Prime Number Patterns

Prime Number Patterns is a visual representation of determining which natural numbers are prime, deficient, perfect, or abundant.

NASA MathTrax

NASA MathTrax is a graphing tool for middle school and high school students to graph equations, physics simulations or plot data files. The graphs have descriptions and sound so you can hear and read about the graph. Blind and low vision users can access visual math data and graph or experiment with equations and datasets.

An excellent image showing the scale of our solar system.

Japanese man calculates pi to 10 trillion digits

The latest number-crunching champ isn't a supercomputer--it's a hacked-together PC.

Shigeru Kondo of Iida, Nagano Prefecture, worked with software designed by Northwestern University grad student Alexander Yee, and followed up their 2010 feat of reckoning pi to 5 trillion digits.

The result was achieved earlier this month after 371 days of computation and numerous hard drive failures.

Babbage Analytical Engine designs to be digitised

A project to construct one of the earliest mechanical computers based on sketches by its designer, Charles Babbage, has received a major boost.

The Science Museum in London has agreed to help by digitising the mathematician's original plans.

Eventually the images will be used to create a full working model of the Analytical Engine.

Crazy Japanese Math

This is one way to keep kids (i.e., boys) interested in math. Too bad I can't read it.

Economy Statistics

Due to the ongoing bad economy, I decided to add a couple of statistical graphs to show that.

The Batman Equation

FRACTRAN

I came across this mathematical programming article on Wikipedia called FRACTRAN.

FRACTRAN is a Turing-complete esoteric programming language invented by the mathematician John Conway.

What an amazing methodology. I decided to buy the referenced book "Nonplussed!: Mathematical Proof of Implausible Ideas". It's easy to read, but the proof is still difficult to follow. I really need to read it again.

π = 4!

Extended Midy's Theorem

This is my proof, and an extension, of Midy's Theorem. Someone had referenced this in Wikipedia almost six years ago, but it was recently removed (still in the history) to make Wikipedia more official. Since this blog came about after my proof, I never went back and added it.

Microsoft Mathematics 4.01

Microsoft Mathematics provides a graphing calculator that plots in 2D and 3D, step-by-step equation solving, and useful tools to help students with math and science studies.

NetCalc

NetCalc.org is a prototype web-based graphic calculator aiming to provide advanced mathematical functionality. Functions can be viewed graphically, in table form and as a summary of area and mean values.

Benoît Mandelbrot, Novel Mathematician, Dies at 85

Benoît B. Mandelbrot, a maverick mathematician who developed an innovative theory of roughness and applied it to physics, biology, finance and many other fields, died on Thursday in Cambridge, Mass. He was 85.

I just came across this awesome website dedicated to all the math trivia found in The Simpsons TV show.

P vs. NP

According to Vinay Deolalikar a research scientist at HP Labs, P is not equal to NP.

His preliminary manuscript can be found here.

Sorting Algorithms

My last post on sorting algorithms had static displays. This site shows animations for all the different sorts.
