Recently I've been given to an exploration of electricity and how it works, which is a bit of a challenge as to any but a well-versed electrician the whole subject is something of a squirly soup. However difficult the getting-head-around-subject may be, it's clearly important as our entire existence is hinged on electromagnetism and we can't get away from that, not in any way at all.
How electricity behaves and how technology has advanced its manipulation of this awesome power is worth delving into because once we know how things like 'lines of force' operate, we can extrapolate them into everyday life. Plainly the flow of current and the forces exerted from it are akin to the way we find our lives moving, and the illusion in electrical terms, just as in terms of life, is that there is some kind of linear component to the whole process. We think of lifetimes following a line, just as 'world line' is a phrase well-used in physics to describe the lifetime of particles. We think of the 'arrow of time' moving forwards from past to future. And we think of electric current as moving along a line through a wire in a similar fashion, starting at one point and finishing at another. The truth is that electricity relies on circuits, and no matter which power source creates it - turbines, living things, uranium - the stuff is the same stuff. The energy which keeps us alive is exactly the same energy which comes out of a nuclear plant.
The interesting thing about all this is that electromagnetism has a spectrum, from radio to gamma waves as far as we can tell with our not-very-advanced equipment. We can see a tiny slice of it in visible light, which itself ranges from infra red to ultra violet - our sight falls just short of both these wavebands. More interestingly still, the seven chakras of the human body are the colours of the rainbow in order, from base (red) to crown (violet). The system of chakras has been around a lot longer than Faraday's theories.
So here we sit, our little lives to worry about, zipping through a maelstrom of elctromagnetic circuitry which binds everything in the Universe, including our little solar system, together. I think that's really sweet. Soon it'll be time to open the cornflakes again.
