I read with interest the following link today:
http://www.bbc.co.uk/news/science-environment-13906169 It describes a constant, Tau, which has twice the value of Pi and it is claimed its usage makes more sense than Pi in a lot of situations and simplifies calculations. Perhaps the GPL version of J could include it as an experimental function: Tau Times.
