Time: A Graphic Guide

Craig Callander

Is time a fourth dimension similar to space, or does it flow in some sense? And if it flows, does it make sense to say how fast? Does the future exist? Is time travel possible? Why does time seem to pass in only one direction? These questions and others are among the deepest and most subtle that one can ask, but Introducing Time presents them – many for the first time – in an easily accessible, lucid, and engaging manner, wittily illustrated by Ralph Edney.
