### Re: [Biology] Are we pooing correctly?

Well, theres still some distance between ankles and exit as my feet are slightly forward relative to my behind, although I suppose it'd be fairly close.

### Re: [Biology] Are we pooing correctly?

### Re: Boolean Algebra question

I'm pretty sure V ('or') is a binary operator, so the third thing is just an ambiguous form of one of the first two (I'd probably consider it the same as the first), versus being a third similar but different statement.

### Re: Pound v. Foot Pound

Is it reasonable to assume the impact only lasts as long as it takes to decelerate down to 0? The way I imagine such an impact would have it bounce off, so the overall change in momentum (and so the average force) would be somewhat greater.

While 16-x^4 is indeed a difference of squares, what you have at that stage is actually 16-x^4(x-1)^2, which also happens to be a difference of squares, but a different one from what you did.

Do you have a final answer you're trying to get, or how did you know something was wrong?
