While looking around at Golden spirals and conspiracy theories, I found an interesting article on the History of the “Golden Ratio” and its origins. To me the most interesting part of math history is how long mathematicians have used some of these equation and theories and how many of them have endured the test of time

Many people think that the Pyramids and the Parthenon were designed with Phi in mind, but these conclusions are subject to debate. We do know for a fact that a couple thousand years ago, Phidias,Plato and Euclid had worked with Phi. They worked, just like us to apply the Golden Ratio to things in there time.

Leonardo Fibonacci born in 1175 discovered the Fibonacci sequence and its relation to Phi, which we discussed in class. Leonardo Da Vinci recognized the golden ratio or divine ratio as he referred to it. Da Vinci would use it in in work “The Last Supper”

Michael Maestlin was the first person to ever calculate the Golden ratio, his student Johannes Kepler the astronomer would also research the divine ratio. Some believe that Martin Ohm in 1815 was the first person to ever refer to the ratio as “golden” and it appears that name has stuck!
