Diffusion (disambiguation)
Diffusion may refer to: In the physical sciences: • Molecular diffusion (also commonly without additional attributes) spontaneous dispersion of mass (distinct from migration, caused by an external force) • Diffusion of heat • Diffusion of momentum • Diffusion equation - a mathematical formalism describing the spreading of a conserved property caused by its own density gradient • Heat equation • Eddy diffusion In physical sciences, more specific or modified meanings: • Acoustic diffusion of sound waves • Atomic diffusion • Brownian motion, for example of a single particle in a solvent • Collective diffusion, the diffusion of a large number of (possibly interacting) particles • Facilitated diffusion • Effusion of a gas through small holes • Gaseous diffusion • Itō diffusion • Knudsen diffusion of particles from very small containers • Osmosis • Photon diffusion, an optical effect • Diffuse reflection, the reflection of light from an uneven or granular surface • Reverse diffusion • Rotational diffusion • Self-diffusion • Surface diffusion • Thermodiffusion In the social sciences such as sociology, geography, or cultural anthropology: • Diffusion of innovations within a society or a culture or between them • Lexical diffusion within a culture • Trans-cultural diffusion of culture items between cultures • Spatial diffusion of an innovation, an artifact, or populations between and within territories In computer science: • Diffuse reflection, the reflection of light from an uneven or granular surface • Diffusion (cryptography), the spreading of influence of bits in a cipher • Error diffusion in image processing In other areas: • Diffusion (business), the process by which a new idea or new product is accepted by the market • Diffusion process, in probability theory the solution to a stochastic differential equation • Diffusion of responsibility • Society for the Diffusion of Useful Knowledge • The Diffusion Science Radio Show is a science radio show on 2SER in Sydney and podcast • Diffusion Records, an independent record label • Diffusion (7for4 album), a music album by 7for4.
