Jochen heisenberg born 1939, german physicist, son of werner heisenberg. He is best known as a founder of quantum mechanics, the new physics of the atomic world, and especially for the uncertainty principle in quantum. Historically, the uncertainty principle has been confused with a related effect in physics, called the observer effect, which notes that measurements of certain systems cannot be made without affecting the system, that is, without changing something in a system. And here we have heisenberg, vernon heisenberg on the right, and here we have a statement of the heisenberg uncertainty principle.
The heisenberg uncertainty principle is a physical law that forms part of quantum mechanics. The second is more elegant and leads to fun things such as coherent states. B0 at the same time then we would have a simultaneous eigenstate. There are two slightly different ways to derive this and we will study both ways.
