Following on from Ted Harding's piece on Buffon's Needle, I offer a piece (produced using groff) of my own which will be published in *The Palgrave Encyclopædia of Strategic Management,* edited by David Teece and Mie Augier, (London: Palgrave, 2014), at http://www.agsm.edu.au/bobm/papers/MonteCarloPESM-longer.pdf
I use groff to produce _all_ my lecture notes, papers (except those stipulated to be in LaTex), letters, etc. See the lot at http://www.agsm.edu.au/bobm/ I definitely lean towards Peter rather than Eric in my use of groff to produce PDFs, even when I proceed to put them up on the web, embedded in simple HTML pages.
