"Molecule" Quotes from Famous Books



... put within the grasp of man's Intelligence (if he chooses and wills) an almost infinite range in power, variety and application, of that subtle and basic Principle of affinity, balance and equilibrium, that unites the atoms in a molecule, or a chemical substance; that law of attraction and repulsion—the Parallelogram of Force—that holds the planets in their orbits. Divinity seems to have taken man into council and offered him, not only the Kingdom of Nature, but ...

... the kind of proof demanded by science. If the independence of all the possible distances between the atoms of a molecule is absolutely required by theoretical chemical research, then science is really compelled, in dealing with molecules of more than four atoms, to make use of the idea of a space ...

... not the right comparison. Consider it mud, invisible, impalpable, but heavy as mud. Nay, it goes beyond that. Consider every molecule of air to be a mudbank in itself. Then try to imagine the multitudinous impact of mudbanks. No; it is beyond me. Language may be adequate to express the ordinary conditions of life, but it cannot possibly express any of the conditions ...

... laws, and that they act on one another in accordance with these laws. Until therefore it is absolutely disproved, it must remain the simplest and most probable assumption that they are finally made of the same stuff, that the material molecule is in some kind of knot or ...

... been known to produce an off flavor in peaches, and it could very easily make an off flavor in pecans. In tests before this on Meadow spittle bugs on crops which might be used for food they did not use BHC, which would be cheaper. There are four or five different forms of the molecule that are important in making that and this gamma is the most important. We used a pound of this 25% gamma lindane and that apparently was the most successful. I didn't get this idea out of a clear sky. I talked to Dr. G. C. Decker and read one or two articles showing where ...

... sand, which preserves the impressions left by the waves. This dazzling carpet was a real mirror, throwing back the sun's rays with startling intensity. The outcome: an immense vista of reflections that penetrated every liquid molecule. Will anyone believe me if I assert that at this thirty-foot depth, I could see as ...

... only one like that. We are all in a muddle over there now and all through your science. Once there used to be atoms, five senses, four elements, and then everything hung together somehow. There were atoms in the ancient world even, but since we've learned that you've discovered the chemical molecule and protoplasm and the devil knows what, we had to lower our crest. There's a regular muddle, and, above all, superstition, scandal; there's as much scandal among us as among you, you know; a little more in fact, and spying, indeed, for we have our secret police ...

... composition of all food and all excrete being determined, and all heat that is given off being measured. Favorable conditions are thus established for an exact study of many problems of nutrition. The difficulties increase when we attempt to trace the successive steps in the corporeal pathway of molecule and atom. Yet these secrets of the vital process are also gradually being revealed. When we remember that it is in this very field of nutrition that there exist great popular ignorance and a special proneness to fad and prejudice, we realize ...

... if I may venture to so speak, the type, the organic molecule, of society. In the family, as M. de Bonald has very well observed, there exists but one moral being, one mind, one soul, I had almost said, with the Bible, one flesh. The family is the type and the cradle of monarchy and the patriciate: ...

... of starch by diastase, and even if not strictly correct it has, at any rate, proved itself to be a practical working hypothesis, by which the mashing and fermenting operations may be regulated and controlled. According to Brown and Morris, the starch molecule consists of five amylin groups, each of which corresponds to the molecular formula (C{12}H{20}O{10}){20}. Four of these amylin radicles are grouped centrally ...

... conception in its mystery—not only governs and controls the movements of all the mighty masses of matter rolling in space, but transmits its influence—not successively, but instantly and without diminution—to the smallest conceivable molecule on the outlying boundaries of the universe. In the same calm and comprehensive spirit, if it be possible for us to reach it, let us look upon this mysterious force called "life," not to show that it is simply a "correlate" of this or that motion (a thing utterly impossible of demonstration, ...

