• ID Code: A2-15
  • Purpose: Approximate the hyperboloid
  • Description:

    Twist the two spools in opposite directions to produce a changing hyperbola. Hold heavy string taut across hyperbola as shown in the photograph. This can help students to relate concepts of multivariate calculus and three-dimensional geometry.

    This device can also be used as a model of light propagation in relativistic space-time.
