In recent years, the Hong Kong Government has allocated more resources to attract citizens to participate in scientific research. But for Zhang Dajian, a 73-year-old visiting professor in the Department of Physics, the pursuit of learning and the courage to take the initiative to research is actually more important. Zhang Dajian is one of the people who joined the scientific research community with government funding. He founded the science and technology company "Booguu Company". One of the inventions of the "portable gait analyzer" is expected to be widely used in medical institutions in Hong Kong next year. Use to assess the risk of elderly falls.

Zhang Dajian himself is mainly academic research, such as studying wave energy, but when he returned to Hong Kong to visit relatives a few years ago, he suddenly thought about it and started "land-attached" research. He won prizes in the international and Greater Bay Area invention competitions for several years. . He has encouraged young people to seize opportunities and delve into things they think they can and can accomplish in the past six months.

Zhang Dajian's research on the minibus' "pulse" and "portable gait analyzer" both won awards at this year's "Asian Invention Exhibition-Hong Kong". During his visit, he did not mention that his papers published in the past decades have been repeatedly recognized internationally, and some of his studies have been patented. He did not share his own award winning at the well-known Geneva International Invention Exhibition two years ago, but instead shared his reasons for switching the runway halfway.

I came to Hong Kong from the 1960s to study in the United States as a scholar

He said that education was not universal more than 60 years ago. He was born in Suzhou in the Mainland and came to study in Hong Kong in the mid-1960s. At that time, he did not understand English. Study in the United States, become a scholar, and then bury a variety of research projects.

Before returning to Hong Kong to accompany his father, he looked back on his decades of research career, and concentrated on academic research, such as ocean wave energy, magnet power generation, and space instruments. He felt that research had little impact on the general public and did not want to leave regrets. Therefore, he re-started in his sixties to carry out research that is not related to previous research, and "practice land". He joked that his memory is better than before, and his current goal is to complete the research on "portable gait analyzers": "Starting from the first day and participating until completion!"

Looking back, I used to stop at a certain stage, but this time is an opportunity, there can be all the way, so that I don't want to do it, I told my wife that it will take another ten years!

It was thought that Zhang Dajian lived to the old age but did not have the heart. After retiring, he had the courage to start a science and technology company and carry out untouched research fields, which was influenced by the American academic atmosphere. But he said his father was the key figure. It turned out that his father never forced his children to review. He just loved to ask questions to allow their children to explore and explore freely, and to train them to study and research on their own. He was grateful for his father ’s teaching, and described his father ’s learning attitude as having deeply affected him: “Father ’s method is different from traditional Chinese education. I guess there are some genetic influences. I ’m also curious. I want to study and think about everything. know!"

The second brother is the "rental king" and the older brother is a banker

Speaking of brothers and sisters, he shared with a smile, and the habit of getting together for common sense questions and questions about writings has remained unchanged for decades: "The Water Margin says that characters, flower names, and stories, whoever can't keep up, lose! They are very Yes, the second brother is Zhang Dapeng (the well-known stock and property investor "Mobil Lease King"), the third brother Zhang Da is a Singaporean banker, the fifth brother Zhang Dahai and I do research in the United States, everyone sister Zhang Dayu is For business, now she often calls me to dress in cold weather, haha!

Speaking of brothers and sisters, he shared with a smile, the habit of gathering common sense questions and answers has remained unchanged for decades: "They are very good now, the second brother is Zhang Dapeng (the well-known stock and property investor" Mobil Rent King "), The third brother, Zhang Da, is a banker in Singapore. The fifth brother, Zhang Dahai, is doing research in the United States with me. Everyone, Zhang Dayu, is in business. Now she seems to be a mother. She often calls me to dress in cold weather, haha. !! "

As for hobbies? He said that he loved origami, and even made a piece of paper on the spot that knew how to "make a fight," and invited reporters and public relations to cooperate to create a flying saucer with double stars. He described as having more than sixty years of experience in origami. Origami is entertainment and a good way to train his brain. At first, he read books and practiced. Then he thought about how to fold out different objects. He showed a three-dimensional fold out of HK $ 20. Rabbit said, "I want to give a child born in the Year of the Rabbit a few years ago. After thinking about it for a few hours, he successfully folds the rabbit for the second time!" Now living in the United States, he prefers to plant with his grandchildren. Sharing physics and math concepts with games, "Treasure hunting and playing games in the garden is better than watching TV!"

Anti-revision storms lasted more than half a year, and social and economic instability. Zhang Dajian bluntly felt sorry for the current situation, but encouraged young people to seize opportunities and delve into things that they thought they were able to accomplish: "The opportunities are everywhere, everyone will have Opportunity depends on whether you can seize it or not.
