@goodgoyim9459 I guess Ramanujan didn't exist. Self-taught mathematicians today are everywhere and they publish in journals, too. It's hard to learn math by yourself, but people who succeed are not just ignored. A proof is a proof. It doesn't matter who wrote it.

@patekswiss9521 Mathematicians who work in education usually have good job security. In the best cases, they can get tenure, which is the ultimate job security. Mathematicians with "real jobs" also typically have excellent security and are not particularly worried about getting displaced. It's not like hairdressers who really need the licensing to hang onto their jobs.

@GrayFoxHound9 "Cathedra" is a technical term used by the Catholic Church. The same word is used in many languages, since it is actually Latin. The cathedra is a ceremonial throne that a bishop sits on. The closest analogy in a university would be the chair of a department, not the department itself.

@GrayFoxHound9 The word "cattedra" doesn't exist in English. I think you just mean "department." Anyway, I know very little about math and computer science in Russia. I do know that in the U.S., there are a lot of jobs available for people with a math background, including in teaching, and that they are not usually concerned that they will lose theirs. The fact that you had an adjunct who worked four separate jobs if anything indicates there are plenty of availabilities, but that they might just not pay well enough.

@GrayFoxHound9 Your cryptography teacher works at a cathedral?

The graph of z = e^ix for real x is a helix, not a spiral.
