Archeologists discover oldest plant fiber
Archeologists from Harvard University and the National Museum of Georgia-based institutions have discovered linen fiber from 34,000 years ago, which may be the oldest plant fiber ever used by humans. These wild linen fibers were discovered by archaeologists in Georgia.They began excavation work in 1996. They found these fibers when they studied the samples with a microscope and determined their age using radioactive carbon. Some of these fibers had traces of weaving, while others were dyed black, gray, pink, and so on. The oldest plant fiber discovered in the archaeological community was unearthed in the territory of the Soviet Republic, 28,000 years ago. Read more exciting novels for free
Archeologists discover prehistoric giant turtle
Archeologists have discovered many types of prehistoric super turtles. In 1895, George Reber Wielan discovered a giant fossil of the ancient turtle, Archelon, by the Cheyenne River in Caster County, South Dakota. In 1898, a second fossil containing a skull was found in the same area. A third was found in 1902, a fourth in 1992, and a fifth in 2002. The largest ancient turtle fossil, Brigita, was 4.6 meters long, 4 meters wide between its flippers, and weighed 2.2 tons. In the 1970s, paleoniologists discovered a sea turtle in Argentina. The turtle shell fossil of Stupendemys geomaculus was 2.35 meters long. A turtle shell fossil, numbered UEPM-CIAPP-2009, was also found. Although it was incomplete, it was estimated that the complete length could reach 3.3 meters. According to the shell fossil with a maximum length of 3.3 meters, it was estimated that the length could reach 5 meters (because the neck was also very long) and weighed about 5 tons. New fossil discoveries showed that some individuals had carapaces up to three meters long and weighed an estimated 1145 kilograms. The male tortoises of this species have horns on the back of their shells, which may be used to fight with other males or defend against natural enemies. Their food is mainly fish or other aquatic organisms. In 1895, paleologists discovered a huge skeleton from the late cretaceous period. Two years later, they found the missing head. After assembling it, they restored the largest turtle in the history of Earth, Archelon ischiros. Its head to tail was 4.6 meters long, and its width was 4 meters. It was estimated that it weighed more than 3 tons when it was alive. In South America, a giant freshwater turtle the size of a sofa was found that had coexisted with humans 10,000 years ago. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Archeologists discover ancient Egyptian ships
Archeologists have found a variety of evidence related to ancient Egyptian ships. From ancient documents, tomb paintings, embossed, models, and ship wrecks, one could find evidence of the existence of various ships in ancient Egypt. Five intact wooden boats were found, and they belonged to different types. Only two of the fragments were related to the boats or yachts at the funeral ceremony. The ship's wood excavated from a Pharaoh's port in the Red Sea provided direct evidence of Egypt's special ship construction model. In addition, archaeologists have excavated thousands of representative models of ships and ships, which can be traced back to the Neoliths. From the earliest days, Egyptian society had clearly relied on ships and sea travel. Although there was little direct evidence of navigation, indirect evidence such as the second-phase pottery of the Negada culture found on the coast of Israel, the fragments of stone bottles printed with the names of the rulers of the Second Dynasty, and even the golden axe of Egypt engraved with the symbol of the Fourth Dynasty found in Lebanon. These indirect evidence pointed to the existence of maritime communication between ancient Egypt and other regions. In addition, a 43.5-meter-long cedar hull that was reassembled next to the Great Pyramid of Giza also provided relevant evidence for the study of ancient Egyptian ships. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Archeologists discover 800-year-old cell phone
According to reports, Austrian archaeologists have discovered an 800-year-old mobile phone, but it is a man-made clay model of a mobile phone with cuneiform text on the buttons. Due to the lack of detailed excavation details and the fact that it was too similar to the Nobel phone, many people thought that it was an elaborate hoax, but there were still conspiracy theories who claimed that it was evidence of aliens visiting Earth or proof of the existence of time travel. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Is the plant fiber fragrant cloud yarn man-made?
The fragrant cloud muslin was not man-made. Fragrant cloud yarn was the only real silk fabric in the world that was dyed with pure plant dye. Its raw material was natural plant fiber. The production process used traditional craftsmanship, such as applying the juice of yam on the silk and drying it repeatedly. Then, the river mud rich in minerals such as iron ions was applied to the surface of the silk for reaction. It was a kind of silk fabric produced in Guangdong, China.

