What is algebra? happens in square (flat or two dimensional) space if we introduce the reliationship of 1 to 2 to the relationship of 1 to 4?
A sphere can also be defined as the surface formed by rotating a circle about any diameter. If the circle is replaced by an ellipse, and rotated about the major axis, the shape becomes a prolate spheroid, rotated about the minor axis, an oblate spheroid.
