Science is a mosaic. Good science from disparate fields seems to conveniently converge to help us gradually gain a clearer overall view of our universe and make valid predictions based on that knowledge.
No one joined this rich mosaic of scientists together more sublimely and eloquently and passionately communicated this amassed wisdom better than Carl Sagan. Thanks Carl.
