User:DaveRusin2

I am the same person as DaveRusin but am unable to recall or change the password on that account, so here I am again. This is the math guy Dave Rusin who spent considerable time employed at Northern Illinois University and the University of Texas, with shorter stints elsewhere. He is also interested in the world at large, and can't stand errors, so I chime in from time to time on completely unrelated Wikipedia pages.
