Quotes & Sayings About Chemical Compounds

In the first quarter of the nineteenth century the experimental proof for the interdependence of the composition and properties of chemical compounds resulted in the theory that they are mutually related, so that like composition governs like properties, and conversely. — Wilhelm, Ostwald

The world always thinks that the destruction of a physical vessel is victory," he said quietly. "But the Savior was more than merely cells and tissue and chemical compounds - and Fidelacchius is more than wood and steel. — Jim Butcher

As soon as we can wrest from Nature the secret of the internal structure of the compounds produced by her, chemical science can then even surpass Nature by producing compounds as variations of the natural ones, which the living cell is unable to construct. — Otto Wallach

Chemical compounds of carbon can exist in an infinite variety of compositions, forms and sizes. The naturally occurring organic substances are the basis of all life on Earth, and their science at the molecular level defines a fundamental language of that life. — Elias James Corey

There is no sharp boundary line separating the reactions of the immune bodies from chemical processes between crystalloids, just as in nature there exists every stage between crystalloid and colloid. The nearer the colloid particle approximates to the normal electrolyte, the nearer its compounds must obviously come to conforming to the law of simple stoichiometric proportions, and the compounds themselves to simple chemical compounds. At this point, it should be recalled that Arrhenius has shown that the quantitative relationship between toxin and antitoxin is very similar to that between acid and base. — Karl Landsteiner

Moreover, the abundance of chemical compounds and their importance in daily life hindered the chemist from investigating the question, in what does the individuality of the atoms of different elements consist. — Johannes Stark

An example of such emergent phenomena is the origin of life from non-living chemical compounds in the oldest, lifeless oceans of the earth. Here, aided by the radiation energy received from the sun, countless chemical materials were synthesized and accumulated in such a way that they constituted, as it were, a primeval "soup." In this primeval soup, by infinite variations of lifeless growth and decay of substances during some billions of years, the way of life was ultimately reached, with its metabolism characterized by selective assimilation and dissimilation as end stations of a sluiced and canalized flow of free chemical energy. — R.W. Van Bemmelen

Trees don't rely exclusively on dispersal in the air, for if they did, some neighbors would not get wind of the danger. Dr. Suzanne Simard of the University of British Columbia in Vancouver has discovered that they also warn each other using chemical signals sent through the fungal networks around their root tips, which operate no matter what the weather. Surprisingly, news bulletins are sent via the roots not only by means of chemical compounds but also by means of electrical impulses that travel at the speed of a third of an inch per second. In comparison with our bodies, it is, admittedly, extremely slow. However there are species in the animal kingdom, such as jellyfish and worms, whose nervous systems conduct impulses at similar speed. Once the latest news has been broadcast, all oaks int he area promptly pump tannins through their veins. — Peter Wohlleben

Today these four crops account for two thirds of the calories we eat. When you consider that humankind has historically consumed some eighty thousand edible species, and that three thousand of these have been in widespread use, this represents a radical simplification of the human diet. Why should this concern us? Because humans are omnivores, requiring somewhere between fifty and a hundred different chemical compounds and elements in order to be healthy. — Michael Pollan

It was common, back then," said Vikram, rolling his tea glass between his palms. "Living books. Alchemists were always trying to create them. There was the Quran, which shattered language and put it back together again in a way no one had been able to replicate, using words whose meanings evolved over time without the alteration of a single dot or brushstroke. As above, so below, the alchemists reasoned-they thought they could reverse-engineer the living word using chemical compounds. If they could create a book that was literally alive, perhaps it would also produce knowledge that transcended time."
"That's pretty blasphemous," said the convert.
"Oh, very. Heretics, my dear. They made the hashisheen look orthodox. — G. Willow Wilson

The chemical compounds are comparable to a system of planets in that the atoms are held together by chemical affinity. They may be more or less numerous, simple or complex in composition, and in the constitution of the materials, they play the same role as Mars and Venus do in our planetary system, or the compound members such as our earth with its moon, or Jupiter with its satellites ... If in such a system a particle is replaced by one of different character, the equilibrium can persist, and then the new compound will exhibit properties similar to those shown by the original substance. — Jean-Baptiste Dumas
