The Portuguese navigator Bartolomeu Dias first crossed here in 1488. He named it “Storm Cape”. Later, the king of Portugal changed its name to “Nose of Good Hope”. The entire southern part of the Cape peninsula is a national park that is wild, rolling hills, beautiful scenery and has not been ravaged by human hands. The Cape of Good Hope has been considered a place that hasn’t changed much in the last 500 years, since the Portuguese explorer Bartolomeo Dias discovered it. The route around Cape Hope is important, but the waters next to it are still a known danger in the world. South of Cape Hope is an area with strong westerly winds, on the immense sea surface there is nothing to cover, so the waves are big Before the Suez Canal was built in 1869, the Cape of Good Hope was the only sea route between Europe and Asia. A lighthouse is built on top of a mountain 249 meters above sea level. However, it is often covered by clouds, so it has been decommissioned since 1911, after a shipwreck accident. This place is only open to tourists to enjoy the view. Another lighthouse was built as a replacement, just over 80 meters above sea level. Coming here, visitors’ emotions surged: the greatness, generosity, romance of nature; the gentleness, the blue, the charm of the sea; boundless love, hope, human creative labor. Cape of Good Hope is the most beautiful destination, not to be missed when coming to South Africa.

The scene of the launch of the Truong Chinh – 5B missile in Hainan on April 29 (Photo: Tan Hoa commune). According to the Hong Kong news site the East On May 9, China’s Office of Construction to put people into space on Sunday morning said that fragments of the end-propeller compartment of the Truong Chinh – 5B (CZ-5B) rocket launched by China from the Van Xuong launch site, Hainan will return to the atmosphere at 9:12 am on the same day (Hanoi time); the area in which it re-entered the atmosphere lies above 28.38 ° east longitude and 34.43 ° north latitude, in the Mediterranean sky. The European Union’s Center for Space Monitoring and Monitoring (EUSST) had previously predicted that the rest of the missile bay would return to the atmosphere at 2:32 a.m. GMT on Sunday (9:32 a.m. Internal on Sunday), with an error of adding or subtracting 139 minutes. According to EUSST, the probability of a missile fragment falling in densely populated areas is very low, but it can still happen uncertain due to the object’s uncontrolled. Thien Ha module of 100m3 capacity was launched by missile into space. American company Aerospace Corporation again stated that missile fragments will fall to the ground at 3:30 am UTC on Sunday (ie 10:30 am Hanoi time) with an error of plus or minus 4 o’clock. Actual drop times may vary. The Truong Chinh – 5B missile was launched into space by China on April 29 to bring the 100m3 Thien Hoa core module into orbit, this part will be the place for 3 astronauts to live and live on the Air Station. the Chinese Heavenly Palace. The launch of the core module is the first of the 11 missions required to complete the installation of a space station. The carrier was successfully put into orbit, but the rocket’s propulsion chamber lost control and fell back to Earth. According to the Ministry of Foreign Affairs of China, the fragment of the missile will catch fire when it enters the atmosphere, so the potential for harm is extremely low. The missile falls down (all brown parts and 2 support chambers) with the trajectory of the debris moving around Trac Dat. Black dot is the falling point predicted by Aerospace on May 8 (Image: UDN). However, there has been controversy surrounding the rocket’s falling back to Earth. The US Army Space Command said on May 4 that they “are closely monitoring and reporting to the public the location of the missile debris. It is currently impossible to determine where it fell to Earth. Asked during a press conference on May 6 whether the US shot down fragments of Chinese missiles, US Defense Secretary Lloyd Austin said: “We expect it to fall where it will not cause it. casualties; hope it will fall into the ocean or the like “and said the US” has no plans to shoot it down “. During a press conference at the White House on May 5, when asked: “If the Chinese missile fragments cause harm to the US, will the US claim compensation,” White House spokesman Jen Psaki said: “No. it’s time to discuss this. We are tracking its position through Space Command and hopefully not in the end. ” “The US pays attention to solving the problem of space junk caused by increased activities in space,” she emphasized. The US hopes to cooperate with the international community to promote responsible behavior in the space. Photo of debris caught fire while crossing Italy on the night of May 8 (Photo: virtualtelescope.eu). Meanwhile, the Chinese side accused the Western media of overstating the fact that their missiles “lost