Molecular diffusionMolecular diffusion is the motion of atoms, molecules, or other particles of a gas or liquid at temperatures above absolute zero. The rate of this movement is a function of temperature, viscosity of the fluid, size and density (or their product, mass) of the particles. This type of diffusion explains the net flux of molecules from a region of higher concentration to one of lower concentration.
Chemical potentialIn thermodynamics, the chemical potential of a species is the energy that can be absorbed or released due to a change of the particle number of the given species, e.g. in a chemical reaction or phase transition. The chemical potential of a species in a mixture is defined as the rate of change of free energy of a thermodynamic system with respect to the change in the number of atoms or molecules of the species that are added to the system.
Stochastic processCollection of random variablesA computer-simulated realization of a Wiener or Brownian motion process on the surface of a sphere. The Wiener process is widely considered the most studied and central stochastic process in probability theory.In probability theory and related fields a stochastic () or random process is a mathematical object usually defined as a family of random variables in a probability space, where the index of the family often has the interpretation of time.
ConcentrationIn chemistry, concentration is the abundance of a constituent divided by the total volume of a mixture. Several types of mathematical description can be distinguished: mass concentration, molar concentration, number concentration, and volume concentration. The concentration can refer to any kind of chemical mixture, but most frequently refers to solutes and solvents in solutions.
Spinodal decompositionMicrostructural evolution under the Cahn–Hilliard equation, demonstrating distinctive coarsening and phase separation.Spinodal decomposition is a mechanism by which a single thermodynamic phase spontaneously separates into two phases (without nucleation). Decomposition occurs when there is no thermodynamic barrier to phase separation.
Probability theoryProbability theory or probability calculus is the branch of mathematics concerned with probability. Although there are several different probability interpretations, probability theory treats the concept in a rigorous mathematical manner by expressing it through a set of axioms.
ChemistryScientific study of matter's behavior and propertiesImages relating to the six main branches of chemistry, clockwise from the upper left : a BeF₂ glass network (inorganic chemistry), a caffeine molecule (organic chemistry), a reaction coordinate diagram (physical chemistry), a proton NMR spectrum (analytical chemistry), the RGS4 protein (biochemistry), and a glowstick using chemiluminescence (applied chemistry).Chemistry is the scientific study of the properties and behavior of matter.
Information theoryScientific study of digital informationInformation theory is the mathematical study of the quantification, storage, and communication of a particular type of mathematically defined information. The field was established and formalized by Claude Shannon in the 1940s, though early contributions were made in the 1920s through the works of Harry Nyquist and Ralph Hartley.
StatisticsStudy of collection and analysis of dataThe normal distribution, a very common probability density, is used extensively in inferential statistics.Scatter plots and line charts are used in descriptive statistics to show the observed relationships between different variables, here using the Iris flower data set.Statistics (from German: Statistik, orig.
Gibbs free energyType of thermodynamic potentialFinanceFinance refers to the management, movement, investment, and raising of money. "Finance" also refers to the academic discipline that studies these. Based on the scope of financial activities, the discipline can be divided into the three primary branches personal, corporate, and public finance.PhysicsPhysics is the scientific study of matter, its fundamental constituents, its motion and behavior through space and time, and the related entities of energy and force. It is one of the most fundamental scientific disciplines. A scientist who specializes in the field of physics is called a physicist. Physics is one of the oldest academic disciplines.
MarketingMarketing is the act of acquiring, satisfying and retaining customers. It is one of the primary components of business management and commerce. Marketing is usually conducted by the seller, typically a retailer or manufacturer. Products can be marketed to other businesses (B2B) or directly to consumers (B2C). Sometimes tasks are contracted to dedicated marketing firms, like a media, market research, or advertising agency.
