John!  

Since you wrote numerical methods, I, of course, thought of leapfrog or Euler, or Verlet.  

Especially as a coincidence that must happen.  The local advertiser has an article by a journalist writing about his experience sky diving, so I’m writing a letter to the editors “educating “ the readers about the simple numerical method for obtaining the terminal speed.  My intro to this numerical method (previous cent.) was from Eisberg’s intro physics book, wherein he uses numerical through out.  Curiously he writes that assuming the drag is proportional to v^3 it is not possible to find analytically.  He does give as a check the analytical formula for v^2.  


bc ….  thinks unlikely JD’s method.
