A few summers ago, I had the pleasure of working at Fermilab on the Holometer Experiment. I wrote a series of posts attempting to explain the experiment. In my AP Physics B class, we take a day after finishing nuclear physics to share my experience with my students. The Holometer and the physics behind it are a great example of how much we don’t yet understand about our universe. I want students to appreciate that the field of physics is constantly changing and there is so much more to explore. Too often an introductory physics course presents the material in the context of 100-year-old, dead, white guys.
