In 1900, Max Planck theorized that energy comes in discrete bundles called "quanta." Einstein's research later reinforced this idea. At the atomic scale, according to Werner Heisenberg's famous uncertainty principle, every measurement changes its object. Thus quantum-scale events can only be described in terms of probabilities, and electrons display the characteristics of both particles and waves.
