Theoretically useless knowledge No. 2

No.

If you walk South a mile, then East a Mile, and shoot a bear. Then walk a mile North back to camp...then what color is the bear?

Yes, you can. All of you except the pin point vertical projection through you directly at 90 degrees latitude, that is. Just spin to your left like a top.

White

I think the hair is actually clear but the light diffraction makes us think it is white.

From polarbearsinternational:

Fur. Polar bears' fur consists of a dense, insulating underfur topped by guard hairs of various lengths. It is not actually white‰ÛÓit just looks that way.

Each hair shaft is pigment-free and transparent with a hollow core that scatters and reflects visible light, much like what happens with ice and snow.

Polar bears look whitest when they are clean and in high angle sunlight, especially just after the molt period, which usually begins in spring and is complete by late summer. Before molting, accumulated oils in their fur from the seals they eat can make them look yellow.

I've never seen a polar bear except in a zoo. I have seen Grizz in their environment. And everything you think about humans being at 'the top of the food chain' pretty much goes out the window when you see what those critters can do, with malice of forethought.

Soooo..if I'm ever at "ninety degrees north" and see what appears to be a white bear; I doubt if I pause to ponder if his coat is really white or not....;)

East would be counter-clockwise, I believe. Unless, of course you were 90å¡ south latitude, then it would be clockwise. :rofl:

Not sure that would work at 90 south.....
