Akustik und Raumklima: Raumkomfortbewertung und Energieeffizienz (essentials)
by Armin Raabe Peter HolsteinObwohl in diesem essential akustische Messmethoden in Räumen und Gebäuden behandelt werden, ist hier Akustik nicht als Bauakustik zu verstehen. Zusätzlich zu herkömmlichen Methoden zur Bewertung des Innenraumklimas und für eine energieeffiziente Klimatisierung lassen sich mit akustischen Methoden Informationen gewinnen, die bei der Raumklimagestaltung von Nutzen sein können:- zur Analyse von Schallgeschwindigkeitsverteilungen als Informationsquelle über Temperatur- und Strömungsfelder in Räumen,- zur akustischen Detektion von Undichten zum Nachweis unerwünschter Be- bzw. Entlüftung und damit von Energieverlusten.Die Verfahren stammen zum Teil aus anderen Wissensgebieten, u.a. der Meteorologie, Tomografie oder der bildlichen Darstellung von Schallquellen. Damit können sie als Alternativen und Ergänzungen zu den herkömmlichen Methoden einer energieeffizienten Raumklimagestaltung verstanden werden.
Akzeptanz von In-vitro-Fleisch und pflanzenbasierten Fleischersatzprodukten in Deutschland: Eine Anwendung der Theorie der kognitiven Hierarchie (BestMasters)
by Maresa Anna TemmenMaresa Anna Temmen untersucht auf Grundlage der Theorie der kognitiven Hierarchie die Konsumbereitschaft für In-vitro-Fleisch und pflanzenbasierte Fleischersatzprodukte in Deutschland. Hierzu werden unter anderem ernährungspsychologische Einflussfaktoren genutzt, die sich auf moralische und ideologische Einstellungen zum Fleischkonsum beziehen. Die Ergebnisse der quantitativen Online-Fragebogenstudie zeigen, dass die Konsumbereitschaft für In-vitro-Fleisch und pflanzenbasierte Fleischersatzprodukte in der deutschen Bevölkerung relativ hoch ist und stützen die Theorie der kognitiven Hierarchie: Entsprechend können eine universalistisch geprägte Wertestruktur, eine geringe soziale Dominanzorientierung, eine geringe Ausprägung von Speziesismus und karnistischer Dominanz sowie eine geringe Unterstützung von Rechtfertigungsstrategien für den Konsum von Fleisch Gründe für eine hohe Konsumbereitschaft von In-vitro-Fleisch und pflanzenbasierten Fleischalternativen sein. Die Studie zeigt, dass tiefliegende Persönlichkeitsvariablen wie Werte und Wertorientierungen einen Einfluss auf spezifischere Einstellungen nehmen, die wiederum einen Einfluss auf die Konsumbereitschaft von Fleischalternativen haben.
Akzeptanzkommunikation in der Energie- und Rohstoffwirtschaft: Chancen und Grenzen für kleine und mittlere Unternehmen zur Verbesserung des Akzeptanzniveaus am Beispiel des Freistaats Sachsen
by Stefanie WalterDiese Open-Access-Publikation untersucht die Akzeptanz der sächsischen Bevölkerung gegenüber Energie- und Rohstoffvorhaben sowie die Eignung von Kommunikationsmaßnahmen zur Verbesserung des Akzeptanzniveaus. Die Bürger:innen werden erstmals repräsentativ zu ihrer (In-)Akzeptanz gegenüber Anlagearten befragt. Dabei wird nachgewiesen, dass die Akzeptanz bei lokalen Projekten immer geringer ist als soziopolitisch. Bei den erneuerbaren Energieumwandlungsanlagen ist die Akzeptanz gegenüber Wasserkraft- und Solaranlagen am höchsten, gegenüber Biomasseanlagen am geringsten. Fossile Energieumwandlungsanlagen sind weniger akzeptiert und Tage- und Untertagebaue werden am schlechtesten bewertet. Eine vergleichende Befragung der Unternehmensvertreter:innen des Energie- und Rohstoffsektors ergibt eine Dissonanz der von ihnen angenommenen zur erfassten (In-)Akzeptanz der Bevölkerung: Das Akzeptanzniveau ist unabhängig von der Art des Vorhabens geringer, als es die Unternehmensvertreter:innen annehmen.Die Erkenntnisse werden genutzt, um eine Webapplikation zu entwickeln, die es insbesondere kleinen und mittleren Unternehmen ermöglicht, zur Akzeptanzsteigerung geeignete Kommunikationsmaßnahmen auszuwählen.

