Since the founding of New China, scientists who have been studying abroad or living in exile have been returning to China to serve. No matter how well they have developed abroad or how generously they have been treated, they have never forgotten their homeland. In today's society, there are numerous such patriotic scientists, and the trend is to become younger.

In recent years, with the opening of the national "Talent Introduction Program", more and more foreign scientists have started to come to China, including a top scientist from Switzerland, Vetterich. He was the Secretary General of the International Union of Science, and during his tenure he helped China join this organization, the first time since the founding of New China that China joined an authoritative international scientific organization.

He is a member of the Steering Committee of the World Association of Leading Scientists, a member of the Académie française, and a foreign member of the American Academy of Scientists. Wittlich was awarded the Nobel Prize in Chemistry in 2002 for the discovery of the NMR technique for the determination of the three-dimensional structure of biological macromolecules in solution.

With this discovery, he has become a major player in the international biochemistry community, and he is a billionaire with a fortune of over $100 million. However, as a foreign scientist, he was granted a green card in China and was determined to develop in China. After he joined China, he not only made our country a world leader in the field of nuclear magnetic resonance.

He also led the Chinese team to study structural biology, making China also at the world advanced level in structural biology. Whether scientists who go abroad for development choose to return to their home countries to serve or foreign scientists take the initiative to join China, it is because of the strong cohesion and cultural inclusiveness of our nation.

So why did Vettelich help China join the ICSU? How did he get his green card to China? What contributions did he make to the development of science and technology in China after joining the country? Today we will take you to learn more about the legendary life of this Nobel Laureate Wittlich. Interested friends may wish to give me a nod plus attention, your recognition will be my greatest motivation.

Soccer Dreams Broken, Devoted to Research

Wittlich, born in 1938 in the Swiss town of Arlberg, a place of beautiful scenery and pleasant climate, and Arlberg is only twenty kilometers from Bern, the capital of Switzerland's cultural and commercial center.

Therefore, in addition to its pristine environment, the town of Arlberg also has a thriving cultural economy. As a child, Wittlich thrived on the nourishment of this world. Surrounded by this pristine atmosphere and modern culture, he developed a quick mind and a wealth of insight. He was often amazed at the wonders of nature and the remarkable capabilities of modern industry.

Wittlich's parents were high-ranking intellectuals who took their son's education very seriously without restricting his natural instincts. The rich external environment and the education of his parents gave him a great interest in natural sciences.

As a teenager, Wittlich loved to play soccer, and he became obsessed with the sport. The European countries were very fond of this sport and took it very seriously, with world tournaments such as the World Cup, the European Cup and the Champions League. They were very passionate about this sport and naturally, Vettelrich became a big fan of soccer.

At the age of 23, Wittlich entered Bernier University. During this time, the passion for soccer in Europe was at an all-time high, so he majored in physical education and enjoyed the feeling of running freely on the vast grass fields.

During his college years, Wittlich joined the school's soccer team and became a starter on it, often representing the school in various league activities. At one point this made him think that he would soon become a real soccer player and start his career.

But as often as not, the sky is the limit. After being knocked to the ground by a hard tackle from an opponent during a game, he fell to the ground and was rushed to the hospital. Doctors later diagnosed that his right ankle was severely fractured and he would never play strenuous sports again, including soccer, naturally.

The news was like a bolt from the blue for Wittlich, who could not accept the fact. Was soccer goodbye for good? Would he no longer be able to run on the green field, to sweat and to enjoy his victories? This series of facts came to his mind and crushed his heart, and he was very sad.

Anyway, the reality was in front of him, not to mention becoming a professional soccer player, even the most basic of playing soccer could not be done by himself. After a period of depression, Vettelrich slowly accepted this fact and came out of his self-confusion.

Life goes on and one must look forward. Wittlich knew he had to get back on his feet or his life would be ruined. Saying goodbye to soccer allowed him to focus more on his studies. Although his passion for soccer once overshadowed his studies in culture, Wittlich was never bad at it, especially in science, where he always ranked among the best in school.

