Quantum Mechanics

A theory that describes the interactions of subatomic particles, combining several basic discoveries. These include Max Planck';s 1900 observation that energy is absorbed or radiated in discrete quantities, called quanta. Also Werner Heisenberg's 1927 uncertainty principle stating that we cannot know both the exact position and momentum of an electron or other particle at the same time. Interpretations of quantum theory imply that photons simultaneously take all possible paths (e.g., when bouncing off a mirror). Some paths cancel each other out. Remaining ambiguity in the path actually taken is resolved based on the conscious observation of an observer.
