Chemistry Quotes

If the results of the present study on the chemical nature of the transforming principle are confirmed, then nucleic acids must be regarded as possessing biological specificity the chemical basis of which is as yet undetermined.

[The] structural theory is of extreme simplicity. It assumes that the molecule is held together by links between one atom and the next: that every kind of atom can form a definite small number of such links: that these can be single, double or triple: that the groups may take up any position possible by rotation round the line of a single but not round that of a double link: finally that with all the elements of the first short period [of the periodic table], and with many others as well, the angles between the valencies are approximately those formed by joining the centre of a regular tetrahedron to its angular points. No assumption whatever is made as to the mechanism of the linkage. Through the whole development of organic chemistry this theory has always proved capable of providing a different structure for every different compound that can be isolated. Among the hundreds of thousands of known substances, there are never more isomeric forms than the theory permits.

Pussy is everywhere. Dick is everywhere. Chemistry isn't.

Together, we form a necessary paradox; not a senseless contradiction.

It was the first time! Just because there weren’t fireworks the first time doesn’t mean there will never be fireworks. We’re human; we’re adults; we teach each other; we communicate; fireworks don’t just go off, wham-bang; fireworks evolve!’Awestruck by the utter, asinine nonsense of this metaphor, everyone is still. Into the stillness, the ample woman drops the word ‘Wrong.’ Then she says it again. ‘Wrong…I’m talking about science…Pheromones.’ The woman turns to Cornelia. ‘The chemicals in his body call out. The chemicals in your body answer. It either happens or it doesn’t.’On top of being dumb, Cornelia is dumbfounded.

All that happens in the human brain is but the result of electro-chemical reactions. Be it of love, hate, of pleasure, of suffering, of imagination, or all other states of mind, sentiment or sickness; the process depends in every case on the chemical reactions produced in the interior of the brain, and the resulting electrical impulses or messages, be they visual, auditory, based on memory, or an interpretation of new events based on elements that one has in the memory.

You know, rust is just oxidation. The same chemical process as fire. Oxygen interacts with steel, electrons drift from one element to the other. So really, rust is a slow fire. Isn't that weird? Water causes something to burn.

THE MAXIMS OF MEDICINE Before you examine the body of a patient,Be patient to learn his story.For once you learn his story,You will also come to knowHis body.Before you diagnose any sickness,Make sure there is no sickness in the mind or heart.For the emotions in a man’s moon or sun,Can point to the sickness inAny one of his other parts.Before you treat a man with a condition,Know that not all cures can heal all people.For the chemistry that works on one patient,May not work for the next,Because even medicine has its ownConditions.Before asserting a prognosis on any patient,Always be objective and never subjective.For telling a man that he will win the treasure of life,But then later discovering that he will lose,Will harm him more than by telling himThat he may lose,But then he wins.THE MAXIMS OF MEDICINE by Suzy Kassem

In chemistry, our theories are crutches; to show that they are valid, they must be used to walk... A theory established with the help of twenty facts must explain thirty, and lead to the discovery of ten more.

Undeniable chemistry and horrific timing. They love each other.

Before you treat a man with a condition, know that not all cures can heal all people. For the chemistry that works on one patient may not work for the next, because even medicine has its own conditions.

This theory [the oxygen theory] is not as I have heard it described, that of the French chemists, it is mine (elle est la mienne); it is a property which I claim from my contemporaries and from posterity.

Dissection ... teaches us that the body of man is made up of certain kinds of material, so differing from each other in optical and other physical characters and so built up together as to give the body certain structural features. Chemical examination further teaches us that these kinds of material are composed of various chemical substances, a large number of which have this characteristic that they possess a considerable amount of potential energy capable of being set free, rendered actual, by oxidation or some other chemical change. Thus the body as a whole may, from a chemical point of view, be considered as a mass of various chemical substances, representing altogether a considerable capital of potential energy.

I studied calculus for the first time, which to me was an amazingly empowering experience which I could really see how you could understand all sorts of things, and I decided that chemistry and biology just had too much memory for me to be interested. Physics was very easy.

I looked for it [heavy hydrogen, deuterium] because I thought it should exist. I didn't know it would have industrial applications or be the basic for the most powerful weapon ever known [the nuclear bomb] ... I thought maybe my discovery might have the practical value of, say, neon in neon s

Planck...and Bohr...have invented systems containing electrons of which the motion produces no effect upon external charges...[N]ot only [is this] inconsistent with the accepted laws of electromagnetism, but I may add, is logically objectionable, for that state of motion which produces no physical effect whatsoever may better be called a state of rest.

