Exploring the universe and sowing dreams?

On the occasion of the arrival of the 38th Teacher's Day, the advanced deeds of "the most beautiful teacher" in 2022 will be announced to the whole society.

This year, the "most beautiful teacher" specially selected Wang Yaping, a special astronaut of China Astronaut Center, as a special tribute. She held space classes for primary and secondary school students three times, sowing the seeds of dreams for young people! Let's listen to the wonderful story of Wang Yaping's two flying dreams and standing on the "space platform".

The dream of sowing seeds in space classroom

Astronaut Wang Yaping of China People's Liberation Army Astronaut Brigade

Three crew members of Shenzhou XIII demonstrated the "Olympic Games" under the condition of weightlessness in the universe.

The picture shows the flight crew of Shenzhou XIII.

At that moment, I seemed to hear the sound of flowers blooming.

I am Wang Yaping, astronaut of Shenzhou XIII manned mission group.

As a "universe teacher", I feel very satisfied and happy to stand on the "universe platform" for three times and share the fun and mystery of science with you.

The short time when I was connected with my classmates will become a very precious memory in my future life.

Becoming a teacher is my childhood dream.

I still remember that the Chinese teacher told us a vivid little story in primary school. The math teacher is a PE teacher that students like very much, interspersed with boring numbers in incredible fairy tales. Because she will take us to run and play on the school playground. ...

Good times are always fleeting. When we are playing, we grow up inadvertently.

In middle school, I came into contact with a little profound knowledge.

The teacher explained the profound knowledge of physical chemistry in a simple way.

At that time, it seemed that we could glimpse the mystery of science and discover the beauty of the universe from the law of simple pendulum and chemical reaction.

Seeing the teacher talking about Kan Kan on the platform, I sincerely envy him and dream that one day I can stand on the platform and convey what I have learned to the students without reservation.

Teachers, a sacred and beautiful profession, carry the function of spreading ideas and culture and play an important role as a bridge and link in the development of human society.

I have had this "teacher dream" for more than ten years.

After graduating from high school, I became a glorious air force pilot.

While flying in the blue sky, I am getting farther and farther away from the podium of my dreams.

Later, after layers of selection, I was selected into the China People's Liberation Army Astronaut Brigade.

Of course, it's not bad to be an astronaut and fly into space.

However, I vaguely feel that there is no such "teacher dream" in my life.

Who knows, fate waved to me again and gave me a chance to realize my dream.

In 20 13, after being selected into the Shenzhou-10 manned mission group, I was excited to learn that I could teach primary and secondary school students all over the country in space.

Becoming a teacher, this dream has finally come true! At that moment, I seemed to hear the sound of flowers blooming, and it seemed that the moon hit my heart, which was very clear and bright.

Imagine that. Before class, the students shouted "Good teacher" and "The teacher has worked hard" in immature voices. After class, the children raised their innocent faces and asked questions to "Teacher Wang" in succession ... These are the most anticipated and envied pictures when they were children.

My heart is like a boiling wave, waiting for the moment of dreaming.

On the other side of the lens are thousands of pairs of eyes eager for knowledge.

Everyone will have many firsts in his life. Their first time means unknowns and challenges, which will enlighten us more or less.

For those who have never been to the podium, the experience of being a teacher for the first time is still fresh in my memory.

Teaching in space is the first educational application task in the history of manned space flight in China, and it is also the first time in the history of manned space flight in China to carry out popular science education activities for the whole country and the whole world.

Mission, unprecedented glory; Responsibility is also unprecedented.

The Shenzhou-10 manned mission set out with such a sacred goal. My heart is full of excitement and expectation, and my heart is beating fast.

On June 20th, 20 13, the official universe teaching day finally arrived.

There are only three astronauts standing in the heavenly palace, facing only one lens, but I know that there are thousands of pairs of eyes eager for knowledge looking at me on the other side of the lens.

At that moment, I felt very sacred and proud.

I am proud to stand in front of thousands of primary and secondary school students!

The mission of that space class was very successful, and every experimental demonstration was a success.

You can clearly hear the students' surprised laughter from the headphones, and you can also hear the thunderous applause in class.