Alabama Gold: A History of the South’s Last Mother Lode
by Peggy Jackson WallsGold rushes in Cleburne and Tallapoosa Counties attracted thousands of miners years before California's famous strike. In 1936, production at the Hog Mountain mine caused Alabama to be recognized as the top producer in the Appalachian states. In Hog Mountain's heyday, a local German settler discovered the precious metal while digging a wine cellar. In Log Pit, unscrupulous speculators "shot" ore into rock crevices and "salted" nuggets on land to enhance its sale value. A Cleburne County miner cleaned over eleven pounds of gold and was killed in a "free fight" all in one day. Join author Peggy Jackson Walls as she traces a century of gold mining in Alabama.
Alameda County Fire Department (Images of America)
by Firefighter Heather MarquesAlameda County spans from the shores of the San Francisco Bay to the golden inland hills. Alameda County Fire Department (ACFD) is comprised of multiple consolidated agencies that began joining forces and sharing resources in 1993. Protecting unincorporated county land as well as Ashland, Cherryland, San Lorenzo, Castro Valley, San Leandro, Dublin, Union City, Newark, Emeryville, and the National Laboratories at Livermore and Berkeley, ACFD serves over 500 square miles and 330,000 citizens. This legacy stretches back 140 years, recalling the shared experiences of bucket brigades, teams of horses pulling steam-engine pumpers down muddy roads, the advent of motorized apparatus, and the days when school boys would be pulled from class to ride tailboard to fight blazes in the hills. These agencies have sent soldiers to two world wars, survived massive earthquakes, fought catastrophic wildfires, and touched the lives of Bay Area citizens for over a century. The ACFD is the sum of its many unique parts, which together form a premier, all-risk fire department.

Alan Turing: The Book That Inspired the Film The Imitation Game - Updated Edition
by Andrew HodgesA NEW YORK TIMES BESTSELLERThe official book behind the Academy Award-winning film The Imitation Game, starring Benedict Cumberbatch and Keira KnightleyIt is only a slight exaggeration to say that the British mathematician Alan Turing (1912–1954) saved the Allies from the Nazis, invented the computer and artificial intelligence, and anticipated gay liberation by decades—all before his suicide at age forty-one. This New York Times bestselling biography of the founder of computer science, with a new preface by the author that addresses Turing&’s royal pardon in 2013, is the definitive account of an extraordinary mind and life.Capturing both the inner and outer drama of Turing&’s life, Andrew Hodges tells how Turing&’s revolutionary idea of 1936—the concept of a universal machine—laid the foundation for the modern computer and how Turing brought the idea to practical realization in 1945 with his electronic design. The book also tells how this work was directly related to Turing&’s leading role in breaking the German Enigma ciphers during World War II, a scientific triumph that was critical to Allied victory in the Atlantic. At the same time, this is the tragic account of a man who, despite his wartime service, was eventually arrested, stripped of his security clearance, and forced to undergo a humiliating treatment program—all for trying to live honestly in a society that defined homosexuality as a crime.The inspiration for a major motion picture starring Benedict Cumberbatch and Keira Knightley, Alan Turing: The Enigma is a gripping story of mathematics, computers, cryptography, and homosexual persecution.

