Is our country’s education system rubbish?
Each country has its own environment and cultural traditions and cannot be generalized. Textbooks and courseware from the Massachusetts Institute of Technology in the United States are published online for free, and Chinese people all over the world are also volunteering to translate them. Anyone can learn it, and there are so many people who can pass the exam. How many countries can be like him?

The pen is blocked
What is the best way to solve the problem of blocked pen
After decomposition, wipe it with a toothbrush under running water; disassemble the 1.5 mm diameter ventilation tube and the multi-slot phenolic resin bakelite, insert them respectively with a medical syringe and clean them with a jet.
From the perspective of the metallurgical industry, it is impossible to produce high-grade corrosion-resistant, low friction coefficient, and wear-resistant pen tips and pen body alloys. This reflects the quality of key military materials, industrial bearings, etc., and is the strength of national defense. vivid manifestation.
From the perspective of manufacturing, high-end special production equipment must be imported. The automatic production equipment for various pens produced in Germany generally costs 3 million yuan per unit. It does not occupy a large area and has good horses. To assemble a good saddle, the materials and accessories used must also be imported. Therefore, ballpoint pens have been produced since before the Cultural Revolution, but until now, the quality is not up to par; the good ones are produced on imported production lines, and some inks are also imported; the technology for producing pen tip rollers is also a true reflection of national defense strength, and can produce precision in large quantities at low cost. The country that produces carbide beads and ceramic beads has an excellent equipment production industry and is invincible in the field of ceramic bearings and other military equipment! !
Moreover, there are no longer a large number of excellent pen repair personnel. In the past, old department stores had such repair points that could re-weld the pen tip and polish it. Because everyone has writing defects, the pen tip gradually deteriorated. The pen is ground to the wrong angle, and the gold-containing feed feels good when writing. If the pen tip is broken, you have to weld the pen tip and keep the pen feed. Those who go to primary schools to repair pens want to defraud primary school students of their valuable pen feeds.
The ability to repair pens by yourself is a reflection of the national quality and the theoretical level of thin shell mechanics. Does your pen feel astringent when writing? Not smooth? Don’t miss such a good opportunity to practice, don’t leave it to others, practice it yourself! This is consistent with the art of sheet metal craftsmanship and adjusting bicycle spokes.
The popularization of computers and printers will attack Chinese culture and destroy Chinese calligraphy.
Compared with traditional fountain pens and ballpoint pens, ballpoint pens waste a lot of non-renewable resources on the earth and cause huge damage to the environment. When most people return to using traditional fountain pens, they have entered an era of extreme scarcity of resources on the earth. .
In the early days of reform and opening up, teachers in colleges and universities concentrated on discussing the direction of teaching. The conclusion was to basically cancel the teaching of analog circuits and only retain it in form, because the price and performance of foreign integrated circuits are higher than those of domestic traditional discrete circuits. Circuits built with components cannot be replaced. From then on, teaching, vocational education, and home appliance repair all centered on integrated circuits. Later, it developed into the information age, with computer technology and network technology as the top priority, and the core of the development of science and technology. .
On the road, trenchless technology has been popularized, and directional drilling technology has been widely used in laying underground pipelines in cities. China has been able to imitate this kind of underground drilling rig with a drill pipe that can turn. An imported set costs 1 million yuan, and it is domestically produced. A set of 400,000 yuan; while the guided ground penetrating radar has to be imported, a unit with general performance is about 300,000 yuan; nowadays, urban construction, gas pipeline construction, underground cable construction, and water supply system construction are all indispensable for this kind of radar; houses Decoration and property management require smaller ground-penetrating radars, which cost 180,000 yuan each. Traffic police speed radar is similar. The highly sensitive detection instrument used by the Gas Company to detect gas leaks in thin pipes under the road is produced in Germany. Each instrument costs one million yuan, and it is also an analog instrument.
Looking at high-end instruments for deep space exploration, bioengineering, medical instruments, analytical instruments, high-energy physics research, biological origins, archaeological research, and criminal investigation, imported instruments dominate the world. Based on simulation technology. For example, the Hubble Telescope, black hole exploration, gravitational wave detection, and satellite photos are the data obtained by using them. Inertial guidance systems, mobile phones, base stations, computers, televisions, cameras, scanners, cameras and other information equipment, the input and output are mostly analog processing, but digital processing is used in the middle. Nowadays, analog and digital hardware parts and even software are integrated. Without basic design capabilities and semiconductor process equipment, we can only use system integration methods. Our superior strength and greatest ability are algorithms and the use of DSP. To put together a big platter of products on the market, we must use other people's core hardware and software. The back door was wide open, introducing a safety hazard. Therefore, in theory, it is a mid-air crane, but in application, it is the final consumer, and it will always be at the downstream of the industrial chain.
