What time is it?

In a story about how the rotation of the earth has slowed 2/1000 of a second over the last century, science writer Ivan Amato explains how dependent our technology is on extremely accurate time-keeping.  For example, if the clocks in your GPS device and the satellite it connects to are out of synch by as little as 1/1000 of a second, your location would be thrown  off by hundreds of miles.

Remember Stewart Lundy, my former student who helped me with the technical side of my blog?  He has now embraced farming.  But what a farm!  He is doing cutting-edge local, sustainable, organic farming.  He is raising heirloom vegetables, chickens, ducks, rabbits, bees, and “rare pigs.”  People are driving an hour and a half just to buy his eggs.  He is attending to the microbes in the soil, restoring minerals to the soil, and applying all kinds of other sophisticated techniques to make all of this work.

Contact him from the site if you want to order a pig (either as food or as a pet) or get in on any of this other stuff.  [Read more…]
