  • Sorry to reply to this so late, I procrastinated because unfortunately my answer is that I don’t know of any communities, perhaps because I’m a scientist who loves maths rather than a mathematician.

    However, I will use this opportunity to share some fun stuff from people I like.

    https://youtu.be/H0Ek86IH-3Y by Oliver Lugg on Youtube is great. His channel is very eclectic though, and there isn’t much pure maths. I love his shitposting tone though, and he has a discord community that were pretty mathsy when I was in it.

    A blog-type site that I enjoy is Tai-Danae Bradley’s https://www.math3ma.com/about, largely because I’ve discovered many other cool researchers through her site.

    I also really enjoy Eugenia Cheng’s books, especially as someone who is interested in understanding how to write good scientific communication that is accessible without “dumbing things down”. I recently finished “The Joy of Abstraction”.

    Apologies that this isn’t what you actually were looking for. I share your distaste at Reddit: I have used Reddit occasionally for those niche communities that aren’t available elsewhere (yet!), but the atmosphere is increasingly toxic. I fear that smaller communities that flee are congealing in harder to discover places, like Discord.




  • I have a lot of ebooks that I download for university research, hobby learning and friends who ask for help sourcing books. I put everything in my calibre library, which is great for metadata management (tip: I have it set so new books that I’ve just imported get a tag of “new”, which I remove when I have processed their metadata. This allows me to chip away at ensuring the metadata is correct and good, even if I don’t do it at time of import).

    Anyway, at one point I found myself at risk of becoming overwhelmed by books, because if I’m wanting to learn some category theory, for example, I’d have multiple books that seem to be relevant. Some of them were recommended by programmers, some of them assume a higher level of maths background knowledge, some of them are more fun to read — once upon a time I might’ve known which was which, but if there’s a significant gap between me downloading stuff and using it (which is often the case, I’m quite opportunistic with book recommendations), I may forget. Making a note of why I downloaded a particular book is something I’ve been trying to do more, so I can identify the useful things at the right time — the calibre notes field can work for that, but I’m still figuring out how to manage this in a wider sense because I do a lot of reading and it’s easy to forget why I’m reading a particular thing. I think I have a calibre plugin to show which things I’ve read also.

    Another related thing is that I will take a cursory look over a book when I download it, and I may delete it and not put it into my calibre library. This feels significant because downloading a book doesn’t make it one of my books, ‘taking it home’ and putting it away on my ‘bookshelf’ makes it mine. In short, I try to be mindful in my curation activities, recognising that doing it in big clumps with my whole collection doesn’t really work and that pruning little and often helps more.





  • Scientists’ words will always be twisted, regardless of what words they use. I agree that some words seem to sow confusion even within research fields, but I worry that attempting to change things may lead to an xkcd standards problem

    A book that has really stuck with me is “Merchants of a Doubt”, which looks at how often the muddying the waters comes from a handful of scientists, who are presumably getting paid a bunch to do so, but not in a way that’s easy to debunk. The problem is that science is muddy by nature, so scientists learn how to wade through mud (ideally) and work around and through it. I’m of the belief that the way forward will require for science in general to become more accessible to people in general, because I think the epistemically privileged nature of science is deepening distrust i.e. we are taught to trust science™ and only scientists are allowed to challenge other scientists. This makes sense, but I think it fosters a sense of distrust in people who I honestly can’t blame for feeling like the system doesn’t care about them.

    I’m feeling like maybe blind trust in institutions might just be an untenably bad situation, because I’m a scientist and I don’t know whether scientific education in the model of "scientific communication happens when the Scientists™ come down from their ivory towers and gift the common folk with knowledge, who are not allowed to question or add to this knowledge, unless they become a member of Science™ (or they are a person to whom science is done to





  • I shouldn’t have left my previous statement without any elaboration — that was a pretty inflammatory comment to make and I apologise.

    When I say “gravity is a social construct”, part of what I’m getting at is that the natural world is distinct from scientific knowledge we create when attempting to model the natural world, and that our scientific knowledge is, by necessity, socially mediated.

    I like gravity as an example of this because of how fundamental it is: even animals have some level of intuitive understanding of gravity — they don’t need to understand what parabolic motion is to be able to demonstrate it when they jump over things.

    But also, our understanding of gravity has vastly changed over the years. In the 1800s, astronomers had measured Mercury’s orbit so precisely that they found it to be inconsistent with what Newton’s Law of Universal Gravity would predict, so they figured there had to be another planet closer to the Sun. Turns out there wasn’t though, and it was only after Einstein’s theory of relativity that Mercury’s weird orbit could be explained.

    They had good reason to guess that another planet was responsible for Mercury’s orbit though, because the same guy who made that guess (a French astronomer, Urbain le Verrier) had actually predicted the existence of Neptune just a few years earlier; he had used Newtonian gravity to analyse the orbit of Uranus and found that it was slightly off from what observers had been measuring, and deduced that there must be another planet that nobody had seen yet that was causing these perturbations.

