  1. Hyperbolic Paraboloids

    Hyperbolic paraboloids are the canonical example of a surface with a " saddle point " - a stationary point which is neither a maximum nor a minimum. At such points on surfaces, the  Gaussian curvature  is negative. Hyperbolic paraboloids...

  2. Nodoids

    A "nodoid" is another surface of revolution with constant non-zero mean curvature. It is generated by a hyperbolic catenary, which is in turn generated by rolling a hyperbola along a line, as explained in  Constant Mean Curvature . This is a...

  3. Trajectories of a Particle in a Bowl

    Model II 6 relates to the  classical mechanical problem of finding the trajectory of a point moving in space, under certain assumptions. The shape of the model is a spherical bowl, cut out by removing half of a sphere from a solid block. In...

  6. Bean-Shaped Bodies

    Mathematics is not usually considered an experimental science. However, there are many analogies between the approach to mathematical research and the more familiar experimental scientific process. While mathematicians do not usually go out...

  8. Catenoid

    Model II 3d represents a catenoid - a surface of revolution, generated by rotating a catenary curve about an axis. More concretely, a catenoid is defined by rotating the curve $z = a \cosh(x/a)$ about the $z$ axis. Catenoids are the only...
