What about the rest of life? Respect for the sanctity of life, if you believe that it begins at conception, cannot end at birth.

Almost all the students who make it to Caltech, one of the best scientific universities in the world, come from public schools. So it can be done.

I think we have lost our groove as a country. One of the reasons was the attack on 9/11. We got knocked off our game. From a country that always exported hope we went into the business of exporting fear.

I think that the drama of people rising up demanding their own freedom is one that resonates very deeply with America. I think that President Barack Obama has tried and would like to find a way to relate to the Arab Spring, but I think he also wants to be, rightly, very careful that we don't take it over. It is very important that they own this. He is trying to influence it this way but without, "We're so never going to go to the extreme of Iraq and putting boots on the ground again."

If I were advising President Obama, since he's the one running, I would have made his campaign very simple. I promise that in four years, I will get more Americans, as many as I possibly can, the opportunity and access to some form of post-secondary education. I want more of them to graduate high school with the skill-set of post-secondary education and I want more of them to be able to obtain that post-secondary education. This is the only way we are going to close the income gap.

Remember, the difference between the world frozen over, in an ice ball, and the warming period we're in now is just 6 degrees centigrade. A change of just 1 degree can have a huge effect.

I don't think the Arab Spring had much to do with energy. I think it was just the opposite, in fact. I think the Arab Spring happened because particularly young people knew they were living in a context where they could not realize their full potential, that they are being kept down by their own governments.
