The speed of light is one of the most fundamental constants in physics, yet it has never been directly measured in one ...

Here, a calcite crystal is struck with a laser operating at 445 nanometers, fluorescing and displaying properties of birefringence. Unlike the standard picture of light breaking into individual ...
