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.

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.

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.
