Wired's Quinn Norton has a great feature in today about amateur clock-hackers who build their own super-accurate atomic clocks. These "Time Nuts" pull stunts like taking their kids hiking in the mountains for a couple days, using their cesium clocks to recreate Einstein's time-gravity experiment to prove that the family had gained 22 nanoseconds on their neighbors by rising high above Earth's gravatic center.
This is just part one -- more tomorrow!
With the end of the Cold War, and with telecommunications technology advancing rapidly, surplus stores and eBay have filled up with discarded precision time equipment once beyond the reach of all but governments. Cesium clocks, rubidium clocks and even the occasional hydrogen maser can be had for less than a decent laptop.

Some of this equipment costs upwards of $50,000 new.
Their access to once-forbidden technology lets the time hackers play in a realm of precision that underpins the modern technological world. A select few, like Van Baak, have started exploring the underpinnings of the universe.

The bad news: that’s the only connection, and it’s otherwise a modern dumbphone with no clear picture yet on how well-designed the interface and hardware is. It’s […]

Although there will never be a consensus about the best way to make coffee, any coffee connoisseur will agree that controlling the grind of your beans and balancing water temperature are the keys to a tasty cup. Since your plastic coffee pot doesn’t really allow for that kind of customization, going back to the French […]
