Understand something. Fall back from the old times and ways of doing things. Chemistry is deeper than the feels.

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.

We may regard the cell quite apart from its familiar morphological aspects, and contemplate its constitution from the purely chemical standpoint. We are obliged to adopt the view, that the protoplasm is equipped with certain atomic groups, whose function especially consists in fixing to themselves food-stuffs, of importance to the cell-life. Adopting the nomenclature of organic chemistry, these groups may be designated side-chains. We may assume that the protoplasm consists of a special executive centre (Leistungs-centrum) in connection with which are nutritive side-chains... The relationship of the corresponding groups, i.e., those of the food-stuff, and those of the cell, must be specific. They must be adapted to one another, as, e.g., male and female screw (Pasteur), or as lock and key (E. Fischer).

We are at the dawn of a new era, the era of 'molecular biology' as I like to call it, and there is an urgency about the need for more intensive application of physics and chemistry, and specially of structure analysis, that is still not sufficiently appreciated.

We —I mean to say we mammals — who in general do not have problems about obtaining water, have learned to wedge it into the urea molecule, which is soluble in water, and as urea we free ourselves of it; other animals, for whom water is precious (or it was for their distant progenitors), have made the ingenious invention of packaging their nitrogen in the form of uric acid, which is insoluble in water, and of eliminating it as a solid, with no necessity of having recourse to water as a vehicle. In an analogous fashion one thinks today of eliminating urban garbage by pressing it into blocks, which can be carried to the dumps or buried inexpensively.

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.

We would sit down fifteen, sometimes twenty, to the table on seder nights: my parents; the maiden aunts - Birdie, Len, and before the war, Dora, sometimes Annie; cousins of varying degree, visiting from France or Switzerland; and always a stranger or two would come. There was a beautiful, embroidered tablecloth which Annie had brought us from Jerusalem, gleaming white and gold on the table. My mother, knowing that sooner or later there would be accidents, always had a preemptive "spill" herself - she would manage somehow, very early in the evening, to tip a bottle of red wine onto the tablecloth, and thereafter no guest would be embarrassed if they knocked over a glass. Though I know she did this deliberately, I could never predict how or when the "accident" would occur; it always looked absolutely spontaneous and authentic. (She would immediately spread salt on he wine stain, and it became much paler, almost disappearing; I wondered why salt had this power.)

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

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

What is chemistry in a relationship, Really? Chemistry can be spontaneous combustion that excites, incites, often harms. But not understood. Chemistry can also be that which is studied, intentional, and knows how to be repeated and improved upon. Do you have the right chemistry?

What is fear but the worry of physical harm coming to the body? The notion that you will lose something-a person, a thing, your memories, yourself. Does he experience that? Do any of them experience that when they can just be put back together again?

What is like chemistry?" "Well. Life." "It's an outrageous farce, Oliver, with an incompetent producer...

You are so beautiful,” he whispered, kissing her softly on the lips. “I can’t believe I got to have you.” “You’re the only one who has,” Carrie smiled, “And I wouldn’t have had it any other way.

When he put the old-fashioned mechanical toy on her palm, she stopped breathing. It was a tiny representation of an atom, complete with colored ball bearings standing in for neutrons, protons, and on the outside, arranged on arcs of fine wire, electrons. Turning the key on the side made the electrons move, what she’d thought were ball bearings actually finely crafted spheres of glass that sparked with color. A brilliant, thoughtful, wonderful gift for a physics major. “Why magnesium?” she asked, identifying the atomic number of the light metal. His hand on her jaw, his mouth on her own. “Because it’s beautifully explosive, just like my X.

Who would not have been laughed at if he had said in 1800 that metals could be extracted from their ores by electricity or that portraits could be drawn by chemistry. {Commenting on Henri Becquerel's process for extracting metals by voltaic means.}

You are who you are because others say that's who you are. You can try to change who you are but it will only change the views of others who think you are what you really aren't.

And the actual achievements of biology are explanations in terms of mechanisms founded on physics and chemistry, which is not the same thing as explanations in terms of physics and chemistry.

You feel that, Harper?” She snatched back her hand. “If you mean my goodwill evaporating with every second you’re standing here, then, yeah, I feel it.” “I think we’re havin’ a thing.” They were. Oh, God, they were.

