider
...place but are very capable of addressing.” This convergence of quantum information theory and particle physics “really is an emergent field,” said Regina Demina, a physicist at the University of...
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...
Physicists Argue That Black Holes From the Big Bang Could Be the Dark Matter
...come back to life. In one of the latest, published last week in the Journal of Cosmology and Astroparticle Physics, Karsten Jedamzik, a cosmologist at the University of Montpellier, showed...
New Black Hole Math Closes Cosmic Blind Spot
...weigh more than 10 solar masses. Earlier this year, researchers at the Max Planck Institute for Gravitational Physics used Field and Khanna’s surrogate model to look through LIGO data for...
