The Infinite Corridor is MIT’s spinal cord. Many of our departments, classrooms, and labs radiate from here. Whatever you do, stay to the right when traveling the corridor and note that pedestrian speed increases dramatically when classes let out.
In mid-November and in late January every year, the circular path of the sun crosses the axis of the Infinite Corridor. (As viewed from a stationary point on the earth, the path of the sun through the sky is roughly a circle that moves north and south as the seasons go by.) When this happens, the setting sun can be seen from the far end of the corridor. This particular moment is sometimes called MIThenge, a reference to Stonehenge.
