Until now no overview of the Quaternary deposits of northeastern
Europe has been available. This book fills the gap. It presents the
state of research on Quaternary stratigraphy and geology, with
emphasis on glacial deposits, discusses the general scientific
ideas and gives an overview of the methods of investigation, some
of which have rarely been applied elsewhere. It has become apparent
that the region covered has many environmental problems, and a
proper understanding of the Quaternary deposits is a basic
requirement for dealing with them. The same is true for civil
engineering. In the formerly glaciated areas almost all
construction sites for roads and houses will encounter glacial
deposits. This volume provides an authoritative and fascinating
overview for anyone planning to venture into this field. In its 53
regional chapters the book covers Finland, Estonia, Latvia,
Lithuania, Russia, Ukraine, Belarus, Poland, the Czech Republic and
eastern Germany. From the text it becomes clear that not all the
stratigraphical schemes are yet fully compatible or comprehensible.
There can be no doubt, however, that the east was subjected to very
extensive ice advances during the earlier Pleistocene. Also, in
contrast to western Europe, there was a significant Early
Weichselian ice advance, although not as extensive as the last,
Late Weichselian event. The book is illustrated by 421 figures and
74 colour plates (mostly photographs). There are 23 tables, a
detailed index and a list of over 1000 references, providing a
unique collection of northeastern European geoscience literature,
much of which has so far escaped the attention of western
scientists. The volume, composed of contributions by 60 scientists,
completes the trilogy on glacial deposits of northern Europe.
Together with its two companion volumes, the Glacial deposits in
North-West Europe and the Glacial Deposits in Great Britain and
Ireland, it represents an invaluable source of information for the
geoscientist, the advanced student or the amateur.
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 been interspersed
with relatively short warmer intervals like the one we live in
today. The book focuses on the changing state of these glaciers and
the effects of associated climate changes on a wide variety of
environments (including mountains, rivers, deserts, oceans and
seas) and also plants and animals. For example, at times the Sahara
was green and colonized by humans, and Lake Chad covered 350,000
km2 larger than the United Kingdom. What happened during the ice
age can only be reconstructed from the traces that are left in the
ground. The work of the geoscientist is similar to that of a
detective who has to reconstruct the sequence of events from
circumstantial evidence. The book draws on the specialisms and
experience of the authors who are experts on the glacial history of
the Earth. Readership: Undergraduate and postgraduate students
studying the Quaternary, researchers, and anyone interested in
climate change, environmental change and geology. The book provides
a rich collection of illustrations and photographs to help the
readers at all levels visualise the dramatic consequences of
glacier expansions during the Ice Age.
The book presents an up-to-date, detailed overview of the
Quaternary glaciations all over the world, not only with regard to
stratigraphy but also with regard to major glacial landforms and
the extent of the respective ice sheets. The locations of key sites
are included. The information is presented in digital, uniformly
prepared maps which can be used in a Geographical Information
System (GIS) such as ArcView or ArcGIS. The accompanying text
supplies the information on how the data were obtained
(geomorphology, geological mapping, air photograph evaluation,
satellite imagery), how the features were dated (14C, TL, relative
stratigraphy) and how reliable they are supposed to be. All
references to the underlying basic publications are included. Where
controversial interpretations are possible e.g. in Siberia or
Tibet, this is pointed out. As a result, the information on
Quaternary glaciations worldwide will be much improved and supplied
in a uniform digital format. The information on the glacial limits
is compiled in digital form by the coordinators of the project, and

Die Quantenmechanik hat seit ihrem Beginn immer wieder diskutierte
Pro- bleme in Bezug auf ihre "Interpretation" gestellt. Auch heute
noch wer- den die Fragen nach der Rolle des Bewusstseins, nach
Objektivitat oder Subjektivitat, nach der Bedeutung der sogenannten
"Reduktion der Wellen- pakete" mit aller Leidenschaftlichkeit
diskutiert. Viele meinen, dass nur eine AEnderung der klassischen
Aussagelogik zu einer mehrwertigen "Wahr- scheinlichkeitslogik" es
ermoeglicht, die Quantenmechanik zu interpretieren. Die
Leidenschaftlichkeit, mit der alle diese Fragen diskutiert werden,
zeigt zweierlei: 1. Dass die Grundaussagen der Quantenmechanik
begrifflich viel zu ver- schwommen sind, so dass die einzelnen
durchaus verschiedene In- halte bei Benutzung desselben Wortes
meinen. Solche unklaren Be- griffe sind "Zustand", "Observable",
"Beobachter", "Eigenschaft", "Aussage" (Proposition) und ahnliche.
2. Dass die Diskussion der vermeintlich nur physikalischen Fragen
tat- sachlich in der Tiefe beherrscht wird von "philosophisch -
weltan- schaulichen" Vorentscheidungen. Die entscheidende
Grundstruktur derQuantenmechanik, die zu den erwahn- ten
Fragestellungen fuhrt, ist die Benutzung von Operatoren des
Hilbert- raumes zur Beschreibung der Wahrscheinlichkeit von
Messergebnissen, wie es kurz in Kapitel I rekapituliert wird.
Kapitel I versucht die bekannte Zusammenfassung der
quantenmechanischen Grundpostulate nach J. v. Neumann zu
formulieren, damit der Leser an Bekanntes anschliessen kann.
Kapitel I erhebt daher keinen Anspruch, eine systematische
axiomatische Formulierung im Sinne der Mathematik zu sein; IV im
Gegenteil soll Kapitel I als Zusammenfassung heuristischer
Prinzipien noch einmal, kurz die "Bedurftigkeit" nach einer echten
Grundlegung der Quantenmechanik aufweisen.
From the author of Eat Bananas and Follow Your Heart comes a new
collection of personal essays on life, baseball, and things that
matter. Part memoir and part reflection, lawyer and writer Mark J.
Ehlers addresses life in all its dimensions; the passage of time
and of unmet dreams, the conflicts of faith in a secular age, the
redeeming quality of the human spirit, and a lifelong bond with
baseball. It is for anyone who believes that life is too precious
to cease thinking and learning, and recognizes that, in the words
of Abraham Joshua Heschel, "There is no human being who does not
carry a treasure in his soul: a moment of insight, a memory of
love, a dream of excellence..." "I believe human interaction is at
its best when people are not afraid to reveal themselves, when we
are open to civil discourse and healthy give-and-take on matters of
substance. Besides, the weather has never been all that interesting
to me." --from Life Goes On
From his inspirational and thought-provoking blog "Ehlers on
Everything" comes a collection of interesting and touching essays
on life, politics, baseball and religion by Mark J. Ehlers. "Eat
Bananas and Follow Your Heart: Essays on Life, Politics, Baseball
and Religion" is a book for anyone who believes that life is too
short to remain uninvolved, time too precious to cease learning,
thinking, caring, and laughing.
