Description:

The fact that a rotating pool of liquid takes on a paraboloidal shape can be exploited to create a reflecting mirror for a telescope. The mathematics is presented for the reader to understand how rotation produces a paraboloid, the same shape assumed by a dish antenna.

Reviewer Comments:

This resource uses diagrams, equations and explanations to demonstrate the paraboliodal shape of a rotating pool of liquid. Necessary terms are defined and explained. Corresponding diagrams provide visual support for the argument. A background in trigonometry, physics and calculus is needed for compete understanding.
