Speaking of making electrons stop, I'm sure most of us know what the Heisenberg uncertainty principle is*. Well, whilst my friend was driving himself and I home one day, he was pulled over for speeding. The officer pointed back down the road and asked him "Do you know how fast you were going back at that intersection?"
I responded before my friend could by saying rather loudly "NOPE! And neither do you, since you saw us!"
... I was told to be quiet or he'd take me in for impeding justice and my friend talked his way out of the ticket.
Eh, I guess it was because of my friend's demeanor and the fact that he was the one driving. In retrospect it was pretty stupid, also a very fun memory.
Werner Heisenberg is driving on a highway near Munich when he is pulled over for speeding. "Do you know how fast you were going?" says the police officer. "No", says Heisenberg, "but I do know where I am."
I also like this joke:
A student boards a train in Manhattan. As he sits down, he recognises Albert Einstein sitting across from him. "Excuse me, Professor Einstein", he says, "But does Boston stop at this train?"
And what about Turing complete imperative languages? Unless Albartoss was talking about languages that cannot support the concepts of branching and repetition at all, as opposed to ones that offer different ways to deal with them.
