# Abstract

Starting with Erwin Schrödinger’s cat paradox the two-part Mini lecture “Quantum Mechanics” introduces to the central, quantum mechanical principles for the analysis of microscopic elementary particles: Max Planck’s black body radiation theory, Einstein’s photoelectric effect, Bohr's atomic model and the Heisenberg’s matrix mechanics and uncertainty principle. Part two of the Mini Lecture "Quantum Mechanics" discusses Bohr's atomic model and the Heisenberg Uncertainty Principle and highlights the validity of both theorems for present-day quantum physics research.
