“Let me close by reminding you of what Newton actually did on the day that he conceived G = k \frac{mm'}{r^2}. …Newton did not have any subsidies, grants, funds, Secret Service money. But he had the moon. He said, "… I cannot throw a ball round the world, but let me picture the moon as if it were a ball which has been flung around the world… How long will it take to go round the world?" …He knew the value of gravity at the earth's surface …but he did not know the value of the earth's gravity for the moon. He said, "Let us suppose that it is given by an inverse square law. Now, how long will it take the moon to go around?"”

It comes out at twenty-eight days. As Newton said, "They agreed pretty nearly."

“Let me end with… man's ageless fantasy, to fly to the moon…. Plutarch and Lucian, Ariosto and Ben Jonson wrote about it, before the days of Jules Verne and H. G. Wells and science fiction. The seventeenth century was heady with… fables about voyages to the moon. Kepler wrote one full of deep scientific ideas… wrote… The Discovery of a New World. They did not draw a line between science and fancy… they all tried to guess where… earth's gravity would stop. Only Kepler understood that gravity has no boundary, and put a law to it—… the wrong law.
All this was a few years before Isaac Newton was born, and it was all in his head that day in 1666, when he… came to conceive… that the moon is like a ball… thrown so hard that it falls exactly as fast as the horizon… he went on to calculate how long… the distant moon would take to round the earth… [T]he imagination that day chimed with nature, and made a harmony.”

“Isaac Newton only discovered the law of gravity. He didn’t invent it, did he? In the same way, the Knowledge is within you. I can reveal it. I cannot give it to you from somewhere else. … If somebody comes to me I am sure I can give him the Knowledge and he will be satisfied.”

“If so, her motion must be influenced by it; perhaps she is retained in her orbit thereby. However, though the power of gravity is not sensibly weakened in the little change of distance, at which we can place ourselves from the centre of the earth, yet it is very possible that, so high as the moon, this power may differ much in strength from what it is here. To make an estimate what might be the degree of this diminution, he considered with himself that, if the moon be retained in her orbit by the force of gravity, no doubt the primary planets are carried round the sun by the like power. And, by comparing the periods of the several planets with their distances from the sun, he found that if any power like gravity held them in their courses, its strength must decrease in the duplicate proportion of the increase of distance. This he concluded by supposing them to move in perfect circles concentrical to the sun, from which the orbits of the greatest part of them do not much differ. Supposing therefore the power of gravity, when extended to the moon, to decrease in the same manner, he computed whether that force would be sufficient to keep the moon in her orbit. In this computation, being absent from books, he took the common estimate, in use among geographers and our seamen before Norwood had measured the earth, that 60 English miles were contained in one degree of latitude on the surface of the earth. But as this is a very faulty supposition, each degree containing about 691/2 of our miles, his computation did not answer expectation; whence he concluded, that some other cause must at least join with the action of the power of gravity on the moon. On this account he laid aside, for that time, any farther thoughts upon this matter.”

“Sir Isaac Newton was asked how he discovered the law of gravity. He replied, "By thinking about it all the time.”

“In the east the moon was rising, a full moon that lighted the landscape so that he could see every little clump of bushes, every grove of trees. And as he stood there, he realized with a sudden start that the moon was full again, that it was always full, it rose with the setting of the sun and set just before the sun came up, and it was always a great pumpkin of a moon, an eternal harvest moon shining on an eternal autumn world.
The realization that this was so all at once seemed shocking. How was it that he had never noticed this before? Certainly he had been here long enough, had watched the moon often enough to have noticed it. He had been here long enough — and how long had that been, a few weeks, a few months, a year? He found he did not know. He tried to figure back and there was no way to figure back. There were no temporal landmarks. Nothing ever happened to mark one day from the next. Time flowed so smoothly and so uneventfully that it might as well stand still.”

“He’s a take-charge catcher. He bosses the player throwing the ball – I tell you, that kid amazes me.”

Roberto Clemente (1934–1972) Puerto Rican baseball player

As quoted in "The Scoreboard: Best I’ve Seen, Clemente Says of Jerry May," by Les Biederman, in The Pittsburgh Press (Tuesday, July 18, 1967), p. 59

Context: “I do not read too much these days about Jerry May, but he is worthy of a story. He is the best defensive catcher I have seen in my 13 years with the Pirates. In fact, I have not seen many better defensive catchers anywhere in my time in baseball. A story now would do him good, make him feel appreciated. How you say, the time is appropriate?" Clemente always knew May could catch but May has opened his eyes in the formidable way he blocks the plate with a runner and the ball both bearing down on him. "He’s a take-charge catcher. He bosses the player throwing the ball – I tell you, that kid amazes me."

“He did not feel that he was stealing, for the cleaver, the radio, the money, and the typewriter were all on the same level of value, all meant the same thing to him. They were the serious toys of the men who lived in the dead world of sunshine and rain he had left, the world that had condemned him, branded him guilty.”

“But some years after, a letter, which he received from Dr. Hooke, put him on inquiring what was the real figure, in which a body let fall from any high place descends, taking the motion of the earth round its axis into consideration. Such a body, having the same motion, which by the revolution of the earth the place has whence it falls, is to be considered as projected forward and at the same time drawn down to the centre of the earth. This gave occasion to his resuming his former thoughts concerning the moon, and Picard in France having lately measured the earth, by using his measures the moon appeared to be kept in her orbit purely by the power of gravity; and consequently, that this power decreases, as you recede from the centre of the earth, in the manner our author had formerly conjectured. Upon this principle he found the line described by a falling body to be an ellipsis, the centie of the earth being one focus. And the primary planets moving in such orbits round the sun, he had the satisfaction to see, that this inquiry, which he had undertaken merely out of curiosity, could be applied to the greatest purposes. Hereupon he composed near a dozen propositions, relating to the motion of the primary planets about the sun. Several years after this, some discourse he had with Dr. Halley, who at Cambridge made him a visit, engaged Sir Isaac Newton to resume again the consideration of this subject; and gave occasion to his writing the treatise, which he published under the title of Mathematical Principles of Natural Philosophy. This treatise, full of such a variety of profound inventions, was composed by him, from scarce any other materials than the few propositions before mentioned, in the space of a year and a half.”
