Looking for a reference/primer/explanation on discriminant diagrams, as one does, I stumbled upon this excellent resource, which opens:
You, too, can be a geochemist! You will never have to look at another rock or mineral again! Your only tenuous links to reality will be tables of numbers and vials of powder by post!

Many years ago, I remember going to a one-off planetarium show which included a song called "The Astronomer's Lament", of which I can remember nearly all of the refrain:

I never see stars, even when it's clear,
I only see [a bit I forgot] and paper up to here.
I never see stars, any size or shape,
I only see computers and a million miles of tape.
I see cars, bars, lots of seminars,
I see the bloody freeways, but I never see the stars!

Today I learned
a) that there exists a unit of measurement called a barn, and
b) right before I was going to crack a joke about the name, why it was named that (rendering any joke I could make redundant)

(The Wikipedia spiral that led to my acquiring this information went something like MRI > MRA > MRI contrast agent > Gadolinium > Barn. Gadolinium comes from the Hebrew 'gadol', great, and has nothing to do with gladioli.)

It is both comforting and disturbing to encounter someone who clearly understands your field enough that they can make such ha ha only serious kinds of statements.
