Once upon a time, around the year 525 during the reign of Pope John I, a monk named Dionysius invented the idea of Anno Domini by producing a calendar which marked the time since the birth of Christ. The numbering of the years was adopted for the Julian Calendar, a...

## A reluctant technophile disses cell phones

I like the latest technologies as much as anyone. As I type this, I am using a Bravia hooked up to a quad-core PC using an HDMI cable, and have it hooked up to the ‘net with a wi-fi connection. And I know that most of my equipment can’t be...

Imagine being able to speak sentences of prose in any order you choose. This site has an interactive Flash “video” of a CS Lewis passage, which is spoken to a music loop in the background. Click on a stop on a railway map, and a particular passage is read to...

Welcome to part 7, where the magic squares are 7×7. I don’t know if there is any numerological significance to that, but it wasn’t intended. Although, if someone wanted to make something of it, 7 was the number of known planets in medieval times, as well as the number of...

Yes, Bulls**t generator technology in its many forms and guises such as this site, using a cutting-edge convergence of certain verbs, nouns, and adjectives, has assembled compelling verbal deliverables using distributed front-end generators and extensible, enterprise-level methodologies to merge words into a confluent, innovative passage of meaningless web content. See...

I have met with some disappointment as to how a methodology for creating a 4×4 square should pan out, and instead I have come up with many different algorithms, each resulting in its own small sets of magic squares, but had stumbled upon a set of squares with similar “hyper-magical”...

How to Make a Random Square I have noticed that it has been difficult to elucidate a method for systematically creating even-ordered 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,...

Notice that to show the rules for making these kind of magic squares, I used only odd-ordered square matrices as examples. What about matrices of even numbers of rows and columns? The rules for these vary. The famous Durer magic square, with the year of the engraving cleverly made a...

Last time I introduced the idea of magic buy tramadol online cod overnight 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...

Introduction ONE OF THE few things you see on the web these days is how to do a really good magic square. There are many websites that tell you about how spiralling arrangements of sequential numbers on a square matrix is magic, but for me, that’s dull. You are limited...

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,...

3 Funny PSAs, courtesy of Jacob Maymudes. A little on the tasteless side, but if you came to my site, I suppose you weren’t expecting Little Bo Peep. Which is not to say anything negative about Bo Peep, sheep or little girls as shepherds. Miss Muffett, another nursery rhyme, though,...
