Like thousands of other boys, I had a little chemical laboratory in our cellar and think that some of our friends thought me a bit crazy.

Science is the search for truth.

We may, I believe, anticipate that the chemist of the future who is interested in the structure of proteins, nucleic acids, polysaccharides, and other complex substances with high molecular weight will come to rely upon a new structural chemistry, involving precise geometrical relationships among the atoms in the molecules and the rigorous application of the new structural principles, and that great progress will be made, through this technique, in the attack, by chemical methods, on the problems of biology and medicine.

[Instead of collecting stamps, he collected dictionaries and encyclopaedias:] Because you can learn more from them.

No evidence compels the conclusion that the minimum required intake of any vitamin comes close to the optimum intake that sustains good health.

Life ... is a relationship between molecules.
