Fibonacci Flim Flam
I recently posted a tutorial on how to draw circles, spirals and fibonacci spirals (that pattern you see on sunflowers). I thought it would be only fair to post this critique of the notion of the “golden ratio”, in which mathematical curmudgeon Donald Simanek takes sacred geometers to task for overstating the importance and pervasiveness of the golden-ratio / golden-mean in nature.
I happen to think the golden ratio is cool, but I do agree that it is sometimes used in a numerological way which more closely resembles pseudo-science than science. You can make cool spirals with it though!
