The Big Bang : it's real AND comprehensible!
It is an extraordinary fact that we, a small scrap of biological matter inhabiting a negligible space in an obscure corner of the Universe and having come into existence a mere eyeblink ago, we can comprehend the whole Universe right from its very beginning!Steven Weinberg (1979 Physics Nobel prizewinner) has written a gem of a little book first published in 1977, a classic that deserves to be on every shelf and that everyone should read. He explains, using only school arithmetic, precisely what happened at the Big Bang, and precisely how we know it.In a mere 50,000 words or so, a little book, Weinberg shows how the longstanding belief in an eternal Universe was overturned. This old belief underpins Newtonian (and Aristotelian) physics, and was universally believed until about 1950. But the discovery by Penzias & Wilson of the Cosmic Microwave Background in 1965 dramatically overturned this consensus and replaced it with a Universe finite in both time and space.Of course, Penzias & Wilson's observation of the CMB was only the final piece in the puzzle of the new cosmology. The expansion of the Universe first proposed by Hubble with his explanation of stellar redshift in 1929 (together with Penrose & Hawking's gravitational singularity theorem in 1970), the understanding of stellar nucleosynthesis summarised by Hoyle, Fowler and the Burbridges in 1957, the observation of the H/He ratio in the Universe by Suess & Urey in 1956, and the theoretical prediction of this first suggested by the famous Alpher Bethe Gamow paper of 1948 which also made very clear that the early Universe had to be hot, all made an environment in which the importance of the 1965 CMB observation could be immediately recognised.Subsequent discoveries and developments have served only to underline this new consensus; for example, the strictly black body nature of the CMB was established in 1990 at extraordinary accuracy by the COBE ("Cosmic Background Explorer") satellite. There are many profound problems remaining in cosmology, but however it is understood it is clear that our Universe had a beginning in time.In my opinion, Weinberg's book is a tour de force of an elegantly simple explanation of the biggest fact underlying who we are. And he doesn't tell us fairy stories : he doesn't oversimplify. This is really the way things are, and you can understand it too! Buy the book!

Best 3 minutes ever explained
It had to be a winner after watching Steven on world science festival on YouTube. It didn’t disappoint. Such an important time of the world’s existence and he explains it in simple detail , both factual and conceptual. A must read if this is the time you are looking to explore.

Good
Weinberg is at home both in cosmology and in elementary particles, so i just trust him that he made a very good selection of what topics to present. His writing style is similar to what he radiates on photos: composed, not exuberant. His sentences are all clear and simple.In the preface Weinberg writes that he intends his book for people who do not speak his language, meaning he bans formulas (but not numbers of temperatures, particle proportions etc.) into mathematical supplements, and shows some pictures and graphics but only few x-y-plots with explicite numbers. As a consequence the book gets longer, and the information gets more diluted.I really liked the tables, mathematical supplements, and also the afterword (written in 1993) at the end of the book, but was a bit bored in the main part of the book (150 pages), because the pace was too slow for me.To note: Physical quantities are given in cgs units, and large numbers are first given in long words, and then sometimes in the much shorter power of ten notation; e. g. on page 101: fifteen hundred thousand million degrees Kelvin (1.5x10^12 ° K).

true scholarship
when you here it all from the horses mouth as it were then it all becomes real - even if the material is all fantastically unreal! I mean - the first 3 minutes of the universe ! extraordinary concepts dealt with in straightforward understandable language...true scholarship..

Nicely structured with just enough detail/repetition to allow non-scientists with maths and physics at A-Level etc to follow. This is not for those without any background knowledge though. Or close-minded creationists who choose to ignore what science can observe!
