FREE Math Book. "Introduction to Game Theory: a Discovery Approach" by Jennifer. Description: "Game theory is an excellent topic for a non-majors quantitative course as it develops math models to understand human behavior in social, political, and economic settings. The variety of applications can appeal to a broad range of students. Additionally, students can learn mathematics through playing games, something many choose to do in their spare time! This text also includes an exploration of the ideas of game theory through the rich context of popular culture. It contains sections on applications of the concepts to popular culture. It suggests films, television shows, and novels with themes from game theory. The questions in each of these sections are intended to serve as essay prompts for writing assignments. Many colleges offer courses in quantitative reasoning for all students. One model for a quantitative reasoning course is to provide students with a single cohesive topic. Ideally, such a topic can pique the curiosity of students with wide ranging academic interests and limited mathematical background. This text is intended for use in such a course. This text may also be appropriate for a high school enrichment course. Students can work through the text independently or as a class. The questions throughout the text help students discover the key ideas themselves. The text is free to download. The materials have been classroom-tested." -- Jennifer Firkins Nordstrom Link: nordstrommath.com/IntroGameT…

I've now advanced optimization theory. In this paper, we exploited a connection I realized between the primal-dual hybrid gradient method and averaged operator iterations to add a line search to PDHG over its step sizes and the relaxation parameter. link.springer.com/article/10…

We're in the realm with #AI where we were with food delivery and owner rentals a decade ago: gazillions of $$$ were subsidizing the costs to make the companies appear valuable so that the founders could profit from an #IPO. youtube.com/watch?v=zbKDmkJP…

We’re all going to buy $SPCX, whether we want to or not. It’ll be in our ETFs. There’s no need to sell $TSLA to buy it.

"Mathematical Methods for Computer Vision, Robotics, and Graphics" is a free Stanford resource with more than 200 pages of applied mathematics for modern technologies. The notes cover linear algebra, multivariable calculus, optimisation, differential equations, numerical methods, Fourier analysis, and geometry, always with a strong connection to real computational problems. What makes this material particularly interesting is that it bridges the gap between abstract mathematics and the technologies behind modern robotics, computer vision, computer graphics, and AI systems. It is a resource I strongly recommend to both readers who already have a solid mathematical foundation and those who want to deepen their understanding through a rigorous yet accessible treatment of the subject. graphics.stanford.edu/course…

I have found that the 2nd brain becomes a more effective search engine when I ask it to find research papers related to the subject matter in the vault.

Check out this absolute master piece by Jonathan Gratus titled '' A Pictorial Introduction to Differential Geometry, Leading to Maxwell Equations in 3 Pictures'' which is available on arXiv. To quote the author: ''When I was young, somewhere around 12, I was given a book on relativity, gravitation and cosmology. Being dyslexic I found reading the text torturous. However I really enjoyed the pictures.'' It's a short primer, full of nice figures, perfect for those who love visual examples.

Today I built a second brain. My feeling about it so far: meh.

I don't share geometry resources very often, but "Elementary Geometry from an Advanced Standpoint" by Edwin E. Moise is one that I think is worth bookmarking. It's a free book of more than 700 pages that covers Euclidean geometry, congruence, similarity, geometric transformations, analytic geometry, coordinates, constructions, areas, volumes, and the foundations of geometry, all with a rigorous yet readable university-level approach. Some of these topics may seem old-fashioned at first glance, but many ideas from classical geometry still appear today in computer graphics, computer vision, CAD, robotics, game engines, and geometric algorithms. ime.usp.br/~toscano/disc/202…

It's weird that socialism permits crimes that are destructive and also makes productivity a crime. It's like the point of the system is to destroy. When you see it that way, it achieves its goal every time.

Teaching in the age of LLMs: I failed 4 students, for the first time ever. I also gave more A 's than ever before. In previous years, students realized after the first or second HW that they weren't in Kansas anymore and needed to work hard. No more. Just solve it with LLMs. But then the midterm arrives, and they can answer 0 of 40 questions. Do they reform their ways? Nah, they just decide to "give up" on class, assuming they'll get a B, or a C, or whatever, because they submitted HW and got decent grades on those. And never before have they encountered a professor who will dare fail them. The flip side is that the most "agentic" students now have the world's best tutor at their disposal. They deeply understand the material and aced my (intentionally very difficult) exams. As if we live in "The Diamond Age". Inequality galore. From my vantage point, "the permanent underclass" appears to be about agency, not assets.

BREAKING: You might want to keep an eye on this one. Representative Maria Salazar bought stock in a small missile technology company. We haven't seen anyone in Congress trade it before.

This is straight out of Atlas Shrugged! "In the name of the general welfare, to protect the people's security, to achieve full equality and total stability, it is decreed that no new devices, inventions, products, or goods shall be produced, invented, manufactured or sold."

aerodynamics is not just air moving around wings. it is physics, geometry, computation, and design fighting each other. • lift • drag • pressure fields • shock waves • boundary layers • turbulence old-school aerodynamics was wind tunnels and equations. modern aerodynamics is computation. applied computational aerodynamics by russell m. cummings et al. shows how engineers use CFD to simulate airflow before cutting metal. • you model the shape • mesh the geometry • solve the flow equations • analyze the pressure field • iterate the design this is how aircraft, drones, rockets, turbines, and race cars are shaped now. not by guessing. by turning airflow into data.

This person actually believes that stocks move based on prices alone. His entire post doesn’t consider production, sales, macroecon, or even P/E! $TSLA selling at 700 would be 700X P/E, incorporating all expected future profits from all business lines. Not at all likely.
