Introducing Time presents you with the questions that have perplexed human beings for centuries - Is time merely in the head? When does time end and is time travel possible?
Craig Callender and Ralph Edney attempt to tackle these questions (and more) in a readable and exciting look at the science and history of time.
It begins with the 5th century philosopher Augustine of Hippo's question "What is time?" and then takes us on a tour of time hypotheses up until Stephen Hawking's theories in the 21st century.
The book covers everything from time keeping devices and biological clocks to the ideas of Newtonian time, the fourth dimension, space-time, Einstein's relativity, wormholes, the law of entropy and statistical mechanics.
Along the way, the authors discuss what might happen if we were to travel back in time and kill our younger selves - would we still exist, or would we vanish? Could we stop Abraham Lincoln's murder or assassinate Hitler? What would happen if time went into reverse, and is that even possible?
The authors also make mention of sci-fi films and books such as the Terminator, Back to the Future and Philip K. Dick's Counter-Clock World, where they discuss if the plots of these stories are logically possible.
If you have ever wondered about things like these, then this book will present you with the most up to date ideas on these topics within the scientific community. Black and white cartoons and drawings illustrate every page, which makes these topics easily digestible.
This is probably the most accessible book on this subject for the layman. It presents fascinating, mind boggling and often paradoxical ideas such as a 'never ending finite space' and the idea that the universe sprang into existence 5 seconds ago in a way that anyone could understand.
A terrific book, and one of the best in the 'Introducing' series. Thoroughly recommended!
