  • 2019.01.08: "I wish there were videos like that when I was going to school. 🙂" Quick Fix - YouTube Comment
Did you know I teach part-time to allow time to make these Flipping Physics videos? That is because it takes a tremendous amount of time to make videos of high caliber. Yep, I am in the classroom 40% of the time of a full-time teacher. That means I make 40% of the salary a full-time teacher. Can you imagine that? So realize, yes, I provide all the videos for free. This is because there are many people on this planet who cannot afford high quality education like this. However, if you can afford to, especially if you are assigning my videos for students to learn from, please pledge me a few dollars a month on Patreon. If not, there are other ways to help out as well. Thanks.
