## Applied math does not have any agreed definition. **Lord Rayleigh has given the best explanation of Applied math and as per his view, ‘ Applied mathematics is the procedure of using math to solve the real-world problems by neither seeking nor avoiding mathematical difficulties”**.

The basic use of Applied mathematics includes the different fragments of scientific research, business, Computer Science, as well as Space Science. The basic style of Applied mathematics to work on the practical problems by formulating and studying mathematical models.

Applied mathematics includes traditional areas including Cryptography, Computational Mathematics, Science of Fluid Dynamics, Agronomy, the Study of Topology etc. No definite consensus exists regarding the term of ‘ Applied Mathematics’. For instance, a Biologist uses the population model for studying the field of Population Biology or determination of the Demographic Variations. The various models and calculations which define the different parameters of effective implementation regarding such subjects would have remained incomplete without the help of Applied Mathematics. Some universities

Some universities in the UK have the facilities to study Applied Mathematics as a single subject. For instance, The Department of Applied Mathematics and Theoretical Physics at the University of Cambridge undertakes the study and analytical research regarding the utilisation of the Applied Mathematics. Scientists like Issac Newton, Charles Babbage, Stephen Hawking had worked as the professors.

The disciplines of Quantum Mechanix is one such field of study which requires the application of various theoretical models which are exemplified in the Applied Mathematics

Just like pure math, there are various subfields in applied mathematics, and it would be unreasonable if someone would add it in a single handbook.

**Stargate’sNonlinearDynamics and Chaos is a worth reading book if somebody is interested in Applied math.** The section topology is well-discussed in this book.

Another two books which are useful in imparting the knowledge and understanding regarding the subject under consideration are Methods of applied mathematics by Hildebrand’s and the Advanced calculus for applications. Both of the books are very much affordable by the sense of their applications. Geometrical methods of mathematical physics, Schutz Riemannian Geometry, Lee analysis for applied mathematics, Cheney dynamical systems are some of the books including applied mathematics information. Another segment of Applied Mathematics could be identified as Magneto-Hydrodynamics which is associated with the study of hyper heated plasma, including that of Thermite Plasma. Fusion energy is an example which could be highlighted as an integral part of the study of the Plasma dynamics properties and the entire study deals with the various aspects of ventilation of plasma flows and dynamic oscillation of the many heats exhibited parameters regarding the whole state of Plasma or hyper heated gases.

Mathematical modelling or Topological studies are all directly associated with the mainstream studies of Applied Mathematics. The study and development of an understanding of the Differential models of Calculus and other theoretical constructs associated with it can also be comprehended from an in-depth study of Applied Mathematics.

The combination of knowledge in terms of Mathematical and other scientific theoretical disciplines is always a significant approach concerning the utilisation of such scientific process in various specialised spheres such as those of structural engineering, metallurgy or Astrophysics.

**Applied Mathematics is always associated with the application of the specialised Mathematical formulas and theories in completely transforming or providing the most effective resolution to the existing scientific problems**.

Here lies the fundamental difference between the disciplines of Applied Mathematics and Pure Mathematics. The discourse of Pure Mathematics is always associated with that of the knowledge and development of the understanding of only abstract forms of Mathematical theories. It does not associate itself with that of generation of the solutions for various problems and existing challenges in terms of study and research of various subjective fields. The provision of models and theories in the Applied Mathematics is closely associated with the rectification of such shortcomings in the field of Pure Mathematics.

The Mathematical models which the Applied Mathematical disciplines provide become instrumental for a researcher to utilise in their attempt of delineation of their studies most credible and properly.

From the Utilitarian perspective, the two most significant academic disciplines that have historically relied upon the provision of Mathematical models and theoretical constructs have been Structural Engineering and the Natural Sciences, especially those associated with Physics. With the progression of Science and Time, new spheres of academics such as those of the Statistics, Mathematical Economy and Econometrics have come to rely upon the theoretical and Mathematical models provided by the Applied branch of Mathematics.

The study fields, such as the Game Theory, the sectors related to the development of Information Technology and Computing and Data Processing, also rely considerably on the prospects and theoretical accuracy of Mathematical models provided by Applied Mathematics. Some significant disciplines are Theoretical Computer Science, the Statistical Analysis which deal with subject variables and Numerics and Digitised forms of Algebra.

In this regard, one of the fundamental books that could be focused upon to have a better perspective of Applied Mathematics has been the Introduction to the Foundation of Applied Mathematics, penned by Mark Holmes. Apart from this, the Differential Equations with Applications and Historical Notes peened by George Simmon. These two are some of the most efficacious books which provide the unique insights into the unchartered and less understood theoretical fields which constitute the basis of the Applied Mathematics and the utilisation of the same in various computational sciences, such as the discourses which have been developing in the early years of the 21st century, of which the process of Cloud Based Computing could be identified as a significant one.

The theoretical background which is necessitated by the application of Financial Mathematics requires the obtainment of a sound perception regarding the elemental constituents of the subject of Probability. The working knowledge of the abstract theoretical concepts can only lead one to so far as to have solved the simple problems which do not require any application of the three-dimensional theoretical models that could be only found in the Applied Mathematical traditions. The prospect of applying the theories provided by the financial disciplines of Applied Mathematics in terms of solving the Financial Mathematical problems could only be understood by having assistance from varied sources such as the book Introduction to Probability penned by Grinstead and Snell. This book could provide the appropriate insight which would be necessitated by every student and learner to ascertain the extent of necessary knowledge to determine the various theoretical facets which are provided under the auspices of Probability as a definite subject. Students of social sciences can learn and benefit from such books in the best of the formats.

Providing solutions to Mathematical problems such as those of Linear Algebra, which demands the utilisation of definite forms of models, could be the next form of academic exploration of Applied Mathematics. The book of Linear Algebra With Applications is one of the most effective academic pieces that can provide the necessary insights in this field.This book, authored by Gilbert Strang, provides the necessary range of models and applications that could be utilised by the researchers to outline the various analytical problems that are associated with such fields of applied studies such as Astrophysics and Geophysical science.
