YouTube Saturday - Schrödinger's Cat

Last Thursday would have been the 123rd birthday of Erwin Schrödinger, the great Austrian theoretical physicist (Click here to read our recent short biography of  Schrödinger). One of his most famous "thought experiments" is commonly known as  Schrödinger's cat - the famous illustration of the principle in quantum theory of superposition (matter behaving like particles and waves), proposed by Erwin Schrödinger in 1935. Schrödinger's cat serves to demonstrate the apparent conflict between what quantum theory tells us is true about the nature and behavior of matter on the microscopic level and what we observe to be true about the nature and behavior of matter on the macroscopic level. Below is a great video which attempts to explain the famous thought experiment. (Please ignore the presenter's dodgy haircut).
