I find that often reading a scientist's dissertation will often tell you something about how they approach the rest of their research. Somewhere I actually have a paper copy of Feynman's Thesis under Wheeler, which covers exactly this material. He was clearly enamored of Lagrangian formulations quite early (I didn't know that it was due to a High School teacher). You can find this actual thesis…

我发现读一个科学家的博士论文往往能让你看出他们后来是怎么做研究的。我手头其实就有一份纸质版的费曼在惠勒指导下的博士论文《Feynman's Thesis》，里面讲的正是这些内容。显然他很早就对拉格朗日表述（Lagrangian formulations）着迷了（我以前都不知道这是受一位高中老师的影响）。你能找到这篇真实的论文…
