Asteroidal Resources

Just as when you’re pulling nickel out of the ground in Sudbury, when you use ocean water you’re mining asteroids. As I noted in my latest essay, the more we learn about the solar system, the more we discover that, as opposed to being what we long thought was “the water planet,” earth is a comparative desert. The water is mostly extraterrestrial.

To expand on Krafft Ehricke’s famous statement, if God had wanted us to become space faring, he’d have given us a moon. With water on it.

Cats

recognize their own names, even if they don’t bother to respond.

[Update a few minutes later]

OK, statements like this never make any sense to me:

Saito says she thinks feline pets learn to recognize their names because of what is in it for them. “I think cats associated their names with some rewards or punishments,” she says—adding that she thinks it is unlikely the cats understand their names are attached to them. “There is no evidence that cats have the ability to recognize themselves, like us,” she explains. “So, the recognition about their name is different from ours.”

My emphasis. Gee, every time I see a cat ignore itself in the mirror, instead of treating the image like another cat, I think that’s evidence of ability to recognize itself.
