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...
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...
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....
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...
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,...
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...
Are There Reasons to Believe in a Multiverse?
...which is associated with the new physics which is beyond the Standard Model. Strogatz (15:10): I see, yeah. Kaplan: So instead of saying there’s some unknown physics so far above...
In the Hunt for Dark Matter, Promises to Keep?
...to another subatomic particle called a neutrino in that it rarely interacts with other matter. With the discovery of the Higgs boson last year, one era of particle physics has...
