Classical electromagnetism - one of the fundamental pillars of
physics - is an important topic for all types of physicists from
the theoretical to the applied. The subject is widely recognized to
be one of the most challenging areas of the physics curriculum,
both for students to learn and for lecturers to teach. Although
textbooks on electromagnetism are plentiful, hardly any are written
in the question-and-answer style format adopted in this book. It
contains nearly 300 worked questions and solutions in classical
electromagnetism, and is based on material usually encountered
during the course of a standard university physics degree. Topics
covered include some of the background mathematical techniques,
electrostatics, magnetostatics, elementary circuit theory,
electrodynamics, electromagnetic waves and electromagnetic
radiation. For the most part the book deals with the microscopic
theory, although we also introduce the important subject of
macroscopic electromagnetism as well. Nearly all questions end with
a series of comments whose purpose is to stimulate inductive
reasoning and reach various important conclusions arising from the
problem. Occasionally, points of historical interest are also
mentioned. Both analytical and numerical techniques are used in
obtaining and analyzing solutions. All computer calculations are
performed with MathematicaCO (R) and the relevant code is provided
in a notebook; either in the solution or the comments.
Galileo Unbound traces the journey that brought us from Galileo's
law of free fall to today's geneticists measuring evolutionary
drift, entangled quantum particles moving among many worlds, and
our lives as trajectories traversing a health space with thousands
of dimensions. Remarkably, common themes persist that predict the
evolution of species as readily as the orbits of planets or the
collapse of stars into black holes. This book tells the history of
spaces of expanding dimension and increasing abstraction and how
they continue today to give new insight into the physics of complex
systems. Galileo published the first modern law of motion, the Law
of Fall, that was ideal and simple, laying the foundation upon
which Newton built the first theory of dynamics. Early in the
twentieth century, geometry became the cause of motion rather than
the result when Einstein envisioned the fabric of space-time warped
by mass and energy, forcing light rays to bend past the Sun.
Possibly more radical was Feynman's dilemma of quantum particles
taking all paths at once - setting the stage for the modern fields
of quantum field theory and quantum computing. Yet as concepts of
motion have evolved, one thing has remained constant, the need to
track ever more complex changes and to capture their essence, to
find patterns in the chaos as we try to predict and control our
world.
Tobias Schuttler stellt in diesem essential beide im Detail sehr
anspruchsvollen Gebiete - Einsteins beruhmte Relativitatstheorie
und die Satellitenortung mit GPS und Galileo - in allgemein
verstandlicher Weise dar und erklart die Einflusse der
Relativitatstheorie bei der Satellitennavigation ohne hoehere
Mathematik. Es werden auch die zu dieser Betrachtung wichtigen
Formeln genannt und motiviert. Um die Einflusse der
Relativitatstheorie auf ein Satellitennavigationssystem wie das
europaische Galileo zu verstehen, muss man sich mit dem konkreten
Messvorgang bei der Ortung auseinandersetzen. Die Grundidee des
Verfahrens ist einfach - die technische Umsetzung indes hoechst
komplex.
