Wave-particle duality, dynamical duality in quantum

One of the issues that was difficult to understand and confusing from the very beginning of quantum mechanics was that we attributed particle properties to entities we knew as waves, and we also attributed wave properties to entities we knew as particles. For example, we considered light to be photon particles and we performed the double-slit experiment for electrons. But what is the story? After all, is the electron a particle or a wave? In this seminar, I want to unpack these experiments a little and relate the wave-particle duality to another duality in quantum mechanics that goes back to the dynamics we have created.
