Modern Physics & Magic: A Few Words

This originally appeared on the Fantasy, Futuristic & Paranormal RWA chapter blog.

I’d like to take a few minutes today to talk about modern physics and magic (or magick,  if that’s your preferred spelling).

Now I know you already think I’m crazy, but hang on for a minute. Because I have a few words that I think you might find interesting.

The first one is “Fields”

Specifically, the electromagnetic fields of protons and electrons. They’re why we perceive matter as solid, even though the average atom is mostly empty space.

The not-empty part is a nucleus of protons and neutrons with some number of electrons wandering around at various distances and configurations that can be predicted via quantum mechanics.  The number of electrons depends on the number of protons in the nucleus and the ionic state of the atom.

Molecules are atoms linked together with more empty space between, but they can also merge the fields of their individual atoms to create even stronger fields.

If you’ve ever tried to stick two “North” ends of bar magnets together (or ridden a mag-lev train), you have an idea of what I’m talking about. The closer together you get the magnets, the stronger the fields become.

What happens when you can negate the EM field of matter? You walk through walls and sink though floors, unless you can also negate a gravitational field and fly. Magic.

The second word is “Phase”

When light bounces off a surface, the wave (light is both waves and particle streams), the phase of the wave is shifted by 180 degrees.  Now, if you mix two waves of opposite phases, they cancel each other.  From this we get noise-canceling headphones and the possibility of invisibility.

But wait, there’s more.

If you expand the thought to quantum phases, you can end up with the multiverse – different realities that could exist alongside ours, but instead of having possible electron spins of Up and Down, their quantum phase has electron spins of Left and Right.

What happens when two universes occupying the same space but with different quantum phases experience quantum phase drift? Maybe we start seeing things that aren’t really there. Almost like ghosts.

The third word is “Entanglement”

Say you have a pair of big particles, like electrons (or even as big as microdiamonds, according to some people), that interact and are then separated.

Now the electrons have a description that is indefinite in terms of stuff like position, momentum, spin, and even polarization; when they interact they adopt opposite spins. Until you look at one to determine its spin, you don’t know what it is. And if you change the spin of an electron that is entangled, you can change the spin of the electron it interacted with, even if that other electron is at the other end of the universe. Magic.

Those are only three of the words that link modern physics to magic. If you want to know some of the others, I’m teaching an online workshop in August through FF&P that explains the concepts without going into the math.

Footnote: The math is weird; it doesn’t use numbers because pretty much nobody knows what the numbers are. Einstein, in his general relativity derivation, divided by zero at least once, which was found by someone else. And he still came up with his famous equation relating energy to mass.

In closing, I want to leave you with a few more words, these from Sir Arthur C. Clarke, the science fiction writer (which is a bit like calling Einstein the patent clerk). This is Clarke’s Third Law, written as a footnote to Clarke’s Second Law in the essay “Hazards of Prophecy: The Failure of Imagination” in the collection Profiles of the Future (added, I believe, in the 1973 edition):  “Any sufficiently advanced technology is indistinguishable from magic.”

And, lastly, the Roberts (that’s me) corollary to the Third Law: “Why choose?”

Public Service Announcement

Just popping in for a moment to say: My class Practical Chemistry for Writers starts up tomorrow so I’ll most likely be a bit sparse for the next week or so.

On the other hand, I finished judging my entries for the On the Far Side contest organized by the RWA Fantasy, Futuristic and Paranormal chapter–a week before the deadline. Ahhh, the feeling of accomplishment.

And now, back to my work in progress….

So I’m Teaching This Class…

I’m teaching Practical Chemistry for Writers as the first Murder in the Grove online class. This is a reprise of the class I taught through RWA KOD’s COFFIN program last year (with a couple of easter eggs they didn’t get). It’s also probably the last time I’ll teach this class for the foreseeable future.

Practical Chemistry will cover:
* Poison 101 – the basics
* Poison 102 – overview of alkaloids
* Meanwhile Back at the Lab – how we handled things in my lab
* Herbal Medicine that Really Works
* Suburban Terrorism – what HSA won’t tell you
* Love Potion #1 – neurochemistry of attraction, infatuation & attachment
* Soapmaking
* Distillation (making good brandy out of bad wine)

You can find more information (or sign up for the class, hint hint) at http://www.murderinthegrove.com

Feel free to forward this information wherever you think it might be useful or welcome.

Thanks,
Val Robertson
