I love classic, hard science fiction (we've talked about the difference between hard and soft science fiction before). Verne, Wells, Asimov: I've read most of what they wrote. These stories, exploring scientifically rigorous possibilities and ideas, hold a unique place in the huge volume of work classified as science fiction. To use the MICE quotient, these are idea stories, through and through. I'd heard about Ringworld in a few different places, and decided that this was something I needed to read.
