Quantum Theory: Heisenberg's Uncertainty Principle

On Chance and Probability in a Necessarily Interconnected finite spherical Universe within a Non-Determined Infinite Space

At the same time that the wave properties of matter were discovered, two further discoveries were made that also profoundly influenced (and confused) the future evolution of modern physics.
Firstly, Werner Heisenberg developed the uncertainty principle which tells us that we (the observer) can never exactly know both the position and momentum of a particle. As every observation requires an energy exchange (photon) to create the observed 'data', some energy (wave) state of the observed object has to be altered. Thus the observation has a discrete effect on what we measure. i.e. We change the experiment by observing it! (A large part of their problem though was to continue to assume the existence of discrete particles and thus to try to exactly locate both their position and motion, which is impossible as there is no discrete particle!)
Further, because both the observed position and momentum of the particle can never be exactly known, theorists were left trying to determine the probability of where, for example, the 'particle' would be observed.