You have heard of the new chemical nomenclature endeavored to be introduced by Lavoisier, Fourcroy, &c. Other chemists of this country, of equal note, reject it, and prove in my opinion that it is premature, insufficient and false. These latter are joined by the British chemists; and upon the whole, I think the new nomenclature will be rejected, after doing more harm than good. There are some good publications in it, which must be translated into the ordinary chemical language before they will be useful.

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.

You know you're a chemist when you expect your washing machine not just to have "spin" but to have "lock and shim" as well. And when your clothes don't come out clean you wonder if it's because you chose the wrong solvent from the menu or something, or maybe it ran out of N2. Or if the machine was tuned to "pants" rather than "socks" nucleus. And then you think "I'll submit it for service

You must love chemistry even when it is not working. You must love chemistry unconditionally.

you're Shane, right?' He inched away from her and managed a quick nod as he twisted the rag he held in his fingers. 'Heidi sad you were willing to teach me how to ride.' Her expression shifted from entertained to confused, as if she was wondering why no one had mentioned he was a can or two shy of a six-pack. 'A horse,' he clarified, then wanted to kick himself. What else but a horse? Did he think she was here to learn to ride his mother's elephant? One corner of Annabelle's perfect, full mouth twitched. 'A horse would be good. You seem to have several.' He wanted to remind himself that he was usually fine around women. Smooth even. He was intelligent, funny and could, on occasion, be charming. Just not now, with his blood pumping and his brain doing nothing more than shouting "it's her, it's her" over and over again. Chemistry, he thought grimly. It could turn the smartest man into a drooling idiot. Here he was, proving the theory true.

A good relationship is all about balance and chemistry.

A multitude of aspects of the natural world that were considered miraculous only a few generations ago are now thoroughly understood in terms of physics and chemistry.

Wherever we look, the work of the chemist has raised the level of our civilization and has increased the productive capacity of our nation.

At school I briefly wanted to be a palaeontologist, but I was no good at chemistry and physics.

Chemistry [between people] is not the easiest thing to evaluate. Just like talent and health, these things can change.

At one point I wanted to work for NASA and be an astrophysicist, so I did physics, math, and chemistry before realizing I probably wasn't quite smart enough to do that. But I am still hugely interested in cosmology and astrophysics. That is my geeky subject area.

Chemistry is necessarily an experimental science: its conclusions are drawn from data, and its principles supported by evidence from facts.

Chemistry does not guarantee compatibility.

Chemistry on film is like chemistry in real life, it's either there or it isn't.

Chemistry, unlike other sciences, sprang originally from delusions and superstitions, and was at its commencement exactly on a par with magic and astrology.

At Harvard I majored in chemistry with a strong inclination toward math.

Chemistry has been termed by the physicist as the messy part of physics, but that is no reason why the physicists should be permitted to make a mess of chemistry when they invade it.

Chemistry is a hard thing. I don't think you can force it, and it doesn't necessarily mean that you have to have great chemistry outside of work. It's just something that sparks on screen or doesn't.

Chemistry is the melodies you can play on vibrating strings.

Chemistry's a tricky thing, and if I'm not feeling it, I'm not gonna pretend.

Chemistry ceases to improve when one element is found from which all others are deductible. Physics ceases to progress when one force is found of which all others are manifestations. So religion ceases to progress when unity is reached, which is the case with Hinduism.

Chemistry can be a good and bad thing. Chemistry is good when you make love with it. Chemistry is bad when you make crack with it.

Chemistry is so important in a great kiss. You can act your way through anything, but its hard with a kiss.

Chemistry is not anything an executive producer or writer can orchestrate or plan; you just hope for it.

Einstein believed deeply that science should transcend national and ethnic divisions. But he watched physicists and chemists become the purveyors of weapons of mass destruction in the early 20th century.

Cookery is not chemistry. It is an art.

Everything that goes into making a film, when it's the finished product, us as the actors look at the film and go: "Oh man, OK, on that day we were doing whatever the circumstances were on that day...." So much goes into it and it's all so incredibly calculated that the behind-the-scenes chemistry that exists between all of us is sometimes forgotten - you can't act that. We've all come together and held hands through each of the processes that I've been a part of.

Flirting is conversational chemistry.

Every practice, every film session, every game will help our chemistry.

Espresso is a miracle of chemistry in a cup.

Geology differs from physics, chemistry, and biology in that the possibilities for experiment are limited.

Few scientists acquainted with the chemistry of biological systems at the molecular level can avoid being inspired.
