Updates to Online Resource on Rotations

The online resource on rotations, http://rotations.berkeley.edu, has been operational now for nearly 3 years. Recent additions to the site include simulations of the t-handle in space that demonstrates the instability of a steady rotation of a rigid body about its intermediate axis of inertia, several simulations of tops, including the Poisson top with dynamic friction, simulations of Euler's disk, and the planar double pendulum. The newer examples on the site use Matlab’s symbolic toolbox to automatically generate the equations of motion and may be of interest to instructors for advanced engineering dynamics classes. 

On behalf of my coeditors, we hope the site is helpful to the community and welcome adding references to recent works on rotations.

Sincerely,

Oliver O'Reilly
