Ok, not all of quantum physics. Mainly just the Double Slit Experiment or Wavefunctions in general. You only have 3 sentences to teach either one (or both) to an idiot (not me) and they can't be run on sentences either. This also has to be a math free explanation. It's not so much a challenge of simplifying the ideas to their most succinct states as it is choosing what is important to know and what you don't really need to know. Kindof like the desert island deal. If you could only take three facts about quantum physics with you, what would they be?
