BARS::AZ Hwy-80 Underpass With Speed Limit Signs in Bisbee, Arizona

These highway signs are in Bisbee, Arizona. MathBabbler took this picture while staying in Bisbee for Pi Day 2011.

The highway signs say...

   +------------+ +--------------+ +------------+
   | AZ 80 West | | 16 FT - 6 IN | | AZ 80 East |
   | Old Bisbee | +--------------+ |   Douglas  |
   +------------+                  +------------+
   +-------+                            +-------+
   | Speed |                            | Speed |
   | Limit |                            | Limit |
   |   25  |                            |   25  |
   +-------+                            +-------+

   the numbers are:  80  16  6  80  25  25

   the math is:  80 / (80 / 16) - 6 - sqrt(25) = sqrt(25)

   more math:  80 / sqrt(25) * sqrt(80 / sqrt(25)) = (sqrt(sqrt(16))^6

   more math:  6 - 80 / 80 - 25 / 25 = sqrt(16)

   more math:  16^(80 - 80) = 6^(25 - 25)

   rsPhiEval:  ((80/80 + sqrt(25 / sqrt(25))) / (6 - sqrt(16)) = Phi
   * Phi is the golden ratio and it approximates 1.61803399

   rsStateEval:  
      cuberoot(sqrt(80 - 80 / sqrt(25))) * 6! / sqrt(25)! * sqrt(16) = 48
      * Arizona was the 48th state admitted to the Union.

MathBabbler visited Bisbee during June of 2007 and he took a picture that excluded the speed limit signs and during July of 2007 MathBabbler posted MathBABs.us::BARS::AZ Hwy-80 Underpass in Bisbee, Arizona
