From the title to the illustrations (Sir Isaac comes in like a wrecking ball on the cover, lest the title prove too subtle), Freistetter maintains a consistent sense of humor, something Newton himself might prove incapable of appreciating. In keeping with the person-first nature of the book, there are no technical illustrations, no equations; as Freistetter (himself an astronomy teacher) points out, there are thousands of other studies of the man and his work for further study.
The book keeps things simple, with brief explanations of theories interspersed with examples of full-on dick moves, a 'Real Natural Philosophers of Cambridge' drama. Like 'reality' TV, some disses of Newton feel edited, heightened to provide conflict; others simply have to be seen in light of a different time, different sensibilities. That the man was brilliant is unquestionable; that he acted like a bored, petulant child is equally, cringingly, on display.
However, I didn't come away convinced of the central posit that Newton's prickly nature helped enable his discoveries, any more than being English, Christian, and a genius helped. Like the studies of political or industry leaders as having psychopathic tendencies, it seems almost by definition that an ego-maniacal, tortured soul could prove successful in self-promotion, with a sense of morality that others rightly see as monstrous; at least Newton could back it up with real insights and inventions.
