I started a new book to explain non-Nashian #gametheory and how Einstein may have been right on #quantum theory. To help spread the word, it will remain freely available online. non-nashian-game-theory.org/ #determinism #superrationality #causality #locality #contextuality

Ghislain Fourny from the Department of Computer Science is known for his #hybridteaching and for inlaying his slides on a green screen, akin to a weather forecast. If you’ve ever wondered what this looks like, check out the video: bit.ly/48yAlET @ETH_en #teaching

Support for JSON updates (following the XQuery Update Facility) including the copy-modify-return expression is now in the RumbleDB master branch!

Oh, and did I mention it supports read and write access to the Delta Lake?

Recording of my 2023 talk on how: - to see #quantum theory as a chess game between physicists and the universe, - Nash equilibria are constrained by impossibility theorems, - relaxing free choice brings back determinism and could prove Einstein right. youtube.com/watch?v=63qLkMAb…

Data independence is crucial to shield users from complexity, says Ghislain Fourny. We're live at Data Amplified discussing how to scale up the storage and management of #XBRL data for the age of big data. #DA2023

🎉Delighted to announce that our first "non-Nashian quantum theory" paper, co-authored with Michael Baczyk at ETH Zürich, was just published in Springer Nature's Quantum Studies: Mathematics and Foundations, and it is publicly available via Open Access! link.springer.com/article/10…

👉 The model presented in the paper is general enough (e.g., the payoffs are left open) to be instantiable into falsifiable theories that predict individual measurement results -- hopefully leading to real-life experiments at some point in the future!

This builds on 20 years of work on non-Nashian game theory, yet this is just the beginning of a fascinating new avenue of research.

A very accessible talk by Ghislain on whether we need an assumption of free choice for quantum mechanics to make sense.
