Does Time Really Flow? New Clues Come From a Century-Old Approach to Math.
The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers. Strangely, although...
The Quantum Secret to Superconductivity
...Philip Anderson, a Nobel Prize winner and one of the founders of condensed-matter physics, advanced in the 1980s. Sachdev posits a kind of order in cuprates that isn’t seen in...
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...
Physicists Reveal a Quantum Geometry That Exists Outside of Space and Time
...Coke and an inexhaustible enthusiasm for physics. Arkani-Hamed and his collaborators aspire to bring about a conceptual revolution of the sort that rocked physics in the late 1700s. Joseph-Louis Lagrange...
The Computer Scientist Who Builds Big Pictures From Small Details
...Statistical Physics of Computation Laboratory at the Swiss Federal Institute of Technology Lausanne. Her work currently focuses on how the physics of phase transitions in matter — such as water...
