Clarke's work touches us every day, and not just through fiction. He was one of the developers of actual, working radar systems during the 1940s, and developed the concept of the geosynchronous satellite. If you've talked on a cell phone, you've been touched by his work.
Here in HAL's birthplace, I suspect that this will actually make the local paper. Well, maybe not, as it's spring break. Still, Clarke's work will outlive him, and that's all that any writer can really hope for.
