I live really close to there, and i just heard about it today. I researched a little but i want to know more! Me and some friends want to go over there soon, and we want to know what it looks like, i have not yet found any pictures or footage of the area, but i have heard a range of stories. I do know for a fact that the real Seven Gates of Hell is located in York Pensylvania. So what do you know, or what can you find out?

I was on my drive home the other day and somehow started to think about this. I know you can achieve constant accelleration, but somehow a system with constant jerk seems just out of my perception. I mean...the velocity would be increasing exponentially. And that seems a bit far fetched to me. What could possibly have so much thrust that it's velocity increases exponentially? I thought maybe a just-fired bullet, but that would be for only microseconds before drag, friction, and gravity all factored in.

I need to understand why you get the answer y = +/- root(x^3 + 2x^2 + 2x + 4) My differential textbook does not explain this and I have forgotten my first year calculus, thanks.

when u do things like 9+10+3=3+9+10 you would say that is the commutative property of addition, but what would 4(3+8)=4(3)+4(8) be. i know it would be distributive but would it be the distributive property of addition or multiplication. thanks for any help!
