Quantum Formalism (video)
I've uploaded my second QM video from my Phil Science class: https://youtu.be/vhSaGazHfSs
TL;DW: I explain in simple form the mathematical formalism used in quantum mechanics, which provides an algorithm for predicting results of experiments. This is crucial to understanding the issues about the interpretation of QM. The formalism is what all interpretations of QM have in common; they give different accounts of what the mathematical objects in the formalism stand for and why the algorithm works. The infamous "Copenhagen interpretation" holds that physical systems are often in indeterminate states with respect to a given property, and that when that property is measured, the system randomly jumps to one of the possible determinate values for that property.
