Chat means chat, and GPT is the acronym for Gene Rate Pre trained Transformer. Genrative means generation, and its function is to create or produce something new; Pre trained refers to a model of artificial intelligence that is learned from a large amount of textual materials, while Transformer refers to a model of artificial intelligence. Don't worry about T, just focus on the words G and P. We mainly use its Generative function to generate various types of content; But we need to know why it can produce various types of content, and the reason lies in P. Only by learning a large amount of content can we proceed with reproduction. And this kind of learning actually has limitations, which is very natural. For example, if you have learned a lot of knowledge since childhood, can you guarantee that your answer to a question is completely correct? Almost impossible, firstly due to the limitations of knowledge, ChatGPT is no exception, as it is impossible to master all knowledge; The second is the accuracy of knowledge, how to ensure that all knowledge is accurate and error free; The third aspect is the complexity of knowledge, where the same concept is manifested differently in different contexts, making it difficult for even humans to grasp it perfectly, let alone AI. So when we use ChatGPT, we also need to monitor the accuracy of the output content of ChatGPT. It is likely not a problem, but if you want to use it on critical issues, you will need to manually review it again. And now ChatGPT has actually been upgraded twice, one is GPT4 with more accurate answering ability, and the other is the recent GPT Turbo. The current ChatGPT is a large model called multimodality, which differs from the first generation in that it can not only receive and output text, but also other types of input, such as images, documents, videos, etc. The output is also more diverse. In addition to text, it can also output images or files, and so on.

The returner of the Chang'e-6 lunar probe is opened during a ceremony at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation in Beijing, capital of China, June 26, 2024. The returner of the Chang'e-6 lunar probe was opened at a ceremony in Beijing on Wednesday afternoon. During the ceremony at the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, researchers opened the returner and examined key technical indicators. Photo: Xinhua As the US space industry recently faced yet more delays and stagnation with key components including manned spacecraft and space suits "going wrong," NASA has once again resorted to its "sour grapes" rhetoric upon seeing China's successful retrieval of fresh lunar soils from the far side of the moon, by claiming that China did not directly invite its scientists to participate in the lunar soil research. This behavior is a typical blame-shifting trick, Chinese experts said, noting it is clear to all that it is the US' own laws, not China, that are restricting space cooperation between the two sides. Instead of deceiving themselves by distorting the truth, the US should face up to its own problem of overall weakening engineering capability and the lack of long-term planning in its space industry. After the Chang'e-6 samples, weighing nearly 2 kilograms, were safely transported to a special laboratory for further study on Friday, NASA spokesperson Faith McKie told media that while China worked with the European Space Agency, France, Italy and Pakistan on this mission, "NASA wasn't invited to take part in the moon probe." NASA also didn't get "any direct invitation" to study China's moon rocks, after it welcomed all scientists from around the world to apply to study them, McKie told NatSec Daily. Responding to the remarks, Chinese Foreign Ministry spokesperson Mao Ning told the Global Times on Monday that China is open to having space exchanges with the US, and we also welcome countries around the world to take part in the study of lunar samples. "However, the US side seems to have forgotten to mention its domestic legislation such as the Wolf Amendment. The real question is whether US scientists and institutions are allowed by their own government to participate in cooperation with China," Mao said. "The existence of the Wolf Amendment has basically shut the door to space collaboration between the two countries," Wang Yanan, chief editor of Beijing-based Aerospace Knowledge magazine, told the Global Times on Monday. Even if research institutions of the US have the willingness to work with China on opportunities such as lunar sample research, institutions there must obtain special approval from the US Congress due to the presence of this amendment, Wang explained. Currently, no such "green light" is in sight from the Congress. Furthermore, China's collaboration with international partners is based on equality and mutual benefit, leveraging their respective scientific resources, facilities, and expertise. However, the US only wants what it doesn't have, and its engagement with China would be advantageous only to itself, Wang noted. NASA has found itself embroiled in a number of thorny issues recently, with the latest being Boeing's Starliner manned spaceship experiencing both helium leaks and thruster issues during a June 6 docking with the International Space Station (ISS), which led to an indefinite delay for its crew's return to Earth, despite NASA's insistence that they are not "stranded" in space. The return of the Starliner capsule, while has already been delayed by two weeks, will be put on hold "well into the summer" pending results of new thruster tests, which are scheduled to start Tuesday and will take approximately two weeks or even more, per NASA officials. Previously on June 24, NASA cancelled a spacewalk on the ISS following a "serious situation," when one of the spacesuits experienced coolant leak in the hatch. While being broadcast on a livestream, the astronauts reported "literally water everywhere" as they were preparing for the extravehicular activity, space.com reported. The report said that this is the second time this particular spacewalk was postponed, after a June 13 attempt with a different astronaut group was pushed back due to a "spacesuit discomfort." The recurring issues with the spacesuits are due to their much-extended service lifespan, media reported, as the puffy white ones US astronauts currently wear were designed more than 40 years ago. Despite the pressing need to replace them, NASA announced recently that it is abandoning a plan to develop next-generation spacesuits, which had been committed to be delivered by 2026, CNN reported on Thursday. One of the root causes for such problems is that the US has developed many large technology conglomerates, which for a long time have benefited significantly from government orders and industry monopolies. Consequently, in many complex engineering fields, the level of attention given is greatly insufficient, Wang noted. It also reflected the US' lack of long-term strategic planning for its manned space program. For instance, the ageing spacesuits should have been replaced a decade ago to ensure that operational suits remain in usable condition. Failure to address this issue results in a hindrance to the space station's necessary maintenance tasks and even poses life-threatening risks to astronauts in emergency situations, experts said. The issues with Boeing's spacecraft and the spacesuits are not isolated problems, but reflected a systemic issue in the US space industry - the overall weakening of engineering capabilities, they noted.

