Thomas Jefferson Quotes

I shall attack Chemistry, like a Shark.

If you had to sum up chemistry in one sentence, it might be this: Atoms need to have full shells of electrons to feel satisfied, and different elements steal, shed, or borrow different numbers of electrons to achieve a full shell.

Chemistry is the melodies you can play on vibrating strings.

Did chemistry theorems exist? No: therefore you had to go further, not be satisfied with the quia, go back to the origins, to mathematics and physics. The origins of chemistry were ignoble, or at least equivocal: the dens of the alchemists, their abominable hodgepodge of ideas and language, their confessed interest in gold, their Levantine swindles typical of charlatans and magicians; instead, at the origin of physics lay the strenuous clarity of the West-Archimedes and Euclid.

I have been so electrically occupied of late that I feel as if hungry for a little chemistry: but then the conviction crosses my mind that these things hang together under one law & that the more haste we make onwards each in his own path the sooner we shall arrive, and meet each other, at that state of knowledge of natural causes from which all varieties of effects may be understood & enjoyed.

You've got a chemistry class; I want a piece of your mind; You don't know what you started when you mixed it up with mine.

Chemistry is a class you take in high school or college, where you figure out two plus two is 10, or something.

There's nothing colder than chemistry.

My special fascination has been to understand better the world of chemistry and its complexities.

Chemistry happens naturally, and there's not really a lot you can do intentionally to create it.

I was in AP chemistry in high school, and I really liked it.

I believe that the science of chemistry alone almost proves the existence of an intelligent creator.

I do not know if I am mistaken, but it seems that one can obtain more truths, important to Humanity, from Chemistry than from any other Science.

I figure I've done what I could do, more or less, and now I'm going back to being a chemical; all we are is a lot of talking nitrogen, you know.

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

For me chemistry represented an indefinite cloud of future potentialities which enveloped my life to come in black volutes torn by fiery flashes, like those which had hidden Mount Sinai. Like Moses, from that cloud I expected my law, the principle of order in me, around me, and in the world... I would watch the buds swell in spring, the mica glint in the granite, my own hands, and I would say to myself: "I will understand this, too, I will understand everything.

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 learning to unravel, was poetry.

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.

The magnitude of the atomic weight determines the character of the element, just as the magnitude of the molecule determines the character of a compound body.

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, until my childhood, not that long ago, was regarded as a calculating device. Because you couldn't reduce to physics. So it's just some way of calculating the result of experiments. The Bohr atom was treated that way.

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.

Elements which are similar as regards their chemical properties have atomic weights which are either of nearly the same value (eg. Pt, Ir, Os) or which increase regularly (eg. K, Ru, Cs).

You have to look at how chemistry develops.

The chemist, whose science is immediately concerned with the combinations of atoms, has rarely found it necessary to discuss their shapes, and gives them no particular forms in his diagrams. That does not mean that the shapes are unimportant, but rather that the older methods could not define them.
