Quantum Mechanics

DeBroglie provided an explanation for the stability of the Hydrogen atom’s electron orbitals using standing waves.  DeBroglie’s hypothesis was that all matter has wave properties.  The wave properties of matter have been observed in electron interference experiments and are the principle of operation of the electron microscope.  Heisenberg’s Uncertainty principle limits the accuracy of simultaneous measurements of position and momentum of a particle.  Quantum mechanics predicts the behavior of subatomic particles using probability.
