  • At the beginning of the 19th century the description of matter attained, what one would call today, a scientific basis. Dalton1 supported the atomic theory with experiments permitting the development of modern chemistry. The book “A New System of Chemical Philosophy,” describes this new approach. In Fig. 1.1, an excerpt is displayed. Chapters I and II give a summary of the contemporary understanding of nature by analyzing heat and mass, the two basic building-blocks of any material. Chapter I displays the theory of the caloric as it was generally...

  • ‘Design’ is one of those words that means all things to all people. Every manufactured thing, from the most lyrical of ladies’ hats to the greasiest of gearboxes, qualifies, in some sense or other, as a design. It can mean yet more. Nature, to some is Divine Design; to others it is design by Natural Selection, the ultimate genetic algorithm. The reader will agree that it is necessary to narrow the field, at least a little. This book is about

  • Investigation of the magnetic properties of materials is very important, because magnetic phenomena have various scientific and technical applications. The macroscopic properties of matter are a manifestation of the microscopic properties of the atoms of which it is composed. The magnetic properties of materials may be very different for types of material, depending on their nature and structure.

  • Like most people, you have probably been taught to see money as a tangible resource that resides in your wallet and bank account until you need to spend it. You use it to pay bills, buy products and services, and support worthwhile causes. When you need more money, you probably do what most people would do: take physical action that will bring in more money, such as working extra hours, asking your boss for a raise, or even selling a few of your material possessions.

  • Wet processing of textiles uses large quantities of water, and electrical and thermal energy. Most of these processes involve the use of chemicals as assisting, accelerating or retarding their rates and are carried out at elevated temperatures to transfer mass from processing liquid medium across the surface of textile material in a reasonable time. So, we can use some natural materials and some physical tools to reduce the chemicals, water, energy and pollution.

  • During my career, some 35 years, there has been a growing realization that the goal of successful nuclear waste management and the final disposal of long-lived radionuclides can only be attained by a thorough understanding of the behavior of key, technogenic radionuclides in the environment. Within a nuclear reactor, these radionuclides are created by fission, neutron capture and subsequent beta-decay reactions on actinides, mainly 238 U, and by activation nuclear reactions.

  • Simply put, this book is about how nature is ‘done’, how it is practised, how it materializes as an active partner in and through those practices. Perhaps, unlike many other volumes, I am not especially concerned here with how nature is imagined, represented, thought or conceived. Rather, imagining, representing and thinking are treated as activities which take their place alongside many other practices (like growing, infecting, digging, counting), some of which do not have people at their centre. This last point is crucial.
