There Goes the Sun

For a few days each November and January, the setting sun aligns with the axis of the Infinite Corridor and—if the weather coöperates—glints off the hallway’s shiny floors. With the phenomenon known as MIThenge predicted to occur on 11/11/11, about 100 people gathered in Building 8 to watch. The next MIThenge viewing opportunity is expected at 4:50 p.m. on January 28, 2012.
