This water dept. sign is located at Gaicki Park in Tempe, Arizona.

The water dept. sign says...

+--------------------------+ | City of Tempe | | Water Dept. | | Well No. 11 | | Well ID. A(1-4) 1 C6B-11 | | PWS # 0407-100 | | 55-514694 | | Emergency No. | | 480-350-2669 | +--------------------------+the numbers are: 11 1 4 1 6 11 407 100 55 514694 480 350 2669 the math is: A = sqrt(2669 - 407 - sqrt(514694 + 480 + 350) - 11 - 11 - 1) B = 55 - ((100 - 4) / 6) A / B = 1 observe... A: 514694 + 480 + 350 = 542524 sqrt(542524) = 718 2669 - 407 - 718 - 11 - 11 - 1 = 1521 sqrt(1521) = 39 A = 39 B: 100 - 5 = 96 96 / 6 = 16 55 - 16 = 39 B = 39 The numbers 2669, 407, 514694, 480, 35, 11, 11, 1 are used to calculate A and A equals 39. the numbers are: 39 55 100 4 6 1 Phi math: (log(sqrt(100)) + sqrt(1 + 4)) / (6 - sqrt(55 - 39)) = Phi observe... Phi = golden ratio = 1.61803399 sqrt(100) = 10 log(10) = 1 sqrt(55 - 39) = sqrt(16) = 4 Pi math: (16 + 6) / ((4 - 1)! + log(sqrt(100))) = Pi observe... Pi = 3.14 [rounded to nearest hundreth]Important Note: It is not clear what the Well ID is. The '6' in C6B-11 might be a 'B'. This sign was initially interpreted by looking at the picture on the digital camera, which has minimal zooming capabilities. Upon reviewing the sign on a computer monitor, it appears as though the Well ID is CBB-11; i.e., if the sign doesn't contain a '6', the all of the aforementioned math, while arithmetically correct, is invalid.
