This book is a brief and accessible popular science text intended
for a broad audience and of particular interest also to science
students and specialists. Using a minimum of mathematics, a number
of qualitative and quantitative examples, and clear illustrations,
the author explains the science of thermodynamics in its full
historical context, focusing on the concepts of energy and its
availability and transformation in thermodynamic processes. His
ultimate aim is to gain a deep understanding of the second
law—the increase of entropy—and its rather disheartening
message of a universe descending inexorably into chaos and
disorder. It also examines the connection between the second law
and why things go wrong in our daily lives. Readers will
enhance their science literacy and feel more at home on the science
side of author C. P. Snow's celebrated two-culture,
science-humanities divide, and hopefully will feel more at home in
the universe knowing that the disorder we deal with in our daily
lives is not anyone's fault but Nature's.

Heinz Mack (*1931) has been working as a sculptor and painter for
more than sixty years. From the ZERO period in around 1960 to the
present day he has created a wide-ranging work whose essential
aspects, such as the significance of light, structure and colour
are portrayed with often surprising perspectives. The authors
accompany Mack in his constant search for a new concept of art,
thereby discovering little-known connections to Minimal Art, Land
Art, Yves Klein and Constantin Brancusi. The journey through Mack's
rich oeuvre culminates finally in his passionate plea for the "idea
of beauty in the 21st century". Heinz Mack is an artist who has
left his mark on our times. He has made a pioneering contribution
to the question of a new concept of art, which has been of
fundamental importance since the post-war period. This volume
offers for the first time a monograph with an overview of Mack's
philosophy of art as well as his multi-faceted oeuvre: from ZERO
and the legendary Sahara Project to light art and his most recent
paintings.
Unsere Untersuchungen haben gezeigt, dass sich die bekannten
Usability Tests durchaus zur Evaluierung von Multitouch-Systemen
eignen. Sie m ssen allerdings an die Eigenheiten und Besonderheiten
der Technologie angepasst werden. Wir untersuchten und optimierten
die folgenden drei Usability-Methoden: Expertenevaluation Usability
Experten, die Multitouch-Systeme evaluieren, m ssen mit der
Technologie vertraut sein und deren spezielle Eingeschaften kennen.
Sie m ssen sich bewusst sein, dass z.B. Aspekte wie
Hardwareergonomie und Einsatzort gro en Einfluss auf die Usability
eines Multitouch-Systems haben. Das zu untersuchende System muss
von ihnen mit spezifischen Kriterien betrachtet und bewertet
werden, wozu entsprechendes Fachwissen vorhanden sein muss. Dazu k
nnen die von uns verfassten Guidelines als Grundlage dienen. Wir
bieten weiterhin einen auf den Grunds tzen der Dialoggestaltung
basierenden und um multitouch-spezifische Faktoren erweiterten
Evaluierungsbogen an. Paper Prototype Die betragung von Gesten auf
einen Paper Prototype f llt vielen Testpersonen sehr schwer. Er
kann also nicht eingesetzt werden, um gezielt Erkenntnisse in
diesem Bereich zu erlangen. Weiterhin lassen sich f r
Multiuser-Anwendungen Tests mit mehreren Nutzern nur in begrenztem
Rahmen durchf hren. Der Paper Prototype ist nicht flexibel genug,
um von mehreren Probanden gleichzeitig bedient zu werden. Weiterhin
k nnen Aussagen ber die Hardwareergonomie eines Produkts nur dann
getroffen werden, wenn der u ere Aufbau dem finalen Produkt
weitestgehend entspricht. Ist man sich dieser Aspekte bewusst, kann
der Paper Prototype jedoch bereits zu einem sehr fr hen Stadium der
Entwicklung R ckschl sse zur Informationsarchitektur und
Hardwareergonomie eines Produkts erm glichen. Classic Usability
Test Beim Classic Usability Test sollte in jedem Fall eine
Nachbesprechung mit den Testpersonen durchgef hrt werden. Diese
Nachbesprechung kann erg nzend zum eigentlichen Test wichtige

“There is no substitute for the happiness which colours give
me.” After a long break, Heinz Mack has been focusing intensively
on painting again for over thirty years. A cross-section of his
"Chromatische Konstellationen" from 1991 until the present day
shows how he translates the greatest possible purity of colour,
light and immateriality into a broad spectrum of colour sequences
and structures. Texts by Heinz Mack and Robert Fleck illuminate the
essence of these colour worlds. Colour as light and light as colour
– this represents, as it were, the nucleus of Mack’s painting.
Within this premise he offers us a wide variety: chapters on, for
example, the primacy of colour, atmosphere and nature, space,
movement and geometric forms show the fascinating bandwidth of his
work. The volume closes with an unusual undertaking: in a personal
juxtaposition with works from art history from Duccio to Barnett
Newman, the artist grants us an insight into his collective
pictorial memory.
