An afternoon with Conrad Wolfram

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.

The HP Prime Graphics calculator

In my effort to find the perfect CAS calculator, I recently acquired one of these babies: It has many of the hallmarks of the engineering excellence which used to be such a selling point with HP calculators: the keys are

The Casio Classpad fx-CP400

The Casio ClassPad II (fx-CP400) is the latest CAS offering from Casio: building on the previous ClassPad model to provide a calculator with a large color screen, and the ability to operate it in landscape or portrait mode. I acquired

A first look a WeBWorK

In my last post (nearly three months ago) I commented on online assessment, and in particular on Pearson’s MyMathLab Global, which we have been using for our engineering mathematics. This is quite a good, full-featured and robust package; its only
