Dispensable February 2

This book is not uninteresting but I found it too "literary" (philosophical?) And not sufficiently rigorous scientifically:
- The rise in the time since the Big Bang until our time is a bit "longuette" ...
- Some Aneries (at best awkward) "cyanobacteria convert nitrogen oxygen" [or rather fix nitrogen and release oxygen in CO2?] (P132), "a fireball dug a deep furrow in s 'overwhelming "[ca do not dig a crater a groove, see the moon] (P134) ...
However, like the other books of the two brothers, ca reads rather well, but once we removed the coating, essentially stands on one A4 sheet; So rather take the book to the beach on vacation (if you're not afraid of ridicule!).
As against this, we would like one day they come out a book less "popularizer" and a little further scientifically (we always try the famous "Bogdanov equation," personally I have not seen yet). Of course, the physics of the big bang (and a fortiori before) is physically quite speculative so why not the speculations of Bogdanov ... But I have the unfortunate impression that the two brothers prefer to popularize and expound philosophically on a domain " open "(and go on TV!) rather than do research in the lab (or home) and publish in journals or participate in seminars. Their books are not translated into English (weird? Only can the French enjoy their lights?) And their latest publication in a scientific journal date almost 10 years and its relevance is still debated ... In short, gentlemen Bogdanov, I would ask you to work a little more seriously if you want me to put you 5 stars!
