Physicists in China have brought one of Einstein’s thought experiments into reality—but not quite with the outcome he hoped for.

The subtlest experiment in quantum mechanics is also one of the simplest: send a stream of particles through two openings in a barrier, and you’ll produce an interference pattern because the particles ...

Can a photon be caught behaving like a wave and a particle in the same run of an experiment? For almost a century, that ...

The double-slit experiment is the most famous and probably the most important experiment in quantum physics: individual particles are shot at a wall with two openings, behind which a detector measures ...

A single atom as a movable slit: Researchers realize Einstein's thought experiment in original form, observing ...

Light has always been the stage on which quantum mechanics performs its strangest tricks, and the double-slit experiment is ...

Classical Physics (Physics established mostly by Newton), has one property that we may think that is universal, which is, certainty. For example, by using the mathematics of Newton, we can precisely ...