I think it's worthwhile to work hard and sweat at the moment when the dream comes true.

Because the children's laughter and applause in class is the best reward.

The first space class will be over soon. Immersed in the classroom, I have no meaning yet. The students also have an endless aftertaste.

The child seems to be listening. "Is there anything else? Anything else? I still want to see it. The universe is incredible ... "

The title of "Teacher Wang" is my greatest achievement in completing the Shenzhou-10 manned mission.

As a teacher, I feel sincerely happy and happy to plant space dreams in children's hearts and start their dream-chasing journey.

"Flying dreams are by no means weightless, and the tension of scientific dreams is infinite.

"This sentence is deeply rooted in the hearts of every student.

Perhaps I am surprised by my "infinite strength", perhaps I am curious about the measurement quality of Newton's law, perhaps I am attracted by the infinite tension of water obtained by water film experiments, perhaps I am attracted by the gyro spinning at high speed in space ... The first space science education activity has made many primary and secondary school students yearn for space and learn scientific and technological knowledge.

Now, some children at that time entered the university and embarked on the society.

Some of them keep their love for the universe, and some are growing into members of the front line of the universe.

On 20 19, Wang Nan, a graduate student of Beihang University, wrote to me.

As the first "aerospace class" student who took an aerospace class that year, she chose aerospace-related majors after the college entrance examination.

She said in the letter: "You may not know who I am, but you have long been the light I yearn for on the road to pursuing my dreams.

Later, Wang Nan graduated from graduate school and became an astronaut ... Wang Nan's dream-chasing story is just a microcosm, and there are many children who love space and devote themselves to the space industry like her.

I also want to thank Mr. Barbara Morgan, the world's first "teacher of the universe".

As the teacher of the first space class in China and the second space class in the world, I received a letter from her on the eve of class.

In the letter, she expressed her greetings and wishes to us, and gave warm expectations and encouragement to the space class.

The first space lecture was a complete success and was praised by the media. "Lightweight space classroom not only shows the scientific and technological strength of China, but also shows the wisdom and humor of China people, sowing the fire to explore the future.

"

Through their clear eyes, I saw the stars all over the sky.

The universe is not only the place where every child is fascinated, but also the direction in which every astronaut has been running.

Time has passed, and it has been nine years since the first space class.

For nine years, I have been keen on popular science and love everything related to space science.

Like the students, I keep learning, settling and accumulating, and look forward to joining the space class with the students again.

Space class has brought me many achievements. It has created a deep teacher-student relationship between me and my children, and it has also given me the opportunity to communicate with them face to face after returning to the ground.

From the innocent and lovely eyes, I feel the children's longing for the universe and the desire for the unknown world; From their whimsy, I found that children's imagination is infinite.

An educator said: "The greatest progress of science is brought by new bold imagination.

"Children's imagination, isn't it the hope of the future development of science and technology in the motherland?

I often wonder what makes me so fascinated by the name "teacher of the universe". What makes you miss the popular science of the universe infinitely? Slowly, I found the answer. It was a mysterious and beautiful Family of the universe, a scientific dream with infinite tension, and the eyes of a child eager for knowledge.

Through their clear eyes, I clearly saw the beautiful universe and countless stars.

After being selected into the Shenzhou 13 manned mission group, I will continue to teach children space knowledge according to the mission arrangement.

My mood is not as calm as before;

-Very excited. Because I can also know the children in the universe as a "teacher of the universe".

Unfortunately, in this class, the first space class, they have "wronged their children for several years." Will they lose contact with the new space class?

Good luck. Because this space class can make more children understand the universe, know the universe and discover the charm of science.

-Looking forward to more. I hope this course can make more children love the universe, approach the universe, let us know about the popular science of the universe and meet in the cause of the universe.

The second time I boarded the platform of the universe, I felt more confident and calm.

Through the screen, staring at the children's eyes eager for knowledge, I am full of power.

I always feel that in this love between teachers and students, I enjoy and benefit the most-for these children, I am still the same as I was when I was young; Because these children, no matter how hard and tired I am, feel that there is a warm force supporting me; Because of these children, I hope every day in the future will be as happy as it is now.

