I loved this book. It is a work of popular science, (albeit at the top end of popular science) which seeks to make the frighteningly complicated and esoteric world of modern cosmology accessible to the intelligent lay reader. The author, Anil Ananthaswamy, does this by exploring three parallel themes, the physics, the places in which the experiments are being undertaken, and the physicists, engineers and technicians doing the work. Thus we visit optical astonomers in Hawaii, Chile and California, radio astronomers in South Africa, frighteningly complex particle detectors in Siberia and Antarctica and the Large Hadron Colider in Europe.
The people who work on these are a diverse, but driven, and frequently hard drinking band of theorists, innovative implementers and hardy observers. Together they dream up, build and operate giant telescopes, submarine and sub-ice particle detectors, radio arrays, and subterranean race tracks designed to obliterate the building blocks of matter.
The author uses these people and places to give an understanding of the major theories and challenges of modern cosmology, the search for dark matter and dark energy, string theory, super symmetry, the multiverse and the anthropic principle.
He doesn't always succeed in giving a full understanding of the subjects, but that is entirely understandable given the mind blowing nature of his source material. If the lay reader cannot understand all the rules of the game, Ananthaswamy at least gives an understanding of its basic purpose and the major strategies being employed.
The three pronged approach of the book works well, and is particularly successful in the chapter about the Large Hadron Collider. Everything about this amazing experiment is awe inspiring, its size, the technical expertise necessary to build it, the speeds, temperatures and energies it employs, the audacity of the experiments, and the fundamental things it could tell us about the universe(s) just left me completely and utterly gobsmacked.
To learn something about what is going on in modern physics, but also to find out about the amazing people behind it, read this book.
Very highly recommended.
