Through Two Doors at Once

The history of quantum physics as detailed through the many theoretical and experimental iterations of the double slit experiment (the Mach-Zehnder interferometer being the easier to grasp and easier to replicate cousin). Non-locality, spooky action at a distance, collapse of the wave equation, quantum erasers, many-worlds. The fascinating question at the bottom of the nature of reality - the wave particle duality. Splitting the physics community in two camps. Are you a realist or a non-realist?

Great read, very lucid and concise, I could follow most of the physics (most, not all).
