One of the biggest problems with the world today is that we have large groups of people who will accept whatever they hear on the grapevine, just because it suits their worldview—not because it is actually true or because they have evidence to support it. The really striking thing is that it would not take much effort to establish validity in most of these cases… but people prefer reassurance to research.

I don't like trying to influence politicians, who are themselves representative of huge numbers of people. As an educator, I'd rather enlighten the people and educate the people and let they be the ones who put the pressure on their elected officials.

There's the anti-intellectual movement in society and I don't blame them entirely for feeling that way because we all know people, I have many colleagues where you try to hang out with them and they make you feel bad for not knowing what they know.

All was cooked in the fiery hearts of long vanished stars. … The cosmos is also within us. We're made of star stuff. We are a way for the cosmos to know itself.
