Math Monday: Mathematical beading

By George Hart for the Museum of Mathematics


Beading is a traditional craft which recently has been applied to make interesting mathematical models. Here are some impressive examples by Bih-Yaw Jin, starting with a beaded Mobius strip.


A beaded helical surface twists through space like a cork screw.


All five Platonic solids are shown here, using beads for their edges: octahedron, cube, tetrahedron, icosahedron, and dodecahedron.
