So (if you don't mind sharing) what's your plan of action with the thread? You could generalize the worldline concept into multiple dimensions, but that doesn't seem like your style. Include more on the nature of this method? Springboard straight into relativity?

Straight into relativity. After the concept of spacetime itself, I plan to introduce the Minkowski metric and derive the Lorentz transformation directly from it. It's not as hard as it might sound--it is a hyperbolic rotation, the reasons for it being so being quite natural. That is why I included rotations and hyperbolic trigonometric functions in the math review. I will generalize to more than 1+1-dimension, but not for a while yet.

I really ought to get back to writing that. Right now, problems involving series are distracting me--but you ought to find that series-extraction method I've posted in the math guild interesting. It can be easily framed in terms of linear algebra.

Very nice. I'll look out for it. Going into multivariable (generalized) analysis next semester, I'm always happy to get a head start.

After seeing this, I'm actually ashamed of the treatment of special relativity I've been given. Basically, we said that "Light travels the same speed in all reference frames" and algebraically derived the Lorentz transformations. Honestly? Not all that interesting. But it was required for the EM class, so that you can derive magnetism from electricity.

I wish I had Prof. Callan for that class...but he taught the level below mine stressed

I saw your intro to special relativity !~!

I'm rather excited about it, as I read all sorts of articles all the time, and I maintain a very minimal understanding of all of it (reading string theory, about black holes, etc.)...
As I've only taken up to Pre-Calc. I stopped and decided no against AP Calc.

Senior year.
Stress from previous year.

Woulda failed. ;D


BUT I WOULD LOVE TO SEE THIS FINISHED!


Edit:
My course of math in the years went as this: 6th grade, pre-alg 7th; Geo, 8; Alg 9;Alg 2 (Or Adv. Alg) 10; FST (Functions Statistics Trignometry) 11: Pre-Calc.

The intro has merit but I think that especially if the goal is to have an easily accessible introduction to it from the perspective of high school mathematics something a little simpler is in order. I remember seeing a very simple demonstration of special relativty in one of my books that not only used nothing more than high school mathematics but nothing more complex than the pythagorean theorem. I think something like that would probably be a good place to start with. The rotation view is probably more intuitive but the math is more basic starting from the perspective of different frames of reference.

What you have so far looks promising. It's hard for me to think back to high school level, but I don't anticipate there being too large of gaps of understanding, as you seemed to cover fairly thoroughly in basic terms.

My only suggestion might be to include a phrasing of the principle of relativity (We require the laws of physics to hold the same for observers in inertial reference frames) as well as perhaps a brief foray into some of Maxwell's equations, as a way to motivate why special relativity was developed. It's fully possibly, however, that you already have plans for that.
