It has been my observation that the best science-fiction is built upon a sturdy scaffolding of science fact. Let me quickly acknowledge that the craft of story-writing is the most important aspect: no matter how accurate the science is, the story can still be bad if crafted poorly. But if two stories are otherwise equal in the quality of their structure and other elements of craftsmanship, the great SF story is the one which incorporates real scientific ideas into its fabric.
So with that in mind, in the coming months I plan to bring you a series of blog posts sharing some things I learned through the course of my studies. Stay tuned for an exciting discussion on a particular aspect of planetary motion!
