The Earth As An Ellipsoid
Comment: early literature uses the term oblate spheroid to describe a sphere "squashed at the poles". Modern literature uses the term "ellipsoid of revolution" although the qualifying words "of revolution" are usually dropped. An ellipsoid which is not an ellipsoid of revolution is called a tri-axial ellipsoid. Spheroid and ellipsoid are used interchangeably in this article.

Famous quotes containing the word earth:
“I held a bayonet
that was for the earth of your stomach.
The belly button singing its puzzle.
The intestines winding like the alpine roads.
It was made to enter you
as you have entered me....”
