I find it interesting that the two biggest QM breakthroughs, by Heisenberg and Schrodinger, were both made while on holiday.

I'm reminded of another revolutionary innovation made under such circumstances: the penning of Frankenstein by Mary W. Shelley. It was written in Geneva, but was inspired by German ghost stories, visits to sites in Germany (such as the town near Frankenstein Castle), and current topics in science and pseudo-science. Furthermore, climateology and geology played a role: the party were hunkered down in Byron's place in Geneva during the year without a summer, due mainly to the 1815 eruption of Mount Tambora, which caused a "volcanic winter".
