Museum of Math opens in NYC

A door handle in the shape of pi is seen at the new National Museum of Mathematics, in New York City, Dec. 17, 2012. The museum is aimed at kids aged 8 to 13, and curators have given the place a playground feel. The 40 exhibits include a "wall of fire" made up of laser lights that teaches kids about geometry and a square-wheeled tricycle that still manages to produce a smooth ride thanks to a wavy track.
