Angela Collier, Anne L'Huillier and Jacob Barandes on Physics

Angela has done two really great videos in the past week or so:


See Anne L'Huillier's Nobel Prize talk last year, and note the bit at the end about the time-delayed transitions from different shells:


Then the day before yesterday Angela came up with this one about the sorts of physics problems that students learn to solve, and abstracted five Common Notions:

So, instead of revealing unity in the fundamental laws of Nature modern physics is unfolding this enormous complexity in our different ways of describing Her. There might be a reason for this, ...

And I am one and a half hours through this really interesting interview Curt Jaimungal did with Jacob Barandes about his connection between non-Markovian stochastic processes and Quantum Mechanics. He just took a naïve approach and modeled a fundamentally stochastic measurement process which he found was non-Markovian in the sense that the transition distributions between states were not constant, but varied with the internal dynamics of the system. But this dynamical variation turned out to produce "memories" in the evolution of the state-transition distribution and these correspond to what are termed measurements in Quantum Mechanics. So it sounds to me like he has a model of space-time as a partial order of events, and that this ought to work well with the ideas of enactive cognition that Karl Friston talks about. See  Why I Don't Think Reductionism Should Be Part of the Physics "Package", and also Mithuna Yoganathan - Quantum Mechanics Course (and Vandana Shiva on Quantum Thinking) and Mithuna Yoganathan on The True Meaning of Schrodinger's Cat.

... and his posterity too? See  On Communication in Linear Time And Hypertext And The Gospel of Sophia . So it looks like El Cielo of the cistine [sic!😂] chapel is not the limit anymore.  I think I just met one of his descendents. A guy called Versailles Toledo who is from Chiapas. That might explain the murals I mention in my recent untitled post , just before the post mentioning this video. I also just took this photo of Rafael Gonzales, born here in Tecate, B.C., who told me about a spring near here called Agua Fría , half way from Tecate to Loma Tova , where, a few decades ago, people used to go to have barbecues and stuff, but now he thinks it may be private land. If someone reading this has a Facebook account, please write a link to this post onto his FB page. To see why I took the photo, look at his T-shirt and the horse-shoes and ponder this: Subscribe to BeatrizER and her video(s?) about mathematical logic, ...

David Turner Obituary by Sarah Nicholas Fri 24 Nov 2023

This was in The Guardian: David Turner obituary , only eight days after I posted  David Turner Talking About Sixty Years of Functional Programming History : This talk was given in London in 2017: See  Turner, D. A. "Some History of Functional Programming Languages" also  John Hughes - Why Functional Programming Matters  and David MacQueen's talk at ICFP 2015 in  Numberphile - Sophie Maclean on the Catalan Numbers . At 10:30 This whole discussion abut combinator reduction is especially interesting. I didn't know Arthur Norman had tried building hardware for combinator machines. I'll look that up: maybe start here A.C. Norman  Faster combinator reduction using stock hardware  in LFP '88: Proceedings of the 1988 ACM conference on LISP and functional programming. At 26:25 on the ISWIM virtual machine implemented in the PAL compacting garbage collector?! This work Reynolds and others did was at MIT in Masecheusetts and Argonne National Laboratory Illinois. Did
