He took the illusion that time was universal, a concept dating back, essentially, to Galileo and Newton, and shattered it, both within and without the scientific community. \u003c\/p\u003e\n\n\u003cp\u003eThermodynamics teaches us that time has a preferential direction, i.e., forward, and is irreversible, as shown by Prigogine and his theories on dissipative structures and complex systems. Time is not only an “external spectator” to what happens, but assiduously takes part in making it happen. \u003c\/p\u003e\n\nThe concept of thermodynamics shows us how time is linked with environmental issues, as creator and destroyer. The author explores the relationships of cause and effect and how it can help in measuring the various eras of the planet, as wellas understanding the beings that inhabit it. \n\n\u003cp\u003eThis book will be a valuable read for students, researchers, and interested laypersons alike.\u003c\/p\u003e\u003cp\u003e\u003c\/p\u003e","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52338457116945,"sku":"NLS9783030943714","price":0.0,"currency_code":"GBP","in_stock":true},{"title":"US \/ NEW \/ INGRAM","offer_id":53015389536529,"sku":"NIN9783030943714","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783030943714.jpg?v=1789125979"},{"product_id":"heat-pumps-book-walter-grassi-9783319872551","title":"Heat Pumps","description":"\u003cp\u003eThe text describes the main features of currently available heat pumps, focusing on system operation and interactions with external heat sources. In fact, before choosing a heat pump, several aspects must be assessed in detail: the actual climate of the installation site, the building’s energy requirements, the heating system, the type of operation etc. After discussing the general working principles, the book describes the main components of compression machines – for EHPs, GHPs and CO2 heat pumps. It then addresses absorption heat pumps and provides additional details on the behavior of two-fluid mixtures. The book presents a performance comparison for the different types, helping designers choose the right one for their needs, and discusses the main refrigerants. Notes on helpful additional literature, websites and videos, also concerning relevant European regulations, round out the coverage. This book will be of interest to all engineers and technicians whose work involves heatpumps. It will also benefit students in energy engineering degree programs who want to deepen their understanding of heat pumps.\u003c\/p\u003e","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":52418490827025,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":52418491580689,"sku":"NGR9783319872551","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783319872551.jpg?v=1786050726"},{"product_id":"heat-pumps-book-walter-grassi-9783319621982","title":"Heat Pumps","description":"The text describes the main features of currently available heat pumps, focusing on system operation and interactions with external heat sources.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ INGRAM","offer_id":52472060772625,"sku":"NLS9783319621982","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0784\/4072\/6801\/files\/9783319621982.jpg?v=1786700468"}],"url":"https:\/\/www.worldofbooks.com\/collections\/author-books-by-walter-grassi.oembed","provider":"World of Books ","version":"1.0","type":"link"}
