Physics Through Computation

The book enables readers to develop the ability to translate physical laws into computational models and to analyse systems that do not admit closed form analytical solutions. Emphasis is placed on nonlinear behaviour, coupled systems, and data driven problems that require numerical treatment. The content is organised as a progression from physical formulation to algorithmic representation and implementation. Each topic is introduced through a physical problem, followed by its reformulation into a computational procedure, and implemented using spreadsheets and C programming. This design maintains a consistent connection between physical meaning and computational method.

The primary intention is to establish computation as a central tool in physics, grounded in modelling, approximation, iteration, and interpretation. Numerical methods are presented not as isolated techniques, but as extensions of physical reasoning. Readers gain practical competence in root finding, numerical integration, differential equations, linear systems, and data analysis, along with the ability to evaluate numerical accuracy and uncertainty. The approach supports the development of independent problem solving skills and encourages the use of simulation as a means of investigation. Intended for postgraduate students, the book provides a coherent framework for applying computation to physical systems and for engaging with contemporary scientific problems where analytical methods alone are insufficient.
