So I find myself sitting in my disgustingly messy office. And I&#8217;ve got a problem. The Math Carnival is coming to town. All those geeks, and the chaos that they always cause. Oy.<\/p>\n<p><!--more--><\/p>\n<p>But I&#8217;m stuck. After all, I <a href=\"http:\/\/getting-green.blogspot.com\/2007\/02\/why-you-should-pay-off-your-student.html\">have student loans that need to be payed off early<\/a>, and the kind of work I do doesn&#8217;t exactly bring in as much cash as <a href=\"http:\/\/jonswift.blogspot.com\/2006\/04\/due-compensation-at-exxon.html\">running an oil company<\/a>. Besides, maybe I can talk someone who&#8217;s been confused by all the math geekery into accepting my <a href=\"http:\/\/math-play.blogspot.com\/2006\/09\/boy-and-storekeeper.html\">compounding payment plan<\/a> &#8211; then I&#8217;d be set!<\/p>\n<p>Next thing I know, an ant comes strolling into my office. I <em>knew<\/em> I should have gotten rid of those dirty dishes. But when I tried to chase him out, he up and tells me that he&#8217;s not here for the food; his hive is trying to solve the traveling salesman problem, and he&#8217;s just <a href=\"http:\/\/growthratenlgn.wordpress.com\/2007\/02\/22\/the-ants-traverse-connected-graphs-hoorah-hoorah\/\">traversing a graph<\/a>. Great, just what I needed. Geeky ants. I tried to trick him and his pals into climbing onto a handy <a href=\"http:\/\/discreetmath.blogspot.com\/2007\/02\/hyperbolic-frolic.html\">convenient hyperbolic Escher print<\/a>, but they wouldn&#8217;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 href=\"http:\/\/jd2718.wordpress.com\/2007\/02\/21\/puzzle-is-the-spider-hungry\/\">a hungry geeky spider.<\/a><\/p>\n<p>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. &#8220;So, what can I do for you?&#8221; I asked, putting on my best inquisitive helpful face. &#8220;I&#8217;m confused about this number stuff. There&#8217;s<br \/>\n<a href=\"http:\/\/scienceandreason.blogspot.com\/2007\/02\/numbers-rational-and-irrational-real.html\">Rational numbers, irrational numbers, and imaginary numbers<\/a>. And then there&#8217;s triangular numbers, and then there&#8217;s <a href=\"http:\/\/www.mathlesstraveled.com\/?p=56\">tetrahedral numbers<\/a>. I just don&#8217;t get them. Can&#8217;t you please help me find a nice, simple, uninteresting number? <a href=\"http:\/\/11011110.livejournal.com\/91281.html\">Something with nothing special about it?&#8221;<\/a>. That&#8217;s when I lost my temper: &#8220;Take you stinking G\u00f6del jokes and get out of my office!&#8221;.<\/p>\n<p>After that, I decided I deserved a break, so I headed down to the pub for a<br \/>\nnice pint of Guinness. But with the math geeks in town, you can&#8217;t even escape in a pub.<br \/>\nSitting on the bar in front of me is a <a href=\"http:\/\/heath.hrsoftworks.net\/archives\/000073.html\">magic star puzzle<\/a>. Just<br \/>\nwhat I needed &#8211; another math puzzle. I couldn&#8217;t face that; I needed something easier.<br \/>\nAnd I saw it at one of the tables. The good old 15 puzzle. Any 10 year old can do that!