What Should Non-Scientists Learn From Physics?
This is, of course, a difficult question to answer as an academic, because as somebody who's spent the last twenty-mumble years making a living doing physics, there's an enormous list of specific physics content that I find important and useful. There's a wealth of material just in classical physics that would be helpful for everyone to know. Newton's Laws of mechanics, and the follow-on ideas of energy, momentum, and angular momentum conservation are extremely useful for understanding what goes on in any number of everyday situations, which can enrich your life even if you don't get any practical use out of it-- I regularly plug Rhett Allain's blogging for Wired, for example, and his video analyses are an excellent example of this. You're probably not actually going to do any of the tricks and stunts he breaks down, but it's fun knowing how those things work all the same.
