The limits on your enlightenment come not from the age you stopped going to school but from the age you stopped being curious.

I can't tell you how many people say they were turned off from science because of a science teacher that completely sucked out all the inspiration and enthusiasm they had for the course.

My popularity does not derive from me pandering to people. People came to me. I don't tell anyone to follow me on Twitter. I don't tell people to like my Facebook page. I don't tell people to fill the venue. I'm offered to people, and then people come.

Science, and its impact on a person's livelihood is the common denominator.
