One of the most tragic events in the history of space exploration is the loss of the space shuttle Columbia and all seven of its crew on February 1, 2003—a tragedy made worse because it didn’t have to happen. But just as it is human nature to look to the future and wonder what might be, so too is it in our nature to look at the past and wonder, “what if?” Today, 13 years after the event, Ars is rerunning our detailed 2014 examination of the biggest Columbia “what if” of all—what if NASA had recognized the danger?

The AK-47, one of the most widely used assault rifles on the planet, has a reputation for being a cinch to make and practically impossible to break.
The demi began when a visitor from France told Zibeau and friends about two alternative currencies circulating in his hometown of Nantes, alongside the Euro. They got to talking about the ins and outs of alternative bank notes, particularly the security aspect. “We joked about [how] the Canadian dollar is pretty secure,” says Zibeau.
