1 . No one is sure how the ancient Egyptians built the pyramids near Cairo. But a new study suggests they used a little rock ‘n’ roll. Long-ago builders could have attached wooden poles to the stones and rolled them across the sand, the scientists say.
“Technically, I think what they're proposing is possible,” physicist Daniel Bonn said.
People have long puzzled over how the Egyptians moved such huge rocks. And there's no obvious answer. On average, each of the two million big stones weighed about as much as a large pickup truck. The Egyptians somehow moved the stone blocks to the pyramid site from about one kilometer away.
The most popular view is that Egyptian workers slid the blocks along smooth paths. Many scientists suspect workers first would have put the blocks on sleds(滑板). Then they would have dragged them along paths. To make the work easier, workers may have lubricated the paths either with wet clay or with the fat from cattle. Bonn has now tested this idea by building small sleds and dragging heavy objects over sand. .
Evidence from the sand supports this idea. Researchers found small amounts of fat, as well as a large amount of stone and the remains of paths.
However, physicist Joseph West, who led the new study, thinks there might have been a simpler way. West said, “I was inspired while watching a television program showing how sleds might have helped with pyramid construction. I thought, ‘Why don't they just try rolling the things?’” A square could be turned into a rough sort of wheel by attaching wooden poles to its sides, he realized. That, he noted, should make a block of stone “a lot easier to roll than a square”.
So he tried it. He and his students tied some poles to each of four sides of a 30-kilogram stone block. That action turned the block into somewhat a wheel. Then they placed the block on the ground.
They wrapped one end of a rope around the block and pulled. The researchers found they could easily roll the block along different kinds of paths. They calculated that rolling the block required about as much force as moving it along a slippery(滑的) path.
West hasn't tested his idea on larger blocks, but he thinks rolling has clear advantages over sliding. At least, workers wouldn't have needed to carry cattle fat or water to smooth the paths.

2 . The discovery of Liangzhu Culture
From December 1936 to March 1937, three archaeological diggings were carried out in the suburbs of Hangzhou,where loads of black ceramics and stoneware were brought to light.
Inspired by these relics, an archaeology lover named Shí Xingeng, who came from West Lake Museum in Hangzhou, wrote several detailed reports on the digging. However, he had to put his work aside when China started to fall into Japan's military aggression. Shi joined the resistance movement against Japanese invasion and died of disease in 1939. What passed away along with him during the war were many of Liangzhu's precious relics.
Fortunately, Shi's reports were finally published in Shanghai in 1938, which caught considerable attention of archaeological circles, In 1959,the name Liangzhu Culture was given to the independent regional culture by archaeologist Xia Nai. It represented an earlier civilization that had remained unknown to historians. The culture, as the radiocarbon dating applied to the relics proved, existed between 3,300 and 2,200 B.C.
It is commonly believed that the earliest known Chinese written language dates back to more than 3,000 year ago; when oracle bone script appeared in Shang Dynasty. But Liangzhu Culture might provide evidence of a written language that appeared in China at least 1,000 years ealiler.
In 2007, Liangzhu Ancient City was reported to be discovered in Hangzhou, where archaeological diggings revealed a large and early walled city in Chinese history. There were man-made hills and streams in the city area, which were very likely part of the early designed urban landscape. To protect the urban space which was formed by waterways and entrances both Inside and outside the city, a flood control system was connected to the river networks and 11 dams. In the fields outside the wall, archaeologists discovered rains of the residences, tombs, workshops, and docks with wooden boats.

A search of the surrounding area revealed no evidence of a Hittite settlement dating back to the time of the statues. Also, the steep size of the sculptures meant that the sculptors likely did not intend to move them very far.
Summers assumes that, rather than being meant for a palace or a great city, the lions were being created for a monument to mark something else- water
“I think it's highly likely that that monument was going to be associated with one of the very abundant springs that are quite close,” he said in the interview, ”There are good parallels (平行线) for association of Hittite sculptural traditions with water sources”
Indeed one well-known monument site, known as Eflatun Pnar, holds a sacred pool that "is fed by a spring beneath the pool itself,” write Yiit Erbil and Alice Mouton in an article that was published in the most recent edition of the Journal of Near Eastern Studies. The two researchers were writing about water religions in ancient Anatolia (Turkey).
"According to the Hittite cuneiform(楔形文字)texts, water was seen as an effective purifying element,” Erbil and Mouton write, "used in the form of cleaning or even full baths during ritual performances, its cleaning power is self-evident."
To the Hittites the natural world, springs included, was a place of great religious importance, one worthy of monuments with giant lions. "These things (water sources) were sacred, just as their mountains were sacred,” Summers said.

The time capsule was buried in Aspen .Colorado .in 1983, shortly after Jobs attended the International Design Conference being held in that city. Organizers called the device the Aspen Time Tube and contributed items like Rubik's cubes(魔方) and some iconic music. Jobs added his own items to the capsule ,including the " Lisa" ( also known as an "Apple" )"mouse he used for his presentation at the conference. '
Younger readers may not recognize the name but the Lisa Apple mouse was one of the first commercial mice released to consumers. The mouse was specially designed for the Apple Lisa computer. It's also the first personal computer to offer users a graphical user interface(图形用户界面)
Initially ,the plan was to dig up the time capsule in the year2000,but organizers forgot its exact location. Recently .they brought in researchers working with the National Geographic Channel show Diggers to find the device. Eventually they came across the 13-foot-long.1. 5-foot-diameter tube. inside they found a lot of 1980s artifacts(人工制品）that are still being catalogued.
“When the end came off .literally things just poured out .”noted Diggers host Tim Saylor "There must be literally thousands of things in there.”
“They had the foresight to put a bunch of stuff in plastic bags." Saylor said .“I could see at least a dozen plastic bags and other items. But I know for sure there got to be photographs in there. People had hand-written things on the back of the photographs ,so there will be some really interesting things inside.”
Among the artifacts researchers expect to discover inside :a Steve Jobs speech in which the Apple visionary outlines his predictions for future technologies. We should know more about the researchers ,discoveries once the Diggers program airs this fall.
