Attach! Riding the Wind and Waves Of Science and Technology 丨The first episode of dialogue with Zhai Wanming, academicians of the Chinese Academy of Sciences, and Zhang Jingzhong's "Only fast is not broken"

Sichuan online reporter Xiao Yingpei

In the long history of urban development, there is such a group of people who are doing their best to catch up with the forefront of science and technology, they are participants in the development of urban innovation, and they are also the most beautiful scientific and technological workers.

From the 23rd to the 24th of this month, the Ninth Congress of Chengdu Science and Technology Association will be held soon. From now on, the Chengdu Science and Technology Association launched the "Attack! Riding the Wind and Waves" series of theme videos and reports, using lenses and pens to record the mission and exploration of Chengdu science and technology workers on the road to building a city that fully embodies the new development concept.

In the first session, the dialogue focused on how to make the city's rail transit industry "run" faster and how to make Chengdu, a supercomputing city, "run" faster.

Attack! Ride the Wind and Waves Technologists" was launched

Zhai Wanming:

Promote collaborative innovation in schools and campuses

Playing the "Chengdu card" of rail transit well and doing a good job of "transformation road"

In a small office at Southwest Jiaotong University in Jiulidi, Chengdu, Zhai Wanming browses the world's latest rail transit "news" almost every day. In his view, always grasping cutting-edge information will bring greater opportunities for technological breakthroughs, and will also make him and the "railway" further.

The story of Zhai Wanming and the railway begins with an unforgettable "ride experience". In 1981, at the age of 18, Zhai Wanming was admitted to Southwest Jiaotong University, limited by the railway conditions at that time, from Jingjiang in Jiangsu to Emei, Sichuan, only 2,000 kilometers, Zhai Wanming spent three days and four nights to arrive at the school by train, during which she also stood for a day and a night. Such an experience made Zhai Wanming determined to find a way to apply what she had learned to the national rail transit development cause.

With the goal of building a "railway powerhouse", Zhai Wanming took Southwest Jiaotong University as the "base", continuously innovated in basic theoretical research, took the lead in proposing and systematically establishing a new theory of "vehicle-track coupling dynamics", and created a new field of railway system dynamics. At the same time, it also translates theory into practice, extending ground transportation to the sky.

In November 2016, the world's first new energy air-rail test line was successfully tested in Chengdu Shuangliu, which is also the first suspension train in China to innovate the energy-powered traction mode. "Chengdu's rail transit industry has a good foundation, universities, design institutes, engineering bureaus, rolling stock manufacturers are readily available, and the innovation industry chain is complete." At the same time, Chengdu is rich in talent resources and can provide sufficient intellectual guarantee. "Zhai Wanming believes that the air railway is the result of a joint research between industry, academia and research, which is inseparable from the mixed ownership reform of ownership of job scientific and technological achievements that Chengdu took the lead in carrying out in the country." Under the collaborative innovation of the school and the campus, more scientific and technological achievements can be transformed into productivity by incentivizing employee inventors to transform scientific and technological achievements with property rights. ”

Today, Zhai Wanming has been deeply engaged in the field of rail transit for more than 30 years, but the journey is far from over. According to the plan, the first new energy air-rail commercial line will be born in Chengdu, at present, the project is under steady construction, after completion will have both the air and rail industry demonstration function, the air rail test line function and tourism and tourism functions.

Zhang Jingzhong:

The "Supercalculant Man" in the "City of Supercomputing"

Find a way to get computers to implement human-like computing

When most young people's eyes are focused on the current hottest game - the league of legends playoff battle, Zhang Jingzhong, an academician of the Chinese Academy of Sciences who is more than 80 years old, is also deeply studying the new algorithms of mathematics in new scenes and new applications in "Mathematical Exploration".

From entering the Department of Mathematical Mechanics of Peking University in 1954 to becoming a famous mathematician and computer scientist in China today, Zhang Jingzhong has dealt with mathematics for most of his life.

During his 60-year teaching and scientific research career, Zhang Jingzhong proposed and implemented the numerical parallel method of machine proof of theorem, used the new method of geometry developed in the study of educational mathematics for many years for machine proof, and created the principle and method of automatic generation of readable proofs of geometric theorems. With this method, geometric proofs can be quickly carried out on microcomputers, new theorems can be calculated and invented, and easy-to-understand proofs of geometric significance can be given.

In recent years, with the continuous emergence of the effectiveness of educational mathematics and the great improvement of the effect of basic mathematics education, the focus of Zhang Jingzhong's work has gradually shifted to the automatic solution of mathematical problems. In his view, the use of computers to replace people for scientific research is long and difficult, but the future must be of great help to mankind.

In June this year, at the first Tianfu Forum on supercomputing innovation applications, Chengdu Supercomputing Center was released for the first time, and Chengdu Supercomputing Center is expected to achieve peak operation this year. The completion of the Chengdu Supercomputing Center, located in the core area of Luxi Zhigu in Chengdu Science City, will fill the layout gap of the national supercomputing system in the western region of China, and Chengdu ranks among the "supercomputing cities", and it is also this year that the Sichuan National Center for Applied Mathematics was officially inaugurated in Rong.

"The Sichuan National Center for Applied Mathematics was officially inaugurated, and although the project is still under construction, we can see that the influence and importance of mathematical scientific research are constantly improving." Zhang Jingzhong said that whether it is artificial intelligence or information technology, mathematics is the soul and the 'root system' of the towering tree. Many scientific and technological problems, in the final analysis, are algorithmic problems, and solving a problem is to find an algorithm. "The Sichuan National Center for Applied Mathematics has been continuously built and improved, bringing a better carrier for basic scientific research, and also providing a good environment for the combination of technological innovation and basic science." I hope that through the construction of these large platforms, mathematics will become a 'game' that young people love to play, so that mathematical research can play its due supporting role in scientific and technological innovation." ”
