    Oh right. Yeah I haven’t had the Facebook app installed on my phone in like a decade.

    But yeah, clicking on an image on the Facebook website doesn’t actually add it to your browser history, because Facebook tries to act like an SPA, a decision they made seemingly specifically to frustrate the user. Because in addition to not adding clicked images to your browser history, they also will refresh the page if you tab away and come back after a minute or two.

    Eh, not really. It’s more that at this level the difference in performance between men and women closes significantly, with some ultra swim records being held by women. For the English Channel specifically, the current record for speed of crossing is held by a man. So it’s not particularly amazing that it was a woman (though it is amazing that it was a physically disabled woman!), but neither would it have been amazing had it been a man.

    I’m not actually sure what you mean, but if I’m understanding it correctly, uhh, what? No they don’t. If you click an external link on Facebook they send you to it with a redirect, so they know you went to that site, but they don’t know of any further links you might click.

    But anyway, that’s not relevant to this here, because it was a photo shared on Facebook, not an external link.

    I fucking hate the way Facebook changed how the site works so that clicking on an image no longer puts it in your browser history. Earlier today I saw a post where the swimmer whose track was shown in this specific image responded to the comments. It was actually quite an amusing interaction and I wish I could go back and share it here.

    But also: the swimmer was a she, not a he.

    edit:

    wait I found it:

    Text transcription

    A series of Facebook comments.

    Claire Fletcher: He didn’t make it. Is he ok or he still swimming? [attached is a close-up of the path, showing that it ends some distance away from the coastline]

    Sophie Etheridge - Adaptive Athlete: Claire Fletcher I did make it, the GPS transponder was on my pilot boat but the beach was too shallow for it to come in close enough so instead my pilot launched the small RIB boat to accompany me to shore 🙂

    Melissa Dupree Haws: Sophie Etheridge - Adaptive Athlete wow! The real swimmer here! I’m so amazed at this feat of athleticism.

    Claire Fletcher: Sophie Etheridge - Adaptive Athlete omg the actual swimmer is here AND a she not a he! That’s amazing! What made you want to do it? Was it a personal goal or for charity? Full respect to you by the way, well done!👏🏻👏🏻👏🏻

    Robert Mothersole: Sophie Etheridge - Adaptive Athlete so while you’re here, if you dont mind me asking…Why didn’t you go straight ?

    Sophie Etheridge - Adaptive Athlete: Robert Mothersole I did, in the English Channel the tides move up and down rather than across so you get 6 hours up, then 6 hours down. I swam on a Spring tide, which is a bigger tide to start with and I’m not a super fast swimmer (around 2 min 15 per 100m). So i was pushed up the channel for 6 hours, then down the channel for 6 hours twice…so i was swimming forwards but going sideways, if that makes sense?

    Sophie Etheridge - Adaptive Athlete: Claire Fletcher its a long story…it was a personal, life changing goal, it raised money for charity and that money went to training swimming teachers to become specialist disability swimming teachers. If you want to know more then I write a blog and during the year of my channel training I documented my training each month. This is the first one explaining about me/how I got to where I was at the time - https://sophie-adaptive-athlete.com/…/2023-channel…/ If you scroll through my other blog posts I wrote multiple blogs about my actual swim too 🙂

    Claire Fletcher: Sophie Etheridge - Adaptive Athlete that’s truly amazing! Well done you! Should be very proud of yourself! I am going to binge read your blogs now with a cuppa lol

    Robert Mothersole: Sophie Etheridge - Adaptive Athlete it does make sense, it’s a bit different from the local swimming baths, thanks for your answer and congratulations on swimming the Channel. Brilliant achievement 👍

    Sophie Etheridge - Adaptive Athlete: Claire Fletcher hope you enjoyed them and your cuppa!

    Ok that’s some really interesting context I didn’t know. I’ve only ever seen it done the mathematician’s way with dx at the end. Learning physicists do it differently explains why the person in the post would want to discuss moving it around.

    But I still think they have to mean “if dx can be treated as an operand”. Because “if dx can be treated as an operator” doesn’t make sense. It is an operator; there’s no need to comment on something being what it objectively is, and even less reason to pretend OOP’s partner was angry at this idea.


  • You’re misunderstanding the post. Yes, the reality of maths is that the integral is an operator. But the post talks about how “dx can be treated as an [operand]”. And this is true, in many (but not all) circumstances.

    ∫(dy/dx)dx = ∫dy = y

    Or the chain rule:

    (dz/dy)(dy/dx) = dz/dx

    In both of these cases, dx or dy behave like operands, since we can “cancel” them through division. This isn’t rigorous maths, but it’s a frequently-useful shorthand.
