📺 “United Shades of America” Latino, USA | CNN

Watched "United Shades of America" Latino, USA from CNN
With W. Kamau Bell. The population of East Los Angeles is over 90 percent Latino; they are predicted to be the majority population of Americans by 2044; W. Kamau Bell speaks to many Latinos who are fighting prejudice and spreading the message of tolerance.
It helps to watch an episode reflecting some culture in my own back yard. I’ve now got a better barometer by which to judge some of the rest of the series.

Kamau gets it pretty solid, though there’s a lot more poverty and struggle while his version here makes things seem much more upbeat. Like Kamau in this episode, I’m almost tempted to say “Soy Chicano tambien.”

Acquired Category Theory for the Sciences by David I. Spivak

Acquired Category Theory for the Sciences by David I. Spivak (The MIT Press, 1st Edition)

An introduction to category theory as a rigorous, flexible, and coherent modeling language that can be used across the sciences.

Category theory was invented in the 1940s to unify and synthesize different areas in mathematics, and it has proven remarkably successful in enabling powerful communication between disparate fields and subfields within mathematics. This book shows that category theory can be useful outside of mathematics as a rigorous, flexible, and coherent modeling language throughout the sciences. Information is inherently dynamic; the same ideas can be organized and reorganized in countless ways, and the ability to translate between such organizational structures is becoming increasingly important in the sciences. Category theory offers a unifying framework for information modeling that can facilitate the translation of knowledge between disciplines.

Written in an engaging and straightforward style, and assuming little background in mathematics, the book is rigorous but accessible to non-mathematicians. Using databases as an entry to category theory, it begins with sets and functions, then introduces the reader to notions that are fundamental in mathematics: monoids, groups, orders, and graphs―categories in disguise. After explaining the “big three” concepts of category theory―categories, functors, and natural transformations―the book covers other topics, including limits, colimits, functor categories, sheaves, monads, and operads. The book explains category theory by examples and exercises rather than focusing on theorems and proofs. It includes more than 300 exercises, with solutions.

Category Theory for the Sciences is intended to create a bridge between the vast array of mathematical concepts used by mathematicians and the models and frameworks of such scientific disciplines as computation, neuroscience, and physics.

📺 “United Shades of America” The New KKK | CNN

Watched "United Shades of America" The New KKK from CNN
With W. Kamau Bell. WKB visits the "new" and "improved" KKK that is more concerned about its branding but still has the same hate.
I’m curious if this would look quite the same if made again now, just a bit over two years later?

I’m given some hope by Kamau’s experience in the small town with what seemed like the majority of the people there.
