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

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 ...

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 ...

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

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 ...

A He-Ne laser shines on an adjustable single slit to make a diffraction pattern. The slit can be adjusted in two dimensions. Mount the laser and slit on opposite ends of the rail, making sure the ...
