... It is hardly surprising, then, that the singular physics adventurer Bob Coecke—who, among other things, built a quantum .guitar (and even performed with it before heavy metal fans)—is now applying his physics-inspired mathematical expertise to the understanding of textual structures."

"Anyone wishing to join this discussion must engage with a dynamic interplay of distinctions, comparisons, and inferences drawn from premises—all of which require precise linguistic articulation. Rarely have there been problems that have so powerfully intertwined physics and language ...

Here's Relational Intelligence. rel-int.ai Why? Current LLMs are unexplainable, no path to efficiency, no path to scalability... How? The same structure governs quantum mechanics and natural language, and cognition more generally. We use this to build AI whose reasoning you can trust. When? Now!

Finally got my hands on the Greek copy of Quantum in Pictures. Very proud of that, as there is the pre-Socratic connection. It is beautifully done.

The world needs opposites to get along, work together...music is a good way to do so.

Industrial electronics and classical piano on the same stage at the Holywell Music Room, one of the oldest concert venues in Europe. Rakhat-Bi Abdyssagin, Bob Coecke and Bruce Warner closed out the Oxford Quantum Centenary Conference. qspace.fqxi.org/videos/566/i...

Short news bite on Quantum Guitar by FQxI.

A brand new instrument called the “quantum guitar” performed alongside one of the oldest instruments, the organ, at one of the most beautiful chapels in Oxford. Rakhat-Bi Abdyssagin and Bob Coecke performed Abdyssagin’s ‘Quantum Universe’ at Merton College. @coecke.bsky.social

...not just in terms of making things accessible to the younger, but also more broadly an inclusive societal paradigm, combatting things like racial profiling and (Western-style-)learning difficulties, all of which is rooted in Aristotelian style reasoning, on which society is still very much build

In Palermo for 3rd Int. Symp. on Quantum Computing & Musical Creativity, where I will do a Quantum Guitar demo, present a paper on it, and also present the paper with Rakhat-Bi Abdyssagin on a new music notation based on ZX-calculus, which we call Quantum Concept Music. 2025.isqcmc.org/program.html
