Former geology student here. There's far, far too little geology on TH-cam!
I hope to add some more in time!
As geologist, I love these geological videos 😍
Sono contento! Devo farne altri.
@@polyMATHY_Luke Non vedo l'ora! Anche se ho ancora gli incubi su geologia metamorfica 😂
What a charming exchange 😊
I grew up near Chestnut Hill and my grandfather emigrated to this country from Friuli, Italy to work this stone. Mandi and grazie Polymathy for producing this video.
Mandi! Grazie mille. Che bel racconto!
No matter if it's a language-related video or something completely different, you have your own way to keep our attention and make us wanna learn new things!! You're πολυπράγμων! That's the first word in my languagethat came in my mind and depicts you!
That’s very kind, thanks for watching!
You’ve got to be schisting me!!
You stole my comment haha
As a trained geologist, I approve of as many metamorphic puns as possible.
@@polyMATHY_Luke
Of quartz.
Now be gneiss!
@@polyMATHY_Luke That's very gneiss of you.
I heard your cummingtonite video will be getting released soon?
(ok that last one doesn't work very well, but you try making a pun with cummingtonite... it ain't easy!)
I'd love to see more geology content. I have no real knowledge about it at all, but I've slowly picked up an interest in it from trying to incorporate plate tectonics into my worldbuilding (and being from Iceland doesn't hurt either). Grātiās tibi agō, Lūcī!
I endeavor to create a full intro geology course in videos in the next few years!
Thanks for posting Luke!👍
Thanks for watching!
You should look up the Schist Villages of Portugal (Aldeias do Xisto), gorgeous ancient houses built entirely of schist in beautiful mountain range environments (and they have some great food too). Probably based on a tradition dating back to the pre-Roman Celtic era. Well worth a visit.
Sounds great!
Hey, you're back in America. In PA, no less. My wife was born and raised in Sunbury, in the north-central part of the state. She's been to Philly on many occasions. 🙂🙂🙂🙂
Gotta love them rocks. Also gotta love the energy to these geology vids. Would love to see a video on chert/flint one day -- not a lot of content out there in the overlap between geologists, scholars of classical culture, prehistoric Mediterranean and Classical archaeologists.
Do Latin or Greek texts ever refer to flint? Rummaging through boxes of the stuff excavated from Roman sites near Villafranca di Verona, or Hellenistic sites near Athens; it's of course not systematically knapped or worked (apart from the Neolithic artefacts found and kept by the people of antiquity of course!) but there's clearly some form of use, or relationship to this most funky of stones -- even if just throwing it into fire!
Just a fun thought inspired by the video.
Great suggestion!
Holy Schist!! This was very informative.
This is a great concept, a Latin scholar explaining natural sciences like geology which get much of their naming conventions from classical languages like....Latin. Helps a lot when you learn the meaning, eg, Palustris refers to swampy areas so when you see a Pine tree with that name, well, you learn where you should expect to find them.
American houses are a lot different than the italian ones. I enjoyed your explanation. Waiting for another interesting video. Grātiās tībī agō!
Grātiās quod spectāstī!
Caro Luke, ti seguo da tanto tempo ed è molto bello vedere ogni volta che ci gratifichi anche con le tue conoscenze geologiche e non solo linguistiche, tanto più che la geologia è una scienza che mi ha sempre affascinato (in particolare le rocce metamorfiche!), contro ogni aspettativa dei miei amici, visto che in realtà sono specializzato in settori umanistici come la linguistica e i testi medievali. 😄 Ma è una scienza magica! Ci starebbe quasi di dedicare una playlist solo alla geologia!
Ciao! Grazie mille; ne sono d’accordo, è una scienza meravigliosa! Ne farò di più. Valē
This video is the schist!
Shiny rock, lovely
Geology *and* etymology! Two of my favorite subjects! =^[.]^=
You’re my target audience! Awesome
@@polyMATHY_Luke Are you going to do any more astronomy videos? I'd LOVE to see an etymology video about the objects of the solar system!
@@polyMATHY_Luke Etymology is particularly interesting, because it combines elements of history, sociology, and psychology. One of my favorite books is by Bill Bryson, "The Mother Tongue: English, and How It Got That Way." It is an excellent and most entertaining read, which explores all of those elements. =^[.]^=
Love the video! Thanks for being so interesting!
Really nice villa with a a cute little pronaos.
More good work from Luke. I've always mispronounced schist as skist, by analogy with schism, standardly pronounced as skizm.
I would argue your pronunciation is more correct; I also prefer schedule as /sk/, unlike the usual British pronunciation
In Catalan we have the word "mica" which means "a little bit". Also from Latin "mīca".
Thank you, from NYC, where the Bronx is gneiss and Manhattan is schist.
The material between the stones there is interesting too. It sometimes looks as if it were not just the usual mortar, applied as a thick liquid and then solidified, but something with its own preferred solid shape that's just wrapped around the stones, like flatbread around meat & veggies.
Very observant!
