heard this joke just now, thought it was kinda smart so i decided to post it here..

(background info: Heisenberg's Uncertainty Principal :- it is impossible to know both the position and momentum of a particle above a certain accuracy at the same time, and is true for everything)

one day, there was a physicist driving on the highway...

so fast was he that he was stopped by a police officer, and th following conversation ensued:

police : stop there, mate
physicist : what seems to be the problem, officer?
police : do you have any idea how fast you're going?
physicist : no, but i know where am! lol!

get it?
