Second Adar – The Month of Quantum Physics

Today is Rosh Chodesh Adar Bet – the New Moon and the beginning of the second month of Adar.  If we ever to have a month commemorating Quantum Physics, there would be no more appropriate month for that than the second month of Adar – Adar Bet.  A state of superposition is a physical state unique to quantum theory.  In classical physics (such as Newtonian mechanics or thermodynamics) a physical system is either in a state A or a state B. Only in quantum physics a system can be in a blended state C which is a linear superposition of states A and B. For example, if the spin of an electron can be Up or Down.  However, an electron can be in a blurred state of superposition of states Up and Down, which [...]
