Well, it’s not exactly natural, but when I walked by this construction site, the yellow netting caught my eye.
The shape of the netting definitely put me in mind of a paraboloid.
But maybe I’m just looking too hard.

Math Art: Paper Cutouts
More inspiration from the terrific MoMath talk by Erik Demaine on Math and Origami: during some explorations of the one-cut problem, a student produced this, which we all agreed was beautiful.
This isn’t the only accidental paper art we discovered.

There are only a few posts here, but they are fascinating and stunningly beautiful. I hope there are more coming!

Units Matter
As someone who has long considered himself a “pure math” person, as opposed to more of a “science” person, I never really cared much about the units of expressions; kilograms, meters, Newtons, and the like. The numbers were all I ever really cared about. Well now I see what can happen when this attitude is taken too far.
It took me about 3 days of driving around Puerto Rico before I realized that speed limits were posted in miles per hour and mile markers were posted in kilometers. Driving around a foreign country (territory?) is challenging enough without having to perform a bunch of conversions in your head.
Just to further complicate matters, plenty of signs left it open to driver interpretation.
