I'm not easily inhibited by the fact that I don't know something about a subject. It doesn't stop me from dabbling in it.

I was a bad practicing physician because I was never sure of the diagnosis or of the treatment.

I got my Nobel Prize for my lab work.

When I was in high school, I became interested in cytochemistry: chemical analysis under the microscope, and trying to understand the composition of cells.

The central moral issue of science is that we do not have a science of peace and hardly know where to begin in building one.

If you wanted to dissect the structure of living cells, genetic analysis was an extremely powerful method, so my interest turned to that.

I get curious about new things. My real strength is going into a field that has not been investigated before, and finding new approaches to it.
