La fisica degli attosecondi La parola chiave per capire meglio l’impresa dei laureati di oggi è attosecondi. Questa infatti è la scala temporale alla quale si muovono gli elettroni. Un attosecondo è un intervallo di tempo uguale a un miliardesimo di miliardesimo di secondo. In notazione scientifica si scrive così: 1 as = 10–18 s. Per intenderci, un battito cardiaco dura tanti attosecondi quanti sono i secondi passati dall’inizio dell’universo. I fisici hanno pensato a lungo che la scala degli attosecondi fosse inarrivabile per i nostri strumenti. Con i laser è possibile generare impulsi nell’ordine dei femtosecondi (un milionesimo di miliardesimo di secondo) che ci permettono di sondare i fenomeni atomici, ma non i velocissimi elettroni. Agostini, Krausz e L’Hullier hanno invece trovato il modo di infrangere questa barriera. Il loro lavoro ha quindi dato origine a un nuovo campo, la fisica degli attosecondi (o scienza degli attosecondi). Gli esperimenti Il primo passo lo ha compiuto Anne L'Huillier, la quinta donna della storia a ricevere il Nobel per la Fisica. Nel 1987 stava studiando con un laser un campione di gas nobile e misurò con uno spettrometro numerosi sovratoni, cioè onde luminose a lunghezza d’onda più corta (ultravioletta). In seguito scoprì che erano generati dagli elettroni che, dopo essere stati spostati dal laser, tornavano al loro posto emettendo luce. Agostini e Krausz usarono queste conoscenze per infrangere la barriera degli attosecondi. Infatti, i sovratoni generati dall’interazione tra laser e atomi potevano essere fatti interferire tra loro in modo tale da generare impulsi della brevità desiderata. Agostini riuscì a creare dei treni di impulsi di 250 attosecondi, mentre Krausz usò un’altra tecnica per generare un singolo impulso di 650 attosecondi. Heisemberg è salvo Anne L'Huillier è intervenuta alla conferenza stampa dell’annuncio specificando che queste tecniche non violano il principio di indeterminazione di Heisemberg, secondo cui non è possibile conoscere contemporanemente la posizione di una particella e la sua velocità. Aggiungendo che però oggi è possibile capire, per esempio, in quale parte di una molecola si trova un elettrone. Opuure quanto tempo impiega a migrarare da una regione a un’altra. La studiosa ha anche ricordato che è fondamentale continuare a finanziare queste ricerche. Molti stanno già pensando alle possibili applicazioni, ma è un lavoro che richiederà tempo.

La Isla de Pascua This 64-square mile island off Chile’s west coast goes by many names. Its English name is Easter Island, marking the day in 1722 when it was discovered by a European. In Spanish, it is called Isla de Pascua. The Rapa Nui, its first inhabitants, called it “The Navel of the World.” Experts do not agree on the history of Easter Island. It is unclear where the first people came from or when they arrived. Many people believe they came from neighboring Polynesia around AD 300. This culture built 900 enormous stone statues for which the island is famous. The statues are known as moai. Most of the moai are made of volcanic tuff. Tuff is a soft rock made from the ash that is forced out during a volcanic eruption. It is easier to carve than hard stones like marble, but it is not ideal for carving small details. The moai are considered megaliths (large stones that form prehistoric monuments). They stand up to 33 feet high when on their ceremonial platform (the average height is about 13 feet), and they weigh up to 82 tons. They usually have a trunk (body), inset arms, and an exaggerated head with angular edges. The head of each moai takes up about one-third of the total figure. It all shows that the people who created them could engineer monumental structures. Many moai stand with their backs to the sea. They watch the island like protective markers. Some low-relief carvings of religious deities were added to the backs of the moai at a later date. Experts are still trying to understand how they were carved and moved, and what they might mean. Chile took control of the island in 1888. At that time, its population was less than 200. The government used it for grazing livestock. Today, the mystery of Easter Island makes it a popular tourist spot. Valparaíso Valparaíso is a colorful blend of old and new traditions in Chile. This port city is an interesting example of daily life in Chile. Before the Panama Canal was opened in 1914, all ships traveling east to west had to pass all the way around South America. Valparaíso was ideally positioned as a stopping point in the Southern Pacific. Valparaíso has a long history of playing host to a large array of cultures and ideas. The city was known around the world as a place that embraced learning and new ideas. Pablo Neruda had a home in Valparaíso in the 1920s. After the Panama Canal was completed, shipping traffic declined significantly. Valparaíso was forgotten and fell upon hard times. In the 1990s, the government of Chile made an effort to revitalize the colorful port. Today it is a UNESCO (United Nations Educational, Scientific and Cultural Organization) World Heritage site. True to its history of embracing learning, it is also home to four universities. Tourists can visit the first stock exchange in Latin America. Valparaíso also has Chile’s first public library. Visitors stroll through cobblestone streets in the historic district. Here they can also view the city’s iconic colorful buildings. At night, music and street performers liven the experience.

