Polarlichter haben die Menschen schon seit frühen Zeiten erschreckt oder verzaubert. In Märchen Sagen und anderen Geschichten wurden Deutungen geschaffen, die sich um Götter, Helden, Fabelwesen oder auch Tiere ranken. Seit dem Altertum gibt es auch gelehrte Texte, in denen sich Philosophen, Chronisten und Wissenschaftler mit dieser Naturerscheinung befassen. Birgit und Kristian Schlegel gehen in ihrem reich illustrierten Buch den historischen Erklärungen zur Entstehung der Polarlichter nach, deren Rätsel erst im 20. Jahrhundert physikalisch ganz gelöst wurde. Aktuelle interdisziplinäre Forschungsergebnisse, die mit der Entstehung der Polarlichter in Verbindung stehen, werden anschaulich und wissenschaftlich präzise anhand zahlreicher Bilder und Diagramme erläutert.

As the sophistication of cyber-attacks increases, understanding how to defend critical infrastructure systems—energy production, water, gas, and other vital systems—becomes more important, and heavily mandated. Industrial Network Security, Second Edition arms you with the knowledge you need to understand the vulnerabilities of these distributed supervisory and control systems. The book examines the unique protocols and applications that are the foundation of industrial control systems, and provides clear guidelines for their protection. This how-to guide gives you thorough understanding of the unique challenges facing critical infrastructures, new guidelines and security measures for critical infrastructure protection, knowledge of new and evolving security tools, and pointers on SCADA protocols and security implementation. All-new real-world examples of attacks against control systems, and more diagrams of systems Expanded coverage of protocols such as 61850, Ethernet/IP, CIP, ISA-99, and the evolution to IEC62443 Expanded coverage of Smart Grid security New coverage of signature-based detection, exploit-based vs. vulnerability-based detection, and signature reverse engineering

The Higgs Fake

Does This Year's Nobel Prize In Physics Make Einstein Turn In His Grave?The Higgs Fake – How Particle Physicists Fooled the Nobel Committee is a merciless critique of the Large Hadron Collider at CERN and of the theoretical model on which the world's most expensive experiment is based. Unzicker, a German physicist and award-winning science writer, argues that the reaction of the Swedish Academy to last year's discovery appears to be a result of being beguiled by CERN's attempts to justify the billions of dollars of public money being spent.The book starts off by claiming that the greatest physicists such as Einstein, Dirac of Schrödinger would have considered the “discovery” of the Higgs particle ridiculous. The reasons, according to the author, are that: “1) the so-called standard model has grown unbelievably complicated, 2) none of the great riddles of physics that have persisted for a century have been solved, 3) history suggests that the current model is a dead end, 4) with their ever-more intricate experimental techniques, particle physicists are fooling themselves with alleged results, 5) scientific convictions in the community are established by blind faith in expert opinions, group-think and parroting, and 6) the data analysis in its complexity cannot be overseen by anybody.”Unzicker gives a historical survey of the field, and concludes that particle physics, as practiced since 1930, is “a futile enterprise in its entirety.” The book is peppered with a series of funny quotes from famous philosophers and scientists. In the last section, “Antidotes,” he specifically attacks “the overstated claims by famous physicists such as Rolf-Dieter Heuer, Michio Kaku, Lisa Randall, Sean Carroll, Brian Cox and Jim Al-Khalili.” At the end, Unzicker lists questions that he would like to be asked to particle physicists at press conferences, hearings and discussions.Unzicker's books have been praised as “well-grounded, sound, [and] informed,” and as “vehement pleading for physics as a natural science, in its best tradition,” but also dismissed by particle physicists as an “incoherent rant” and “time-wasting nonsense.” The new book, written in an even more explicit and provocative tone, is likely to upset the high energy physics community.Praise for previous books of the author:The assertion that “science means, after all, not being a sucker” is well worth taking to heart. – Publishersweekly A broad dismissal of modern theoretical physicists…Unzicker also targets the massive expenditures of funds on high-energy particle accelerators. – Kirkus ReviewsUnzicker dares to think outside the mainstream. A refreshing and provoking book... – Prof. Hans Volker Klapdor-Kleingrothaus, University of Heidelberg Timely needed revision of contemporary physics´ idiocies. – Prof. Antonio Ruiz de Elvira, University of Alcalá de Henares A passionate and profound search for scientific truth. Unzicker's questions to particle physicists at CERN are justified. PD Peter Thirolf, nuclear physicist at Munich University.A major contribution to physics... Unzicker is pointing out that the emperor is naked... The establishment scientists will curse and moan. – Edwin E Klingman, author, former NASA Research Physicist

All of science springs from the observation of nature. In this classic book, the late Professor Minnaert accompanies the reader on a tour of nature's light and color and reveals the myriad phenomena that may be observed outdoors with no more than a pair of eyes and an enquiring mind. From the intriguing shape of the dapples beneath a tree on a sunny day, via rainbows, mirages, and haloes, the colors of liquid, ice, and the sky, to the appearance of the sun, moon, planets, and stars - Minnaert describes and explains them all in a clear language accessible to laymen. This new English edition is supplemented by 80 plates, over half of them in color, taken by the acclaimed photographer Pekka Parviainen, illustrating many of the phenomena - ordinary and exotic - discussed in the book.

Educating For Intelligent Belief Or Unbelief

One of the most enduring and controversial issues in American education concerns the place of individual beliefs and moral standards in the classroom. Noddings argues that public schools should address the fundamental questions that teenagers inevitably rasie about the nature, value and meaning of life (and death), and to do so across the curriculum without limiting such existential and metaphysical discussions to separate religion, philosophy or even history classes. Explorations of the existence of a God or gods, and the value and validity of religious belief for societies or individuals, she writes “whether they are initiated by students or teachers, should be part of the free exchange of human concerns—a way in which people share their awe, doubts, fears, hopes, knowledge and ignorance.” Such basic human concerns, Noddings maintains, are relevant to nearly every subject and should be both non-coercive and free from academic evalution. “Nel Noddings probes the many ways in which children’s questions about God and gods, existence, and the meaning of life can and should be integrated into life in classrooms and the real world of the public schools.” —From the Foreword “This is a rich and sensitive book that will give teachers, administrators, parents, philosophers of education—any concerned citizen—the basis for more substantial discussion and concrete proposals.” —Free Inquiry “Impressive in its sweep of possibilities for exploration in the school curriculum and teacher education.” —Educational Theory
