A persistent group of scientists at the University of Warsaw have accomplished the impossible by creating a hologram of a solitary particle of light, reports Business Insider.

The double-slit experiment is one of the most famous experiments in physics and definitely one of the weirdest. It demonstrates that matter and energy (such as light) can exhibit both wave and ...
