Chankillo is an ancient monumental complex in the Peruvian coastal desert, in the Ancash Department of Peru. The ruins include the hilltop Chankillo fort, the nearby Thirteen Towers solar observatory, and residential and gathering areas. The Thirteen Towers are believed to have been a solar observatory built in the 4th century BC. As of 2008, the culture that produced Chankillo is unnamed.

Einstein secret

James Dacey (physicsworld) is blogging on a new iconic image of Einstein, creation of Spanish artist Juan Osbourne. It is a game to find some hidden numbers.

The hunt for the elusive Higgs

"Physicists at CERN's Large Hadron Collider (LHC) are confident that they can find the Higgs boson by the end of 2012, when the machine will be shut down temporarily...The most sought after particle in particle physics – the Higgs boson – is believed to endow all other particles with mass. It is also the last undiscovered component of particle physicists' great theoretical framework – the Standard Model. After decades searching for the Higgs in particle collisions at CERN, and at Fermilab in the US, researchers at the LHC believe they may finally have the elusive particle within their grasp."

Thin film has 'astonishing' ability to rotate light

"Physicists in Austria and Germany have taken the Faraday effect to a new extreme by rotating the polarization of light by 45° by passing it through an extremely thin film. This "giant Faraday effect" could someday be used to create optical transistors that switch light or to improve terahertz imaging systems."

The teacher appears

But lo! the teacher Jizô appears,
All gently he comes, and says to the weeping infants:
"Be not afraid, dears! be never fearful!
Poor little souls, your lives were brief indeed!
Too soon you were forced to make the weary journey to the Meido,
The long journey to the region of the dead!
Trust to me! I am your father and mother in the Meido,
Father of all children in the region of the dead."
And he folds the skirt of his shining robe about them;
So graciously takes he pity on the infants.
To those who cannot walk he stretches forth his strong shakujô,
And he pets the little ones, caresses them, takes them to his loving bosom.
So graciously he takes pity on the infants.
Namo Jizo Bosatsu!

Jizo - matrix of the earth

Jizo was a bodhisattva (bosatsu in Japanese), a man who achieved enlightenment but forsaked nirvana to help others find paradise. He was worshiped  as the protector of those in distress, of children, of mothers in childbirth, and of travelers.  Worship of the bodhisattva Jizo began in the eighth century with the importation of esoteric Buddhist practices from China. Jizo, whose name means "matrix of the earth," was revered as one of the Eight Great Bodhisattvas of the esoteric sect. Jizo and his counterpart, Kakuzo ("matrix of the void"), represent the union of the physical and metaphysical realms.
The Jizo figure is defined by his clothing, by the objects he holds, and by his physical attributes. His head is shaven, and he is dressed in monk's robes, a simple rectangle of cloth (kesa) tied in front over a longer skirt. In his left hand, Jizo holds a wish-granting jewel; he would have held a shakujo (jingle-staff) in his right. The shakujo was used to alert insects and small animals of his approach, so that he would not accidentally harm them. Jizo's idealized face and head-the perfectly proportioned features, third eye, elongated ears, and folds of skin at the neck-also show attributes of an enlightened being.

Jizo Bosatsu



Il bodhisattva Jizo
Legno laccato e dipinto
Giappone, fine del periodo Muromachi, XV-XVI sec.

Jizo Bosatsu, il bodhisattva Jizo, è venerato in Giappone come colui che interviene a trarre i fedeli dagli inferni in cui possono essere caduti. Nell’iconografia del Buddhismo giapponese è ritratto nelle vesti di un monaco dalla testa rasata, munito del bastone del pellegrino e del “gioiello che esaudisce tutti i desideri”. L’assenza di corona e ornamenti è compensata dall’eleganza regale del manto e della tunica decorati con ricami dorati di ispirazione cinese e centro-asiatica. La statua faceva parte della collezione del barone Wilhelm von Bode.

Buddha assiso


Buddha assiso - Gandhara

Le figure sono ricavate all’interno di un arco. L’arco poggia su due lesene con capitelli che richiamano le foglie di acanto dei capitelli corinzi. Sui capitelli sono collocati due grifoni dalle code fiammeggianti. Il Buddha è assiso, la gamba sinistra piegata a terra e il ginocchio destro sollevato su cui poggia il gomito destro. La mano destra mancante era sostegno al volto inclinato in atteggiamento pensoso. Al disopra della spalla destra del Buddha si scorge la figura di Vajrapani che impugna il simbolo del fulmine di Indra. Il fregio alla base del pannello presenta scene dalla vita di Shakyamuni e la sua figura emaciata dalle pratiche ascetiche intraprese prima dell’Illuminazione.

Le sorgenti del Nilo

Nerone promosse nel 62, o 67 d.C., una spedizione per scoprire le fonti del Nilo. Fu comandata da due legionari, che risalirono il Nilo verso l'Africa equatoriale partendo da Meroe, vicino a Karthoum, l'attuale capitale del Sudan.

Leonardo's dream

"A research team at Festo has developed SmartBird, a biomechatronic bird that can take off, fly and land autonomously. Festo claims that SmartBird flies, glides and moves through the air like its counterpart in nature — the herring gull — with no additional drive mechanism."
