Of all modern scientific theories, quantum theory has perhaps done more than any other to change the way we think about basic structure of the universe. This clear and accessible introduction covers quantum physics in theory and in practice, and explains why it has become known not just as a theory, but as a revolution.

From quarks to computing, this introduction covers very element of the quantum world in clear and accessible language. Alastair Rae draws on a wealth of expertise to explain just what a fascinating field quantum physics is - not simply a maze of technical jargon and philosophical ideas, but a reality which affects our daily lives.

Alastair Rae is editor of The European Journal of Physics and was until his recent retirement, Reader in Quantum Physics at the University of Birmingham. His Quantum Mechanics, now in its second edition, has become a standard undergraduate text on the subject, and his book on the philosophical implications of quantum theory, Quantum Physics: Illusion or Reality?, is in its fourth edition and has been translated into six different languages.