The proposal of Einstein's theory of relativity was based on the use of advanced hardware at that time to obtain a large amount of physical and astronomical experimental and observational basic data; there are many undergraduates and graduate students in corresponding majors who have no real understanding of the basic components of circuits. , under this premise, relying on circuit simulation software cannot make a decent basic circuit.
So students should first use analog pointer multimeters to build perceptual understanding and imagination. Chinese people are good at abstract thinking because the cultivation period of deep and correct intuition is long and expensive, and there are few people who can cross the threshold; In comparison, it is too easy to play around with mathematics and English, memorize formulas, solve exercises, and cite literature.
With the common teaching methods, syllabus, textbooks, experimental devices, and innovative projects in China over the past few decades, it is impossible for even Peking University and Tsinghua University to cultivate people who can design circuits proficiently. The most basic education is to conduct complete design and debugging of at least ten basic circuits; and then to conduct systematic design and overall joint debugging of more than ten application combination designs.
There are many countries that can build satellites, launch vehicles, and nuclear weapons, and a sign that represents their industrial base and overall innovation capabilities is how much of their basic materials, precision processing equipment, and precision instruments are made domestically. ? What is the international level of basic industries? I have worked in a military industry company, and I know that the key technologies in the defense industry of various countries are bought and sold based on the strength of the country. The result is industrial products produced by others on a large scale. Even if you use higher production costs to manufacture them, they will not be as good as others. performance and reliability. Under the conditions of weak industrial infrastructure, imperfect modern industry, and poor national quality, and under the pressure of keeping up with the development of the world and the urgent demands of the economic form, we can only focus on information construction, which will inevitably be stretched. , it is time to fill the gaps; cutting corners and materials in house construction has caused hidden dangers, causing disharmony among neighbors and constant disputes. As a result, the waterproofing and leak-proofing industry has prospered, and social resources have been wasted and consumed. If you pay a little attention and spend a little money when building a house, you can No worries.
It is recommended to carry out free online video tutoring activities, record the entire process with high-definition video, and compile and publish it publicly.
The above content was independently written and typed verbatim on the Baidu website. In the future, academicians, doctoral supervisors, deans, principals, and ministers should be responsible for answering these questions online.
What is an analog circuit? The most difficult and basic thing, under the premise of limiting discrete components and general-purpose integrated circuits, is something that undergraduates can't do, and postdocs can't do anything about it. This skill is so tough! ! ! Unlike math problems and foreign language homework, it can be solved by raising one academic level; doing business, making political achievements, playing stocks, and high investment amounts can cover up the problem, which will not work here! ! Whether it's analog circuit technical indicators, special functions, analog computers, etc., it's all hard work! ! ! Many parameters can be calculated or debugged, and they are all based on evidence. This is not a technique for downloading circuit imitation to achieve the same effect, but a complex and flexible way of thinking about space and time. Market supply conditions and customers must also be fully considered. requirements, the highest level in developed countries. The way of thinking about mechanical mechanism design and special processing technology is also similar. I am good at this and have contacted many publishing houses, willing to provide a full set of innovative textbooks from basic circuits to high-performance application examples. However, they are not willing to publish. What they want is original textbooks translated from abroad or plagiarized foreign textbooks. We are now seeking sponsorship from large companies. Please contact the Director of the Overseas Chinese Affairs Office of the State Council for details. Analysis of the current situation and countermeasures of China's industrial development under the economic crisis will make competitive advanced product design information, process know-how, processing techniques, debugging principles, and sales strategies completely public for free, allowing companies to simplify and industrialize them. I contacted the publishing department, but they wouldn't do it. A person's first cognition is the most important. Today's teachers are generally low in level and ability. They cannot cross the threshold and cannot answer students' questions in the classroom, laboratory, graduation project, and dozens or hundreds of pages of mathematical formulas. , they are all copied from foreign original books, and then the third-person translator plagiarizes the translated and published textbooks. The basic circuits cannot be designed or debugged, so your youth is wasted! What are the characteristics of the circuit structure of high-frequency power amplifiers? I have a deep understanding and debugging details of high-frequency power amplifiers with high efficiency, high reliability, and no tube burning. Since I was forced to lay off my job, I will not introduce them. After I was laid off, I still retained more than a thousand high-frequency ceramic skeleton coils. The high-frequency current output by a 3DG12 oscillation was coupled through a capacitor to light up the tube radio indicator light bulb. This is a rated voltage of 6.3V and an operating current of More than 100 mA incandescent lamp. I have been in contact with many publishing houses for more than 30 years, but they are all unwilling to publish it. It was originally supposed to be sold at a cost price of tens of yuan per set, together with debugging details, and it involved many kinds of actual circuits and was an existing scientific and technological book. , content that is not included in the textbooks, and the imported version of the solid circuit textbook does not have these contents. Under the administrative order of deputy-level and senior-level cadres, these high-frequency ceramic skeletons were also completely destroyed by the Gardening