Systems simulated by a simple percolation model using python I'm a first year physics student, and one of my assignment for my programming class is about percolation I need to create some disks randomly distributed in an area (this is a 2-D), and then by varying the density of the disk, I need to figure out the percolation threshold such that the two sides of the square area is connected by the clusters
First law of this universe - Physics Forums While studying certain aspects of physics, chemistry, biology, and psychology, I noticed that everything follows a single "law": energy always moves along the path of least resistance least effort I observe this law in evolution, in every living organism, in every thought and decision, in
What happens to the carbon in rotting grasses? - Physics Forums So, the penetration of fixed carbon from the duff layer into soils is small because there isn't much leftover, and it doesn't have anything other than percolation or surficial insect activity to embed the remaining carbon down in the soil In bog conditions, arctic conditions and wherever else those little guys don't live there is no chewing
Difference between absorption and scattering cross sections Hi I'm trying to model the attenuation (extinction) of a weak laser through a gas sample using the Beer-Lambert law I've found that the attenuation cross section can be written as the sum of both a scattering and absorption cross section, however I'm having difficulty finding a source that
