I'll quote the story, since you don't want to google it: >> While Overholser himself described Ufimtsev’s work as, “so obtuse and impenetrable that only a nerd’s nerd would have waded through it,” he quickly recognized that a creative interpretation of the book could offer a means by which one could calculate how electromagnetic energy would reflect off of a two-dimensional shape. Overholser then reasoned that if they could break down the design of an aircraft into a collection of two-dimensional triangles, it could be possible to calculate an aircraft’s complete radar return without having to actually build it and stick it in front of a radar array for testing like Boeing’s Quiet Bird. << It was a book, not a journal paper apparently.
