On May 7, 1981, influential physicist Richard Feynman gave a keynote speech at Caltech. Feynman opened his talk by politely rejecting the very notion of a keynote speech, instead saying that he had ...

The acceptance of molecules as 3D structures led to major advances in chemistry, with quantum mechanics providing the theoretical framework. Early successes, like modeling the neutral H2 molecule, ...

The seeds of quantum theory were sown by Albert Einstein and others as early as 1905. But the theory came together properly 100 years ago in 1925 – and has exerted its influence ever since, as this ...

In the 1920s, when quantum mechanics was young, physicists Jane Dewey and Laura Chalk performed some of the first experimental tests of the theory, based on a phenomenon called the Stark effect. Later ...

The race to harness quantum mechanics for computing power is finally colliding with the real economy. After a century of ...
