By Brian Cox, Jeff Forshaw

ISBN-10: 3440149706

ISBN-13: 9783440149706

E = mc² ist die berühmteste Formel der Welt. Mit ihr brachte Einstein es auf den Punkt: Energie und Masse sind zwei Seiten derselben Medaille und die Lichtgeschwindigkeit c ist ihr Wechselkurs. Doch warum besteht dieses so einfache Verhältnis? Wie ist Albert Einstein zu diesem Schluss gekommen? Und welche Folgen für das Verständnis des Universums ergeben sich daraus? Brian Cox, Professor für Physik und in England durch seine Sendungen auf BBC sehr bekannt, hat sich zusammen mit seinem Kollegen Jeff Forshaw, Professor für theoretische Physik, die scheinbar einfache Einstein-Gleichung vorgenommen, um sie mit viel Energie ausführlich und verständlich zu erklären.

Electrochemical Engineering sounds a great deal like chemical engineering, however the chemists, electro chemists, fabric scientists and whoever else comes into contact with technical electrochemical structures very quickly will get the sensation, that chemical engineering knowledge won't get them very a ways in improving their un­ derstanding and assisting them to unravel their issues of technical electro­ chemical units. certainly not just the looks of but in addition the physics and actual chemistry in electrochemical reactors - electrolyzers, batteries or gasoline cells and others - are particularly various from that of standard chemical reactors. subsequent to interfacial cost move and present density distributions is the quite excessive significance of mass move and its obstacle in liquid electrolytes which distinguishes electrolyzers from chemical reactors. for that reason electrochemical engineering technological know-how turned a technology department which at the beginning constructed with little connection with chemical engineering treating the proper themes on a excessive mathe­ maticallevel. This has resulted in a undeniable perfection, which this present day - in principl- permits us to version nearly any wanted electrolyzer or mobilephone configuration with nu­ merical how to a level and precision which satisfies the top calls for. this can be classical chemical engineering stuff, which, notwithstanding, neglects the chem­ ical aspect of electrochemical technology.

Many U.S. readers definitely might be very conversant in the identify of a minimum of one if now not all the technology thoughts mentioned during this volume-for instance, undertaking 2061-and most likely with their normal substance. a lot of the schooling community's familiarity with those arises from the initiatives' personal dissemination efforts. The study stated during this quantity, despite the fact that, is likely one of the few certain experiences of those techniques undertaken by means of researchers open air the initiatives them­ selves. all of the 5 reports was once a large-scale attempt regarding groups of researchers over 3 years. those groups analyzed many records, attended a number of severe undertaking conferences, visited a number of websites, carried out dozens of person interviews. The group leaders (Atkin, Huberman, Rowe), having spent a lot time with technology schooling over lengthy careers, checked out those thoughts via many lenses. It was once a frightening job for every staff to sift during the mountains of element on the way to deliver the main compelling topics to the surface.