On the afternoon of July 8, local time, the Vietnamese Ministry of Health issued a notice stating that an 18-year-old girl in the country died of diphtheria. The Ministry of Health asked Nghe An Province and Bac Giang Province to take urgent action to control the epidemic. Diphtheria is an acute respiratory infectious disease caused by Corynebacterium diphtheriae, which is mainly transmitted through droplets and can also be indirectly transmitted by contact with objects containing Corynebacterium diphtheriae. Severe cases may show symptoms of poisoning throughout the body, complicated by myocarditis and peripheral nerve paralysis.

New York CNN — A record number of passengers are expected to pass through US airports this holiday travel week. You’d think this would be a great time to run an airline. You’d be wrong. Airlines face numerous problems, including higher costs, such as fuel, wages and interest rates. And problems at Boeing mean airlines have too few planes to expand routes to support a record numbers of flyers. Strong bookings can’t entirely offset that financial squeeze. The good news for passengers is they will be spared most of the problems hurting airlines’ bottom lines — at least in the near term. Airfares are driven far more by supply and demand, not their costs. But in the long run, the airlines’ difficulties could mean fewer airline routes, less passenger choice and ultimately a less pleasant flying experience. Profit squeeze Industry analysts expect airlines to report a drop of about $2 billion in profit, or 33%, when they report financial results for the April to June period this year. That would follow losses of nearly $800 million across the industry in the first quarter. Labor costs and jet fuel prices, the airlines’ two largest costs, are both sharply higher this year. Airline pilot unions just landed double-digit pay hikes to make up for years of stagnant wages; flight attendant unions now want comparable raises. Jet fuel prices are climbing because of higher demand in the summer. According to the International Air Transport Association’s jet fuel monitor, prices are up 1.4% in just the last week, and about 4% in the last month. Adding to the airlines’ problems is the crisis at Boeing, as well as the less-well-publicized problems with some of the jet engines on planes from rival Airbus. Since an Alaska Airlines Boeing 737 Max jet lost a door plug on a January 5 flight, leaving a gaping hole in the side of the plane 10 minutes after takeoff, the Federal Aviation Administration has limited how many jets Boeing can make over concerns about quality and safety. As a result, airlines have dramatically reduced plans to expand their fleets and replace older planes with more fuel efficient models. In some cases, airlines have asked pilots to take time off without pay, and carriers such as Southwest and United have announced pilot hiring freezes. In addition to the problems at Boeing, hundreds of the Airbus A220 and A320 family of jets globally have also been grounded for at least a month or more to deal with engine problems. Just about all the planes with those engines have been out of sevice for at least a few days to undergo examinations. And Airbus has also cut back the number of planes it expects to deliver to airlines this year because of supply chain problems. Problems for flyers For now, competition in the industry remains fierce: There are 6% more seats available this month compared to July of 2023, according to aviation analytics firm Cirium. And that’s helped to drive fares down — good news for passengers, but more bad news for airlines’ profits. Southwest announced in April that it would stop serving four airports to trim costs — Bellingham International Airport in Washington state, Cozumel International Airport in Mexico, Syracuse Hancock International Airport in New York and Houston’s George Bush Intercontinental Airport. Many more cities lost air service during the financial hard times of the pandemic. While upstart airlines are driving prices lower for travelers, those discount carriers might not survive long term. As the major carriers are making less money, many of the upstarts are flat-out losing money.
