There are more than a billion mechanical machines in our world of six billion humans. These machines are the source of both marvel and mayhem in the life of our planet. This book is about the evolution of these machines and the inv- tors and engineers who created them from the early Renaissance to the early 20th century. I have chosen two personalities who are icons of these two machine ages, Leonardo da Vinci  1452-1519] and Franz Reuleaux  1829- 1905], recognizing both the cadre of machine designers who in?uenced them as well as those who were in?uenced by the accomplishments of these two engineers. A major thesis of this book is that the evolution of machine design methodology, from the intuitive methods of the workshop to the math-based, engineering science analysis and synthesis of modern industrial design, was of equal achievement as the creation of the marvelous machines themselves. In the past two decades there has been increasing interest in rational me- ods of design from topology and optimization theories to genetic algorithms. In the teaching of design at the novitiate level, the importance of design - cles and iteration is emphasized. Yet often the historical background for e- lution of machine design is minimal or missing.","brand":"WoB","offers":[{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":49889651032337,"sku":"CIN0821980785VG","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ GOOD \/ SBYB","offer_id":49999518499089,"sku":"CIN0821980785G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ WELL_READ \/ SBYB","offer_id":50369939112209,"sku":"CIN0821980785A","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0821980785.jpg?v=1751107029"},{"product_id":"deutsch-aktuell-1-9780821980767-copyright-2017-book-wolfgang-s-kraft-9780821980767","title":"Deutsch Aktuell 1, 9780821980767, Copyright 2017","description":null,"brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50016096452881,"sku":"CIN0821980769G","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ WELL_READ \/ SBYB","offer_id":50097609408785,"sku":"CIN0821980769A","price":0.0,"currency_code":"GBP","in_stock":false},{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51416459215121,"sku":"CIN0821980769VG","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0821980769.jpg?v=1750785874"},{"product_id":"deutsch-aktuell-2-grammar-and-vocabulary-exercises-book-wolfgang-s-kraft-roland-specht-9780821925652","title":"Deutsch Aktuell, 2: Grammar and Vocabulary Exercises","description":"I am very pleased to present a new edition of this book first published in 2005. I have taken the opportunity to include various suggestions and developments in the last ten years. Many new clarinet choirs have been established around the world during this time both in the cultural sector and as training ensembles. This last fact should not however detract from the fact that the clarinet choir as a medium is generally becoming more popular and is emerging as a permanent feature of the concert life in many countries. In the course of giving concerts at home and abroad with my own ensemble, the Austrian Clarinet Choir, I have had the opportunity of getting to know many new arrangements and original works, gaining new inspiration and learning to appreciate the rich possibilities the Clarinet Choir offers. These days, its tonal palette is not only evident to us connoisseurs. In recent times, the public has started to appreciate the scoring of this unique ensemble ranging from the now well-known E flat clarinet down to the Contrabass Clarinet. While I have seen increased interest in the genre in the course of delivering lectures on the subject in Europe, the USA, Latin- and South America, South Africa. it has become apparent that there is hardly any literature on the subject, so it was obviously important to me to have the book translated into English and Spanish and to include as much new information and additional research as I could.","brand":"WoB","offers":[{"title":"US \/ GOOD \/ SBYB","offer_id":50137319801105,"sku":"CIN0821925652G","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0821925652.jpg?v=1750947486"},{"product_id":"deutsch-aktuell-2-annotated-teacher-s-edition-book-wolfgang-s-kraft-9780821954744","title":"Deutsch Aktuell 2, Annotated Teacher's Edition","description":null,"brand":"WoB","offers":[{"title":"US \/ VERY_GOOD \/ SBYB","offer_id":51416501027089,"sku":"CIN0821954741VG","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/0821954741.jpg?v=1750703948"}],"url":"https:\/\/www.worldofbooks.com\/en-gb\/collections\/author-books-by-wolfgang-s-kraft.oembed","provider":"World of Books ","version":"1.0","type":"link"}
