| | | | | Today, a friend asked me for help figuring out how to calculate the standard deviation over a discrete probability distribution. I pulled up my notes from college and was able to correctly calculate the standard deviation they had been unable to derive after hours upon hours of searching the internet and trying to piece together poor explanations from questionable sources. The crux of the problem was, as I had suspected, the astonishingly bad notation involved with this particular calculation. | |

| | | | | Despite its simplicity, classical mechanics is not taught well in the typical physics curriculum. This is unfortunate because the general philosophy of constructing Lagrangians based on symmetries underlies all of modern physics. In this article, I explain basic Lagrangian mechanics in a systematic way starting from fundamental physical principles. It basically follows Landau and Lifshitz... | |
