April 12, 1981: The HP-41 calculator is used on the first US Space Shuttle flight
The HP-41C series are programmable, expandable, continuous memory handheld RPN calculators manufactured by Hewlett-Packard from 1979 to 1990. The initial model in the series, the HP-41C, was the first of its kind to offer an alphanumeric display; later came the HP-41CV and HP-41CX, which offered more memory and features.
On April 12, 1981, the HP-41 calculator was used on NASA's first space shuttle flight, a tiny calculator that allowed astronauts to calculate the exact angle at which they would need to re-enter Earth's atmosphere. Today, an HP-41C, which flew nine early Space Shuttle missions, is on display at the National Air and Space Museum in Washington, DC. In the early space shuttle missions, the HP-41C could perform trivial but necessary daily calculations, such as calculating the center of gravity change caused by fuel consumption; in addition, in the event of a main computer failure, the HP-41C could also be used temporarily, Precisely determine the re-ignition time.
The digital LCD screen of HP-41C has completely changed the way of using pocket calculators, and its programmability is closer to that of our common scientific calculators today; HP-41C is also the world's first calculator that can display letters. Allow the calculator to accurately display error messages, rather than simply displaying a blinking zero; it can also explicitly prompt the user to enter parameters, rather than just displaying a question mark.

April 12, 2006: Google's Chinese name Google released
On April 12, 2006, Eric Schmidt, Google's chief executive, and two Google vice presidents in China, Kai-fu Lee and Shaoning Zhou, jointly released Google's global Chinese name "Google", which means "Google of Google". It represents "Song of Sowing, Song of Expectation, Song of Harvesting, Song of Joy". It is worth mentioning that the English name Google was originally googol, which means 10 to the 100th power, a super large number, representing "obtaining massive resources through searching on the Internet", and later misspelled it into google.com when registering the domain name , so the wrong will be wrong.
Tracing back the history between Google and China, as early as September 12, 2000, Google, which was established for one year, announced that it would add two languages, Simplified and Traditional Chinese, to its website and began to provide Chinese search services. Languages added on the same day include Japanese and Korean, representing the company's determination to enter the Asian search market. According to Bull, almost half of the site's traffic comes from outside the United States. Google announced a month ago that it had signed an agreement with Chinese portal NetEase to use Google as its Chinese-only search engine and default web search results provider. Google says it has indexed 24 million Chinese web pages. Because the server is located overseas, Google's access in China was slow, and it was blocked many times in the following years.
On September 10, 2004, Google launched the Simplified Chinese version of Google News, allowing users to search and browse news from more than 1,000 Simplified Chinese news sources. Google invited Netease News for an exclusive interview for the first time, which was regarded as an action to accelerate its China strategy after its listing. Unlike the news channels of typical web portals, Google News displays headlines selected entirely by computer algorithms without human intervention. The website editors of Sina, Sohu, and Netease said in interviews that they were not optimistic about the algorithm selection; the director of Sina Technology said, "Website editors know what netizens want to see best, and our criteria for selecting news are much stronger than computers."
On January 11, 2006, Google launched the Chinese version of academic search. The index sources include Wanfang Data Resource System, VIP Information, and the content covers publicly published academic journals and papers. Subsequently, in order to prepare for the work of Google China in the same year, the Chinese version of the website Google.cn was officially launched on January 26, 2006. This is also the first website launched by Google that operates in China. On September 4, 2006, Google officially opened the Kejian Building with a total construction area of 14,000 square meters in the Tsinghua Science and Technology Park in Zhongguancun, Beijing, as the headquarters of Google China.
After selecting the address, on January 4, 2007, Google announced a cooperation with China Mobile Communications Co., Ltd. to provide mobile search technical support for China Mobile's WAP portal "Monternet". In February of the same year, Google officially launched the Chinese version of Google Maps during the Spring Festival, and gradually Chinese cultured its popular products within this year. On October 30, 2007, Google launched the short domain name "g.cn" in China. This domain name was originally owned by Cai Wensheng, the president of 265.com, an Internet navigation website established in 2003. At that time, there were rumors that Google China would acquire 265.com, and the reason for this was to obtain this domain name.
In 2008, in response to the large number of casualties and economic losses caused by the Wenchuan Earthquake, on May 15, Google integrated information about the earthquake using maps, come, Q&A, and search services. On the 18th, Google launched Family Search (www.google.cn/qinren), which supports the release of information about finding relatives and reporting safety. The service originally contained information on 40 hospitals and more than 40,000 people, but users can also submit the status of friends they know to Google through text messages or web pages, and they will be added to the database after verification.
According to Google Hot List data, in 2009 the most popular search keyword in mainland China was "Baidu"; on September 4 of the same year, Kai-Fu Lee, president of Greater China, officially announced his resignation. On January 13, 2010, Google made a statement saying that they would consider abolishing the content review of google.cn. If the negotiation fails, Google China may be shut down. This triggered a big discussion among Chinese netizens. On March 23, 2010, Google announced its formal withdrawal from China. As for the core reason for Google's departure, there are still different opinions until now. Did Baidu defeat Google? Is Kai-fu Lee the leader's problem? Or is there something wrong with Google itself? Welcome to vote and comment in this issue, and share your insights.
