Verily, chemistry is not a splitting of hairs when you have got half a dozen raw Irishmen in the laboratory.

We are not only warming the ocean and the planet as a whole, but we are also acidifying the ocean and changing its chemistry.

We learned early on that we had chemistry and I was so grateful for that. It's like one of the few magical things about film that still exists.

We define organic chemistry as the chemistry of carbon compounds.

We'd like to make it [bucky fiber] in a continuous fiber, roll it on a drum, and go fishing with it.

When you encourage someone, it literally changes their brain chemistry to be able to perform... sends fuel to the brain.

Well, I was always... I used to get 100% in physics and chemistry and mathematics (well, maybe a couple of points off in mathematics), and that was in high school.

When love and discipline come together you have great chemistry.

When you have chemistry with a potential hire, they will most likely become a great employee.

What people don't understand is when punk started it was so innocent and not aware of being looked at or being a phenomenon and that's what everyone gets wrong. You can't consciously create something that's important, it's a combination of chemistry, conditions, the environment, everything.

You can have a great time on a film and the chemistry can seem great but then you look at the finished film and it just doesn't quite gel, something doesn't quite work.

Where there is no love, a person's faithfulness to the marriage bond is probably against nature.

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.

Why don't we have the chemistry that Leonardo DiCaprio and Kate Winslet had in Titanic? I'll tell you one reason: Because we're not in a movie!

Why do we always fight?” she whispered. “You know why.” Yeah, she did. “It’s science.” “Combustible chemistry,” he agreed. “Dangerous.

William knows that science and magic are the same thing; magic is only science that hasn't been explained yet. Tonight he has made chemistry into magic for her.

You can make low-budget film as long as there is something compelling about the characters. There is a believability in the chemistry and a likeability amongst the characters.

You can still have chemistry on screen without getting on with the person. But it just makes your job a lot easier if you don't have to gird your loins, if that's not quite the right phrase, every time you're going to do a scene with that person.

You can't control chemistry. You can't control, you know, just similar aesthetics creatively. And, you know, David and I didn't know each other prior to this. And we get along famously. So it's - I feel very lucky.

You mix a bunch of ingredients, and once in a great while, chemistry happens.

You don't buy chemistry, nor do you manufacture it, it is what it is.

Your illness is not your identity. Your chemistry is not your character.

Svante Arrhenius, recipient of the Nobel Prize in chemistry (1903), was a declared atheist and the author of The Evolution of the Worlds and other works on cosmic physics.

Your sexual attributes are simply chemistry and setups within your DNA. They are given by agreement as gifts for you to experience in this life.

About 13.5 billion years ago, matter, energy, time and space came into being in what is known as the Big Bang. The story of these fundamental features of our universe is called physics. About 300,000 years after their appearance, matter and energy started to coalesce into complex structures, called atoms, which then combined into molecules. The story of atoms, molecules and their interactions is called chemistry. About 3.8. billion years ago, on a planet called Earth, certain molecules combined to form particularly large and intricate structures called organisms. The story of organisms is called biology. About 70,000 years ago, organisms belonging to the species Homo sapiens started to form even more elaborate structures called cultures. The subsequent development of these human cultures is called history.

About eight days ago I discovered that sulfur in burning, far from losing weight, on the contrary, gains it; it is the same with phosphorus; this increase of weight arises from a prodigious quantity of air that is fixed during combustion and combines with the vapors. This discovery, which I have established by experiments, that I regard as decisive, has led me to think that what is observed in the combustion of sulfur and phosphorus may well take place in the case of all substances that gain in weight by combustion and calcination; and I am persuaded that the increase in weight of metallic calyxes is due to the same cause... This discovery seems to me one of the most interesting that has been made since Stahl and since it is difficult not to disclose something inadvertently in conversation with friends that could lead to the truth I have thought it necessary to make the present deposit to the Secretary of the Academy to await the time I make my experiments public.

A demonstrative and convincing proof that an acid does consist of pointed parts is, that not only all acid salts do Crystallize into edges, but all Dissolutions of different things, caused by acid liquors, do assume this figure in their Crystallization; these Crystalls consist of points differing both in length and bigness from one another, and this diversity must be attributed to the keener or blunter edges of the different sorts of acids.

She discovered in a series of beautifully executed researches the fundamental distinction between carbons that turned on heating into graphite and those that did not. Further she related this difference to the chemical constitution of the molecules from which carbon was made. She was already a recognized authority in industrial physico-chemistry when she chose to abandon this work in favour of the far more difficult and more exciting fields of biophysics. {Bernal on the death of scientist Rosalind Franklin}

A Dr van 't Hoff of the veterinary college at Utrecht... finds it a less arduous task to mount Pegasus (evidently borrowed from the veterinary school) and to proclaim in his La Chemie dans l' espace how, during his bold fight to the top of the chemical Parnassus, the atoms appeared to him to have grouped themselves together throughout universal space. ... I should have taken no notice of this matter had not Wislicenus oddly enough written a preface to the pamphlet, and not by way of a joke but in all seriousness recommended it a worthwhile performance.

