Quantum mechanics: a branch of physics that is, to many, confusing and misunderstood. It encompasses and deals with the actions and interactions between energy and both subatomic particles and atoms.

Out of order: quantum mechanics defies causal order. (Courtesy: Shutterstock/Sam72) An experiment has confirmed that quantum mechanics allows events to occur with no definite causal order. The work ...

Like great art, great thought experiments have implications unintended by their creators. Take philosopher John Searle’s Chinese room experiment. Searle concocted it to convince us that computers ...

TEACHERS searching for hints in arranging effective experiments in mechanics will find in this book a good deal to interest them. A large part of the volume is taken up with experiments on kinetics, ...

The double-slit experiment is the best demonstration of quantum weirdness, in which electrons simultaneously act like particles and waves and seemingly violate basic laws of physics. Now we’re trying ...

I WOULD like to take you with me, just for a minute or two, on a journey through space and time. We are minding our own business, watching the stars and galaxies zip by, when, suddenly, an invisible ...

Oil droplets guided by “pilot waves” have failed to reproduce the results of the quantum double-slit experiment, crushing a century-old dream that there exists a single, concrete reality. In 2005, a ...

Physicists developed detailed quantum mechanical simulations that accurately predict the outcomes of various additive combinations in water used for enhanced oil recovery. With their current approach, ...

Time travel has long been a subject of fascination in science fiction, but recent scientific endeavors suggest that it might not be as far-fetched as once thought. Researchers in laboratories around ...
