Very relevant to current events. This is a collection of Heinlein’s SF stories, other stories, and articles, beginning with his first SF story in 1939, and including stories & articles through the 1970s. Most have been previously published. In this collection, published in 1980, Heinlein provides a foreword to each story and article, to place them in context, both in terms of personal circumstances, thoughts, and the broader context of science & technology, WWII, and the development and use of catastrophic weapons of war. The underlying themes of science, technology, and war, and how we humans respond to these, make Heinlein's stories and articles timeless, and very relevant to the current times.
