To an observer situated on the moon or on one of the planets, the most noticeable feature on the surface of our globe would no doubt be the large areas covered by oceanic water. The sunlit face of the earth would appear to shine by the light diffused back into space from the land and water-covered areas.
C. V. Raman
When we consider the fact that nearly three-quarters of the surface of the globe is covered by oceanic water, we begin to realise that the molecular scattering of light in liquids may possess an astronomical significance, in fact contribute in an important degree to the observed albedo of the earth.
C. V. Raman
It is absurd to assume that upon the rigid earth-crust the organic originated from the inorganic. In order to explain the nascence of the lowest organisms on the earth-crust, one must assume an already existing organising principle or a thought-process, under conditions that would render organic combinations impossible. We must accordingly assume that these conditions are valid only for the life-process in the actual state of the earth's surface, and only so far as we can explain them may we estimate the possibility of life-processes under other conditions.
Bernhard Riemann
Better be careful, Jason warned himself. Why should I be careful? A nagging thought just below the surface of his mind gave him an uneasy feeling again, the feeling that something was wrong, that things were not what they seemed. Was that his imagination or just being in this small office, no air-conditioning, not even an electric fan? For some reason, the blank walls bothered him. No pictures. And no windows. I want to get out of here.

I want to get out of here. He realized that he could get out of there. He could simply get up and leave. He didn't have to even speak to anybody. Hadn't they said this was voluntary? He was a volunteer. Well, he didn't feel like being a volunteer anymore. He wanted to go home.

Proposition 1. Two equal spheres are comprehended by one and the same cylinder, and two unequal spheres by one and the same cone which has its vertex in the direction of the lesser sphere; and the straight line drawn through the centres of the spheres is at right angles to each of the circles in which the surface of the cylinder, or of the cone, touches the spheres.
Aristarchus of Samos
Roll a ball under your hand on a table and roll a pencil in the same manner. What you feel are "point" and "line" bearings. But to understand what mechanics mean by a surface "bearing," grasp a pencil in your hand and use your other hand to make it turn as a piece of shafting. Now, the lower half of the shaft is supported everywhere by contact with your hand - the upper half is not supported, merely covered. The advantages of ball and roller bearings were obvious many years ago to mechanical people... Solid steel rollers, being inflexible, were not satisfactory at that stage, but a Hyatt flexible roller bearing was different. We had something. Our spirally wound tube roller had a springlike quality, yielded to irregularities caused by poor manufacture, thus making automatic adjustments between housing and bearing.
Alfred P. Sloan
Though the river's current never fails, the water passing, moment by moment, is never the same. Where the current pools, bubbles form on the surface, bursting and disappearing as others rise to replace them, none lasting long. In this world, people and their dwelling places are like that, always changing.
Kamo no Chōmei
The strength that we want is not a brute, unregulated strength; the beauty that we want is no mere surface beauty; but we want a beauty on the surface of life that is from the central force of principle within, as the beauty on the cheek of health is from the central force at the heart.
Mark Hopkins
The treatises of Darboux (1842–1917) and Bianchi (1856–1928) on surface theory are among the great works in the mathematical literature. They are: G. Darboux, Théorie générale des surfaces, Tome 1 (1887), 2 (1888), 3 (1894), 4 (1896), and later editions and reprints. L. Bianchi. Lezioni di Geometria Differenziale, Pisa 1894; German translation by Lukat, Lehrbuch der Differentialgeometrie, 1899. The subject is basically local surface theory.

And if God does not help me to go on, then I shall have to help God. - The surface of the earth is gradually turning into one great prison camp, and soon there will be nobody left outside. ... I don't fool myself about the real state of affairs, and I've even dropped the pretense that I'm out to help others. I shall merely try to help God as best I can, and if I succeed in doing that, then I shall be of use to others as well. But I mustn't have heroic illusions about that either.
