They have a lot of extreme physics going on inside them and scientists use them to test theories of relativity on a cosmic scale. Einstein’s theories are checking out pretty well so far.

There are many battles. There’s so much that needs to be done. We need to protect the environment. Save this little planet. Not just this little piece of real estate we call America, but save the planet.

I certainly want to continue trying to understand how the global environment functions. The earth as a system is a very complicated one. And to understand it, we need very many disciplines, very many different scientists working together. I want to continue working with my specialty, which is chemistry, with the atmosphere. There is still much to learn about chemical reactions that occur out there in the air, in the atmosphere. So one of my projects now is to really learn more about this pollution that occurs in cities and that is spreading more through the globe. To learn it in enough detail so we can better tackle it, we can better come up with new ways of using energy, for example, that are not so damaging to the environment.

We have all these interesting challenges now. No one knows whether automation and robotics, nanotechnology, will kill more jobs than it creates. If it does, that presents a serious problem. What are we going to do? Have a few of us work to support everybody else, or shorten the workweek for everybody? If so, how do we get from here to there? No one knows yet how we’re going to stop cyber terrorism from wrecking honest discourse in democracy and maybe putting our very lives at risk.

There were so many needs for us to continue to work for freedom, because I didn’t think that we should have to be treated in the way we were, just for the sake of white supremacy, because it was designed to make them feel superior, and us feel inferior. That was the whole plan of racially enforced segregation.

My family, I would say, my mother, and my maternal grandparents. I grew up with them. My mother was a teacher in a little school, and she believed in freedom and equality for people, and did not have the notion that we were supposed to live as we did, under legally enforced racial segregation. She didn’t believe in it.

We work with young people, from the ages of 11 to 17. Our main program is the Pathways to Freedom. And we’ll be going from Memphis, Tennessee through ten other states, and Washington, DC, and to Canada. It began July 13th and ends August 8th. We hope to take as many young people and their chaperons as possible throughout these areas, and stop and have workshops and programs. They’ll be traveling in buses, and we hope that will inspire and give them a sense of history and also to encourage them to be concerned about their self and history and motivated to reach their highest potential.

The advice I would give any young person is, first of all, to rid themselves of prejudice against other people and to be concerned about what they can do to help others. And of course, to get a good education, and take advantage of the opportunities that they have. In fact, there are more opportunities today than when I was young.

As I look back on those days, it’s just like a dream. The only thing that bothered me was that we waited so long to make this protest and to let it be known wherever we go that all of us should be free and equal and have all opportunities that others should have.

I would have to take longer than a minute to give my whole synopsis of my life, but I want to let you know that all of us should be free and equal and have equal opportunity and that is what I’m trying to instill and encourage and inspire young people to reach their highest potential.
