Taken from the wonderful new webpage globalinequality.org, here is the picture that my dear European politicians and their supporters have to explain me in view of the next militarization wave. 3x more military spending? No, thank you!

www.sufficiencywellbeing.com/p/the-myth-o... Studies, such as a report from The Nature of Americans, reveal that people often experience nature as a concept rather than a relationship. Many believe that "real" nature requires travel, gear, or leisure time.

Pure insanity! The NATO just decided, in a most undemocratic way without asking the population or revealing any details, to extremely increase their military spending. 🤬🤬🤬 Because having spent for decades over 50% of the worlds military budget for 10% of the worlds population is clearly not enough.

Very happy that the (maybe) first (?) paper systematically investigating the difference of decoherence between chaotic and integrable systems made it into PRL. 🤗 Surprisingly (?), and similar to thermalization, decoherence robustly happens only in chaotic systems! journals.aps.org/prl/abstract...

Just read a nice interview from @fqxi.org about a journal that introduced "post-publication peer review". Love it. But deer FQxI, do your homework: peer review is not established since "centuries". 😣 It's a recent thing! Nature introduced peer review only in 1973! qspace.fqxi.org/articles/272...

Fantastic new paper by Schindler et al. generalizing the notion of "observational" entropy. I've previously claimed obs. entropy is just the right way to think about "entropy" physics, as it encompasses/unifies many other versions. This is the even more right way. arxiv.org/pdf/2503.15612.

Happy that this paper arxiv.org/abs/2503.15612 made it over the finishing line after years of drafting. :) In short, Shannon/von Neumann/canonical/surface/volume/entanglement/diagonal/etc. entropies are all the same, they just differ with respect to the reference prior and measurements you choose.

Does emergence exist? Is it a useful concept? Liam Graham argues in his new interesting book "Physics Fixes All the Facts" (link.springer.com/book/10.1007...) that we are better off abandoning "emergence". I discuss with him on my blog why. Check it out at boltzmannsbrain.blog/dialogue-wit...

When the US ruling class says that something poses a threat to the "American way of life", what they actually mean is it poses a threat to the interests of US capital accumulation.

Hello community. Using my first post here for some shameless self-advertising of a cute little paper (arxiv.org/abs/2412.08444) explaining subtleties and pitfalls of decoherence and the emergence of classicality. Best read in front of a chimney. 😉
