I'm not sure if this has been linked on this forum or not, but Sanjoy
Mahajan wrote a neat book on estimation in physics and mathematical problem
solving called Street-Fighting Mathematics: The art of Educated Guessing and
Opportunistic Problem Solving.  It is free in PDF form online, and chapter 3
looks, among other things, at analyzing a pendulum with non-small
oscillations.  Here's the link for those interested:
