Hamiltonian
The problem with perspective is that it's bidirectional
Title text: The problem with perspective is that it's bidirectional

Explanation

A student, presumably in class, decides that the subject of Hamiltonian circuits in graphs is not important in the larger context of life and love. Later, however, he realizes there is a flaw in the proof presented, while in bed with a girl, and suddenly want to focus on the mathematics, in a humorous reversal of his position about what is meaningful.

Transcript

Lecturer: And therefore, based on the existence of a Hamiltonian path, we can prove that the routing algorithm gives the optimal result in all cases.
Man: Oh my God.
Close-up of Man
(Out of frame): What? What is it?
Man: A sudden rush of perspective. What am I doing here? Life is so much bigger than this!
Man Running out of Room
Man: I have to go.
Man enters darkened room, where woman waits by window.
Man and woman embrace...
...and get into bed.
A heart appears over the supine bodies
Woman: Ohh...
[[Hands <<grip>>]]
Man (out of frame): Wait a moment.
Woman (out of frame): What is it?
Silence
Man (out of frame): His proof only holds if there's a Hamiltonian _cycle_ as well as a path!
Woman (out of frame): ...excuse me?
Man (out of frame): Paper, I need some paper.
Man (out of frame): Hey, do you mind if I jot down some notes on your chest?

Discussion

I don't agree with the title's explanation. IMO the title refers to the fact the "sudden rush of perspective" happens to Cueball also when he is making love, but starts to think about the algorithms. ‎37.128.6.132 (talk) (please sign your comments with ~~~~)

When in math class, he walks out, likely offending his peers, because his mind is occupied with thoughts of love. When making love, he offends his partner because his mind is occupied with math. Some perspective! Mountain Hikes (talk) 01:28, 25 September 2015 (UTC)

I always thought that the talk about the algorithm providing an "optimal result in all cases" was the reason Cueball left - he decided to apply the algo to his life somehow in a way that he would always find a positive outcome, such as love. That also made the end panel funnier for me because as he found a flaw in the algorithm, he self-fulfilled it by interrupting his romance, thus ruining the "optimal path in all cases". Could be wrong here... 108.162.237.254 03:54, 2 April 2016 (UTC)

There's an anecdote about the mathematician Carl Friedrich Gauß, who is said to have jumped out of the bed in the middle of his wedding night, to write down some proof he just found... 162.158.203.144 19:39, 29 April 2016 (UTC)
