Code for Thought

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).

English Edition: NextBrain is a next generation atlas of the human brain. Juan Eugenio Iglesias Gonzales from Massachusetts General in Boston, US, has been leading this project. My colleague James Hughes (University College London) and I were working on part of it at the time. And in this episode we explore, once again, what NextBrain is, how it evolved using AI tools in a shifting technology landscape and how it can be used in education and research.

English Edition: Meet Thomas White from DESY (German Electron Synchrotron) who is the creator and maintainer of the tool CrystFEL. The tool to help understand and analyse the structure of materials such as crystals and proteins. Thomas and I dive into the details of the science and experimental setup - and, of course, the software tool he created.
