Religiosity is a synonym of religiousness. It is a comprehensive sociological term used to refer to the aspects religious doctrine.

Brillig is a term coined by Lewis Carroll in his poem Jabberwocky which is central to his literary masterpiece Alice in Wonderland. Lewis Carroll's Alice in Wonderland, contrary to the commonly believed acid trip, was actually a harsh critique of the mathematic revolution occurring at the University where he taught. Dodgson was old school when it came to math, because right up until his time, math professors still taught from a 2,000-year-old textbook. That all began to change in the mid-1800s, when a bunch of irritating young people invaded academia and started bringing new concepts to math. Weird new concepts. Like "imaginary numbers" and other crazy stuff. What incensed Dodgson was that math no longer had any real-world grounding. He knew that you could add two apples to three apples to get five apples, but once you start thinking about the square root of -1 apples, you're living on the moon.
