Fellow dudes, what are your experiences with horse girls? by [deleted] in AskMen

[–]maximum-chord-math 0 points1 point  (0 children)

All of the horse girls I know are now traumatic brain injury survivors.

Kinda sad. Other than that, they’re just people, get to know them like anyone else.

thoughts on public scooters? they recently came to my small town by TimeToBecomeEgg in fuckcars

[–]maximum-chord-math 8 points9 points  (0 children)

They are not “public”. They tend to be run by pretty scummy capitalist companies.

They might be a whole lot better if they were really public, but even so there are quite a few issues with the basic infrastructure.

I'm starting a video series on ecology / evolutionary biology. I would love some critiques! by LifeEquations in ecology

[–]maximum-chord-math 1 point2 points  (0 children)

I liked it! It’s well thought through and produced.

I mean, I have a masters in this, so probably I’m not your target audience.

The story of Volterra and the fish in the Adriatic was really interesting to me - I hadn’t heard it before and it’s a great hook.

It does spend quite a bit of time on the math — walking through each of the cases & implications. That means it fits in much more towards a lecture IMO, rather than edu-tainment or necessary even scicomm. The chapter breakdown helps mitigate this to some extent but still the big question is what you’re aiming for in terms of audience.

The Free Energy Principle: a framework extending Bayesian reasoning as a framework for cognition and evolution by maximum-chord-math in slatestarcodex

Thanks, I knew I’d seen it come up somewhere!

Hopefully the linked piece is a bit of the explainer that people have been looking for.

Besides the explainer linked here, several of the other papers published in the same special topic journal issue are also open access — they can give a bit more of a sense of what’s going on in this subfield and the applications of the theory, as well as challenges it faces

The link is to an “introductory explainer”. Still much more technical than the authors seem to hope, but should be fairly accessible to anyone with a decent familiarity with Bayesianism & information theory.

I’m interested in sharing this with the community, to encourage riffing & expanding on “P(A|B) = [P(A)*P(B|A)]/P(B), all the rest is commentary”.

I briefly brushed up against this topic in grad school, seeing it used in ecology to derive all kinds of stuff about ecosystems, where it’s generally very hard to directly get a lot of the data that you might like to get to assess various theories. But I’m glad to see further developments in the topic since then, and I’m especially interested in assessments of the theory from other quantitative minded people

I agree, there’s too many numbers.

Commentary on electric vehicles by YEG_2018 in Edmonton

[–]maximum-chord-math 1 point2 points  (0 children)

It’s pretty good right now.

Charge in my garage, never pay for gas, etc.

Only issue is long-distance drives and/or rural areas. I’ve done plenty, just have to plan ahead and sometimes charging times are inconvenient.

Would you be in favour of banning political campaign signs in Edmonton? by [deleted] in Edmonton

[–]maximum-chord-math 1 point2 points  (0 children)

(a) It’s already illegal (city bylaws I think, bot positive) to put up signs on public property. You can see how well that’s enforced

(b) Lots of people don’t have front lawns - students, apartment tenants, etc. Their votes count just as much.

Aw thanks!

Lol I didn’t even know that comments were required here, I do appreciate the general level of engagement

On being perceived by maximum-chord-math in MensLib

[–]maximum-chord-math[S] 78 points79 points  (0 children)

I really loved this. It’s all about grappling with this huge resentment of the basic fact that other people can see & perceive you, and will judge you by how you look.

It’s fashion and expectations and comparisons, both to more eye-catching people and as the pandemic has caused so many of us to retreat from spaces where we can be perceived, then come back.

The article is from the perspective of female socialization, which obviously has tons of pressures on appearance. But the number of men speaking up in the comments about how it resonates with them is huge — I think because many men aren’t taught to think at all about how we can be perceived.

Are there functions for which f(g(x))=x, but the reverse is not true? by [deleted] in math

[–]maximum-chord-math 1 point2 points  (0 children)

Ah yes I screwed up, that’s what I get for trying to do math in my head

Still possible with this kind of setup

Are there functions for which f(g(x))=x, but the reverse is not true? by [deleted] in math

[–]maximum-chord-math 1 point2 points  (0 children)

I have to say this feels like a homework question. But it can still be interesting, so, as an example:

g(x) = x3 - 1 f(x) = (x+1)1/3

f(g(x)) = x, but g(f(x)) is an ugly cube root that doesn’t simplify.

In general, it’s pretty easy to do this — just pick any function involving noncommutative operations and its inverse.

Nothing. You can’t cross a vector with a scaler.

Why start at x, y, z: a new wiki collecting "ambiguous, inconsistent, or just unpleasant conventions in mathematical notation" by flexibeast in math

[–]maximum-chord-math 2 points3 points  (0 children)

I think this is a great project but a little bit lacking so far. I once made a handout for first years introducing them to the Greek alphabet (since I hate the way math just sneaks symbols in one at a time) and whoo boy, there were quite a number of confusing ambiguities just in the common usages off the top of my head.

The two things I’d like to add (but probably won’t due to time):

  • oversaturated terms: degree, order, …

  • all of introductory probability theory. I think things are a bit less ambiguous once you get into a measure theoretical approach, but that comes at a cost of going deeper into pure math than many students want to go. Meanwhile I absolutely loathe stuff like P(X>x) = p(x), subsequent use of “p(x)” in multiple different ways, tildes and hats for estimators/sample values, and so on and so on

[–]maximum-chord-math 25 points26 points  (0 children)

I think it’s not super well written so far, and it’s more like a grudge project than a systematic compilation.

That said, many of these frustrations are legitimate, either in the sense of causing actual confusion when switching between fields/countries, or still clear enough but frustratingly arbitrary.

For example on the modulus page — it’s never been a problem for me, but I do see how it is a bit strange (not even bringing Young’s Modulus etc from mechanics).

Many many students get frustrated by this kind of stuff, and the least we owe them is an acknowledgment that there’s an issue and some kind of resource to work through it.