He could also be seen as a character related to archaeology. - In novels with archaeology as the background, there may be people like folk archaeologists who are similar to archaeologists, such as the folk archaeologists in "Listening to Leaks", who show their skills around the archaeological research of "Nine Tripods and Seven Gui". <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
Archeologists excavate Aegean island
An international team of archaeologists led by experts from the University of Thessalia in Greece carried out an archaeological excavation on the island of Friokastraki in the Aegean Sea. The island was small and rocky, located near Sisnos Island. For more than 1500 years, there was a city on the island that was once ruled by pirates in ancient times. The archaeological excavation work lasted for many years. In the past year, many important cultural relics were discovered in the field excavation, such as stones engraved with ancient inscriptions. These inscriptions provided powerful evidence for exploring the history of human habitation on the island. By deciphering the contents of the text, it was determined that humans had lived on the island from the 12th century B.C. to the 7th century A.D. The archaeologists also found evidence of an ancient bureaucracy on the island, such as building rules and penalties for violating the rules carved into stone, as well as inscriptions of honorary titles (though names were rubbed out) awarded to residents by local authorities. At the same time, many ancient inscriptions were destroyed, and archaeologists believe that during the Byzantine period, stone slabs with ancient inscriptions might have been used as building materials. An ancient sanctuary, an early Byzantine shrine, and the ruins of a church were also found on the island. Well-preserved pottery, jewelry, and female statues were found in the sanctuary. In addition, marble bases of ancient statues were also found, which were repeatedly used as one of the basic elements of Byzantine's early fortifications. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

carbon fiber racket
The carbon fiber racket was made of carbon fiber woven composite materials. In the 1970s, Japan began to use carbon fiber materials in the racket, and then the United States began to use carbon fiber composite materials for racket manufacturing, opening the first use of carbon fiber composite materials in the racket industry. The carbon fiber racket had many advantages over the traditional material racket, such as its low density, high specific strength and specific module, higher fatigue resistance, higher design freedom, and good shock absorption. It could help athletes improve stability, reduce vibration, and make the ball more stable. In terms of production technology, the production process required high temperature and high pressure to allow the carbon fiber and the resin to interact to form a complete racket. There were differences in production processes and materials between mass-produced rackets and rackets for professional players. The rackets for professional players cooled slowly before opening the mold, which took a long time and increased the cost. The carbon fiber and resin used were of better quality, more stable and consistent, and the price was higher. Different types of rackets (for example, professional rackets and amateur rackets) differed in many ways: 1. ** Model **: Professional players are used to using racket models from the early stages of their career. Muscle memory makes them rarely change them. The sponsors keep the early models to produce the racket for them. For amateurs, it is more difficult to get the same racket as professional players, and the racket performance has changed in the past 20 years. 2. ** In terms of parameters and accuracy **: Professional players 'rackets have huge differences in parameters, such as length, weight, pounds, etc., which may reach higher or lower values, and there are also differences in accuracy. They will also make custom-made modifications to the racket, such as adding weight, changing the length of the handle, changing the drilling of the string bed, etc. There is a certain quality error in amateur rackets. At present, the better brands can guarantee a margin of error of 5 - 7g. 3. ** Handle **: Professional players can customize the shape of the racket handle according to their needs. The inner handle leather is mostly made of calfskin, which has the advantages of durability, stable performance, and sharp edges. However, some players use artificial inner handle leather. Amateur rackets rarely have such custom-made handles. 4. ** String **: Most professional players use catgut + pet fiber, which is more expensive. Some players use string brands such as Babolat's rpmblast. Amateurs can choose according to their own situation. In comparison to the carbon racket, the carbon fiber racket was sturdier and more elastic. The carbon material was an unprocessed material. The carbon fiber was made from carbon fiber and then woven into a net to make the racket. After weaving, the carbon fiber was more flexible. Nowadays, the mainstream racket was made of carbon fiber. Blockade rackets that cost more than 200 yuan were basically made of carbon fiber, but there were differences in whether other materials were added, as well as the performance of the materials and the adjustment. Some high-end brands, such as Yonex, added other materials (such as tungsten) to the carbon fiber weaving to significantly improve the performance of the racket. Li Ning and Shengli also had similar practices. While watching the Olympics, you can also read the wonderful novels related to the Olympics!
Archeologists spend their lives dealing with fossils
An archaeologist was an expert in the study of ancient buildings, tombs, tools, and other objects. Their main purpose was to place the material remains in a historical context to increase understanding of the past. Fossil was the remains, relics, and activity traces of ancient creatures preserved in rock formations, as well as the organic residue after the decomposition of organisms. It provided extremely important evidence for studying the history of biological evolution and determining the age of the stratum. Although fossils were one of the important objects of archaeologists 'research, the scope of archaeologists' research was not limited to fossils. They also studied ancient buildings, tools, and other cultural relics. Therefore, it could not be said that archaeologists dealt with fossils all their lives. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
