Not entirely related, but I'm guessing you would enjoy reading Atomic Robo[1]. It's a comic (that has all 9 volumes for free online and the 10th is being released a page at a time daily) that follows an atomic powered robot built by Nikola Tesla.
Steven Hawking is a nemesis of Robo, Carl Sagan helped our hero get to Mars with Voyager, and there is a talking Dr. Dinosaur who claims that he time traveled to our time using crystals.
I recommend starting at the beginning.
