Until recently, travelling through time seemed little more than fantasy. But quantum theory and particularly relativity open up ways to make time travel possible - and I still find it remarkable that no physical law prevents it.
How to Build a Time Machine explores our best understanding of time but really concentrates on how to manipulate it. There's the story of a time traveller's convention where no one turned up, and a tour through the remarkable possibilities of real time travel that emerge from quantum entanglement, superluminal speeds, neutron star cylinders and wormholes in space. There's even a physics professor who believes it's possible to build a working general relativity time machine on the desktop. I think it's just a fascinating subject.

It's a bit soon for reviews (except those sent through a time machine), but here's a couple of early comments:
Brian Clegg conjectures on the world of time and space travel and brings it all beautifully down to earth. Brilliant. - Johnny Ball
A solid overview of some of the quirkier corners of physics, with an entertaining connection to pop culture. - Kirkus Reviews
Well done, Brian, and congratulations on another release!
ReplyDeleteCongratulations Brian!
ReplyDeleteWhat a great idea for a title (and book)! Do you get your money back if it doesn't work (or accidentally tread on a butterfly if it does?)
No Clare, you don't get your money back, but you can go back in time and prevent yourself buying the book. Or can you?...
