- Applied mathematics
**Applied mathematics**is a branch ofmathematics that concerns itself with the mathematical techniques typically used in the application of mathematical knowledge to other domains.**Divisions of applied mathematics**There is no consensus of what the various branches of applied mathematics are. Such categorizations are made difficult by the way mathematics and science change over time, and also by the way universities organize departments, courses, and degrees.

Historically, applied mathematics consisted principally of applied analysis, most notably

differential equations ,approximation theory (broadly construed, to include representations,asymptotic methods, variational methods, andnumerical analysis ), and applied probability. These areas of mathematics were intimately tied to the development ofNewtonian Physics , and in fact the distinction between mathematicians and physicists was not sharply drawn before the mid-19th century. This history left a legacy as well; until the early 20th century subjects such asclassical mechanics were often taught in applied mathematics departments at American universities rather than inphysics departments, andfluid mechanics may still be taught in applied mathematics departments.Today, the term "applied mathematics" is used in a broader sense. It includes the classical areas above, as well as other areas that have become increasingly important in applications. Even fields such as

number theory that are part ofpure mathematics are now important in applications (such ascryptology ), though they are not generally considered to be part of the field of applied mathematics "per se". Sometimes the term "applicable mathematics" is used to distinguish between the traditional field of applied mathematics and the many more areas of mathematics that are applicable to real-world problems.Mathematicians distinguish between applied mathematics, which is concerned with mathematical methods, and applications of mathematics within science and engineering. A biologist using a population model and applying known mathematics would not be "doing" applied mathematics, but rather "using" it. However, nonmathematicians do not usually draw this distinction.

The success of modern numerical mathematical methods and software has led to the emergence of

computational mathematics ,computational science , andcomputational engineering , which usehigh performance computing for the simulation of phenomena and solution of problems in thescience s andengineering . These are often considered interdisciplinary programs.Some mathematicians think that

statistics is a part of applied mathematics. Others think it is a separate discipline. Statisticians in general regard their field as separate from mathematics, and theAmerican Statistical Association has issued a statement to that effectFact|date=April 2007.Mathematical statistics provides thetheorem s and proofs that justify statistical procedures and it is based onprobability theory , which is in turn based onmeasure theory .The line between applied mathematics and specific areas of application is often blurred. Many universities teach mathematical and statistical courses outside of the respective departments, in departments and areas including

business andeconomics ,engineering ,physics ,psychology ,biology ,computer science , andmathematical physics . Sometimes this is due to these areas having their own specialized mathematical dialects. Often this is the result of efforts of those departments to gain more student credit hours and the funds that go with them.POV-statement|date=December 2007**Usefulness of applied mathematics**Historically, mathematics was most important in the

natural sciences andengineering . However, in recent years, fields outside of the physical sciences have spawned the creation of new areas of mathematics, such asgame theory , which grew out of economic considerations, orneural networks , which arose out of the study of the brain inneuroscience , orbioinformatics , from the importance of analyzing large data sets in biology.The advent of the computer has created new applications, both in studying and using the new computer technology itself (

computer science , which usescombinatorics ,formal logic , andlattice theory ), as well as using computers to study problems arising in other areas of science (computational science ), and of course studying the mathematics of computation (numerical analysis ).Statistics is probably the most widespread application of mathematics in thesocial sciences , but other areas of math are proving increasingly useful in these disciplines, especially ineconomics andmanagement science .**tatus in academic departments**Academic institutions are not consistent in the way they group and label courses, programs, and degrees in applied mathematics. At some schools, there is a single mathematics department, whereas others have separate departments for Applied Mathematics and (Pure) Mathematics. It is very common for Statistics departments to be separate at schools with graduate programs, but many undergraduate-only institutions include statistics under the mathematics department.

Many applied mathematics programs (as opposed to departments) consist of primarily cross-listed courses and jointly-appointed faculty in departments representing applications. Some Ph.D. programs in applied mathematics require little or no coursework outside of mathematics, while others require substantial coursework in a specific area of application. In some respects this difference reflects the distinction between "application of mathematics" and "applied mathematics".

Some universities in the UK host departments of "Applied Mathematics and Theoretical Physics", but it is now much less common to have separate departments of pure and applied mathematics. Schools with separate applied mathematics departments range from

Brown University , which has a well-known and large Division of Applied Mathematics that offers degrees through thedoctorate , toSanta Clara University , which offers only theM.S. in applied mathematicsFact|date=February 2008. Research universities dividing their mathematics department into pure and applied sections includeHarvard andMIT .At some universities there is some tension between applied and pure mathematics departments. One reason is that pure mathematics is often perceived as having a higher intellectual standing. Another reason is a different level of compensation, as applied mathematicians are often paid more. Applied mathematics also enjoys better opportunities to bring external funding from many sources, not limited to the [

External funding is highly valued at research universities and is often a condition for faculty advancement. Similar tensions can also exist between statistics and mathematics groups and departments.**See also***
