Code for Thought

English Edition: In this ByteSized episode & online class we're talking about GitHub Pages and how it can help you to create a web-site for your research project (reasonably) quickly. With me are Sarah Gibson and Jeremy Cohen. 

I'd like to thank the UK STEP-UP project and Imperial College London for supporting this show.

English Edition: there is a (relatively) new kid on the block - of open source package managers. It's called Pixi: and in this episode I talk to Raniere de Silva (GESIS) and Wolf Vollprecht (Prefix - the company behind Pixi), what the tool brings to the table.

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).

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.
