tetthetsfeltet
Tetthetsfeltet, commonly translated as the density field, is a scalar field that assigns to every point in space (and time, when needed) a density value. It is fundamental in many areas of physics and applied science, where density can refer to mass density, material composition, or other conserved quantities that vary spatially.
In mathematics and physics, the density field is denoted ρ(x, t), with units such as kg/m^3 for
Construction and analysis typically involve either measurements or simulations. Observational data from galaxy surveys, seismic imaging,
Applications span cosmology, materials science, geophysics, and medical imaging. Limitations include sensitivity to the chosen smoothing
