After escaping the Nazis by minutes and then getting smuggled through spy-infested Stockholm, the bomb bay of a British fighter jet might have been a relief to physicist Niels Bohr. His approach to ...

Theoretical physicists have proposed a new solution to the Schrödinger's cat paradox, which may allow the theories of quantum mechanics and Einstein's relativity to live in better harmony. The bizarre ...

Picture a cat. I’m assuming you’re imagining a live one. It doesn’t matter. You’re wrong either way—but you’re also right. This is the premise of Erwin Schrödinger’s 1935 thought experiment to ...

One of the most confounding concepts to emerge from the cauldron of early 20th-century physics was the idea that quantum objects can exist in multiple states simultaneously. A particle could be in ...

Quantum mechanics is one of the most successful theories in science — and makes much of modern life possible. Technologies ranging from computer chips to medical-imaging machines rely on the ...
