[Pu] was recalled to the mainland after the communists ousted Chiang Kaishek in ’49. Pu was henceforth confined to research in fuzzy topology in the
service of the people.

An alternative approach is to use [Grothendieck] universes, but this requires assuming additional set-theoretic axioms. The reader is invited to ignore such questions.

—James Milne

…standard methods are stymied by the possibility of an exceptional zero, violating the Riemann hypothesis, lying very close to 1. Such a zero does not exist—but this cannot be proved. The usual proof of Linnik’s theorem…establishes an “exceptional zero repulsion” principle, akin to proving that at most one of Santa Claus and the Tooth Fairy exist.

The geometry of Banach spaces lies in darkness and has attracted the attention of many talented research mathematicians.

The problem is most easily grasped when stated in the language of cricket.

The mathematics that comes from the ‘baroque’ inbreeding of the work of people with bad taste is often ugly and doomed to quick oblivion. The instinctive good taste of the geniuses who led the way is needed to guide the rest of us, and when we don't let it, we get generalization for the sake of generalization. We get what I have heard Zygmund call centipede mathematics (remove 99 legs and see what it can do); we get the elaborate elaborations of Baire category theory in fuzzy topological semigroup.