He has always had a great interest in these natural sciences because of the environment and culture he was brought up in. So he focused on them, and since he couldn't be an athlete on the sports field, he became a researcher doing research, thought Wittlich in his mind. You have to have a goal in life to move forward with determination.

Enter the world of science

He was amazed to find that the world of chemistry was no less exciting than the fierce matches on the green field, and he felt the magic of the natural world.

After four years of quiet and fulfilling life at the University of Bern, Wittlich successfully obtained his bachelor's degree in chemistry. After graduating from university, he still felt that he was lacking in chemical research and decided to stay at the University of Bern to pursue a master's degree in chemistry.

He later received his master's degree in chemistry from Wittlich in 1962. It took only one year to illustrate his amazing talent for the study and research of chemistry. It was also destined that he would have a lifelong relationship with chemistry.

After graduating with his master's degree, Wittlich felt that he had reached a "bottleneck" in his chemistry studies at Bernier University, so he wanted to look elsewhere. On the recommendation of his graduate advisor, he chose the prestigious University of Basel. This is one of the oldest universities in Switzerland, with a reputation for biochemistry and psychology research, and a place among the world's leading universities.

With a solid foundation in chemistry theory and research, Wittlich successfully passed the entrance exams at the University of Basel. Here he continued to choose chemistry as his main research direction and pursued his PhD in chemistry.

During his doctoral studies, Wittig was guided by a number of distinguished faculty members and enjoyed the most privileged research environment, which provided him with a solid foundation for his future discoveries in the field of nuclear magnetic resonance.

The fact that Wittig received such a good education was due to the layout of scientific research in Switzerland in the 19th century. They introduced a large number of welfare policies for the best researchers, which not only made Swiss scientists enthusiastic about their research, but also attracted a large number of foreign scientists.

From here it is easy to see which country attaches great importance to the training and introduction of scientific talent. It is only because of the environment and national strength that these policies are implemented earlier or later. The "Hundred Talents Program" implemented in China in recent years is very different from the Swiss welfare policy for researchers.

In 1964, Wittig again obtained his PhD in chemistry from the University of Basel in just two years, thanks, of course, to the excellent research environment provided by the university and the careful supervision of several supervisors.

Afterwards, Wittlich stayed at the university as an academic in order to continue his research during his doctoral studies, as it had the best research environment in the world at that time. In addition to his research, he also gave lectures to the students of the university. Under his influence, the whole University of Basel became a chemical fever.

Many years of academic study, looking for research direction

Yet after years of painstaking study, Wittlich never found a clear direction for his research. Although chemistry was by this time a relatively mature science, there were gaps in many areas. Therefore, he thought of making his own way in a path that had not been taken before.

Wittlich is the kind of person who can be 100% committed to what he loves. He knew his goal at the moment and began to read and research without a second thought. He spent half of his day in the laboratory, often repeatedly corroborating the results of an experiment. When he returned to his home, he still had to consult a lot of books and materials, and rested only when he could not stay up.

Although most of the time it did not bear fruit, Vetterich still did not choose to give up. He still went to the cutting edge of science every day and did his research relentlessly. It was with this persistence that he gradually came into contact with the field of electron nuclear magnetic resonance, and he found that countries around the world were beginning to do some research in this field, which must be the mainstream of future scientific research.

As a result, Wittlich immediately set the field of nuclear magnetic resonance as his research direction. However, at that time there were hardly any scientists in Switzerland who were conducting research in this field, and it was unlikely that he would receive any help if he continued to stay at the University of Basel. In addition, Europe had just recovered from the gloom of the Second World War and was mainly recovering from economic production, without much energy for research.

The United States was not affected much by the war, and in recent years the United States has shown explosive development in science and technology, gradually growing into the world's top power. Research in the field of nuclear magnetic resonance (MRI) has also gained some ground here in the United States. Therefore, Wittlich wanted to go to the United States to try and see if he could find inspiration for research in this area.

