The Psychology Contrarian II: The Obsession with IQ

At best, these websites present these people as numbers first, people second. To what extent does saying that Marie Curie has an IQ of 190 or so add to or take away from her discovery of radioactivity or her other contributions to Chemistry and Physics to which she literally paid for with her life, all […]

The Psychology Contrarian I: The obsession with IQ

When there are no serious researchers that would place any relevance on IQ and what it measures (indeed, what exactly is it measuring is itself a mystery: does intelligence even have a definition, or am I missing out on something?), I wonder why there are web sites which even go so far as to go […]

Zero

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 calendar created 600 years previous […]

After another crisis, we’re back on the air!

Things were popping in terms of hit counts in the past few weeks, but crapped out when I had to upgrade to a different WordPress version. It turns out I had a corrupt index.php file (2 megs, which is kind of large for a file that should be all of 400 bytes) (397 to be […]

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 bought new anymore. I have […]

A very creative video

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 […]

Magic Squares: Errata

There were some mistakes with the construction of the odd-ordered 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 […]

Recreational Math I: Magic Squares: the “really good” kind – Part 7

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 […]

A Little Late to the Party: The B. S. Generator

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 how I am e-enabled to […]

Recreational Math I: Magic Squares: the “really good” kind – Part 6

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” properties which I called the […]

Recreational Math I: 4×4 squares: Some sequences work better than others

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 […]

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, and probably longer in other […]

Recreational Math I: Magic Squares: the “really good” kind – Part 3

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.

This is a small part of a 1514 engraving by Albrecht Durer, called Melancholia. The author of the […]

Recreational Math I: Magic Squares: the “really good” kind – Part 2

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 is “magic”, I mean that […]

Recreational Math I: Magic Squares: the “really good” kind

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 […]

Getting f(x) notation to work in Maple

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 + […]

The Theme of the Journal has Changed

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 […]

Crappy Album Covers #327 — Already knowing your cover is crappy

I don’t know about you, but this album, by El Tadeo, is being sold by everybody from Napster to Amazon to websites as far-removed 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. […]
