A friend of mine from college is a physics professor who does a lot of stuff with the space station and the new Google Lunar X Prize, that awards up to $30 million for the first non-governmental organization to land a robot on the moon. He likes to get his students involved and has a gift for expressing things in terms they can immediately grasp. “The robot,” he tells them, “can be small. Think of an iPhone with wheels.”
When something has penetrated the collective consciousness the way the iPhone has, it changes the way we look at what is possible.
