Man himself is a mysterious object, and the tools to probe his physiologic nature and function have developed only slowly through the millennia.

To primitive man, the sky was wonderful, mysterious and awesome, but he could not even dream of what was within the golden disk or silver points of light so far beyond his reach.

Perhaps the earliest memories I have are of being a stubborn, determined child. Through the years my mother has told me that it was fortunate that I chose to do acceptable things, for if I had chosen otherwise, no one could have deflected me from my path.

The failure of women to have reached positions of leadership has been due in large part to social and professional discrimination. In the past, few women have tried, and even fewer have succeeded.

I wasn't handed college or graduate school or anything else on a silver platter. I had to work very hard, but I did it because I wanted to. That's the real key to happiness. I think unhappy people are those who feel that circumstances are forcing them into a pattern. Happy people are not slaves to the system.

Everything's a real passion to me - my children, my family, my work, travel. I don't play tennis, I don't play music, but I have a great time.
