Dr Quantum - Double Slit Experiment

How many times have you heard this? "If a tree falls in the woods, and there is no body there to hear it, does it make a sound?" Or have you ever heard of the Schrodenger's Cat theorem?

Well both of these thought experiments are based on quantum events, where matter and energy become very very strange indeed.

A good example of this weirdness is the humble electron. Without which, modern electronics (see!) would not function. But our humble sub atomic particle exhibits some very odd behaviour at the quantum level. It can become or is both a particle and a wave, depending on how its being tested and get this.....just watching, makes it do weird things.

In this very cute youtube video, called Dr. Quantum, featuring the famous "double slit" experiment. It is a fun watch, but I will guarantee that you will come away scratching your head. Give it a go!
