By concisely and comedically describing Dark Matter, or "Unexplained Gravity" as he called it during his 3 minute time farm, Bogdan successfully qualified for the finals of FameLab. Congrats Bogdan! He was able to think well on his feet by answering questions and was even able to bring up WIMPs. Awesome job. Enjoy his speech and wish him luck in the finals on Thursday, which you can see live, hopefully even with audio (unlike the 1st semi-final.)
Yep, I make physics videos in the hope that you can learn physics. If you are a physics teacher, I am very hopeful that you will want to use them to help flip your physics class.
