Nearly all of this book is taken from an article prepared for a volume of the Encyclopedia of Physics. This article, in turn, is partly based on Dr. Norbert Rosenzweig's translation of an older article on the same subject, written by one of us (H.A.B.) about 25 years ago for the Geiger-Scheel Handbuch der Physik. To the article written last year we have added some Addenda and Errata. These Addenda and Errata refer back to some of the 79 sections of the main text and contain some misprint corrections, additional references and some notes. The aim of this book is two-fold. First, to act as a reference work on calcu lations pertaining to hydrogen-like and helium-like atoms and their comparison with experiments. However, these calculations involve a vast array of approximation methods, mathematical tricks and physical pictures, which are also useful in the application of quantum mechanics to other fields. In many sections we have given more general discussions of the methods and physical ideas than is necessary for the study of the H- and He-atom alone. We hope that this book will thus at least partly fulfill its second aim, namely to be of some use to graduate students who wish to learn "applied quantum mechanics". A basic knowledge of the principles of quantum mechanics, such as given in the early chapters of Schiff's or Bohm's book, is presupposed.

Euclid's Elements is a mathematical and geometric treatise consisting of 13 books attributed to the ancient Greek mathematician Euclid in Alexandria, Ptolemaic Egypt circa 300 BC. It is a collection of definitions, postulates (axioms), propositions (theorems and constructions), and mathematical proofs of the propositions. The books cover Euclidean geometry and the ancient Greek version of elementary number theory. The work also includes an algebraic system that has become known as geometric algebra, which is powerful enough to solve many algebraic problems, including the problem of finding the square root of a number. Elements is the second-oldest extant Greek mathematical treatise after Autolycus' On the Moving Sphere, and it is the oldest extant axiomatic deductive treatment of mathematics. It has proven instrumental in the development of logic and modern science. According to Proclus, the term "element" was used to describe a theorem that is all-pervading and helps furnishing proofs of many other theorems. The word 'element' in the Greek language is the same as 'letter'. This suggests that theorems in the Elements should be seen as standing in the same relation to geometry as letters to language. Later commentators give a slightly different meaning to the term element, emphasizing how the propositions have progressed in small steps, and continued to build on previous propositions in a well-defined order.

Detective Chief Inspector Wilfred Dover is the most idle and avaricious hero in all of crime fiction. Honestly, why should he even be bothered to solve the case? Collected here are eleven unforgettable short stories in the Dover series, from the 1969 story ‘Dover Pulls a Rabbit’, to ‘A Souvenir for Dover’. Editorial reviews: “Something quite out of the ordinary.” Daily Telegraph “Joyce Porter is a joy... Dover is unquestionably the most entertaining detective in fiction.” Guardian “Plotted with the technique of a virtuoso.” New York Times “Wonderfully funny.” Spectator “Dover is wildly, joyously unbelievable; and may he remain so for our comic delight.” Sun “You will be fascinated by his sheer dazzling incompetence. Porter has a keen eye, a wicked sense of comedy, and a delightfully low mind.” Harper’s

In an America broken by a "limited" nuclear war, no one has use for would-be private eye Wally Sands. No one except for Dr. Charles Winfield, an eccentric scientist who believes he was cloned from a prominent biochemist as part of a top-secret project undertaken before the war. Sands sets out to find Winfield's mysterious progenitor, but finds himself on the trail of a killer instead. Now, in far-away, fabled England, Sands must uncover the facts about the case that has brought him to his promised land, and at the same time confront the unsettling truth about his world, his life, and his loyalties. A story of love and betrayal, life and death, the future and the past. A story that will make you laugh, make you cry—and make you think. AWARDS: Philip K.
