Two splendid suns

"Earth could be getting a second sun, at least temporarily. Dr. Brad Carter, Senior Lecturer of Physics at the University of Southern Queensland, outlined the scenario to news.com.au. Betelgeuse, one of the night sky's brightest stars, is losing mass, indicating it is collapsing. It could run out of fuel and go super-nova at any time.
When that happens, for at least a few weeks, we'd see a second sun, Carter says. There may also be no night during that timeframe."

Fotovoltaico organico

Come celle solari organiche si intendono quei dispositivi la cui parte fotoattiva è basata sui composti organici del carbonio, includendo anche quelle celle più prettamente di tipo ibrido. La struttura base di una cella organica è un "sandwich" composto da un substrato e da una o più sottilissime pellicole contenenti i materiali fotoattivi, in mezzo a due elettrodi conduttivi di cui uno trasparente.
"La gamma di celle solari organiche è ampia e si trova in diversi stadi di ricerca e di maturazione tecnologica e comprende, in sintesi, le celle “dye sensitized” (o DSSC), le celle totalmente organiche (anche dette plastiche), e le celle ibride organico/inorganico. Per le celle DSSC (o di Grätzel, dal nome del loro inventore), la parte fotoelettricamente attiva, spessa qualche micrometro ed inserita tra due elettrodi, è costituita da un pigmento organico, da ossido di titanio e da un elettrolita. Le celle DSSC, ispirandosi al processo di fotosintesi clorofilliana, utilizzano una miscela di materiali in cui un pigmento assorbe la radiazione solare e gli altri componenti estraggono la carica per produrre elettricità. Infatti è possibile ottenere l’effetto fotovoltaico anche con pigmenti vegetali. Efficienze massime del 10-11% e tempi di vita di vari anni, valori comunque in costante aumento, sono stati misurati in laboratorio per questo tipo di cella singola, utilizzando pigmenti sintetizzati attraverso i processi della chimica organica. ...
Le celle fotovoltaiche completamente organiche, sia quelle a “small molecules”, realizzate attraverso un’evaporazione sotto vuoto, sia quelle polimeriche, realizzate attraverso deposizione in forma liquida, sono recentemente arrivate al 4-5% di efficienza massima per celle in laboratorio. Queste celle, anche conosciute come “plastiche”, sono molto interessanti in quanto le tecniche di fabbricazione sono le più semplici da attuare."

Drilling for geothermal energy

"An exploration team in Newcastle plan to drill through old mining tunnels to search for geothermal energy under the city centre. Researchers from Newcastle University who are leading the project hope it could initially provide up to 5MW of thermal energy, with potentially more heat and electricity from future boreholes. This would provide heat for a new campus that will combine research facilities with affordable housing, while some energy may be siphoned off the power a nearby shopping centre."

The 3D light for spintronics

"Circularly polarized light, which is used in 3D movies, has its electric field vector rotating like a clock hand. It's typically produced by sending light through a filter, but now a team has created a small, solid device that emits partially circularly polarized light, as they describe in the 4 February Physical Review Letters. If this semiconductor technology can be further perfected, it could be used in devices that help biochemists control protein synthesis or help physicists control electrons in spintronics--a futuristic type of electronics."

The Eye of Osiris

"The Eye of Osiris" is a novel written by Richard Austin Freeman (1862 - 1943). He was a British writer of detective stories, mostly featuring the medico-legal forensic investigator Dr Thorndyke. A large proportion of the Dr Thorndyke stories involve genuine points of scientific knowledge, from areas such as tropical medicine, metallurgy and toxicology. In this crime novel, Dr Thorndyke solved the mistery using a X-ray photography of a mummy.

