Minister Kolasek mówi o wzroście finansowania nauki i szkolnictwa wyższego o 2.2 procent w kwotach realnych (5.6 procent w kwotach nominalnych) tak: > Możemy mówić o istotnym impulsie rozwojowym dla całej naszej gospodarki Co za kpina - w takim tempie do poziomu europejskiego dojedziemy za 30 lat.

It's easy to grasp that maths education is just "brain gym" and using AI to solve maths problems is like lifting weights with a forklift. You can take solace in that it's all a "brain gym" - elite brain drivers are driving around a track, not driving somewhere. STEM gains are only a nice byproduct.

The "AI solved Navier-Stokes" is such an exaggeration - the paper (which OpenAI might have stolen from a human) describes a particular, exotic, configuration of forces under which fluid velocity blows up.

Adding Poland to the Economist's comparison of reading scores shows where we could've been with a more resilient education system. There are a lot of downward pressures on the learning outcomes (covid, privatisation, AI), but we lost 24 points in a decade - more than one year of schooling!

Compare just how AI-pilled your academic community is (based on the data from Nautre survey N=5229). Seeing physicists in third place, not far from computer science, is not a surprise, but it still makes me sad.

In Poland, whether you are secularised or not determines your voting choices (income much less so). This is either obvious (if you don't remember Poland 25 years ago) or not at all (if you remember JP2-Solidarity synergy). My research based on 25 years of regional data now on socarxiv: osf.io/wud4h

Mehr5,7,8Many animals produce courtship sounds, and receivers prefersome sounds over others. Shared ancestry and convergentevolution may generate similarities in preference across speciesand underlie Darwin’s conjecture that some animals “havenearly the same taste for the beautiful as we have.” In this study,we show that humans share acoustic preferences with a rangeof animals, that the strength of human preferences correlateswith that in other animals, and that humans respond fasterwhen in agreement with animals. Furthermore, we foundgreatest agreement in preference for adorned, ancestral, andlower-frequency sounds. humans’ music listening experiencewas associated with preferences. These results are consistentwith theories arguing that biases in processing sculpt acousticpreferences, and they confirm Darwin’s century-old hunchabout the conservation of aesthetics in nature
