Biology applied Inter-disciplinary Pure sciences
Biology applied physics is known as biophysics — an interdisciplinary science that uses the theories, tools, and methods of physics to study biological systems, from molecules to entire organisms. It helps explain how life works at a fundamental level, bridging physics and biology.
🔬 What is Biophysics?
- Definition: Biophysics applies physical principles (mechanics, thermodynamics, electromagnetism, quantum theory) to biological phenomena.
- Scope: It spans molecular biology, cell biology, neuroscience, physiology, and ecology, but with a physics-based lens.
- Goal: To uncover the physical laws governing biological structures and processes.
