It was June 7, 1925, that Werner Heisenberg left for the North Sea island of Helgoland wanting to find some rest after a bad attack of hay fever. It was one of these nights that Heisenberg ‘invented’ modern quantum mechanics. He wrote later in his book ‘Der Teil und das Ganze’: “It was about three o’clock at night when the final result of the calculation lay before me. At first I was deeply shaken. I was so excited that I could not think of sleep. So I left the house and awaited the sunrise on the top of a rock.”