"It was all clear enough so far. The peculiar sound that filled the air was the hum of the interrupter; the bulb was, of course, a Crookes' tube, and the red spot inside it, the glowing red-hot disc of the anti-cathode. Clearly an X-ray photograph was being made; but of what? I strained my eyes, peering into the gloom at the foot of the gallows, but though I could make out an elongated object lying on the floor directly under the bulb, I could not resolve the dimly seen shape into anything recognisable. Presently, however, Dr. Norbury supplied the clue. 'I am rather surprised,' said he, 'that you chose so composite an object as a mummy to begin on. I should have thought that a simpler object, such as a coffin or a wooden figure, would have been more instructive.' "

Eye of Horus

The Eye of Horus is an ancient Egyptian symbol of protection, royal power and good health. The eye is personified in the goddess Wadjet. The name Wadjet is derived from 'wadj' meaning 'green' hence 'the green one' and was known to the Greeks and Romans as 'uraeus' from the Egyptian 'iaret' meaning 'risen one' from the image of a cobra rising up in protection. More at Wiki
Wadjet was one of the earliest of Egyptian deities who later became associated with other goddesses such as Bast, Mut, and Hathor, who is also depicted with this eye. Burial amulets were often made in the shape of the Eye of Horus, to protect the owner in the afterlife and to ward off evil. Ancient Egyptian and Near Eastern sailors would frequently paint the symbol on the bow of their vessel to ensure safe sea travel (Charles Freeman, The Legacy of Ancient Egypt, Facts on File, Inc. 1997. p.91).
"Horus was the ancient Egyptian sky god who was usually depicted as a falcon. His right eye was associated with the sun Ra. The eye symbol represents the marking around a Peregrine Falcon's eye that includes the "teardrop" marking sometimes found below the eye."
It is interesting to note that, in the ancient egyptian calculus, the Eye Of Horus defined number one (1) = 1/2 + 1/4 + 1/8 + 1/16 + 1/32 + 1/64, by throwing away 1/64. The parts of the Eye were used to represent fractions.

Second sight

In English, "second sight" indicates a form of extrasensory perception - a supposed power to perceive things that are not present to the senses - by means of which a person gains information in the form of a vision. The person "sees" future events before they happen (precognition), or  things  at remote locations (remote viewing). "Second sight" is so called because normal vision is coming as first, while supernormal vision is a secondary thing, confined to certain individuals.

In Italian, we call it the "doppia vista", that is the double sight, physical and spiritual. It is considered an  awakening of consciousness.

Ecco una divinita' solare mesoamericana (cultura Chupicuaro), che con i suoi occhi raddoppiati evoca il dono della "doppia vista". Il giallo, colore del Sole, simboleggia la perfezione spirituale ed è specifico dell'intelligenza; è stato spesso usato negli oggetti di culto e magici. Bella statuetta che illustra chiaramente il concetto della doppia vista.

Arabia: craters and stone circles

The Arabia Shield has a volcanic nature inside. A region of the Western Saudi Arabia is in fact covered with vast fields of lava known as harraat. These lands are spotted by many stone circles and other quite interesting archaeological remains of the Neolithic period, such as the "desert kites", the hunters used to guide the game across the harrah in some corrals. With Google Maps, we can observe both sceneries, the volcanic nature of the land and a portrait of Arabia during the Neolithic times.

Woodhenge

Woodhenge is a Neolithic henge and timber circle monument located in the Stonehenge World Heritage Site in Wiltshire, England. Woodhenge was identified in 1925 after an aerial archaeology survey by Alexander Keiller and OGS Crawford. Crawford credits the discovery to an aerial photograph.

Most of the 168 post holes held wooden posts, although Cunnington found evidence that a pair of standing stones may have been placed between the second and third post hole rings. The positions of the postholes are currently marked with modern concrete posts which are a simple and informative method of displaying the site. Further comparisons with Stonehenge were quickly noticed by Cunnington; both have entrances oriented approximately on the midsummer sunrise.

Archimedes's steam cannon

A steam cannon is a cannon where projectiles are launched by steam. The first steam cannon was designed by Archimedes during the Siege of Syracuse. Leonardo da Vinci was also known to have designed one. The device is metal tube, which would be placed in a furnace: one end of the tube is closed and the other loaded with a projectile. Once the tube reached a high enough temperature, a small amount of water in injected in behind the projectile. Leonardo da Vinci guessed that the water would rapidly expand into vapour, blasting the projectile out the front of the barrel.

