What Schrödinger’s cat REALLY means

As a professional physics educator (with a PhD in physics education no less) I've been explaining this for years to different people (including a general audience for an event at a science festival). My approach is usually along the lines of "Here's what we know for sure, because we've run the experiments. Here's the math that explains it PERFECTLY (up to the levels of precision we've achieved, which are insane). Here are some interpretations of this math and why they are weird. It's weird y'all!"
