Talks on this subject were given in November 1997 at
Illinois Wesleyan University (Bloomington IL), Truman State University (Kirksville MO),
and at the Illinois-Section American Association of Physics Teachers (AAPT) Meeting as well.
Nano-exploration is also the topic of a talk for AAPT Winter 1998 in New Orleans (one of three).
