When someone utters a word that reaches your ear, the sound gets broken down into component waves via Fourier transform which vibrate within cochlear fluid and cause the movement of mechanoreceptor hair cells at the organ of Corti to produce electrochemical signals in the form of neurotransmitter release whereby the movement of the fluid stimulates the filaments of individual cells receptor cells to become open to receive the potassium-rich endolymph, causing the cell to produce an action potential which is transmitted through the spiral ganglion to the auditory portion of the vestibulo-cochlear nerve to the the brain, which signals to the cortex with new information that is then compared to predictions based on prior experience in a Bayesian fashion to produce the phenomenology of the experience of hearing, interpreting, and understanding the word. But where (and how), in all this, does the phenomenology of meaning arise?
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.
