Heinsenberg's Uncertainty Principle states that and electron is a particle that can be described in terms of waves. We can know the path an electron takes as it moves through space, or we can know where it is in a given instant. We cannot know both; any attempt to measure one will unavoidably disturb the other.
Pauli's Exclusion Principle states that the moment you determine the spin of a certain subatomic particle, its sister particle, no matter the distance, will immediately begin spinning in the opposite direction at the same rate.
