A Physicist’s Physicist Ponders the Nature of Reality
Edward Witten reflects on the meaning of dualities in physics and math, emergent space-time, and the pursuit of a complete description of nature. Among the brilliant theorists cloistered in the...
What Is Quantum Field Theory and Why Is It Incomplete?
...and then simulating. And yet there’s a fundamental obstacle seemingly to discretizing the laws of physics as we know it. So we can’t simulate the laws of physics, but it...
Frank Wilczek on the Strong Force, Quarks and Dark Matter
...of the greatest accomplishments in theoretical physics over the past hundred years, including an explanation for the strong nuclear force and key contributions to our understanding of quantum chromodynamics. This...
Is Perpetual Motion Possible at the Quantum Level?
...physics at Stanford University. In 2021, she received the New Horizons in Physics Prize from the Breakthrough Prize Foundation for her work on non-equilibrium quantum matter, including time crystals. She...
Rumors Cast Doubt on Diphoton Bump
...that this 750-GeV bump, if it keeps growing, could signify a new fundamental particle. Unlike the Higgs, which was predicted by the Standard Model of particle physics, the new particle...
The Art of Teaching Math and Science
...in popularity among physics teachers. Modeling instruction won the 2014 Excellence in Physics Education Award from the American Physical Society and has been shown to yield higher scores than traditional...
She Turns Fluids Into ‘Black Holes’ and ‘Inflating Universes’
...“It’s mind-blowing how physics really works,” she told me recently. “It just seems like nature threw us a bone when things are really hard.” The hard physics that’s out of...
A Call for Courage as Physicists Confront Collider Dilemma
...All the world is built out of 17 known elementary particles. Carlo Rubbia led the team that discovered two of them. In 1984, Rubbia shared the Nobel Prize in Physics...
Hopes of Big Bang Discoveries Ride on a Future Spacecraft
...physics at the time, and his interests seemingly lay elsewhere. Particle physicists seek the more fundamental truth underpinning the physical rules we’re familiar with. They’ve long used high-energy particle colliders...
