Technology George Ferris's Valentine's Day gift to science teachers

George Ferris, whose 154th birthday is celebrated with a Valentine's Day-themed Google Doodle, didn't just come up with a new amusement park ride; he provided an opportunity for physics teachers to come up with truly terrifying scenarios.

George Ferris, whom Google praises on its home page Thursday, did more than just invent a beloved theme park ride. His eponymous wheel serves as a perfect opportunity for physics teachers to engage in two of their favorite activities: 1) revealing the simple mathematical equations that govern the motions of everything around us, and 2) coming up with horrifying thought experiments.
