Hi friends, for those of you using Koreader (Iโ€™m using it on a Kobo).

There are two very faint grey lines on the page, and I do not know what they are or how to get rid of them

Does anyone know how to turn them off?

The lockdown project for one of my parents neighbours was to build a scale model of the lake district from Lego. Itโ€™s now in the local museum.

Itโ€™s #BlackHistoryMonth so itโ€™s a good time to celebrate the extraordinary mathematician and NASA scientist Katherine Johnson (nรฉe Coleman; 1918 โ€“ 2020). One of the first Black women employed as a NASA scientist (& its predecessor NACA), she was known for her mastery of complex manual calculations of orbital mechanics & played a pivotal role ๐Ÿงต1/

@epiceneVivant for some amazing queer figure skating I also wholeheartedly recommend this ice dance program youtu.be/tCugp67NNmU?si=B83UUH

what I really hate though is how quizzes and test markings are locked after the first viewing or after a day. it's idiotic and inconvenient

I've really soured on the online courses I'm taking. The lack of engagement from my instructors is extremely annoying. At least in a physical school, I could stalk outside their office until they respond to me.

@izaya do you let other folks on your minetest server? I want to try it and maybe play with a friend

For #ArtAdventCalendar Day 13: Happy birthday to #mathematician Virginia Ragsdale (1870-1945). The Ragsdale conjecture, made in her 1906 dissertation, is amongst the earliest and most famous on the #topology of real & algebraic curves, which stimulated a lot of 20th century research & was not disproved until โ€˜79. A correct upper bound has yet to be found. In her dissertation she tackles the 16th of David Hilbertโ€™s famous 23 unsolved ๐Ÿงต1/n

Really great quote about leadership from Alexander Den Heijer, shared by @charrett: โ€œWhen a flower doesnโ€™t bloom, you fix the environment in which it grows, not the flower.โ€ #yowsydney #yow23 ๐ŸŒน

“This disorder, which was eventually called encephalitis lethargica or von Economo’s sleeping sickness, swept through Europe and North America during the second decade of the twentieth century; by the end of the following decade it had apparently disappeared, as only sporadic and unconvincing reports have appeared since. […] the virus that caused it was never identified

There was a passage in one of the Foundation novels where an armchair scientist described his doing science in terms of comparing the writings of various authors, and Salvor Hardin (I think) appraised the man's perspective on science negatively. I've always remembered that, and took on Hardin's attitude, but since I've actually had to do research...honestly, that's actually a lot of it. There is, perhaps, more effort that must go into systematizing one's own knowledge in parsing the various studies rather than just comparing the relative "authority" of the authors of different studies as I believe the armchair scientist was doing, but, significantly, it's not all just observation and experiment: there's theorizing that has to happen too, which depends on close reading and critically comparing results.

I'm not sure if I'm really arguing against anyone's actual perspective on how science is done here (I barely remember the passage from the novel in the first place.), but I just wanted to make a record of this way of thinking that I suppose has caused me a measure of embarrassment in years past about not being more hands-on in my research.

On the Origin of Species was published on this day in 1859, forever changing our understanding of nature and our origins. Here are the charming doodles Darwin's kids left all over his manuscript with their tiny opposable thumbs: t.co/BGtxu11Mgz
