A typical attempt to argue in favor of the natural origin hypothesis in the SARS-CoV-2 origins debate runs something like this:

Hundreds of thousands of viruses have come from zoonotic origins. Only a handful from labs. There’s your math problem. QED

(QED added by this author).

The problem is, even…


In the original story of this series, we investigate the properties of a square spiral through the natural numbered points of the cartesian plane. In particular, we investigated the curve to which the average of all visited points converged as the length of the spiral approached infinity. We discovered that…


In a previous story, I described how I became fascinated by the properties of a square spiral. …


At work the other day, I needed an algorithm that could visit an arbitrary number of neighbouring grid squares in a closest-neighbours-first pattern. The easiest way to do this was to enumerate a square spiral starting at the origin (0,0) and spiraling outwards.

I eventually decided on this Python procedure…


This article applies Bayesian analysis to the hypothesis that the proximal origin of SARS-CoV-2 was an uncontrolled release from a laboratory using, as evidence, one aspect of the SARS-CoV-2 origin story — where the first recorded outbreak occurred.

The goal is not to derive a single definitive estimate of the…


A tale of two DEXA scans

I have recently come to the conclusion that now I really don’t need to lose any more weight. A lot of other people came to that conclusion quite a while ago (hi Mum!), but I was prepared to push it a little further just…


This post considers the hypothesis that SARS-CoV-2 evolved from a virus that is endemic to the Indochinese Peninsula (also known as Mainland South East Asia). This is the region of the world that includes the countries: Thailand, Laos, Vietnam, Cambodia, Myanmar and Malaysia.

What is interesting about these countries is…


There are rumours that His Beloved President is feeling a touch of anxiety about the upcoming election which is also spreading like a viral pathogen amongst his most valued support base — US Senators (or that portion of that class that have not been inoculated with a clue).

So, how…


I am all for demolishing conspiracy theories and @potholer54 is very good at doing this. I am little disappointed when the bath gets thrown out with the bathwater.[1]

While there is no denying that there are some pretty lurid and nasty SARS-CoV-2 conspiracy theories out there, I think it is…


ELFS-PrV (literally, Eucalyptus Leaf Foraging Syndrome — Prong Virus) is an unusual prong virus that crossed the species barrier from possums to humans and swept through NSW in 2020. ELFS-PrV is believed to cause the rather odd Eucalyptus Leaf Foraging Syndrome in everyone that catches it, along with an incessant…
