More Jeopardy Math

September 5, 2008

I was recently reminded of my all-time favorite Final Jeopardy clue (I can’t remember the exact wording), which showed up many (>15) years ago:

This is the only positive number such that adding it to itself and multiplying it by itself give the same result.

The question, “What is 2?”, is a no-brainer for anyone who’s played with numbers, and I’ve played with numbers a lot, so I knew the question. What struck me, though, was that nobody got it right. Two people guessed 1, and one guessed 1.5. 1.5?! This is why we tell our students to check their work.

OK, so three Jeopardy contestants can’t do arithmetic in 30 seconds under bright lights with millions of people watching them. I can forgive that. (Maybe they’d have had better luck with this one.) But it got me wondering about how often math appears as a Jeopardy category. Luckily, there’s the J! Archive, which has just about every clue from every show ever aired. And it’s searchable! So here’s the list of all Jeopardy clues containing the string “math”. (Note that this includes the occasional clue with a word such as “aftermath” or “Mathew”. Also, my favorite clue isn’t in the archive – I said almost every clue.) Here are a few good ones:

  • (Mathematics, $1000): He never revealed the proof of his last theorem, but only hinted at it in a margin note. (answer)
  • (Math Terms, $600): It describes the shortest line between 2 points on a surface, or a dome made with the least possible material. (answer) (This is pretty sophisticated, don’t you think?)
  • (Milestones in Math, $600): This Persian poet’s work on algebra included systematic solutions to cubic equations. (answer, and his Rubaiyat)

Of course, once I’d found a searchable archive of Jeopardy clues, I immediately looked for my favorite category (no, it’s not Math): Stupid Answers. A few examples:

  • Oddly, this piece of furniture was never built for the throne room at Neuschwanstein Castle (the throne)
  • In the musical “The Phantom of the Opera”, the Phantom writes one of these, called “Don Juan Triumphant”. (an opera)
  • He formed United Artists with Griffith, Pickford & Fairbanks & in 1915 lost a Charlie Chaplin look-alike contest. (Charlie Chaplin)

I love Jeopardy. If nothing else, it serves as a reminder of just how much I don’t know. But I enjoy when they decide to include math clues, because at least I have a chance.

Jeopardy Does Analytic Geometry

December 22, 2007

On Thursday, December 20, the Final Jeopardy clue, in the category “Snack Brands”, was (emphasis mine)

Each unit in this brand, introduced in 1968, is a hyperbolic paraboloid, & they fit together for perfect storage.

Anyone who’s had my Calculus III course should know the answer, because it’s one of the examples. Here’s what they look like (courtesy of Wikimedia Commons):

hyperbolic paraboloid

Oddly enough, this isn’t the first mention of hyperbolic paraboloids on network TV. They also showed up on The Simpsons, in Treehouse of Horror IX, as Homer and Kang argue on the Jerry Springer Show:

Homer: You lousy two-timing [bleep-bleep]! I’m gonna [bleep]!

Kang: Oh yeah? Well [bleep] hyperbolic paraboloid! [bleep] yo mama!

I guess it’s an insult as well as a quadric surface.
