Barrow Topic(s): Science More In Science "Every known fact in natural science was divined by the presentiment of somebody, before it was actually verified."― Ralph Waldo Emerson "I don’t recall any interest in science in particular. It came later in college."― Ellen Ochoa "I didn’t mind studying. Obviously math and the physical science subjects interested me more than some of the more artistic subjects, but I think I was a pretty good student."― Alan Shepard
