Schrodinger's Cat: A proton bouncing around inside a box will eventually contact on a detector and poison the milk a cat is drinking and kill the cat, but seeing as the rules of Quantum Mechanics say it can be in two places at once the cat is simultaneously alive and dead; simultaneously stood up and fallen down. There seems to be more than one way of explaining Scherdinger's Cat, i've only heard the one with the vial of cyanide. I am now simultaneously sat writing this and in the opposite corner of the room.
So how does Quantum Mechanics affect fell running? Well for a start Tom Addison didn't win Dunnerdale because i reached each checkpoint 1 picosecond apart and crossed the line finishing the course in a total time of 5 picoseconds. Most importantly though i am simultaneously a senior member and a master.