control” and could cause great damage. According to the Reuters , sheet Global Times China’s claim that reports of the missile “out of control” and can cause damage are just “Western hype”. The Chinese Ministry of Foreign Affairs believes that the probability of harm caused by this process is extremely low. Mr. Uong Van Ban, spokesperson for China’s Ministry of Foreign Affairs on May 7, when answering questions from reporters during a regular press conference, said that international practice allows rockets to enter the atmosphere to throw and destroy. He said: “As far as I know, this missile applies a special engineering design, most of the parts will be worn out and destroyed during the return, potentially harmful to cargo operations,” he said. zero and above ground is extremely low; The relevant authorities will promptly notify the outside situation ”. The Chinese rocket propulsion chamber fell down before (Image: weibo). The Chinese side is very interested in monitoring the reintegration of the missile debris atmosphere, but declined to answer questions about where it was expected to fall, said Uong Van Ban; instead, he advised reporters to “consult the relevant agencies”. However, the National Aerospace Bureau of China did not respond to relevant questions from reporters Bloomberg . Since the US Skylab space station was out of orbit and crashed into Western Australia in 1979, most space programs have tried to avoid sending large missiles into orbit, because in this case Their return to Earth will be difficult to predict. According to the news of The Guardi This uncontrolled China Changzheng-2B missile compartment is 30 meters long, 5 meters wide and weighs 21 tons, it could become one of the largest space debris falling to the ground. Photo of Truong Chinh – 5B rocket propulsion compartment falling on May 6 (Photo: virtualtelescope.eu) This missile compartment is currently freely acrobatic around Earth, is about to enter the lower atmosphere, and is expected to fall uncontrollably down to Earth. Its orbital tilt is 41.5 degrees, meaning that areas of the Earth in the range from the north like Chicago, New York, Rome, Beijing, Hanoi and south to New Zealand, Chile are all on the Road moves and may fall. Although scientists expect that most of the debris will be burned and destroyed as it enters the atmosphere, there are still some that will fall to different places on earth, these parts include a metal and glass numbers have not been burned. Some scientists believe that it is irresponsible for China to let the missile debris return to Earth uncontrollably. “They (China) are responsible,” said Paulo Lozano, director of the Space Thrust Laboratory at the Massachusetts Institute of Technology (MIT). They either did not provide enough information or did enough work during the design process to prevent the space object from returning uncontrollably back to Earth. I think that’s very important …. Hope they won’t fall on land, especially in public places, the consequences will be very bad. ” Lozano said that almost all missile launches in the US require a second stage. During this phase, the engine will restart to bring the missile back to earth in an area that does not have any. designated person. However, the Truong Chinh – 5B missile does not have this design. According to Jonathan Black, director of the Maritime and Aviation Systems Laboratory at Virginia Tech, the technology has been in use for the past ten years. Although the Truong Chinh – 2B missile was just launched in late April, its technology is still decades ago. Scientists speculate that the high cost may be the reason China is not adopting new technologies. The propellant compartment of the Chinese missile fell to Guangxi province before (Image: weibo). Harvard astrophysicist Jonathan McDowell criticizes China for being negligent in this regard, not letting objects heavier than 10 tons fall to Earth from space. He said potentially dangerous debris may not be completely burned when returned to the atmosphere at supersonic speeds, but the probability of falling into the sea is higher because 70% of the earth’s surface is covered by Ocean. However, Mr. McDowell told Reuters that it was still possible that missile debris could fall on the ground; can even fall in densely populated areas, like fragments of another Truong Chinh-5B rocket that crashed on Côte d’Ivoire (Ivory Coast) in May 2020, destroying many buildings, But luck did not cause any casualties. Follow the latest information from the page the East at 11:33 a.m.: The China Space Construction Office announced: fragments of the last compartment of the missile carrying Truong Chinh -5B returned to the atmosphere at 10:24 am. The fall zone was located at 72.47 ° east longitude and 2.65 ° north latitude over the Indian Ocean near the Maldives, most of the equipment was burned down during the reintegration of the atmosphere.

