I think it’s disingenuous to say those two murders turned public opinion when those two murders were a direct result of public opinion already turning. Everyone has grown up immersed in propaganda, it’s not helpful to shame people for shedding that too late.


















Try reading about the computer science topics that basically are pure mathematics. Read about automata (very simple models for computers) or about computability theory (which asks what problems are literally impossible for computers to solve, even with unlimited time and memory). There won’t be too many numbers or equations involved in getting your feet wet with these topics.
Let’s say you have a keyboard with only three letters: ‘X’, ‘Y’, and ‘Z’. That’s our “alphabet”, it has just three letters in it. Let’s plug this keyboard into a monitor that’s really broken, actually all that works is one pixel that has four possible color options. We can have our machine start at white when you press the power button to turn it on, and when you hit black it shuts down. We could still teach a kid some basic programming ideas with this limited setup - If we’re on white and press ‘X’, change the color to green. If we’re on white and press ‘Y’, change the color to blue. Maybe pressing ‘Z’ from blue will get you back to white, but pressing ‘X’ will take you to black. Maybe some other rules too. This simple machine is called a finite automaton.
What “words” (strings) can we type in after powering on to shut the computer down? From what I’ve laid out so far, we power on to white, can press Y to go to blue and then X to go to black. “YX” is a string that works here. We could also do “YZYX” or “YZYZYX”. The set of all strings that will power down our machine from boot are called its “language”.
An automata theory question might ask if we can write a program on this machine that has both words “XYZ” and “XYX” in its language, but not “ZZZ”.
If you’ve tried read this and have trouble following, that’s because math is hard! (and totally not because I can’t explain for shit.) If you’ve tried to read this and don’t feel like it’s hopeless to learn, that’s probably because you’re not even seeing this as math at all. (Theoretical questions like this are absolutely math problems.) If you’ve read this and have already figured out an answer to the question I posed in the last paragraph, then your problem with learning math definitely isn’t that you’re hopelessly bad, so we’ll have to troubleshoot elsewhere.
If you learn these subjects you’ll eventually need the groundwork from more basic mathematics, but you’ll have some motivation for why they might be needed.
I started writing this intending to tag on a rant about how math being used as a gatekeeper in schooling poisons everyone’s idea of what math actually is and makes a ton of people wrongly feel hopeless, but this comment is long enough as it is.
