"Spherical" Quotes from Famous Books

... absorbed more rapidly. I made, also, three important observations. The first was, that as a general rule, the larger the bodies were, the more rapid their descent; the second, that, between two masses of equal extent, the one spherical, and the other of any other shape, the superiority in speed of descent was with the sphere; the third, that, between two masses of equal size, the one cylindrical, and the other of any other shape, the cylinder was absorbed the more slowly. Since my escape, I have had several conversations ...

... fissures would be one-hundredth the area of the land. For let us consider the strain upon a single line drawn over the summit of the protuberance from a point on its rim to a point opposite. Regarding the protuberance as a spherical swelling, the length of the arc corresponding to a chord of 100 miles and a versed sine of 3 miles is 100.24 miles; consequently the surface to reach its new position must stretch 0.24 of a mile, or ...

... the same time. A spiteful peck from nuthatch leaves him master of the morsel and the field. But the chickadee does not care. He flies down and spies a stalk of golden-rod above the snow on which there is a round object looking like a small onion. Chickadee doesn't know that this is the spherical gall of the trypeta solidaginis, but he does know that it contains a fat white grub. He knows, too, that there is a beveled passage leading to a cell in the center and that the outer end of this passage is protected by a membrane window. After some balancing and pirouetting he smashes the window ...

... from two points very remote from one another on the earth's surface. The ascertainment of these angular distances ascertained their supplements; and since the angle at the earth's centre subtended by the distance between the two places of observation was deducible by spherical trigonometry from the latitude and longitude of those places, the angle at the moon subtended by the same line became the fourth angle of a quadrilateral of which the other three angles were known. The four ...

... wades through their phantom attack indifferent. After the breeze has died the debauched old tumbleweeds are everywhere to be seen, piled up against brush, choking the ditches, filling the roads. Their beautiful spherical shapes have been frayed out so that they look sodden and weary and done up. But their seeds have been scattered abroad over ...
