Biophysics: Foundations, Problems, and Solutions is an accessible undergraduate text on a wide range of biophysics concepts, examining the field through real problems and their solutions, with comprehensive computation and explanation. With lessons explored over the course of the book, each section also contains a brief theoretical summary of the physics and biology ideas involved, as well as a set of formulae and laws required to answer the issues presented. Intended to serve as the core book for fundamental courses in biophysics and related fields, including biomedical sciences, engineering, and medical technology, the book is also a helpful guide for seasoned experts and researchers who want to improve their knowledge of biophysics or solve related quantitative problems. Biophysics: Foundations, Problems, and Solutions seeks to support readers across several related disciplines in biophysics-focused courses. The book covers a wide range of topics, including fluid mechanics and physics of flow, capillary and surface effects, acoustics, diffusion phenomena and cell membranes, and even radiology and nuclear physics. The book offers a detailed understanding of fundamental principles and dives in-depth into numerical analysis of biophysics problems.
