Writing technical material in an informative manner for the layman is an art that few of us possess. It requires both a thorough understanding of science and an ability to express it in terms that are at once accurate and interesting. Many of the so-called popularizers of science today fail, in my opinion, because they sacrifice accuracy to provide an exotic impact. One of the early attempts to present science in meaningful terms for the layman (and possibly still one of the best ever) was Leonhard Euler (1707 to 1783). His Letters to a German Princess are masterpieces of scientific exposition.
