What about people who don't want all of their real life relationships to be able to follow them online? For example, suppose someone has a restraining order against a stalker, so they don't want to be findable online. Does that me

My father was a mathematician. In graduate school, he didn't do quite as well as expected on his oral exams. As a result, afterward one of his committee members talked to him about possible career alternatives to mathematics. This prof

I suspect too many people would interpret "research" as (their view of) academic research: no definite goal, no time limit, no constraints. A spike is supposed to be a time-limited investigation of something specific. After that t
