tried to explain how classical mechanics emerges from quantum mechanics. Classical mechanics is about movement and change, while the strong empha-sis on stationary states in traditional quantum courses makes the quantum world seem static and irreconcilably different from the world of every-day experience and intuition.

That theory is known as quantum mechanics, and it is now the basic framework for understanding atomic, nuclear, and subnuclear physics, as well as condensed-matter (or ”solid-state”) physics.

The whole of quantum mechanics can be expressed in terms of a small set of postulates. When their consequences are developed, they embrace the behaviour of all known forms of matter, including the molecules, atoms, and electrons that will be at the centre of our attention in this book. This chapter
Download PDF files of the lecture notes for Quantum Physics I, a physics course at MIT. The notes cover basic concepts, one-dimensional potentials, scattering, angular momentum, and central potentials.
A PDF document with notes on quantum mechanics, covering topics such as probability amplitudes, operators, wave mechanics, oscillators, transformations, and perturbation theory. The notes are based on the lectures by F.H.L. Essler at the Rudolf Peierls Centre for Theoretical Physics.

Oct 5, 2012 · Quantum mechanics has played an important role in photonics, quantum electronics, and micro-electronics. But many more emerging technologies require the understanding of quantum mechanics; and hence, it is important that scientists and engineers understand quantum mechanics better. One area is nano-technologies due to the recent advent of nano-
