Bio Project

On Tuesday I have to give a presentation in my bio lab on something to do with enzymes. I have one idea to talk about the theory of the raw food diet because some people believe that the enzymes in raw food will help you to digest food faster. (Of course it's most likely not true from what I'm finding)
Anyway I'm searching for books in the library and this is the title of one of them:
"High-resolution nonlinear multi-photon laser spectroscopy as a diagnostic probe for isotopes and molecules".
Wow. Definitely have no idea what that means!!
