Chemical Quotes

Your remarks upon chemical notation with the variety of systems which have arisen, andc., andc., had almost stirred me up to regret publicly that such hindrances to the progress of science should exist. I cannot help thinking it a most unfortunate thing that men who as experimentalists and philosophers are the most fitted to advance the general cause of science and knowledge should by promulgation of their own theoretical views under the form of nomenclature, notation, or scale, actually retard its progress Picture Quote #1

The first entirely vital action, so termed because it is not effected outside the influence of life, consists in the creation of the glycogenic material in the living hepatic tissue. The second entirely chemical action, which can be effected outside the influence of life, consists in the transformation of the glycogenic material into sugar by means of a ferment Picture Quote #1

Every chemical substance, whether natural or artificial, falls into one of two major categories, according to the spatial characteristic of its form. The distinction is between those substances that have a plane of symmetry and those that do not. The former belong to the mineral, the latter to the living world Picture Quote #1

Today, when we look at a brain, we see an intricate network of billions of neurons in constant, crackling communication, a chemical labyrinth that senses the world outside and within, produces love and sorrow, keeps our hearts beating and lungs breathing, composes our thoughts, and constructs our consciousness Picture Quote #1

I will now direct the attention of scientists to a previously unnoticed cause which brings about the metamorphosis and decomposition phenomena which are usually called decay, putrefaction, rotting, fermentation and moldering. This cause is the ability possessed by a body engaged in decomposition or combination, i.e. in chemical action, to give rise in a body in contact with it the same ability to undergo the same change which it experiences itself Picture Quote #1

We may lay it down as an incontestible axiom, that, in all the operations of art and nature, nothing is created; an equal quantity of matter exists both before and after the experiment; the quality and quantity of the elements remain precisely the same; and nothing takes place beyond changes and modifications in the combination of these elements. Upon this principle the whole art of performing chemical experiments depends: We must always suppose an exact equality between the elements of the body examined and those of the products of its analysis Picture Quote #1

A cell of a higher organism contains a thousand different substances, arranged in a complex system. This great organized system was not discovered by chemical or physical methods; they are inadequate to its refinement and delicacy and complexity Picture Quote #1

All the more recent work on alkaptonuria has... strengthened the belief that the homogentisic acid excreted is derived from tyrosin, but why alkaptonuric individuals pass the benzene ring of their tyrosin unbroken and how and where the peculiar chemical change from tyrosin to homogentisic acid is brought about, remain unsolved problems Picture Quote #1

My main thesis will be that in the study of the intermediate processes of metabolism we have to deal not with complex substances which elude ordinary chemical methods, but with the simple substances undergoing comprehensible reactions... I intend also to emphasise the fact that it is not alone with the separation and identification of products from the animal that our present studies deal; but with their reactions in the body; with the dynamic side of biochemical phenomena Picture Quote #1

The blood corpuscles take up the atmospheric oxygen in the lungs, and the vital chemical process accordingly depends essentially on the combination of oxygen absorbed by blood corpuscles with the combustible constituents of the blood to form carbonic acid and water Picture Quote #1

The mechanist is intimately convinced that a precise knowledge of the chemical constitution, structure, and properties of the various organelles of a cell will solve biological problems. This will come in a few centuries. For the time being, the biologist has to face such concepts as orienting forces or morphogenetic fields. Owing to the scarcity of chemical data and to the complexity of life, and despite the progresses of biochemistry, the biologist is still threatened with vertigo Picture Quote #1

Life itself is but the expression of a sum of phenomena, each of which follows the ordinary physical and chemical laws Picture Quote #1

The cell, this elementary keystone of living nature, is far from being a peculiar chemical giant molecule or even a living protein and as such is not likely to fall prey to the field of an advanced chemistry. The cell is itself an organism, constituted of many small units of life Picture Quote #1

Unless the chemist learns the language of mathematics, he will become a provincial and the higher branches of chemical work, that require reason as well as skill, will gradually pass out of his hands Picture Quote #1

The fact is the physical chemists never use their eyes and are most lamentably lacking in chemical culture. It is essential to cast out from our midst, root and branch, this physical element and return to our laboratories Picture Quote #1

The sensitive plate, the gas which is ionised, the fluorescent screen, are in reality receivers, into another kind of energy, chemical energy, ionic energy... luminous energy Picture Quote #1

The world of chemical reactions is like a stage, on which scene after scene is ceaselessly played. The actors on it are the elements Picture Quote #1

There is a joy in the actual taste of vanilla ice cream that does not come from knowing the chemical formula of vanilla. There is a joy, an inherent aliveness in the body that you can experience if you pay attention to your body. But if you live up in your head, in your words all the time, you don’t notice it Picture Quote #1

At our most elemental, we are not a chemical reaction, but an energetic charge. Human beings and all living things are a coalescence of energy in a field of energy connected to every other thing in the world. This pulsating energy field is the central engine of our being and our consciousness, the alpha and the omega of our existence Picture Quote #1

The cold view to take of our future is that we are therefore headed for extinction in a universe of impersonal chemical, physical, and biological laws. A more productive, certainly more engaging view, is that we have the intelligence to grasp what is happening, the composure not to be intimidated by its complexity, and the courage to take steps that may bear no fruit in our lifetimes Picture Quote #1

We may, I believe, anticipate that the chemist of the future who is interested in the structure of proteins, nucleic acids, polysaccharides, and other complex substances with high molecular weight will come to rely upon a new structural chemistry, involving precise geometrical relationships among the atoms in the molecules and the rigorous application of the new structural principles, and that great progress will be made, through this technique, in the attack, by chemical methods, on the problems of biology and medicine Picture Quote #1

No new creation or destruction of matter is within the reach of chemical agency. We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence, as to create or destroy a particle of hydrogen Picture Quote #1

Filmmakers don’t work for posterity. We create with celluloid and chemical pigments that don’t last very long. They fade away. In 200 years there will be nothing left of our work but dust Picture Quote #1

The more details we learn about the chemical basis of life and the intricacy of the genetic code, the more unbelievable the standard historical account becomes Picture Quote #1

I look to everyday magic in art to remember how to live: how to estrange and vivify ordinary objects and beings. So little, really, is ordinary, but to remember this I need the brain chemical of painting and film and reading I had a thrummy doomed oracular feeling when I wrote blackened baby teeth into my little blind boy story: I saw teeth and in an instant they were becoming something else. They were buckshot. They were food. They were tiny flightless corvids Picture Quote #1

Land degradation did not start with chemical agriculture. But chemical agriculture offered new tools for annihilation Picture Quote #1

I swear, there is no chemical drug out there that can reproduce the feelings you have of achieving your goals Picture Quote #1

Where did feelings go when they disappeared? Did they leave a chemical trace somewhere in our minds, so that if we could look inside ourselves we would see via the patterns of neurons some of the important things that had happened to us in our lifetimes? Picture Quote #1

You walk into a room, see a woman, and something happens. It’s chemical. What are you going to do about it? Picture Quote #1

Someone needs to explain to me why wanting clean drinking water makes you an activist, and why proposing to destroy water with chemical warfare doesnt make a corporation a terrorist Picture Quote #1
