Let me know if this is the wrong forum. I'm a neurobiology student and I've recently come across more information about biophysics, but from what I've read, it's a little difficult to understand fully how physical principles are applied in the field. For example, there's structural biophysics, systems neuroscience (which is a central topic in my curriculum and which I'm quite familiar with, but have mostly gotten my grounding in the biological aspects of it and not been exposed to much of the physics side of it beyond, say, electrophysiology), molecular microscopy, cell signaling and physiology, computational biology, bioelectronics, and biomechanics, which are some pretty broad fields within not only biophysics but within other fields as well. I can infer to an extent where physics applies - it's much more obvious in systems neuroscience and cell signaling (electrophysiology), but less so in, say, structural biophysics and biomechanics. (Then again, the extent of my physics classes is two semesters of introductory physics, which is the only physics requirement for my degree and is all the physics I can reliably squeeze in to my curriculum, which has a lot of requirements) I have some idea of how physics intersects with all of this, but I want to hear from people who have a better understanding of the physics aspects of this.
