Sci-fi makes it look so easy. Receive a distress call from Alpha Centauri? No problem: punch the warp drive and you're there in minutes. Facing a catastrophe that can't be averted? Just pop back in the timestream and stop it before it starts. But for those of us not lucky enough to live in a science-fictional universe, are these ideas merely flights of fancy--or could it really be possible to travel through time or take shortcuts between stars? Cutting-edge physics may not be able to answer those questions yet, but it does offer up some tantalizing possibilities. In Time Travel and Warp Drives, Allen Everett and Thomas A. Roman take readers on a clear, concise tour of our current understanding of the nature of time and space--and whether or not we might be able to bend them to our will. Using no math beyond high school algebra, the authors lay out an approachable explanation of Einstein's special relativity, then move through the fundamental differences between traveling forward and backward in time and the surprising theoretical connection between going back in time and traveling faster than the speed of light. They survey a variety of possible time machines and warp drives, including wormholes and warp bubbles, and, in a dizzyingly creative chapter, imagine the paradoxes that could plague a world where time travel was possible--killing your own grandfather is only one of them Written with a light touch and an irrepressible love of the fun of sci-fi scenarios--but firmly rooted in the most up-to-date science, Time Travel and Warp Drives will be a delightful discovery for any science buff or armchair chrononaut.Binding Type: Paperback

Just fine if you have simple needs...
Color: Black/Digital/Black/Green
Exactly what I needed: a cheap, durable wrist watch. The only thing it was lacking were instructions, but about 5 minutes of messing with the buttons got it set up

I purchased this watch on whim, I was pleasantly surprised at how good it looks. I just love the design of the face. THe quality is good. I did change the strap for a premium leather. It comfortable to wear. Worth the money in my opinion.

Really nice and unique watch
Color: Black/Black/Black
This watch really caught my eye on Amazon. Every once in awhile you order an item and it looks better in person than it does in a picture. This is one of those items. It looks really great in person! I collect mostly unique watches that look different than a normal watch. What is really unique about this watch is that it has 2 separate second hands. One that is always ticking for the time and another one that starts going with the Chronograph. Not sure I've ever seen that on another watch. Sure I've seen subdials that do this, but this is 2 full size second hands. And they look different also so they don't get confused. I've never seen this one in a store which is a shame because I think Timex has some great watches right now and I don't think a lot of people know about them.

nice but.
So, this really is a nice watch and if you can get it on sale it's a bargain. The bracelet is junk, with hollow end links. I would recommend replacing that with some type of fabric or rubber type strap. The reason I took one star off is because the chrono function isn't the best style. If you don't plan to use it much or only plan to use it for 10 minutes or less that's fine. More than that and the minutes counter flies back to zero and starts counting again which can be confusing and the next register is the combo 24hr and chrono minutes/hours counter which isn't easy to use for timing say 30 minutes or so. The standard type chrono counters are way better by design and Timex sells another one with standard counters with neat multicolored registers for less money.
Otherwise it's a solid watch comfortable to wear not too big or thick or heavy. Of course it has mineral glass for the xtl so you need to be careful or it will scratch pretty easily but for the price.....
