As a means of better understanding applied mathematics, the following text describes the fundamental properties of this discipline. In essence, applied mathematics is a theoretical science that allows for the construction of mathematical models that have been created to accurately represent complex real-world phenomena. They are usually employed to solve practical problems in engineering or natural resources management. The need for the use of these models arises from an inability to obtain all desired information about a real-world system or phenomenon through traditional empirical methods (i.e., via experimentation). This is due largely to inherent limitations in measurement and observation techniques as well as ethical considerations associated with exposing human subjects to potentially hazardous situations (e.g., medical trials). Thus, mathematical models are needed to simulate complex systems in order to gain necessary information. Although oversimplified, the most common applications of applied mathematics include the following: If applied to systems that involve differential or differential-algebraic equations (i.e., systems that involve functions of two or more unknowns), then it is referred to as multivariable mathematics. Applied mathematics often arises from the need for application-specific solutions, which may not always be straightforward in nature. The application engineer/scientist must decide how much "baggage" is acceptable in their design problems. An example of a simple application of mathematics is Newton's law of cooling, which states that the rate at which a body loses heat is proportional to the difference between its temperature and the ambient temperature. In this case, ambient temperature is considered a constant and can be omitted from the equation. More complex problems may require an understanding of time-dependent phenomena, such as heat diffusion through solids, wherein it becomes necessary to account for the fact that heat diffuses more quickly in some materials than others. Such considerations would necessitate a sophisticated mathematical model capable of incorporating material properties into solution. Some analyses have no real practical application because they are too complex or expensive to solve, even if they can be experimentally verified with relative ease. These questions are sometimes called "science fiction", although they may be realistic. This is because they are often far outside the range of what is possible in practice, but this does not mean that the mathematical models devised to describe them cannot be useful or useful for other purposes. Since applied mathematics deals with real-world problems, it must consider the practical aspects of these problems in order to ensure that solutions are efficient and cost effective. Some form of data must be collected. This information may relate to time, temperature, pressure (e.g., barometric pressure), weight (e.g., mass or volume), or other physical properties (e.g., flow rate). Data collection may be performed frequently, often an hourly to daily basis. Data are recorded in computerized data logs, which are updated to reflect changes in the status of the systems. For example, if a power line is subject to failure or other problems, it would be important for the utility company to know if the pressure has dropped below its allowable threshold. A mathematical model can describe a system accurately because it may be based on mathematical relationships that are known with some degree of certainty ("certainty limits"). An example of this is heat transfer through material during temperature change. Since heat diffuses more easily through metals than plastics, metals are used as heat transfer mediums in high-heat applications. cfa1e77820
