Physicists Use Quantum Mechanics to Pull Ener...

Together, Charles Bennett and Gilles Brassard figured out how to use the laws of quantum physics to keep secret messages safe from eavesdroppers. Their efforts have earned them one of the highest awards in computing and a $1 million prize. On this episode of The Quanta Podcast, h ...  Show more

Is string theory the one true “theory of everything?” Some physicists swear it’s a fundamental ingredient of nature. Others wish it would just go away. On this episode of The Quanta Podcast, host Samir Patel speaks with columnist Natalie Wolchover about the mathematical developme ...  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

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 ...

<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 ...

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
