There are two slightly different ways to derive this and we will study both ways. Caves, defense of the standard quantum limit for freemass position. Download it once and read it on your kindle device, pc, phones or tablets. It says that the more precisely you measure the position of a particle, the less precisely you can know. Heisenberg utilized such an observer effect at the quantum level see below as a. 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.
