Quantum Theory - The Coin Toss

In 1905 Einstein released his paper on relativity. By 1915 he developed that into general relativity. But the biggest and most amazing shift in our understanding of the world came with quantum theory. So I'm now going to try and whiz through quantum theory for you. And hopefully it's understandable. If not, I don't know, I've given it my best shot in the time available.
