Tuesday Thought: <i>pi</i> equals 3.14, but maybe 1 doesn't equal 1...

I don’t remember a lot from my high school Physics class, but I do remember liking a lot of it. I’m one of those people that when it comes to specific recollection can struggle quite a lot, but then has moments of perfect recall for no apparent reason. So despite my enjoyment, much of the field of physics is completely forgotten to me. For people in my scenario, some of the things you are most likely to remember are useful and simple formulae and constants. For example (of the top of my head): pi = 3.14 Force exerted by gravity on Earth (g) = 9.8 m/s^2 Force = Mass X Acceleration Kinetic Energy = 0.5(mv^2) Potential Energy from gravity = mass X g X height from surface And that’s about it, right now. Not so great, I’m sure I could come up with more, with time. Something else though… everything [continue]
