Students in the era of artificial intelligence who need "nomadic"

A year ago, the AlphaGo robot developed by Google Company defeated the human master of Go. This iconic scene in the history of artificial intelligence has sparked shocks in many areas, including traditional education.

"When the era of artificial intelligence comes, what advice do you have for young people?" For this question, Li Jiange, dean of the Guangdong Institute of Technology, answered: "I will tell my students that you need to be careful, but you need to be careful, but you Always be prepared to change your profession."

On March 18th, the China Development High-Level Forum hosted by the Development Research Center of the State Council set up an issue – “Educational Challenges and Innovations in the Age of Artificial Intelligence”.

On February 22nd, in London, England, the Blanca Lee Dance Company staged a robot to dance with people.

Chang Boyi, CEO of Roland Berger International Management Consulting, expressed his feeling at the forum that the future education system should be developed as “nomadics” who can switch freely between different industries and different positions instead of I have been locked in a certain industry and a certain position for a lifetime.

The advice of the board of directors of McKinsey, Bao Damin, to young people is: "Lifelong learning."

In a report, McKinsey said that by 2030, after more than a decade, 45% of human activities could be replaced by artificial intelligence. It is not as simple as replacing the human arm with a robotic arm. Even some decisions of the CEO can be be replaced.

Bao Damin said that artificial intelligence will bring new employment opportunities while destroying some rice bowls. For the education industry, the challenge is how to prepare educators to adapt to the future world. "I think the key is that the cycle of education should be shortened, and it is necessary to introduce new ones as soon as possible."

In a mining area in Canada, artificial intelligence replaced the work of the previous 236 workers and increased efficiency by 40%; on Wall Street, due to competition from machines, an investment bank trader reduced from 600 at the peak to only 2 People; until the unmanned technology matures, global full-time car drivers may face unemployment... But Bao Damin stressed that this is only a starting point, and all walks of life will be affected. He believes that artificial intelligence is the second trend in technology development. Humans now have more data, higher computing power and stronger connectivity than ever before. "If the book is 100, we will now turn to the first or the second chapter, it is difficult to predict the impact of future artificial intelligence."

Bao Damin believes that a series of changes have put forward requirements for the transformation of the existing education system. He said that if you look at a photo of a kindergarten in Manhattan, New York, compared to the photos 20 years ago, the difference is actually not big. There have been no major changes in the field of education over the years. We need to reflect.

Now, Li Jiange plans to set up more elective courses in the Guangdong Institute of Technology, led by him, to reduce the proportion of compulsory courses. “Because we feel that in the development of artificial intelligence, the integration of disciplines and cross-border integration is very important.” He said that what is needed now is a variety of interdisciplinary talents, to encourage students to be interdisciplinary rather than limited. In the original professional settings.

"It turns out that distance education is not a substitute for classroom education because it has no interaction. But now with the emergence of artificial intelligence, online education can also interact and answer questions. So I think that the development of artificial intelligence will also be very useful for existing education. Big challenge." Li Jiange said.

The president of Yale University, Su Bide, does not think that online education will replace the feeling of sitting in the classroom and learning together with teachers and students. However, he advised his students to “learn how to learn” rather than just learning.

“It’s very difficult to know what the future of higher education looks like,” said Subid, in an interview with the China Youth Daily and China Youth Online. “What I can tell you is that the education we provide is not currently available. Prepared for job opportunities and challenges. We don't know why we educate, so it's important that we shape lifelong learners with universal skills."

Liu Zunyi, former president of the Chinese University of Hong Kong, believes that one of the effects of artificial intelligence on education is that everyone can afford their own "private teachers." He said that Confucius put forward the concept of "teaching students according to their aptitude" more than 2,000 years ago. This idea can be better achieved through artificial intelligence. From kindergarten to postgraduate education, artificial intelligence that enables accurate analysis at every step of the game can help to identify the individual needs of each student and then tailor the education for them.

Liu Zunyi is not too worried about the problem of robots grabbing work. He believes that even if this problem exists, it is also a "transitional" problem. There are some jobs, such as brushing the toilet, which humans are not willing to engage in. It is nothing wrong with being replaced by machines.

“Artificial intelligence will make some jobs become insignificant or even completely canceled, but artificial intelligence will also bring new demands, which also brings us opportunities.” Su Baide said that when we are now educating, In fact, it is not clear which areas of employment in the future. General education should be strengthened so that students become innovators when faced with a new round of liberation of productivity. Students in all disciplines need to cope with such changes.

"People are more difficult in the process of transformation, mainly because our original education and everyone's concept are more accustomed to a career in a lifetime." Li Jiange said, and now everyone has to accept lifelong education, constantly transforming , constantly adapting, "I actually think that if we change a perspective, this is also a very fun thing. If people can engage in many interesting careers in their lifetime, it should be seen as a kind of happiness, not a pain." .

Surge Protection Device SPD

Product Description

SPD Surge Protective Device,Lightning Surge Protector
Surge Protection Device (SPD)

It is a device used to limiting instant surge voltage and discharge surge current, it at least including a non-linear component.

Surge protective Device Model Selection

With the impact of international information flow, the rapid development of microelectronic science and technology, communication, computer and automatic control technology, make the building start to go for high quality, high functional area, formed a new building style-intelligent building. As inside the intelligent building there are lot of information system, <<Building lightning protection design norm>> GB50057-94(2002 vision)(hereafter brief as <<lightning protection norm>>) put forward the relative requirement to install the surge protective device, to ensure the information system safely and stable running.
SPD essentially is a equipotential connection material, its model selection is according to the different lightning protection area, different lightning electromagnetic pulse critical and different equipotential connection position, decide which kind of SPD used in the area, to achieve the equipotential connection with the common earth electrode. Our statement will based on SPD's maximum discharge current Imax, continuous operating voltage Uc, protection voltage Up, alarm mode etc.
As per << Lightning Protection Norm>> item 6.4.4 stipulation "SPD must can withstand the expected lightning current flow and should confirm to the additional two requirements: the maximum clamp voltage during surge across, capable to extinguish the power frequency follow-on current after lightning current across." That is the value of SPD's max. clamp voltage add its induction voltage of two ends should be same with the system's basic insulation level and the equipment allowed max. surge voltage.

SPD for Power Supply System Series Selection Guide

The installation of SPD at each lightning protection zone, according to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category, its insulation withstand impulse voltage level can determine the selection of SPD. According to the standard of low voltage electrical appearance, make classification of electrical equipment in accordance with the over voltage category as signal level, loading level, distribution and control level, power supply level. Its insulation withstand impulse voltage level are:1500V,2500V,4000V,6000V. As per to the protected equipment installation position different and the different lightning current of different lightning protection zone, to determine the installation position of SPD for power supply and the break-over capacity.
The installation distance between each level SPD should not more than 10m, the distance between SPD and protected equipment should as short as possible, not more than 10m. If due to limitation of installation position, can't guarantee the installation distance, then need to install decoupling component between each level SPD, make the after class SPD can be protected by the prior class SPD. In the low voltage power supply system, connecting an inductor can achieve the decoupling purpose.
SPD for power supply system specification selection principle
Max. continuous operating voltage: bigger than protected equipment, the system's max. continuous operating voltage.
TT System: Uc≥1.55Uo (Uo is low voltage system to null line voltage)
