  abstract  = {This paper examines Alexander von Humboldt's interest in kilns used for firing ceramics and melting glass. This lesser known aspect of Humboldt's activities is related to his work as a Prussian mining officer in the principalities of Ansbach and Bayreuth between 1792 and 1797. In assessments and reports Humboldt commented on furnace designs and discussed the effectiveness of firing auxiliaries for high-temperature processes. He analysed the causes of the failure of burnings and meltings and made suggestions for their improvement. Various alterations that were carried out during repair work on existing furnaces at the ceramic manufactory in Rheinsberg and the porcelain manufactory in Bruckberg were initiated by Humboldt. Furthermore, it is likely that he was a driving force behind the decision to build a two-storey circular kiln at the Royal Porcelain Factory in Berlin. His reports are explained by means of sketches.},

  abstract  = {A potential human footprint on Western Central African rainforests before the Common Era has become the focus of an ongoing controversy. Between 3,000 y ago and 2,000 y ago, regional pollen sequences indicate a replacement of mature rainforests by a forest-savannah mosaic including pioneer trees. Although some studies suggested an anthropogenic influence on this forest fragmentation, current interpretations based on pollen data attribute the "rainforest crisis" to climate change toward a drier, more seasonal climate. A rigorous test of this hypothesis, however, requires climate proxies independent of vegetation changes. Here we resolve this controversy through a continuous 10,500-y record of both vegetation and hydrological changes from Lake Barombi in Southwest Cameroon based on changes in carbon and hydrogen isotope compositions of plant waxes. delta C-13-inferred vegetation changes confirm a prominent and abrupt appearance of C-4 plants in the Lake Barombi catchment, at 2,600 calendar years before AD 1950 (cal y BP), followed by an equally sudden return to rainforest vegetation at 2,020 cal y BP. delta D values from the same plant wax compounds, however, show no simultaneous hydrological change. Based on the combination of these data with a comprehensive regional archaeological database we provide evidence that humans triggered the rainforest fragmentation 2,600 y ago. Our findings suggest that technological developments, including agricultural practices and iron metallurgy, possibly related to the large-scale Bantu expansion, significantly impacted the ecosystems before the Common Era.},

Kant claims that this was the highest waterfall in the world, which is not true. Alexander von Humboldt could not know anything about it, but he visited the Salto in 1801, just before the publication of Kant's Physical Geography, and went to personally measure the height of the Salto. In this paper we make a comparison of both personalities who, unknowingly, were united by their interest in the Salto de Tequendama.},
