Travels in Four Dimensions: The Enigmas of Space and Time Book

Very clear review of metaphysical problems involving space, time and infinity. It was a pleasure to read and I found many thought experiments I hadn't come across before - e.g. the splitting of a cone.

I especially feel I benefitted from some of the arguments in the end, one of which explained the idea of "Presentism" - that when you rewrite history textbooks, you have actually changed the past. A terribly foolish idea, but one that can be seen many times in recent history and even in the current political atmosphere.
