“The world yearns. This is its sure gravity: the attraction of bodies. Earth for molten star. Moon for earth. A hand for the orb of a breast. This is its movement too: the motion of desire, of a longing toward.”

“If seeds in the black earth can turn into such beautiful roses, what might not the heart of man become in its long journey toward the stars?”

“So when he touched me, it was deeper and slower than the wildfire, like the flow of molten rock far beneath the surface of the earth. Too deep to feel the heat of it, but it moved inexorably, changing the very foundations of the world with its advance.”

“It was the tiredness of time lived, with its days and days. It was the tiredness of gravity- gravity, which wants you down in the center of the earth.”

“Deep under our feet the Earth holds its molten breath, while the bones of countless generations watch us and wait.”

“His laws changed all of physics and astronomy. His laws made it possible to calculate the mass of the sun and planets. The way it's done is immensely beautiful. If you know the orbital period of any planet, say, Jupiter or the Earth and you know its distance to the Sun; you can calculate the mass of the Sun. Doesn't this sound like magic?We can carry this one step further - if you know the orbital period of one of Jupiter's bright moons, discovered by Galileo in 1609, and you know the distance between Jupiter and that moon, you can calculate the mass of Jupiter. Therefore, if you know the orbital period of the moon around the Earth (it's 27.32 days), and you know the mean distance between the Earth and the moon (it's about 200,039 miles), then you can calculate to a high degree of accuracy the mass of the Earth. … But Newton's laws reach far beyond our solar system. They dictate and explain the motion of stars, binary stars, star clusters, galaxies and even clusters of galaxies. And Newton's laws deserve credit for the 20th century discovery of what we call dark matter. His laws are beautiful. Breathtakingly simple and incredibly powerful at the same time. They explain so much and the range of phenomena they clarify is mind boggling. By bringing together the physics of motion, of interaction between objects and of planetary movements, Newton brought a new kind of order to astronomical measurements, showing how, what had been a jumble of confused observations made through the centuries were all interconnected.”
