Subject: tutorial on pendulum theory

I've written a paper titled "A tutorial on gravitational pendulum theory
applied to seismic sensing of translation and rotation" for a special
edition of the Bull. Seism. Soc. Amer. concerned with rotation,
technical editor Willie Lee.  I don't know if it is too technical for
the majority of folks but figured I would let you know about it anyway.
The paper has been posted to my webpage at
The request for me to generate this paper originated with John Lahr's
mentioning my research to Willie, with whom John worked for a long time
(before he retired from the USGS).  Without John's passionate
involvement with amateur seismology and science education (reason I came
to know him) none of this would have happened.