My dream came true again, and I realized my better self.

Compared with the past, there have been more changes in "hardware" and "software" in space teaching on China Space Station.

The course of the space station is different from that of Tiangong-1 in many places. In the class of Tiangong No.1, I can only hear the sound from the ground class. In the class of the space station, I can not only see the sound on the ground, but also see clear images.

As a "teacher of the universe", I am also changing.

Benefiting from the precipitation of time and the accumulation of knowledge, I feel more satisfied in the new universe classroom.

On the afternoon of June, 5438+February, 9, 2023, Ye Guangfu and the water film tension experiment were displayed with small paper flowers in the universe classroom.

The little pink paper flowers on the water polo were folded on the ground by my daughter and me.

That flower bloomed so beautifully in the experiment, just like my daughter's bright future.

In September 2022, she will usher in a new stage of her primary school life.

I want to ask my daughter about that beautiful flower. There are many beautiful flowers waiting for her to discover on her way to school in the future. I also want to tell all young friends through blooming flowers that as long as I sow my dreams, I will definitely get hope.

Science is romantic and magical.

The beauty of science is unforgettable. It depends on whether you have a good time.

The beauty of the universe lies in that it can show the invisible scenes on the earth and reveal the scientific mysteries that cannot be revealed on the earth.

For example, "water polo becomes ice", water and oil are inseparable with the constant pulling of the liquid bridge.

Everyone knows these seemingly simple physical and chemical phenomena, but it takes a lot of brains to demonstrate them well.

For example, in the space ice and snow experiment, students see a perfect picture in class. Water polo floats in space. I gently put the hair root in my hand, and the water polo instantly froze and became a hot "ice hockey".

This is a common crystallization phenomenon in the chemical field. The supersaturated sodium acetate solution is very unstable at room temperature, and fine dust may induce crystallization.

However, it is very difficult to perfectly express the incredible effect of "water turns into ice".

You may not know that this popular and magical experiment "died" halfway.

During the exercise, many things happened. First, carrying less supersaturated sodium acetate solution, the task load is almost harsh to gram level, and there is little opportunity for exercise. Second, when we first demonstrated this experiment in space, anything unexpected could happen.

In order to complete the experiment of "Snow Queen", we cooperated with Tiandi and made several plans.

However, several exercises failed.

When everyone was about to give up, I continued to complete the experiment with the perseverance of "not dying until I reach the Yellow River" and made preparations for all possible special circumstances in advance.

On the afternoon of March 23, 2022, as the earliest experiment of cosmic ice and snow in the "Tiangong Classroom", it crystallized ahead of time, and we were helpless.

We took our time and calmly solved the problem and fixed it immediately.

Finally, we let thousands of primary and middle school students in front of the screen successfully watch the space premiere of Frozen.

It not only shows interesting physical and chemical phenomena, but also embeds national traditional culture and Olympic spirit.

Tie-dyeing is one of the textile dyeing technologies with a long history in China.

The unique display of dyeing products makes this precious intangible cultural heritage go abroad and fly into space.

We are particularly proud that traditional culture and modern science and technology are perfectly integrated in our hands.

The finished products we made are amazing, and the dyed works are elegant and pure, fresh and natural.

The combination of blue and white is also similar to the color of the earth in the universe.

As a part of "Welcome the Olympics from Heaven to Earth", I created the "Olympics" by chemical reaction.

The raw materials are not complicated. Add transparent plates embedded with the Olympic Games, three colorless solutions, three acid-base indicators and other solutions.

Under our operation, the colors of blue, black, red, yellow, green and "Olympic Games" are presented perfectly in turn.

Under the condition of weightlessness in space, the "Olympic Games" can float freely, and you can feel the deep breath in winter on the China Space Station.

The Olympic spirit of "higher, faster and stronger" coincides with the spiritual quality of our astronauts' unremitting struggle.

Space class not only vividly restores the physical and chemical knowledge in textbooks, but also incorporates many factors such as culture, art and sports.

The success of the space course contains a truth: the power of scientific knowledge and the power of beauty are always around us. As long as we have a dual vision of exploration and our hearts are full of longing for the future, we can find this power.

