BTW. nature doesn’t run on mathematics, and the typical example of a nautilus shell exhibiting the proportions of Phi has been debunked. It’s still a fun exercise, counting the seeds in a sunflower’s (or pine cone’s) spirals and dividing the larger number by the smaller to see how close it approximates Phi.
Oddly enough, if you multiply Phi by ten it gives you the approximate average miles per hour on Interstate 10 between Santa Monica and Los Angeles in either direction at any hour of the day and any day of the week. TRUE.
