I had left teaching, which I enjoyed, because I realized I couldn't get tenure at a research university.

Research is all about teaching and learning. This demonstrates what students can do and achieve at a research university.

Certainly by the time I was in seventh grade, I knew I had to have a long education if I wanted to become an astronomer, but I figured I'd try it, and if I didn't get far enough, I could always end up teaching in high school or math or physics.

What changed my mind about getting a doctorate is the university stressed research over teaching. I wanted to teach.

I wondered had I really oversold the Hubble. I have to admit that, since, I have been convinced that I didn't.

We all started somewhere. When I started teaching at the university level, I didn't want to teach freshmen. Then I saw that you have the biggest impact on people who have the least experience. I have a special place in my heart for the novice player.
