On a December day, Richard Feynman gave a fun little lecture at Caltech — and dreamed up an entirely new field of physics. During the talk, entitled "Plenty of room at the bottom," he described the ...

Classical physics suggests that objects move along a single, well-defined path. Quantum mechanics says something far stranger: particles explore every possible path simultaneously. According to ...

At first glance, some scientific research can seem, well, impractical. When physicists began exploring the strange, subatomic ...

The hydrogen molecule H 2 is the simplest stable molecule, with two protons and two electrons bound together. Scientists have studied it for more than a century because it’s small enough that theory ...

Where next? Quantum metrology, fusion and medical physics are three hot topics to be featured on Physics World Live this year. (Courtesy: iStock/shutter_m) I used to set myself the challenge every ...
