He is also supposed to thank as many people as he can, in cluding those he is going to confront. In this way he hopes to chain them up to his writing chariot and to forestall their criticism reliably. Since a foreword isa deep-rooted traditionin the pub lishing trade, one must write it, no matter how one feels about it. Yet a conventional foreword, as this author thinks, would be out of place in a book like this. So his choice has been a kind of dialogue in which one side will be hereafter referred to as AUTHOR, and the other side, a person acting on the strength of the publi shing code, will go under the clandestine name of P·UBLISHER. So the PUBLISHER strikes first. P. What sort of book we shall call it according-to the formal classification of literary works? A. To befrank, I find it hard to place my book pre cisely. The point is that it is in two widely differing .. parts. The first is more in the nature of scientific ad vertising, and the second approaches closely popular science, although it has been strongly influenced by 7 J. "science for fun" books now in vogue, like Williams' The Compleat Strategyst and Ya. Khurgin's So What? P. To put it another way, your book does not belong to any (arm of literary work officially established. A. Well, then let's call it popular science. P. What material have you used? A. Mostly periodicals, and some books. P. Whom is the book intended for? A. The "enlightened layman", a man with a good educational background and knowing about the subject matter only what he can learn through the mass media (radio, television, the press, etc.). This book is decidedly for him. And, of course, for school graduates and any one interested in radar. It is not unlikely that radar specialists too will leaf through it. Of course, they will be attracted not so much by the subject-matter as by the drawings made by E. Treskin. They deserve it. P. How should your book be read? The question may sound strange, but there.are books in which the authors suggest the reader read first, say, chapters 1, 2, 4, 7, and 3, then chapter 6, then chapter 1 again. A. The text may be read in normal sequence, and the drawings from beginning to end or the other way round. P. May your book serve as a study aid? A. Positively not, for all the author's effort to present some chapters as they would be in a text-book. In fact, some chapters contain problems for the reader to work out on his own, but nothing will happen if he chooses not to. The succeeding chapters will be easy to un.. derstand anyway. The more elaborate situations are numbered and discussed in that order. The author has made it a point to note both merits and demerits of all the methods and techniques discussed. In this, the au thor has tried to be objective. Still, the book cannot be 8
