“The conclusion is inescapable that non-luminous matter exists beyond the optical…” — Vera Rubin

I try to do my science in a moral way, and, I believe that, ideally, science should be looked upon as something that helps us understand our role in the universe.

I'm Jewish, and so religion, to me, is a kind of moral code and a kind of history.

In my own life, my science and my religion are separate.

We need senators who have studied physics and representatives who understand ecology.
