I honestly don’t write comments, but man it really does take some serious genius-like skills to be able to teach the way you do. I’ve been struggling to piece it all together, remembering learning bits and bits over the years. Now, I feel like my mind is finally at peace. I wish you taught at my school 😭

[@mangographieellen]

I wish my professors had just one percent of enthusiasm for their teaching. they're probably into whatever they're researching, but they don't give a shit about how amazing all of this is for someone who is just learning about it, but no matter how well you know your stuff, you never fail to infect me with your enthusiasm. whenever I have a new incompetent professor I come to your channel to find my passion for what I'm studying again and I can't thank you enough for what you do.

[@bephey3296]

As a professor I enjoy your videos. They help me to focus in on the most important concepts so that I can be more engaging with my students.
