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; ...

Three's company: interference patterns for one to four slits (expand for full image) A group of physicists in Austria has directed a beam of large molecules at a series of extremely narrow slits to ...

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 ...

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 ...

The famous paradox of Schrödinger’s cat starts from principles of quantum physics and ends with the bizarre conclusion that a cat can be simultaneously in two physical states – one in which the cat is ...

Scientists created quantum superposition states at temperatures up to 60 times hotter than their environment, challenging the assumption that quantum effects require extreme cold. This discovery could ...

PHYSICS HAS A problem. In general relativity, time is entwined with space. It is relative, depending on speed or gravity. In quantum mechanics, however, time is an absolute. It is a smooth background ...

All the circuits that we have analyzed are linear circuits and we must be more specific in defining a linear circuit. We can consider the most important consequence of linearity, the principle of ...
