- 2018.01.16: "Thank you for making these videos. I'm new to not only AP Physics, but physics in general. After utterly failing physics in college, I swore off ever teaching it. Now, as the resident chemistry teacher, I'm teaching a 15 person AP Physics 1 course. I was in over my head until I found your videos. The kids LOVE THEM! If I assign them videos that aren't Flipping Physics, they get upset. Seriously, your videos have saved my class. Thank you for all you do!!!" Linda Detwiler - Patreon Comment
