## Oxford Mathematician explains SIR Travelling Wave disease model for COVID-19 (Coronavirus)

The SIR model is one of the simplest ways to understand the spread of a disease such as COVID-19 (Coronavirus) through a population. Allowing the movement of populations makes the model slightly more realistic and results in ‘Travelling Wave’ solutions.

The SIR model is one of the simplest disease models we have to explain the spread of a virus through a population.

## Geomancy and Thaumaturgy: Creating a Lo Shu Magic Square in Python

I am not a ceremonial magician; however, I practice Alchemy, Geomancy, and Thaumaturgy. There was a discussion on Thaumaturgy and how it relates to classical medieval figures such as Agrippa and John Dee. That conversation between zsd23 and I can be found here. I go in-depth on the mathematical basis for John Dee. I mention Agrippa, but I don’t explain too much the algorithms he was using. Agrippa was using a class of algorithms called magic square algorithms. In the book De occulta philosophia libri tres, Agrippa mentions 7 planetary magic squares. Those magic squares form the basis of a Read More

## Magical Reality Warping and Magical Portals

Or are you going to a parallel universe which is 99.99% the same, the only difference being that the new one has the changes you desire? I wrote: Yes, this reality is shifting. DJThrow4wayyy wrote: Can you elaborate? I wrote: Shifting future probabilities is shifting future histories, so the reality that emerges is changed. You’re shifting future realities.

## Occult Shapes, Symbols, and Magical Energy

vronox wrote: I’ve always wondered about the importance of shapes in certain symbols like for example if the second pentacle of mercury has to be enclosed by a circle or could it be something like below: Would it even work? Does shape of rhombus change anything? I know it’s a stupid question but I’m just corious to what extent can you modify those symbols. I wrote: Shapes are derived from vectors and postulates, so a different shape is a different formula and vectors and thus different rays of different angles. Intuitively, think about how the shape of a mirror changes Read More
