Growing up in Hampton, the face of science was brown like mine.

I knew a lot of black scientists, engineers, and mathematicians, and female mathematicians and engineers, women of all backgrounds. So this idea that anyone could be an engineer, a mathematician, or whatever, was something that I had grown up with and thought was really normal.

Our next-door neighbour taught physics at Hampton University. Our church abounded with mathematicians. Supersonics experts held leadership positions in my mother's sorority, and electrical engineers sat on the board of my parents' college alumni associations.

My dad worked at NASA his whole career; he's a research scientist.

The chief duty of government is to keep the peace and stand out of the sunshine of the people.

My grandfather was originally from the south of China before he emigrated to Malaysia pre-World War II. And I wanted to learn more about the history of the country of my ancestors. I knew I wanted a narrative set in contemporary Beijing. I was really interested in the effect of the rapid social and economic change on ordinary citizens in China.

If we're going to ask our kids at age 18 to go off to war and die for their country, I don't see any problem with asking them at age 16 to think about what that might mean.

I always feel I had a very lucky life. For example, I sure didn't want to go in the army: when I was drafted in the Korean War, I wanted to go as a photographer. But luckily, they put me in the infantry - luckily because the official photographer was photographing the medal awarding and all the official situations.
