Snake-Arm Robot »

A series of cylinders are joined with spheres to form a snaking arm. The spheres act as hinges around which the cylinders can be turned simultaneously. The snake arm is mounted on a double boom, each part of which can be tilted separately. The entire assembly can be turned around. This arrangement is similar to that of the snake-arm robot produced by OC Robotics.

Listing's Law »

Listing's law: all eye rotations are such that they are rotations around an axis orthogonal to the primary gaze direction. Mathematically, this means the space of all eye rotations is a subgroup of the special orthogonal group SO(3).

          In quantum experiments, when we
          change our minds, we change the
          state of matter itself.  Imagine,
          how deeply our thoughts can affect
          our relationships.

Romeo and Juliet »

This Demonstration calculates the stony limits of love. More specifically, coupled differential equations describe how love varies over time using a dynamical model.
