Do you believe in coincidences? Even ignoring the folk who see the number 11 everywhere they look, people are attracted to numerical coincidences.

Though this dates me, remember music records... they played in three speeds: 78, 45, and 33 rpm. Is it a coincidence that 78 = 45 + 33? [Note: Of course, the 33 is actually 33 1/3, or 1/3 of a 100.]

Let's continue with this theme. A CD rotates at 504 rpm, which is the reverse of 45 in a sense. Coincidence?

Or, what about the supposed connections between the golden ratio and nature? Forced or fact?
