Arrows Across America

I read recently about these huge concrete arrows that were laid out every 10 miles from coast to coast across the USA in 1924. Their purpose: to help guide the postal planes on their long journey. A beacon was also attached to a tower to ensure the arrow's visibility from high altitudes.

An 18th Century Robot

Behold the face of a doll that can write. Built by Jaquet Droz in the mid-1700s, this automaton is programmable with any combination of letters and writes them with a feather and ink.

Meet Marcus Gavius Apicius

Marcus Gavius Apicius was a chef in first-century Rome, who liked to cook up weird and peculiar recipes. There is a cookbook attributed to him, and some of the recipes can be found here - with many sauces dependent on a kind of boiled and reduced wine. It's interesting to look at Roman recipes, but I don't know if I would ever try to make one!