<br \/>\nSo I wandered on over. But <em>no<\/em>, those math geeks couldn&#8217;t leave a good simple<br \/>\npuzzle alone &#8211; <a href=\"http:\/\/headinside.blogspot.com\/2005\/06\/40-30s-4-15.html\">they<br \/>\nneeded to go and play with it, and make it all complicated.<\/a><\/p>\n<p>Now I started to get really frustrated. Geeky ants invading my office, messed up puzzles at my pub &#8211; 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 &#8217;em, they&#8217;d leave me alone! So I found a table with a rubiks cube on it, and got to work.<\/p>\n<p>I should have known better. They decided that I must be one of them, and starting chattering on about <a href=\"http:\/\/unapologetic.wordpress.com\/2007\/02\/22\/rubiks-magic-cube\/\">how the rubiks cube is really all about group theory<\/a>. And once <em>that<\/em> got started, things went downhill fast. From group theory, they wandered into <a href=\"http:\/\/blog.plover.com\/math\/fixpoints.html\">permutations and fixed points<\/a>, and from there, it was just a short trip before there were a dozen conversations going on at once about numbers and number theory &#8211; <a href=\"http:\/\/foxmath.blogspot.com\/2007\/02\/6-4-2-4-2-4-6-2.html\">one guy had an equation for generating prime numbers<\/a>; another starting talking about how to <a href=\"http:\/\/mathmeth.com\/arm\/arms\/arm7.pdf\">do prime factorings of numbers<\/a>&#8230; 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 <a href=\"http:\/\/abstractnonsense.wordpress.com\/2007\/02\/15\/fibonacci-type-sequences-part-2\/\">how Fibonacci-like series were sort-of the same thing as differential equations.<\/a> Oh, great&#8230; Just what I neededed: nightmare flashbacks from college.<\/p>\n<p>Next thing I knew, I was waking up on the floor. I&#8217;d fainted. Damn it, I&#8217;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 <em>fractal<\/em>: he&#8217;s flashing different resolution images of <a href=\"http:\/\/www.arunn.net\/scienceblog\/2006\/08\/28\/the-koch-curve-and-visual-resolution\/\">the Koch curve<\/a> in my face!<\/p>\n<p>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, <em>talking<\/em>. And not just chit-chatting &#8211; talking math. Even on the floor I couldn&#8217;t get away from it! One guy is explaining why I passed out &#8211; something about the conflict between <a href=\"http:\/\/www.textsavvyblog.net\/2007\/01\/dual-process-theory.html\">analytical and intuitive thinking<\/a>; while another gal is explaining how she&#8217;s seen this before: it&#8217;s all just <a href=\"http:\/\/letsplaymath.wordpress.com\/2007\/02\/20\/a-mathematical-trauma\/http:\/\/www.textsavvyblog.net\/2007\/01\/dual-process-theory.html\">math trauma<\/a>.<\/p>\n<p>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&#8217;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? &#8220;Hey driver, you just missed my stop&#8221; I shouted. He replied, with an evil geekish grin: &#8220;Yeah, well, this bus has a <a href=\"http:\/\/viked.livejournal.com\/19874.html\">halting problem<\/a> buddy!&#8221;. God(el) help me, they&#8217;d even taken over the transit system!