Discaimer: I think it is.
Anyway. My girlfriend takes the XKCD stance, whereby she claims that mathematics and physics are the only 'true' sciences, and that all aspects of biology are more akin to an art. Strangely, she seems to think that genetics is exempt, but things like ecology and taxonomy definitely do not fall within the realm of science.
She thinks the same applies to psychology and sociology, though I'd be inclined to agree sometimes, given that those subjects don't deal with phenomena that are immediately or easily quantifiable.
I agree insofar as all biology has a chemical basis, and all chemistry has a physical basis, but still. The systematic study of any phenomena, to me, is a science. We could study anatomy in terms of physics [biophysics dabbles with this], but it seems inherently ridiculous to discredit an entire branch of science because it uses a different set of vocabulary.
Thoughts?
EDIT: Be civilized. I don't appreciate anybody being called an idiot, much less somebody I'm close to. I was asking for an opinion regards this specific question, not my choice of partner.