Do you support Vettelich's trip to the United States for research "inspiration"? If so, please leave the word "I support" in the comment section or ask your friends to extend their fingers and give him more praise.

Before coming to the U.S., the University of Basel sent a letter of recommendation to the U.S. to allow their outstanding student to travel to the U.S. for exchange studies. Given the relationship, the U.S. readily agreed to the request. The University of California, Berkeley Chemistry extended an invitation to Wittlich.

In 1965, Wittlich brought his family to the University of California, Berkeley, USA for chemistry. This is where the world is currently at the forefront of research in the field of nuclear magnetic resonance. It was a place with more advanced research conditions than Switzerland and a large theoretical base, which made him feel more confident about his research.

Relax and dive into research

During this period, Wittlich's research in the field of MRI went a little deeper, and he traveled tirelessly from laboratory to laboratory every day, as if he had found his soul and did not feel tired or hard at all. Once he had a firm goal, he would go ahead, and this is the kind of person Vitrich is, who will persist in what he has decided to do, no matter how difficult it is.

After spending two years at Berkeley Chemistry, Wittlich made modest progress within the field of nuclear magnetic resonance, but nothing significant was ever achieved. This made him realize that scientific research is something that cannot be rushed, and that the only way to catch a glimpse of "inspiration" is to dive in and think about the subtle changes.

Therefore, Wittlich decided to return to Switzerland with his family and sink his teeth into his research in his native country. After returning to Switzerland, he was ready to form a research team, understanding that there is no limit to the power of one person. Such a large project requires a large amount of algorithmic data and multiple experimental results, which he could not do alone.

Moreover, the field of MRI is not a specialized field, but requires multidisciplinary and multidisciplinary talents to carry out cross-cutting research fusion in order to overcome the challenges in this field and thus achieve certain achievements, which shows the importance of teamwork in scientific research. He himself is no longer limited to chemistry research and has started to study in multiple disciplines.

In 1969, Wittig joined the ETH Zurich as a guest lecturer, teaching biological structure to students. Here he met two like-minded PhDs and the three decided to work together. As it turned out, the joint efforts of the three of them greatly accelerated the experimental process.

Scientific research is never done behind closed doors. It is only when everyone's ideas and perspectives merge and collide that unexpected results can be achieved. A few years later, Wittlich, who had been immersed in the field of nuclear magnetic resonance for a long time, tried to apply this technology to the field of polymers, developing agents that had an effect on certain proteases and amino acids.

After several trials, Wittlich and his team completed the full identification of a single spectral peak of a protein. The progress of this experiment was very exciting for Vetterich, and it was the most exciting moment in his years of study and research, as if he was just one step away from opening the door to the world of science, and he had to grasp to create more out of it.

After this, Vetterich and the researchers in the team got in the mood and went back to their intensive research. The excitement of impending success kept everyone motivated, and the lab became a "second home" for each researcher, no matter how hard they had to work.

Gold always shines

In 1984, Wittlich first used this technique to map the three-dimensional structure of a protein. His achievement caused an uproar in the international scientific community, with many scientists shocked by his amazing discovery and many questioning the results of his experiments.

Until then, the three-dimensional structure of proteins could only be resolved by X-ray crystallographic diffraction. This method is very difficult and inaccurate, so this new method is somewhat unbelievable. Wittlich's efficient and simple method overturns the traditional perception.

In 1988, at the suggestion of crystallography experts, Wittig was invited to participate in a series of control experiments, which showed that the three-dimensional structure obtained by X-ray crystallographic diffraction was essentially the same as that obtained by Wittig's group, but many people were still skeptical.

It was only in 1992 that his technique was slowly recognized by the international scientific community after a scientist used the X-ray crystallographic diffraction method to break down the three-dimensional protein structure of metallic sulfur in exact agreement with that derived by Wittlich's new method.

