Dr. Tyson and Dr. Michio Kaku are my 2 favorite science personalities. The passion and verve they exhibit is infectious, and that more than anything else is what makes people - especially young people - realize that science can be FUN. Why one of those 2 isn't the president's (any president) science advisor is beyond me.

Got to tell you one thing.

Prove that you deserve it
And help us to preserve it
Or being free will just be
Words and nothing more"
