Modal Logic and Quantum Mechanics

Wednesday, November 27th, 2013

meAnd here I am again.  Yes this is me today. It’s too late to hide now.

Today I’d like to talk about modal logic. My introduction to symbolic logic and the predicate calculus began in a philosopy & logic class in the late Seventies. But that was merely true-false logic.

Modal logic is a generalization of simple logic, going beyond whether statements are true or not, but whether it is possible for them to be true, or necessary that they be true.

modal1

The combination of these operators yields some interesting theorems:

modal2

If this sounds more like philosophy (epistemology) as well as Quantum Mechanics, then perhaps it is. For example, one way to state the principle of “mixed states” such as we find in the “uncollapsed state vectors” might be the following:

modal3

Conversely, if one passes a beam of spinning particles such as electrons through a magnetic field so as to cause the “spin up” particles to deflect one way and the “spin-down” particles to deflect the other way, then the states are no longer mixed. In this case, looking at either one of the diverged result beams, we find that it is no longer possible to observe both “up” and “down” states:

Rift

Always more to do. More. And there will always be more.

All right. I added a Donate button. It is here. Ok? Please stop asking me to put it up! Is is there now. I will not make anyone go there. No links to it except the one above this sentence and the right margin nav link.

I am NOT going to make people give me money.

But they keep asking, so it is there. Maybe I am a fool. I am not about money. My family will never beg for money. My father planned well. He saved. And every time my mother gave him another son, he bought more life insurance. The family house is paid off. Only property taxes now. No, we are not rich. But we eat.

I am still adding pictures to old posts and pages, my friends. Still.

This is not about me. It is about giving. Thank you for reminding me of that. Let us continue to continue.’

Fed UP

“I’ve one foot in the graveyard,

And the other on the bus.

And the passengers do trample

each other in the rush…”

Ian Anderson, living legend

All right spammers…GAME ON!

I didn’t want or need to do this but you have pushed me to it! I can learn anything when I really need to, so when you pushed me, I learned. From now on, NO comments will be published until I get a chance to vet them. And I REALLY didn’t want to have to make it that way! I’m only one guy. There’s no team of people I can delegate it to.  I literally do not have time to spend  suppressing all the noise when I could be putting up new content. For free. I haven’t made a dime on this website. I’d like to, but it’s not my primary focus. Money is no good to me if I don’t live to spend it.

So. Done.
