((vorläufig))In diesem Band werden die wichtigsten Artikel Prandtls zu Turbulenzen und zur Grenzschichttheorie vorgestellt, kommentiert und in einen historischen sowie sozio-kulturellen Hintergrund eingeordnet.

Turbulence is a research field where high expectations have met with recurrent frustration. It is a common perception among physicists, mathematicians and engineers that there is a "big mystery" behind the phenomenon of turbulence. Its history has also remained anything but well researched. Unlike topics such as quantum theory, which began to attract physics historians as long as fifty years ago, turbulence has - until now - received only little professional historical investigation.In this book, which complements his earlier SpringerBrief "The Turbulence Problem", the author sketches the history of turbulence from the vantage point of its roots (Part I), the basic concepts (Part II) and the formation of a scientific community that regarded turbulence as a research field in its own right (Part III). From this perspective turbulence research appears to undertake an odyssey through uncharted territories. The book follows this development up until a conference in Marseille in theyear 1961, which marked the inauguration of turbulence in the words of its organizer as ¿a new science¿. The epilogue contains some observations about turbulence research since 1961. This book provides a rich source of information for all those interested in the history of this major field of basic and applied science.

Dieses Buch liefert eine Sozialgeschichte der modernen theoretischen Physik am Beispiel Arnold Sommerfelds, des nach Einstein einflureichsten und bedeutendsten theoretischen Physikers unseres Jahrhunderts. Der Autor zeigt, da die theoretische Physik sich keineswegs nur durch geniale Ideen zu einer der modernen Wissenschaften des 20. Jahrhunderts entwickelte, sondern auch durch soziale Faktoren wie personliche Anerkennung, missionarischer Eifer beim Verbreiten eigener Ideen, Fortschrittsglauben, wirtschaftliche Randbedingungen, Erwartungen des Staates (Atombombe!), Nationalismus, Erwartungen der Wirtschaft, Wissenschaft als Kulturgut beinflut wurde.

The textbook presents the experiences and techniques of industrial refrigeration and transfers them to commercial refrigeration applications. The general conditions and legal requirements for the use of natural refrigerants, as well as the economic efficiency of the refrigeration systems are also considered and necessary additional knowledge for handling them is imparted. Tables, pictures and plant diagrams are used to show examples of practical implementation.

This book traces the history of Arnold Sommerfeld's famous "nursery of theoretical physics" at the University of Munich and demonstrates the centrality of developing personal and institutional networks for the emergence of quantum theory.

On the road toward a history of turbulence, this book focuses on what the actors in this research field have identified as the "turbulence problem".

Das Schleiermacher-Archiv ist primar ein begleitendes Publikationsorgan fur die seit 1980 erscheinende Gesamtausgabe der Werke Friedrich Schleiermachers (KGA), welches Materialien und Untersuchungen veroffentlicht, die in engerer Beziehung zur KGA stehen. In Sammelbanden werden zudem Beitrage dokumentiert, die auf internationalen Schleiermacher-Kongressen vorgetragen worden oder in diesem Zusammenhang entstanden sind.

This is a comprehensive biography of Ludwig Prandtl (1875-1953), the father of modern aerodynamics. His name is associated most famously with the boundary layer concept, but also with several other topics in 20th century fluid mechanics, particularly turbulence (Prandtl's mixing length). Among his disciples are pioneers of modern fluid mechanics such as Heinrich Blasius, Theodore von Kármán and Walter Tollmien. Furthermore, Prandtl founded the Aerodynamische Versuchsanstalt (AVA) and the Kaiser-Wilhelm-Institut für Strömungsforschung in Göttingen, both of them seeds for the growth of fluid mechanics in Germany. Yet Prandtl was also a representative of aeronautical research - from Imperial Germany via the Weimar Republic to the "Third Reich". Although not a party member, he assumed the role of a goodwill ambassador for Nazi Germany. This objective treatment of his career will be of interest to all scientists and historians wanting to learn more about Prandtl's influence and the early development of fluid- and aerodynamics.

Ludwig Prandtl gilt als Pionier der modernen Stromungsmechanik. Seine Grenzschichttheorie uberbruckte eine Jahrhunderte andauernde Kluft zwischen Theorie und Praxis auf diesem Gebiet. Prandtl hinterlie daruber hinaus bleibende Spuren in einer Fulle von ingenieurwissenschaftlichen Disziplinen, von der Festigkeitslehre bis zur Erforschung der Turbulenz.  Auch beim Aufbau neuer Institute machte sich Ludwig Prandtl einen Namen: Die Aerodynamische Versuchsanstalt in Gottingen, eine Vorlaufer-Einrichtung des Deutschen Zentrums fur Luft- und Raumfahrt (DLR), geht auf Prandtls Initiative zuruck. Zudem grundete er auch das Kaiser- Wilhelm-Institut fur Stromungsforschung, das heute als Max-Planck-Institut fur Dynamik und Selbstorganisation fortbesteht.  Seine Reputation als Vater der modernen Aerodynamik"e; verschaffte Prandtl auch Einfluss bei politischen Weichenstellungen der Luftfahrtforschung - vom Deutschen Kaiserreich uber die Weimarer Republik bis zum Dritten Reich"e;. Im Zweiten Weltkrieg zahlte er zum Kreis der Berater fur die Forschungspolitik des Reichsluftfahrtministeriums. Ludwig Prandtls Korrespondenz mit Kollegen, Forschungsmanagern, Industriellen und Politikern dient dieser Biografie als wichtigste Quelle. Sie ermoglicht einen unverstellten Blick auf die engen Beziehungen zu Technik und Politik, die dieses Wissenschaftlerleben so besonders machten.
