Betting on the Future of Quantum Gravity
...professor of particle physics at Imperial College London and Bern’s frequent opponent. Each loss has its consolation prize, however. As Bern and his team pull off increasingly sophisticated calculations, the...
Alice and Bob Meet the Wall of Fire
...of three cherished notions in theoretical physics must be wrong. When Alice’s fiery fate was proposed this summer, it set off heated debates among physicists, many of whom were highly...
A Fight for the Soul of Science
...declared a “battle for the heart and soul of physics.” The crisis, as Ellis and Silk tell it, is the wildly speculative nature of modern physics theories, which they say...
As Supersymmetry Fails Tests, Physicists Seek New Ideas
...presented last week at the Hadron Collider Physics conference in Kyoto, Japan, ruled out another broad class of supersymmetry models, as well as other theories of “new physics,” by finding...
Is Nature Unnatural?
On an overcast afternoon in late April, physics professors and students crowded into a wood-paneled lecture hall at Columbia University for a talk by Nima Arkani-Hamed, a high-profile theorist visiting...
Decoding the Secrets of Superconductivity
...change how you transport electricity and enable new ways of using electricity,” said Louis Taillefer, a professor of physics at the University of Sherbrooke in Quebec. Materials that superconduct under...
A Common Logic to Seeing Cats and Cosmos
...and ubiquitous mathematical techniques in physics, a procedure for calculating the large-scale behavior of physical systems such as elementary particles, fluids and the cosmos. The new work, completed by Pankaj...
How Life (and Death) Spring From Disorder
What’s the difference between physics and biology? Take a golf ball and a cannonball and drop them off the Tower of Pisa. The laws of physics allow you to predict...
A New Spin on the Quantum Brain
...when he published a paper in Annals of Physics proposing that the nuclear spins of phosphorus atoms could serve as rudimentary “qubits” in the brain — which would essentially enable...
