## What do you learn in Biophysics

Biophysics explores the intersection of biology and physics, applying physical principles to biological systems. You'll study molecular structures, cellular mechanics, and energy transfer in living organisms. The course covers topics like protein folding, membrane dynamics, neural signaling, and biomechanics. You'll learn to use mathematical models and advanced imaging techniques to analyze complex biological processes at various scales.

## Is Biophysics hard?

Biophysics can be challenging because it combines two complex fields. You'll need a solid foundation in both biology and physics, plus some math skills. The concepts can get pretty abstract, and there's a lot of problem-solving involved. But don't let that scare you off - if you're interested in the subject and willing to put in the work, it's totally manageable. Plus, the hands-on lab work makes things more concrete and fun.
