Fact of the month: Quantum entanglement was proposed in 1935, in the EPR (Einstein, Podolsky, Rosen) paradox. Quantum entanglement is one of my favourite phenomenons. Quantum entanglement is basically when one particle in a pair of 'entangled' particles changes its quantum state. This may not seem very significant in a stand-alone statement, but it is really quite fascinating when you know some of the basics about photons and various aspects of quantum mechanics. The idea of faster than light communication between entangled particles was considered to make no sense by Albert Einstein, Boris Podolsky, and Nathan Rosen, as the speed of light (299,792,458 m/s) was considered to be the highest speed possible to achieve. Even newly discovered gravitational waves travel at the speed of light (it takes light 8 minutes for light to travel to Earth from the sun, so if the sun was suddenly taken out of its position, the Earth would not change it orbit until 8 minutes after the sun was...

Fact of the month: 99.9999999999999% of a hydrogen atom is nothing. This means that everything around you is mostly nothing. The chair you are sitting on, the device you are reading this post on. It is mostly nothing. A reasonable size proportion for this is that if an atom was the size of our planet, the nucleus has a diameter of Manhattan. This is the fact of the month because I think that this fact is mind blowing (not literally). (above) A hydrogen atom.
