ALICE WINKLER: If you're in your 60s, you might first picture Gidget when you hear Sally Field's name. That's the silly, surfing teenager she played on TV when she was, herself, still a teen.

Most scientific research has practical ends. But some still pursues goals better described by the field's original name: " natural philosophy" . One of its most philosophical questions is, " Is there life elsewhere in the universe" ?

大多数科学研究都有实际的目的。但有些人仍然追求这个领域的原名" 自然哲学" 所描述的更好的目标。其中一个最哲学的问题是，" 宇宙中其他地方有生命吗？"
