Wolfram Research introduced the this week. Here’s a simple interactive example based on some old-school pattern perception...

Read More## A day of problem solving pictures.

One of the things I love about using Mathematica is that it helps me better understand the nature of my programming and problem solving. It’s a great tool to help make sense of problems, see your errors, verify and validate your computations. Here is a set of 26 images from today’s efforts to solve a particular problem of differential geometry...

Read More## Pegged. It will come back to you?

Doing a sort of gigantic parallel computation in Mathematica. A little too gigantic, I’m afraid. Um- can IT deliver my new MacPro sooooon?...

Read More## NewGlaven

Back in 1987 I wrote some code for generating ‘noisy objects’. I cleaned up that code over the years, enhanced some calculations, played with new Mathematica features. Now I’ve got stuff that looks like this. I’ll put a reference to the paper on these things here soon....

Read More## Recurrence, heat maps, trajectories and fixations

More analysis from Dave Jacobs’ eye tracking project. We wrote all the analysis code ourselves in Mathematica. There’s a bug in the heat map compositing, but I shall procrastinate a solution soon. Lifted largely from Eye Tracking: A comprehensive guide to methods and measures. We used some ideas from Anderson’s paper on recurrence,...

Read More## Marroquin patterns

I notice that I seem to generate a lot of images while doing analysis, largely using Wolfram Research’s Mathematica… so, maybe every day I should post one of those images here- an image of something I’m working on, an “Image of the Day” (IotD) or some such. This is a “Marroquin Pattern” used by, amazingly enough,...
