"Mathematicians look for elegance in a new equation; when they find it they realize that it is poetry that has been found. One would not say that ∆E∆≥h/4π. (this is Heisenberg’s Uncertainty Principle) is “art” without being insulting. But it is poetry, and it is highly useful." [full text here]
Heisenberg’s Uncertainty Principle is a theory that basically states that position and momentum of a particle cannot be simultaneously known. In other words, the fact that you are able to observe something already influences your findings and renders the result of observation useless. To demonstrate his theory, Heisenberg said we should imagine a box with has a kitten inside; as long as the box is closed we will not know what is happening inside it and the kitten can be only potentially dead or alive.
