Reflexivity is a category that is too appealing not to arouse interest. It is a concept largely diffused in several psychological domains, as well as associated with epistemological, theoretical, methodological and practical discussions. At the same time, it is a very polysemic notion, understood and used in many different ways. If one approaches the notion and tries to identify the semantic boundaries of its usage, the seeming solidity of the term fades away, and a rather liquid semantic field emerges - a field where several interpretations coexist, being contingent to the context of the discussion in which they are implemented. This is the reason that makes the notion of reflexivity a prototypical example of the difficulties encountered by Psychology - and more in general social sciences -in the effort to define their own language. The term "reflexivity" ? like many others the language of Psychology is full of - is used in daily life and thus its semantics is shaped by the pragmatic, contingent functions it serves in such communicational circumstances. The apparent - from afar ? clearness of the concept does not concern its conceptual, epistemic status, but the capacity of the sign to contribute efficaciously to mediate and regulate the exchange. The theoretical elaboration of the notion of reflexivity can be seen as one of the ways of performing the challenging task of developing an intentional language for Psychology. By working on such a notion one can realize that common sense lies at the core of psychological science and what it means to separate the former from the latter, so as to pursue the foundational task of developing Psychology as a theory?driven science.

A concise, uncluttered edition for the modern reader, with a new introduction. Quantum Theory contains two foundational works of quantum research from the early years of the 20th Century, representing breakthroughs in science that radically altered the landscape of modern knowledge: Quantum Theory of Line-Spectra by Niels Bohr and The Origin and Development of the Quantum Theory by Max Planck. The FLAME TREE Foundations series features core publications which together have shaped the cultural landscape of the modern world, with cutting-edge research distilled into pocket guides designed to be both accessible and informative.

Niels Bohr (1885-1962) was a Danish physicist who played a key role in the development of atomic theory and quantum mechanics, he was awarded the Nobel Prize for Physics in 1922. First published in 1924, this concise volume provides an English translation of a 1923 German language essay which appeared in the Zeitschrift fur Physik journal. It concerns itself with the fundamental postulates of quantum theory, aiming to present the principles of the theory in such a way that their application appears free from contradiction. This book will be of value to anyone with an interest in Bohr's contribution to physics.

Niels Bohr (1885 1962) was a Danish physicist who played a key role in the development of atomic theory and quantum mechanics, he was awarded the Nobel Prize for Physics in 1922. First published in 1924, this second edition of a 1922 original contains three essays by Bohr dealing with the application of quantum theory to problems of atomic structure: the first essay is on the spectrum of hydrogen; the second is on the series spectra of the elements; the third is on the structure of the atom and the physical and chemical properties of the elements. The essays do not aim at a comprehensive treatment of their subjects, instead providing the reader with a more accessible, generalised viewpoint. This book will be of value to anyone with an interest in Bohr's contribution to physics.

Niels Bohr (1885-1962) was a Danish physicist who played a key role in the development of atomic theory and quantum mechanics, he was awarded the Nobel Prize for Physics in 1922. First published in 1934, and reprinted in 1961, this collection contains four articles and an introductory survey. Originally written for various journals during the 1920s, the articles concern themselves with the epistemological significance of discoveries in quantum physics. Although aimed at physicists, they are generally non-technical, with only one using some elementary mathematics. This book will be of value to anyone with an interest in Bohr's contribution to physics.

Als ich von verschiedenen Seiten aufgefordert wurde, die nach folgenden, vor einigen Jahren in den "Naturwissenschaften" erschienenen Artikel gesammelt herauszugeben, hatte ich emstliche Bedenken. Es handelt sich ja urn ein Gebiet, das sich in stetiger Entwicklung befindet und in dem es heute moglich ware, manches klarer auszudriicken. Wie in der einleitenden Ubersicht zu einer als Universitats-Jahresschrift im Herbst 1929 erschienenen danischen Ausgabe der drei ersten Artikel, die nun in deutscher Ubersetzung den erst en Abschnitt des vorliegenden kleinen Buches bildet, erwahnt wurde, hoffe ich jedoch, daB eben die schrittweise Klarung der Begriffsbildung, wie sie in den Artikeln zum Vorschein kommt, einer solchen Ausgabe Interesse verleihen konne. Der hier noch hinzugefUgte vierte Artikel, der die deutsche Dbersetzung eines auf der skandinavischen Naturforscherversammlung Kopenhagen 1929 gehaltenen Vortrags ist, schlieBt sich zeitlich unmittelbar der obenerwahnten Dbersicht an und ebenso sachlich, indem er gewisser maBen als eine kurze Zusammenfassung des Inhaltes der vorhergehenden Artikel betrachtet werden kann. Bei dieser Herausgabe habe ich deshalb nur am SchluB der ein leitenden Ubersicht einige als Addendum bezeichnete Bemerkungen hinzugefUgt, die besonders die am Ende des vierten Artikels beriihrten Fragen des Verhaltnisses zwischen der Entwicklung der Atomtheorie und der Problemstellung der Biologie betreffen. Ganz abgesehen von dem selbstandigen Interesse, das solche Probleme auch uns den diesem Gebiete Femstehenden darbieten, mochte ich gem betonen, daB das Ein gehen auf Probleme der Biologie und Psychologie in den Artikeln vor allem daraufhinzielt, die physikalischen und erkenntnistheoretischen Pro bleme, denen wir in der Atomtheorie begegnet sind, in Relief zu stellen."

Dieser Buchtitel ist Teil des Digitalisierungsprojekts Springer Book Archives mit Publikationen, die seit den Anfangen des Verlags von 1842 erschienen sind. Der Verlag stellt mit diesem Archiv Quellen fur die historische wie auch die disziplingeschichtliche Forschung zur Verfugung, die jeweils im historischen Kontext betrachtet werden mussen. Dieser Titel erschien in der Zeit vor 1945 und wird daher in seiner zeittypischen politisch-ideologischen Ausrichtung vom Verlag nicht beworben.
