The book in the course [1], specially ch. 4, I think, provides some analytical category-theoretical tools to model feasibility/performance in that kind of situation. In [2] the same technique (enriched profunctors) applies for critical

It was expensive in phone line charges intercity. It was slow, as in hollywood hacker movies where characters printed one at a time making funny noises. And it was a thrill. It is now hard to apraise how isolating is being limited to intera

I'm starting to dive into the Path Integral formulation and this is taking me to turn things upside-down from what I thought of the order of what relies on what. I've started to get Baez's view [1] and given that, the questio

Absolutely, I own a Sony DPTS and the size is essential to read non reflowable technical papers (i. e., most of them). Hope that gets built somewhen.

An ad fontes breadcrumb elucidation I think that passes through Gödel 1934, in §9 "General recursive functions". "...this leads to the question what one would mean by 'every recursive function'. One may attempt

For me when I was learning this the first problem was to grab what Mac Lane intended to say with "monoids" exactly (in monads are monoids such that blah) since the default notion from algebra didn't match (unital semigroup)

Interesting and saved. Some time ago I wanted to say that if I can represent a graph as an adjacency matrix, then I would have liked to say that an hypergraph is given by an adjacency tensor . I searched for that but couldn't find any

Shiller PER is at 38.5 [1], signaling overheating. Is it now a wise moment to do an all-in of your savings in an S&P index replica? It is dubious to me. I buy bogleheading in general, but some market timing thinking seems unavoidable to

A digression is that what multiplying A and A^T really means, in the sense that A represents a map of spaces, but A^T represents a map in the opposite direction of the dual spaces. In finite dimension or in topological vector spaces, a spac
