RailsConf 2022 - Reflecting on Active Record Associations by Daniel Colson
Active Record associations seem magical—add a has_many here, a belongs_to there, and suddenly your models are loaded with behavior. Could it be magic, or is it plain old Ruby with some thoughtful design and a bit of metaprogramming? In this talk we'll study Active Record associations by wr

The most misunderstood equation in math (associative property)
Associativity is one of the first properties taught to students. Let's explore this property together. For the curious among you, the mathematical theorem at the heart of this video is Cayley’s theorem for semigroups. 00:00 The equation 02:20 Exploration 13:36 What is associativity? Part

Commutative algebra 28 Geometry of associated primes
This lecture is part of an online course on commutative algebra, following the book "Commutative algebra with a view toward algebraic geometry" by David Eisenbud. We give a geometric interpretation of Ass(M), the set of associated primes of M, by showing that its closure is the support Su

L. Boyle: Non-commutative geometry, non-associative geometry, and the std. model of particle physics
Connes' notion of non-commutative geometry (NCG) generalizes Riemannian geometry and yields a striking reinterepretation of the standard model of particle physics, coupled to Einstein gravity. We suggest a simple reformulation with two key mathematical advantages: (i) it unifies many of t

A gentle description of a vertex algebra.
Working from the notions of associative algebras, Lie algebras, and Poisson algebras we build the idea of a vertex algebra. We end with the proper definition as well as an "intuition" for how to think of the parts. Please Subscribe: https://www.youtube.com/michaelpennmath?sub_confirmation
