And then based Grothendieck said, "fuck it, every universe is strictly contained by some larger universe. Now shut up and do some real math." I suggest you take the last sentence to heart.

Just so old as your mother was when I banged her first.

It's not just having groups of sets that leads to inconsistencies, it's calling those groups "sets." Changing the name is all that needed to happen

This is probably one of the worst threads on sci in a while.

>mathfags invent the idea of 0
>mathfags realize that their idea of 0 allowed for paradoxes
>mathfags come up with limits and indeterminate forms then formalize a consistent set of axioms for them
>mathfags then use "calculus" to answer questions they couldn't without division by 0, even though they know that this leads to inconsistencies.

Past PDE and complex variables (pencil and paper math), I have to agree with OP. Remember, all of practical math fits into Mary Boas' Math Methods book.

My friend quit his PhD because he realized his thesis subject was ultimately worthless.

People don't study math because they think it is going to be useful or recognized or valuable; it's basically maymay-tier knowledge now that mathematicians do research because it interests them. I only study math because it makes me stupidly happy.

>>7233438

And like much maymay-tier knowledge, that's crap.

Speak for yourself.

"One of Newton's greatest critics was George Berkeley (1685-1753), the dean of the Church of England in Ireland.[7, p.333] He was a vehement and highly competent critic of many aspect's of Newtonian science and sought to show that Newton's universe was constructed on quicksand. [4, p.210] Berkeley's main attack can be found in a publication entitled The Analyst. He hit the method of fluxions in its weak spot - the infinitesimals, which he called "the ghosts of departed quantities."[7, p.333] He said "He who is willing to accept the mysteries of the calculus, which nevertheless lead to true results, need not hesitate to accept the mysteries of religion" [7, p.333 as quoted in The Analyst]."

Of course they aren't division by 0 you dolt, that's the point of a gross oversimplification. Newton was actually criticized over the fact that calculus was effectively based on what looked like division by 0.
