Crucial to most research in physics, as well as leading to the development of inventions such as the transistor and the laser, quantum mechanics approaches its centenary with an impressive record.However, the field has also long been the subject of ongoing debates about the foundations and interpretation of the theory, referred to as the quantum controversy.This Oxford Handbook explores the contrasts at the heart of the history and development of quantum physics, as well as providing a fascinating examination of the future potential of the subject to influence new discoveries and advances in quantum information and computing, among other fields.Drawing on the wide-ranging expertise of several contributors working across physics, history, and philosophy, this engaging introduction is an essential guide for all those interested in the history of scientific controversies and history of quantum physics.
