This book introduces the fundamental principles of solving partial differential equations (PDEs) using finite difference methods, tailored for practitioners. It focuses on the practical aspects of numerical methods, including the design of finite difference schemes, the creation and execution of algorithms, the validation of these implementations, and the interpretation of numerical results to understand physical phenomena, with applications in physics and biology.

This book is presented as an accessible introduction to finite difference methods for solving PDEs, specifically designed for practitioners rather than academics. The approach emphasizes practical implementation and application, suggesting a focus on hands-on learning and real-world problem-solving in scientific fields. The open-access nature under a CC BY 4.0 license indicates a commitment to broad dissemination of knowledge.
