I am a retired Chartered Mechanical Engineer. After working in Aeronautical Engineering, Nuclear Engineering, and Chemical Engineering,I lectured in Mechanical Engineering subjects at Degree Level. My main interests were Heat Transfer, Thermodynamics, and Fluid Mechanics. I also lectured on Dimensional Analysis on a post-graduate course. The current S.I. use of the radian angle conflicts, in my opinion, with the technique of dimensional analysis. I wish to amend the wikipedia article on the Radian in accordance with my article as recently published in an international journal, which fully explains this correction in three pages. The article is "A trigonometrical ratio to replace the dimensionless angle in radians" International Journal of Mechanical Engineering Education" Volume 38, Part 2, April 2010 pages 132,124, and 135.
