Assumptions of Physics Reading Group

See Sabine Hossenfelder on The Laws of Physics and https://assumptionsofphysics.org/book/.

15:48 On covariant physics in flat space, see Newton–Cartan theory and Maggie Lieu on turning off gravity.

34:14 Wikipedia "A product integral is any product-based counterpart of the usual sum-based integral of calculus. The product integral was developed by the mathematician Vito Volterra in 1887 to solve systems of linear differential equations. ... For the case of f:[a,b]→ \mathbb{R}, the product integral reduces exactly to the case of Lebesgue integration, that is, to classical calculus. Thus, the interesting cases arise for functions f:[a,b]→A where A is either some commutative algebra, such as a finite-dimensional matrix field, or if A is a non-commutative algebra."

See also Expansion of the infinite product [Math Processing Error] etc. into a simple series by Leonhard Euler and Jordan Bell, this Mathologer video about Euler's product formula then this one about continued fractions. And then, if you're still bored, see Burkard Polster trying to start a revolution and me Trying to Make a Sci-Fi Movie.

A derivative is linearisation, and differential calculus is essentially linear algebra, ...  See  Freya Holmér - Why Can't You Multiply Vectors?  and  Freya Holmér on Continuity of Splines .

Hitachi HD44780U LCD Display Fonts

I finally got the bit-mapped fonts from the Hitachi "1602" display :  Here's some JavaScript: const HD44780U01ASCII=[ [],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[], [],[],[],[],[],[],[],[],[],[],[],[],[],[],[],[], [0, 0, 0, 0, 0, 0, 0, 0, 0, 0, ], [4, 4, 4, 4, 0, 0, 4, 0, 0, 0, ], [10, 10, 10, 0, 0, 0, 0, 0, 0, 0, ], [10, 10, 31, 10, 31, 10, 10, 0, 0, 0, ], [4, 15, 20, 14, 5, 30, 4, 0, 0, 0, ], [24, 25, 2, 4, 8, 19, 3, 0, 0, 0, ], [12, 18, 20, 8, 21, 18, 13, 0, 0, 0, ], [12, 4, 8, 0, 0, 0, 0, 0, 0, 0, ], [2, 4, 8, 8, 8, 4, 2, 0, 0, 0, ], [8, 4, 2, 2, 2, 4, 8, 0, 0, 0, ], [0, 4, 21, 14, 21, 4, 0, 0, 0, 0, ], [0, 4, 4, 31, 4, 4, 0, 0, 0, 0, ], [0, 0, 0, 0, 12, 4, 8, 0, 0, 0, ], [0, 0, 0, 31, 0, 0, 0, 0, 0, 0, ], [0, 0, 0, 0, 0, 12, 12, 0, 0, 0, ], [0, 1, 2, 4, 8, 16, 0, 0, 0, 0, ], [14, 17, 19, 21, 25, 17, 14, 0, 0, 0, ], [4, 12, 4, 4, 4, 4, 14, 0, 0, 0, ], [14, 17, 1, 2, 4, 8, 31, 0, 0, 0, ], [31, 2, 4, 2, 1, 17, 14, 0, 0, 0, ], [2, 6, 10, 18, 31, 2, 2, 0, 0,...

Using Pipewire to Make A Music Synthesizer

Illustration from Project Gutenberg's The Tenniel Illustrations for Carroll's Alice in Wonderland by Sir John Tenniel. Thinking about the linux desktop audio problem: I'm not the only one who finds this weird: https://t.co/b2BZMiak07 — eternal Doorman (@IanANGrant66) May 17, 2025  I noticed that if you change the volume using the Gnome volume keys it changes it in jumps. Usually you don't notice, but if you play a pure sine tone then you can easily hear the distortion. If you want to play with pipewire from C on Ubuntu 24.04 then it's really easy. The pipewire tutorials and examples can be compiled and run if you just first install the pipewire-0.3-dev package with sudo apt install libpipewire-0.3-dev But the API is sooo far away from pluggable, typed streams that I find it quite depressing. Is it because nobody understands the necessary type system . See  Programming Channel Processes and Alice's Adventures In The Wonderland Wide Web . [Update: y...
