There are four individuals in the Science/Public Relations business that should be applauded as heroes of education: Neal deGrasse Tyson, Michio Kaku, Brian Cox, and Bill Nye.  These men (why are we lacking women in this niche?) embody the spirit of Carl Sagan in their passion for bringing science education to the masses.  Each has their own style, and while I love them all, there’s something so darn nostalgic about Bill Nye that I’ll always feel like a little kid whenever I watch him!
