The Cartoon Picture of Magnets That Has Transformed Science
...to model virtually every interesting thermodynamic phenomenon.” It has also penetrated far-flung disciplines well beyond physics, serving as a model of earthquakes, proteins, brains — and even racial segregation. Here’s...
Wheel Made of ‘Odd Matter’ Spontaneously Rolls Uphill
Physicists have solved a key problem of robotic locomotion by revising the usual rules of interaction between simple component parts. In a physics lab in Amsterdam, there’s a wheel that...
What Causes Giant Rogue Waves?
...you get to longer periods. Strogatz (10:40): Just to make sure I’m following because I think I know what period means, like, say in a first-year physics course, where I’m...
In a Multiverse, What Are the Odds?
Testing the multiverse hypothesis requires measuring whether our universe is statistically typical among the infinite variety of universes. But infinity does a number on statistics. If modern physics is to...
Quantum Darwinism, an Idea to Explain Objective Reality, Passes First Tests
Three experiments have vetted quantum Darwinism, a theory that explains how quantum possibilities can give rise to objective, classical reality. It’s not surprising that quantum physics has a reputation for...
The Universe’s Ultimate Complexity Revealed by Simple Quantum Games
A two-player game can reveal whether the universe has an infinite amount of complexity. One of the biggest and most basic questions in physics involves the number of ways to...
Cosmologists Debate How Fast the Universe Is Expanding
...Perlmutter of the Supernova Cosmology Project and Brian Schmidt and Adam Riess of the High-Z Supernova Search Team, won the 2011 Nobel Prize in Physics. Fast forward to July of...
Her Key to Modeling Brains: Ignore the Right Details
...a scientific perspective. It’s still a very cool area of physics for inspiring interesting math and making connections to all kinds of mathematics that aren’t typically considered applied. But from...
Diminishing Dark Energy May Evade the ‘Swampland’ of Impossible Universes
...physics, which has long predicted that space should be suffused with substantial amounts of energy. The quantum fields that permeate space fluctuate in strength, never staying exactly at zero; particles...
