@scholadaily: What is category theory? Category theory is a high-level branch of mathematics that formalizes mathematical structure and relationships, focusing on objects, morphisms (arrows), and composition. Often nicknamed "generalized abstract nonsense", it serves as a unifying language for all of mathematics and theoretical computer science. Core Components of a Category Objects: The basic entities or "nodes" in a system (such as sets, groups, or topological spaces).Morphisms: The directed arrows or structure-preserving relationships between objects (such as functions or homomorphisms). Composition: A rule to link two sequential arrows (A->B) and (B->C) into a single combined arrow (A->C), which must be associative. Identity: A "do-nothing" arrow assigned to each object that maps the object back to itself. Key Higher-Level Concepts Functors: Mappings between different categories that preserve the categorical structure (transforming objects and arrows of one category into another). Natural Transformations: Ways of mapping one functor to another, providing a formal sense of how different constructions relate. Adjunctions: A pervasive relationship between pairs of functors that captures a vast number of universal properties and constructions across mathematics. Applications Mathematics: Unifies disparate fields like geometry, algebra, and topology by revealing shared structural patterns. Computer Science: Provides foundational semantics for functional programming languages, type theory, and database schemas. Follow for more!! #scholadaily #math #education #physics #quant @ScholaMex

what do you call a person that reads category theory? a coauthor

ibbbbs :

It’s funny that this meme is about category theory. In real life it’s hard to find anyone who is interested in category theory, even at a very basic level. But people who watch a couple of videos about quantum physics and then start talking about the universe are everywhere. Category theory is not nearly as difficult as people make it sound. Its basic concepts are actually quite simple. In many ways, it’s like set theory, a foundational language for mathematics. I think it could be introduced to undergraduate math students after their first year. I’ve looked into category theory and honestly, I don’t see why people say it’s so difficult. I find quantum physics, classical mechanics, and even the mathematical background behind machine learning much more challenging.

lie theory is more interesting

that was my friend Joey Stern,at the honors college of CUNY before getting his postdoc at mit. we haven't talked in years. but he'd put category theory and diagram chasing into calculus. it was nuts. 🙄
