This book is an exciting thriller where the characters are hunter-scientists and elusive neutrinos. The tiny particles we call neutrinos answer global questions: why is it so difficult to detect antimatter, how stars explode into supernovae, what happened in the universe in the first seconds of its life, and even what happens in the bowels of our planet? The book of the famous astrophysicist Ray Jayavardhan is devoted not only to the history of neutrino research.
