If from the edge or equator of this lens-shaped spheroid, a ring of moderate size were cut off, it would be unlike the previous ring in this respect, that its greatest thickness would be in the line of its diameter, and not in a line at right angles to its diameter: it would be a ring shaped somewhat like a quoit, only far more slender.
"Perfesser, are yo' really an' truly goin' t' depress this elongated spheroid an' its human consignment int' that conglomerous convoluted mass of gaseous vapor regardless of th' consequences?" asked Washington, as he gazed with wide opened eyes at the sight before him.
Hence, when the larger spheroid has also a higher velocity of rotation, the relative slowness of the circulating currents, and the consequent retardation of cooling, must be much greater than is implied by the extra distances to be travelled. And now observe the correspondence between inference and fact.
Sick of my unwalled, solitary realm, I ask to change the myriad lifeless worlds I visit as mine own for one poor patch Of this dull spheroid and a little breath To shape in word or deed to serve my kind.
While the force of gravitation draws all the atoms of the spheroid together, their tangential momentum is resolvable into two parts, of which one resists gravitation. The ratio which this centrifugal force bears to gravitation, varies, other things equal, as the square of the velocity.
A search beam must have swung hurriedly aloft, for it flamed into startling being; a spheroid, compact, purposeful, dropping with breathtaking velocity. Something seemed to explode in Hilary's brain. A great cry wrenched out of his torn throat. "The Vagabond." Unbelievable, impossible. Yet he could not be mistaken. The Vagabond was coming home again! By this time the Mercutians had seen it too.
Suppose, now, that in place of an orange, which is a spheroid of very slight oblateness, we take a spheroid of very great oblateness, shaped somewhat like a lens of small convexity.
One argument certainly was in their favour: if the projectile had fallen on the earth it must have touched the terrestrial spheroid upon the 27th degree of north latitude, and, taking into account the time that had elapsed, and the earth's movement of rotation, between the 41st and 42nd degree of west longitude.
The object, Fry told newsmen, was an "ovate spheroid about thirty feet at the equator." Its outside surface was a highly polished silver with a slight violet iridescent glow. At first Fry wanted to run but his rigid technical training overrode his common, natural urges. He decided to go over to the object and see what made it tick. He circled it several times and nothing broke the desert silence.
The forms upon the surface of the globe are preserved from the influence of gravitation by the attraction of cohesion, or by chemical attraction; but if their parts had freedom of motion, they would all be levelled by this power, gravitation, and the globe would appear as a plane and smooth oblate spheroid, flattened at the poles.
