Arthur C. Clarke has died. He was one of my favourite writers when I was a teenager, and had the great strength that most of his science made sense - he was for a long time more of a visionary populariser of science who could write than an author who liked science.
He'll pretty much always be credited with inventing the communications satellite. Actually, as I remember, he just popularised the idea which was already hiding in some obscure scientific literature.
He probably stands out to me as someone who was excellent at popularising and motivating people to love physics. He'll be missed.
