The Boring World of Niels Bohr
Physicists have been under surveillance by the US government, to sometimes hilarious results. During World War II, Niels Bohr (and his son) visited Washington D.C., where they were under secret surveillance. The following declassified report confirms the standard suspicion of theoretical quantum physicists.
I type here the relevant part of the report on Niels Bohr:
Both the father and son appear to be extremely absent-minded individuals, engrossed in themselves, and go about paying little attention to any external influences. As they did a great deal of walking, this Agent had occasion to spend considerable time behind them and observe that it was rare when either of them paid much attention to stop lights or signs, but proceeded on their way much the same as if they were walking in the woods. On one occasion, subjects proceeded across a busy intersection against the red light in a diagonal fashion, taking the longest route possible and one of greatest danger. The resourceful work of Agent Maiers in blocking out one half of the stream of automobile traffic with his car prevented their possibly incurring serious injury in this instance.
In conclusion, yes, quantum physicists are very dangerous, but to themselves.
