Sometimes I read a comment on HN that is so advanced that it's just as readable to me as Greek. Love reading it just to see someone work though!

I used to feel this way about statistics.
The language and terms are hard to understand and many of the formulas are taught as "just memorize this" instead of building up from first principles.
But then I started using statistics to analyze something I cared a lot about (paintball) and I quickly realized it's like learning anything new:
- there is jargon
- and core concepts
- when you learn the above, it suddenly makes a lot more sense.
This is my exact experience right now trying to wade through the research on psychometrics and skill/knowledge assessment design. It’s mostly just applied statistics but like all such fields, over decades of specialization it acquired its own jargon for abstractions that are quickly recognizable to anyone with a sufficiently developed nose for modern mathematics. But you still have to wade through all the definitions to make those connections before you actually understand everything.
I gotta know what you use stats for regarding paintball. I haven't played in years but I loved playing back in the tipman 98 custom era (not sure if that's still a popular marker).
So I wrote a whole bunch about college paintball statistics here: https://www.pbnation.com/showthread.php?t=3949120
Then I wrote some more about pro paintball stats in the below three Reddit posts:

2. https://www.reddit.com/r/paintball/comments/1jy5xqp/paintbal...
3. https://www.reddit.com/r/paintball/comments/1k6bzi7/paintbal...
Some highlights:
- I started with just pen, paper and a stopwatch (as a college coach)
- I assumed paintball would be more like football where it's hard to track individual effects
- Turns out it's a surprisingly simple and stable "state machine". e.g. the odds of winning with +1 body (e.g. 5v4, 4v3 etc) is, in college, about ~75%
- Paintball is one of those sports where "the weakest player determines the outcome". Why? b/c if 1 player gets out early, you are fighting out of a hole.
It also made me appreciate that as good a book as Moneyball is, reading it after you try to create analytics for your own sport makes it 3x as enjoyable/insightful.
One downside though:
I would watch games and I got so good at internalizing the stats per state of the game that it was like watching the world series of poker where I could see both player odds of getting eliminated and probability of winning over time charts as I watched the games. Made it harder to be the "come on guys! we can win this" coach when we were down on points + bodies.
Wow, a blast from the past to be sure. Was not but any means avid, but did own a tipman. And was always dazzled when someone showed up with an angel.
That era is now! (Still)

This is a great suggestion, use complex hard stuff for doing fun stuff.
Not to diminish the comment, but most things are not as complex as they sound when phrased in everyday language or sound much more complex than they are when phrased in technical language.
Technical language is a tool that allows insiders to say less and refer to more, and to be specific, but it's just a tool. Most things can be described in accessible ways.
I think you'd be surprised at what you could understand and at just how few domains are truly complex enough that a layman couldn't understand with a little bit of patience and an accessible summary.
Saying things colloquially gives everyone an intuition about it.
You'd think intuition is great, but no, about half of the important things are counter intuitive.
That makes intuitive thinking about complex technical topics you don't know enough about worse than useless.
It took me a while to understand a lot of these math concepts.
Turns out people doing Engineering research are using a very small but powerful bag of tricks from a handful of few famous Mathematicians. The concepts are named after them!
I don’t think OP made much effort to make the comment accessible to non-experts, and so it should be taken as a gauge of the fundamental difficulty of the topic.
Thanks for posting this comment, it makes me proud of myself to be able to partially comprehend the comment :)
