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.

Everybody has to learn for the first time.

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

I hope I've lived a life of science whose style will encourage younger people.

To have the recognition of your colleagues is great. The public attention is a mixed blessing.

If it takes you 20 or 25 years to establish yourself in one field, you really ought to be careful not to stray too far.

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.
