If you were looking for someone who could explain all the ins and outs and forwards and sideways of time travel, you’d be hard-pressed to find a better writer than James Gleick. He’s previously tackled topics like chaos theory and the life and work of Richard Feynman. So a history of the idea of time travel seems like a natural subject for him to present to the average intelligent reader.
Gleick starts by taking us back in time to when H.G. Wells was penning “The Time Machine”. He discusses early drafts of the novel, and mentions some of the problems that reviewers noted – what happens if solid objects are in the space the Traveler is passing through, for one, and how do you account for the fact that the earth is both rotating and moving through space (the latter is one that time travelers always seem to forget).
From there, he moves forward in time through physicists treating time mathematically as a dimension, philosophers grappling with the concept of time, and even lexicographers trying to simply come up with a definition of the term that doesn’t wind up spinning in circles: “Time is what clocks measure”; “A clock is a device for measuring the passage of time.”[1]
