Einstein's Dreams - by Alan Lightman

This book was a present last Christmas. It is unlikely that I would have read it had I not received it as a gift, but I am glad that I did.

It is a set of short essays, each presented as if it were a dream experienced by Einstein. The theme is that each dream takes place in a different world/universe, where the nature of time is different from what we are used to. For example, in one universe, the degree of order [entropy] tends to increase, the reverse of what we expect; for instance, a broken object reassembles itself. In another universe, each person's perception of time was different; one individual may observe a woman as rushing by, whereas another observer may see her strolling slowly.

I found this quite easy to read, entertaining and thought provoking. Each dream is described very much in terms of the people and their experiences, which brings it to life. Recommended.
