I love math, and I am not a mathematician. I am a girl. I am a girl who studied humanities and arts. I work in a field, and I have almost always worked in fields that require very very little math besides basic arithmetic come payroll time. This blog is a cultural, intellectual, foodie, drinky, sort of blog. But I’m blogging about math because I love it. I hate that math is seen as geeky and useless. There are so many beautiful patterns – things I cannot understand but can still recognize as stunning – and things that we as human beings still cannot understand. Love this stuff. I need to find an intro to number theory course – not only would it be fun, but it would keep me from doing stupid things like believing I discovered a pattern to predict prime numbers. I won’t keep rattling on and on, I promise. Just take a look at some of this stuff, and tell me it’s not extremely awesome. Makes me happy to be alive.
Add the numbers in any direction, and the add up to the same amount. Magic squares have been known to people for thousands of years, and they are still amazing today. I spent a few hours today analyzing the numbers within the squares, and between different kinds of magic squares. Check this one out.
So one of the cool things I’ve discovered is that the average value of each square within a square (e.g. in the 6 square, the average value of each square is 18.5 – 111/6=18.5), compared the the average value of each square in the square one smaller (e.g. the 5 square), is halfway between the number of each of the squares’ rows. Each row in the 6 square equals 111 – so the average value of each square is 18.5. In the 5 square, each row adds up to be 65, making the average value per square 13. 18.5-13=5.5. Great. When you look at the 5 and 4 squares, the difference in average square value is 4.5. And 3.5 between the 3 and 4 squares. Isn’t that amazing? Why? What does it mean?
