<p>English edition of <i>Kunskap i rörelse</i> (ISBN 978-91-7061-262-6).<br/></p><p>The Royal Swedish Academy Of Sciences in Stockholm has been a knowledge organisation of central importance to Swedish society for almost three centuries. Its institutions and members have gathered data and created new knowledge in laboratories, observatories and the outdoors, sometimes during expeditions to distant lands. However, the Academy has not only produced, but also collected, distributed and popularised knowledge. Through publications, correspondence, meetings, medals and rewards, the Academy has brought together a multitude of different actors researchers, politicians, patrons, engineers, instrument makers and book printers, to name just a few not only in Sweden, but around the world. And, through a continual stream of consultation statements, papers and research policy measures, the Academy has worked to emphasise the value of knowledge and its utilisation.<br/></p><p>In <i>Knowledge in Motion</i>, a dozen Swedish historians of science, medicine and technology depict the long history of the Academy of Sciences. The first section follows the institutional evolution of the Academy, from its founding in 1739 to our own times. This birds-eye perspective vanishes in the second section in which, through almost forty picture essays, we become acquainted with some of the myriad elements that also comprise this history.<br/></p><p>Contribution to the History of the Royal Swedish Academy of Sciences, no. 48 (ISSN 0081-9956). </p>

A colorful look at 3.5 billion years of stromatolites, peculiar structures produced by primitive life forms that lived over vast spans of geologic time. At once diverse, attractive, and sometimes puzzling, fossilized stromatolites are found worldwide in sedimentary rocks-often presenting striking patterns-where they grew in ancient bodies of water that covered parts of the earth billions of years before the dinosaurs. This reference presents a basic, nontechnical account, along with 636 beautiful images of these most ancient of Earthly collectibles. Stromatolites, and the cyanobacteria that produced most of them, were responsible not only for the fossils themselves, but also, more importantly, for the introduction of free oxygen into the planet's atmosphere. Covering a diverse variety of stromatolites and the geologic objects that can resemble them, this book is a delight for stromatophiles as well as those curious about the early Earth.

A new time concept is presented. It concerns the SI unit and quantities for the standard. The physics is analyzed on time. This explication set the fundaments for a new time in most science. I offer clear and simple arguments for most interested readers. The reader reaches the fundaments of contemporary technical time. The application of these theories leads to comprehensively think time in a corrected way. Instead of defining the new time precisely for the standard which is for the responsible to do, the basic ideas around time are formulated, explicated to the new conception easy to apply.
