10-22. Celestine #1.

Cyrilovite, Celestine – minerals come in nice and exotic names sometimes!
Celestine, – or celestite as it is also called, is a playful mineral often found trapped in geodes. Which is strange since it gets its name from Latin – Celestis or sky.  Maybe it’s bluish glow, or maybe because the strontium in it is used in fireworks?

Celestine can be found in small quantities, pretty much all around the world. Its crystal belongs to the orthorhombic system and its symmetry is Pnma. The biggest one so far is 18 inches wide and weigh 300 pounds. A piece of the sky fell to earth!

Its chemical profile is SrSO4. So, here is a Celestine Haiku, thanks to the ingenious periodic table of scientist and poet Mary Soon Lee.


I strive for indépendance
Sweet days are long gone
Yet, I still can’t spell your name

10-15. Cyrilovite #1.

A Cyrilovite from Cyrilov, Moravia – that’s a poetic and mysterious sounding name to start this week’s exploration of the geometry of Nature. Yellow to green, transparent to brown, Cyrilovite has a tetragonal structure with a P4 symmetry. It was discovered in 1953 in the Czech Republic.

Some say it carries with it a notion of respect, honor, and compassion. Are minerals projecting their properties onto humans or are humans projecting their wishes in minerals?

Well fitting with this week’s info background, a dear friend of mine sent me a link to a wonderful Chem-Haiku site. So here is the haiku of the week based on the chemical composition of the Cyrilovite. Thank you Mary Soon Lee for making the Periodic table so poetic and thank you, Tatiana, for being such a resourceful muse!

Racing to trigger
every kiss, every kind act,
Servant, friend and partner

Radiant child
most of me is you
fundamental, essential.

Water, life.
Fuel for the stars





09-12 – Chiolite #3.

Humor or surrealism – the geometry of Nature sometimes lends itself to strange visualization: this could be the original octahedra factory – chiolite creates octahedra, collect them in its structured drawer/cubes and delivers them to the world as beautiful geometry figures.

Of course, this is not true – but the geometry of this chiolite carries some disconcerting and beautiful mathematical poetry.
