comment Would condensed matter physicists need more than three dimensional calculus?
@NorbertSchuch In my example I have 20 equations (which you can assume are independent) and 20 unknowns. In my hasty mental setup of the problem, I had 10 equations in mind to encode the dynamics, and 10 to encode constraints on the system (e.g. entangled degrees of freedom). A "better" solution might encode constraints by combining variables, but I think my example is sound.

comment Why does the sun make me feel warm?
The impression I got reading this answer is that the majority of heating from sunlight is due to the x-ray portion of the spectrum, which is not the case.

@Keine of course... but not very much.
