Sometimes, a picture's worth a thousand words. Sometimes, it's a video clip that's needed to break through the fog of a difficult notion. These clips take on the most challenging concepts that humanity has ever dealt with, and they do so in  a way that makes those concepts seem just a bit more manageable for some folks. These are human issues, not theoretical musings. We did our best to make them relatable, and we hope that you gain a new perspective on the enormous way that they affect your life as a result.
