"The universe is full of mysteries. And that's a good thing."

"Science is a way of thinking much more than it is a body of knowledge."

"If you want to know what it means to be alive, look at the stars."

"If you are a scientist, you are a scientist. You don't have to be a 'black scientist' or a 'woman scientist.'"

"The great thing about science is that it's a self-correcting enterprise. It doesn't care about your feelings."
