Today, at my Cryptology class, one of the students was giving a lecture on Quantum Cryptology. He gave a remedial discussion on Quantum Mechanics. Seems there's a certain Heisenburg Uncertainty Principle which basically states that you can't know both the speed and position of something with any degree of certainty. To which I replied, "I'll have to use that on my next speeding ticket... How could he know I was both going 88 AND that it was me???"
