Golden Ratio

phi

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.

[Image of Hurricane Sandy (2012) found here. The definition of Phi is stuck in my head, but it’s also found here.]

Pendula Demonstration

Horse rocks out to crappy dance music [via].

“Welcome to Kansas: Not as Flat as Delaware!”

How to multiply numerals with multiple digits graphically. Very cool. Now I can get rid of my TI Datamath.

Sorry to have to state the obvious, but the people who marched for “Climate Change” are idiots.

Interesting timelapse of Arizona weather [via].

Planets inside water droplets.

A Tribute to Pugsley Addams.

Very cool audio/visual display of pendulum motion [via]. Visual demo of sound waves, mathematical sine wave congruences, electronics, physics, gravity, art and bowling all in one. Surprising stuff happens about 1:00 in. There’s medical info in the video as well – one of the kids has whooping cough. I haven’t heard that sound since I was in 3rd grade. [A screencap of the video is the source of the top image.]
