A board game!
Games agricolaites play: how do you extract the center atom without breaking any line? A possible answer – bring in more atoms like in the right-side structure?
I also inserted a new element – the “free” atom is actually a picture of planet Europa I found on RobertLovesPI blog page. Great picture! Now the new symbolic could be – when nano-scale agricolaite atoms break free, they reconstitute as a full-size planet in the sky. Quite a poetic journey indeed!

I’m not sure why – I had to introduce a soliton in this image. Nothing to do with the Agricolaite geometry, but somewhere the mirrored triangles & spheres remind me of this strange self-contained mathematical sound wave. A musical mineral? Why not!

“Bohemian pachinko” – study for a virtual 3D gallery exhibit piece.
From a resource by Anderson, Chieh, Irish and Tong. Incidentally, I used the same resource template I used on 07/16. Two versions of the same info with a 3-days hiatus.

What to do with so many atoms flying at your screen? Let them be I guess.
I noticed it before – the smaller the crystal, the more atoms in its structure. And of course like in every overpacked structure, it creates a stressed-out geometry and a huge array of vertices crisscrossing and overlapping each other. Hard to make sense of it all.

To stay with minerals named after famous people, I’ll study the Agricolaite this week, a Bohemian crystal named after Georgius Agricola. Georg Bauer (Agricola in Latin) was a German scientist from the mid-1400’s that many call the “father of mineralogy” because of the many books he wrote on the subject.
Agricolaite is a yellow green, monoclinic crystal of symmetry B2/b. It comes in tiny, microscopic clusters. Its geometry makes its core triangle pattern somehow look like a soliton, a unique, self-contained mathematical figure.
So far, Agricolaite has only been found in central Europe. It has been located, identified and approved as a unique crystal in 2010.
Not related, there is also a famous Central Europe board game called Agricola. It is a resource management game. Something the Agricolaite had to face too being that small in the larger mineral universe!

And to end the week with some grateful recognition for the author, here is a book from Goethe along with the tangram-like silhouettes of the Goethite crystal structure.
I’m not a great friend of the “theory of color”, I didn’t read “the metamorphosis of plants”, but this little crystal named after him was a pleasure to work with.
