The world could use more scientists like Leon Lederman, and not just because his Nobel Prize winning research led to the discovery of the muon neutrino.
The world could use more scientists like Lederman because he's the kind of person who sets aside time to set up shop on a New York City street corner (he's also made appearances in Chicago) and simply talk about science. What's more, he does it in a lucid, charming and engaging way.
There's something to be said for taking the wonder and curiosity of science out of the lab and onto the streets — that is, plucking it out of an environment that many in the public consider to be inaccessible and confusing, and dropping it somewhere that those same people might have a chance to ask interesting scientific questions, and maybe pick up a nice dose of enlightenment on their morning commute. If this kind of thing were made common practice, something tells us the world would be a better place for it.
