Even the ratio of the width to height of all credit cards equals Phi (which is 1 plus the square root of 5 divided by 2). The best website on the subject is http://www.mcs.surrey.ac.uk/Personal/R.Knott/Fibonacci/. Another interesting one regarding the face is http://goldennumber.net/face.htm.Every good math teacher should be teaching about phi. There are many examples of phi in nature as well as (hu)man-made things which we use daily. I just thought about paper sizes, and realize that Ledger size (11"x17") paper and 3"x5" photo paper, are based on phi.
