Chemical Composition Quotes

There is, as every schoolboy knows in this scientific age, a very close chemical relation between coal and diamonds. It is the reason, I believe, why some people allude to coal as "black diamonds." Both these commodities represent wealth; but coal is a much less portable form of property.

Not all chemicals are bad. Without chemicals such as hydrogen and oxygen, for example, there would be no way to make water, a vital ingredient in beer.

Over the years, humans have managed to incorporate nearly every element, light and weighty, common and obscure, into our daily lives. And given how small atoms are and how many of them there are all around us, it's almost certain that your body has at least brushed against an atom of every single natural element on the periodic table.

I will never use a substitute for butter. Margarine is one molecule away from eating plastic. If I'm going to eat that type of food, it's going to be the real deal.

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

Many years ago it was taught that plants and animals were composed of different materials: plants, of a chemical substance of three elements,- carbon, hydrogen, and oxygen; animals of one of four elements, nitrogen being added to the other three.

If a man is going to write on chemistry, he learns chemistry. The same is true of Christianity.

I was captured for life by chemistry and by crystals.

During the course of my research, I had had occasion to examine not only simple compounds, salts and oxides, but also a great number of minerals.

The organic material, as the laws of chemistry state, can neither be created nor destroyed.

What is man? He's just a collection of chemicals with delusions of grandeur.

Chemical compounds of carbon can exist in an infinite variety of compositions, forms and sizes. The naturally occurring organic substances are the basis of all life on Earth, and their science at the molecular level defines a fundamental language of that life.

It has long been known that the chemical atomic weight of hydrogen was greater than one-quarter of that of helium, but so long as fractional weights were general there was no particular need to explain this fact, nor could any definite conclusions be drawn from it.

I've started to think it must just be chemistry, in which case we're looking for the Shift and we haven't found it yet.

We speak erroneously of "artificial" materials, "synthetics", and so forth. The basis for this erroneous terminology is the notion that Nature has made certain things which we call natural, and everything else is "man-made", ergo artificial. But what one learns in chemistry is that Nature wrote all the rules of structuring; man does not invent chemical structuring rules; he only discovers the rules. All the chemist can do is find out what Nature permits, and any substances that are thus developed or discovered are inherently natural. It is very important to remember that.

...is the carbon molecule lined with thought?

And, to prevent mistakes, I must advertize you, that I now mean by elements, as those chymists that speak plainest do by their principles, certain primitive or simple, or perfectly unmingled bodies; which not being made of any other bodies, or of one another, are the ingredients of which all those called perfectly mixt bodies are immediately compounded, and into which they are ultimately resolved: now whether there be any such body to be constantly met with in all, and each, of those that are said to be elemented bodies, is the thing I now question.

But I must confess I am jealous of the term atom; for though it is very easy to talk of atoms, it is very difficult to form a clear idea of their nature, especially when compounded bodies are under consideration.

Physical changes take place continuously, while chemical changes take place discontinuously. Physics deals chiefly with continuous varying quantities, while chemistry deals chiefly with whole numbers.

I came here with the perfect chemist's perception. The formula they had was perfect and any added ingredient could make it go bad or worse.

In the visible world, the Milky Way is a tiny fragment; within this fragment, the solar system is an infinitesimal speck, and of this speck our planet is a microscopic dot. On this dot, tiny lumps of impure carbon and water, of complicated structure, with somewhat unusual physical and chemical properties, crawl about for a few years, until they are dissolved again into the elements of which they are compounded.

All we are is a lot of talking nitrogen.

Chemistry is like an indefinable thing. When it comes to people playing your best friend or your parents or anything like that, there's always different kind of element to chemistry.

But it was soon ascertained that this quaternary matter of the animal body was chemically the same in the plant, was elaborated there, and only appropriated by the animal.

It's all about chemistry. Talent alone won't get it done.