Las Comidas Tradicionales To Chileans, nothing says home like pastel de choclo, a type of casserole made of beef and corn. The body of the casserole is flavorful. It contains beef, onions, raisins, and roasted chicken. It is topped off with a layer of creamed corn and then baked. Baking it brings out the sweetness in the corn, adding a contrast to the savory meat. The preferred type of corn is called choclo. This variety is grown in rugged conditions in the Andes. The kernels are large and hearty compared to other varieties. Another favorite dish in Chile is a type of meat stew called cazuela. Originally a native dish, it is now known as comfort food in Chile. Pork, beef, lamb, or chicken still on the bone is boiled in a traditional clay pot. To that, corn, potatoes, and other local vegetables are added. It is seasoned with onion and garlic. Pablo Rogat/Shutterstock When Chileans think about dessert, manjar is the first ingredient on their minds. It is a caramel sauce made from cooking milk, sugar, and vanilla. It is found in many desserts. It is used as filling in cakes, pies, and cookies. It is refrigerated to make puddings and custards. People even use it to sweeten their coffee.

Some Arctic Dinos Lived in Herds By Sid Perkins Just as interesting, however, is how this was discovered. Scientists didn’t look at a single fossil bone. Instead, they analyzed a large number of preserved footprints on a mountainside located toward the southern end of central Alaska. Anthony Fiorillo works at the Perot Museum of Nature and Science in Dallas, Texas. As a vertebrate paleontologist, he studies the fossils of creatures with backbones. In 2007, he was part of a research team exploring Denali National Park. “We rounded the corner and there they were,” he recalls. Thousands of footprints had been preserved in stone. “It was amazing.” Dinosaurs died out more than 65 million years ago (not counting birds, their modern-day relatives). So, it’s a bit surprising that scientists know so much about these ancient creatures. Now, a new study reveals that a certain type of duckbilled dinosaur lived in the Arctic year-round. These animals also traveled in herds that included many age groups, they find. The creatures even appear to have gone through a “teenage growth spurt.” Those tracks pepper a steep patch of exposed rock about twice as long as a football field and up to 60 meters (roughly 200 feet) wide. They sit at least 160 kilometers (100 miles) north of the Gulf of Alaska. Between 69 million and 72 million years ago, that now-rocky material was muddy sediment on a floodplain near a seacoast, Fiorillo explains. The hadrosaurs walked across the squishy mud. Later, the footprints they left turned to stone. Previous studies suggested adult duckbills took care of their young, says Fiorillo. The new evidence that these dinosaurs truly traveled in herds with multiple age groups confirms that parents cared for their young well beyond the time they left the nest, his team concludes. The researchers published their findings June 30 in Geology. © Science News for Students Thousands of tracks cover this rocky mountainside in Alaska’s Denali National Park. They provide a wealth of information about the size, age and lifestyle of certain dinosaurs. COURTESY OF PEROT MUSEUM OF NATURE AND SCIENCE EVIDENCE FOR HERDS O F DINOSAURS Small meat-eating dinosaurs called theropods had left behind a few of the tracks that Fiorillo’s team found in Denali. Birds had left some others. But the vast majority came from creatures called hadrosaurs. These large plant-eating duckbilled dinosaurs had been quite common during the Cretaceous Period. That helps explain one of their nicknames: “cattle of the Cretaceous.” For the new study, the researchers focused only on the hadrosaur tracks. More than half of the footprints were preserved so well that they had clear impressions of the skin on the dinosaurs’ feet. Most tracks had a similar level of preservation. That suggests all were probably left within a short period. Other fossils in the nearby rocks, including insect burrows, suggest these hadrosaurs had left their footprints during the summer. These are trace fossils — evidence of ancient life other than a preserved carcass or bone. At the time these dinosaurs lived, Fiorillio says, the average temperature in the warmest months was between 10° and 12° Celsius (50° and 54° Fahrenheit). That’s about what conditions are like today along the border between Canada and the lower 48 U.S. states, he notes. The team measured a large sample of the duckbills’ footprints. They fell into four distinct size ranges. The largest tracks, presumably made by adults, measured about 64 centimeters (25 inches) across. The smallest tracks, 8 centimeters (3 inches) wide, were likely left by young duckbills. They would have been no more than a year old. Tracks of two other size groups were probably made by juveniles and near-adults. These data suggest the community of hadrosaurs included four different age groups. © Science News for Students A hadrosaur footprint made roughly 70 million years ago. For scale, the long blue bar at right is 10 centimeters long; each small blue or white bar measures 1 centimeter. COURTESY OF PEROT MUSEUM OF NATURE AND SCIENCE © Science News for Students THESE DINOSAURS DIDN’T MIGRATE About 84 percent of the tracks sampled for the new study had been left by older hadrosaurs — adults or near-adults. Roughly 13 percent came from the youngest members of the herd. And a mere 3 percent came from herd members considered to be juveniles, says Fiorillo. The rarity of tracks by these tweens suggests that the young of this species had a rapid growth spurt. If true, they would have spent relatively little time at this vulnerable size — and therefore left very few tracks. “What’s really neat is how many small tracks there are,” notes Anthony Martin. An ichnologist — or expert in trace fossils — he works at Emory University in Atlanta, Ga. Other scientists had analyzed fossil bones from duckbills. These studies had hinted that the equivalent of adolescent hadrosaurs would have experienced growth spurts. But the new findings are “the best evidence that I’ve seen,” says Eric Snively. He’s a vertebrate paleontologist at the University of Wisconsin- La Crosse. “This is a great study,” he adds, “and further evidence that juvenile hadrosaurs grew up in an eye-blink.” Also previously, researchers had proposed that Arctic dinosaurs migrated farther south for the winter. That’s because even if the region was much warmer than it is today, nights in the high Arctic would have been 24 hours long. So, with no sunshine for several months, Alaska would have had long periods of very bleak, chilly weather. But finding juveniles in the herd strongly suggests that these dinosaurs remained in the Arctic all year. That’s because adolescents and preadolescents wouldn’t have had the strength or stamina to make those long treks, Fiorillo maintains. Field work is often harsh. Paleontologists studying the dinosaur footprints here on an Alaskan mountainside sometimes worked in cold and fog. COURTESY OF PEROT MUSEUM OF NATURE AND SCIENCE © Science News for Students The presence of very young dinosaurs might have been expected, he notes: If this were a nesting region, the babies would have hatched sometime just before summer. And remember, that’s when these tracks were left. But that wouldn’t explain the juveniles, he says. The team’s findings “suggest that these dinosaurs were overwintering in Alaska somehow,” says Snively. At the time, the average temperature in the region remained above freezing even during the winter, he notes. But, he adds, “this study raises interesting issues about how the dinosaurs could live in the region when it was pretty dark for several months at a time.”

