The Beauty of Mathematics
In this short film, we see three panels. At left, an equation or set of data. In the center, a diagram visualizing the left panel. At right, video showing an example in the real world of the thing being visualized. On the one hand, it's simply a beautiful thing to watch; on the other, it's a bit of a test to see if you recognize the math (or physics, or chemistry) of what's being represented. I'll admit that the closest to my heart was the HTML example, where the binary at left seemed fake-o, but that's okay. A close second was the compass. See if you recognize these:
Special Math-Geek Easter Egg: The aspect ratio of this video is 3.14:1. Nice work, filmmakers Yann Pineill and Nicolas Lefaucheux!
