Oct 6 comment Why do roots of polynomials tend to have absolute value close to 1? @Andrej I noticed the slight tendency of the roots to cluster near 1 and to disperse more near -1, and I'm curious if anyone can provide a statistical explanation to explain this effect. It does seem that there is a strong tendency to be nearly uniform, and this is sort of a second-order thing.

Oct 1 comment What are $( \infty , n)$-categories useful for? Seems to me that $(\infty, 1)$-categories are supposed to be considered as an enrichment of the concept of just "category"; i.e. they are not higher categories so much as they are deeper categories. Then $(\infty, n)$-categories are deeper, higher categories. Do you think that ordinary higher categories (i.e. 2-categories, 3-categories, etc.) are useful? If so, then their infinity version must be even more useful.

Neither $-1$ nor 0 works, as they are contained in every field. Sep 29 comment What is the most useful non-existing object of your field? @downvoter if you don't like the joke, it's enough just not to laugh. Sep 29 comment What is the most useful non-existing object of your field? @Toby Yes, that's right.
