I'm sorry, I don't get it. Why is a0 = (1/4)*pi - (1/2) ? What's the argument for that?
I see that, a0 = 1/sqrt(2), but I don't get the rest.

Its flawed I found the flaw I have one more paradox paper than I wont post for awile. Ill post it later. On a compleatly unrelated note can I get a physicists opinion on this experiment

First of all, Figure B is wrong. The angular momentum vector always points the same direction and thus doesn't trace out a cone, but if you were to localize it somewhere (which is improper), it would trace out a cylinder. I can't follow the rest of your argument.

Whenever you get an inconsistency, it's because of you making a mistake. It has nothing to do with a certain brand of calculator being wrong, or the Pythagorean theorem being wrong, or whatever else you think it is. It's because you made an error.

I can't find the 'start' button on my computer... besides, I doubt the Microsoft crapulator supports RPN. If I'm sitting in front of a computer, I'll stick to "dc" for my calculator needs.

It is actually really simple and very powerful. Helps a lot if you understand RPN. After that, you do stuff like "5 4 + p" to print 5 + 4.

Yeah, RPN ftw. I mostly use my HP 49g+ if I'm doing more than a few simple calculations...

RPN is the bomb. Lots of people who do science and engineering use it.
Ive reached for my HP-48g less since Ive got an RPN calculator app on my smartphone. Otherwise, if Im on a computer Ill use a spreadsheet or mathematica for even fairly simple calculations.

Where? My dad knows it, I guess he learned it in buisness school or something, but I don't know anyone except for engineers who use it.
Seems to me that modern calculators somewhat reduce the advantages of it. I just use a calaculator that allows the entry of long expressions containing multiple terms, and that has always worked well. The display shows the entire expression as if it had been written by hand, and makes things easier to see and keep track of when doing complex problems. (the display also shows the previous operations which allows you to check for problems and recall where you are in the calculation).
TI calculators are a rip off and they bribe schools to promote their use, but I still love my TI-89.

Ugg, I hate entering long expressions like that with all the parenthesis. RPN is faster and easier than that, at least it is for those of us who like it. Its only good for algebra of course, I never feel the need to enter long algebraic expressions into a calculator. (If I do need to reduce some horrible algebraic expression, I would certainly go for my computer.)
I see RPN calculators around, in scientific and academic settings, offices and labs. Its certainly not prevalent, but you see them and recognize them as fellow users. (ThinkPads are the same way I think )

To me, the advantage is in speed and the ability to manipulate the equation I am working with on the fly. Even simple things such as adding a list of numbers is "better" in RPN. I can enter all of the numbers onto the stack, glance to ensure all the numbers I entered are correct, then hit the + button a bunch of times to perform the summation. When working complex problems, I can leave partial calculations on the stack, do some other arithmetic, then come back to where I was. When working through an equation, I think in RPN even if that isn't how I write it on paper. To me, non-RPN calculators feel clunky and odd. Sure, I can use them, just as I can still use a slide ruler, but why would I want to?
