J. Robert Oppenheimer forever changed the course of history. He may be the most important physicist to have ever lived. Part of this video is sponsored by Wren.

If you want to learn more about Oppenheimer, I strongly recommend the book “American Prometheus” By Kai Bird and Martin Sherwin. It was the inspiration for Christopher Nolan's 2023 film "Oppenheimer", which won multiple awards, including Oscars in 2024 for Best Picture and Best Actor (Cillian Murphy). If you’re looking for a molecular modeling kit, try Snatoms – a kit I invented where the atoms snap together magnetically – null ▀▀▀ A huge thank you to Dr. Martin Rohde and Dr. Antonia Denkova from the TU Delft for proofreading the script and providing valuable feedback. ▀▀▀ References: Bird, K., & Sherwin, M.