It’s amazing all the stuff I took for granted like this, I wonder if there are headstones made of this stone somewhere
Muscovite was named after its use as window glass in Russia during medieval time. There's an actual chemical reaction that occurs in its transformation from biotite to muscovite. After many college geology tests, someone would never fail to mention what a suck schist test it was. Thanks for the thoughts...✨️
That's right! I forgot to mention that cool fact.
Nice stache
so many english words/terminology i never heard and used before :-D
Luke -- so, how do we KNOW that this is how schist was formed? You mentioned they were in riverbeds -- rivers became mountains? Also, congrats on getting through that many utterances of 'Schist' without a flaggable screwup.
Haha. I put some of the flubs at the end; there were many more.
So the mineral composition is consistent with a sedimentary origin of this type. The Taconic orogeny piled huge amounts of mass overtop, and then later those mountains were completely eroded away, revealing to us the schist.
Saxis! Lapis Magnus 🪨👍🏻 Gratias Lucas
this man can do everything?! literal icon we stan. local to me is phyllite that's between 600million to 1 billion years old, so that's fun. most everything here is granite though, so much granite, s o m u c h g r a n i t e
Heh that’s nice of you; actually my first degree is in geology, so this is nostalgia for me. Pre-Cambrian phyllite is the bomb; I take it you’re in the continental interior?
@@polyMATHY_Luke southern new england actually, there's some small fragments from presumably the avalon continent iirc, besides all the granite
i found a piece of mica by the train tracks one time
schist happens
I was going to say, I'd have a hard time believing someone if they said the house was only 100 years old!
Iawn ! My particular interest in geology beyond the raw rock is in how it modifies or attracts human behavior,. Currently I live where the Llech/ slate begins in Eryrie Cymru. Copper mountains with silver and lead 15 miles south and gold 15 miles north. a very different energy from the Ironstone rock I lived on in the south. When I visit the coast 10 miles away there are many colours of slate on the beach some with fern fossils but also granite and milky quartz from other areas. But maybe the most interesting coastal phenomenon is the sunken forest Cantref y Gwealod where recent storms revealed fossil trees and footprints of children from 6,000 years ago just after the ice retreated .
Beautiful your land!
Please do something on las medulas it is such a crazy site and all that washed out silt must have influenced land fertility
I'll look into it
I always had a doubt about Luke but I am now certain he is a sophist.
Lol I hope you mean the first paragraph here and not the second: en.m.wikipedia.org/wiki/Sophist
@@polyMATHY_Luke Neither. The sophists were a type orators (in ancient philosophy) who could say everything and the contrary of everything convincingly. The archetype of lawyers if you will. Opposed to Socrates who thought truth was only one and could be find with logic. fr.wikipedia.org/wiki/Sophiste
3:42 is the German Schicht (layer) a cognate of schist?
polymathy, what are your thoughts on 'caesar completely parsed', do you think latinists should make more books like this for beginners? Or for intermediate students who want to expand vocabulary.
Or I even had the idea to use interlinear lines in latin songs and hymns (for those who want to know what they're singing)
Ultimately, any tool that aids the learner is a good thing. I have found explicit grammatical explanations very helpful, especially after the beginner or intermediate level. I tend to recommend input based approaches as much as possible otherwise.
I’m not familiar with that text, but interlinear translations are super helpful; I prefer them to page by page translation.
Extremely interesting.
150-200°C? Is there, maybe, a zero missing from those two numbers?
Apart from that, another etymological relation - Schizophrenia. Is the English pronunciation of the zeta influenced influenced by German?
Yes, the term schizophrenia is actually a German coined phrase.
Thanks for the comment! The temperature is right as the lower limit of metamorphism. I believe you're right that German influenced the pronunciation of schizophrenia, while French influenced the pronunciation of schist.
Mica mica stellula
Miror quid sis natura
0:32 funny. Luke realized he used the European three then changed it to amurrican?
It’s sort of a running joke; I am aware of this distinction so I find myself wanting to do both
Plymouth-y
Are those schist rocks the same rocks of shale gas from fracking?
It's possible one could find strata of schist and gneiss in the vicinity of shale, as these are all metamorphic rocks. But I would hazzard to guess that they would not be plentiful in situ.
Look at the latin in Wednesday the Netflix show ..somthings not right with it
Hey, hai mai visto un video di geopop? Se si cosa ne pensi?
Sì, ne ho guardati tanti. Per lo più guardo i video dal canale di Zeihan perché sono più informativi.
Schist means Schiefer in German and actually shiver in English. Is the pronunciation a result of sch in schist?
Yes! The English pronunciation is taken from the French geological term schiste. French will occasionally turn Greek sch into a “sh” sound, as happens in British “schedule”
@@polyMATHY_Luke interessant. Merci beaucoup. 🫂
How are things?, thank you. unusual uploading!see you later- polýMAHY.✨
Thanks so much for watching. Not really; the polýMATHY channel covers all topics that interest me, including science.
