Global data set of long-term summertime vertical temperature profiles in 153 lakes

Climate change and other anthropogenic stressors have led to long-term changes in the thermal structure, including surface temperatures, deepwater temperatures, and vertical thermal gradients, in many lakes around the world. Though many studies highlight warming of surface water temperatures in lakes worldwide, less is known about long-term trends in full vertical thermal structure and deepwater temperatures, which have been changing less consistently in both direction and magnitude. Here, we present a globally-expansive data set of summertime in-situ vertical temperature profiles from 153 lakes, with one time series beginning as early as 1894. We also compiled lake geographic, morphometric, and water quality variables that can influence vertical thermal structure through a variety of potential mechanisms in these lakes. These long-term time series of vertical temperature profiles and corresponding lake characteristics serve as valuable data to help understand changes and drivers of lake thermal structure in a time of rapid global and ecological change

Boris Hessen's Manuscripts and Documents on the History of Physics: A Historical Materialist Textbook

The long lost textbook by Soviet scholar Boris Hessen (1893-1936) provides a backdrop for his attempt to develop a historical materialist account of physics as a model for the history of early modern science. It shows that this attempt, signaling the rise of the social history of science, took the complexities of scientific development seriously, in order to provide a deeper understanding of science as such, not only for Marxists. Hessen claims that historical knowledge and its sources provide a rich reservoir, without which science education remains incomplete: No matter how new and unusual the theories of contemporary physics may be, no matter how radically they differ from the outlook of classical physics, the contemporary stage of development in physics is still a historical phase of its overall development. Therefore, knowledge of the history, of the origin, and development of physical theories not only aids in understanding its contemporary condition, but also helps to establish its historical roots and, by doing so, clears the way for new research

Le radici sociali ed economiche della meccanica di Newton

La prima edizione italiana in forma autonoma del celebre intervento di Boris Hessen al Secondo Congresso Internazionale di Storia della Scienza di Londra del 1931 sulle radici sociali ed economiche della meccanica di Isaac Newton. Questo testo \ue8 ormai ritenuto un classico, poich\ue9 rappresenta una tappa fondamentale per gli studi interdisciplinari sulla scienza, sia dal punto di vista storiografico sia da quello metodologico. L\u2019Autore indaga il rapporto d\u2019interconnessione fra il piano economico, i relativi sviluppi tecnologici e le scoperte scientifiche, mostrando la stretta corrispondenza fra le parti di cui si compongono i Philosophiae Naturalis Principia Mathematica di Newton e i nuovi bisogni dell\u2019emergente borghesia inglese
