Maybe not quite a peck.
Yet another installment from my fun with folding series.

Math Photo: Isosceles Triangle in Nature
Well, it’s sort of natural. If nothing else, it demonstrates nature’s desire for symmetry.

(Half) Parabola in Nature
I have a nice watering can with a long, straight spout. It’s good for watering tiny plants in hard-to-reach places.
It occurred to me that if I held the can so that the long spout were parallel to the ground, the water would probably come out in a parabolic path. The running water would have a horizontal velocity component, and the vertical component due to gravity would create the parabola
So I took some pictures.
And after playing around with Geogebra for a bit, I had my parabola!
This isn’t quite as pretty as this parabola in nature, but it’s more parabolic than these water spouts at the Detroit Airport.

Math Photo: Knitting the Plane
As opposed to tiling the plane, here’s knitting the plane. Or, the fence.
As you can see, they’ve still got a ways to go!
And this isn’t the first example of mathematical knitting I’ve seen: check out this knitted Klein bottle!
