There are two parallel narrative streams in About Time. One relates how our human experience of time has evolved from a Palaeolithic bone etched with lunar phases through sundials, clocks, electric telegraph and the invention of time zones to make railway timetables workable. The other unfolds our scientific understanding of time; essentially a history of cosmology from Ptolemy and the Copernican revolution, through Newton's absolute time, its overthrow by relativity, the short-comings of the standard inflationary hot big bang and some alternatives: the multiverse and ekpyrotic universe models.

The central thesis of Frank is that these two streams are inextricably coupled, that our science of time has been moulded by social time and vice versa. The links between the two stories are artfully made so although I was sceptical about the author's approach when I opened the book, by the end I felt he had made a prima facie case.

About Time is not as comprehensive as I would have liked. Frank tells us nothing about how time was viewed by philosophers (e.g., Aristotle, Kant, Mach), nor does he stray from the western tradition. There is nothing about atomic clocks, nor about why we now use UTC, which distances us from the age-old astronomical measure of time by the Earth's rotation. Nor is there anything about time travel. Frank is at his best when he discusses how modern cosmology has developed. His broad-brush exposition is uncluttered by technical details, yet he introduces critical and difficult arguments, such as those about entropy and the Universe, easily and painlessly.

About Time is not the last word on time, but it is a novel, popular level approach, and for anyone wanting to explore cosmology for the first time, this would be a good place to start.
