When a robot is falling, meaning its center of gravity is not centered over the foot (or feet) on the ground, the error grows by e^(t/.5)

I need to know more. There are a few "universal constants" (the world is as so until I say no) I'm trying to get across to my krav students, and being balanced is a biggie. It's surprising (and yet not) how many times I have to point out that if your head isn't at least within the floor area marked by your stance, you're not properly stable. Mathy stuff? Will make me seem even more right, even if none of us understand it.

Potbelly's is rather nummy. Between them and Quiznos, I never go to Subway anymore.

Next time someone is standing in an unstable fashion, say, "Dude, you don't want your error to grow by e^(t/.5), do you?"

Yeah, I dig their sandwiches, and also the potato soup and the shakes.

Oh, I miss Potbelly's. The shakes are Teh Yum.

I also like how they generally won't serve you if you're talking on your cell phone.

HA. This is right near where I work: [link]

Good thing I didn't take the bus that goes by there this morning.

Dynamically balancing—the way we walk—is much harder. It looks fairly smooth when we do it, but it's really a controlled fall.

This explains how superheroes like Batman and Daredevil get around town. It's a controlled fall taken to the next level.

There's no rule that says you have to control the fall with your feet.

So no news yet on SPN being renewed?
