I am currently a Maître de Conférences in Saint-Étienne, in France. I am particularly interested in Number Theory and Arithmetic Geometry.

comment Are there some other notions of “curvature” which measure how space curves?
Extremely nice and enlighting answer. Do you have some reference where the whole story is treated the way you present it, or does it come out of your experience (and then: why don't you turn it into a "reference"?).

comment How frequently is 3 a cubic residue mod primes in an arithmetic progression?
Nice, but I do not understand why you chek that $2$, rather than $3$, be a cubic non-residue.

comment Transcendental numbers in the p-adic rationals $\mathbb Q_p$
It seems to me that one way to turn the question into a meaningful one (although may be uninteresting to the OP) is to ask whether there exists an explicit way to tell whether an element of $\mathbb{C}_p$ (or of $\overline{\mathbb{Q}_p}$ or of any field $K\supseteq\mathbb{Q}_p$) which is trascendental over $\mathbb{Q}$ is already in $\mathbb{Q}_p$: like testing whether a trascendental complex number is real but in the $p$-adic world. If $K/\mathbb{Q}_p$ is not Galois, it seems interesting.

comment What non-categorical applications are there of homotopical algebra?
Wow! Great, great answer.

comment Example of a non-smooth irreducible component of the generic fibre of a Hida family?
@KevinVentullo: Yes, thanks! I was able to download it and it contains pretty much what I was looking for.

@Kevin(B.): sorry for my comment which is not related to your question, but do you have an explicit reference where computations/examples are made/provided for a CM family meeting a non-CM one? Thanks.
