Ah well a little late on the ball for the blog, but it is the week end and I was doing other things. Yesterday Nov 7th was the first Carl Sagan Day celebrating what would have been the eponymous scientist's 75th birthday.
Carl Sagan was one of my hero's as a teenager interested in all things scientific. One of the few "big" books that has followed me from house to house and has survived several "clear outs" is "Cosmos" and as my own small part in the celebrations of the day I re-read several of my favourite chapters.
Belated happy birthday Professor Sagan! You are missed!