Why the name "Archimedes"? Let us remember what the 2nd century AD author Lucian wrote about.
"During the Siege of Syracuse (c.214–212 BC), Archimedes destroyed enemy ships with fire. Centuries later, Anthemius of Tralles mentions burning-glasses as Archimedes' weapon. The device, sometimes called the "Archimedes heat ray", was used to focus sunlight onto approaching ships, causing them to catch fire. This purported weapon has been the subject of ongoing debate about its credibility since the Renaissance. René Descartes rejected it as false, while modern researchers have attempted to recreate the effect using only the means that would have been available to Archimedes. It has been suggested that a large array of highly polished bronze or copper shields acting as mirrors could have been employed to focus sunlight onto a ship. This would have used the principle of the parabolic reflector in a manner similar to a solar furnace." More  wiki

Profiles - Chief Joseph

Chief Joseph (1840 – 1904) was the chief of the Wallowa band of Nez Perce during General Oliver O. Howard's attempt to forcibly remove his band and the other "non-treaty" Nez Perce to a reservation in Idaho. For his principled resistance to the removal, he became renowned as a humanitarian and peacemaker.

From Wiki

Joseph the Younger succeeded his father as chief in 1871. Before his death, the latter counseled his son:

"My son, my body is returning to my mother earth, and my spirit is going very soon to see the Great Spirit Chief. When I am gone, think of your country. You are the chief of these people. They look to you to guide them. Always remember that your father never sold his country. You must stop your ears whenever you are asked to sign a treaty selling your home. A few years more and white men will be all around you. They have their eyes on this land. My son, never forget my dying words. This country holds your father's body. Never sell the bones of your father and your mother." Chief Joseph commented "I clasped my father's hand and promised to do as he asked. A man who would not defend his father's grave is worse than a wild beast."

...

Chief Joseph formally surrendered to General Nelson Appleton Miles on October 5, 1877 in the Bear Paw Mountains of the Montana Territory, less than 40 miles south of Canada in a place close to the present-day Chinook in Blaine County. The battle is remembered in popular history by the words attributed to Chief Joseph at the formal surrender:
"Tell General Howard I know his heart. What he told me before, I have it in my heart. I am tired of fighting. Our chiefs are killed; Looking Glass is dead, Too-hul-hul-sote is dead. The old men are all dead. It is the young men who say yes or no. He who led on the young men is dead. It is cold, and we have no blankets; the little children are freezing to death. My people, some of them, have run away to the hills, and have no blankets, no food. No one knows where they are—perhaps freezing to death. I want to have time to look for my children, and see how many of them I can find. Maybe I shall find them among the dead. Hear me, my chiefs! I am tired; my heart is sick and sad. From where the sun now stands, I will fight no more forever."

Caligula's Tomb

Caligula's Floating Palaces

"Caligula was a man of many passions, and he indulged nearly all of them, including his passions for chariot racing, theatrical performances, gladiatorial games, and ships. During his brief rule from A.D. 37 to 41, he had two enormous ships--a sailing ship and an oared galley--built and anchored on Lake Nemi as pleasure craft. Pillaged and deliberately sunk later in the first century, they were recovered in a feat of engineering sponsored by Benito Mussolini in the 1930s, but destroyed during a German retreat in 1944."  http://www.archaeology.org/0205/abstracts/caligula.html

Here an interesting description, written by Colonel Maceroni, in 1838.

A very singular piece of antiquity exists in the lake of Nemi, of which I have never seen any mention made by travellers. On the north-east side of the lake, in about forty feet water, lie the ruins of a large floating palace constructed by the Emperor Claudius or by Nero (in fact, Caligula). The lakes of Albano and Nemi are the craters of extinct volcanos, from which, at the time when they were covered by the sea, has proceeded all that vast quantity of tuffo and puzzolana which covers the Campagna di Roma. The high, steep banks of these circular lakes, covered with most beautiful trees and villas, cause one side of the water below to be constantly sheltered from the wind. Hence a floating habitation will give the choice of shade and shelter, or sunshine as the season may require. The way in which I became acquainted with this sunken palace was quite accidental. Being one evening in my punt about to lay some eel lines, the fisherman whom I employed told me, that the best place in that vicinity was "about the old palace". I stared and looked about. "What palace?" said I. I see plenty of houses and cottages, and ruins, on the hills around, but they are not even quite at the water's edge. My man rejoined : "I mean about the wooden palace under water in which the Emperor Claudius used to live." Delighted and excited by this announcement more than I should have been by the capture of a thousand eels as big as the mast of a ship, I hastened to the spot, but the declining sun had sunk below the high crater wood-clothed margin of the lake, and looking down into the limpid waters, all seemed dark and blue, and nothing could be seen but the hills and trees, and my own anxious physiognomy reflected in the watery mirror. However, I laid my lines, the hooks being baited with the thighs of frogs, and next morning I found fourteen eels, all about a pound a piece, and some of three pounds weight. Moreover, a brilliant sunshine enabled me to see the sunken palace, which appeared to be about one hundred feet square and fifteen to twenty feet high. How did I then regret not having the command of a diving-bell! What most curious and precious objects of antiquity might not be found in the interior of this construction? But this discovery I must leave to some future traveller, who may have the means of causing a diving-bell to be constructed at Rome, and know how to use it. As for myself, I mentioned the discovery to General Miolis, the imperial locum tenens, or Governor of Rome, and also to the learned antiquary, Mr. Norviuse de Monbreton, but nothing was done.

