Ray Bradbury, the legendary science fiction writer and author of Fahrenheit 451 and The Martian Chronicles, died Wednesday at 91 in Los Angeles. Bradbury's sprawling works are beloved by millions, and he will be remembered as one of the most compelling and influential science fiction writers of the 20th century. In a 2010 interview with The Paris Review, he described what drew him to the genre:
Science fiction is the fiction of ideas. Ideas excite me, and as soon as I get excited, the adrenaline gets going and the next thing I know I'm borrowing energy from the ideas themselves. Science fiction is any idea that occurs in the head and doesn't exist yet, but soon will, and will change everything for everybody, and nothing will ever be the same again. As soon as you have an idea that changes some small part of the world you are writing science fiction. It is always the art of the possible, never the impossible.