Space Station Skylab was launched by the US Aerospace Agency (NASA) in 1973. The agency had planned Skylab to operate for at least 10 years, but that did not happen. The sun radiates more energy than expected, increasing Skylab’s pull back to Earth. Image: NASA . On the night of July 11, 1979, Skylab returned to Earth and exploded over the Indian Ocean, west of Australia. Debris from the 85-ton space station is scattered across fields and small towns. Although no one was injured, the town of Esperance (Australia) fined $ 400 to NASA for littering. However, this agency does not pay. Until 2009, a new radio station in California (USA) paid this fine. Photo: State Library of Western Australia. Not only Skylab, there have been many instances where objects from space fell uncontrollably down to Earth. November 10, 2013, satellite GOCE The European Space Agency (ESA) caught fire and plunged into the Atlantic due to running out of fuel a month ago. According to the Space , GOCE is used to map the Earth’s gravity. Previously, scientists were concerned that the 1-ton satellite could fall to the mainland. Image: Space . Atmospheric Research Satellites (UARS) was launched by NASA in September 1991 with space shuttle Discovery to analyze the Earth’s ozone layer. In December 2005, a satellite weighing 6.5 tons, worth $ 750 million, was stopped by NASA before it fell to Earth in September 2011. While most of the satellites were burned, the remaining 532 kg of UARS fell to Canada, Africa, parts of the Pacific, Atlantic and Indian oceans. Image: NASA . NASA launches satellites Pegasus 2 weighed 11.6 tons in 1965 to study asteroids orbiting the Earth. The data was sent back to NASA by Pegasus 2 for about 3 years, then kept on orbit for 11 years. On November 3, 1979, the satellite returned to Earth and then exploded, debris plunging down the middle of the Atlantic Ocean. Image: NASA . Operated for 9 years from 1971 to 1982, Salyut 7 is the last space station in the Salyut program of the Soviet Union. On February 7, 1991, the 22-ton space station lost control, crashing to Earth after a period of time out of orbit while still connected to the Cosmos 1686 spacecraft. Both burned and exploded in the sky. Argentina, some fragments found in Capitan Bermudez region, no human casualties have been reported. Image: Space Age . On February 1, 2003, space shuttle Columbia exploded in the sky above Texas (USA) when returning to Earth, killing 7 astronauts. Investigations revealed that 82 seconds after the 100-ton ship took off, an insulating foam fell onto the carbon fiber board, puncturing the hull and damaging the body temperature protection while it was in service. speed 28,968 km / h. Although no one on the ground was injured, the Columbia event marked the second deadliest disaster in NASA’s space shuttle program. Image: NASA . Cosmos 954 , the secret satellite of the Soviet Navy used to spy on US nuclear submarines, launched on September 18, 1977 lost control. On January 24, 1978, a 3.8-ton satellite crashed northwestern Canada, causing radioactive debris to scatter over a large area. The Government of Canada asked the Soviet Union to pay $ 6 million for the search and cleanup campaign, but this country only accepted to pay $ 3 million. Image: NASA . On July 27, 2016, a boosters Long March 7 (Truong Chinh 7) China’s free fall, exploding in the American western skies. The image of a missile-generated light trail in the sky is widely shared on the Internet. The Long March missile chain is part of China’s plan to build an outer space station. Image: Matt Holt . Space Station Tiangong 1 (Heavenly Palace 1) China exploded over the southern Pacific on April 1, 2018. The 8-ton space station was launched in 2011, receiving 2 crew from 2012-2013 before completing the mission. In March 2016, China lost contact with Tiangong 1, allowing the space station to fall freely due to the gravity of the Earth. Image: CMSA .

