One day, sitting around with a group of undergraduate physics students, I listened as one made the bold statement: “If it can be imagined, it can be done.” The others nodded in agreement. It sounded like wisdom. It took me all of two seconds to violate this dictum as I imagined myself jumping straight up to the Moon. I may have asked if the student really thought what he said was true, but resisted the impulse to turn it into an impromptu teaching moment. Instead, I wondered how pervasive this attitude was among physics students and faculty. So I put together a survey and in this post report what I found. The overriding theme: experts say don’t count on a Star Trek future. Ever.
Science is a phenomenal institution. Sometimes I can’t believe we created this construct that works so incredibly well. It manages to convert human imperfections into a remarkably robust machine that has aided our growth juggernaut. Yet science seeks truth, and sometimes the truth is not what we want to hear. How will we respond? Will we kill the messenger and penalize the scientific institution for what is bound to be an increasing barrage of bad news this century as Earth fills beyond capacity?
I think for many people in our society, personal contact with science is limited to science classes in school or perhaps the dreaded science fair—or maybe as adults watching shows like Nova or tuning in to Shark Week on the Discovery Channel.
So let me take a moment to explain science as I have come to understand it. (You can skip if you already have a firm grip.)
