A guide to building simple oscillating steam engine models. It describes the making of four such models: Kitty, a small overtype engine; Otto, a simple steam turbine plant; Wencelas, a superior Christmas present; and Henry a 19th-century vertical engine and boiler.

This practical, instructional book describes the construction of a model of the Lampitt portable steam engine, which dates back to 1862, and which provided rotative power to drive threshing machines, circular saws, feed mills and other farm machinery. The construction of every component is described in precise detail and the text is supported by many helpful step-by-step photographs. In addition, useful advice is provided about obtaining materials and about the tools that are required to equip a model-engineering workshop. Accordingly, the information provided in this fascinating book will enable the reader to construct not only the Lampitt engine but also many other engineering models in the future. When the reader has finished building 'the Lampitt' he will, in effect, have completed an engineering apprenticeship, and will have a model engine of which he can be proud and which fully reveals the skills that he has learned. Fully illustrated with 142 step-by-step colour photographs.

In tbis splendid collection of the articles and addresses of P. L. Kapitza, the author remarks on the insight of the 18th century Ukrainian philosopher Skovoroda who wrote: "We must be grateful to God that He created the world in such a way that everytbing simple is true, and everything compli cated is untrue. " At another place, Kapitza meditates on the roles played by instinct, imagination, audacity, experiment, and hard work in the develop ment of science, and for a moment seems to despair at understanding the dogged arguments of great scientists: "Einstein loved to refer to God when there was no more sensible argument!" With Academician Kapitza, there are reasoned arguments, plausible alter natives, humor and humane discipline, energy and patience, a skill for the practical, and transcendent clarity about what is at issue in theoretical practice as in engineering necessities. Kapitza has been physicist, engineer, research manager, teacher, humanist, and tbis book demonstrates that he is a wise interpreter of historical, philosophical, and social realities. He is also, in C. P. Snow's words, strong, brave, and good (Variety of Men, N. Y. 1966, p. 19). In this preface, we shall point to themes from Kapitza's interpretations of science and life. On scientific work. Good work is never done with someone else's hands. The separation of theory from experience, from experimental work, and from practice, above all harms theory itself.
