The Law of Causality and its Limits was the principal philosophical work of the physicist turned philosopher, Philipp Frank. Born in Vienna on March 20, 1884, Frank died in Cambridge, Massachusetts on July 21, 1966. He received his doctorate in 1907 at the University of Vienna in theoretical physics, having studied under Ludwig Boltzmann; his sub sequent research in physics and mathematics was represented by more than 60 scientific papers. Moreover his great success as teacher and expositor was recognized throughout the scientific world with publication of his collaborative Die Differentialgleichungen der Mechanik und Physik, with Richard von Mises, in 1925-27. Frank was responsible for the second volume, on physics, and especially noted for his authoritative article on classical Hamiltonian mechanics and optics. Among his earliest papers were those, beginning in 1908, devoted to special relativity, which together with general relativity and physical cosmology occupied him throughout his life. Already in 1907, Frank published his seminal paper 'Kausalgesetz und Erfahrung' ('Experience and the Law of Causality'), much later collected with a splendid selection of his essays on philosophy of science, in English (1941c and 1949g, in our Bibliography). Joining the first 'Vienna Circle' in the first decade of the 20th century, with Hans Hahn, mathematician, and Otto Neurath, sociologist and economist, and deeply influenced by studies of Ernst Mach's critical conceptual histories of science and by the striking challenge of Poincare and Duhem, Frank continued his epistemological investigations."

Caveolae (latin for little caves) are small structures found at the surface of cells. They are responsible for the regulation of important metabolic pathway. As a consequence, they may play a critical role in several human diseases such as atherosclerosis, cancer, diabetes, and muscular dystrophies. This book analyzes the role and function of caveolae in these aspects and serves as the first textbook currently available on caveolae/caveolin.

Das Manuskript zu diesem Buch ist unter merkwurdigen Um standen entstanden. Ich begann die Niederschrift 1939 in New York, setzte sie 1940 in Chicago fort und beendete den grossten Teil 1941 in Boston. Das Manuskript war in deutscher Sprache geschrieben, aber begreiflicherweise unter der damaligen Reichs regierung nicht fur eine Veroffentlichung in deutscher Sprache bestimmt; 'es sollte ins Englische ubersetzt und in Amerika ver offentlicht werden. Bevor die ubersetzung beendet war, wurde die Einsteinsche Relativitatstheorie, die oft als eine spekulative Hypothese an gesehen und unterschatzt wurde, die Grundlage einer ganz neuen Wendung in der technischen Entwicklung der Menschheit: Die Kernenergie des Atoms wurde die Energiequelle der Zukunft, und all die truben Prophezeiungen uber ein Versagen der Energie quellen konnten zum alten Gerumpel geworfen werden. Jm Jahre 1945 fugte ich eine Darstellung dieser Wendung in englischer Sprache hinzu, und dieser Teil ist der einzige im Buch, der aus dem Englischen ubersetzt ist. Die amerikanische Ausgabe erschien 1947; grosse Teile der deutschen Fassung wurden nicht aufgenom men. Daher ist das vorliegende Buch die erste vollstandige Wieder gabe meines Manuskriptes."

Seit beinahe einem Jahrhundert sind Mathematiker und Logiker mit Erfolg bemuht, aus der Logik eine strenge Wissen. schaft zu machen. Dieses Ziel ist in einem gewissen Sinn erreicht worden: man hat gelernt, in der Logistik mit Symbolen und Formeln ahnlich denen der Mathematik in strenger Weise zu operieren. Aber ein logisches Buch muss ausser den Formeln auch Zwischentext enthalten, der mit Hilfe der gewohnlichen Wort. sprache uber die Formeln spricht und ihren Zusammenhang klar macht. Dieser Zwischentext lasst oft an Klarheit und Exakt. heit manches zu wunschen ubrig. In den letzten Jahren nun hat sich bei den Logikern verschiedener Richtungen immer mehr die Einsicht entwickelt, dass dieser Zwischentext das Wesentliche an der Logik ist und dass es darauf ankommt, fur diese Satze uber Satze eine exakte Methode zu entwickeln. Dieses Buch will die systematische Darstellung einer solchen Methode, der "logischen Syntax," geben (nahere Erlauterungen in der Einleitung, 1, 2). In unserem "Wiener Kreis" und in manchen ahnlich gerich. teten Gruppen (in Polen, Frankreich, England, USA. und ver. einzelt sogar in Deutschland) hat sich gegenwartig die Auffassung immer deutlicher herausgebildet, dass die traditionelle meta. physische Philosophie keinen Anspruch auf Wissenschaftlichkeit machen kann. Was an der Arbeit des Philosophen wissenschaft. lich haltbar ist, besteht - soweit es nicht empirische Fragen betrifft, die der Realwissenschaft zuzuweisen sind - in logischer Analyse. Die logische Syntax will nun ein Begriffsgebaude, eine Sprache liefern, mit deren Hilfe die Ergebnisse logischer Analyse exakt formulierbar sind. Philosophie wird durch Wissen."

Much has been written about Albert Einstein, technical and biographical, but very little remains as valuable as this unique hybrid of a book written by Einstein's colleague and contemporary. Both rich in personal insights and grounded in a deep knowledge of twentieth-century science, Phillip Frank's biography anchors the reader with a lucid overview of physics and draws an intimate portrait of the Nobel Prize-winner.
