I always enjoy it when fantasy makes at least some kind of scientific sense.

The video mentions fire-breathing dragons. A while back I found this explanation, apparently written by someone with a background in organic chemistry, of how dragon fire might work. If I ever had a cause to include dragons in a story, this is probably how they would breathe fire.

This would have been a cool way to learn about geology back in my college days! A group of geologists who are also fantasy enthusiasts have reconstructed a geological history of Westeros, the setting of George R. R. Martin’s Game of Thrones. By looking at the observations of characters in the novels themselves, place names, and even fan wikis, they have reconstructed 500 million years of geological history, which they share in a series of blog posts under the name “A Geology of Game of Thrones.”

I love it when fantasy fiction is (or can be shown to be) scientifically coherent within its own premises.
