Dealing with Uncertainties is an innovative monograph that lays
special emphasis on the deductive approach to uncertainties and on
the shape of uncertainty distributions. This perspective has the
potential for dealing with the uncertainty of a single data point
and with sets of data that have different weights. It is shown that
the inductive approach that is commonly used to estimate
uncertainties is in fact not suitable for these two cases. The
approach that is used to understand the nature of uncertainties is
novel in that it is completely decoupled from measurements.
Uncertainties which are the consequence of modern science provide a
measure of confidence both in scientific data and in information in
everyday life. Uncorrelated uncertainties and correlated
uncertainties are fully covered and the weakness of using
statistical weights in regression analysis is discussed. The text
is abundantly illustrated with examples and includes more than 150
problems to help the reader master the subject.
The extensive use of little known electronic principles provides
something like the Science of Electronics supplementing the Art of
Electronics without involvement of too much theory. Whereas art can
only be acquired by doing, the knowledge provided by science can be
acquired from books. The ready availability of integrated circuits
for practically any application reduces the art of electronics to
the art of interfacing these integrated components. The practical
knowledge required for that art can only be acquired by doing and
not by reading. However, it takes a lot of knowledge to select the
best integrated component for achieving a specific goal. Such
knowledge is provided in this book. By using a holistic approach in
the understanding of the various circuits and by taking ample
advantage of the duality between the electrical quantities voltage
and current, the understanding of the properties of electronic
circuits is made easier. Besides, this approach reduces the amount
of mathematics needed for a deeper understanding. Thus, this book
is appropriate for scholars at the advanced undergraduate level. In
particular, the important aspects of positive and negative feedback
in circuits are presented in a compact way by introducing the
reverse closed-loop-gain. It is quite clear that a single book
cannot cover all aspects of both analog and digital electronics,
the latter comprising all circuits needed for data manipulation in
digital computers- which is a field in itself.
In fast allen Wissenschaftsgebieten nehmen heute elektronische MeB-
methoden einen hervorragenden Platz ein. Besonders gilt dies fur
die Kern- physik bzw. Kerntechnik, in der oft hOchste Anspruche an
die MeBgerate gestellt werden. Urn aber fur eine gestellte
meBtechnische Aufgabe die elek- tronischen Anforderungen richtig
abzuschatzen bzw. die Moglichkeiten einer vorgegebenen Apparatur zu
erkennen, muB der experimentelle Wissen- schaftler bereits uber
eine beachtliche Kenntnis der Elektronik verfugen. Auch die
Fahigkeit, bei einer MiBfunktion eines elektronischen Gerates den
Fehler erkennen, lokalisieren und beheben zu konnen, ist in der
Praxis einer effektiven Forschungsarbeit von groBter Wichtigkeit.
SchlieBlich erfordert die Kombination verschiedener MeBeinheiten,
die oft von verschiedenen Herstellern stammen, ein genaues
Verstandnis der Anpassungsbedingungen; die Befahigung, wo notig,
einfache Ubergangseinheiten selbst herstellen zu konnen, erspart
viel Zeit und Geldmittel. Der zunehmende Einsatz integrierter
Bauelemente in den letzten Jahren ermoglicht es einerseits,
komplexe elektronische Anlagen in sehr kompakter Bauweise zu
konstruieren, kommt aber andererseits auch der elektronischen
Betatigung der Wissenschaftler entgegen, deren Ziel nicht die
Entwicklung elektronischer Apparaturen ist, sondern fur die diese
nur unentbehrliche Hilfsgerate darstellen. Denn bei Verwendung
dieser integrierten Elemente erfolgt die Dimensionierung fast zur
Ganze durch den Hersteller, der bereits funktionsfahige
Baueinheiten zur Verfugung stellt. Es genugt dann, uber die
allgemein giiltigen elektronischen Grundlagen Bescheid zu wissen,
urn in Verbindung mit den technischen Daten der verwendeten
Elemente zu einem Verstandnis der vorliegenden Schaltungen zu
kommen.
