This book offers a perfect combination of classical optics and its use in understanding observable phenomena in nature and our surroundings. The science topics of the first part are those typically covered in undergraduate courses on optics. The author gives clear and concise introductions to geometrical optics, wave optics, detectors, and light sources. He also addresses radiometry, photometry, colorimetry, as well as quantum optics of light-matter interactions. End of chapter exercises help readers to test and consolidate their knowledge.In the second part of the book, a vast number of applications are presented both qualitatively and quantitatively. They include everyday atmospheric optical phenomena such as rainbows, halos, coronas, glories, mirages, sky colors etc., but also the colors of water, green flashes, the question how far we are able to see and many others. Stunning images of many natural optical phenomena will add greatly to the reader’s enjoyment of this book.The English translation of this book, originally in German, was facilitated by artificial intelligence. The content was later completely revised by the author for accuracy.

This new up-to-date edition of the successful handbook and ready reference retains the proven concept of the first, covering basic and advanced methods and applications in infrared imaging from two leading expert authors in the field. All chapters have been completely revised and expanded and a new chapter has been added to reflect recent developments in the field and report on the progress made within the last decade. In addition there is now an even stronger focus on real-life examples, with 20% more case studies taken from science and industry. For ease of comprehension the text is backed by more than 590 images which include graphic visualizations and more than 300 infrared thermography figures. The latter include many new ones depicting, for example, spectacular views of phenomena in nature, sports, and daily life.

Eine Intellektuellengeschichte des 20. Jahrhunderts muss die geistigen Einflüsse deutscher Wissenschaftsemigranten zwischen 1933 und 1945 berücksichtigen. Zu einschneidend prägte sie das literarische, kulturelle und politische Denken diesseits und jenseits des Atlantiks. Aus einem breiten Verständnis von Ideengeschichte heraus werden nicht nur prominente Emigranten wie Hannah Arendt, Arnold Bergstraesser und Franz L. Neumann, sondern zugleich dem drohenden Vergessen anheim fallende Flüchtlinge wie Sigmund Neumann, Ferdinand Hermens und Otto Neurath oder bisher kaum beachtete Biographien von André Gorz und Romain Rolland vorgestellt. Einerseits rekonstruieren die Beiträge die dramatischen Lebenslinien sowie die oft unter beklemmenden Bedingungen angefertigten politischen, gesellschafts-, kultur- und wissenschaftstheoretischen Arbeiten. Andererseits wagen sie auch einen Blick auf die Perspektiven der Emigrationsforschung heute.​

Optical Properties of Metal Clusters deals with the electronic structure of metal clusters determined optically. Clusters - as state intermediate between molecules and the extended solid - are important in many areas, e.g. in air pollution, interstellar matter, clay minerals, photography, heterogeneous catalysis, quantum dots, and virus crystals. This book extends the approaches of optical molecular and solid-state methods to clusters, revealing how their optical properties evolve as a function of size. Cluster matter, i.e. extended systems of many clusters - the most frequently occuring form - is also treated. The combination of reviews of experimental techniques, lists of results and detailed descriptions of selected experiments will appeal to experts, newcomers and graduate students in this expanding field.

Die Dokumentation zieht eine Zwischenbilanz des ersten in Deutschland akkreditierten Studiengangs Sozialmanagement an der Ostfalia vor fünfzehn Jahren. Neben Beispielen zur Etablierung des weiterbildenden Fernstudiengangs wird der Diskussionsstand um das Feld Sozial- und Public Management gekennzeichnet.

Dieses Lehr-, Lern-, Fach- und Sachbuch präsentiert die Grundlagen der Optik in Theorie und ausführlich beschriebenem Experiment sowie vielfältige faszinierende optische Phänomene.
