I am a generalist with substantial training in both natural and social sciences. From a stint as a military officer, I also acquire the hobby of researching military history, strategies and equipments. My current interests cover technology, politics, economics, finance and science.
Among my contributions to Wikipedia, I am particularly fond of the section I wrote on Kelvin wake pattern. Although the solution to the differential equation is old, this intuitive Geometrical approach is new. Fellow physicists please feel free to comment.
