Detailed analysis The interface of two immiscible liquids rotating around a vertical axis is an upward-opening circular paraboloid. Source: Internet
The cavity continues to grow, eventually producing a paraboloid (bowl-shaped) crater in which the centre has been pushed down, a significant volume of material has been ejected, and a topographically elevated crater rim has been pushed up. Source: Internet
His method can be readily generalized to find the formula for the sum of any integral powers, although he did not himself do this (perhaps because he only needed the fourth power to calculate the volume of the paraboloid he was interested in). Source: Internet
The hyperbolic paraboloid structure was removed when the Denver Pavilions facility was constructed. Source: Internet
