How to Make a Random Square
I have noticed that it has been difficult to elucidate a method for systematically creating evenordered magic squares of any but the most basic kind. I don’t know why this is, since the art has been alive in Europe for at least 600 years, and probably longer […]

Notice that to show the rules for making these kind of magic squares, I used only oddordered square matrices as examples. What about matrices of even numbers of rows and columns? The rules for these vary.
This is a small part of a 1514 engraving by Albrecht Durer, called Melancholia. The author […]

Last time I introduced the idea of magic squares. I promised I would show you how to make one. In this post, I will begin by discussing “trivial” squares, or squares made by simple rules of following diagonals and wrapping.
When I say a square is “magic”, I mean that all rows, columns, […]

Maple is a robust math environment which can graph, solve equations, and solve for the unknown with the aid of its computer algebra solver (CAS), which is capable of computing exact roots of cubic functions, for example.
I wanted to demonstrate for myself that Maple could do various function transformations, such as: f(x), […]