... dissolved in water cannot be said even yet to be fully settled, and, although there can be no doubt that solution is, in many cases, attended by chemical processes, still we possess as yet no means of deciding, with certainty, how many molecules of water have bound themselves to a single molecule of the dissolved substance (solute). On the other hand, we possess exact methods of testing whether gases or solutes in dilute solution react one with another and of determining the equilibrium state which is attained. For if one solute react with another on adding the latter to its solution, then ...

... by no means all that it gives to its possessor. He sees not only the inside as well as the outside of every object, but also its astral counterpart. Every atom and molecule of physical matter has its corresponding astral atoms and molecules, and the mass which is built up out of these is clearly visible to our clairvoyant. Usually the astral of any object projects somewhat beyond the physical part of it, and thus metals, stones and other ...

... complicated, each carbon atom having the power of linking itself with others to an extraordinary extent, so that it is no exceptional thing to find a substance which contains twenty or thirty atoms of carbon as well as other elements linked together in its molecule in a perfectly definite way, the molecule being still classifiable as that of a definite chemical compound. But there are also some non-elementary bodies which, although they are chemically complete and satisfied, retain a considerable vestige of power to link their molecules together ...

... machine-gun snap of popping popcorn, the clink and jingle of falling coins, and the yelps, bellows, howls, roars, snarls, grunts, bleats, moos, purrs, cackles, quacks, chirps, buzzes, and hisses of a myriad of animals, that each molecule would have thought that it was being shoved in a hundred thousand different directions at once if it had had a mind to ...

... and intelligence, acting in and through every atom, molecule and cell in the human body, which is the true healer, the vis medicatrix nature, which always endeavors to repair, to heal and to restore the perfect type. All that the physician can do is to remove obstructions and to establish normal conditions within and around the patient, so ...

... bromine will combine with one of hydrogen; one of oxygen with two of hydrogen; one of nitrogen with three of hydrogen; one of silicon with four of hydrogen, etc. They marry without thought of divorce. A group of atoms married by affinity is called a molecule. Two atoms of hydrogen joined to one of oxygen make water. They are like three marbles laid near together on the ground, not close together; for we well know that water does not fill all the space it occupies. We can put eight or ten similar bulks of other substances into a glass of water ...

... a few," I said. "They feel sure I can operate directly on the molecular chain in genes. This means we can alter heredity to suit ourselves. Next, why not rearrange the DNA molecule in a cancer? If you can change the genes in one cell, you can change them in another. Knock out the ability of cancerous cells to reproduce their own kind and the cancer disappears. A silly one: Maragon says I can be a one-man catalytic cracking station. Pipe a liquid through a tube within my TK ...

... elderly man came to me to show me how the universe was created. There was one molecule, which by vibration became—Heaven knows how!—the Sun. Further vibration produced Mercury, and so on. I suspect the nebular hypothesis had got into the poor man's head by reading, in some singular ...

... on between ethers and molecules is shown by the radiation of heat by all bodies. When the molecules are combined into a mass, this interaction ceases, so that the lightest objects fly through the ether without resistance. Why is this? Why does ether act on the molecule and not the mass? When we can produce the latter, and when the mutual action can be controlled, then may gravitation be overcome and then may men build, not merely airships, but ships which shall fly above the air, and transport their ...

... inconceivably minute particle revolves round the centre of the atom in its own orbit. On its own scale it is complete in itself, and by co-operation with thousands of others forms the atom. The atom again is a complete whole, but it must combine with other atoms to form a molecule, and so on. But if the atom be imperfect as an atom, how could it combine ...

... presents unfoldment, not accretion; it manifests no material growth from molecule to mind, but an impartation of the divine Mind to man 68:30 and the universe. Proportionately as human generation ceases, the unbroken links of eternal, har- monious being will be spiritually discerned; and man, 69:1 not of the earth earthly but coexistent with God, ...

... isn't like anything else in the known Galaxy. The molecules are huge; they can be seen with an ordinary optical microscope, and a microscopically visible molecule is a curious-looking object, to say the least. They use the stuff to treat fabric for protective garments. It isn't anything like collapsium, of course, but a suit of waxed coveralls weighing only a couple ...
