Structural change

In economics, structural change is a shift or change in the basic ways a market or economy functions or operates. Such change can be caused by such factors as economic development, global shifts in capital and labor, changes in resource availability due to war or natural disaster or discovery or depletion of natural resources, or a change in political system. For example, a subsistence economy may be transformed into a manufacturing economy, or a regulated mixed economy may be liberalized. A current driver of structural change in the world economy is globalization. Structural change is pos ...

                                               

Chemical change

Chemical changes occur when a substance combines with another to form a new substance, called chemical synthesis or, alternatively, chemical decomposition into two or more different substances. These processes are called chemical reactions and, in general, are not reversible except by further chemical reactions. Some reactions produce heat and are called exothermic reactions and others may require heat to enable the reaction to occur, which are called endothermic reactions. Understanding chemical changes is a major part of the science of chemistry. When chemical reactions occur, the atoms ...

                                               

Chemical reaction

A chemical reaction is a process that leads to the chemical transformation of one set of chemical substances to another. Classically, chemical reactions encompass changes that only involve the positions of electrons in the forming and breaking of chemical bonds between atoms, with no change to the nuclei, and can often be described by a chemical equation. Nuclear chemistry is a sub-discipline of chemistry that involves the chemical reactions of unstable and radioactive elements where both electronic and nuclear changes can occur. The substance or substances initially involved in a chemical ...

                                               

Damage

Damage is any change in a thing, often a physical object, that degrades it away from its initial state. It can broadly be defined as "changes introduced into a system that adversely affect its current or future performance". Damage "does not necessarily imply total loss of system functionality, but rather that the system is no longer operating in its optimal manner". Damage to physical objects is "the progressive physical process by which they break", and includes mechanical stress that weakens a structure, even if this is not visible.

                                               

Instantaneous rate of change

The derivative of a function of a real variable measures the sensitivity to change of the function value with respect to a change in its argument. Derivatives are a fundamental tool of calculus. For example, the derivative of the position of a moving object with respect to time is the objects velocity: this measures how quickly the position of the object changes when time advances. The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of the function at that point. The tangent line is the best linear approxi ...

                                               

Impermanence

Impermanence, also known as the philosophical problem of change, is a philosophical concept that is addressed in a variety of religions and philosophies.
