Code for Thought

English Edition: preserving digital data has become essential for archives and libraries, as we have seen an explosion of content. I met with various experts in the field who talk to me about the different aspects and facets of saving our data for future generations to come: Thomas Ries (University of Austin, Texas, US), Nanna Bonde Thylstrup and Katie Mackinnon (University of Copenhagen, Denmark), Andy Jackson (Digital Preservation Coalition, UK) and Laurisa Sastoque Pabon (University of Southampton, UK).

Deutsche Ausgabe: In dieser Folge machen wir uns auf die Suche nach dunkler Materie - mit dem ALPS II Experiment am Deutschen Elektron Synchroton in Hamburg. Mit meinen Gästen Axel Lindner und Sven Karstensen tauchen wir in die Welt der Axionen, mysteriöse Teilchen, und wie man sie aufspüren kann. Daneben gibt es, wie immer in der Teilchenphysik, spannende Fragen zu Software und Datenaufarbeitung. Viel Spaß beim Zuhören.

English Edition: how are real numbers e.g. 0.1 represented on computers? What can go wrong with using their representation in calculations? And does it matter? These and other questions are the subject of this ByteSized episode with my guests Prof. Ulrich Ruede (University of Erlangen-Nuernberg), Andreas Herten and Edoardo di Napoli (both Research Centre Juelich).
