effects : super/subradiance, Interaction of light with molecules.
Quantum physics is a
catch-all term for the ideas, devices and technologies made possible by the
development of quantum mechanics in the early part of the 20th century. This
note concentrates on the ideas behind quantum mechanics itself, but the broader
field of quantum physics encompasses everything from the science of electronic
devices and lasers to the philosophical mysteries of quantum measurement
theory.

This book is written for anybody who is curious about nature and
motion. It covers the following topics: Minimum action: quantum theory for
poets, Light: the strange consequences of the quantum of action, Motion of
matter: beyond classical physics, The quantum description of matter and its
motion, Permutation of particles, Rotations and statistics: visualising spin,
Superpositions and probabilities, quantum theory without ideology, Colours and
other interactions between light and matter and Quantum physics in a
nutshell.
