Oy. So I find myself sitting in my disgustingly messy office. And I’ve got a problem. The Math Carnival is coming to town. All those geeks, and the chaos that they always cause. Oy.
But I’m stuck. After all, I have student loans that need to be payed off early, and the kind of work I do doesn’t exactly bring in as much cash as running an oil company. Besides, maybe I can talk someone who’s been confused by all the math geekery into accepting my compounding payment plan – then I’d be set!
Next thing I know, an ant comes strolling into my office. I knew I should have gotten rid of those dirty dishes. But when I tried to chase him out, he up and tells me that he’s not here for the food; his hive is trying to solve the traveling salesman problem, and he’s just traversing a graph. Great, just what I needed. Geeky ants. I tried to trick him and his pals into climbing onto a handy convenient hyperbolic Escher print, but they wouldn’t fall for it. So I had to pull out the heavy guns: the best way to get rid of geeky ants is to find a hungry geeky spider.
Ants taken care of, I sat down to ponder my next move. And in walks what looks like an actual client! Just what I needed. “So, what can I do for you?” I asked, putting on my best inquisitive helpful face. “I’m confused about this number stuff. There’s
Rational numbers, irrational numbers, and imaginary numbers. And then there’s triangular numbers, and then there’s tetrahedral numbers. I just don’t get them. Can’t you please help me find a nice, simple, uninteresting number? Something with nothing special about it?”. That’s when I lost my temper: “Take you stinking Gödel jokes and get out of my office!”.
After that, I decided I deserved a break, so I headed down to the pub for a
nice pint of Guinness. But with the math geeks in town, you can’t even escape in a pub.
Sitting on the bar in front of me is a magic star puzzle. Just
what I needed – another math puzzle. I couldn’t face that; I needed something easier.
And I saw it at one of the tables. The good old 15 puzzle. Any 10 year old can do that!
So I wandered on over. But no, those math geeks couldn’t leave a good simple
puzzle alone – they
needed to go and play with it, and make it all complicated.
Now I started to get really frustrated. Geeky ants invading my office, messed up puzzles at my pub – what could I do? I had to do something about this. And then it struck me: math geeks love Rubiks cube, and I just happened to know how to solve it. I thought maybe if I dazzled ’em, they’d leave me alone! So I found a table with a rubiks cube on it, and got to work.
I should have known better. They decided that I must be one of them, and starting chattering on about how the rubiks cube is really all about group theory. And once that got started, things went downhill fast. From group theory, they wandered into permutations and fixed points, and from there, it was just a short trip before there were a dozen conversations going on at once about numbers and number theory – one guy had an equation for generating prime numbers; another starting talking about how to do prime factorings of numbers… And then one pops up with stuff about Fibonacci sequences. Hey, finally something I understand! I remember those things. But just my luck, he was talking something about how Fibonacci-like series were sort-of the same thing as differential equations. Oh, great… Just what I neededed: nightmare flashbacks from college.
Next thing I knew, I was waking up on the floor. I’d fainted. Damn it, I’m not supposed to faint! And some guy is trying to wake me up, not with a good stiff drink, not with smelling salts, but with a be-damned fractal: he’s flashing different resolution images of the Koch curve in my face!
As I pushed the fractals out of my face, I saw that there were more people around me trying to help: fanning me, offering me a drink, and of course, talking. And not just chit-chatting – talking math. Even on the floor I couldn’t get away from it! One guy is explaining why I passed out – something about the conflict between analytical and intuitive thinking; while another gal is explaining how she’s seen this before: it’s all just math trauma.
At that point, I dragged my sorry behind off the floor, and headed out of the pub. No way I could stand any more of that! But where could I go? Where could I escape where no math geeks could find me? And then it hit me: the Natural History Museum’s anthropology exhibit! No math geek would be there! So I hopped a bus to head across town. We got to the museum, but the bus kept going? “Hey driver, you just missed my stop” I shouted. He replied, with an evil geekish grin: “Yeah, well, this bus has a halting problem buddy!”. God(el) help me, they’d even taken over the transit system!
I pried open the door and dived out onto the pavement. Fortunately, the bus wasn’t moving too fast, so I got away with nothing more that a ripped coat and a skinned elbow. Of course, some guy who saw that started up about how my elbow reminded him of some
interesting topological spaces – and would I like to see his introduction to algebraic topology. I ran towards the museum entrance, tripping over a guy hunched over a one of the best best telescopes under $500 I had seen, I know this because I started talking to him about how math is used for astronomy. Finally, I made it inside, and ran for the anthropology section. I had to be safe there!
Safe at last, I took a seat on a bench in front of an interesting exhibit on
the roman armies, and how they set up their camps in new territory. Interesting. Until someone comes up behind me, and starts explaining how to measure the statistical significance of the orientation of the camps!. Even in an exhibit on ancient Rome I can’t get away from them!
I had to get away. But where could I go? Even the museum wasn’t safe. I’d reached my limits. I headed home, locked my door, boarded up my windows, and hid under my bed until the Math Carvival was over.