Gandhara

Gandhāra is the name of an ancient kingdom in northern Pakistan and eastern Afghanistan. This Kingdom lasted from early 1st millennium BC to the 11th century AD. It attained its height from the 1st century to the 5th century under the Buddhist Kushan Kings. Gandhāra is known for the distinctive Gandhāra style of Buddhist art, which developed out of a merger of Greek, Syrian, Persian, and Indian artistic influence. This development began during the Parthian Period (50 BC – AD 75). Gandhāran style flourished and achieved its peak during the Kushan period, from the 1st to the 5th century. It declined and suffered destruction after invasion of the White Huns in the 5th century.
By the time Gandhara had been absorbed into the empire of Mahmud of Ghazni, around 1000 AD, Buddhist buildings were already in ruins and Gandhara art had been forgotten. In the 19th century, British soldiers and administrators started taking interest in the ancient history of the Indian Subcontinent. In the 1830s very old coins were discovered and decipherment of some  Chinese records provided locations of Buddhists shrines. Along with the discovery of coins, these records provided necessary clues to piece together the history of Gandhara. In 1848 Gandhara sculptures have been discovered north of Peshawar. From then on a large number of Buddhist statues have been discovered in the Peshawar valley.

Human, All Too Human - 4 - Lifespan

"A new study by a Washington University in St. Louis suggests life expectancy was probably the same for early modern and late archaic humans and did not factor in the extinction of Neanderthals. Our species, Homo sapiens, is the only surviving lineage of the genus Homo. Still, there once were many others, all of whom could also be called human. One puzzle was the lack of elderly individuals. It was therefore suggested that early hominins might have had a shorter life expectancy than early modern humans, with our lineage ultimately outnumbering Neanderthals, contributing to their demise." But  Neanderthals and early modern humans had same lifespan.

The 'millicrab'

"One of the most studied objects in the sky, the Crab Nebula is the remnant of an exploded star 6500 light-years away from Earth. At its core is a neutron star that spins 30 times per second, driving processes that are responsible for it X-ray and gamma-ray emissions. Until recently the X-ray intensity of the Crab was considered to be so stable that it is used as a "standard candle" to judge the relative brightness of other objects in the sky. Indeed, X-ray brightness is often expressed in units of "millicrab"." X-ray astronomers have for decades calibrated their detectors using the Crab Nebula, but now an international team of astronomers has discovered that the X-ray output of the Crab has dropped by 7% in the last two years.

"For a moment the Canterville ghost stood quite motionless in natural indignation; then, dashing the bottle violently upon the polished floor, he fled down the corridor, uttering hollow groans, and emitting a ghastly green light. Just, however, as he reached the top of the great oak staircase, a door was flung open, two little white-robed figures appeared, and a large pillow whizzed past his head! There was evidently no time to be lost, so, hastily adopting the Fourth Dimension of Space as a means of escape, he vanished through the wainscoting, and the house became quite quiet." Oscar Wilde, The Canterville Ghost, http://en.wikisource.org/wiki/The_Canterville_Ghost/Chapter_I
Curioso richiamo alla quarta dimensione.

Venus

A hemispheric view of Venus was created using more than a decade of radar investigations culminating in the 1990-1994 Magellan mission, and is centered on the planet's North Pole. The Magellan spacecraft imaged more than 98 percent of the planet Venus and a mosaic of the Magellan images (most with illumination from the west) forms the image base.
