Biophysics is an interdisciplinary field that integrates physics, biology, chemistry, engineering, and mathematics to address biological problems. It emphasizes the physical principles underlying biological systems, such as drug diffusion in tissues or cell counting techniques, often requiring collaboration among experts from various scientific backgrounds. For students torn between pursuing physics or biology, starting with a general science program is advisable to explore interests before specializing. Biophysics at the undergraduate level is more mathematically oriented and focuses on the mechanics of biological systems rather than the identification of biological components like proteins or genes. Those interested in neuroscience can apply biophysical methods to model neural networks and brain functions. Ultimately, the choice between biophysics and a broader biology major depends on individual interests in theory versus experimental work.
