A middle-aged postal worker by night, I would consider myself an amateur geodesist, strictly dealing with the "direct" and "inverse" problems (both the well known "surface conforming", as well as the geographically delineated, found using the transverse meridional radius of curvature), with a particular interest in arcradius and its ellipsoidal mean. My formal math education is only through high school Algebra 2 (when I started looking for distance formula--over 20 years ago--I had no clue as to the difference between orthodromic and loxodromic distance, or even how to convert between sine and cosine, let alone what an integral was! P=), but have since become quite proficient with trigonometric functions and relationships, as well as a fair to good understanding of numerical calculus and distance related elliptic integrals. I have been a <a href="">registered contributor to WikiPedia</a> since October 2005.
