I'm 2 semesters from a chem degree... So I enjoy science.
I'm gonna start helping my professor redesign an EEM fluoro spectrometer. We're gonna redo the table top unit, then see if we can stuff it in a tube and throw it in a lake. Not even kidding, they used to have something similar operating in a lake. But the instrument needs to be redesigned, then recalibrated, which is going to be interesting.
Also I'm taking a class on quantum mechanics as related to chemistry. Should be fun and mathematical.
