Liesegang Rings
A researcher explores the physics of self-organizing phenomena, specifically focusing on Liesegang rings and convection cells. The author aims to understand how complex patterns emerge from simple chemical and physical variables.
Why it matters
Understanding these non-equilibrium systems provides insights into biological patterning and fundamental physics that can be replicated in a laboratory setting.
7 1 1 Share Last time I write about trying to find phenomena where the physics might stay the same as you shrink down the dimensions . Another one of the themes of the independent science society is to figure out how to create complex phenomena worth experimenting with on tabletop.
Previously I demonstrated Rayleigh Bernard convection cells with Mica powder and oil, where I saw cell-like devisions in liquid when I applied a temperature gradient. This was an example of non-equilibrium , self organising phenomena due to the application of a temperature gradient. I've preciously tried and failed to do other things like the Briggs Rauscher reaction, which is a (safer) example of an oscillating chemical reaction.