Years of dull scientific research and times of lack of recognition did not upset Vettelich's heart. Instead, he sank his heart into education, and he produced a large number of scientific and technological talents for Switzerland, and he never hid his knowledge when he passed it on. He was not only a scientist but also an excellent educator.

Wittlich's research process has never been interrupted, and he has never given up his research in the field of MRI no matter what the situation is. Even when he was not recognized, he knew in his heart what he was doing, so he felt that the recognition from the outside world was not that important.

As the saying goes, gold always shines, and in 1992, Wittlich's results were confirmed and he was widely recognized by international scientists. After many more years of research, Wittlich led his team to complete the research on this topic thoroughly, which took the entire international scientific community by storm.

Their final research results using nuclear magnetic resonance technology to achieve the three-dimensional structure of biological macromolecules in solution is known as a landmark development in the field of nuclear magnetic resonance, and the technology has a very significant significance in a number of fields, and has had a profound impact on future generations.

For this achievement, Wittlich was awarded the Nobel Prize in Chemistry in 2002, together with two scientists of the team, American and Japanese nationals. The discovery also brought him a huge fortune and made him a billionaire.

In addition to this honor, he is a member of the French Academy of Sciences, a foreign member of the American Academy of Sciences, and later a member of the Steering Committee of the World's Leading Scientists. All of these honors are due to his persistence. He worked on this project for forty years until it blossomed.

To know that such persistence is not simply talk, only people with great perseverance can do, because it requires us to spend one day and night, but also to face the process of doubt and difficulty, just ask how many people can do. Besides, life is only a hundred years, the spirit of doing one thing for forty years is really valuable.

Although Wittig's dedication to things is admirable and incomprehensible, he was not a scientist who did "dead learning". In addition to focusing on his own research, he was a member of several national academies of science, and he even focused on education, serving as a visiting lecturer at the Zurich Academy and as a professor at Scripps.

We have helped you to get the "China Green Card".

As early as 1975, Wittlich was invited to join the International Scientific Union. Throughout this time he has been active in promoting international science, often giving a helping hand to countries and people who are truly capable of entering the organization, never distinguishing between nationality and ethnicity, and never refusing anything that is truly beneficial to the development of the world.

After many years of outstanding work ability, Wittlich made it to the position of Secretary General of the Federation. And our country was one of the countries that he helped so much. With his voice, our country succeeded in joining this scientific organization, and since then there has been a place for China in the international scientific community.

In fact, as early as 1983, Wittlich came to China with his wife for a study tour, and he thought that China was a country with great potential, and the whole country's science and technology business was a thriving scene, and that the future China would definitely be the mainstay of the country's scientists.

This left a very good impression on him, and he had a very high opinion of China, which is why he was so helpful in the matter of China's joining the International Scientific Union later. With our country's leading position in the world of science today, one has to say that Wittig is a man with a long-term vision.

Since that year, Wittig has intensified his cooperation with China in the field of science education, and in 2013 he became a professor at the Shanghai University of Science and Technology, training a large number of people for China in the field of biological structures.

He also personally led his team to carry out close and in-depth exchanges and cooperation with China in many fields such as the field of nuclear magnetic resonance and biology, which has greatly driven the development of science and technology in China and allowed China to catch up with the world in the research of biological structures.

The Chinese green card is said to be the hardest green card in the world to obtain because once you get a Chinese green card it means being recognized by all of China. To be recognized by the whole of China, one must have made a great contribution to the country or played an important role in the economic and cultural process of China.

Vetterich is naturally one of the foreign scientists who received a Chinese green card, and he deservedly received this Chinese green card. his great contribution to our scientific research and talent education deserves every Chinese to remember this friend. in 2018, China officially granted Vetterich a Chinese green card for permanent residence in China.

With the economic and cultural take-off of our country in recent years, more and more foreign talents are attracted to our country. Want to join our country. This we are naturally happy to see, but also will not blindly accept, only then our country can develop better and better.
