The twentieth century was defined by physics. From the minds of the world's leading physicists there flowed a river of ideas that would transport mankind to the pinnacle of wonderment and to the very depths of human despair. This was a century that began with the certainties of absolute knowledge and ended with the knowledge of absolute uncertainty. It was a century in which physicists developed weapons with the capacity to destroy our reality, whilst at the same time denying us the possibility that we can ever properly comprehend it.

Almost everything we think we know about the nature of our world comes from one theory of physics. This theory was discovered and refined in the first thirty years of the twentieth century and went on to become quite simply the most successful theory of physics ever devised. Its concepts underpin much of the twenty-first century technology that we have learned to take for granted. But its success has come at a price, for it has at the same time completely undermined our ability to make sense of the world at the level of its most fundamental constituents.

Rejecting the fundamental elements of uncertainty and chance implied by quantum theory, Albert Einstein once famously declared that 'God does not play dice'. Niels Bohr claimed that anybody who is not shocked by the theory has not understood it. The charismatic American physicist Richard Feynman went further: he claimed that nobody understands it.

This is quantum theory, and this book tells its story.

Jim Baggott presents a celebration of this wonderful yet wholly disconcerting theory, with a history told in forty episodes -- significant moments of truth or turning points in the theory's development. From its birth in the porcelain furnaces used to study black body radiation in 1900, to the promise of stimulating new quantum phenomena to be revealed by CERN's Large Hadron Collider over a hundred years later, this is the extraordinary story of the quantum world.

Jim Baggott, Freelance science writer

Jim Baggott is a freelance science writer. He was a lecturer in chemistry at the University of Reading but left to work with Shell International Petroleum Company and then as an independent business consultant and trainer. His many books include Origins: The Scientific Story of Creation (OUP, 2015), Higgs: The Invention and Discovery of the 'God Particle' (OUP, 2012),  and A Beginner's Guide to Reality (Penguin, 2005).

Review from previous edition: 'A highly original and engaging account of the most important theory in science.' - Jim Al-Khalili

`Jim Baggott's survey of the history of the emergence of the twentieth century's most enigmatic but successful theory is a delight to read. It is clear, accessible, engaging, informative, and thorough. It illuminates an important, revolutionary era of modern science and the varied personalities behind it.' - Peter Atkins

`[A] wonderful histiry of the scientists and ideas behind quantum mechanics...     The basic history behind the quantum revolution is well known, but no one has told it in quite such a compellingly human and thematically seamless way.' - Publishers Weekly

`Jim Baggott's inspired -- and inspiring -- idea of presenting the history of quantum physics in terms of 40 key moments works both an an introduction for the uninitiated and as a refresher for anyone who thinks they know the story. Even familiar stories come up fresh in these juxtapositions. Great to dip in to!' - John Gribbin

`an enjoyable addition to the overall quantum story' - Chemistry World

`A truly exceptional book' - CERN Courier

`An accessible and informative history' - Science magazine

`gripping story' - Flipside Magazine
