In this video, I unbox and discuss a 7th edition CRC handbook of chemistry and physics. In particular, I compare it to a 31st edition copy and a 63rd edition copy, to highlight how much they have changed over the decades.

$Solving The Schrodinger Equation On A Sphere | Quantum Mechanics In this video, I show you how to solve the Schrodinger equation for a particle confined to a 2-sphere space. My Quantum Mechanics Lecture Series: https://www.youtube.com/playlist?list=PLSpklniGdSfSsAFCzO-YWGlJ4TNv8sMdy There is a typo in the spherical harmonics normalization constant. In the second fraction under the square root, the 1s are supposed to be ls.

That formula itself isnt used for anything in the calculation, so this error in no way effects the calculation.$
