After my mother died, I learned that she'd had a scholarship to the University of Nebraska, but - in kind of a tradition that females don't do things like that - her father prevented her from going. She always said that she wasn't allowed to go to college, but until she died, I never knew that she'd had this scholarship.

A lot of missions for NASA or experiments on accelerators happen through a whole process of scientific retreats, long-range planning, forming collaborations to do studies - all this kind of stuff. It's very democratic.

When I was really young, my ambition wasn't to do science. I didn't really know that I could. It was to write a great novel.

Everything we know about the universe is studied by using telescopes or other instruments that look at visible light, infrared, ultraviolet or X-ray - different wavelengths of electromagnetic interactions. Only 4 percent of what's in the universe gives off electromagnetic radiation, so we don't have any handle on the rest.
