Stunning. Awe inspiring. For the first time I was lost in the wonderment of it all! :bow::yoga::clap::thinking::thumbsup::snowflake: Such reasoning! His reasoning was simple. Anyone could follow it. And yet...Oh So Profound! That was when it first came out and I caught a couple episodes on PBS. I think I was in high school. Carl Sagan was my absolute best science teacher ever! 47 now. Got the DVD set some years ago. Try as hard as I can to get the younger folk to share the insights (HUGE STUPENDOUS COLOSSAL INSIGHTS!). For this seminal series, I rate Carl Sagan (read his books too) among my heroes. The other one is Gandhi. Anybody else see it?
