Thanks very much, especially to @hltn.bsky.social who helped me identify this for what it is :)

Historians of science: any thoughts on this? I'm intrigued by a "recipe" in a 1505 manuscript, which describes what appears to be the Leidenfrost effect, named after Johann Gottlob Leidenfrost, who supposedly was the first to describe the effect in the 18th century 🗃️ #HistSTM #HistSci #EarlyModern 🧪

The Leidenfrost effect! But wow is this ever an early description of it.
celinecamps.bsky.social
I'm still not doing it, haha.
celinecamps.bsky.social
I’ll take the author’s word for it!
celinecamps.bsky.social
Yeah, I won’t be reconstructing this recipe.
celinecamps.bsky.social
I’d say, give it go :)
celinecamps.bsky.social
I'd be curious to know if anyone has ever found an earlier description of this effect #MedievalSky #EarlyModern

Oh, I was not familiar with the concept! Thank you!
On a different page, the author also notes the same recipe for reaching into molten lead.

As the author assures us on the previous page, if you put your hands in cold water first, "so dünckt dich doch sey neurt loe" (it will only seem lukewarm to you).

A "recipe" from a 1505 manuscript:

"wiltü in hais pech griefn halt die hent wol in kalt wasser je kelt je peser dan grief dorein"

ENG: If you want to 'reach into' hot pitch, then hold your hands in cold water - the colder, the better - then reach into it

Any volunteers? 😳 #HistSci #EarlyModern 🗃️

Gosh, Thony, that's awful! I hope you get well soon. If there's anything I can do, don't hesitate to let me know. I'm not that far away.

I have a meeting with a curator coming up, who just sent me an invitation with the title "Schrauben und anderes" (screws and other things) and this just perfectly captures my life right now 🔩 #HistTech #HistSci #EarlyModern 🗃️

tagged me when you posted these pictures a few months ago. Thank you for reminding me, because now I can save them with the new bookmark function ❤️

This is helpful thinking, thank you! I've indeed been searching for them in assembled objects depicted in paintings, but I have had no luck so far, so these references are useful. Many thanks!

#SkyStorians, I'm looking for #MedievalSky and #EarlyModern paintings, engravings & other visual sources that depict screws.
(N.B. I'm not looking for depictions of screws in technical sources on this topic).
If anyone has come or comes across them, I'd love to know! #HistSci #HistTech #ArtHistory

A friend's applying for a postdoc which expects an extensive publication record. I've seen grad students who focus on publishing over developing their diss & the 1st thing that goes out the window is quality. Why do we glorify & celebrate "productivity" over quality? @academic-chatter.bsky.social
celinecamps.bsky.social
No problem at all. There's no rush :)
