[ Double Curvature ]

Double Curvature.. what is it? I have no idea. I just made up the term right now. *Me goes look in a dictionary for a meaning*

Okay here we go.. copy paste...

1. The act of curving or the state of being curved.
2. Mathematics.
   1. The ratio of the change in the angle of a tangent that moves over a given arc to the length of the arc.
   2. The limit of this ratio as the length of the arc approaches zero.
   3. The reciprocal of the radius of a circle.
3. Medicine. A curving or bending, especially an abnormal one: curvature of the spine.

Okay.. now when there's a double... the limit of the ratio as the length of the arc approaches zero... Limits are like ... something else, I can't be bothered thinking anymore.

Okay, new meaning. Hitting rock bottom for the second time.

Think of an action hero who just dodged a bullet, and falls out of a building. He hits the bottom for the first time. He runs back up the stairs (as all heroes do) and then he gets kicked off again by the villain. That's double curvature. Ouch.

Lol.... ?
