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



Sorcerous Alchemy: Creating Enchanted Crystals with Magic

When people refer to subtle energies, they tend to be referring to ethereal, ephemeral, and intangible things – things that have no concrete substance that you effectively hold in your hand. A lot of ideas about magic propose that it is facilitated by this ethereal and intangible thing. An intuitive concept of augmenting the attributes of something (enchanting it) is to take that ethereal substance, manipulate its properties, and anchor it in some way to something such that the physical object mediates ethereal properties so that it is augmented. This is effectively like painting or gilding an object. It does Read More



Make Your Own Magical Rules

When people go about making their own magical “systems”, there tend to be two popular routes they take: making their own magical language without formalizing their ontology or they create random sigils. The problem, though, is that those two popular methods alone technically don’t create a magical system. A magical system is an abstraction comprised of a body of axioms, rules, and operations. If you were to look at classical and historical “magical systems”, you will see a formally articulated set of axioms and rules; an example of this is Western occultism. The problem with informally creating your own magical Read More



Splitting Rent with Triangles

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.


Modern Physics with Numerical Methods

This is an open-source, modern physics textbook typically for the third semester students majoring in engineering, physics or chemistry. An emphasis is placed on fundamental principles as well as numerical solutions to equations where no analytical solutions exist. The content begins with optics and uses that as a stepping stone to wave phenomena and quantum systems.


Associahedra: The Shapes of Multiplication

What happens when you multiply shapes? This is part 2 of our episode on multiplying things that aren’t numbers.


The Geometry of Causality

In this episode we dive deeper into the relationship between space and time and explore how we can geometrically map the causality of the universe and increase our understanding of how time and distance relate to one another.
