Atomic Clocks, Street Views, and Flash Disks

A few random things caught my eye today:

GPS has brought atomic precision time to us in the form of small portable GPS devices, as well as network time-servers that sync with the GPS data. The time from the GPS satellites comes to us with such precision, because the satellites carry cesium atomic clocks on board and are synchronized with ground-based clocks and being corrected for relativistic effects.
But for some folks getting the atomic time from GPS is not enough - they call themselves "Time Nuts" and have atomic clocks (such as the 5071A) at home as a hobby. See also this nice article in Wired today. Wow! I've always loved time, clocks, calendar calculations, leap seconds, and physics. I guess that's a hobby that I could get into, too....

From atomic clocks and GPS it is only a small leap to navigation, which brings us to cartography, which brings us to Google Maps - and the second item of interest today: Google has launched Street View in eight new cities in the US, including Boston. Very cool.

Last, but not least, here is something I want in my next laptop: Toshiba announced a 128GB Flash HDD yesterday. My current laptop has a 80GB conventional disk drive, and it looks like the form factor of that Toshiba drive would allow for an actual replacement.