In human society, we give and exchange what we need to maintain life is an indispensable daily activity of each individual. More than that, from the perspective of the entire human race, commercial exchanges have become such an indispensable part of today’s world, so much so that each person forgets to depend on them so much that Come on. Just take a minute looking around the room you are sitting in, or look through the top of your desk and ask yourself how much of it is made by you yourself, and you have the answer. word. How commercial activities have an impact on the history of human society is summarized in the book: Trade history – How trade shaped the world ? (Original name : A splendid exchange: How trade shaped the world ) by William J. Bernstein. He is a neuroscientist, an expert in financial and investment theory, and also a researcher in economic history. The book focuses on two main contents: the first is the formation and development of commercial activities; The second is the impact of trade on the shaping of human society throughout history as well as the world today. WJBernstein recounts commercial history from the earliest steps, when people came up with the idea of ​​genius and it was also very natural to exchange what was in surplus for what they needed or liked but didn’t have, in when others have ego, it’s time for commerce to have shape and scale later on. The process of formation began from the cradle of human civilization in Mesopotamia to the formation of the oldest trade routes and then evolved into a complex network stretching from the Roman Empire in the west to the emperor. Han Empire in the East. Next was the disruption of East-West trade on the mainland as the two empires declined and Islam arose from the Middle East and spread influence, becoming the center of global trade for a long time. At the same time, maritime trade with the Indian Ocean was a major trade route that flourished, replacing the ancient Land Silk Road as the economic lifeblood of the world. Besides the overall picture of the ups and downs of trade history, WJBernstein analyzes the interaction between trade with political, social and other natural factors. For example, the geographical structural differences between the Mediterranean and the Indian Ocean lead to different economic-political, naval strategies thinking among Mediterranean civilizations (such as the Greek). Greece with civilizations participating in the Indian Ocean trading system (Islamic countries in the Middle East, Indian sub-states, Southeast Asia and China). At the same time, he offers interesting examples of times when economic, political and religious interests conflict, forcing rulers to make choices. For example, the famous story when Venice Governor Enrico Dandolo used all his tricks to bring the Crusader army to attack and sack Constantinople, Venice’s influential competitor, instead of attacking Egypt, his partner. commercial importance of Venice, as the Crusaders expected. And not only conscious human endeavors, but at times nature plays an important role in the course of history. The fourteenth century Black Death plague devastated both Christian Europe and the Muslim Middle East, but the consequences were different. The epidemic weakened feudalism in Europe, gave freedom of thought and trade a chance to develop, while at the same time making Islamic civilization severely irreversibly damaged, paving the way for turn in global trade advantage from East to West. In Trade history refers to characters, both famous and anonymous, who contributed to the making of commercial history. It was an anonymous Mesopotamian businessman whose letter on earth kept evidence of a transaction thousands of years ago. It was Vasco da Gama, it was Columbus, the restaurants that paved the way for Europe to regain control of the world. Or Richard Cobden, a pioneer in the fight for free trade thought in the UK in particular and around the world in general. Trading is not only about exchanging goods, but also about competing for the market, competing for monopoly on trading of goods with great profit. Contact between people belonging to far away countries also means the exchange of deadly pathogens. Merchant crews contributed to the spread of the Black Death in Europe. Spanish expeditions made many peoples of the Americas extinct because of the pathogens they carried. Competing for markets, fighting for strategic commodity resources has been the main cause of most wars from ancient times, from the Peloponnese to two bloody World Wars in the twentieth century. WJBernstein has neutrally recounted the story of commerce and its impact on human society, fully pointing out the bright and dark sides of this story. More importantly, we all know this is an ongoing story, and understanding the past is probably the best, if not the only, way to make the future of the dark side of trade possible. control is better, and on the bright side, commercial benefits bring people, to be promoted more thoroughly.

