Mombracco e Leonardo da Vinci

"Monbracho sopra saluzo sopra la certosa un miglio a piè di Monviso, a una miniera di petra faldata la quale e biancha come marmo di carrara, senza machule che è della durezza del porfido o più, delle quali il compare mio Maestro Benedetto scultore a impromesso donarmene una tabuletta per li colori.
 Adì 5 di genaro 1511", Leonardo da Vinci, manoscritto “B” Archive National Paris

http://it.wikipedia.org/wiki/Monte_Bracco


Here in the satellite map, the quartzite quarry on the top of Mombracco, a mountain near Saluzzo.
Leonardo da Vinci, as we can read from his words,
knew the white marble-like stone coming from this quarry.
Mombracco is a  is over Rifreddo, Sanfront and Barge.


« C'era amianto dappertutto, come una neve cenerina: se si lasciava per qualche ora un libro su di un tavolo, e poi lo si toglieva, se ne trovava il profilo in negativo; i tetti erano coperti da uno spesso strato di polverino, che nei giorni di pioggia si imbeveva come una spugna, e ad un tratto franava violentemente a terra. »
(Primo Levi, Il sistema periodico)


L'Amiantifera di Balangero è una cava di amianto situata in provincia di Torino, non più attiva. Fu la più grande cava di amianto in Europa e una tra le prime nel mondo; copriva una buona parte dei territori comunali di Balangero e di Corio.

Crean memoria de cristal capaz de guardar datos por millones de años
(ConNuestroPeru) "La información se podrá leer con la ayuda de un microscopio óptico. La empresa japonesa Hitachi ha presentado un prototipo de almacenamiento digital de información consistente en pequeñas láminas de cristal de cuarzo capaces de guardar datos durante millones de años."

Is it forming a new tectonic plate?

(CBS News) "A new study suggests that two recent earthquakes may indicate a literal seismic shift in our understanding of tectonic plate movements. Massive earthquakes under the Indian Ocean that took place last spring are the largest of their kind ever recorded. The 8.7 magnitude quake, followed by a 8.2 magnitude aftershock, could signal the formation of a new plate boundary under the Earth."

Lycanthropus, by C. EDGAR BOLEN

The jellied night has oozed its miry black
From out the hills to fill the valley floor.
Atop the ragged hills the torn cloud-wrack
Is lightning-limned into a hellish door.
A gust of wind across the sky is hurled—
The gods of old are loosed upon the world.

Age-old, the blood-lust wells within my throat;
Tensely I wait, and feel my body shrink;
My hairless hide becomes a furry coat.
Blood-hungry, through the opened door I slink;
I raise my head and howl in horrid glee—
And from the plain a howl comes back to me.

When America discovered Europe

A very remarkable book this one
The American discovery of Europe,  By Jack D. Forbes
 Let me suggest the reading of it. To stimulate the curiosity, here some small abstracts

What is Cornelius Nepos telling? And Pliny?



The world's first seismometer was Chinese


Who was the inventor of the first siesmometer?
 Zhang Heng. He was  (AD 78–139) a Chinese astronomer, mathematician, inventor, geographer, cartographer, artist, poet, statesman. He lived under the Han Dynasty (AD 25–220) of China. He was a  Chief Astronomer, Prefect of the Majors for Official Carriages, and then Palace Attendant at the imperial court.  He invented the world's first water-powered armillary sphere,  improved the inflow water clock by adding another tank and invented the world's first seismometer, which discerned the cardinal direction of an earthquake 500 km away. He improved previous Chinese calculations of the formula for pi. In addition to documenting about 2,500 stars in his extensive star catalogue. Some modern scholars have also compared his work in astronomy to that of Ptolemy (AD 86–161). (Adapted from Wiki)

 A replica of an ancient Chinese Siesmograph  (25-220 CE). Picture taken in July 2004  at Chabot Space & Science Center in Oakland California.
"In 132 CE, after several serious earthquakes in China, astronomer Zhang Heng invented this instrument to warn people of the next one. When the ground shook, it moved a pendulum inside the jug. The pendulum pushed a lever that opened one dragon's mouth. A ball rolled out and into the toad's mouth below, sounding an alarm. The open dragon mouth pointed in the direction of the earthquake, notifying the Emperor."

Ancient solar observatories: Stonehenge





This is Stonehenge. The image shows directions of sun during the day. “The lines on the drawing show the direction and height (altitude) of the sun throughout the day. Thicker and shorter lines mean the sun is higher in the sky. Longer and thinner lines mean the sun is closer to the horizon”, according to Sollumis.com http://www.sollumis.com/. The site is located in the Google Maps. The direction of the sun is given on the summer solstice, choosing an altar at the circle for observation. We see that, at sunrise, the sun is passing near the stone outside the circle.

The qocha of Chuquiña

Chuquiña is a small town in Bolivia.
Near Chuquiña satellite maps show a huge "qocha".
A "qocha" (small lake, lagoon)  is an artificial pond used to gain water for cultivation.
Waru-warus, camellones, qochas were old pre-incaic cultivation techniques.

Our Starman

Didn't know what time it was and the lights were low
I leaned back on my radio
Some cat was layin' down some rock 'n' roll 'lotta soul,  he said...
Then the loud sound did seem to fade
Came back like a slow voice on a wave of phase
That weren't no D.J. that was hazy cosmic jive

There's a starman waiting in the sky
He'd like to come and meet us
But he thinks he'd blow our minds
There's a starman waiting in the sky
He's told us not to blow it
Cause he knows it's all worthwhile
He told me:
Let the children lose it
Let the children use it
Let all the children boogie


I had to phone someone so I picked on you
Hey, that's far out so you heard him too!
Switch on the TV
we may pick him up on channel two
Look out your window I can see his light
If we can sparkle he may land tonight
Don't tell your poppa or he'll get us locked up in fright

Starman, by David Bowie


Our Starman, farewell
