Please do not get mad at him for spelling poorly. He spells poorly, but he is the epitome of knowledge in everything else. He's my bro, you see.

Well thank you George, I don't actually spell poorly though. I type poorly and I get in a hurry.
Kisses.

but just a note for you:
Pi is transcendental and was proven so in the 1880's by Lindemann.

Thanks for the kisses. I'm telling mom you're not taking your time again. She told you to slow down while typing.
I like your idea of how light works. I think everything is chasing its tail, tail.....ahem. Be good.

The request actually came from co-workers. It was their thinking that if anybody can solve for Pi it would be me...I understand that it's solution is transcendental (beyond human comprehension), and I'm fairly sure thats why they asked if I would try it....this was just my shot at it is all...my "rectal linear" thinking is beyond compare.

Rocket writes: There has been long standing attempts to find at which point and out to how many decimal places before Pi repeats (where does a circle overlap itself). The japanese have been runnning it on super computers for years and haven't found it. My postulation is that they won't in a two dimensional model. Still not sure what you mean. To the best of my (conventional) knowledge pi, or phi, repeating or not, are the same in any dimension.

"beyond human comprehension" is not a very good definition of transcendental...

thank you for responding again fnord. Pi has only been addressed in two (2) dimensions...on paper, with a compass and a ruler on a flat sheet of paper...there is another side of Pi...in a another dimension that we are familiar with (the "Z" axis). Pi has always been based on the "width and height" of a circle (for it to be a circle, those have to match), depth seems to have never been a consideration for some reason relative to Pi.
The theory has always been, if you can find the width and hight of a circle you can solve Pi, but never any mention of depth. The rationale for this has always been, if pi can't be resolved in 2 dimensions, it can't be resolved in 3....this is a false assumption.

I am afraid that your co-workers were probably making fun of you.
You obviously don't know what you are talking about. You don't even seem to know that Pi *is* used in three dimensions - to calculate the volume of a sphere (4/3.pi.r^3). The reasons that Pi cannot be exactly calculated have nothing to do with the number of dimensions.

I'm afraid that you misunderstand, which is understandable...I am not talking about Pi volumetrically, I'm refering to Pi in a way in which it has NEVER been expressed before...relative to the speed of light. I forgive you though, everybody tries to express it in classical terms.

Well the reason nobody has done it before is that it makes no sense. Pi is a dimensionless constant - just a numeric value.
So far as I can see the only obvious relationship is not with the speed of light but with the wavefront (assuming an omnidirectional source) - but the wavefront is simply the surface of a sphere annd is related to distance rather than speed as such.

Thanks for your explanation (not that it makes your ideas any clearer). I already thought it wasn't something conventional.
I myself am not that interested in pi (more in i, the imaginary number). Pi is "just" a non-dimensional ratio to me. There is, however, a related idea that I'm interested in. What if there were a world where the counting unity would not be 1, but another number, even an irrational one like pi? Being their unit, it would not be irrational to the people there.Instead our 1 would be irrational, and probably transcendental, to them. It would be aprox. 0.31830988... (which "happens" to be 1/pi in our world). That is, provided the pi-people would have 10pi fingers. They could find that strange number 1 by trying to calculate pi/pi etc. "1" would be as mystical to them as pi is to us. See ya.

I KNOW! Why don't we just assign random values to EVERYTHING! It would be great, you could buy a new car for fifty cents or use a rectal thermometer to check your tire pressure...you're like a genius or something.

The width and height of a circle are the same. Pi is the ratio of the circumference of a circle to its diameter. The diameter goes into the circumference approximately 3.14 times. This ratio also works with spheres, because they are pretty much 3 dimensional circles. Depth is not important to pi.
That isn't how pi is calculated though. There are a few different ways to calculate it, but the simplest is simply π = 4arctan(1), where 1 is in radians. This works out like this: 4arctan(1) = 4[1-(1/3)+(1/5)-(1/7)+(1/9)-...] ≈ 3.14159265 This is an infinite series, meaning it goes on in this pattern forever. You can use it to calculate pi as precisely as you like, but the series has to continue for a very long time before it gets accurate. This message has been edited by Gary, 07-20-2004 10:27 PM
