Geology

As someone who does a lot of technical writing this is a real struggle. They call it knowledge basis. Basically you have to know what your target audience knows. Write it too high and people will get lost and not read it. Write at too low of a level and people will get bored and stop reading.

Best way to cure yourself of this is to become a teacher in your field, especially if you do any teaching of anybody who isn't already specializing in it (K-12 or for-non-majors college classes). I'm a music teacher and yesterday I had a kid struggle for a full half hour to play a kick drum on a consistent quarter beat. Literally all you have to do is lift your foot up and put it back down again, but at one point he actually asked me "when I pick my foot up, it keeps hitting the bit of the kick pedal above it and that's throwing me off" and I had to explain to him that he could move his foot half an inch backward and that would stop happening, because apparently he was unable to intuit that. Didn't seem to help him all that much, though.

He was also wearing running shoes with the laces taken out, which leads me to believe that this is not the only basic thing this ten-year-old child struggles with.

Sorry, I know this isn't geology related, but I needed to rant about it.

Of quartz

Studying history I am immune, because it is obvious that people don't care.

They take their knowledge of geology for granite.

TIL that ‘feldspar’ is an actual thing and not just a silly name they used in Outer Wilds. Actually, looking it up, all of the Traveler’s names refer to rocks or minerals (Feldspar, Gabbro, Riebeck, Chert, and Esker). Interestingly, Solanum refers to a plant instead (a plant of a genus that includes the potato and woody nightshade).

Olivine: (Mg,Fe)2SiO4.
Feldspar I: KAlSi3O8.
Feldspar Ii: (K,Na)AlSi3O8.
Quarz: SiO2.
Apparently Quartz is the second most abundant mineral in Earth's continental crust, behind feldspar.

I can maybe remember Quarz.
