Biophysics!

I just had biophysics... I have always been having problems with physics, I have never understand the meaning with it, never cached how to use all the formulas that looks just as strange signs on a paper. Well, you know what? I am changing my mind, I am starting to really like physics is really fun! It's also because of my teacher, she is a really good teacher, teaches in a way that make me interested of the subject. Today we used the refractometer and measured the index of the centrifuged blood plasma. Here are some pictures!
