Physicists Use Quantum Mechanics to Pull...

Particle physics hasn't yet found the new physics needed to resolve its deepest mysteries. It’s hard to know what to think about or look for. But the most devoted particle physicists are thinking and looking all the same. On this episode, host Samir Patel and columnist Natalie Wo ... Show More

Reversible programs run backward as easily as they run forward, saving energy in theory. After decades of research, they may soon power AI.The story How Can AI Researchers Save Energy? By Going Backward first appeared on Quanta Magazine. 

We already know that what we eat, drink, and inhale can affect which parts of our DNA are expressed, and which aren’t. But recent research poses a shocking idea: A dad’s habits may be encoded in molecules and transmitted to his future kids. On this episode, host Samir Patel and b ... Show More

An examination of some more advanced concepts of quantum mechanics, focusing on describing Dirac's bra-ket formulation of quantum theory. I discuss the formulation of quantum mechanics in terms of vectors in Hilbert spaces, Hermitian operators as corresponding to observables, ort ... Show More

<p>Aristotle argued almost 2,400 years ago that a perfect vacuum could never exist. Today, the concept of nothingness figures at least implicitly into almost every theory of modern physics. In this episode closing out season 2 of “The Joy of Why,” the theoretical physicist Isabel ... Show More

<p><span style="font-weight: 400">Quantum field theory may be the most successful scientific theory of all time, predicting  experimental results with stunning accuracy and advancing the study of higher dimensional mathematics. Yet, there’s also reason to believe that it is missi ... Show More

This month’s episode of the Physics World Stories podcast looks in depth at the science behind the 2022 Nobel Prize for Physics and the technologies that are emerging as a result. Alain Aspect, John Clauser and Anton Zeilinger shared this year’s award “for their experiments with ... Show More

<p>Quantum mechanics and general relativity are two of the most successful theories of science ever, but they don&apos;t necessarily fit together. Learn why physicists are trying so hard to discover a quantum theory of gravity, and why it&apos;s been such a challenge.<br/><br/>Fo ... Show More

Quantum mechanics is full of weird findings – for example, that systems widely separated can somehow still be correlated, and that a system may be in two different possible states at the same time. Entanglement and superposition, among other phenomena, have prompted debate since ... Show More

The secret to making a qubit for future quantum computers might depend on knowing how to tie knots in unusual materials, argues the physicist Charlie Marcus. The post Charlie Marcus Knows That Quantum Facts Aren’t Complicated first appeared on Quanta Magazine
