My Fox News column is up, and as I promised, it's the solar sail story. But I just noticed that I wrote:

Imagine that the sail is at an angle with respect to the sun. Some of the thrust is directed radially along its orbit...

Rather than "radially" it should have been "tangentially."

That post has been up there with that error for days. I thought you guys are supposed to be fact checking my ass! Falling down on the job again, eh?

The Fox News folks have fixed it. Down the memory hole...

Any way you can get me one of them jet packs (like the ones worn in the "Lost in Space" pilot)? I've wanted one of those things since I was a little kid.

Something tells me you already have one.

Here you go.

I can't afford one, though...
