Hi, I'm David Mackintosh, a professional engineering physicist, who has worked for 20+ years in the field of nondestructive testing (NDT). I live in western Canada where I work for a major NDT company. I have a Master's degree in Engineering Physics and a B.A. in History. My writing interests outside of engineering, science, and NDT include history, spirituality, and book reviews.
