"Molecule" Quotes from Famous Books



... thing of which I am sure is, that the distinction between the organic and inorganic is arbitrary; that it is more coherent with our other ideas, and therefore more acceptable, to start with every molecule as a living thing, and then deduce death as the breaking up of an association or corporation, than to start with inanimate molecules and smuggle life into them; and that, therefore, what we call the inorganic world must be regarded as up to a certain point living, ...

... toe caps; six years which had not worn or chilled him, because, as he would have cheerfully admitted, he had recognised the facts and lowered his personal hopes of achievement—lowered them with a heroism which took account of himself as no more than a spiritual molecule rightly inspired and moving to the great future, already shining behind coming aeons, of the universal Kingdom. Indeed, his humility was scientific; he made his deductions from the granular nature of all change, moral and material. He never ...

... admit the cardinal, the nine parts of self-esteem in Gringoire, swollen and expanded by the breath of popular admiration, were in a state of prodigious augmentation, beneath which disappeared, as though stifled, that imperceptible molecule of which we have just remarked upon in the constitution of poets; a precious ingredient, by the way, a ballast of reality and humanity, without which they would not touch the earth. Gringoire enjoyed seeing, feeling, fingering, so to speak an entire assembly (of knaves, it is true, ...

... in its experimental application, is usually considered the most cogent sort of proof: yet when can the two sequent instances, before and after the introduction of a certain agent, be said to differ in nothing else? Are not earth and stars always changing position; is not every molecule in the room and apparatus always oscillating? It is true that our senses are now aided by elaborate instruments; but the construction of these depends on scientific theories, which again depend ...

... but is in the deepest sense a Divine effluence."[184] Yet he seems to get on without any very necessary reliance upon such an intervention, since the development from the atom to the civilized man is "a continuous process," and throughout the whole course from molecule to thought and moral and social law, "there are no lines of demarcation." He leaves it for the believer in theistic evolution to show when and where and how the ...

... marked allegro non assai (quick, but not too quick). In spirit it is noble, forceful, yet tender and extremely musical. The opening melody is itself made up thematically out of the first little molecule of two tones, or out of the first four tones, if you please. This is carried through sixteen measures in order to bring it to completion; it is immediately resumed with an added element of rhythmic motion and varieties of harmony, and ...

... compound must have at least two units in it. He suggested the name molecule for the least particle of a compound which can exist, retaining the name atom for the smallest particle of an element. In accordance with this distinction, we may define the atom and the molecule as follows: An atom is the smallest particle of an element which can exist. A molecule is the smallest particle of a compound which can exist. It will be shown in a subsequent chapter that sometimes two or more atoms of the same element unite with each other to form molecules of the element. While ...

... Love has been taken away from the poets, and has been brought within the domain of true science. It may prove to be one of the great cosmic elementary forces. When the atom of hydrogen draws the atom of chlorine towards it to form the perfected molecule of hydrochloric acid, the force which it exerts may be intrinsically similar to that which draws me to you. Attraction and repulsion appear to be the primary forces. This ...

... my brother, and we stand face to face with the imperishable truth of our being—the truth which makes us free, the truth which must ultimately prevail, by virtue of its own inherent Divinity; and we realize Man as he really is, not as he outwardly seems to be. We view him as a molecule, composed of a congregation of separate atoms, all of them held in their places by the centripetal force of the central human atom of life. And yet, small as he is, small as his kingdom is, compared with the mighty creation of which he is a part, he possesses all the inherent qualities ...

... of romance pledged to a flesh-and-blood abduction. The most fascinating female is apt to be encumbered with luggage and scruples: to take up a good deal of room in the present and overlap inconveniently into the future; whereas an idea can accommodate itself to a single molecule of the brain or expand to the circumference of the horizon. The Professor's companion had to the utmost this quality of adaptability. As the express train whirled him away from the somewhat inelastic circle of Mrs. Linyard's affections, his idea seemed to be sitting ...

... Woman on a Job; she thought in terms of money and offices; yet she was one with all the men and women, young and old, who were creating a new age. She was nothing in herself, yet as the molecule of water belongs to the ocean, so Una Golden humbly belonged to the leaven who, however confusedly, were beginning to demand, "Why, since we have machinery, science, courage, need we go on tolerating war and poverty and caste and uncouthness, ...

... is holy, which temple ye are.' He commands them to glorify God in their body as well as in their spirit; for 'know ye not,' says he, 'that your body is the temple of the Holy Ghost? What sort of a 'temple of the Holy Ghost' is he, every atom and molecule of whose physical system is saturated and stenched with the vile fetor of tobacco; whose every vesicle is distended by its foul gases; whose brain and marrow are begrimed and blackened with its sooty vapors and effluxions; all whose pores jet forth its malignant stream like so ...

... its atom compared with the weight of an atom of hydrogen. The atom of sulphur, for instance, is 32 times as heavy as the atom of hydrogen, and the atomic weight of sulphur is 32. The molecular weight is the sum of the atomic weights of the group. The molecule of pyrites contains two atoms of sulphur and one of iron: on referring to the table of atomic weights it will be seen that the atomic weights are—sulphur 32, and iron 56. The molecular weight, therefore, is 323256—that is, 120. The meaning ...

... forces. A dynamic theory, assigning attractive force to opposing bodies in proportion to the law of mass, takes for granted that the forces of nature capture man. The sum of force attracts; the feeble atom or molecule called man is attracted; he suffers education or growth; he is the sum of the forces that attract him; his body and his thought are alike their product; the movement of the forces controls the progress of his mind, since he can know nothing but the motions which impinge on his senses, whose ...

... physiologist, who knows that every individual being is so evolved—who knows, further, that in their earliest condition the germs of all plants and animals whatever are so similar, "that there is no appreciable distinction amongst them, which would enable it to be determined whether a particular molecule is the germ of a Conferva or of an Oak, of a Zoophyte or of a Man;"[1]—for him to make a difficulty of the matter is inexcusable. Surely if a single cell may, when subjected to certain influences, become ...

... creature is the lover and the Creator the Beloved: worldly existence is Disunion, parting, severance; and the life to come is Reunion. The basis of the idea is the human soul being a divin particula aur, a disjoined molecule from the Great Spirit, imprisoned in a jail of flesh; and it is so far valuable that it has produced a grand and pathetic poetry; but Common Sense asks, Where is the proof? And Reason wants to know, ...

... designs are more or less radio-active—namely, changing into other elements, but some, like radium, polonium, &c., are active to an extraordinary extent. Each molecule or atom may be looked upon as an aperture, more or less open, through which we have flowing the equivalent of what may be called a leak from the Infinite, the changing of one element into another being represented by the change of shape or activity of that aperture. Countless ages ago these ...

... should see movements of the ice molecules become gradually more rapid, just as the iron molecules did when the iron was warmed. Then, as they moved faster and faster, they would begin to bump into each other and go around every which way, each molecule bumping first into one neighbor, then into another, and bouncing back in a new direction after each collision. This is what causes the ice to melt. When its molecules no longer go back and forth in the same path all the time, the ice no longer keeps its shape, and ...

... the first few pages of the book of the heavens—the last pages of which no man shall ever read. For aeons upon aeons of time, worlds and suns, and systems of worlds and suns, revolved through the infinity of space, before man made his appearance on the tiny molecule of matter we call the earth, and for aeons upon aeons, for eternity upon eternity, worlds and suns shall continue to roll and revolve after the last vestige of man shall have disappeared, nay after the atoms of earth ...

... universe consists of matter, matter diffused and dead, [Footnote: I have tried hard to grasp the idea of a living molecule, but in vain. The idea of matter feeling without any senses seems to me unintelligible and self-contradictory. To accept or reject this idea one must first understand it, and I confess that so far I have not succeeded.] matter which has none of the cohesion, ...

... possibilities. But now, I find that it has a direct connection with the collapsed-matter problem. When the electron loses its negative charge and reverts to a neutrino, there is a definite accretion of interatomic binding-force, and the molecule, or the crystalline lattice or whatever tends to contract, and when the neutrino becomes a photon, the nucleus of the ...

... For while the laws of the spirit are ever the same in essence, the character of their manifestation varies with time and place, just as in Nature the same force appears in the firmament as gravitation when it binds star unto star, as attraction when it binds in the molecule atom unto atom, and in man as love when it binds heart unto heart. The phenomena therefore, natural to all literature, we shall also find here, but modified by the ...

... immense Milky Way which on clear nights we behold stretching across the heavens, this vast encircling ring in which our planetary system is itself but a molecule, is in its turn but a cell in the Universe, in the Body of God. All the cells of our body combine and co-operate in maintaining and kindling by their activity our consciousness, our soul; and if the consciousness or the souls of all these cells entered completely into our consciousness, into ...

... scientific study. Now, the entire science of chemistry in all its branches is built upon the axiom that molecules are absolutely unalterable and that molecules of the same kind are always absolutely identical. A molecule of water is always and invariably composed of two atoms of hydrogen and one of oxygen. A molecule of sulphuric acid invariably contains two atoms of hydrogen, one of sulphur, and four of oxygen. A molecule of potassium chlorate is always composed of just one ...

... repulsive envelopes, we may explain all the general properties of matter; and, by more and more complex arrangements, even the special chemical, electrical, and magnetic properties of special forms of matter.[I] Each chemical element will thus consist of a molecule formed of simple atoms, (or as Mr. Bayma terms them to avoid confusion, "material elements") in greater or less number and of more or less complex arrangement; which molecule is in stable equilibrium, but liable to be changed in form by the attractive or repulsive influences of differently ...
