Time travel is a common theme in science fiction, providing authors an opportunity to explore multiple future scenarios and the possible consequences of moving back and forth in time. In this book, the author, an MIT professor, tells of a graduate lab assistant who discovers that an apparatus he has built for quantum research travels into the future every time he activates it. Moreover, it takes anything connected to it along and each jump is exponentially further into the future. Unfortunately, not much is made of the possible impact of this travel (although in one future the student discovers that someone else has taken credit for his "discovery") and the imagined futures are dreadfully dull. The protagonist spends way too much time in a future where religion has become accepted as science, including at MIT. Haldeman fails to use his MIT connections to to explore the quantum physics that could theoretically make time travel possible.

I started skimming the book after several chapters just to get through it faster and almost stopped reading altogether more than once. Fairly unimaginative. The protagonist is annoying and self-righteous. His "adventures" are run of the mill at best. I expected some humor based on the book's description and title, but the only thing you'll laugh at is the idea that someone actually bothered to publish this book.

    Great idea, wonderful imagination

    It starts with a simple event in a non-descript laboratory and leads to one of the greatest adventures imaginable. I won't deny it - Joe Haldeman is one of my favorite writers, so I may be more than biased, but this is a great 'what if?' idea explained with a little physics and fleshed out with a wonderfully imaginative story that leads, literally, to the end of time. I can't recommend it enough.

    MIT laboratory assistant Matthew invents the calibrator, a gizmo that enables a person to travel forward in time however, there is no going back as his machine only works one way. He tests it for a twenty minute jaunt. However, having lost his girlfriend Kara and his job, a distraught Matthew decides to test his machine after calculating the exponential increasing jumps in time. He leaps forward two weeks into the future only to learn he is a person of interest by the police in a homicide that occurred when he stole a car just before he jumped apparently the vehicle owner dropped dead when Matt and his auto vanished into thin air.--------------------- Knowing he needs to escape, he leaps forward in time, but he learns that each leap is that much longer than the previous one. This time he jumps forward two decades where he learns his device has been found and everyone is waiting for him to reappear when he does. Matthew is a hero and joins MIT. Although the world has dramatically changed while he leaped and his knowledge of physics obsolete, no one has been able to copy his time machine. Now pressure is on him by those who want to use his device so he leaps again two centuries into the future where he seeks a respite knowing that if this fails him the next jump gets into the millennium and there is no reverse.----------------- This terrific science fiction time travel tale feels like a throw back thriller starring a disingenuous antihero struggling with fame as his gizmo works but no one including Matt has been able to replicate what he wrought. Every time the pressure mounts on Matt he leaps, but with the time interval expanding, he knows each subsequent jump is into an unknown future. He learns that with the twenty year leap that prevalent acceptable physics theory were devastated in the interim.

    Solid, nice read

    It's not going to rattle you to the core but it might make you think a bit... all in all, it's just a good read. It's enjoyable, the characters are generally likable and realistic and the concepts are well thought out.
