The study of applied mathematics and computational sciences deals with the use of mathematical concepts and computational techniques in various fields of science and engineering. It has become an indispensable component of almost every discipline of science, engineering, industry, and technology.

The fundamental concepts and tools of calculus, probability, and linear algebra are essential to modern sciences, from the theories of physics and chemistry that have long been tightly coupled to mathematical ideas, to the collection and analysis of data on complex biological systems. Given the emerging technologies for collecting and sharing large data sets, some familiarity with computational and statistical methods is now also essential for modeling biological and physical systems and interpreting experimental results.

These two courses introduce fundamental concepts of calculus, probability and computational sciences applicable to inquiry across the natural sciences. The sequence could also serve the needs of many social science students. MF1 is an introduction to differential and integral calculus that focuses on the concepts necessary for understanding the meaning of differential equations and their solutions. It includes an introduction to a software package for numerical solution of ordinary differential equations. MF2 is an introduction to probability and statistics with an emphasis on concepts relevant for the analysis of complex data sets. It includes an introduction to the fundamental concepts of matrices, eigenvectors, and eigenvalues. Exercises and problem practices in both MF1 and MF2 include applications in physics, chemistry and biology.

Contemporary investigations in these domains increasingly span multiple disciplines, and the DKU concentrations in natural science will be designed to span essential domains of the traditional fields. This two course sequence addresses the basic principles in an integrated manner, introducing the relevant concepts as needed for interdisciplinary applications. The themes of energy and emergent phenomena are chosen to highlight the connections between the traditional sciences along with the differences in the types of phenomena they seek to describe. Laboratory components of these courses serve tutorial purposes and introduce fundamental concepts in measurement and uncertainty. IS1 examines the fundamental concept of energy and its relevance for understanding the behavior of physical, chemical, and biomolecular systems. The emphasis on energy reflects its central role in physics and technological devices, its importance in determining chemical structures, and its relevance to the function and evolutionary fitness of biological systems. Topics include thermodynamics, mechanical systems, momentum conservation, chemical bonds and reactions, and nuclear energy. IS2 introduces the scientific insights that allow us to understand natural systems with many components, from which coordinated macroscopic phenomena emerge. Topics include natural selection and evolution, fundamentals of molecular biology, and population dynamics. IS1 and IS2 are closely linked to MF1 and MF2, respectively.

These two courses focus on fundamental phenomena relevant for understanding the world of our immediate experience. IS3 emphasizes the physics and chemistry concepts of oscillating systems, waves, and fields, and includes applications to human perception. In addition to their fundamental importance to physics and chemistry proper, these ideas are essential for developing an awareness of the principles employed by engineers in the construction of the electrical and optical devices that are ubiquitous in modern civilization. Topics include harmonic oscillators, sound waves, light, and reaction-diffusion patterns. IS4 has more of a chemistry/biology emphasis, with physics brought to bear as needed. It treats topics relevant to understanding organisms, biochemical engineering, and the environment. Topics include evolution, modern biology, ecosystems, hydrology, and climate. IS3 and IS4, emphasize the multiple connections between physics, biology and chemistry. In this way, these provide an integrated scientific perspective that students can carry forward into their areas of specialization.
