German born theoretical physicist Werner Heisenberg (pictured below) is perhaps best known for his 1927 Uncertainty Principle.
Heisenberg's Uncertainty Principle states that determining the position and momentum of a particle necessarily contains errors the product of which cannot be less than the quantum constant h. These errors are negligible in general and on a human scale but become critical when studying very small things like atoms.
In other words ... the mere act of observing a thing, hits that thing with light particles (photons) and moves it; so by the time you actually see the thing, it has moved to somewhere else. (Damn!)
Please bear this in mind.
