Coming soon Atomic clock accuracy on a chip.

[hmelton]

I don't think it actually uses the oscillation of cesium 133 so there isn't actually 9,192,631,770 cycles for each second, but the makers of this clock claim it has accuracy comparable to an cesium 133 atomic clock and is a chip level device.

This is good. perhaps we will get gps devices that don't nom batteries like no tomorrow now. And getting more life out of our [cellphones/handhelds/external brains] is always a bonus.

Might be better to http://www.physorg.com/news77890657.html]just get rid of batteries entirely.

Any idea how that's been going?  That article is from 2006, and they were hoping to have some sort of results within a year, so it should be nearly done by now.

Good question. I got the link from an aggregator yesterday morning, and I didn't notice the date until I closed the window after posting that reply.

A quick Googling indicates that they're apparently still working on it, as I've found diagrams and papers about design tweaks and improvements dating from as recently as 2009.

Weren't Toshiba at one point working on a fuel cell or micro-turbine powerpack for their laptops?

Atomic clocks?

dose that mean i have to worry about being robed by a time lord?

[Bob Schroeck]

Well, it depends on whether or not Time Lord robes are to your taste. I, personally, would hate to have to wear that huge ceremonial collar/crest thing.

Actually having chip level atomic clocks means you could in theory use an array of laptops or even cell phones to sense when and where a time lord thief tries to sneak in and park his TARTIS.

The minor time/space distortions created by any time machines materializing or passing through would be fairly easy to sense by comparing the changes in the time measured by the atomic clock chips on computers, cellphones and cellphone towers.

once a TARTIS materializes it's singularity would be relatively easy to locate with a few dozen cell phones equipped with atomic clock chips and a wireless network that allows them to talk to each other and compare the changes in the atomic clock chips.

Now that would be a Java cell phone application someone needs to write. Use the phones WI Fi or Bluetooth capability and atomic clock to form a sensor network that maps out the local distortions to space/time and home in on the sources.
