Heisenberg's Uncertainty Principle


Werner Heisenberg developed this principle in regards to quantum mechanics. In a very simple overview it explains why you can NOT accurately measure a particles velocity and locations simultaneously.

Since we know that the speed of light (which are just packets of photons) to be #3.0#x#10^8 m/s# and the speed of light is constant, meaning there is no acceleration or deceleration of light, we cannot know the exact location of the photon.

Knowing one means you can not know the other.
