A Quote by Ernest Rutherford

Radioactivity is shown to be accompanied by chemical changes in which new types of matter are being continually produced. .... The conclusion is drawn that these chemical changes must be sub-atomic in character.

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.

Oswald Avery

My ambition was to bring to bear on medicine a chemical approach. I did that by chemical manipulation of viruses and chemical ways of thinking in biomedical research.

Jonas Salk

But the prospects of designing chemical plants for industrial scale chemical processes seemed far less interesting than the chemical events that occur in biological systems.

Paul Berg

The chemical compounds are comparable to a system of planets in that the atoms are held together by chemical affinity. They may be more or less numerous, simple or complex in composition, and in the constitution of the materials, they play the same role as Mars and Venus do in our planetary system, or the compound members such as our earth with its moon, or Jupiter with its satellites... If in such a system a particle is replaced by one of different character, the equilibrium can persist, and then the new compound will exhibit properties similar to those shown by the original substance.

Jean-Baptiste Dumas

The question whether atoms exist or not... belongs rather to metaphysics. In chemistry we have only to decide whether the assumption of atoms is an hypothesis adapted to the explanation of chemical phenomena... whether a further development of the atomic hypothesis promises to advance our knowledge of the mechanism of chemical phenomena... I rather expect that we shall some day find, for what we now call atoms, a mathematico-mechanical explanation, which will render an account of atomic weight, of atomicity, and of numerous other properties of the so-called atoms.

August Kekule

One thing is all things. To resolve one matter, one must resolve all matters. Changing one thing changes all things. Once I made the decision to sow rice in the fall, I found that I could also stop transplanting, and plowing, and applying chemical fertilizers, and preparing compost, and spraying pesticides.

Masanobu Fukuoka

Biologists have long attempted by chemical means to induce in higher organisms predictable and specific changes which thereafter could be transmitted in series as hereditary characters. Among microorganisms the most striking example of inheritable and specific alterations in cell structure and function that can be experimentally induced and are reproducible under well defined and adequately controlled conditions is the transformation of specific types of Pneumococcus.

Oswald Avery

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.

Thomas Jefferson

We found out that we were dealing with a completely unregulated chemical, this chemical PFOA. This was a chemical that was a completely manmade material invented right after World War Two, didn't exist on the planet prior to the 1940s.

Robert Bilott

But the history of the changes produced by a universal idea is not a history of changes in the individual, but of changes brought about by the successive efforts of millions of individuals in the course of many generations.

Lafcadio Hearn

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.

Max Planck

If 90 percent or 95 percent of those - chemical stockpiles [in Syria] were eliminated, that's a lot of chemical weapons that are not right now in the hands of ISIL or Nusra or, for that matter, the regime.

Barack Obama

I find it hilarious that there are academics who try to analyse chemical changes in the brains of students while exposing them to gags.

Arthur Smith

Land degradation did not start with chemical agriculture. But chemical agriculture offered new tools for annihilation.

Joel Salatin

This would be a very good moment to institute a call for imposing the Chemical Weapons Convention on the Middle East. The actual Chemical Weapons Convention. Not the version that [Barack] Obama presented in his address to the nation and that media commentators repeat. What he said is that the convention bars the use of chemical weapons. He knows better. And so do the commentators. The Chemical Weapons Convention calls for banning the production, storage and use of chemical weapons, not just the use. So why omit production and storage?

Noam Chomsky

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).

Dmitri Mendeleev
