The dangerous man is the one who has only one idea, because then he'll fight and die for it.

Since I essentially knew nothing, I had an almost completely free choice.

Chance is the only source of true novelty.

Trying to determine the structure of a protein by UV spectroscopy was like trying to determine the structure of a piano by listening to the sound it made while being dropped down a flight of stairs.

There is no form of prose more difficult to understand and more tedious to read than the average scientific paper.

The meaning of this observation is unclear, but it raises the unfortunate possibility of ambiguous triplets; that is, triplets which may code more than one amino acid. However one would certainly expect such triplets to be in a minority.

It would appear that the number of nonsense triplets is rather low, since we only occasionally come across them. However this conclusion is less secure than our other deductions about the general nature of the genetic code.
