Perhaps some content would help. Brahmagupta's 7th-century astronomical work contains a chapter on arithmetic, one section of which concerns what he calls "excavation" -- he gives rules as to how to find, essentially, the volume of these... excavations. And I want to say, "the section on excavations, which essentially concerns the three-dimensional geometry of... holes in the ground" only without the "holes in the ground" part.

I had to go lie down, my mood needed to be escaped from. So what happens but I have a bad dream about tortie cat. Ahrg. At this point, I think she must have found her people or something.

Also, experience with Alias, and though I don't watch it much, LOST, have made me highly cynical. I watch Surface, Invasion and Threshold (none really blow me away but I want to know what the hell is going on), all the time wondering if they have any idea where they are going with this and suspecting not.

Nerd hole.

Today has been weird. I've spent too much time telling people things and then getting asked for the exact same information.
