Most theories in classical physics can be derived from quantum mechanics as an approximation valid at large (macroscopic) scale. Quantum mechanics differs from classical physics in that energy, momentum, angular momentum, and other quantities of a bound system are restricted to discrete values (quantization), objects have characteristics of both particles and waves ([[wave–particle duality]]), and there are limits to how accurately the value of a physical quantity can be predicted prior to its measurement, given a complete set of initial conditions (the uncertainty principle). ##### ^dataviews > [!dataview]+ Related unlinked notes > > No results to show for list query. > [!dataview]- Other unlinked mentions > > - [[notes - Metaphysics of Meditation]] > - [[video - A brief history of quantom mechanics]] > - [[classical mechanics]] > - [[cosmological constant]] > - [[quantum entanglement]] > - [[the Big Bang]]
