This is a video of physics, math, astronomy and nature enthusiast Toby 'Tibees' teaching a lesson about logarithms in the style of Bob Ross. Was it effective? Well, before I watched the video I didn't know anything about logarithms since I've forgotten all about them since high school, but now, well *turning canvas around* now I've painted this beautiful landscape. "Are those penises?" You knew what they were! I really am improving.
Keep going for the video.
Thanks to hairless and Stephanie B, who agree everyone learns differently.