Department. Take low-frequency analog circuits as an example. When undergraduates are incapable of doing anything, it will be useless to go to graduate school. This is different from mathematics, foreign languages, Chinese, mechanical processing, bioengineering, etc. Some students cannot solve the college entrance examination questions, so they need to get a higher degree. It is possible to make it. If a primary school student is not good at translating and writing, a highly educated person will do it, but he will not be able to create a masterpiece. If this part cannot be processed, imported processing equipment will solve the problem, but the level of material manufacturing will always linger. No progress has been made; this research-level subject under genetic conditions cannot be completed. It can be achieved by introducing imported reagents and equipment and referring to the latest foreign literature. However, the localization of imported reagents has been difficult to overcome; and no matter how skilled bicycle thieves and locksmiths are, , they cannot manufacture the precision mechanical locks of developed countries; no matter how skilled clinicians and surgeons are, they cannot manufacture advanced diagnostic instruments, surgical instruments, and medicines; no matter how long the accumulated safe flight time of airplane pilots is, they have flown through complex climates. , environmental conditions, it is impossible to build a large aircraft or a high-performance aircraft.
Making hardware is very time-consuming and expensive. Without decades of continuous experience, no financial support, no production practice verification, and no practical business suggestions, it is empty talk, and people who can get through it are very rare. One is The elimination rate is high. First, there is no money and time support. More importantly, many people, at the end of their lives, do not know where they went wrong? What didn't get done? Basically, I don’t know what the best approach was under the historical conditions and environmental constraints at the time? He is still excellent in all subjects, and getting the top score in the college entrance examination is very affordable and persuasive! ! ! Employment is the overriding priority and the foundation for human survival! ! ! Should the government give money to the poor? All information on the design, processing, adjustment, and parts procurement locations of the science and technology museum exhibits should be disclosed to teach people how to fish and improve the quality of the entire nation and citizens. Today’s textbooks are full of copies. Nowadays, system integration and high-tech assemblers are all fashionable. Just spend money on them. Of course, the country's strategic secrets must be kept strictly confidential, and commercial secrets must be protected by the beneficiaries.
Academic research conducted abroad using social resources is generally fully open to the public. Many of China's researches completed with state resources should be made public, and textbooks and experimental books in higher education institutions should be made public, otherwise academic corruption will be exacerbated! This is a reflection of responsible use of state and social resources. In China, knowledge is publicized, and competition between substantive content and technical means is made public. Actual devices can be copied for free by third parties, technical indicators can be measured by independent third parties, and performance comparison data and indicators are made public. This is the key to completely improving the cross-border basic education. The only way to overcome the threshold if it takes too long is for the state to pay the relevant fees; this cannot be replaced by plagiarism. The next-generation keyboard I designed 25 years ago has been released internally to several industries for free because there is no funding for patent applications or a laboratory. Provide innovative exhibition items to science and technology museums and popular science exhibition halls, disclose all design, procurement, processing, debugging, and maintenance information to improve the basic quality of citizens across the country. Who can tell me something about the 1970s and 1980s? It needs to be close to life. Just talk about the experiences of the older generation. In the 1970s, teaching materials, industrial equipment, and technological innovation materials were completely open to the public. The whole country learned from each other and communicated with each other without reservation. The utilization rate of raw materials and equipment is the highest. Spare parts from various machine tools, automobiles, wire cutting machines, EDM machines, water pumps, internal combustion engines, electric motors, clocks, bicycles, lamps, etc. are universal and interchangeable across the country, and the basic drawings are public , National unified design of DDZ instruments, National unified design of N1 clock cores, etc. In the 1980s, diplomas, academic qualifications, and professional titles had the final say and were introduced across the board. In the 1990s, low-level repeated research was blocked and hostile to each other. Low-end products were kept secret. As long as similar products were from different manufacturers, components with the same function were deliberately made without interchangeability, which greatly consumed social resources and harmed consumers. In order to make more money and cheat more money, people artificially create troubles, maintenance difficulties, and all obstacles. I have proposed to the national, provincial, and municipal science and technology museums to provide innovative exhibition items, to fully disclose all design, processing, assembly, and adjustment information to visitors, and to disclose the procurement locations of raw materials, equipment, and accessories. What is the purpose of the university? No matter how high your academic qualifications and professional titles are, if you cannot design and manufacture teaching aids, design and manufacture teaching instruments, or repair instruments and equipment; you will be the best if you use your parents’ money to import teaching instruments and imitate them from commissioned factories; if you use your parents’ money to import teaching instruments, you will be the best. Use your parents' money to hire people outside the school to repair equipment and purchase accessories from outside the school; use your parents' money to hire teaching equipment manufacturers to provide teaching experiment handouts, and fill in the author's name to get the Outstanding Teaching Achievement Award; teach you to recite the formulas and Foreign languages ??can never compare to the content of textbooks published online by the Massachusetts Institute of Technology in the United States.
