Paradoxical Crystal Baffles Physicists
...“On the basis of established wisdoms this cannot possibly happen, and henceforth completely new physics should be at work.” It is too soon to tell what, if anything, this “new...
Responding Rapidly to Big Discoveries
...to three-week-long rapid response workshops are rush-approved and scheduled within six months. Similar programs are held at the Aspen Center for Physics and the Galileo Galilei Institute for Theoretical Physics....
Physicists Close In on ‘Perfect’ Optical Lens
...decade ago, but by achieving it in novel ways, two groups “have made negative refraction a practical reality at optical frequencies,” said Sir John Pendry, a professor of physics at...
Does Nothingness Exist?
...call it nothing? After all, there could still be energy inside or perhaps subatomic matter and particles that we just can’t see. In modern physics, this idea of nothingness has...
Droplets That ‘Come to Life’
...these active-droplet “protocells” divided and proliferated, evolution could have acted on them, gradually making them more complex and leading to the rise of living cells. The physics of active-droplet division...
After Black Holes Collide, a Puzzling Flash
...the same black-hole merger that produced the gravitational waves observed by LIGO (the Laser Interferometer Gravitational-Wave Observatory). The correlation, which is far from certain, would upend entrenched assumptions in physics....
The New Laws of Explosive Networks
...they break — has arisen from the physics of coffee. Researchers usually think of network connectivity as happening in a slow, continuous manner, similar to the way water moves through...
How to Understand the Universe When You’re Stuck Inside of It
...there’s nothing outside the universe — there’s no observer outside the universe — implies that we need a formulation of physics without background structure. All the theories of physics we...
A Defense of the Reality of Time
...reality. Change is real, as opposed to an illusion or an artifact of perspective. The laws of physics act within time to generate each moment. Mixing mathematics, physics and philosophy,...
