A common ability that you see in science fiction and fantasy is the ability to manipulate time. Marvel characters like Doctor Strange and Magik can rewind or reverse time. This ability is also seen in the Prince of Persia games. Orhime from the anime series Bleach can reverse damage and heal people and things via reversing time. Creating temporal loops is a very useful magical skill to have. It is especially useful in spells designed to reverse damage and restore the integrity of things and objects. Temporal Loops Real magical spells to manipulate temporal histories are based on loops. A Read More
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

It seems like a lot of people practice Theurgy – Enochian magic, under the impression that’s what John Dee meant by Thaumaturgy. He was referencing the idea of the archetypal “black box” where a mechanism abstractly does something Read More
If you needed to tell someone what numbers are and how they work, without using the notion of number in your answer, could you do it?
The mathematical material covered includes the basics of number theory (including unique factorization, congruences, the distribution of primes, and quadratic reciprocity) and of abstract algebra (including groups, rings, fields, and vector spaces). It also includes an introduction to discrete probability theory—this material is needed to properly treat the topics of probabilistic algorithms and cryptographic applications.
