"A pop science look at time travel technology, from Einstein to Ronald Mallett to present day experiments. Forget fiction: time travel is real.
"In "How to Build a Time Machine," Brian Clegg provides an understanding of what time is and how it can be manipulated. He explores the remarkable possibilities of real time travel that emerge from quantum entanglement, superlumina

For a book about the wonders of time travel, this one isn't very enthusiastic. The science-history is interesting enough, although if that is what you're after I recommend A Brief History Of Time and The Physics of the Impossible as the best bits here are already attributed to Hawking and Kaku. The trouble with pop science books like this--and it isn't Clegg's fault at all--is that I'm a fan of the genre. I already know about Young's double slit experiment, relativistic time at speeds approachin ...more

I am a science fiction writer that has written on wormholes and time travel. So I'm alwasys on the lookout for the the lastest research on time travel theory.

That is why Mr. Clegg's book was a great surprise for me and and an easy to read work on the basics or the reltavistic principles of the features involved with the traveling through spacetime.

His chapter on the story of Ronald Mallett and his research was an incredible chapter on the newest research on this exiting subject.

I get a lot of q

A lot of it is really technical, but very informative which leads me to wonder why Sheldon and Leonard (Big Bang Theory) are always waiting for time traveling selves to walk through the door? Being physicists they should know the rules about traveling to the past. Can't say much more without giving the plot away!

It seemed to me he was struggling to fill the pages. He repeats himself over and over again. Found it dull, often annoying. Nothing in there I hadn't already read somewhere else where it was presented in a more interesting way.

I considered giving this book four or five stars because I got a lot out of it and because I think Brian Clegg is a terrific science writer. But I just can't get past the problem of the title. This book will not help you to make a time machine. Just the opposite really. Although he never says so, the result of reading his book is clearly that given the laws of physics, time travel is impossible. This is clearly implied in his examples, for instance when he suggests you could time travel "if you ...more

Before beginning my review of this book I want to make it perfectly clear I have very little prior knowledge of quantum mechanics and physics that I used to inform my reading and that was my motivation to pick up Brian Clegg’s book. I love physics but hate math, which is a bad combination in the academic/practical world of physics. I do have the background of some college level physics, and that was enough for me to understand the concepts the way Clegg explains them in his book.

Unlike what the

No self-respecting science fiction writer would try to write without actually reading some science, and this is more ammunition for my speculation gun. Brian Clegg holds a physics degree from Cambridge University, and is the author of other popular books on physics such as Before the Big Bang and Armageddon Science. He does a good job of writing about some pretty heady stuff (quantum theory) without losing most of his readers. In contrast to most physicists, he also had the ability to communicat ...more

Time travel? That would free up my schedule for reading and give me the opportunity to get a better mortgage rate and fix that pesky arrest record. Though not a how-to, this absorbing title enjoyably discusses scientific topics ranging from the zeroth law of thermodynamics to the evolution of the calendar‚ all in relation to the concept of time. Clegg points out that memory is a one-way time machine‚ though I was hoping for a phone-booth-esque machine with buttons and levers. Reading his summary ...more

Time travel is a concept that is today more science fact than science fiction, but the key to understanding how this could become reality is the main question that Brian Clegg addresses in this rather interesting book. Clegg takes us on a journey that takes us from the very basic question of what is time all the way through the question of paradoxes. In the journey he examines the feasibility of time travel & the energy as well as physics behind the concept. He also describes just what it mi ...more

As a science fiction author I found this book an interesting read on the physics that can make time travel possible. It re-confirmed in my mind that the most likely means will be available in the distant future once there are starships that can make extended voyages at close to the speed of light, thus creating the time dilation Einstein's Theory of Relativity predicts. That would take the star traveler on a one-way trip into the future.

Other theoretical means for time travel such as passing thr
