I take no pleasure in the fact that the scientific predictions I’ve relayed to popular audiences turn out to be true.

George Bush taking credit for the wall coming down is like the rooster taking credit for the sun rising.

Science has a culture that is inherently cautious and that is normally not a bad thing. You could even say conservative, because of the peer review process and because the scientific method prizes uncertainty and penalises anyone who goes out on any sort of a limb that is not held in place by abundant and well-documented evidence.

I will tell you that what gives me a sense of joy is having work to do that justifies pouring every ounce of energy I have into it. That's really a blessing to have in your life. And it gives you energy back when you have the privilege of doing work that makes you feel that way.

I think that more diversity is a good thing, and fresh points of view articulated by people who are committed to excellence in journalism is a beneficial change in the American media landscape.
