Rotating furnace
A rotating furnace is a device for making solid objects which have concave surfaces that are segments of axially symmetrical paraboloids. Usually, the objects are made of glass. The furnace makes use of the fact, which was known already to Newton, that the centrifugal-force-induced shape of the top surface of a spinning liquid is a concave paraboloid, identical to the shape of a reflecting telescope's primary focusing mirror.
Paraboloids can be used in various ways, including (after being silvered) as primary mirrors in reflecting telescopes and solar cookers.
Examples of use of rotating presidency
1. Austria currently holds the EU‘s rotating presidency.
