Wouldn't it be fascinating to live in New York and London at the same time? In the standard of everyday life, this is equivalent to daydreaming or sheer fantasy. Nevertheless, this is a perfectly ...

The physics of the microrealm involves two famous and bizarre concepts: The first is that prior to observation, it is impossible to know with certainty the outcome of a measurement on a particle; ...

Red and blue: a photon of two colours has been made. (Courtesy: iStock/-strizh-) Individual photons have been put into a quantum superposition of two different colours by a team of physicists in the ...

It's driving me nuts. Is the double bond constantly changing between all possibilities fast enough that it shortens the bond length for all, or are all the double bonds existing in all possible states ...

The world of quantum mechanics, where particles can be in two places at once or entangled with each other across vast distances, sounds spooky to us living in the macroscopic world of classical ...

Interrelated Superposition and entanglement can be observed independently of the theoretical framework used to explain them. (Courtesy: iStock_Traffic-Analyzer) When a forest loses its trees, it also ...

Forbes contributors publish independent expert analyses and insights. I write about physics, science, academia, and pop culture. When I teach or give talks about relativity, one of my regular angles ...

Topological defects are encountered in fields ranging from condensed-matter physics to cosmology. These broken-symmetry objects are intrinsically local, but theoretical work now suggests that ...
