This book acts as a perfect introduction to not just the world of antimatter, but also something of particle physics.
Close begins by discussing the legend of antimatter. A bizarre group of particles, often finding their way into Science Fiction, yet antimatter is real, it can exist, despite being annihilated on contact with matter. Close debunks what is false, and introduces the reader to the reality of antimatter, and the accompanying particle physics. A far from simple feat, having read several books previously which left me puzzled by Feynman diagrams, or simply what the particles are, Close takes a slower, gentler approach and succeeds in making the whole subject easily accessible.
The appendixes are very interesting too, offering some deeper insights into Antimatter, although some mathematical understanding may be necessary and can be left.