Just like the song "Running" sings: "There are dreams, wings flapping by wind and rain, and courage to go forward ... even a small sailboat can go far ..."

In our long journey of life, as long as we are diligent, we can do whatever we want and do whatever we want.

The beauty of science may be here.

The dream continues, let's meet in the future.

20/kloc-in June, 2003, 80,000 schools and more than 60 million students in China watched the first issue of Tiangong Classroom at the same time. From June, 5438 to February, 2023, the first class of China Space Station was held. In less than one day, the number of clicks on related reports on the Internet reached 2 1. 1 billion, and more and more people paid attention to our space class. In March, 2022, Class Two of China Space Station read more than 654.38 billion times on Weibo-related topics, which was called "Popular Science Space Edition, live broadcast from the ceiling" by netizens.

After space class, I received many letters from children.

"Teacher Wang, you gave me a dream. Like a caterpillar, slowly climb to the top of the tree.

One day, I will climb up, become a butterfly like you, fly into space and realize my dream.

"

"Teacher Wang, I must study hard, become an astronaut in the future, explore the wonderful universe and become a useful person to mankind and the country.

"

"I know that flying in the air is not easy to achieve. It means that astronauts can only create wings flying in the sky by enduring difficulties for a long time and unremitting training ... "

Space class is like a silent spring rain, which has dyed the earth red and moistened the eyes of countless children.

Space class is like a warm spring breeze, gently blowing in the fields.

Countless dandelions in full bloom, holding small white umbrellas, are like seeds of space dreams, dancing lightly with the wind and flying to the sky of hope.

No matter where it falls, the seeds will take root and sprout, and beautiful dandelions will bloom in the coming year.

Space teaching activities have left an indelible impression on many students, and the future will accompany them all their lives.

I was also baptized by scientific knowledge when preparing lessons.

Space exploration is endless, and more wonderful scientific knowledge needs to be discovered.

The bell of the universe classroom rang, and I returned to the earth, but the transmission of scientific knowledge continued forever.

There is a soul in the heart and a star in the hand.

Everything is unknown and worth exploring.

All restrictions can be exceeded.

I expect the majority of students to set up young Ling Yunzhi and become down-to-earth people in their future studies.

The space class planted dreams for my classmates and pointed out the direction for my future struggle.

In manned space flight and popular science education, I will try my best to integrate popular science education with the space industry and always be the "space teacher" in the hearts of children.

Of course, the great success and influence of space teaching can not be separated from the efforts of every astronaut in the new recruits.

I remember the first space class, Nie Haisheng Chang and photographer Zhang and I were in tears, and our hands were tightly held together.

We are excited, emotional and excited about the successful completion of such a big task.

During this space station mission, Commander Zhai Zhigang and astronaut Ye Guangfu cooperated with me many times and got very tacit cooperation. Two space courses were successfully concluded, each showing its own style.

The content of our aerospace course is getting richer and richer, which cannot be separated from the strong support of the ground support team.

From curriculum setting to script writing, discussion and exercise, scientific research support personnel have made great efforts.

In order to complete the space science popularization activities, Huang, the chief designer of the astronaut system, had a whim.

The heavy work and a lot of communication in the early stage made her throat sore and speechless.

Nevertheless, she continued to examine the details of the universe carefully.

Manned space flight is a systematic project, and so is space teaching. Collective wisdom and strength must be brought into play.

Although the time of space teaching is limited, its spiritual connotation of radiation and reflection is infinite.

I hope more big friends and children can cultivate the spirit of unity and cooperation in their future study and work, give full play to team strength, benefit everyone, stand higher, see farther and walk more steadily.

In the next space station mission, popular science education activities will be carried out in depth through building popular science education bases, recruiting primary and secondary schools to carry experiments, astronaut orbit lectures, and exchanges between heaven and earth.

I believe that through our joint efforts, more people will get close to the universe and love it.

I believe that with the improvement of the experimental platform of China Space Station, the future space class will be more exciting.

We have an appointment for the next class, so be there or be square!

"Cosmic Teacher" Wang Yaping demonstrated the experiment of "Cosmic Happy Ball".
