It's a book full of classics. My favorite might or might not surprise you. It's the Sherred story, one I've read again and again, and always with pleasure. One of my very favorite time-travel stories. "Blowups Happen" was one of the first (maybe the first) stories about a nuclear reactor, written before such things existed. "Vault of the Beast" is one of those Van Vogt stories that's hard to describe but fun to read, totally implausible, but who cares? Asimov's "Nightfall" is the one about the stars coming out. Tenn's "Child's Play" is about the build-a-man kit. Simak's "Eternity Lost" is about immortality and the serum that provides it -- for a few. You might see the twist ending coming, but I didn't when I first read it. Hey, I was just a kid.
And there's so much more, but there's really no need for me to go on. You probably remember some of these as well or better than I do. Was "Thunder and Roses" the first story to predict the CD? I remember something in there that sure seemed like it, but it's been so long since I read the story that I need to read it again. I might be recalling a different story entirely, or I might have made the whole thing up. Anyway, this is a great anthology, and every story is highly readable and worth reading. It's a classic anthology in the SF field.