<\/p>\n<p>I pried open the door and dived out onto the pavement. Fortunately, the bus wasn&#8217;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<br \/>\ninteresting topological spaces &#8211; and would I like to see his <a href=\"http:\/\/blog.mikael.johanssons.org\/archive\/2006\/01\/introduction-to-algebraic-topology-and-related-topics-i\/\">introduction to algebraic topology<\/a>. I ran towards the museum entrance, tripping over a guy hunched over a one of the best <a href=\"https:\/\/familyfuntures.com\/best-telescopes-under\/\">best telescopes under $500<\/span><\/a> I had seen, I know this because I started talking to him about how <a href=\"http:\/\/www.lolife.com\/astronomy\/starhouse\/Starhouse%20Blog\/A0149B7D-5C0D-4E5F-B936-389B2D335138.html\">math is used for astronomy<\/a>. Finally, I made it inside, and ran for the anthropology section. I had to be safe there!<\/p>\n<p>Safe at last, I took a seat on a bench in front of an interesting exhibit on<br \/>\nthe roman armies, and how they set up their camps in new territory. Interesting. Until someone comes up behind me, and starts explaining how to <a href=\"http:\/\/iscience.wordpress.com\/2007\/02\/17\/roman-camps\/\">measure the statistical significance of the orientation of the camps!<\/a>. Even in an exhibit on ancient Rome I can&#8217;t get away from them!<\/p>\n<p>I had to get away. But where could I go? Even the museum wasn&#8217;t safe. I&#8217;d reached my <a href=\"http:\/\/scientopia.org\/blogs\/goodmath\/2007\/02\/basics-limits\">limits.<\/a> I headed home, locked my door, boarded up my windows, and hid under my bed until the Math Carvival was over.<\/p>\n<hr \/>\n<p>Without the silliness, here&#8217;s the list of articles in this issue of the carnival.<\/p>\n<p>\u00a0<\/p>\n<table border=\"2\">\n<tbody>\n<tr>\n<th>Author<\/th>\n<th>Blog<\/th>\n<th>Article<\/th>\n<\/tr>\n<tr>\n<td>John Armstrong<\/td>\n<td>The Unapologetic Mathematician<\/td>\n<td><a href=\"http:\/\/unapologetic.wordpress.com\/2007\/02\/22\/rubiks-magic-cube\/\">Rubik&#8217;s Magic Cube<\/a><\/td>\n<\/tr>\n<tr>\n<td>Mark Chu-Carroll<\/td>\n<td>Good Math\/Bath Math<\/td>\n<td><a href=\"http:\/\/scientopia.org\/blogs\/goodmath\/2007\/02\/basics-limits\">Basics: Limits<\/a><\/td>\n<\/tr>\n<tr>\n<td>Charles Daney<\/td>\n<td>Science and Reason<\/td>\n<td><a href=\"http:\/\/scienceandreason.blogspot.com\/2007\/02\/numbers-rational-and-irrational-real.html\">Numbers &#8211; Rational and Irrational, Real and Imaginary<\/a><\/td>\n<\/tr>\n<tr>\n<td>Tyler DiPietrantonio<\/td>\n<td>Growth Rate O(n lg n)<\/td>\n<td><a href=\"http:\/\/growthratenlgn.wordpress.com\/2007\/02\/22\/the-ants-traverse-connected-graphs-hoorah-hoorah\/\">The Ants Traverse Connected Graphs, Hoorah, Hoorah<\/a><\/td>\n<\/tr>\n<tr>\n<td>Mark Dominus<\/td>\n<td>The Universe of Discourse<\/td>\n<td><a href=\"http:\/\/blog.plover.com\/math\/fixpoints.html\">Cycle Classes of Permutations<\/a><\/td>\n<\/tr>\n<tr>\n<td>David Eppstein<\/td>\n<td>1101110<\/td>\n<td><a href=\"http:\/\/11011110.livejournal.com\/91281.html\">Wikipedia and the Interesting Number Paradox<\/a><\/td>\n<\/tr>\n<tr>\n<td>Foxy<\/td>\n<td>Foxmaths<\/td>\n<td><a href=\"http:\/\/foxmath.blogspot.com\/2007\/02\/6-4-2-4-2-4-6-2.html\">6,4,2,4,2,4,6,2<\/a><\/td>\n<\/tr>\n<tr>\n<td>jd2718<\/td>\n<td>JD2718<\/td>\n<td><a href=\"http:\/\/jd2718.wordpress.com\/2007\/02\/21\/puzzle-is-the-spider-hungry\/\">Is the Spider Hungry?