And that's a pretty stretchy rope.

Ooh! I thought of one! (An equivalent) We are reviewing a medical report told in first person. Are we patient? Or are we doctor?

I hear this song on a commercial about a dozen times a day. (by the Killers) Is there any context in which the title text is...

I left that for the potential discoverer to resolve.

I come up behind them and politely say "Excuse me". They always move. If I am irritated, as I pass I say "Walk left; stand right." And...

A few years ago, I fished a small plank of wood, maybe 8 inches square, out of the lagoon at our yacht club. Rather than just toss it in...

Also: those seem to be six-bar gates.

This was so lame I almost didn't post it.

Here's the animation from the wiki page: The effect is vastly downgraded, as the rope's expansion is on the same order of magnitude as...

Ah. There it is. "What we need to do is think about the ant's position as a fraction of the length of the rope. The above reasoning...

Right. Yeah. You're right. The ant is 1/100,000th of the way along the rope, so only 1/100,000th (~1cm) of the total 1km expansion...

The rope is expanding in both directions. After one second, the ant is already about 25% along its length.

The one guy who said he recalls the problem said it would take 10^some ungodly number years, so that tracks.

Assuming I made no mistakes, here's a complete answer.

As a spreadsheet: I guess I haven't proven that column G reaches one in a finite number iterations....
