"Lovers" implies perhaps a dose of impartiality but this book from a collection of "love" theme addresses a wide variety of scientific topics. D "Abstraction," "Academy of Sciences", "accretion" ... until "Xenon", "Thomas Young," "Zoology"; everyone will find at least one subject of interest. "Dinosaurs" is an excellent summary of the subject and perhaps a gateway to the dictionary that wants all audiences. Scientists, however, find their account there because we can not perfectly control all subjects (atom, evolution, nuclear physics, biology, astronomy, ecology ...) and each definition is helpful although synthetic. Mini biographies of the most famous men of science (Newton, Darwin, Lavoisier ...) are inserted in alphabetical order as well as concepts (God, chance, doubt, truth ...) and synthetic definitions historical ("Star", "wave", "cell" ...). A dictionary both passionate and erudite.
