Arthur C. Clarke passed away yesterday. 90 years is a wonderfully long time, and apparently his passing was quick and relatively easy. On a personal note, I'm glad I heard about it at a convention dedicated to sf literature, from people who care passionately about the exact types of books Clarke dedicated his life to.
I don't think my life would have been quite the same if I hadn't read Childhood's End and 2010 in middle school. They were both, to me, mind blowing visions of very different futures. I'm glad his books have survived to be enjoyed by many generations of readers.
