I saw a facebook update by Peter Thoeny, where he posted a link to an article about how executives can lead more effectively by being community managers. I read it and liked it, so I thought I’d share it as well.
I was looking for articles about really accurate clocks (OK, I’m using ‘accurate’ colloquially[nbnote ]http://en.wikipedia.org/wiki/Accuracy_and_precision[/nbnote]) and came across this one from late 2007, about “How Super-Precise Atomic Clocks Will Change the World in a Decade” and I was just intrigued by some of the things I saw in there.
