Heisenberg Uncertainty Principle
From Encyclopedia Dramatica
Werner Heisenberg was a German physicist who one day decided that in order to measure one quantity, you have to increase the uncertainty of a related quantity. For example, you can't measure the momentum of a immobile object.
The Heisenberg Uncertainty principle itself states that you cannot know both the velocity of a particle and its position. The more accurately you get a fix on one, the less accurate your other information becomes' It is therefore something to do with quantum mechanics.
In today's world, Internets Know-It-Alls are now using it to describe the relation between observation and result, most often with the pseudointellectual claim that 'observing something changes the outcome'. This is, in fact, untrue, because no matter how long you look at him, Nathan Sheets will never be pretty.
