Quantum mechanics is a mathematical theory describing the behaviour of objects roughly 10 billion times smaller than a typical person. Quantum particles move from one point to another as waves, but when detected they always appear as discrete lumps of matter or particles. There is no counterpart to this behaviour in our physical world, and you cannot rely on every-day experience to come up with an intuitive idea of how these objects move. The thoroughly unpredictable nature of the subject at hand led some older physicists in the 1920’s to dispute vigorously, at least initially, the conclusions put forward by younger colleagues, notably Heisenberg. This debate provoked Einstein’s most famous complaint, that “God does not play dice with the universe.” Scientists feel uncomfortable with unpredictability. In the end, the old guard conceded very quickly that the new quantum mechanics was the wave of the future. All physicists today agreed that to understand the study of the basic elements of quantum mechanics it is essential to grasp the behaviour of still more complicated quantum systems. Quantum mechanics, therefore, is the branch of physics that attempts to understand matter at the atomic level. It is the study of extremely small particles/waves and how they function. T he field of quantum mechanics discovered four fundamental forces that control our universe: (1) electromagnetic, caused by photons; (2) nuclear strong or gluons; and (3) nuclear weak or the //W// and the //Z// bosons. The strength of these forces is  measured by the  coupling constant, denoted by //g//, which determines the strength of an interaction.
