First off, I have no interest in being a mathematician. Math was always and continues to be quite difficult for me.

So, as an outsider to advanced math, it blows my mind that there are people who's entire job title is mathematician. How does that work? What does a mathematician do?

Mathematician here (algebraic topology). Pure maths is pretty much an internship in academia. Applied math is anything between basically physics to actuary and finance. Since pure math is highly academic, though, there is no predefined job path following a degree, which is why the question is as interesting as it is hard to answer.

In academia, we do weird and wonderful things that only a few peers in the world probably will see and understand, due to the highly specialized fields of study. In industry, anecdotally, we do surprisingly little math and are mostly sought for analytical skills and proficiency in problem solving.

Sadly, most people that hire us outside of academia do not know much math themselves. I believe there are lots of real problems that could benefit from having a mathematician working on them, but there is just too little understanding of mathematics to identify the need.

An actual mathematician has arrived!

So, it seems from this whole thread that math for math's sake is not a money-making endeavor, but being the guy who runs the numbers for a company or institution is where the money comes from.

Is there a lot of stigma in pure math circles against people who move on to do applied mathematics?

Speaking from a pure maths' perspective here: Frankly, a little bit. I think at the university research level, the academically inclined professors might be a bit tired to be sidelined with the applied ones, especially when the latter are applauded for their industrial cooperation (read research investments) and appliances (read private ownership over publicly funded research). My study mates and I joked about applied math being dirty, but in reality it is more the absence of creativity and rigor that is the problem with applied math in my opinion.

To me, math is all about answering cool questions, sometimes posing even cooler questions in the process. Maybe an appropriate analogy would be whether an artist judges those that make commercials. Exploratory work can take a life of their own that is usually not possible when the format of the answer is predefined. That being said, I do not really judge, I only think that the different expressions are (usually) quite distinct in direction and content. I did not do math for money, though I rely on my mathematical skills for income.

Honestly I would love to hire a statistician to do the analysis on any clinical research I do. I just wanna collect the broset scores every shift and request and assign staff to best balance them then let somebody else count how many (hopefully less) people got punched by patients vs not doing that. No way even the research hospital would've paid for that though.
