It\u2019s not just spaghetti alla carbonara, it\u2019s the whole business of inventing dishes and preparing them. It\u2019s an analogy with many parts, and it has consequences.<\/p>\n<p>To introduce myself: I\u2019m a professional mathematician, an amateur cook and an enthusiastic eater. The ideas in this essay are distilled from years of formal reasoning, mad culinary experiments and adventurous meals. In short, I\u2019ve found that:<\/p>\n<ol>\n<li>I do mathematics for much the same reasons that I cook.<\/li>\n<li>I use the same problem-solving methods in math and cooking.<\/li>\n<li>I judge dishes and math papers with many of the same criteria.<\/li>\n<\/ol>\n<p>Together these observations suggest a picture of mathematics (or a picture of cooking) quite different from the popular view. The analogy is fun and the payoff is liberating.<\/p>\n<h2>My reasons<\/h2>\n<p>I am motivated in both fields by curiosity and by thrills. I grew up reading <a href=\"http:\/\/blogs.scientificamerican.com\/observations\/flexagon-but-not-forgotten\/\">Martin Gardner<\/a>\u2019s <a href=\"http:\/\/www.scientificamerican.com\/editorial\/martin-gardner-centennial\/\">Mathematical Games<\/a> column in Scientific American. It\u2019s hard to describe how exciting these were. I read about logical paradoxes, about <a href=\"http:\/\/www.jstor.org\/stable\/10.4169\/college.math.j.43.1.002\">hexaflexagons<\/a>, about <a href=\"https:\/\/en.wikipedia.org\/wiki\/Rep-tile\">rep-tiles<\/a>, <a href=\"https:\/\/books.google.com\/books?id=orz0SDEakpYC&amp;pg=PA485&amp;lpg=PA485&amp;dq=martin+gardner+sprouts&amp;source=bl&amp;ots=wJNIkTu8t2&amp;sig=rg2KyV8QZe-PNVWlj183yrNOhtA&amp;hl=en&amp;sa=X&amp;ei=Gs6BVcGQNYGs-QHXp4Ng&amp;ved=0CCQQ6AEwAQ#v=onepage&amp;q=martin%20gardner%20sprouts&amp;f=false\">Sprouts<\/a>, and <a href=\"http:\/\/www.prometheusbooks.com\/index.php?main_page=product_info&amp;products_id=814\">Dr Matrix<\/a>. I folded flexagons, I analyzed Sprouts, I teased classmates with paradoxes. It was thrilling.<\/p>\n<p>At the same time I experienced thrills of a different sort. I remember keenly the first time my mother made apple pie. I remember the time my father grilled tuna steak. I remember the first time I tasted a whiskey sour. In all, these experiences made me what I am today: a seeker of thrills, a mathematical and gustatory glutton.<\/p>\n<p>I also play with food and mess with math to satisfy an insistent curiosity.<\/p>\n<figure class=\"align-left zoomable\"><a href=\"https:\/\/62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com\/files\/85433\/area14mp\/image-20150617-23239-h6hlva.jpg\"><img src=\"https:\/\/62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com\/files\/85433\/width237\/image-20150617-23239-h6hlva.jpg\" alt=\"\" \/><\/a><figcaption><span class=\"caption\">Where will I bounce?<\/span><br \/>\n<span class=\"attribution\"><span class=\"source\">Jim Henle<\/span>, <a class=\"license\" href=\"http:\/\/creativecommons.org\/licenses\/by\/4.0\/\">CC BY<\/a><\/span><\/figcaption><\/figure>\n<p>What happens if I combine Chartreuse and avocado?<\/p>\n<p>Where will I end up if I start in one corner of this figure and start bouncing off the sides?<\/p>\n<p>What vegetables can I caramelize?<\/p>\n<p>How much of the infinite plane can I cover with different-sized squares?<\/p>\n<figure class=\"align-center zoomable\"><a href=\"https:\/\/62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com\/files\/85434\/area14mp\/image-20150617-23223-fnpo7e.jpg\"><img src=\"https:\/\/62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com\/files\/85434\/width668\/image-20150617-23223-fnpo7e.jpg\" alt=\"\" \/><\/a><figcaption><span class=\"caption\">Squares and squares and squares on an infinite plane.<\/span><br \/>\n<span class=\"attribution\"><span class=\"source\">Jim Henle<\/span>, <a class=\"license\" href=\"http:\/\/creativecommons.org\/licenses\/by\/4.0\/\">CC BY<\/a><\/span><\/figcaption><\/figure>\n<h2>Problem-solving<\/h2>\n<p>Many books have been written about mathematical problem-solving. And many, many books have been written about cooking. But there is one single principle that is fundamental to both disciplines. It may be the only essential principle of problem-solving:<\/p>\n<blockquote><p>Make mistakes.<\/p><\/blockquote>\n<p>Make mistakes and learn from them. It\u2019s the go-to method in both fields.<\/p>\n<p>It\u2019s hard teaching this to students. They believe that mathematicians figure things out first and then act. But mathematicians don\u2019t. We jump in and mess up. It\u2019s the best way to see what\u2019s going on.<\/p>\n<p>Suppose you are asked to find a number such that tripling the number is the same as adding 12. If you know algebra, you write<\/p>\n<p>3 x n = n + 12<\/p>\n<p>and solve for n. But let\u2019s say you don\u2019t know algebra. So you jump in. You guess 10. Does that work? Tripling 10 gets you 30, but adding 12 gets you 22.<\/p>\n<p>3 x 10 = 30 10 + 12 = 22<\/p>\n<p>30 doesn\u2019t equal 22. Let\u2019s try again. Guess 12 (after all, that\u2019s a number in the problem). But tripling 12 gets you 36 and adding 12 gets you 24.<\/p>\n<p>3 x 12 = 36 12 + 12 = 24<\/p>\n<p>So 12 is worse! Let\u2019s move in the other direction. Guess 8. Tripling 8 gets you 24. Adding 12 gets you 20.<\/p>\n<p>3 x 8 = 24 8 + 12 = 20<\/p>\n<p>Closer! Maybe your next guess is 6. And if it is, you solved the problem.<\/p>\n<p>3 x 6 = 18 6 + 12 = 18<\/p>\n<figure class=\"align-right zoomable\"><a href=\"https:\/\/62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com\/files\/85426\/area14mp\/image-20150617-23256-1qjm627.jpg\"><img src=\"https:\/\/62e528761d0685343e1c-f3d1b99a743ffa4142d9d7f1978d9686.ssl.cf2.rackcdn.com\/files\/85426\/width237\/image-20150617-23256-1qjm627.jpg\" alt=\"\" \/><\/a><figcaption><span class=\"caption\">Knead that dough.<\/span><br \/>\n<span class=\"attribution\"><a class=\"source\" href=\"https:\/\/www.flickr.com\/photos\/reana\/12577820203\">TIA<\/a>, <a class=\"license\" href=\"http:\/\/creativecommons.org\/licenses\/by-nc-nd\/4.0\/\">CC BY-NC-ND<\/a><\/span><\/figcaption><\/figure>\n<p>Leaping into the unknown is also the best way to learn to cook.

What does that similarity suggest?<\/p>\n<p>Well first of all, I\u2019ve argued that the key to success in math is to make mistakes. Accepting this principle pushes you to accept a really powerful idea. If making mistakes is the key, then everyone can cook. And everyone can do mathematics.<\/p>\n<p>Second, the similarity points out that mathematics has aesthetics. Mathematicians believe this. You should too. You can pick winners (I like that math) and losers (that stuff bores me). That\u2019s what we do. I love logic and geometry. Don\u2019t ask me about statistics.<\/p>\n<p>Most students intuitively get this about history, about literature, about science. But mathematics appears different to them.
