Dodecahedral die

"In modern role-playing games, the dodecahedron is often used as a twelve-sided die, one of the more common polyhedral dice" http://en.wikipedia.org/wiki/Dodecahedron
http://en.wikipedia.org/wiki/Dice#Non-cubical_dice

Even in the past, the dodecahedron was used for dice.
Here an example form the site archéologique de la Cathédrale Saint-Pierre de Genève

CALCULI, COMPAS, DODECAEDRE

Very interesting page at http://www.alienor.org/Articles/ecriture/instrument3.htm
telling that "Les Gallo-Romains possédaient également différents instruments destinés aux disciplines scientifiques Pour compter, on utilisait des petits cailloux appelés calculi qui étaient placés dans des cases. On disposait aussi de compas se rapportant à la géométrie mais aussi au traçage des lignes d’écriture. ... Aujourd’hui, les avis convergent pour interpréter les dodécaèdres en bronze, creux, comme des instruments de géomètre."

Chimu Surveying

An Ancient Surveying Equipment of Chimu
The Chimu lives in the pre-Columbian Peru, struggling to survive in one of the world's driest desert.
They were therefore "hydraulic engineers". Some of their knowledge about the management of water came from their predecessors, the Mochica, who lived in the Peru's Moche Valley during the 1st millennium AD. Mochica built a network of canals to irrigate their fields. 

 Adapted from http://www.specialtyinterests.net/eop.html

This is a Chimu surveying instrument shows how calculate the slope of the land. "The device consisted of a ceramic bowl pierced by a hollow sighting tube passing through a calibrated, cross-shaped opening (inset). And artificial horizon was established by aligning water with the three dots in the bowl, which was leveled in a larger, sand-filled vessel atop a tripod (far left); when the sighting tube was in the center of the cross-shaped opening it was parallel to the artificial horizon. Chimu surveyors marked a rod at the height of the level sighting tube, then moved the rod a known distance along uneven ground and sighted the mark. The ground slope corresponded to the tube angle indicated by the calibrations inside the bowl." From

Surveying and Hydraulic Engineering of the Pre-Columbian Chimú State: ad 900–1450, Charles R. Ortloff, Cambridge Archaeological Journal, Volume 5 / Issue 01 / April 1995, pp 55-74
Abstract The Chimú state of northern coastal Peru (ad 900–1480) developed massive irrigation-based agricultural systems supplied by intricate networks of canals drawing water from river sources in coastal valleys under their political control. Further intervalley canal systems, some up to 50 miles in length, were constructed to shunt water between river valleys to augment intravalley supplies. A high degree of civil engineering skill was necessary to construct and maintain such complex systems; knowledge of surveying and of open channel flow hydraulics was paramount. Some of the technology used by the Chimú has been investigated: surveying instruments and calculating tools have been unearthed and analyzed to provide some understanding of the technical base used for canal design. Details of the hydraulics knowledge-base have been extracted from computer simulation of the functioning of ancient Chimú canal designs. This article assembles known pieces of information related to Chimú civil engineering practice and attempts to provide a plausible methodology that could have been implemented by the Chimú to survey the precise canal bed slopes necessary for proper hydraulic functioning of large canal systems through rugged Andean foothill and mountain areas.

Roman Dodecahedron of Kadath

The web site http://www.kadath.be/ is publishing the review Kadath. The site tells that it is based on the "projet KADATH". "Dans l’œuvre de H.P. Lovecraft, Kadath est la cité légendaire des Grands Anciens, symbole de l’origine des civilisations. Notre quête, appliquée aux réalités archéologiques, est de remonter à pareilles sources, en cherchant à déchiffrer l’empreinte que laissèrent les premiers civilisateurs, dieux et ancêtres présents dans tous les mythes et toutes les traditions."
the reader can find a paper from Kadath, written by Pierre Méreaux-Tanguy discussing the Roman Dodecahedron as an optical instrument. For other reference on the Roman Dodecaedron see the papers: Ancient and modern rangefinders at http://arxiv.org/abs/1205.2078 and http://arxiv.org/abs/1206.0946

Cooking ... the brain


"Brains demand exceptional amounts of energy," says Ed Yong at Discover Magazine — energy that raw food simply can't provide. That's where cooking comes in.
Writes Yong:
Our ancestors overcame this constraint when they learned how to cook. Cooked food offers more calories than raw food, and is easier to chew and digest. These early chefs could gain more energy from the same amount of eating time. That, in turn, fueled more neurons and larger brains.

Julius Caesar and the Parthian Wars

The previous post was on a book (in italian). In the fiction,  a time-traveler comes back from future in the Rome of 44 BCE, to save Julus Caesar's life. The book is entitled "The Parthian War".

