Jim Baggott, a scientist, writer, popularizer of science, in his book examines in detail the process of predicting and discovering a new particle - the Higgs boson, simultaneously covering such issues of fundamental physics as the structure of matter, the origin of mass and energy. The author explains that the importance of the discovery of the particle also lies in the fact that it proves the existence of the Higgs field, thanks to which massless particles acquire mass, which is a necessary condition for the emergence of matter. From the book you will learn about the development of physical theories, starting with the ancient concept of the atom, and the technical progress that made it possible to implement them, as well as the history of the discovery of elementary particles.
