# Solving a cubic by folding

This post, which is on my new site here: http://www.numbersandshapes.net/?p=2520 shows how a cubic equation can be solved by origami. This is not a new result by any means, but it’s hard to find a simple proof of how the

# An afternoon with Conrad Wolfram

Astute readers will notice that it’s been a very long time (five months!) since my last post. This is because I’ve been on sabbatical for this time, and not teaching. While this has been a wonderful opportunity to get to

# Meeting Julia

In my last post I mentioned the new language Julia. It deserves more than a single paragraph, so I thought I’d walk through a problem, and tackle it with the language. The problem is a stock standard one: investigating the

# The best Matlab alternative (3)

Over two years ago I wrote The best Matlab alternative with a follow-up a bit later, which seem to have engendered a far amount of discussion. Well, things have moved on in the computational world, and a user is now

# A very long-running program

In the interests of random number generation, I’ve been experimenting with the iteration for a prime and a primitive root . Now, it turns out that some primes have a primitive root which generates all non-zero residues, and others don’t.
