"Chemical analysis" Quotes from Famous Books
 ... accidental contact of two heterogeneous metals, his contemporaries could never have anticipated that the action of the voltaic pile would discover to us, in the alkalies, metals of a silvery luster, so light as to swim on water, and eminently inflammable; or that it would become a powerful instrument of chemical analysis, and at the same time a thermoscope and a magnet. When Hygens first observed, in 1678, the phenomenon of the polarization of light, exhibited in the difference between the two rays into which a pencil of light divides itself in passing through a ...

... broke into several pieces. The inhabitants collected the still warm fragments, and judging by these, the stones must have weighed full fifteen pounds each. They were grey inside, and were externally surrounded by a black burnt crust. On a chemical analysis, they appeared to resemble the meteoric stones which ...

... with other souls. These discourses were given at regular intervals, and much of our time was spent in discussing together or working out in solitude the details of psychological problems, which we did with the exactness of chemical analysis. ...

... that the soil contains within itself some available plant food. We can determine by chemical analysis the exact amounts of the various plant foods—nitrogen, phosphoric acid, potash, etc.—which a crop of any vegetable will remove from the soil. The idea in scientific chemical manuring is to add to the available plant foods already in the soil just enough more ...

... uninterruptedly, but insensibly, broadening amelioration which we see peacefully accomplishing itself in the course of history, if it is not this same scientific knowledge? And, this being so, science must have its way without restraint; for science there is nothing fixed and definite, to which its process of chemical analysis may not be applied, nothing sacred, no noli me tangere. Without free scientific inquiry, therefore, there is no outcome but stagnation, decline and barbarism. And, while free scientific inquiry is the perennial fountain-head of all progress in human affairs, this inquiry and its ...

... discussed, but the general verdict of the great body of consumers is that the patent or new process flour is better in every way for bread making purposes, being clearer, whiter, more evenly granulated, and possessing more strength. Careful chemical analysis has confirmed this. As between winter and spring wheat flours made by the new process and gradual reduction systems, it maybe remarked that the former contain more starch and are whiter in color, while the latter, having more gluten, excel in strength. In milling all varieties ...

... 'Peau de chagrin,' but still among its author's best novels, should be placed 'La Recherche de l'absolu,' which, as its title implies, describes the efforts of a chemist to "prove by chemical analysis the unity of composition of matter." In the pursuit of his philosophic will-o'-the-wisp, Balthazar Claes loses his fortune and sacrifices his noble wife and children. His madness serves, however, to bring into relief the splendid qualities of these latter; and ...

... investigation. Spectrum analysis may be shortly described as a mode of distinguishing the various species of matter by the kind of light proceeding from each. This definition at once explains how it is that, unlike every other system of chemical analysis, it has proved available in astronomy. Light, so far as quality is concerned, ignores distance. No intrinsic change, that we yet know of, is produced in it by a journey from the farthest bounds of the visible universe; so that, provided only that in quantity it remain sufficient ...
