If we zoomed in to see the aluminum, silicon, and oxygen atoms, kyanite would look like this... and andalusite would look like this. I'm only showing a few thousand atoms here, but these patterns continue for hundreds of millions of atoms. It's quite pretty. But, I want to ask: how would you describe the way these atoms…
