Man, I’d love to get this pocket cipher machine at the upcoming Sotheby’s “History of Science and Technology” auction. (It’s $3,500, though.) Using an algorithm to co-write a sci-fi short story. How Linneas invented the index card (and thus, ultimately, the database). A book on the science of jellyfish (which, under global warming, may wind up ruling the planet). They may have found the bones of the original Saint Nicholas. LED traffic lights are so energy-efficient they don’t emit enough heat to melt the snow that gathers on them. Wow, when Time picked the computer as “Machine of the Year” in 1983, the cover illustration was creepy. Some proof that lightning creates antimatter.
