An unexpectedly pleasant result of teaching myself some abstract algebra and number theory is that I get to properly indulge my inner child, who is deeply resentful that anyone ever demanded that she believe something based on appeal to authority.

Despite being moved into "two years ahead of most kids" math starting around age 13, until I hit some theoretical computer science stuff in college, it was mostly practical technique and very little proof and hard for me to fake interest in.

(TBH, most of the practically-orineted engineering and computer programming-related math technique that was actually worthwhile to me was limited to signal processing courses and a numerical analysis course.)

Also I'm kind of low-key annoyed that I learned of transcendental numbers when I was 13 but I didn't learn that the set of transcendental numbers has the same cardinality as the set of real numbers until two days ago

so I was reading wikipedia and found

https://en.wikipedia.org/wiki/Mammary_ridge#Milk_lines_in_humans

"[Recent study] focal fat pads on the front of human torsos are of mammary ridge origin. 8 pairs of fatty mounds were consistently found running along a curved line from the armpits to the groins [...] This finding explains why fat on the front of the body is less responsive to diet and exercise than fat elsewhere in most people -- [...] breast origin and therefore sensitive more to hormonal influence than caloric intake or burn."

A friend told me they had a dream that Bryan Johnson (the tech billionaire who seems to be transitioning into a woman in his quest to stay young forever) was raffling off packages of the food he eats to remain youthful and my friend won one of them.

When my friend got the food, it came in a minimalist plastic pouch like tuna would come in, except the label said it was human meat. My friend said they decided to try it in their dream.

Most of my old IRC crew, all of whom were obsessed with Linux, use Macs for work these days. I, who used to make fun of them for being so obsessed with Linux, have used nothing but that since 2019 or so. How the tables have turned

@recursive@hachyderm.io avatar

@rain I used Macs heavily from 2002 to 2012, got annoyed, started using Linux as much as I could, and now for the past 4 years or so been using Windows laptops/desktops.

It's mildly annoying to me when working on a product based on Linux to have to support my coworkers who expect to be able to develop or run parts of it natively on their Mac. (I'd be sympathetic if the product was expected to be portable across different Unix)

There are certainly worse ways of dealing with stress than "do a workout", but then it's frustrating when your body tells you it needs a rest.

Fortunately I can do a little running and walking without using the tired shoulder

Adjacent to this, I really dislike workplaces that normalize a lot of fucking around and timewasting during normal hours and then expect great productivity to happen somehow during your off-hours. Learn to have efficient meetings, maybe don't play foosball all day, IDK.

Reminiscing this morning about how theoretical computer science finally felt like fun to me rather late in my undergrad when they taught us how to prove a problem is NP-hard.

recursive, to random
@recursive@hachyderm.io avatar

Oh neat, I guess if I'm going to actually understand Shor's algorithm I'll have to understand the hidden subgroup problem, and this leads me to studying more abstract algebra. Tenatively this looks like fun (and relaxing compared to some stuff I have on my mind)

Nice to finally be getting to a phase of my life that I've had enough psychological growth to unblock kinds of executive function I didn't have long ago

Incidentally remembering how I worked on a 500k line Perl codebase that was well organized and probably 98% test coverage. It was easily 2 years into that job that I learned the difference between the .. operator in list context (range) and scalar context (flip-flop).

A "fun" fact about me is that I'm always approximately a short conversation from any discussion of flatness to pointing people to Foundations of Mechanical Accuracy https://archive.org/details/FoundationsOfMechanicalAccuracy/page/n3/mode/2up

This is a not-bad proof of the Whitworth three plate method
https://www.reddit.com/r/MechanicalEngineering/comments/c1je3j/comment/eredggu/
Although in the real world you never get a "perfect" surface, so I vaguely want to think about the correctness of applying this proof to say that in the real world case you are approaching perfect flatness with each stage of lapping, even though intuitively it's convincing

recursive,
@recursive@hachyderm.io avatar

Mostly I'm mad because I really want to see a formal proof of the optimality of this method, but I am very not in the mood for calculus or real analysis right now

you've heard of security by obscurity. mathematical notation is elitism by obscurity

recursive,
@recursive@hachyderm.io avatar

@eniko On the other hand, in my personal experience, I have a lot easier time reading unique symbols and understanding them as the same concept instead of dyslexically stumbling over two-word descriptions that look like practically any other two words that have the same shape. I think there are problems with papers which don't define obscure symbols at their introduction, but the accessibility of symbols vs words I think might go both ways depending on the reader.

recursive,
@recursive@hachyderm.io avatar

@eniko I'm someone who has had considerable difficulties with how math is taught, and I basically did the minimum of math I could in the course of getting a CS degree because I was pretty traumatized about it coming out of high school. I am finding I enjoy a lot of abstract math now, but that latent curiosity took me a while to separate from my bad experiences.

@eniko Out of curiosity, do you feel music notation is also elitism by obscurity?
