The Thought Emporium

Saying that quantum mechanics is weird is massive understatement. As we explore smaller and smaller scales, the rules of nature become less intuitive. Originally scientists assumed that the smallest things were point like particles and built their models around this idea. But this all came crashing down thanks to the famous double slit experiment. Suddenly it was shown that light can behave like a wave. At first it was assumed that light is purely a wave but thanks to Louis de Broglie, we now know that almost all fundemental particles, and even collections of particles can exhibit wave like properties.

In this video we explore how the double slit experiment can be preformed using only candle soot and a laser pointer.

Since light has wave properties, we can exploit them using a device called an interferometer. These devices are the heart of some of the most advanced physics experiments on earth, including LIGO, the redefinition of the Kg and many others. Here we explore how a simple interferometer can be made at home.
