A Nobel Prize winning scientist discovers that the extinction of the dinosaurs was caused by a DNA sequence triggered by global warming sixty million years ago. He now finds that the identical gene in recently extinct and endangered species is becoming active in human beings. He theorizes that current changes in the earth's environment have again triggered the DNA sequence to activity, but is murdered before he can present his findings. While trying to salvage the scientist's research; his assistant and his best friend are hunted across the mountains of western Mongolia by men willing to trade humanity's future for power and money.

Elliptic Tales explores significant advancements in number theory through the lens of the Birch and Swinnerton-Dyer Conjecture, an unsolved problem in mathematics with a $1 million prize from the Clay Mathematics Institute for a general solution. Central to the conjecture are elliptic curves, cubic equations in two variables that, despite their simplicity, stem from profound and often enigmatic mathematical concepts. Authors Ash and Gross make these complex ideas accessible to general readers using basic algebra and calculus, accompanied by numerous enlightening examples. They take readers to the cutting edge of modern mathematics while providing an engaging introduction to key discoveries in algebraic geometry, abstract algebra, and number theory over the last three centuries. The narrative illustrates how mathematics evolves into more abstract realms to address increasingly difficult problems, with each generation of mathematicians building upon the achievements of their predecessors. Ash and Gross clarify how the Birch and Swinnerton-Dyer Conjecture illuminates the number theory of elliptic curves, revealing a beautiful and surprising connection between calculus and algebra derived from these curves.

Das stille Nebeneinander von Zeit- und Umweltgeschichte hat sich in den letzten Jahren in einen beredten Austausch und punktuelle Kooperation gewandelt. Dies ist auf gesellschaftlich wirkmächtige Umweltfragen wie die „Klimakrise“ sowie auf Historiker:innen des 20. Jahrhunderts zurückzuführen, die eng mit der Umweltgeschichte verbunden sind. Die Beiträge in diesem Heft untersuchen das Erkenntnispotenzial eines umwelthistorischen Blicks auf Österreich im 20. Jahrhundert anhand verschiedener Themen: die Ressourcenmobilisierung und die Proteste dagegen im Nationalsozialismus, die Beschleunigung der Material- und Energieflüsse sowie die damit verbundenen Debatten, die durch den Marshall-Plan angestoßen wurden, der gesellschaftliche Naturverbrauch und die mobilisierte Umweltbewegung in den 1970er-Jahren, sowie fotografische Repräsentationen der österreichischen Petro-Moderne.
