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.

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

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.

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
You can find out how to fairly divide rent between three different people even when you don’t know the third person’s preferences! Find out how with Sperner’s Lemma.
What is a the difference between a random and a pseudorandom number? And what can pseudo random numbers allow us to do that random numbers can’t?
