# 602: Overstimulated

 Overstimulated Title text: My favorite thing to do at parties is to talk judgmentally about people who aren't there.

## Explanation

After being cooped up working on papers, Cueball goes to a party, only to find himself tuning out the chatter of his friends in order to work on math problems in his head. He writes down the prime numbers on cards, and then stretches them out such that the area of the card is the same (say, 1), but one of the sides has been elongated to a length equal to the number on the card. This reduces the length on the other dimension to the reciprocal of the number on the card (i.e. 1/n, with n being the number on the card), according to the area formula for rectangles.

Stacking these reciprocals all up will eventually diverge, meaning the sum will be infinite without ever leveling off. This is unimaginatively referred to as the divergence of the sum of the reciprocals of the primes, and was proven by Euler in 1737.

The Cambridge Aspergers Test includes questions on preferences for, and ability to cope with, social situations. It also asks the person taking the test if they have an affinity for numbers and do they see patterns in every day objects. Cueball would score high on the Asperger's scale.

## Transcript

[There is a group of people. Three women and four men. They are standing around a table with a drink on it.]
Man #3: Have you seen John lately?
Woman #3: He and Claire blew off this party to see Jeff.
Man #4: They do that a lot.
Man #1: Yeah; I don't know what his problem is with hanging out lately.
Man #3: He's like Katie - ever noticed how she only goes somewhere if Jeff's there?
Somebody: It's so lame how s he hangs around him even when he's not single:
Somebody: HE LIKES IT.
Somebody: SOMEONE SERIOUSLY NEEDS TO DATE HER.
Somebody: TOTALLY.
Somebody: And honestly I feel like a jerk but I wouldn't mind if she hung around with us a little less. She needs other friends, you know!
[Cueball (Man #2) is cringing away from all the text; none of the words are attributed to specific people.]
[Cueball peels a hole in the panel. The numbers '1', '2', and '3' are visible through the gap.]
Somebody: HAVE YOU NOTICED HOW EVERY DUDE SHE DATES IS A TOTAL DRUGGIE?
Somebody: I'm glad I'm not the only one who thought that was weird.
Somebody: Michelle dates potheads like Elaine but at least they both have real jobs.
Somebody: Michelle does? She designs those book covers, right?
Somebody: And it's not like she smokes a lot.
Somebody: Elaine is one of those girls who
[The previous panel's text appears again, but peeled back even further. Cueball looks up.]
 1 2 3 4 5 6 7 8 9 10 11 12

[Cueball starts taking down the prime numbers.]
 1     4   6   8 9 10    12    14 15
2 3   5   7        11    13

[Cueball grabs and squeezes the 2, so it is half as wide and twice as tall.]
[A formula: $\sum_{i=1}^{\infty}{1/P_i} = h$ (Sum with i from 1 to infinity of 1/Pi = h)]
[i.e. The sum from 1 to infinity of the inverse of each prime.]
[The panel shows a 2 that is 2 units tall and 1/2 wide, a 3 that is 3 units tall and 1/3 wide, and so on. Cueball is moving the 7.]
[Cueball writes h = infinity. The numbers are piled on their side next to a scale.]
Voice: Don't you agree?
Voice: Hey, wake up.
Man #1: You zoned out or something.
Cueball: Sorry; I must be... tired.
Man #1: I don't blame you. All day cooped up working on papers.
Man #3: Must be nice to get out and relax, huh?
Cueball: Yeah.
[Girl #3 reaches for the glass on the table.]

# Discussion

The explanation needs to mention the irony of Man 3's line in the last panel. 108.162.216.45 12:39, 13 November 2013 (UTC)

The Onion actually ran an article on March 19th 2014 titled "Report: Strongest Human Relationships Emerge From Bashing Friend Who Couldn't Make It Out." 108.162.220.23 21:47, 21 April 2014 (UTC)
