Carl changed my life when i was a young teenager and first watched 'Cosmos' on the small tube.
Not to the extent of Neil deGrasse Tyson, but still changed my life.
I will forever think of Issac Asimov as the Grand Master of Science Fiction and the reason i really got excited about the sciences in the first place, but Carl validated that for me.
For some reason i was thinking about one of the many times i saw Carl on The Tonight Show with Johnny Carson and stumbled upon this awesome compilation of Carl's wisdom.
