613: Threesome
explain xkcd: It's 'cause you're dumb.
| Threesome |
 Title text: I wanted us to try finding an approximate numeric solution, but noooo. |
[edit] Explanation
The N-Body Problem in physics refers to our inability to analytically solve sets of differential equations modelling gravitational attraction between more than two bodies. In the comic, they describe a physicist's difficulty having a threesome due to his inability to find a closed-form solution. The title text suggests they should settle for a numerical solution since a closed form solution is unavailable.
[edit] Transcript

- Cueball: Why's that awkward?
- Megan: They can't solve the three-body problem.
- Cueball: Ah, yes.
