comment Combinatorics of the Zeta function of a variety
Qiaochu: I think what hilbert points out is that a closed point is of codimension $>1$.

"what the symbols are meant to mean" may sound a bit defiant, which is not the case and not my intention :-)

comment Intuition behind Matrix Multiplication
@lhf When you extend multiplication to fractions or the real line like you do, I'm sure you agree that the intuitive 'counting' operation of multiplying integers extends to the intuitive operation of 'scaling'.

comment Prove $\mathbb{Z}$ is not a vector space over a field
Nice solution! Getting rid of the simplest (characteristic $2$) case as neatly as possible, and then using this directly to support the initial intuition: "fields have fractions." Om nom chomp.

comment Why is one “$\infty$” number enough for complex numbers?
I see your point of view as well; there are apparently many angles on a somewhat open question. My approach was to point out that the dichotomy between the case of $\mathbb{R}$ and $\mathbb{C}$ implied by the word 'instead' could be considered somewhat artificial o_O

comment Which functor does the projective space represent?
This got way clearer with time. Thanks again :-)

comment Which functor does the projective space represent?
Ah, the condition that the $r_i$ generate $R$ got much clearer when considering that this means that they do not all vanish at any point. This plugs nicely into thinking about projective schemes as looking for strictly non-trivial solutions to homogeneous equations. Neat :-)

comment Which functor does the projective space represent?
Thank you! Another good answer. Hard to know which one to pick, but I think I'll go for this one because it is closer to the generality I asked for. I also found this treated in a set of notes by Strickland on formal schemes.
