دانلود کتاب Just Six Numbers: The Deep Forces that Shape the Universe

This is a rather balanced account about the stable or expanding universe or multiverse issue. Rees is the Royal Astronomer of England or something so he is a bit cautious about cosmological speculations, which is, i think, a good thing. It's upsetting when scientists go rambling all over the place about matters about which they have zero information. I thoroughly enjoyed his explanations about dark matter, the inflationary universe, gravity, and the mechanism of converting hydrogen to helium and deuterium. I had been reading about the importance of that but until Rees's explanation i didn't know why it was important or how it happened. In the end it would seem that we are almost unbelievably fortunate to be alive in This Universe. And i think that is a good message, "be thankful for the life you have, even if you don't understand it."