The Albert Einstein Collection Volume Two: Essays in Science, Letters to Solovine, and Letters on Wave Mechanics
by Albert EinsteinFrom revealing, personal letters to brilliant essays on the nature of science, these three volumes demonstrate the breadth of Einstein&’s thought. The man who became famous for conceiving of the equation E=mc2 kept his mind sharp through stimulating correspondence and applied his intellectual acuity to a number of important scientific issues. The second volume of the Albert Einstein Collection offers a fascinating window into how he developed his ideas. Essays in Science: In these sixteen essays, written at the height of his intellectual powers, Einstein sets out his views on scientific knowledge, its relationship to human experience, and the underlying principles of any scientific pursuit. He discusses his own work in theoretical physics and its basis in field theory, as well as the many achievements of other scientific thinkers—including Johannes Kepler, Isaac Newton, James Clerk Maxwell, Max Planck, Niels Bohr, and others. Letters to Solovine: This collection of personal letters from Einstein to his longtime friend and translator Maurice Solovine offers a rare glimpse into the evolution of his thought, as well as a revealing portrait of the man himself. Spanning Einstein&’s career and ranging from philosophical discussion to personal gossip, these letters are presented in English translation alongside the German text, with facsimiles of the original letters also included. Letters on Wave Mechanics: In this stirring collection of correspondence, four of the twentieth century&’s greatest minds—H. A. Lorentz, Max Planck, Erwin Schrödinger, and Albert Einstein—discuss, debate, and refine Schrödinger&’s then-nascent theory of wave mechanics. As the physicist Karl Przibram states in his foreword to this edition, &“little needs to be added to the letters; they speak for themselves. Apart from their essential content, they reveal something of the personalities of the four men of genius.&”
Albert Einstein, The Human Side: Glimpses from His Archives
by Albert EinsteinModesty, humor, compassion, and wisdom are the traits most evident in this illuminating selection of personal papers from the Albert Einstein Archives. The illustrious physicist wrote as thoughtfully to an Ohio fifth-grader, distressed by her discovery that scientists classify humans as animals, as to a Colorado banker who asked whether Einstein believed in a personal God. Witty rhymes, an exchange with Queen Elizabeth of Belgium about fine music, and expressions of his devotion to Zionism are but some of the highlights found in this warm and enriching book.
Albert Einstein, Mileva Maric: The Love Letters
by Albert EinsteinIn 1903, despite the vehement objections of his parents, Albert Einstein married Mileva Maric, the companion, colleague, and confidante whose influence on his most creative years has given rise to much speculation. Beginning in 1897, after Einstein and Maric met as students at the Swiss Federal Polytechnic, and ending shortly after their marriage, these fifty-four love letters offer a rare glimpse into Einstein's relationship with his first wife while shedding light on his intellectual development in the period before the annus mirabilis of 1905. Unlike the picture of Einstein the lone, isolated thinker of Princeton, he appears here both as the burgeoning enfant terrible of science and as an amorous young man beset, along with his fiance, by financial and personal struggles--among them the illegitimate birth of their daughter, whose existence is known only by these letters. Describing his conflicts with professors and other scientists, his arguments with his mother over Maric, and his difficulty obtaining an academic position after graduation, the letters enable us to reconstruct the youthful Einstein with an unprecedented immediacy. His love for Maric, whom he describes as "a creature who is my equal, and who is as strong and independent as I am," brings forth his serious as well as playful, often theatrical nature. After their marriage, however, Maric becomes less his intellectual companion, and, failing to acquire a teaching certificate, she subordinates her professional goals to his. In the final letters Einstein has obtained a position at the Swiss Patent Office and mentions their daughter one last time to his wife in Hungary, where she is assumed to have placed the girl in the care of relatives. Informative, entertaining, and often very moving, this collection of letters captures for scientists and general readers alike a little known yet crucial period in Einstein's life.
Albert Einstein: pocket GIANTS
by Andrew MayEveryone has heard of Albert Einstein and everyone knows that he was a genius. Yet only a few people understand his work. In fact, he was just one of many brilliant scientists grappling with the deepest problems of theoretical physics during the first half of the twentieth century. He may not have been the most important or influential of them – the point is arguable – but there is no doubt he was the most revolutionary. Almost single-handed, he transformed the way the world thinks about light, matter, space and time.In the sixty years since his death Einstein has become a legend. The profound obscurity of his theories has contributed to this, as has his archetypal “mad scientist” appearance. His philosophical and political utterances – both real and imagined – are regularly used to clinch arguments online or in the pub. So how can a modern reader separate myth from reality? This short book attempts to do just that!
Albert Einstein (Rebel Lives)
by Albert Einstein Tom KeebleEinstein as an absent-minded genius with his head in the clouds is a far cry from the real picture. A man deeply interested in social issues, Einstein felt it was his duty to use his fame and intellect to advance the cause of social justice.
