Former Fellow

Jim Ritter

Prof. Dr. Jim Ritter (Institut de Mathématiques de Jussieu-Paris Rive Gauche, Sorbonne Université, CNRS; Equipe: Histoire des Sciences Mathématiques) is a historian of science. His research focuses on the history of rational practices in ancient Egypt and Mesopotamia and on the history of general relativity and unified theories.

Research project title:
Algorithmic knowledge in Egypt and Mesopotamia

Research abstract:
This project aims to construct a database for ancient Egyptian and Mesopotamian mathematical problem texts, as a tool for the further development of an algorithmic approach to the study of such corpora; an approach initiated by Jim Ritter and further developed in collaboration with Annette Imhausen. The algorithmic approach, which by means of a linguistic and logical analysis of the solution algorithms represented by several hundred Mesopotamian and Egyptian examples, lends itself particularly well to a systematic approach to the full collection of texts, permitting searches for patterning in sequences of operators both within a given corpus and between corpora; hence the interest in a full database with both linguistic and mathematical information.

Das Prinzip Donald Trump und die Verrohung der Welt

Panel Discussion, Lecture

Ein neuer Politikstil macht international Karriere. Er ist gekennzeichnet von Vulgarität, Verrohung und erklärter Rechtsfeindschaft. Machtinteressen werden nicht mehr juristisch bemäntelt. Stattdessen wird das angebliche Recht des Stärkeren zur Staatsdoktrin gemacht – innenpolitisch wie außenpolitisch. Treibende Kraft hinter dieser Verrohung der politischen Sitten ist ein US-Präsident, der nicht nur die amerikanische Gesellschaft und Kultur, sondern auch die globale Ordnung nach seinen Vorstellungen und Interessen umgestaltet. Die Römerberggespräche wollen diesen Politikstil verstehen.

40 Jahre Schengen-Raum

Colloquium

Der 1984 geschlossene Schengen-Vertrag schuf einen heute 29 Staaten umfassenden Raum ohne Binnengrenzen, doch Migration über die Außengrenzen führte zuletzt zur Wiedereinführung von Kontrollen, auch durch die Bundesregierung ab 8. Mai 2025. Das Walter Hallstein-Kolloquium diskutiert die rechtliche Zulässigkeit, wirtschaftliche Folgen insbesondere für Arbeitsmigration und Arbeitsmarkt sowie die Zukunft des Schengen-Raums.
