The Bohr model, introduced by Danish physicist Niels Bohr in 1913, was a key step on the journey to understand atoms. Ancient Greek thinkers already believed that matter was composed of tiny basic ...

Scientists propose a link between string field theory and quantum mechanics that could open the door to using string field theory as the basis of all physics. Their calculations "could solve the ...

In a study, physicists now observed a class of quantum particles called fractional excitons, which behave in unexpected ways and could significantly expand scientists' understanding of the quantum ...

For a century, quantum theory has been scientific orthodoxy. The Italian physicist Angelo Bassi is certain it isn’t the full story — and that he can prove it. Credit...Illustration by Christiana ...

Rapid advances in applying artificial intelligence to simulations in physics and chemistry have some people questioning whether we will even need quantum computers at all. Tech companies have been ...
