I can confess it: I became an astronomer Because of this book and the CORRESPONDING TV series, and I do not regret that. I asked this to be my birthday present When I was 10 or 11, It was 1600 pesetas (at expensive book at this time), and I read it several times. Since them I feel the emotion of thesis pages, and Their strength. When I read this again, I can not avoid to "float" by the great feeling. A must for anybody who wants to understand this world.
