What is mass ? It seems a naïve question. We all experience it, under the effect of gravity as weight. Mass is surely just the amount of matter in things. But what is the fundamental nature of matter and why does it have the property of mass ? The answer is far from simple, and it has remained elusive for centuries. From Greek ideas of indivisible atoms to quantum theory, colour charge, and the Higgs field, Jim Baggott takes us on a compelling journey : the search to understand the nature of matter. In the company of some of the worlds greatest scientists, we travel deeper and deeper into the stuff of the Universe. By the end of the book, we still dont have all the answers - but thats what makes the quest so compelling.

Quantum field theory - Wikipedia Quantum field theory is the result of the combination of classical field theory, quantum mechanics, and special relativity.: xi A brief overview of these theoretical precursors is in order. The earliest successful classical field theory is one that emerged from Newton's law of universal gravitation, despite the complete absence of the concept of fields from his 1687 treatise Philosophiæ
