During its teenage and young adult years—what is now referred to as its “classical” period—physics made a lot of mistakes. In the old physics, mass and energy were separately conserved; particles’ ...

Researchers at the University of Basel and the Laboratoire Kastler Brossel have demonstrated how quantum mechanical entanglement can be used to measure several physical parameters simultaneously with ...

Classical physics theories suggest that when two or more electromagnetic waves interfere destructively (i.e., with their electric fields canceling each other out), they cannot interact with matter. In ...

With simple arguments, researchers show that nature is complicated! Researchers have made a simple experiment that demonstrates that nature violates common sense. The experiment illustrates that light ...

Out with the old: Many undergraduate physics curricula need revamping. (Courtesy: iStock/Pobytov) Physics education has a high inertia towards change. While high-school students in today’s biology ...

For the first time, researchers have produced experimental evidence that classical chaos occurs in the quantum world. Chaotic behavior is the rule, not the exception, in the world we experience ...

Do the laws of quantum mechanics place any limits on how well a classical experimentalist can characterize the state and dynamics of a large quantum system? As a thought experiment, consider that we ...
