Fantasy and Science Fiction
I've dipped my toe into the Coursera course of title above. Perhaps I'm not really into the spirit of the thing. Coursera gives one the option of listening to the lectures at normal speed, 0.75 speed, 1.25, 1.5, 1.75 or 2.0. I can't really follow very well at the highest speeds, but I did notice that when the prof was explaining to us that it was crucial to read the stories slowly, I was watching him at 1.5 speed.