<\/a><\/td>\n<\/tr>\n<tr>\n<td>Mikael Johansson<\/td>\n<td>Michi&#8217;s Blog<\/td>\n<td><a href=\"http:\/\/blog.mikael.johanssons.org\/archive\/2006\/01\/introduction-to-algebraic-topology-and-related-topics-i\/\">Introduction to Algebraic Topology and related topics<\/a><\/td>\n<\/tr>\n<tr>\n<td>Vikas Kedia<\/td>\n<td>Livejournal<\/td>\n<td><a href=\"http:\/\/viked.livejournal.com\/19874.html\">The Halting problem<\/a><\/td>\n<\/tr>\n<tr>\n<td>Eric Kidd<\/td>\n<td>Random Hacks<\/td>\n<td><a href=\"http:\/\/www.randomhacks.net\/articles\/2007\/02\/22\/bayes-rule-and-drug-tests\">Bayes&#8217; rule in Haskell, or why drug tests don&#8217;t work<\/a><\/td>\n<\/tr>\n<tr>\n<td>Michael Koppelman<\/td>\n<td>Starhouse Blog<\/td>\n<td><a href=\"http:\/\/www.lolife.com\/astronomy\/starhouse\/Starhouse%20Blog\/A0149B7D-5C0D-4E5F-B936-389B2D335138.html\">Using math for astronomy<\/a><\/td>\n<\/tr>\n<tr>\n<td>Stephen Lavelle<\/td>\n<td>Icecube&#8217;s Keep<\/td>\n<td><a href=\"http:\/\/www.maths.tcd.ie\/~icecube\/2007\/02\/my-favourite-calculation-combination-tones\/\">My favorite calculation: Combination tones<\/a><\/td>\n<\/tr>\n<tr>\n<td>Alon Levy<\/td>\n<td>Abstract Nonsense<\/td>\n<td><a href=\"http:\/\/abstractnonsense.wordpress.com\/2007\/02\/15\/fibonacci-type-sequences-part-2\/\">Fibonacci-Type Sequences, Part 2<\/a><\/td>\n<\/tr>\n<tr>\n<td>Maria Miller<\/td>\n<td>Homeschool Math Blog<\/td>\n<td><a href=\"http:\/\/homeschoolmath.blogspot.com\/2007\/02\/how-four-operations-become-two.html\">How the four operations became two<\/a><\/td>\n<\/tr>\n<tr>\n<td>Arunn Narasimhan<\/td>\n<td>Arrun.net<\/td>\n<td><a href=\"http:\/\/www.arunn.net\/scienceblog\/2006\/08\/28\/the-koch-curve-and-visual-resolution\/\">The Koch Curve and Visual Resolution<\/a><\/td>\n<\/tr>\n<tr>\n<td>Matthew Paulson<\/td>\n<td>Getting Green<\/td>\n<td><a href=\"http:\/\/getting-green.blogspot.com\/2007\/02\/why-you-should-pay-off-your-student.html\">Why you should pay off your student loans<\/a><\/td>\n<\/tr>\n<tr>\n<td>Mr. Person<\/td>\n<td>Text Savvy<\/td>\n<td><a href=\"http:\/\/www.textsavvyblog.net\/2007\/01\/dual-process-theory.html\">Dual Process Theory<\/a><\/td>\n<\/tr>\n<tr>\n<td>Praveen<\/td>\n<td>Math and Logic Play<\/td>\n<td><a href=\"http:\/\/math-play.blogspot.com\/2006\/09\/boy-and-storekeeper.html\">The Boy and the Storekeeper<\/a><\/td>\n<\/tr>\n<tr>\n<td>Heath Raftery<\/td>\n<td>Killing Mind<\/td>\n<td><a href=\"http:\/\/heath.hrsoftworks.net\/archives\/000073.html\">The Results are in!<\/a><\/td>\n<\/tr>\n<tr>\n<td>Alun Salt<\/td>\n<td>i-Science<\/td>\n<td><a href=\"http:\/\/iscience.wordpress.com\/2007\/02\/17\/roman-camps\/\">The Orientation of Roman Camps<\/a><\/td>\n<\/tr>\n<tr>\n<td>Scott<\/td>\n<td>Grey Matters<\/td>\n<td><a href=\"http:\/\/headinside.blogspot.com\/2005\/06\/40-30s-4-15.html\">40 30s 4 15 &#8211; playing with the 15 puzzle<\/a><\/td>\n<\/tr>\n<tr>\n<td>P.
