Schists and their shiny origin

Показать описание

Why are so many houses in Philadelphia sparkly? What rock are they made of? What is a schist? What's the difference between a metamorphic rock, a sedimentary rock, and an igneous rock? These questions and more will be answered in this geology field trip!

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.

As geologist, I love these geological videos 😍

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!

Former geology student here. There's far, far too little geology on Youtube!

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!

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.

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.

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.

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!

Love the video! Thanks for being so interesting!

American houses are a lot different than the italian ones. I enjoyed your explanation. Waiting for another interesting video. Grātiās tībī agō!

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.
