Keyword: Biophysics
Introduction
Biophysics is the interdisciplinary science that applies the theories and methods of physics to understand how biological systems work. It explores the mechanics, energy, and structural behavior of living organisms, from single molecules to entire ecosystems.
By blending biology, physics, chemistry, and mathematics, biophysics provides deep insights into the physical basis of life processes such as muscle contraction, nerve signaling, protein folding, and cell movement.
Definition of Biophysics
Biophysics is the study of biological phenomena using physical principles and quantitative methods. It aims to explain how the laws of physics govern the structure and behavior of living organisms.
Unlike traditional biology, which often focuses on qualitative descriptions, biophysics uses measurements, models, and simulations to predict and explain biological functions.
