“… [The authors] analysed one year of drip water monitoring data from 46 monitoring sites across six karst regions in southeastern Australia. By integrating fast Fourier analysis, cross-wavelet transform and change point analysis, [they] identified five characteristic recharge behaviours and developed a conceptual framework linking temporal drip dynamics with recharge mechanisms. [They] hope this framework will contribute to a better understanding of recharge heterogeneity in karst systems and support future groundwater research under a changing climate…”

Mijn nieuwe verhaal voor @nrc_nl, over de wiskunde van Piet Lammers: faseovergangen en percolatietheorie. Een fascinerend snijvlak tussen kansrekening en natuurkunde. In drie dimensies weten we nog maar heel weinig.

I never would expect I see a #Cthulhu -style figure in a #physics #textbook... The figure is not horrifying, but it really looks interestingly funny in the context of a textbook.

The textbook is "Introduction to percolation theory" by Dietrich Stauffer.

#500CharAbstracts: @scschmidt describes here what #percolation analysis is and how it is used to cluster data and create wonderful informative maps. It is a useful approach at very different scales. If you are interested, have a look here. #Archaeology 🏺

I made these using this tiny geometry nodes setup

if your interested in learning more about this sort of thing then look into percolation theory

theres some really interesting stuff out there about the study of randomly connected graphs

and when the pixels are more likely to be connected you end up with one ocean that stretches off into infinity with small islands scattered around

when the probability of pixels being disconnected is higher then the result is much more chaotic, with many small islands and no large ones

I made this by randomly connecting pixels and coloring the contiguous islands

when there is an equal chance that adjacent pixels are connected or disconnected then you get a fractal-esque pattern like this, where islands of all sizes appear

For my latest project, I programmed a visualisation of #percolation in #processing. Percolation is model from statistical #physics most known for exhibiting a phase transition. #creativecoding
