Sewing in Math–Parabolic Curves
March 31, 2016
I learned that you can make lots of different designs with just a few nails, some string, and a board. Math is in it when you go from one at the top to one at the bottom, two at the top to two at the bottom, and then when you get to ten at the top and the bottom, it makes the curve.
I almost chose that one too.
