A Quote by O. Henry
Of habit, the power that keeps the earth from flying to pieces; though there is some silly theory of gravitation.

My present work concerns the problems connected with the theory of elementary particles, the theory of gravitation and cosmology and I shall be glad if I can manage to make some contribution to these important branches of science.
My opinion about Miller's experiments is the following. ... Should the positive result be confirmed, then the special theory of relativity and with it the general theory of relativity, in its current form, would be invalid. Experimentum summus judex. Only the equivalence of inertia and gravitation would remain, however, they would have to lead to a significantly different theory.
A sound Physics of the Earth should include all the primary considerations of the earth's atmosphere, of the characteristics and continual changes of the earth's external crust, and finally of the origin and development of living organisms. These considerations naturally divide the physics of the earth into three essential parts, the first being a theory of the atmosphere, or Meteorology, the second, a theory of the earth's external crust, or Hydrogeology, and the third, a theory of living organisms, or Biology.
Some claim evolution is just a theory. As if it were merely an opinion. The theory of evolution, like the theory of gravity, is a scientific fact. Evolution really happened. Accepting our kinship with all life on Earth is not only solid science. In my view, it’s also a soaring spiritual experience.
Einstein's theory of gravitation replaced Newton's, but apples did not suspend themselves in mid-air, pending the outcome. And humans evolved from apelike ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered.
I can assure you that flying saucers, given that they exist, are not constructed by any power on Earth.
I was flying planes before I was driving cars. I started gliding when I was fourteen, about when I started photographing. I was a geeky kid, and the camera was a way in high school for me to have some power. Flying was, too, I guess.
Though he avoided outright endorsement of the view, fifth-century Church Father Saint Augustine was clearly familiar with the theory of the spherical earth: "They [those who believe that "there are men on the other side of the earth"] fail to observe that even if the world is held to be global or rounded in shape, or if some process of reasoning should prove this to be the case, it would still not necessarily follow that the land on the opposite side is not covered by masses of water."
The test of science is not whether you are reasonable—there would not be much of physics if that was the case—the test is whether it works. And the great point about Newton’s theory of gravitation was that it worked, that you could actually say something about the motion of the moon without knowing very much about the constitution of the Earth.
When forced to summarize the general theory of relativity in one sentence: Time and space and gravitation have no separate existence from matter.
Without theory, practice is but routine born of habit. Theory alone can bring forth and develop the spirit of inventions.
When you hear the word 'cancer,' it's as if someone took the game of Life and tossed it in the air. All the pieces go flying. The pieces land on a new board. Everything has shifted. You don't know where to start.
The defects born of habit are innumerable. I see every child occupied in some way in disarranging and disfiguring his physique; some displace the ankles through the habit they have contracted of standing on one leg only and playing, as it were, with the other; placing it in a position which though disagreeable and strained, does not fatigue them, because the softness of their tendons and muscles lend themselves to all kinds of movement.
The man who has acquired the habit of study, though for only one hour every day in the year, and keeps to the one thing studied till it is mastered, will be startled to see the way he has made at the end of a twelvemonth.
A priori one should expect a chaotic world which cannot be grasped by the mind in any way... The kind of order created by Newton's theory of gravitation...is wholly different. Even if the axioms of the theory are proposed by man, the success of such a project presupposes a high degree of ordering of the objective world.... That is the "miracle" which is being constantly reinforced as our knowledge expands.
But the difference between the little pieces and the big pieces - I'm not actually sure which are the little pieces. With some of the big pieces, it's a lot of musical running around, whereas the little pieces, you can say everything you want to say.
