I went to an awards ceremony today for the big award I got through my department, and the sponsor of the award himself showed up to give it to me (and two others from the U of M - other departments). He was very old, and very humorous, and told a funny story about the Martians. This is his story, as well as I can remember it:
Some astronauts landed on Mars, and met some Martians. The Martians gave them a tour and showed them where they worked and ate and how they lived. Then the Martians showed the astronauts the factory where Martians are made. "Wow!" the astronauts said, "That's not at all how people are made!" The Martians said "Oh? How are people made?" and the astronauts explained it to the Martians. The Martians jumped back in surprise and said "My oh my! That's how we make cars!"
His point was something like this: NEVER simply believe in something just because everyone else believes it, you should question authority and question long-held beliefs and assumptions and especially question anyone with a strong opinion about anything.
I really liked this guy, and I'm glad I got the award so I could meet him.