SS Spanish Version 8/25/25 Topic: Fall of Rome, Medieval Europe, and the Role of Monasteries Tema: La caída de Roma, la Europa medieval y el papel de los monasterios Reading Passage / Pasaje de Lectura The Roman Empire, once the most powerful civilization in the world, began to weaken during the 4th and 5th centuries. Several causes contributed to its decline, including political corruption, heavy taxes, reliance on slave labor, and invasions by barbarian tribes such as the Visigoths and Vandals. In 476 CE, the last Roman emperor in the West was removed, marking the official fall of the Western Roman Empire. This event brought significant changes to Europe, as centralized government disappeared and smaller kingdoms took control. El Imperio Romano, una vez la civilización más poderosa del mundo, comenzó a debilitarse durante los siglos IV y V. Varias causas contribuyeron a su declive, incluyendo la corrupción política, los altos impuestos, la dependencia de la mano de obra esclava y las invasiones de tribus bárbaras como los visigodos y los vándalos. En el año 476 d.C., el último emperador romano en Occidente fue depuesto, marcando la caída oficial del Imperio Romano Occidental. Este evento trajo cambios significativos a Europa, ya que el gobierno centralizado desapareció y reinos más pequeños tomaron el control. After the fall of Rome, Europe entered the Middle Ages, also known as Medieval Europe. This period lasted roughly from 500 to 1500 CE. Life during this time was shaped by the feudal system, where kings gave land to nobles in exchange for loyalty and military service. Most people were peasants who farmed the land and gave a portion of their harvest to their lords. Castles provided protection, while the Catholic Church became the most powerful institution, guiding people’s beliefs and daily lives. Después de la caída de Roma, Europa entró en la Edad Media, también conocida como la Europa medieval. Este período duró aproximadamente del año 500 al 1500 d.C. La vida durante este tiempo estaba organizada por el sistema feudal, en el cual los reyes daban tierras a los nobles a cambio de lealtad y servicio militar. La mayoría de las personas eran campesinos que cultivaban la tierra y entregaban una parte de su cosecha a sus señores. Los castillos brindaban protección, mientras que la Iglesia Católica se convirtió en la institución más poderosa, guiando las creencias y la vida diaria de las personas. In the uncertain times of Medieval Europe, monasteries served as centers of learning and stability. Monks lived simple lives dedicated to prayer, work, and study. They carefully copied ancient texts, preserving knowledge from Greece and Rome. Monasteries also offered medical care, shelter to travelers, and food to the poor. In many ways, they became islands of peace and knowledge in a world often filled with war and hardship. En los tiempos inciertos de la Europa medieval, los monasterios sirvieron como centros de aprendizaje y estabilidad. Los monjes vivían vidas simples dedicadas a la oración, el trabajo y el estudio. Ellos copiaban cuidadosamente textos antiguos, preservando el conocimiento de Grecia y Roma. Los monasterios también ofrecían atención médica, refugio a viajeros y comida a los pobres. De muchas maneras, se convirtieron en islas de paz y conocimiento en un mundo a menudo lleno de guerras y dificultades.

Era uma vez um camponês que foi à floresta apanhar um pássaro para mantê-lo cativo em sua casa. Conseguiu capturar uma águia recém-nascida e, embora fosse a rainha de todos os pássaros, pô-la no galinheiro a comer milho e ração de galinhas. Passados cinco anos, este homem recebeu a visita de um naturalista que, ao passar junto do gali- nheiro, exclamou: - Aquele pássaro não é uma galinha! É uma águia! - De facto - disse o camponês. É uma águia mas eu criei-a como galinha. Por isso, apesar das asas de quase três metros, já não é uma águia. Transformou-se em galinha como as outras. - Não! - retorquiu o naturalista. Ela é e será sempre uma águia. Tem um coração de águia que a fará voar às alturas. - Não, não! - insistiu o camponês. Ela transformou-se em galinha e nunca voará. Então o naturalista pegou na águia, ergue-a bem alto e, desafiando-a, disse: - Tu és uma águia. Já que pertences ao céu e não à terra, abre as asas e voa! Mas a águia pousou sobre o braço estendido do naturalista. E, ao ver as galinhas no chão a comer grãos, pulou para junto delas. O camponês comentou: - Eu disse-lhe que ela é uma simples galinha! - Não - insistiu o naturalista. Ela é uma águia. E uma águia será sempre uma águia. Vamos experimentar novamente amanhã. No dia seguinte, o naturalista subiu ao telhado da casa com a águia e sussurrou-lhe: - Águia, tu és uma águia! Abre as asas e voa! Mas a águia tornou a pular para o chão. O camponês sorriu e voltou à carga: - Já lhe disse que agora ela é uma galinha! - Não - respondeu firmemente o naturalista. Ela é águia e há de voar. No dia seguinte, o naturalista e o camponês pegaram na águia e levaram-na para fora da cidade, longe das casas, no alto de uma montanha. O naturalista ergueu a águia para o alto e ordenou-lhe: - Tu és uma águia, pertences ao céu e não à terra, abre as tuas asas e voa! A águia olhou ao redor. Tremia como se experimentasse uma nova vida. Mas não voou. Então o natu- ralista segurou-a firmemente, bem na direção do sol, para que os seus olhos pudessem encher-se da claridade solar e da vastidão do horizonte. Nesse momento, ela abriu as suas potentes asas, grasnou o típico kau-kau das águias, ergueu-se, soberana, sobre si mesma e começou a voar, a voar para o alto, a voar cada vez mais alto. Voou... voou.., até se confundir com o azul do firmamento..
