Story of how Planck discovered the blackbody radiation formula and why he introduced energy quantization as a math trick

Errata:
08:10 instead of Pringscheim should be Pringsheim, thanks to ‪@petermarksteiner7754‬ for notifying this
14:40 after the integration there is an extra minus sign that should not be there, thanks ‪@escandestone6001‬ for notifying this
20:22 second equation should be ε/(kT)=log(1+ε/U), thanks to ‪@Galileosays‬ for notifying this
23:52 "gasses" should be "gases," thanks to ‪@robert-skibelo‬ for notifying this
