Notes for Class Meeting 19: Uncertainty
... This concept can help us understand why energy states are quantized in the Bohr atom. Say we want to measure the energy of an atom to high precision. From the uncertainty principle, this will take some period of time. Consider two cases, one that meets the Bohr condition that each orbit contains an ...

... One of the easiest non-trivial examples of quantum probability is provided by independent addition of spins. The limit distribution is a non-commutative gaussian state. This has been proven by many previous papers e.g. [1], [2], [3]. The object of this paper is to calculate the distribution explicit ...

Schrödinger Equation
... The Schrödinger equation plays the role of Newton's laws and conservation of energy in classical mechanics - i.e., it predicts the future behavior of a dynamic system. It is a wave equation in terms of the wavefunction which predicts analytically and precisely the probability of events or outcome. T ...