If graduate students cannot produce a paper, they will buy it, not only the paper, but also the space of various academic journals. Therefore, selling space has become a common practice, further damaging the quality of academic journals. The current situation is that China has the largest number of college students in the world, and China also has the largest number of published papers in the world. However, its scientific research competitiveness has been declining year by year, and its basic industrial capabilities have not substantially improved, and it still lags behind the number of developed countries. ten years. This is true for publications in core journals and papers, as well as for so-called topics. Often, the bigger the official, the more topics there are, and of course, the less time they have to do them (this is assuming that they are all knowledgeable), so they can only be done by students. Therefore, graduate students become the tutor's wage earners, cheap labor. One can only imagine the quality of such a subject. From the teacher’s basic level, moral bottom line, innovation ability, sense of responsibility, minimum sense of morality, and from the comparison of every detail of Chinese bicycles and bicycles in developed countries, you can clearly distinguish the substantive level of such topics and papers. That's clear. School teachers must come up with something to make up for the regular evaluations, otherwise they will be laid off. Of course, if the output is high, there are rewards, especially if you publish articles in so-called A-level and B-level publications, the bonuses are very considerable. Should we combine anti-crime and anti-corruption campaigns? So do counter-terrorism and anti-corruption need to be combined? Please tell me your views on the causes of the current world economic crisis. Therefore, we must severely crack down on the four villains of political hooligans, academic hooligans, economic fraud, and underworld leaders. What is bourgeois liberalization? It means that professors cannot start from the basics and rely on imported modules, reagents, integrated circuits, computers, instruments and equipment from abroad, and they also coerce the government to bloodletting and support "high technology", which is consuming and wasting social resources. What kind of equipment and technologies are scarce in China? Intellectuals with ill health are not short of importing the most advanced equipment and analytical instruments in the world. For example, China has imported a lot of top-notch equipment such as Haas gear processing equipment; China is not short of huge research funds. It just cannot be used as a basis to create top-level mechanical equipment. The second prototype of the next generation keyboard was hand-made on the side of the road, and the Chinese, as visitors, mentioned that it was illegally displayed at the exhibition to the Japanese in the booth, and they were about to put it on their booth for filming; A large Japanese company used more than a dozen Chinese technicians to translate over a hundred pages of basic information and send it back to the country. The Overseas Chinese Affairs Office 8 forces designers and manufacturers to retire early. For more than 20 years, designers and manufacturers have had no equipment, work funds, or workplaces; those with high professional titles and high education who have high scientific research funds are not good at engineering technology or theoretical analysis. , cannot go beyond this level. What do you think China still lacks? Jiang Shuzhuo accused himself of often improvising on the spot to answer questions students encountered in graduation thesis and innovation projects, stealing the spotlight and covering everything from design skills, processing industries, algorithms, and patent document writing rules. However, his highly educated and professional staff The characters are uneducated, stunned, and under pressure, they implement reverse elimination and force themselves to be laid off and unemployed early. This is destroying basic education and combating innovation. /question/88844575.html?si=1
Things thrown upstairs to the ground floor (we live on the ground floor) are dirty and messy. We want to put a note on the residents upstairs to tell them not to throw them away. What should I write about littering?