Had Caesar ever been involved in Parthian Wars? Here from Wiki

"In 53 BC, Crassus led an invasion of Mesopotamia, with catastrophic results; at the Battle of Carrhae, the worst Roman defeat since the Battle of Cannae, Crassus and his son, Publius, were defeated and killed by a Parthian army under General Surena. The bulk of his force killed or captured; of 42,000 men, about half died, a quarter made it back to Syria, and the remainder became prisoners of war.[7] The following year, the Parthians launched raids into Syria, and in 51 BC mounted a major invasion led by the crown prince Pacorus and the general Osaces, but their army was caught in an ambush near Antigonea by the Romans under Cassius and Osaces was killed.[8]
During Caesar's civil war the Parthians made no move, but maintained relations with Pompey. After his defeat and death, a force under Pacorus came to the aid of the Pompeian general Caecilius Bassus, who was besieged at Apamea Valley by the Caesarian forces. With the civil war over, Julius Caesar elaborated plans for a campaign against Parthia, but his assassination averted the war. During the ensuing Liberators' civil war, the Parthians actively supported Brutus and Cassius, sending a contingent which fought with them at the Battle of Philippi in 42 BC.[9]

Roma. Anno 44 avanti Cristo, mese di marzo. Da un futuro lontanissimo in cui la scienza ha raggiunto vertici inimmaginabili, ma insanguinato da una guerra cruenta, appare nell'Urbe un misterioso personaggio. E' un viaggiatore del tempo dotato di straordinari poteri. Nessuno saprà mai qual è la sua vera identità, si fa chiamare Sesto Mercurio e con questo nome verrà ricordato negli annali dell'Impero. Ha una sola missione da compiere: salvare Caio Giulio Cesare dall'imminente attentato delle idi di marzo. ...

Cupriavidus metallidurans

"The ability to create gold from base materials has eluded alchemists since the Middle Ages, but two U.S. university professors have found a way to produce small amounts of gold using metal-loving bacteria to make the magic. ... the two professors at Michigan State University found that a certain type of metal-loving bacteria can transform high amounts of the toxic chemical compound gold chloride from a liquid into solid 24-karat gold. " Kazem Kashefi, assistant professor of microbiology and molecular genetics at Michigan State University and Adam Brown, associate professor of electronic art and intermedia at Michigan State, found that the bacteria, Cupriavidus metallidurans, can withstand concentrations of gold chloride 25 times higher than previously reported by scientists.

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.

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

The legend of Cangjie

After unifying China, the Yellow Emperor, being terribly dissatisfied with his Quipu method  of recording information, charged Cangjie of creating characters for writing. Cangjie then settled down on the bank of a river, and devoted himself to the completion of the task at hand. ... One day, Cangjie  saw a phoenix flying in the sky above, carrying an object in its beak. The object fell to the ground directly in front of Cangjie, and he saw it to be an impression of a hoof-print. Not being able to recognize which animal the print belonged to, he asked for the help of a local hunter passing by on the road. The hunter told him that this was the hoof-print of a Pixiu. This conversation with the hunter greatly inspired Cangjie  ... From that day forward, Cangjie paid close attention to the characteristics of all things, including the sun, moon, stars, clouds, lakes, oceans, as well as all manner of bird and beast. He began to create characters according to the special characteristics he found, and before long, had compiled a long list of characters for writing. To the delight of the Yellow Emperor, Cangjie presented him with the complete set of characters.

Ancient solar observatories: Syrian desert

The Syrian desert is covered by ancient stone structures created during Neolithic times, as I discussed in the paper, Stone circles on the harraat of Syrian desert, published at http://arxiv.org/abs/1106.4665
Some of these stone structures are circular, with radial lines of stones. These circles have been also compared with Stonehenge. Therefore, we can ask ourselves, are these solar observatories too, as Stonehenge is.
The answer is probably so, see my paper at http://arxiv.org/abs/1208.2591
I used a software for the solar energy applications to see the direction of sun on sunrise and sunset of solstice. It seems that there is a good agreement. Therefore, the Syrian stone circles are probably the Stonehenges of Middle East.

This is one of the stone structure of Syrian Desert. 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/. On the left, the site as it appears in the Google Maps. In the middle, the direction of the sun on the summer solstice, choosing the center of the circle for observation. We see that, at sunrise, the sun is passing near the dot. At the sunset the direction is that of a line. In the image on the right, we see the direction of the sun on winter solstice. At sunrise, the lines is passing between dots. The sunset has the direction of a radius (images have been obtained from original provided by Google Maps and sollumis.com).

Circles and lines!
Alignemnt at the sunrise on the winter solstice


At the site http://www.dp-news.com/en/detail.aspx?articleid=97188
it is told that "He (David Kennedy) explains that they come in a huge variety of forms, some being ‘kites’, structures that funnelled animals, some being seemingly random meandering lines of stone and others being rectangular. None are believed to be aligned with the stars, which has added to the mystery surrounding their purpose." Well, in my opinion it is not so.

Do dolphins think nonlinearly? - physicsworld.com

Do dolphins think nonlinearly? - physicsworld.com
"Unlike solid objects such as the sea floor or fish – which reflect acoustic signals linearly, as straight-forward echoes – bubbles reflect nonlinearly. This means that acoustic echoes from bubbles contain harmonic frequencies in addition to the fundamental frequencies of the outgoing signal – producing a "clutter" that is incredibly confusing to sonar. And to make matters worse, bubbles are extremely efficient at reflecting sound."

Silicene

Silicene pops out of the plane - physicsworld.com
"Researchers in Japan say that they have made 2D honeycomb crystals of silicon that resemble the carbon-based material graphene. This is the second potential sighting of the material dubbed "silicene"; the other was reported in April by an independent group in Europe. The Japanese research suggests it may be relatively easy to alter the structure of silicene by changing the substrate on which it is grown – which could allow different versions of silicene to be produced with a range of useful electronic properties. However, not all scientists agree that this latest material is actually silicene."
