Special call out to Michael Benefield, who included the coordinates in his answer, Arwa Ali, who remarked on the beauty of the view from the nearby staircase, and Laleh Cote', who used to take breaks near the Bubble Chamber when she was an intern.

The Bubble Chamber is located outside the entrance to Building 70A. The Bubble Chamber was invented at the Lab by Donald Glaser in 1952. He was awarded the Nobel Prize in Physics in 1960 for his work developing a type of particle detector that became the mainstay of high-energy physics research throughout the 1960s and 1970s.
