Winter creates many unique patterns. I have to catch them now because they will disappear soon.
Some patterns are easy to explain, but others raise questions.
2) Mandelbrot set - ice - this is my attempt at an explanation
3) Koch curve - salt
4) Diffusion-limited aggregation (DLA) - salt - this is a well researched process
5) Fractal landscape - ice floes on the river
6) Fractal landscape - snow - I wonder - this looks so very much like a real archipelago landscape - maybe the erosion processes are similar in a real landscape and in snow on the sidewalk - is the water erosion process similar to the process caused by walking feet?

The "snow landscape" example probably is an interaction of:
ReplyDelete1) a homogenous layer of snow
2) random perturbation by footsteps
3) feedback powered self-organisation - places with steep angles will erode more quickly when people step on them - probably snow melts faster near the dark pavement
I'm sure you can model that very nicely using 2-d differential equations.

Interesting pics!
ReplyDeleteI am not capable of the Dif EQ math equation. The math for Brownian motion eludes me too. I just recognize them when I see em; I do love patterns and observing natural phenomena. The colour palettes of ice landscapes are strikingly lonely and peculiar. The colours (especially the background)often appear to be predominantly muted mauves,teals,grays an hazy yellows. Look at various depictions Monet's did of Ice floes. The colours are very similar to the ones you captured
P.S.
I don't know much about colour theory either.

Hi
ReplyDeleteI love these pictures. I've enjoyed your blog for a long time too. So much so that I've featured it on my new blog, Psychogeographic Review, as my psychogeographic 'website of the month'!
Why not have a look? It's at:

With best wishes,

ReplyDeleteA very interesting website indeed. It's a mystery how I've managed not to find it yet. I've immediately subscribed myself.
