【On the 'elegance' of the de Broglie model】 In the video, the standing wave of an electron is represented as a sine function that fluctuates along a circular orbit, but that is quite different from the actual appearance of an electron. The three-dimensional wave called 'orbital' that comes out by solving the Schrödinger equation represents the actual electron wave much more accurately. However, the process of solving the partial differential equation using numerous special functions does not feel very 'elegant'. Although the de Broglie model is not the final model, the reason it accurately explains the spectrum of hydrogen atoms is because it contains the necessary core. The fact that one simple idea contains such an accurate core feels very elegant, like French art soccer that removes a solid defensive line with minimal movement or Picasso's drawing that creates a masterpiece by roughly drawing with a blunt brush. 【Learning Quantum Mechanics with a Wine Glass】 ⟪Learning Quantum Mechanics with a Wine Glass⟫ is a 1-hour long feature-length science documentary and can be found on DMT PARK's personal lecture platform: https://dmtpark.teachable.com/p/glass 【thanks to】 Special thanks to Ji-Un, DongggyeolTV, BERTZ, Deokchun, Hyun-Woong Kim, Hyungdo Ryu, physics, Myungsoo Jung, 72, Seokhyeon Kim, Woochanghwa, GGGO, Ruya Young, TaehwanHong, Jang Jiwoong, and Jungmi Lee for their support through 'Super Thanks'.
