Pi as a ratio

Exactly ...

(sorry for the pun)

Pi is indeed an exact number, even if we can't represent it in digits.

The same is true for other irrational numbers. Just because we can't exactly represent the square root of 2 (which as I recall is approximately 1.4142136) doesn't mean that it's not an exact value.

Also, we might remember that a number that we can clearly write in one numbering system cannot be as cleanly written in another system.

What if we used the number of hours in a day to represent our numbering base? Base 10 means that we can write fractions like 1/2, 1/5, and 1/10 cleanly (.5, .2, .1), but fractions like 1/3, 1/6 and 1/12 are repeating digits when written out in numeric form (I hesitate to say 'in decimal form') and they require an infinite number of digits to represent exactly (except that mathematicians take the 'shorthand' of putting a bar over the digits to represent the part that infinitely repeats.

in base 24, 1/2 would still be a clean fraction, but so would 1/3, 1/6 and 1/12. But 1/5 would become an unclean number, requiring an infinite number of digits to exactly represent.

Perhaps base 24 would make more sense, because you can get exact fractions more easily, but we could no longer count on our fingers, we'd have to use fingers, toes plus our two legs and two arms to reach 24.

That is, I think, why there are 360 degrees in a circle, because there are many more useful fractions of the circle that can be exactly represented, so perhaps we should think of base360 as being even more closely related to the infinite presence or infinite spirit. All of these fractions can be exactly represented in base360: 1/2, 1/3, 1/4, 1/5, 1/6, 1/8, 1/9, 1/10, 1/12, 1/15, 1/18, 1/20, 1/24, 1/30, 1/36, 1/40, 1/45, 1/60, 1/72, 1/90, 1/120, 1/180 and 1/360.

So, just because pi cannot be written out EXACTLY in decimal form does not mean that it is not an exact number. As one of my math friends used to say, "God knows pi exactly, we are not capable of knowing its exact value ... NOT YET!"

In another vein, we could extend that to say that God knows us exactly, even though we are not capable of knowing him exactly, at least not yet.

Look no further. http://www.spiritual-dvds-every-month.com/

I checked out one month's worth of DVDs and loved every minute. And I
really appreciated the fact that they didn't try to promote just one
point of view.
