 Title text: In Rio de Janeiro in 2016, the same jump will get an athlete 0.25% higher (>1cm) than in London four years prior. |
[edit] Explanation
Here's the xkcd comic that is cited in the first frame. That comic is a discussion between centrifugal force and centripetal force.
And obviously in this comic, the angry pole vaulters are able to pole vault up to Cueball's balcony to "get" him.
[edit] Transcript
- Cueball: Did you know that because of centrifugal* force and the shape of the Earth, "gravity" can vary by nearly half a percent between major cities?
- Yes, centrifugal. xkcd.com/123
- Cueball: That's not a lot, but it could affect, say, pole vaulting. In a 5m jump, it could make a difference of 2cm.
- Megan: Huh, interesting.
- Cueball: I'm going to write an article reevaluating vaulting records to take this into account.
- Three days later:
- Megan: Good job. There's an angry mob of athletes outside.
- [He looks off the balcony. The mob of athletes is out of frame.]
- Athlete: That record was mine!
- Athlete: How dare you cast doubt on our honor?
- Athlete: Have you no respect?!
- Athlete: Make him pay!
- Cueball: Hey, the math doesn't lie. Suck it, jocks.
- Megan: Dude, don't provoke them.
- Cueball: Whatever. The building's locked. Let 'em vent for a--
- crash
- Off-panel Athlete: GET HIM!
- Cueball: Crap!
- Cueball: How did the pole vaulters get up to our balcony?
- Megan: ...
- [Beat frame]
- Megan: That might be the stupidest question I've ever heard.
- Cueball: Right.
