"The theory, observations, and applications ofgravitational lensingconstitute one ofthe most rapidly growing branches ofextragalactic astrophysics. The deflection of light from very distant sources by intervening masses provides a unique possibility for the investigation of both background sources and lens mass distributions. Gravitational lensing manifestsitselfmost distinctly through multiply imaged QSOs and the formation of highly elo ..."
"This book provides a new look at the climatic history of the last 2.6 million years during the ice age, a time of extreme climatic fluctuations that have not yet ended. This period also coincides with important phases of human development from Neanderthals to modern humans, both of whom existed side by side during the last cold stage of the ice age. The ice age has seen dramatic expansions of glaciers and ice sheets, although this has b ..."

"This book is the last of three volumes in which the recent knowledge of the extent and chronology of Quaternary glaciations has been compiled on a global scale. This information is seen as a fundamental requirement, not only for the glacial community, but for the wider user-community of general Quaternary workers. In particular the need for accurate ice-front positions is a basic requirement for the rapidly growing field of palaeoclimat ..."

Die Idylle trügt(1st Edition) (German Edition) by JürgenEhlers Paperback, 280 Pages, Published 2014 by Createspace Independent Publishing Platform ISBN-13: 978-1-5031-8523-4, ISBN: 1-5031-8523-0
"19 Kurzkrimis. Alle haben gemeinsam, dass es sich um höchst ungewöhnliche Kriminalfälle handelt – ganz gleich, ob nun nur die Kreditkarte des Kanzlers entwendet werden soll, oder ob es um vierzigfachen Mord geht. Die Leichen liegen in und um Hamburg, aber auch anderswo – zum Beispiel in Montevideo und in Jekaterinburg im südlichen Ural. Petja hat dem Erzähler eingeredet, er sei ein Enkel der Zarenfamilie. Unsinn, sagt sein Vater. Aber w ..."
"Light observed from distant objects is found to be deflected by the gravitational field of massive objects near the line of sight - an effect predicted by Einstein in his first paper setting forth the general theory of relativity, and confirmed by Eddington soon afterwards. If the source of the light is sufficiently distant and bright, and if the intervening object is massive enough and near enough to the line of sight, the gravitationa ..."
"Dieses Buch ist bis heute eine der populärsten Darstellungen der Relativitätstheorie geblieben. In der vorliegenden Version haben J. Ehlers und M.

"Gebundenes BuchDas Eiszeitalter ist eine Zeit extremer Klimaschwankungen, die bis heute nicht beendet sind. Zeitweilig bedeckten gewaltige Inlandeismassen große Teile der Nordkontinente. Zu anderen Zeiten war die Sahara grün und von Menschen besiedelt, und der Tschadsee war so groß wie die Bundesrepublik Deutschland. Was sich im Eiszeitalter abgespielt hat, kann nur aus Spuren rekonstruiert werden, die im Boden zurückgeblieben sind. Die ..."
Canonical Gravity(Reprint) From Classical to Quantum: Proceedings of the 117th WE Heraeus Seminar Held at Bad Honnef, Germany, 13–17 September 1993 (Lecture Notes in Physics) by JürgenEhlers, Helmut Friedrich Paperback, 372 Pages, Published 2013 by Springer ISBN-13: 978-3-662-13954-7, ISBN: 3-662-13954-5
"The search for a quantum gravity theory, a theory expected to combine the principles of general relativity and quantum theory, has led to some of the most deepest and most difficult conceptual and mathematical questions of modern physics. The present book, addressing these issues in the framework of recent versions of canonical quantization, is the first to present coherently the background for their understanding. Starting with an anal ..."
Special Relativity Will it Survive the Next 101 Years? (Lecture Notes in Physics) by JürgenEhlers, Claus Lämmerzahl Paperback, 552 Pages, Published 2014 by Springer ISBN-13: 978-3-642-42113-6, ISBN: 3-642-42113-X
"After about a century of success, physicists feel the need to probe the limits of validity of special-relativity base theories. This book is the outcome of a special seminar held on this topic. The authors gather in a single volume an extensive collection of introductions and reviews of the various facets involved, and also includes detailed discussion of philosophical and historical aspects.
