Neil deGrasse Tyson has become more and more visible and outspoken these days. He's one of my favorite astrophysicist and champions of science. I believe the most important thing I ever learned in school was the scientific method, it's a good way to approach all unknowns in life. It encourages us to explore and dream. Dr. Tyson has a rare talent for communicating astronomical ideas in science with relevance and aproachability. A perfectly capable successor to the late great Carl Sagan.
