The book analyses from a comparative perspective the exploration of territories, the histories of their inhabitants, and local natural environments during the long eighteenth century. The eleven chapters look at European science at home and abroad as well as at global scientific practices and the involvement of a great variety of local actors in the processes of mapping and recording. Dealing with landlocked territories with no colonies (like Switzerland) and places embedded in colonial networks, the book reveals multifarious entanglements connecting these territories. Contributors are: Sarah Baumgartner, Simona Boscani Leoni, Stefanie Ganger, Meike Knittel, Francesco Luzzini, Jon Mathieu, Barbara Orland, Irina Podgorny, Chetan Singh, and Martin Stuber.

Elucidates the fundamental mathematical structures of inverse problems, analyzing both the information content and the solution of some inverse problems in which the information content of the coefficients and the source term of a given differential equation is not too large.

Relics of the Past tells the story of antiquities collecting, antiquarianism, and archaeology in Peru and Chile in the second half of the nineteenth and the early twentieth century. While the role of foreign travellers and scholars dedicated to the study of South America's pre-Columbian past is well documented, historians have largely overlooked the knowledge gathered and the collections formed among collectors of antiquities, antiquaries, and archaeologists born or living in South America during this period. The landed gentry, the clergy, and an urban bourgeoisie of doctors, engineers, and military officials put antiquities on display in their private mansions or bestowed them upon the public museums that were being formed by municipalities and governments in Santiago de Chile, Cuzco, or Lima. Men, and some few women, gathered antiquities on their journeys 'inland' and during sociable weekend excursions, but also on quotidian commercial voyages or in military campaigns. They bartered antiquities with their fellow collectors or haggled about their price on the antiquities market. In their hours of leisure, they marvelled at them, wrote about them, and disputed over their meaning, age, and interest in learned societies, informal gatherings, and at meetings in universities and public museums. This volume unveils a hitherto largely unknown world of antiquarian and archaeological collecting and learning in Peru and Chile.

Stefanie Ganger explores how medical knowledge was shared across societies tied to the Atlantic World between 1751 and 1820. Centred on Peruvian bark or cinchona, Ganger shows how that remedy and knowledge about its consumption - formulae for bittersweet, 'aromatic' wines, narratives about its discovery or beliefs in its ability to prevent fevers - were understood by men and women in varied contexts. These included Peruvian academies and Scottish households, Louisiana plantations and Moroccan court pharmacies alike. This study in plant trade, therapeutic exchange, and epistemic brokerage shows how knowledge weaves itself into the fabric of everyday medical practice in different places.

Das Gebiet der elektrischen Gasentladungen ist in den letzten Jahr- zehnten verschiedentlich in Buchveroeffentlichungen behandelt worden. Fast durchweg sind dies zusammenfassende Darstellungen, in denen ausser den zum Zunden fuhrenden Prozessen auch die Vorgange in den hieran anschliessenden stationaren Entladungen behandelt werden. Nur zwei Autoren beschranken sich auf die instabilen Vorgange beim ubergang von der praktischen Nichtleitung von Gasen zur wesentlich hoeheren Leitfahigkeit beim Zunden. Es sind dies W. O. SOHUMANN mit seinem bekannten Werk: Elektrische Durchbruchfeldstarke von Gasen, und L. B. LOEB: Fundamental Processes of Electrical Discharge in Gases. Wahrend nahezu alle Bucher uber Gasentladungen von Phy- sikern unter besonderer Betonung der Elementarvorgii, nge geschrieben wurden, bringt allein das SOHuMANNsche Buch die den Hochspannungs- techniker und Gasentladungsphysiker gleicherweise interessierenden technischen Angaben und Zahlenwerte uber die Vorgange beim Durch- schlag einer Gasstrecke. Das Buch von SCHUMANN ist vor drei Jahrzehnten erschienen. In der Zwischenzeit war es das Bestreben Vieler, den Umfang der Er- fahrungstatsachen zu erweitern und damit gleichzeitig unsere Vor- stellungen vom Durchschlagvorgang zu vertiefen. Eine Flut wissen- schaftlicher Veroeffentlichungen berichtet uber eine fast unubersehbare Menge von Forschungsergebnissen spezieller Art. Wohl nur der un- mittelbar damit Befasste konnte sich durch unausgesetztes Studium des periodisch erscheinenden Fachschrifttums auf dem laufenden halten.