Balard did not discover bromine, rather bromine discovered Balard. {Comment on Antoine Jérôme Balard, discoverer of bromine.}

Lister saw the vast importance of the discoveries of Pasteur. He saw it because he was watching on the heights, and he was watching there alone.

Epicurus... supposes not only all mixt bodies, but all others to be produced by the various and casual occursions of atoms, moving themselves to and fro by an internal principle in the immense or rather infinite vacuum.

Atoms are round balls of wood invented by Dr. Dalton. (Answer given by a pupil to a question on atomic theory, as reported by Sir Henry Enfield Roscoe.)

As chemists, we must rename [our] scheme and insert the symbols Ba, La, Ce in place of Ra, Ac, Th. As nuclear chemists closely associated with physics, we cannot yet convince ourselves to make this leap, which contradicts all previous experience in nuclear physics.

As there are six kinds of metals, so I have also shown with reliable experiments... that there are also six kinds of half-metals: a new half-metal, namely Cobalt regulus in addition to Mercury, Bismuth, Zinc, and the reguluses of Antimony and Arsenic.

At the age of 48, my body had become a chemistry experiment that I was constantly changing the composition of the chemicals in it to find beneficial reactions.

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.

. . . and there was for a moment an unbreakable bond between us: the eternal bond of chemistry. I glowed with all the fire of a newborn galaxy.

As the physicist Paul Davies puts it, 'If everything needs everything else, how did the communities of molecules ever arise in the first place?' It is rather as if all the ingredients in your kitchen somehow got together and baked themselves into a cake - but a cake that could moreover divide when necessary to produce more cakes. It is little wonder that we call it the miracle of life. It is also little wonder that we have barely begun to understand it.

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.)

At the moment I am occupied by an investigation with Kirchhoff which does not allow us to sleep. Kirchhoff has made a totally unexpected discovery, inasmuch as he has found out the cause for the dark lines in the solar spectrum and can produce these lines artificially intensified both in the solar spectrum and in the continuous spectrum of a flame, their position being identical with that of Fraunhofer’s lines. Hence the path is opened for the determination of the chemical composition of the Sun and the fixed stars.

Attraction isn't wrong. People can’t help who they are drawn to and they certainly can’t control affinity, as uncommon as it is. What is wrong is acting on inclination if it hurts someone else, namely a significant other.

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.

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.

But who could resist the erotic lives of atoms and molecules - the violent passion of electrostatic attractions, the comfortable mutuality of covalent bonds, the gentle air kisses of van der Waals forces? The rules governing the couplings and uncouplings of tiny particles seemed to me as fascinating as the kinship rules of what we still called "primitive" societies - with the revulsion of like-charged particles, for example, functioning as a kind of incest taboo.

Brittany Ellis," Mrs. Peterson says, pointing to the table behind Colin. I unenthusiastically sit on the stool at my assigned place. "Alejandro Fuentes," Mrs. Peterson says, pointing to the stool next to me. Oh my God. Alex . . . my chemistry partner? For my entire senior year! No way, no how, SO not okay. I give Colin a "help me" look as I try to avoid a panic attack. I definitely should have stayed at home. In bed. Under the covers. Forget not being intimidated. "Call me Alex." Mrs. Peterson looks up from her class list and regards Alex above the glasses on her nose. ' Alex Fuentes," she says, before changing his name on her list. "Mr. Fuentes, take off that bandanna. I have a zero tolerance policy in my class. No gang-related accessories are allowed to enter this room. Unfortunately, Alex, your reputation precedes you. Dr. Aguirre backs my zero tolerance policy one hundred percent ... do I make myself clear?" Alex stares her down before sliding the bandanna off his head, exposing raven hair that matches his eyes. "It's to cover up the lice," Colin mutters to Darlene, but I hear him and Alex does, too. "Vete a la verga," Alex says to Colin, his hard eyes blazing. "Collate el hocico." "Whatever, dude," Colin says, then turns around. "He can't even speak English." "That's enough, Colin. Alex, sit down." Mrs. Peterson eyes the rest of the class. "That goes for the rest of you, as well. I can't control what you do outside of this room, but in my class I'm the boss." She turns back to Alex. "Do I make myself clear?" "Si, señora," Alex says, deliberately slow.

But Cecilia, having learned modern forms of snobbery at Cambridge, considered a man with a degree in chemistry incomplete as a human being.

Came the day of the first trial. The propellants were hydrazine and WFNA. We were all gathered around waiting for the balloon to go up, when Dr. Milton Scheer(Uncle Milty) warned, "Hold it - the acid valve is leaking!" "Go ahead - fire anyway!" Paul ordered. I looked around and signaled to my own gang, and we started backing away gently, like so many cats with wet feet.

chemistry is you touching my arm and it setting fire to my mind.

Chemistry is great, but eventually your relationship moves out of the laboratory.
