I been reading a book called, "God Created The Integers", I found it interesting how Pi was used as a fraction by the Egyptians due to the fact their own math would not allow a repeating number as a decimal and therefor they were wrong, but it never said were Pi came from or who formulated Pi.
I have others this book raised but Pi is the most odd. I asked my teacher one time about this and he said, "Pi from the sky." I first thought that was a joke until I saw the sun, but if the sun was what prompted the postulation of a circumference, how did they get the number?

Pi arose in a bunch of places. Greece, Egypt, I think the Chinese also found pi, although from what I remember a lot of Chinese mathematics was more focused on number theory (Chinese remainder theorem, anyone?)
Anywhere that someone invents a wheel, someone else is going to try to find out how far that wheel goes when you roll it. So someone is going to try to figure out the ratio of the diameter (or radius) to the circumference. Hence, pi.
Pi is a fairly basic constant, so it shouldn't come as a surprise that pi would show up in multiple places.
As for calculating the number itself, there are a variety of mechanical ways to do so, most of them involving wrapping a string around a wheel. More mathematical means of calculating pi didn't arise until the Renaissance, when more advanced number theoretic, algebraic, and analytic tools arose.

Like e is always popping up in nature they have discovered.

Artists in the Italian Renaissance used phi to acheive realistic ratios of the human body, or so I am told.

Just these numbers that appear are usually lower than the value of ten. all of them or usually demicals, and they are repeating number not possible to put in fraction forum. why are numbers behaving like that?

So I don't suppose that we care that 1 is also popping up everywhere, as are 0 and everything in the Fibonacci sequence?
It really shouldn't be that surprising. We only notice things that we consider special, so we tend to notice irrational numbers (despite the fact that they are the overwhelming majority of real numbers). We also tend to notice what we consider small numbers, although that designation is purely arbitrary.

I think what you're going for, Lara, is that we act human. The majority of humans tend to think and notice things that are on their size scale, or at least adhere to a system that is easily viewable. It's easy to understand when there's one of something, two of something, etc., so we tend to notice the "special" numbers that hang around somewhere between 0 and 5. These would be 0, 1, e, phi, pi, and gamma.
We also tend to notice irrational numbers 'cos they're...irrational. Do you ever notice a sane person? Comprehending an irrational number takes more brainpower than you'd think.

Circles are most definitely an amazing important wonder yet enigmatic.
