Add to the history of ghost hunting by trying the latest technology 

The beauty in ghost-hunting is its simplicity — and the wide availability of the technology it relies on. Take the case of the temperature gun: on a dark, cold night in the spring of 2019, I paraded around campus with a group of students from my Campus Sustainability course. Our mission was to identify buildings on campus that leaked heat due to insufficient insulation. In the tiny window of the temperature gun, we observed spine-chilling temperature changes around window frames and in the mortar between bricks where heat was escaping. The lack of energy efficiency in the College’s ancient buildings was not paranormal, but it certainly gave us a fright. With some extra time and the power of scientific discovery in our hands, we visited the famed “ghost room” on the fourth floor of Wilder Hall.
