The basic principle of quantum mechanics is that there is an [[uncertainty]] in the location of a subatomic particle until it is observed. This explains why the [[Second Law of Thermodynamics]] is always true, and why everyone declines with old age: disorder tends to overcome order. Quantum mechanics explains the discrete nature of small-scale interactions, [[wave-particle duality]], the [[uncertainty principle]], and [[quantum entanglement]]. Quantum mechanics forms the basis for our understanding of many phenomena, including [[chemical reaction]]s and [[radioactive decay]], and is used by all [[computer]]s and electronic devices today. No other theory explains all this. | The basic principle of quantum mechanics is that there is an [[uncertainty]] in the location of a subatomic particle until it is observed.
