a small project (July 5, 2018)

I am looking for an example that will help us understand the relationship between Cartesian coordinates and Cayley coordinates. Let’s first consider all the configurations in space of a ring made of four sticks of known lengths, with points A,B,C,D in order.  We...

Some starting projects (June 13)

Project 1: The tetrahelix turns out to be a sequence of points H(n)= (r cos(theta n),r sin(theta n), m n) on a helix, where the constants r, theta, m should be determined by the requirement that each edge of the tetrahedron H(n) H(n+1) H(n+2) H(n+3) has length 1.  ...