1. Where is the latest named ocean? Icon Atlantic Icon Indian Ocean Icon southern Ocean The correct answer is answer C: The Southern Ocean is the newest ocean to be named. Previously, the Atlantic, Pacific and Indian Oceans were considered to extend as far as Antarctica, the name Southern Ocean did not exist. According to the National Ocean Service. The Southern Ocean is recognized by the US Organization of the US Board on Geographic Names as the water stretching from the Antarctic coast to the 60 degree south latitude line. The boundary of this ocean was proposed to the International Hydrological Organization (IHO) in 2000. This ocean name is widely recognized, however some organizations disagree. The Southern Ocean is 20.3 million square kilometers wide, equivalent to the area of ​​Russia and India combined. Coast stretches for nearly 18,000 km. The average depth is 4,000 – 5,000 m. The deepest point is in the South Sandwich Trench with a depth of 7,236 m. 2. Which ocean is the largest and the deepest? Icon Indian Ocean Icon Pacific Icon Atlantic The Pacific Ocean is the largest and deepest ocean on Earth. With an area of ​​165.25 million km2, this ocean accounts for one third of the total surface area of ​​the globe. All the land on Earth combined (about 150 million square kilometers) still cannot cover the surface of this ocean. The Pacific Ocean stretches from the Arctic Ocean in the north to the Antarctic continent in the south. The widest east-west width is 19,800 km, separating Asia, Oceania from the Americas. The Pacific Ocean has an average depth of 4,280 m. The deepest point of the ocean lies in the Mariana Trench, 10,911 m deep. This is also the deepest point of the Earth’s crust, 13 times the height of the Burj Khalifa – the tallest building in the world in Dubai. If Everest could be placed on the bottom of the Mariana Trench, the world’s highest mountain would still lie underneath the Pacific Ocean. 3. Which ocean is the smallest? Icon southern Ocean Icon Atlantic Icon Arctic Ocean The correct answer is answer C: According to the National Ocean Service, the Arctic Ocean is the smallest ocean on Earth with an area of ​​nearly 14.1 million square kilometers. Even the smallest, it is still nearly 1.5 times larger than the US. The Arctic Ocean borders the United States (the Alaska region), Russia, Canada, Norway and Denmark (the Greenland region). The average depth of this ocean is about 1,205 m, the deepest point is 5,567 m. The Arctic Ocean is almost completely covered by ice most of the year. However, this ocean is not barren. When the ice melts, organisms and nutrients are released into the water. This promotes the growth of algae under the ice. These algae provide food for small organisms, zooplankton, and are a source of food for fish, squid, seals and whales. Some of these larger creatures become prey to polar bears. When the organisms under the ice die, they sink to the ocean floor and feed sponges, anemones and other bottom organisms. 4. Is the Atlantic Ocean larger than the Indian Ocean, right or wrong? Icon It’s correct Icon Wrong The correct answer is answer A: Kindy Data already has a comparison showing that the Atlantic Ocean has an area larger than the Indian Ocean. The Atlantic Ocean is 106.5 million square kilometers wide, covering 20.8 percent of the Earth’s total surface. The average depth is 3,646 m. The deepest point is in the Puerto Rico Trench, at 8,486 m deep. It is surrounded by America to the west, Europe and Africa to the east. The width from east to west is about 9,600 km. Meanwhile, the Indian Ocean is 70.56 million square kilometers wide, covering 13.8 percent of the Earth’s surface. The average depth is 3,963 m. The deepest place is Diamantina trench, 8047 m deep. To the north, this ocean is limited by peninsulas India, Pakistan and Iran, east by Southeast Asia (namely Myanmar, Thailand, Malaysia, Indonesia) and Oceania, to the west by Arab and African islands. The Indian Ocean opens in the south and is bordered by the Southern Ice Ocean. 5. How many tons of gold does the world’s oceans contain? Icon 10 million Icon 20 million Icon 30 millions The correct answer is answer B: Experts estimate that about 20 million tons of gold are still in the ocean. Experts confirm that 1 ton of ocean ore contains about 13 grams of gold, while on land, only 3 to 7 grams of gold per ton of ore. 6. In which sea area is volcanic activity concentrated? Icon South Pacific Icon Indian Ocean Icon Atlantic The correct answer is Answer A: 90% of all volcanic activity on earth is concentrated in the ocean with the largest concentration in the South Pacific. 7. What is the freezing temperature of the oceans about Celsius? Icon -10 degrees C Icon -5 ° C Icon -1.8 degrees C The correct answer is Answer C: Seawater freezes around −1.8 ° C (28.8 ° F). When the temperature of the water drops low enough, ice crystals form on the surface. 8. Which ocean contains the highest salt content in the world? Icon Pacific Icon Atlantic Icon Indian Ocean The correct answer is answer B: Which ocean is the most salty in the world? that is the Atlantic Ocean. In this barn, the average salinity is about 37.9 o / oo. In the Sargasso Sea in the North Atlantic Ocean is the region with the greatest salinity. The reason is that the temperature here is quite high and located far from the mainland, so it does not receive water from rivers and streams. The lightest seawater belongs to the Arctic and Antarctic regions. This is understandable, these are 2 areas with low temperature and continuous rainfall and ice melting.

