Callipers for finding the Golden Ratio. The golden ratio has fascinated Western intellectuals of diverse interests for at least 2,400 years: Some of the greatest mathematical minds of all ages, from Pythagoras and Euclid in ancient Greece, through the medieval Italian mathematician Leonardo of Pisa aka "Fibonacci" and the Renaissance astronomer Johannes Kepler, to present-day scientific figures such as Oxford physicist Roger Penrose, have spent endless hours over this simple ratio and its properties. But the fascination with the Golden Ratio is not confined just to mathematicians. Biologists, artists, musicians, historians, architects, psychologists, and even mystics have pondered and debated the basis of its ubiquity and appeal. In fact, it is probably fair to say that the Golden Ratio has inspired thinkers of all disciplines like no other number in the history of mathematics. - Mario Livio, The Golden Ratio: The Story of Phi, The World's Most Astonishing Number - wikipedia : http://en.wikipedia.org/wiki/Golden_ratio These need to be made in something that can be tightly joined (ie: bolted or riveted) eg, stainless steel or brass.

More information here http://www.goldenmeancalipers.com/ -- These calipers are not mass-produced. They’re lovingly hand-crafted by me… in my garage hammering the little brass rivets into place with a proper hammer, just like the proper Ancient Greeks used to do, but without the garage. -- There are three sizes, they are 1) small : 114 mm (measures 25 mm to 190 mm) : $35.00 2) medium : 180 mm (measures 35 mm to 320 mm) : $65.00 3) huge : 40 mm (measures 80 mm to 750 mm) : $75.00 I can make other sizes if requested.
