This is a most remarkable book from many points of view. Using the matter-antimatter asymmetry in the universe as a central theme, it tracks the reasoning behind the essential ideas comprising the standard model of particle physics, its shortcomings, and its impact on our knowledge of the cosmos. And it does all this without a single equation, not even a Greek letter. This asymmetry accounts for our very existence, and Quinn and Nir have been in the thick of the theoretical developments.
