My heart is really torn. On the one hand, the first three short stories were amazing. I learnt so many interesting things, things that are somewhat related to science, I learnt about the life of interesting mathematicians and their quirks. It was great! But then the second half of the book turns more... imaginative and speculative, in a way that I did not really like. Speculating in crude terms about the sexual behaviour of certain scientists was not in line with the first half of the book, and its contrast was therefore more jarring. What I liked about the first three stories was how non-fictional they were, and you could tell that the second half of the book was so blatantly made up. I was really disappointed. But yes, I would definitely recommend that people read the first half of the book. It is really worth it.
