What I Believe: Bull Durham Style (1988) [CC] Kathy Loves Physics & History 2023-11-10 | This video is a bit different. It is about what I love, based on many 1980s movies that inspired me including: "Ferris Bueler's Day Off," "Real Genius," "It's Never Better Off Dead" and more. By the way, the part of the video with the popcorn is from "Real Genius" and the song "Everybody Wants to Rule the World" is about climate change.I hope you enjoy this little video as much as I did in making it. Cheers,Kathy Loves Physicsps. I didn't add commercials so I can use clips without reference. Also, originally, I complained about Richard Feynmann, but I realized it came off as mean, so that is why so many people are talking about him in the comments.

If you put a tube with a balloon on top of the leads you can collect the gas but be careful, the gasses can be dangerous around a flame!Thanks:Big Shout out to Bertrand Wolff in France who is working with Christine Blondel on the History of Electricity. Their videos have a lot more detail on how to recreate the experiments (and how to dissect the frog). If you speak any French I recommend you check it out! The frog videos were made at their request by Dr. Francois Ferriere at the University de Rennes 1 and can be seen at:http://www.ampere.cnrs.fr/histoire/items/show/343The videos of the voltage and maximum current from a voltaic pile as well as the gentleman getting shocked can be seen at:http://www.ampere.cnrs.fr/parcourspedagogique/zoom/video/piledevolta/video/
Bohr model: Math and Logic of Derivation Kathy Loves Physics & History 2020-09-04 | This is a detailed derivation of Bohr's model to get to the Balmer series and Rydberg's constant from fundamental principles. It is at AP Physics/Freshman College Level.

Bohr Model: A Delightful History [CC] Kathy Loves Physics & History 2020-08-16 | How did 27-yr-old Niels Bohr make a model of the atom that was so audacious even Einstein admitted it he did not dare publish them? This is a story of dorky physics jokes, a truly supportive marriage, a useful conversation and a brilliant maid. Ready?

Heisenberg, Bohr: the Friendship behind the Copenhagen Interpretation of Quantum Theory Kathy Loves Physics & History 2020-08-03 | The Copenhagen Interpretation was born of the friendship between Werner Heisenberg and Niels Bohr. How did they meet, how did their friendship change science and how did the outside world damage that friendship?

Heisenberg and Bohrs 1941 Copenhagen Meeting: What Happened? Kathy Loves Physics & History 2020-07-28 | I use letters, secret recordings and diaries to try to solve the mystery of why Heisenberg went to Nazi occupied Denmark and told Bohr that he was working on the military aspects of fission. The answer I came to is depressing about Heisenberg but surprisingly clear. See if you agree with me!My Patreon Page:patreon.com/user?u=15291200Some Links: The clip where Heisenberg is writing Bohr is from a very pro-Heisenberg biography where Heisenberg has a British accent and it is all blamed on Bohr's wife! The link can be found here:youtu.be/K4lY4rF8rQkThe interview of the son of the Rabbi who saved Danish Jews is from a fascinating documentary from the BBC that can be found here:youtu.be/skocUzic4LsThe interview of Edward Teller is from here (and it is interesting to listen to what he thought happened in Copenhagen which was very pro-Heisenberg)youtu.be/ClhLnZtgcsEThe clip where Weizsacker is talking about 1941 is from a fantastic biography that you can find here:youtube.com/watch?v=gGriZxJ6nZQ&t=2sThe song "Electricity, Electricity" is a version of the song originally written by the folks at Schoolhouse Rock by my fabulous friend Kim Nalley.
