A Proof That Some Spaces Can’t Be Cut
...dissertation adviser at Harvard, and Tomasz Mrowka, a topologist at the Massachusetts Institute of Technology, combined equations that originated in quantum physics with Floer homology to construct a powerful invariant...
Solution: ‘The Road Less Traveled’
...example from real science, beautifully described by Natalie Wolchover here in Quanta Magazine, is the amplituhedron, the jewel at the heart of quantum physics. In our case, the clever trick...
A Twisted Path to Equation-Free Prediction
...modeling began almost 100 years ago, and from the start it was influenced heavily by physics and engineering, which had used differential equations to describe dynamic systems for the previous...
Three Puzzles Inspired by Ramanujan
...lives, and is finding applications in computer science, string theory, and the mathematical basis of black hole physics. A monthly puzzle celebrating the sudden insights and unexpected twists of scientific...
How Our Reality May Be a Sum of All Possible Realities
...physics,” Dunne said. Despite its triumph in physics, the path integral makes mathematicians queasy. Even a simple particle moving through space has infinitely many possible paths. Fields are worse, with...
One Lab’s Quest to Build Space-Time Out of Quantum Particles
...particle physics or cosmology — a state of affairs that could continue indefinitely — this could be the most promising route for putting the latest ideas about quantum gravity to...
Physicists Find a Way to See the ‘Grin’ of Quantum Gravity
...physics. Perhaps, given the chance, the whip-smart Bronstein might have helped to speed things along. Aside from quantum gravity, he contributed to astrophysics and cosmology, semiconductor theory, and quantum electrodynamics,...
Janna Levin on Seeing and Hearing Black Holes
...time that would happen inside a black hole, and, and the laws of physics would break down in there. We still don’t even know what would happen inside of a...
