Biophysics and me

Hmmm . . . Biophysics and me, me as an example of Biophysics. I'm looking over the list of departments that include Biophysics. Some seem very apparent, and others are beyond my current understanding. I don't know what protein folding is, I don't know what phylogenetical analysis is. However, I'm sure that they are wordy complicated explanations of things that occur naturally every day all the time, perhaps in my own body. The introduction we've had into Biophysics seems like a good place to start. What does life need in order to exist. What is life? What is living? How do we decide what fits and what doesn't. None of it seems any more concrete than photons doing whatever they want. It's all how you look at it, whether or not your looking, and who is doing the looking with what methods and instruments.
