Yawning - I have at least one friend in the set that will never get caught in a group yawn. And they see that as GOOD thing. Sigh.

For my part, just reading about it brought one on. *rolls eyes*
Am I a sheep, or what?

I was yawning, too...

And, if I understand the theory behind the lasers correctly, they actually don't use that much energy -- the thing with pulsed lasers is that they compress a small amount of energy into a very short amount of time, thus getting a large power (energy/time).

So when they say it has more energy in it than all the power plants, they mean for that nanosecond (and perhaps in the near future, picosecond). It's a cute, stupid media contrivance, which sounds impressive but merely confuses.

So sayeth PHYSICS EDUCATION MAN!

My work here is done.
