So, I was working with the Fibonacci sequence this afternoon, and I stumbled onto something that maybe a major discovery to geometry, I don't know if it is or not. So, I began working with the golden spiral, and began drawing it. After drawing it, I noticed you could draw circles and more circles with this sequence and spiral. The values even made sense to the circle sketches. This is what I did. Here is an image of it: http://img442.imageshack.us/img442/7633/proof1oa.png [Broken] What I did was took three numbers and inputted them into the formula I made, r1 / D + r2 / D = pi/2. The first numbers I did this to, I simply just got 2/2. Now, as I went on, the numbers became closer and closer to pi. I realized maybe if I kept going, I would reach a value, which I did. What I found maybe the reason why 22/7 works as an approximation of pi. So, I soon ended up with the diameter as 21. I did 1+1+2+3+5+8 / 21 + 13 / 21 = 3.14/2. Then, this would be 20/21 + 13 / 21. Add these fractions together, and you get 33/21, which simplified would be 11/7. If you were to multiply this by 2, you would get 22/7. I was just wondering if this work is legit or not.
