‘Doxiadis invites us into the universe of Number Theory, he gives us a glimpse of what the mathematical profession and community during the first decades of the 20th century was like and introduces us to fascinating persons, such as the mathematicians Hardy, Ramanujan, Turing and Godel. Above all, he introduces us to the subterranean, psychological world of mathematical thought and creativity, in a world where obsession and passion (like those characterizing Uncle Petros) go out of limits’.