    These two examples show two different ways that we can respond to experimental observations not matching with our theoretical understanding: sometimes it’s productive to assume our current theory is correct and that our observations are wrong or insufficient in some way, and sometimes we fix the disparity between what we see and what we know by amending our theories, like we did when we learned the limits of Newtonian gravity. Choosing which hypothesis to investigate is how science (and scientific knowledge) is socially constructed.

    Disclaimer: I’m a biochemist, not an astrophysicist, so talking about gravity isn’t my primary domain. Many of these ideas are articulated far better in this video essay by Dr Fatima (and I suspect some of my phrasing is subconsciously borrowed from this video — this is bad citation practice on my part)



  • It’s a bit more complex.

    The bacteria causing this (Streptococcus pyogenes) causes hundreds of millions of illnesses each year, ranging from the mild “strep throat” to the extremely severe scarlet fever. Whilst there have been a few outbreaks of antibiotic resistant strains of this bacterium, that doesn’t appear to be what’s going on in this outbreak, so thankfully the underlying streptococcus infection should be treatable with standard antibiotics.

    Unfortunately, the condition that’s actually killing people (Streptococcal Toxic Shock Syndrome (STSS)) is caused by exotoxins released by the bacteria, and killing the bacteria only stops further exotoxins from being produced — antibiotics can’t do anything about the exotoxins that have already been secreted by the bacteria. If you’ve ever wondered why we can’t cook spoiled food to make it safe to eat, this is a large part of why — exotoxins are often better at sticking around than the bacteria that produce them. It doesn’t help that exotoxins are often super potent toxins (Botulism is a particularly potent and well known example).

    It’s not clear what causes some cases of Streptococcus pyogenes to escalate and non-eventful cases of strep are common enough that treating every case with antibiotics is implausible. It’s tricky because if symptoms are severe enough to warrant a diagnosis of STSS, then things will have already progressed enough that the exotoxins present s risk to health even if antibiotics are administered. This outbreak of many cases of the severe STSS is concerning because it might indicate that the strep bacteria has evolved to be more deadly, but we really don’t know why there’s such a cluster of severe illness in one place.


  • I wonder what would facilitate people to make their own solutions in this way. Like, I have made a few apps or automation things myself, but if I look at my “normie” friends who don’t have the level of tech familiarity that I do, they struggle with whatever out of the box solutions they can find. Poor IT education is a big part of this, and I’ve been wondering a lot about what would need to change for the average “normie” to be empowered to tinker



  • I’ve never used a cup before, but I know for certain, you can’t really do that with tampons, because it would be way too dry and eugh, even imagining that is making me shudder. Most women who use tampons know how unpleasant it feels to pull out a dry tampon; I have to be careful near the end of my period not to use a tampon with too high an absorbency if I want to avoid this. I may switch to pads near the end.

    Periods can come without warning though. Some people have a super low flow early on, so they might get more warning (if they go pee and there’s a lil blood when they wipe), but also sometimes it’s heaviest at the start, which is why many women have embarrassing stories of their period taking them off guard and bleeding through their clothing onto a chair or something. Someone might wear pads if they’re expecting their period - you can get lighter absorbency pads that might suit this better. Older women might wear pads like this at other times - my mum occasionally pees a little if she sneezes too hard, so she wears lightweight pads at other times of the month.

    It’s easier if you can predict when your period will be. I’ve never had a regular cycle, and I thought the whole “my period is 2 days late and I’m anxious that this might mean I’m pregnant” thing only happened in movies until a friend anxiously messaged me about it. Turns out some people do have that level of regularity - I might actually ask my super regular friend what she does when expecting her period, come to think of it. But yeah, for many people, it can’t even be predicted to the day, or even the week.

    Edit: reading other responses to your question made me think of amother point: even if you have irregular cycles, it can be possible to predict by various bodily signs. Something that I don’t hear talked about much is how vaginal discharge changes over the menstrual cycle. When I’m ovulating, there tends to be more discharge, and it’s slippery and clear, almost like egg whites in texture. At other times in my cycle, it might be more white coloured, or more creamy, or more sticky. I find it gross and fascinating in equal measure — sometimes I’ll just stick a finger up there to check if I’m unsure where I am in my cycle


  • The other person who you replied to makes good points - it’s always going to be context dependent and it drives me mad when I’m out and about and have so many signals projecting “leave me alone” (such as wearing headphones, being on the phone, studying etc.) and a guy hits on me.

    However, if someone is generally approachable, I’ve found that the best compliments are on something the person has consciously chosen about their appearance. So stuff like graphic t-shirts (especially band t shirts), hair styles (I love people with dyed hair because this presents to me an easy option for compliments).
