I'm from Turkey and physics teachers here are nothing compared to you. You saved my life and made me to like physics more. Because you talked about stories behind every incidents. And this just impressed me so much. I admire your work and thank you for effort.

Most aren’t mate, all my physics teachers have been ass, but man this guy can teacher, he explains it so damn well

Considering your incorrect grammar (hinting at your capability to understand your lessons in English) and the fact that we have many great physicists, talk for yourself and your own school :(

I was looking for some alternate sources for my physics class, and I came across these videos. Dr Anderson, you were one of the best teachers I have ever had. I remember failing your class, and I felt so incredibly bad about it. It probably (hopefully not) happens a lot, and I'm sure it wasn't a big deal to you, but it was a big deal to me. I felt like I personally let you down, and had trouble looking you in the eye after that. You seemed very understanding, though. I took your class again, tried very hard, and finally passed! I want to say that it was your class, that after 14-16 years of schooling, that finally taught me the value of studying and homework. On a side note, I am a physics teacher in high school now, and your class and teaching style are definitely one of my biggest inspirations and influences. I probably spend far too much time on E&M, but it's now one of my favorite topics. Thank you for all of your dedication and hard work!

[@yoprofmatt]

Ryan, Great to hear from you! And thanks for the kind words. They have made my day. Send me an email so we can catch up. Some of your classmates are also HS teachers now. We should get everyone connected. Cheers, Dr. A

I have watched the video for 12 minutes. There are four mistakes: The arrow of rays should be in the middle on the straight line, the metal surface of a mirror is behind the glass, the laws of refection must include the incident ray, the reflected ray and the normal lie on the same plane, and the image of mirror should be written in dotted line.

[@ibanix2]

I love these series, though I have to make a small comment about 3:30 or so.... "left the star millions of years ago". Well... the photon might have bounced around inside the sun for millions of years (more like 100k years), but it didn't leave the sun until about 8 minutes before you see it!
