Some interesting blogs and websites These are a small (but growing) list of nonCAC blogs:

By strider, on February 17th, 2011 I like the latest technologies as much as anyone. As I type this, I am using a Bravia hooked up to a quadcore PC using an HDMI cable, and have it hooked up to the ‘net with a wifi connection. And I know that most of my equipment can’t be bought new anymore. I have […]

By strider, on February 14th, 2011 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 you. You may click in […]

By strider, on February 13th, 2011 There were some mistakes with the construction of the oddordered magic squares. These mistakes ought to give us hope in finding squares that, if n is odd, you will indeed get (n!)2 magic squares with a random method. I had always maintained that, and until now I never had a reason to question it. And […]

By strider, on February 9th, 2011 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 known elements, and the number […]

By strider, on February 7th, 2011 Yes, Bulls**t generator technology in its many forms and guises such as this site, using a cuttingedge convergence of certain verbs, nouns, and adjectives, has assembled compelling verbal deliverables using distributed frontend generators and extensible, enterpriselevel methodologies to merge words into a confluent, innovative passage of meaningless web content. See how I am eenabled to […]

By strider, on February 5th, 2011 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 “hypermagical” properties which I called the […]

By strider, on February 2nd, 2011 I was experimenting with Danny Dawson’s 4×4 magic square script, and began to consider writing my own script. But I just thought I would do a few runs for my own research. I wanted to thank Mr. Dawson for his fine work which I am obviously gaining knowledge from, but his comments page thought I […]

By strider, on January 29th, 2011 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 in other […]

By strider, on January 26th, 2011 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 of the […]

By strider, on January 22nd, 2011 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, and diagonals […]

By strider, on January 19th, 2011 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 to doing seemingly less […]

By strider, on January 14th, 2011 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), f(x + […]

By strider, on January 10th, 2011 Times are changing at Strider’s Journal, and the time has come to retire the Crappy Album Cover series. After 329 posts and some 700 album covers, I think the time has come to put the topic to rest and move on.
That doesn’t mean that anyone coming here will no longer find the occasional article […]

By strider, on January 8th, 2011 Hey,and I thought I was the only one with a collection of mathematical music. Now, is my time to shine, and make millions! Now, courtesy of Strider’s Records, comes this great collection of mathematical ditties! Using various trigonometric equations, a waveform is fed into a sequencer, where you get the following 16 second hits […]

By strider, on January 5th, 2011 Here are the Brady Bunch’s Marcia and Peter Brady (for real). Chris Knight and Maureen McCormick got together to make an album some time after the series ended.Maureen did a string of Bmovies along with several cameo appearances on television, and was going through a rough time in her career for a couple of […]

By strider, on January 1st, 2011 I don’t know about you, but this album, by El Tadeo, is being sold by everybody from Napster to Amazon to websites as farremoved as Japan. The reason I am sure it sells so well, is because this is a comedy album with explicit content, which is dull if all you know is English. […]

By strider, on December 29th, 2010 80s newwave reggae/dance superstars The Police released this 1978 single, about suicide, called “Can’t Stand Losing You” (from their debut album Outlandos D’Amour) and featured the wellknown lineup of Sting, Andy Summers, and Stewart Copeland, who all formed respectable music careers in their own right.
As you would have guessed, the cover created some […]

By strider, on December 27th, 2010 Another in a series of highlycirculated videos. Somewhere off the coast of Ireland in the North Atlantic, a large, fullyarmed ship tries to avoid a collision with something on its radar which it thinks is another ship. They make radio contact, and find this smartalecky Irish dude on the other end. American bravado versus Irish […]

By strider, on December 25th, 2010 One knows that Yoko must have been going though a creative slump back in 1991 when Ryko released this EP. It’s hard to fathom who would spend their Christmas putting this one in their CD player. … Unless, of course, this 2006 Billy Idol album was their only alternative. He should have released this […]

By strider, on December 22nd, 2010 Some covers are ugly for a reason. This one’s ugly because it’s a bootleg of a live concert in Philadelphia by the Danish heavy metallers Mercyful Fate. Bootlegs normally have substandard covers done by someone who did not understand the fine line between scary and ugly. You can listen to this bootleg for free […]
