Lie Groups Simplified: the Symmetry Underlying the Laws of Physics

The laws of physics, to the amateur science enthusiast, can sometimes seem like a disparate bunch of equations without any real underlying connection. That doesn’t seem good enough, so you dig a little deeper, and soon discover that there is this thing called Lie Theory, with Lie Groups and Lie Algebras. You want to find out what all this is, and the only things you can find just give you another bunch of equations and leave it there as if those unexplained symbols are good enough for you to understand. Well, I’m at that point, and here I am going to talk about Lie Theory and its connection to physics in hopes that explaining things simply and intuitively will help me to better understand it – and if that helps any readers understand it better, that’s good, too.

Material and Immaterial: Why Spiritualism is Untrue

This idea of a non-physical realm that transcends the physical has been a persistent one. What this even means will usually depend on who you ask. However, it usually has something to do with ethereal spirits working within arbitrary laws that have little or nothing to do with the physical laws we are familiar with. Sometimes it is the realm ghosts inhabit – the disembodied spirits of people who’ve died. Sometimes it is described more as a divine realm where angels and souls exist, somehow able to communicate actions into the physical realm when it pleases them. What spiritualism always has in common, though, is that it has everything to do with human beings.

The following post is an excerpt from a book I’m writing that has to do with human consciousness and the human condition. In this section I discuss why spiritualism is, at best, a hypothesis that should be rejected as an explanation for consciousness.
