Connoisseur and passionate astrophysics, I did not learn much by reading this book written in the late 80s I wanted above all to discover the author, I had heard the most good, and that had happened to follow 2-3 times in television documentaries. Well I was wrong! His description of the first moments of the Big Bang is phenomenal and chapters that compose it form an extension masterpiece unto itself. Using powers of 10 to all paragraphs gave me the kind of thrill I love astrophysics when insane dimensions tickle our ability to imagine. All this knowing that the book was written even though Hubble was not entered service! In short I gets off a max.
However it is with great disappointment that I read the last part of the book, where the author seemed to change their attitude. It suddenly becomes milder, both in substance and in form. Exit prudence and scientific reserve. Even the language used seemed very ill-chosen blow and borrowing a subjective meaning and connotations that do not fit the objective scientific analysis he has shown in previous sections. I noted some errors when after asking a question, he raises only 2 or 3 possible answers, skipping (voluntarily or not) other possibilities that seem obvious. Too bad.
Anyway I highly recommend the book, and I reread several times.
