Item details

Handmade item

Made to order

Material

steel

Two lines meet at a single point. An equal number of new points is evenly distributed along both lines. For each corresponding pair of points a new line is drawn connecting them. This sounds like a complex and tedious process but it is, in fact, a simple exploration of geometry performed by artists, engineers, and doodlers all over the world. Every line in our diagram represents a point of tangency to the same parabolic curve. This unique property of geometry helps form the basis of our understanding of parabolas and complex curvature.

A favorite of bored students everywhere, the beautiful form of these parabolic tangency diagrams is now available as an elegant hook. Perfect for coats or keys or even a hat if you're daring enough.

Made of stainless steel, attaches with a single #8 (or 4mm if you prefer) screw.

    Good shipping time and great packaging! I've received larger 3D printed objects for cheaper, so I'm still trying to figure out if it's WORTH the price, but the vendor was very responsive and nice, so FULL POINTS for that. They also threw in a little gift, which I super appreciated. It make me really happy :) And these certainly work and roll between two flat surfaces smoothly! The math and science nerd side of me keeps poking its head up through the strongly arts and language ocean whenever I look at these :D

    This cuff goes with everything. It is exactly what I was looking for. I love the details and the artistic design. It feels really solid. I can see it is great for women and men, which is very hard to find in jewelry.
