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

The weird results of quantum experiments seem to demand weird explanations of the nature of reality.
