./ PREFACE 

I* 

Although several German-English scientific and technological 
dictionaries, both general and special, are available, up to this time 
there has been no bilingual dictionary of physics. Now that there is an 
unparalleled upsurge of interest in the physical sciences, a really adequate 
dictionary in the field of physics will be more valuable than ever. 

This German-English Dictionary of Physics and Allied Sciences 
extends its scope beyond theoretical physics proper not only to the 
principal terms of related sciences such as mathematics, astronomy, 
chemistry, mineralogy, geology, geophysics, and meteorology; it also 
goes into their application in the various branches of technology and 
engineering such as electronics, radio, television, telephony, telegraphy, 
navigation, aviation, and ballistics. 

This dictionary includes as far as possible the essential features 
that make a dictionary a helpful tool for reading and translating. 
Not only are parts of speech indicated, but special divisions are given 
with explanations in parentheses for different meanings of a key word, 
as well as for model phrases and sentences showing the application 
and grammatical construction of key words. Words of the general 
language have been included that are frequently used in the scientific 
language of physics or related sciences, especially those words that have 
assumed technical meanings of their own. 

These particular features will make this dictionary useful not only 
to theoretical physicists engaged in basic research and those active 
in the applied sciences such as engineers, chemists and metallurgists, 
but also to teachers, students, translators, and all who are interested 
in the literature of physics or the related sciences. 

This Dictionary of Physics and Allied Sciences is based on a 
comprehensive stockpile of entries in pertinent fields of science and 
technology, compiled in decade-long research by Dr. Robert Grossbard 
in collaboration with a staff of experts in the various fields. 

The editor, Charles J. Hyman, a former professor of mathematics 
and physics at the University of the Philippines and a former member 
of the U.S. Coast and Geodetic Survey, now a translator of scientific 
and technological books, carried out the task of editing the compiled 
material. 



Those involved in preparing this dictionary are well aware of the 
unavoidable limitations of a work of this kind, particularly from a 
bilingual standpoint. We believe, nevertheless, that the Dictionary of 
Physics and Allied Sciences will prove to be a practical tool for those 
who wish to read and translate German scientific text dealing with 

the physical sciences. 

THE PUBLISHERS 



VORWORT 



Obwohl mehrere deutsch-englische naturwissenschaftlich-techni- 
sche Worterbiicher vorhanden sind, allgemeine sowohl wie spezielle, 
hat es doch bisher an einem Worterbuch der Physik gefehlt. Mehr als 
je muB jetzt, nach einer so gewaltigen Steigerung des Interesses an 
den physikalischen Wissenschaften ein umfassendes Worterbuch auf 
diesem Gebiet einem Bediirfnis entsprechen, 

Das vorliegende Werk geht nicht nur iiber die theoretische Physik 
hinaus in die Gebiete der Mathematik, Astronomic, Chemie, Mineralogie, 
Geologic, Geophysik und Meteorologie, indem es deren wesentliche 
Fachausdriicke einbezieht, sondern behandelt auch die Anwendung 
dieser Wissenschaften in den verschiedenen Fachern der Technik und 
des Ingenieurwesens, wie Elektronik, Radio, Fernsehen, Fernsprech- 
wesen, Telegraphic, Schiffahrt, Flugwesen und Ballistik. 

Besondere Sorgfalt ist an den lexikographischen Aufbau des Werkes 
gewendet worden, indem alle Hilfsmittel herangezogen wurden, die die 
Niitzlichkeit eines Worterbuchs fur tfbersetzung und Lektiire erhohen. 
Nicht nur sind die Redeteile bezeichnet, es sind auch besondere Ein- 
teilungen mit Klammererklarungen fiir verschiedene Bedeutungen eines 
Stichworts gegeben, ebenso wie Musterbeispiele von Phrasen und 
Satzen, die Anwendung und grammatische Konstruktion der Stich- 
wSrter veranschaulichen. Worter der allgemeinen Sprache, die in der 
Fachsprache der Physik und verwandter Wissenschaften haufig ge- 
braucht werden, sind ebenfalls einbezogeo, besonders wenn sie fachliche 
Bedeutungen angenommen haben. 

Durch die dargestellte lexikographische Anlage wird das vorliegende 
WSrterbuch nicht nur dem theoretischen Physiker, der mit Grundlagen- 
forschung beschaftigt ist, und dem Praktiker der angewandten Wissen 
schaften, wie dem Ingenieur, Chemiker und Metallurgen eine will- 
kommene Hilfe bieten, sondern auch dem Lehrer, Studenten und 
Ubersetzer, iiberhaupt jedem, der sich mit den Gebieten der Physik 
und der ihr nahestehenden Wissenschaften befafit. 

Die vorliegende Arbeit griindet sich auf umfassendes Material aus 
den einschlSgigen Gebieten in Wissenschaft und Technik, das in jahr- 
zehntelanger Sammelarbeit von Dr, Robert Grossbard unter Mithilfe 



eines Stabes von Sachverst&ndigen in den vcrschiedcnen Fachgebicten 
zusammengestellt wurde. 

Der Herausgeber Charles J. Hyman, ehemals Professor der Mathe- 
inatik und Physik an der Universit&t der PhiKppinen und Mitglied der 
Kiisten- und Vermessungskommission der Vereinigten Staaten, gegen- 
wSrtig Ubersetzer und Bearbeiter wissenschaftlicher und technischer 
Werke, hat die Redaktionsarbeit an dem kompilierten Material dutch- 
gefiihrt. 

Alle Mitarbeiter an dem vorUegenden Werk sind sich der unver- 
meidlichen Schranken, die einer solchen Arbeit insbesondere vom 
Gesichtspunkt der Zweisprachigkeit aus gesctxt sind, wohl bewufit* 
Nichtsdestoweniger darf die HoflFnung ausgesprochen werden, dafi sich 
das WSfterbuch der Physik und verwandter Wissewchaften fiir aUe, die 
deutsche Texte auf den einscMSgigen Gebieten lesen und iibersetzen, 
als ein wertvolles Hilfsiruttel erweisen wird.
