You deserve a lot more recognition professor Hafner. The most interesting thing about your online courses is that you make them all entertaining no matter the difficulty! We can tell you genuinely enjoy teaching and I hope more students pick up your courses in the future! btw I'm thinking about applying to Rice as a transfer physics student... Might end up in one of ur classes :)

remember a wave is not a thing. it is something a thing does. so, what is the thing?

Hello Professor Hafner, I would like to thank you for taking the time to make these online courses, they are very entertaining and I'm enjoying every detail. I'm currently a PhD student in Biomedical engineering and I would like your suggestion regarding something. I would really like to learn more about exotic matter such as antimatter and maybe "do research with it" if I really enjoy it, but I'm not sure where to start. I'm doing some online courses and think of doing postdocs that gradually take me there. (moving from position to position that use more and more particle physics). What do you think? Are there any resources that you suggest? I would really appreciate your guidance.

“When I was at Rice, my physics profesoras had normal haircuts!” 😂 but is the reverse true- do normal professors have physics haircuts?

Hi Prof Hafner ... You are wonderful professor in physics as I saw few of your earlier videos but I have one doubt that your physics cannot explain one subject in this world not even by the hardest math on earth , shall you take the challenge ?!... OK , here it is , can you please explain the physics of US gov foreign policy ?
