This author's style seems like was made for a manga adaptation of Nibelungen or Lord of the Rings. I mean, I haven't seen such cool mountain and forest backgrounds in a long time.

 

[Serenata]

I see now!

While crystal radios are classically made using pieces of galena for the semiconductor, pyrite offers the interesting advantage that, instead of moving the cat-hair to find a good contact point, one can simply alter the force with which the cat-hair is pressed to the pyrite.

Having the titles for what books to read more on is nice

Best chapter so far. It was fascinating to witness Ruri come to an understanding that even though some rocks like pyrite don't have significant monetary value, they have other unique aspects that make them worthwhile.

As a geologist, this chapter is the best so far--it rouses my geological mind. When Nagi was excited about the pentagonal dodecahedron pyrite (a.k.a. pyritohedron), I could feel the same excitement, because that small change in the geological map could mean something bigger. That pyrite form means it's the highest forming temperature a pyrite can have with a higher fluid saturation, which I can interpret as a closer heat source (magma/volcano) than was expected from that area. A closer source to magma means a higher chance for the true gold to form, as gold often forms near the top of an intermediate (dioritic) magma body. If they can finally find a locality that is dominated by pyritohedron pyrites, then they're probably quite close to a gold deposit.

Also, FYI, sometimes, even the fool's gold (pyrite) can have a trace amount of true gold, but it needs a high-tech extraction method.
