This post was my response to someone who attempted to sketch out on graphing paper a system of sigils intended to manipulate mental or psychic energy. They were attempting to code and program with sigils. I wrote: It looks like you attempted to create a psychic circuit or cycle. It is very clumsy…Before I start, it is crucial that you correctly understand what circuits are. A circuit is: Traversing a graph such that not an edge is repeated but vertex can be repeated and it is closed also i.e. it is a closed trail. The second thing you should understand Read More

## 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.

## How Do Quantum States Manifest In The Classical World?

Quantum mechanics tells us that the atom’s wavefunction can be in a superposition of states – simultaneously decayed or not decayed. So is the cat’s wavefunction also in a superposition of both dead and alive.

## Magic Simplified

People frequently ask about the nature of magic, subtle energy, or psychic phenomena within occult and paranormal groups. Many paranormal communities, cultures, and pedagogies attempt to answer that question from the pragmatics and cultural frameworks of their respective paradigms. How different places and authors decide to answer these questions tends to be derived from a cultural perspective so that the answer is predicated by how cultures and communities do things. In many communities, a belief that cultural traditions predicate magic is so prevalent that many people in magical and occult communities expect people to practice some form of magic derived Read More

## Are Runes Inherently Magical?

Fearless_Oil wrote: Are runes inherently magical?… I was wondering if runes are inherently magical. If not, then why do people use them instead of making their own symbols? I wrote: No, they are not. People use them because they’re told to and it’s convenient. Fearless_Oil wrote: So from my personal understanding of magic and consciousness, something only works if you believe it works. Yet when I search this subreddit, people report greater success when using runes. Is this because people feel safer and more confident when using runes, or is it because of the reasons the person above stated? I Read More

## Telepathy, Psychic Fields, Subtle Energy, and the Afterlife

Dunabu wrote: The nature and ramifications of the “aether” by which telepathy is possible. Long story short, I’ve finally tapped into this thing, but I understand very little of its nature. What is it? All energy? Does this prove consciousness is a non-local phenomena? Is death even really real?… …By the way, anyone have any legit books or resources about telepathy/psionics? I must learn more theory and know everything!… I wrote: Dunabu wrote: …by which telepathy is possible… Does this prove consciousness is a non-local phenomena?

## Chaos IX: Chaotic or not?

There are many kinds of dynamics. Some are complicated, others are not. To try and understand this better, we can take a vector field that depends on just one parameter, and let this parameter change slowly. This shows that the dynamics, under influence of this parameter, is sometimes simple and then, without warning, becomes very complicated. We see bifurcations happening.

## Chaos VI: Chaos and the horseshoe

First, an old idea by Henri Poincaré (1854-1912): when studying a vector field in space, we can sometimes find a small disc that the trajectories hit repeatedly. Studying the points on the disc where the trajectories pass through is often a lot simpler than studying the vector field as a whole. We go from dynamics in continuous time to dynamics in discrete time.

## Chaos II: Vector fields

At the end of the 17th century, Gottfried Wilhelm Leibniz (1646-1716) and Isaac Newton (1643-1727), independently one from the other, invented a brilliant mathematical tool: infinitesimal calculus or differential and integral calculus. Read More

## Chaos I: Motion and Determinism

Chaos I: Motion and Determinism

The start of Chaos, with one of the foremost ideas of philosopher Heraclitus of Ephesis, who lived in the sixth century B.C. Creatures develop eternally, things have no substance and everything is always on the move: everything becomes everything, everything is everything. The first minutes of the film illustrate this idea with some everyday examples, as well as some mathematical ones.
