I'd like to put in a vote for the intrinsic fascination of science.

My ambitions were already very clearly fixed by the time I was 6 or 7.

By the time I was 12 or 13, I was studying biochemistry textbooks.

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

I certainly saw science as a kind of calling, and one with as much legitimacy as a religious calling.

I have many shortcomings. I feel very lucky to have been able to have what I've had.

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