Sheet South China Morning Post Taiwan announced on April 22 that it would protect its own security, after Japanese Prime Minister Yoshihide Suga said that Tokyo would not engage in the military if Taiwan was attacked. Ms. Au Giang An (Joanne Ou) – spokesperson for Taiwan External Relations – said on April 22: “Self-protection of security is an unshakeable task for us and Taiwan will take on your own responsibility to protect people’s homes and protect this island ”. Ms. Au Giang An (Joanne Ou) – the spokesperson of the Taiwan External Relations Agency. Photo: TAIWAN NEWS Earlier, speaking at the National Assembly on April 20, Prime Minister Suga emphasized that although the US-Japan Joint Declaration, issued after the summit between Mr. Suga and US President Joe Biden, mentioned the issue. But Japanese forces will not engage in any military situation around the island. In response to a question from an opposition politician in the National Assembly on April 20 about the details of Japan’s commitment to Taiwan, Mr. Suga stated “no military participation is expected”. According to the SCMP Analysts say Japan’s constitution will not allow the military to enter the war in the event that China tries to capture Taiwan by force, but Tokyo can provide the United States with logistical and rear-end support. In the statement, Mr. Biden and Mr. Suga called for “peace and stability in the Taiwan Strait”. This is the first time the US and Japan have mentioned the Taiwan issue in a joint statement in more than 50 years. The two sides also said they would counter China’s “threat” in the Asia-Pacific region. The US-Japan statement has aroused strong protests from China, when it warned that Tokyo and Washington should stay away from “internal affairs” related to Taiwan. Over the weekend, the Chinese military’s Eastern Zone, which oversees the Taiwan Strait, deployed dozens of H-6K strategic bombers to participate in a nine-hour live-fire drill. , according to the China Central Television (CCTV) . Previously, the Taiwan External Relations Agency on April 22 said the US-Japan defense alliance is the foundation of peace and prosperity in the Indo-Pacific region. The agency also said the reference in the joint statement reflects the two countries’ strong consensus on security in the Taiwan Strait and Indo-Pacific. “We welcome the international community’s concern about trans-strait peace and stability … and it is our responsibility to protect our security,” the statement said. “Taiwan will continue to liaise and cooperate closely with the US, Japan and other like-minded countries in maintaining stability across the strait as well as maintaining security and prosperity in the Indian Ocean region. – Pacific “- stated clearly. China always considers Taiwan its territory and does not rule out the possibility of using force to unify. The Taiwan-strait relations have been strained since Thai Anh Van, who opposed the “one China” policy, became the island’s leader in 2016.

The statement came days after Japanese Prime Minister Yoshihide Suga stressed that the Japanese military would not engage in any military situation around Taiwan. The Japanese leader asserted that the mention of Taiwan in his joint statement with the United States did not make assumptions about Japanese military involvement. Taiwan claims to defend itself after Japan’s declaration of non-interference. (Photo: EPA-EFE) After meeting at the White House last week, Mr. Suga and President Biden issued a joint statement, which outlined “the importance of peace and stability in the Taiwan Strait”. Both leaders encouraged the peaceful settlement of cross-strait Taiwan issues. In a statement released on April 22, Taiwan’s diplomatic mission said the US-Japan defense alliance is the foundation for peace and prosperity in the Indo-Pacific region and is referenced in a joint statement. reflecting the two countries’ strong consensus on security in the Taiwan Strait and Indo-Pacific. The statement also noted Mr. Suga’s earlier assertion that the dispute in the Taiwan Strait should be settled by peaceful means. “We welcome the international community’s concern for peace and stability in the Taiwan Strait… and it is our responsibility to protect the security of the island. Taiwan will continue to liaise and cooperate closely with the US, Japan and like-minded countries in maintaining stability in the strait as well as maintaining security and prosperity in the Indian Ocean region – Pacific”, the statement clearly stated. China has always asserted that Taiwan is an inseparable territory and does not rule out the possibility of using force to unify the island. The Chinese military’s time increased military operations near Taiwan as tensions between Washington and Beijing escalated.
