"The publication is with out peer in its field." — American Scientist
In this thoroughly revised and enlarged version of a vintage paintings within the background of know-how, a famous pupil explores the significance of technological innovation within the cultural and financial heritage of the West.
Following an introductory dialogue of where of know-how in fiscal heritage, the writer bargains a penetrating historic research of social switch. inside of this context he develops a idea of invention in accordance with Gestalt psychology and an idea of social evolution as non-stop improvement from antiquity to the current. Emphasis is put on the position of monetary forces within the improvement of know-how, with medical suggestions additionally enjoying an immense function in bringing approximately change.
The latter a part of the booklet makes a speciality of the creation and keep an eye on of energy often, and particularly on a few vital operative mechanisms. hence we learn thought-provoking bills of the expertise of fabric manufacture from primitive instances, of water wheels and windmills, water clocks, and mechanical clocks, and the paintings of Leonardo da Vinci. the improvement of printing is punctiliously studied, not just for its intrinsic curiosity, yet as a result of its significance for the background of technology. different themes contain the construction and alertness of strength (1500–1830), desktop instruments and volume construction, the creation and distribution of energy considering that 1832, and the position of Asia Minor as a resource of options which ruled the center a while and the trendy interval as well.
Thoroughly researched and cogently reasoned, A background of Mechanical Inventions belongs within the library of someone attracted to the background of technology and invention, in addition to the connection of know-how to monetary and social history.
"Throughout the ebook there's consistent facts of the author's large studying and sundry highbrow interests." — The long island Times

Fundamentals of the Theory of Plasticity (Dover Books on Engineering)

Meant to be used by means of complex engineering scholars and practising engineers, this quantity makes a speciality of the plastic deformation of metals at general temperatures, as utilized to the power of machines and constructions. It covers difficulties linked to the distinctive nature of plastic nation and demanding functions of plasticity concept.

Bohmian Mechanics and Quantum Theory: An Appraisal

We're usually advised that quantum phenomena call for radical revisions of our medical international view and that no actual thought describing good outlined gadgets, resembling debris defined by means of their positions, evolving in a good outlined method, not to mention deterministically, can account for such phenomena. the good majority of physicists proceed to join this view, even though simply any such deterministic concept, accounting for all the phe­ nomena of nonrelativistic quantum mechanics, used to be proposed through David Bohm greater than 4 a long time in the past and has arguably been round virtually because the inception of quantum mechanics itself.

Computerized Symbolic Manipulation in Mechanics

The purpose of this e-book is to provide very important software program instruments, easy options, tools, and hugely refined purposes of automated symbolic manipulation to mechanics difficulties. an summary approximately general-purpose symbolic software program is through normal directions find out how to improve and enforce top of the range laptop algebra code.

I am also deeply indebted to Mr. Walter B. Briggs for signal assistance at every stage of the work. He has given me helpful guidance in the use of the resources of the library; he has done his utmost to insure the best utilization of its facilities; and he has secured the loan of many scarce volumes from other libraries.

I owe much to my colleagues in the departments of history, the history of science, and economics at the University of Wisconsin for their interest and their suggestions. It was very helpful to concentrate the work of the seminar in economic history on the problems of the theory of invention and historical process. The new chapters owe much to the work in the seminar, and the responses of the students lead me to believe that these problems are not as remote from the underlying problems of historical criticism as they might seem to be.

The great increases in the production of petroleum have been made possible by great increases in the depth of drilling. In the early years, Pennsylvania crudes were obtained at depths that rarely exceeded 300 feet; today large quantities are obtained from wells of more than 8000 feet, and producing wells have been brought in at 15,000 feet. The discovery of new fields has attracted wide attention, but new techniques of recovery are scarcely less important. The deposits of fixed minerals commonly admit of description in terms of the depth of the ores, the width of seams, the approximate concentration of the minerals that are diffused in a matrix.
