"Atomic theory" Quotes from Famous Books
 ... series of the most different theories rapidly succeed each other, none of which can be positively proved, though at least one of them is taught by every professor of chemistry. But what is worst of all, the common basis of all the most dissimilar chemical theories, viz., the atomic theory, is as unproved and unprovable as any hypothesis can be. No chemist has ever seen an atom, but he nevertheless considers the mechanism of atoms as the highest term of his science, he nevertheless describes and constructs the connection of atoms ...

... found, the laws would be no longer true, and the hypothesis of Dalton would cease to possess value. When an hypothesis has been tested in every way in which experiment can test it, and is still found to be in harmony with the facts in the case, it is termed a theory. We now speak of the atomic theory rather than of ...

... those quantities of them which contain equal quantities of electricity, or have naturally equal electric powers, it being the electricity which determines the equivalent number, because it determines the combining force. Or, if we adopt the atomic theory or phraseology, then the atoms of bodies which are equivalent to each other in their ordinary chemical action have equal quantities of electricity naturally associated with them. I cannot refrain from recalling here the beautiful idea put forth, I believe, ...

... little, if anything; but from a theoretical point of view, the tone of his writings is singularly modern. His work was mostly done before Dalton had announced the atomic theory; and yet Smithson saw clearly that a law of definite proportions must exist, although he did not attempt to account for it. His ability as a reasoner is best shown in his paper on the Kirkdale Bone Cave, which Penn had sought to interpret by reference to the Noachian Deluge. A clearer and ...

... each absolutely similar to the other; these formed the essential unity which could be grasped only by the reason, but by their various combinations and arrangements they brought about the apparent multiplicity of objects which the senses perceived. Such was the foundation of the atomic theory of Democritus. He conceived the atom as a centre of force, and not as a particle having weight and material qualities. As, however, his hypothesis was purely a metaphysical one, it did not lead to any of the discoveries which have followed on the establishment of the modern scientific theory, ...

... throughout the stellar universe with timeless simultaneity. It is in entire keeping with everything else in the workings of God, as demonstrated by science, on every hand, both in nature and history. The atomic theory and the nebular hypothesis, the chemical crucible and the mathematical calculus, the microscope and the telescope discover to our senses and our reason, wherever we look, facts as mysterious to the understanding, and as baffling to the imagination as any of the foregoing implications; showing ...
