Proof of the Week: Introduction

I’ve decided to try to do a weekly feature called “Proof of the Week,” where I’ll explain a mathematical proof that I find particularly illuminating or intriguing. Part of the reason that I write so many math posts on this blog is that I feel that much of the beauty of math is an acquired taste. So my desire is to help serve as a “waiter” who introduces people to some of the fascinating tidbits of the subject. I know a lot of people who run (or roll their eyes) when they hear the word “math.” It brings back terrifying memories of grade school multiplication tests and what not. I don’t blame you. My fourth grade math teacher used to slam a book shut at the end of every minute long mad-dash times test. It scared the bejeus out of me every time. Even so, I still love math.

Most of the proofs I’ll be talking about from week to week won’t be overly intense. I’m sure that many of them will require some general knowledge background, but nothing too academic. My hope is that by explaining some interesting results that you too might see a little bit more of the grandeur contained in this subject. I remember when I took my first proof-based math class during my sophomore year of college. I knew that a lot of rigorous math had to do with proofs, but it wasn’t until my 20th year of life on this planet that I learned what they were really all about. And here’s one of the many revelations I came to rather quickly:

Math is nowhere near as objective as I thought it was growing up. In other words, I always thought that there was a unique answer to every problem. Because of this, I think that many people regard math as some sort of rigid 60 year old person wearing starched clothing who eats the exact same three meals a day and whose house is painted a single shade of grey. To use another image, many people view math problems as some sort of assembly line. You insert a problem at the beginning of the line, perform a bunch of robotic methods, and the answer plops out at the end of the line. If this is your view of math, no wonder you think it’s boring! There’s no art in these images. There’s no movement or color in these pictures.

Math is nowhere near as simple as an assembly line. At least not at its heart. But since most of us grow up learning rote methods to solve problems many of us find the subject to be too tedious or mundane. And I don’t blame you for thinking that. What I WOULD like for you to consider is that you’ve been misled. Like any other academic discipline, math is a growing organism. Hopefully in these “Proofs of the Week” I’ll be able to illuminate some of the beauty that is contained in math. The first of the series will be up in a day or two. Stay tuned!
