The ultimate aim of the modern movement in biology is in fact to explain all biology in terms of physics and chemistry.

Francis Crick

Almost all aspects of life are engineered at the molecular level, and without understanding molecules we can only have a very sketchy understanding of life itself.

Protein synthesis is a central problem for the whole of biology, and that it is in all probability closely related to gene action.

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

When you start in science, you are brainwashed into believing how careful you must be, and how difficult it is to discover things. There’s something that might be called the ‘graduate student syndrome’; graduate students hardly believe they can make a discovery.
