First Atomic Clock Wristwatch
- metageek 16y agoI liked this part: >Batteries are included (they last about 45 minutes but are rechargeable).
- die_sekte 16y agoSolution: Attach a better power source, e.g. a small nuclear reactor, to the other wrist.
- oiuyftgrghjk 16y agoBut if you carry the clock with you then it only tells you the time in your own frame of reference - which is totally useless. I can have a broken watch that tells me the time only for me. If you want to meet someone for coffeedo you want to have to tell them your speed, direction and altitude so they can make the necessary SR and GR corrections to their frame of reference?
- cnvogel 16y agoSorry to correct you, but that single atomic wristwatch is totally inadequate to reliably detect the effects predicted by general relativity. You'd better use at least three (and compare their readings with the home-based hydrogen maser) for that experiment, which TVB dutifully carried out - on a weekend-trip with his kids. http://leapsecond.com/great2005/ http://leapsecond.com/great2005/
- oiuyftgrghjk 16y agoBut if you believe GR and have a geological map for your position you can work out the correction reasonably accurately
- wazoox 16y agoSoon available from the best jewellers ? This is hilarious. At least I hope it's precise enough to measure the effect of gravity on your own time frame :)
- kno 16y agoAt least he gets to exercise carrying this box around.
- hardy263 16y agoReminds me of how old cell phones used to look like. Now if only we could apply moore's law to quantum mechanics, eventually it'll reach the size of a normal wristwatch!
