Electron filmed for the first time

It is now possible to see a movie of an electron. This movie shows how an electron rides on a light wave after just having been pulled away from an atom. This is the first time an electron has ever been filmed. With the aid of newly developed technology for generating short pulses from intense laser light, which is needed in order to capture these rapid events, scientists have moreover succeeded in guiding the motion of the electron so that they can capture a collision between an electron and an atom on film. Scientists can now study how electrons behave when they collide and also hope to find out more about what happens with the rest of the atom when an inner electron leaves it, for instance how and when the other electrons fill in the gap that is created.

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!
