Yeah, that's great. Are you really agreeing with the theory that dino's ran uphill SO MUCH that evolution picked the ones that would do it BETTER than the other ones?
I said nothing about whether or not I agree with the theory. I was merely correcting his misconception that the downward force doesn't help the bird in moving up the slope. Whether or not this actually helped evolutionarily is another question.
has to be the most rediculous theory I have EVER heard. Extra downforce for running uphill??
The extra downforce increases the normal force exerted from the ground on the bird. Friction is proportional to the normal force, and thus provides more traction to allow the bird to run up the slope (rather than allowing the bird to slide back down the slope).
Think about it... imagine you have a slope with a block that kept sliding down it. If you push down on the block, you can prevent the block from sliding down.
Learn some physics before you make comments like that.:-P
Oooh, can the glass go transparent? I'd love a window that doubles as a computer. I bet it can't:(
Actually, I'm pretty sure it can be made to. Even many conventional LCD displays can be made to do this since LCD's are basically mechanisms to block or let light through. Certain projectors work this way (with a light that shines through an LCD panel).
I remember some company making a laptop a few years ago (I don't remember the brand nor the model unfortunately) that doubled as a slide projector if you take the backplate off and put it on top of a conventional overhead projector.
So in principle, it's not impossible today to make your LCD window.
If my organization owns the A.B.C network, there is no reason why any packets bearing a source address of anything other than A.B.C.* should be permitted to leave my network.
Easier said than done... that may be true for smaller networks, but isn't the case for larger ISPs. The IP address structure is no longer strictly heirarchical anymore (e.g. CIDR and multihomed networks) and peering relationships between different AS's make this extremely difficult to implement.

Well, there's that DMCA we all can't seem to get rid of...
