A recent news story was about doctors not knowing the basics of Bayes’ theorem: they were asked a basic question about false results on a disease test. A lot of them flubbed it.

Let’s be fair: I wouldn’t expect most doctors to be able to regurgitate Bayes law or do an applied example.

I would expect them to say “That question is more complex than it sounds”, rather than fall into the usual trap.

It’s the old knowing what you don’t know (and that’s for another post).

Anyway, that was the prod for me do a dive into basics of Bayesian Analysis in several parts.

I’ve exhibited at Colony of Artists several times, a vibrant art festival at Abbeyhill Colonies in Edinburgh.

One of the things I was showing and selling was my tesselation pieces: designs inspired by MC Escher’s work, particularly matamorphosing tesselations.

Some of these pieces play with negative space and the transition from 3D to 2D:

These are notes from a workshop I gave on Snare technique for Beltane 2021 (Acropolyptic).

The target audience is someone learning basic technique from the ground up, particularly in the context of processional drumming (playing a single drum). But the skills can equally apply to kit drumming etc.

Developing snare technique is hard. It can take ten hours or more practice time to start solidifying things, due to the fine motor control and muscle memory training involved.
