This slim book has the appealing premise of looking at the basics of space physics, from gravity through rocket science to the nature of a vacuum, by using examples from 'well-constructed science fiction'. We are not talking about the typical movie or lightweight SF novel here, but rather the work of 'hard' science writers - most notably Arthur C. Clarke and Andy Weir (not to mention astronaut-turned-author Chris Hadfield). Andrew May uses extensive quotes from such authors showing how the real physics of getting into space and living away from the Earth is significantly different from the Hollywood version. Things start off with Jules Verne and his two Moon novels. May admits that Verne had to wildly fudge things over getting into space, using a cannon that would have mashed the occupants, but apart from that, Verne did his best to stick to the science as much as was known at the time, for example even putting in an equation giving a rough calculation for escape veloci...