You were sizzling, like sausages in a frying pan.

On the stage Tristen bent over the piano, his fingers swift and sure, his blond hair gleaming under the spotlight. I glanced around at the audience, watching their faces, gratified that they were as captivated as I was by the dark, thunderous song that Tristen conjured.

I might paraphrase Churchill and say: never have I received so much for so little.[Exemplifying humility, upon accepting the Nobel Prize in Chemistry.]

Those distinct substances, which concretes generally either afford, or are made up of, may, without very much inconvenience, be called the elements or principles of them.

Time is a strange phenomenon that understands the physics of our world, but never the chemistry of it

And I often dream of chemistry at night, dreams that conflate the past and the present, the grid of the periodic table transformed to the grid of Manhattan. […] Sometimes, too, I dream of the indecipherable language of tin (a confused memory, perhaps, of its plaintive “cry”). But my favorite dream is of going to the opera (I am Hafnium), sharing a box at the Met with the other heavy transition metals—my old and valued friends—Tantalum, Rhenium, Osmium, Iridium, Platinum, Gold, and Tungsten.

A DNA sequence for the genome of bacteriophage ΦX174 of approximately 5,375 nucleotides has been determined using the rapid and simple 'plus and minus' method. The sequence identifies many of the features responsible for the production of the proteins of the nine known genes of the organism, including initiation and termination sites for the proteins and RNAs. Two pairs of genes are coded by the same region of DNA using different reading frames.

Dr. Morris soon recognized that the difference between successful and unsuccessful marriages can often be traced to how well couples are able to "bond" during the courtship period. By bonding he referred to the process by which a man and woman become cemented together emotionally. It describes the chemistry that permits two previous strangers to become intensely valuable to one another. It helps them weather the storms of life and remain committed in sickness and health, for richer or poorer, for better or worse, forsaking all others until they are parted in death. It is a phenomenal experience that almost defies description.

I took a glass retort, capable of containing eight ounces of water, and distilled fuming spirit of nitre according to the usual method. In the beginning the acid passed over red, then it became colourless, and lastly again all red: no sooner did this happen, then I took away the receiver; and tied to the mouth of the retort a bladder emptied of air, which I had moistened in its inside with milk of lime lac calcis, (i.e. lime-water, containing more quicklime than water can dissolve) to prevent its being corroded by the acid. Then I continued the distillation, and the bladder gradually expanded. Here-upon I left every thing to cool, tied up the bladder, and took it off from the mouth of the retort.— I filled a ten-ounce glass with this air and put a small burning candle into it; when immediately the candle burnt with a large flame, of so vivid a light that it dazzled the eyes. I mixed one part of this air with three parts of air, wherein fire would not burn; and this mixture afforded air, in every respect familiar to the common sort. Since this air is absolutely necessary for the generation of fire, and makes about one-third of our common air, I shall henceforth, for shortness sake call it empyreal air, [literally fire-air] the air which is unserviceable for the fiery phenomenon, and which makes abut two-thirds of common air, I shall for the future call foul air [literally corrupted air].

The fundamental laws of the universe which correspond to the two fundamental theorems of the mechanical theory of heat.1. The energy of the universe is constant.2. The entropy of the universe tends to a maximum.

His attention felt more like an irrepressible gravitational pull than mere interest.

In the last four days I have got the (results) given by Tantalum, Chromium, Manganese, Iron , Nickel, Cobalt and Copper ... The chief result is that ... the result for any metal (is) quite easy to guess from the results for the others. This shews that the insides of all the atoms are very much alike, and from these results it will be possible to find out something of what the insides are made up of.

The human mind adjusts itself to a certain point of view, and those who have regarded nature from one angle, during a portion of their life, can adopt new ideas only with difficulty.

Chemistry has the same quickening and suggestive influence upon the algebraist as a visit to the Royal Academy, or the old masters may be supposed to have on a Browning or a Tennyson. Indeed it seems to me that an exact homology exists between painting and poetry on the one hand and modem chemistry and modem algebra on the other. In poetry and algebra we have the pure idea elaborated and expressed through the vehicle of language, in painting and chemistry the idea enveloped in matter, depending in part on manual processes and the resources of art for its due manifestation.

[Henry Cavendish] fixed the weight of the earth; he established the proportions of the constituents of the air; he occupied himself with the quantitative study of the laws of heat; and lastly, he demonstrated the nature of water and determined its volumetric composition. Earth, air, fire, and water—each and all came within the range of his observations.

What does despair mean to someone who interprets that emotion as a chemical reaction in the brain?

We need science education to produce scientists, but we need it equally to create literacy in the public. Man has a fundamental urge to comprehend the world about him, and science gives today the only world picture which we can consider as valid. It gives an understanding of the inside of the atom and of the whole universe, or the peculiar properties of the chemical substances and of the manner in which genes duplicate in biology. An educated layman can, of course, not contribute to science, but can enjoy and participate in many scientific discoveries which as constantly made. Such participation was quite common in the 19th century, but has unhappily declined. Literacy in science will enrich a person's life.

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.

The discovery of an interaction among the four hemes made it obvious that they must be touching, but in science what is obvious is not necessarily true. When the structure of hemoglobin was finally solved, the hemes were found to lie in isolated pockets on the surface of the subunits. Without contact between them how could one of them sense whether the others had combined with oxygen? And how could as heterogeneous a collection of chemical agents as protons, chloride ions, carbon dioxide, and diphosphoglycerate influence the oxygen equilibrium curve in a similar way? It did not seem plausible that any of them could bind directly to the hemes or that all of them could bind at any other common site, although there again it turned out we were wrong. To add to the mystery, none of these agents affected the oxygen equilibrium of myoglobin or of isolated subunits of hemoglobin. We now know that all the cooperative effects disappear if the hemoglobin molecule is merely split in half, but this vital clue was missed. Like Agatha Christie, Nature kept it to the last to make the story more exciting. There are two ways out of an impasse in science: to experiment or to think. By temperament, perhaps, I experimented, whereas Jacques Monod thought.

That the nobility of Man, acquired in a hundred centuries of trial and error, lay in making himself the conquerer of matter, and that I had enrolled in chemistry because I wanted to maintain faithful to that nobility. That conquering matter is to understand it, and understanding matter is necessary to understanding the universe and ourselves: and that therefore Mendeleev’s Periodic Table, which just during those weeks we were laboriously learning to unravel, was poetry, loftier and more solemn than all the poetry we had swallowed doen in liceo; and come to think of it, it even rhymed! …[T]he chemistry and physics on which we fed, besides being in themselves nourishments vital in themselves, were the antidotes to Fascism … because they were clear and distinct and verifiable at every step, and not a tissue of lies and emptiness like the radio and newspapers.

Everything, decided Francie after that first lecture, was vibrant with life and there was no death in chemistry. She was puzzled as to why learned people didn't adopt chemistry as a religion.

A woman or man of value doesn’t love you because of what he or she wants you to be or do for them. He or she loves you because your combined souls understand one another, complements each other, and make sense above any other person in this world. You each share a part of their soul's mirror and see each other’s light reflected in it clearly. You can easily speak from the heart and feel safe doing so. Both of you have been traveling a parallel road your entire life. Without each other's presence, you feel like an old friend or family member was lost. It bothers you, not because you have given it too much meaning, but because God did. This is the type of person you don't have to fight for because you can't get rid of them and your heart doesn't want them to leave anyways.

Everything feels right with her. I can’t explain it. The world just stops. Everything freezes. It’s me. It’s her. It’s just us. Everything else, every molecule, including the oxygen we breathe, is only secondary to the chemistry we create. When we watch a movie it’s more than images strung together in the form of mindless entertainment. It’s an experience. An experience we share together from making the popcorn to watching the film to talking about it for days after. Chemistry. What more can I say? You either have it or you don’t.

In the vestibule of the Manchester Town Hall are placed two life-sized marble statues facing each other. One of these is that of John Dalton ... the other that of James Prescott Joule. ... Thus the honour is done to Manchester's two greatest sons—to Dalton, the founder of modern Chemistry and of the atomic theory, and the laws of chemical-combining proportions; to Joule, the founder of modern physics and the discoverer of the Law of Conservation of Energy.One gave to the world the final proof ... that in every kind of chemical change no loss of matter occurs; the other proved that in all the varied modes of physical change, no loss of energy takes place.

On Titan the molecules that have been raining down like manna from heaven for the last 4 billion years might still be there largely unaltered deep-frozen awaiting the chemists from Earth

Any chemist reading this book can see, in some detail, how I have spent most of my mature life. They can become familiar with the quality of my mind and imagination. They can make judgements about my research abilities. They can tell how well I have documented my claims of experimental results. Any scientist can redo my experiments to see if they still work—and this has happened! I know of no other field in which contributions to world culture are so clearly on exhibit, so cumulative, and so subject to verification.

I always hoped for this spark of chemistry and compatibility, a flash of clarity to let me know that this was the guy, this was the time, so I should leg go and enjoy myself. But it never came. And by no small coincidence, neither did I.

My mother showed me that when tin or zinc was bent it uttered a special ‘cry’. ‘It’s due to deformation of the crystal structure,’ she said, forgetting that I was five, and could not understand her - and yet her words fascinated me, made me want to know more.

It has been demonstrated that a species of penicillium produces in culture a very powerful antibacterial substance which affects different bacteria in different degrees. Generally speaking it may be said that the least sensitive bacteria are the Gram-negative bacilli, and the most susceptible are the pyogenic cocci ... In addition to its possible use in the treatment of bacterial infections penicillin is certainly useful... for its power of inhibiting unwanted microbes in bacterial cultures so that penicillin insensitive bacteria can readily be isolated.

At my urgent request the Curie laboratory, in which radium was discovered a short time ago, was shown to me. The Curies themselves were away travelling. It was a cross between a stable and a potato-cellar, and, if I had not seen the worktable with the chemical apparatus, I would have thought it a practical joke.(Wilhelm Ostwald on seeing the Curie's laboratory facilities.)

A union of literary and scientific cultures – there was not the dissociation of sensibility that was so soon to come ... Davy himself was writing (and sometimes publishing) a good deal of poetry at the time; his notebooks mix details of chemical experiments, poems, and philosophical reflections all together; and these did not seem to exist in separate compartments in his mind.

Some of us have deeper feelings for one over another. It can’t be helped. It’s chemistry. It’s inherent. You can’t make yourself love someone you don’t and you can’t make yourself stop loving someone you do.

It were indeed to be wish'd that our art had been less ingenious, in contriving means destructive to mankind; we mean those instruments of war, which were unknown to the ancients, and have made such havoc among the moderns. But as men have always been bent on seeking each other's destruction by continual wars; and as force, when brought against us, can only be repelled by force; the chief support of war, must, after money, be now sought in chemistry.

Upon the whole, Chymistry is as yet but an opening science, closely connected with the useful and ornamental arts, and worthy the attention of the liberal mind. And it must always become more and more so: for though it is only of late, that it has been looked upon in that light, the great progress already made in Chymical knowledge, gives us a pleasant prospect of rich additions to it. The Science is now studied on solid and rational grounds. While our knowledge is imperfect, it is apt to run into error: but Experiment is the thread that will lead us out of the labyrinth.

O woman, thou art my imperfection!

My laboratory is interested in the related challenges of understanding the origin of life on the early earth, and constructing synthetic cellular life in the laboratory. Focusing on artificial life frees us to explore novel chemical systems, but what we learn from these systems helps us to understand possible pathways leading to the origin of life. Our basic design for a synthetic cell involves the encapsulation of a spontaneously replicating nucleic acid, which acts as the genetic material, within a spontaneously replicating membrane vesicle, which provides spatial localization. We are using chemical synthesis to make nucleic acids with modified nucleobases and sugar-phosphate backbones.

People used to recognize it as mood.Science has revealed it as cannabinoids.When you feel sad, just do long running.Then you will know that even mood can be governed.

The meeting of two personalities is like the contact of two chemical substances: if there is any reaction, both are transformed.

Our eyes met and our souls caught on fire.

During this time (at high school) I discovered the Public Library... It was here that I found a source of knowledge and the means to acquire it by reading, a habit of learning which I still follow to this day. I also became interested in chemistry and gradually accumulated enough test tubes and other glassware to do chemical experiments, using small quantities of chemicals purchased from a pharmacy supply house. I soon graduated to biochemistry and tried to discover what gave flowers their distinctive colours. I made the (to me) astounding discovery that the pigments I extracted changed their colours when I changed the pH of the solution.

We owe our liberation to chemistry," he went on. "For all perception is but a change in the concentration of hydrogen ions on the surface of the brain cells. Seeing me, you actually experience a disturbance in the sodium-potassium equilibrium across your neuron membranes. So all we have todo is send a few well-chosen molecules down into those cortical mitochondria, activate the right neurohumoral-synaptic transmission effector sites, and your fondest dreams come true. But you knowall this," he concluded, subdued.

No matter how great the initial chemistry is, if your values are on two different pages, the odds of your marriage working decrease significantly.

Mathematics is the cheapest science. Unlike physics or chemistry, it does not require any expensive equipment. All one needs for mathematics is a pencil and paper.

What do you call it when you end up right where you’re supposed to be?” Foster simply replies, “The perfect chemistry.
