I can answer most questions involving general science and engineering, except those involving electronics and computers.  My strong points are all the Earth Sciences, especially Meteorology and Astronomy, and any related subjects to Astronomy.  My weak point is Electronics Technology.   No astrology questions please, or questions about alleged UFO identifications.
