If you got dropped off on a random road somewhere on earth, how long before you could figure out where you are?
Try this fun game to find out, without all the bother of mosquitos, the expense of plane fare, or the danger of lurking around strange roads.

How strange is this? For a period of time in 1913 Vienna, Hitler, Stalin, Trotsky, and Franz Ferdinand all lived in the same section of town. Hitler and Trotsky hung out at the same cafe (although I don’t know if they hung out together). Also in town: Sigmund Freud, the founder of psychoanalysis, and Josip Tito, the later communist leader of Yugoslavia.
I had heard that some people dipped their handkerchiefs in the blood of Louis XVI at his execution, but I had no idea that some of the evidence had been saved…
The grossest part of this story, though, in my opinion, is doing experiments with the preserved head of Henry IV!
From the UT San Diego News:
[The US Navy dolphins] patrol for enemy divers. They ping mines and mark the location for handlers. It’s a program that goes back to naval research started in the late 1950s that once included killer whales and sharks.
But now Navy officials say that an unmanned underwater vehicle — a 12-foot torpedo-shaped robot — can do the some of the same mine-hunting jobs. And the machines can be manufactured quickly, unlike the seven years it takes to train a dolphin for duty.
But good news:
But [the Navy spokesman] added that there’s potential to shift these dolphins into a slightly different kind of mine-hunting — the ability to find bombs hidden on the bottom of a body of water.
“About a quarter of (the Navy dolphins) would be affected. But it’s not like they are going to go jobless. We have other assignments,” he said.
