4 . Who has no regrets about things done in the past? Wouldn’t it be nice if, somehow, we could go back to change a couple of bad decisions? This sounds like science fiction.
The laws of physics prohibit traveling back in time for many reasons. If we did travel back in time and changed the course of events, we would be altering the course of history. An example often cited is the grandfather’s paradox (悖论): If your grandfather died when he was still a high school student, he wouldn’t have met your grandmother and your father and you wouldn’t exist.
Putting humans or consciousness traveling back in time aside for the moment, is there anything in science even similar? Surprisingly, yes. At the level of quantum particles (量子粒子), there is something called Wheeler’s delayed-choice experiments that show that actions in the present can influence the past. The experiments use something called the wave-particle duality (波粒二象性) of light and of matter. The fact that the physical nature of quantum objects is undetermined until it is measured. In other words, this means that a particle of light or of matter can behave either as a wave (spreading out in space) or as a particle (staying together) depending on the measuring devices. Long and ongoing discussions about the nature of quantum physics are still trying to work out what this actually means. Do our minds determine the nature of physical reality?
Should we offer food for thought for the future or the past? Unfortunately, these experiments say very little about how we could interfere with the past in events relevant to the human scale. Better to think carefully about decisions than to try to fix them backwards.

A.Is changing the past wise? |
B.Can we change the past? |

7 . Children’s Sci-fi Art Predicts Extraordinary Future
More than 80 sci-fi artworks are on display at the Shanghai Science and Technology Museum, showing a beautiful yet puzzling future. The “Brave New Sci-Fi World” exhibition features paintings and art installations (设备) by students from Shanghai, Beijing, Chongqing and other cities. They imagine the future as a world where robots and human beings co-exist.
Ru Chen, from Shanghai New Putuo Primary School, has pictured a robot chameleon (变色龙) to be used in outer space to aid in the search and rescue of human beings in case of danger.
Li Jiaqi from Guangzhou Dongfeng East Road Primary School has painted a city where advanced technologies are everywhere, and even the city itself turns into a large robot.
Huang Yanrui from Beijing Shijingshan Gucheng No. 2 Primary School imagines his rubber, pencil box and such stationery (文具) becoming conscious robots, and beginning to design future human beings.
Wang Zhihan, from Shanghai Shangde Experimental School and her schoolmates, stick electronic components on stone faces as a metaphor (隐喻) for the increasingly unclear boundaries between the reality and virtual world. “We hope to remind people never lose yourself in a world with advanced technologies,” she said.
The exhibition will last till November 4.
Opening hours:
Tuesdays-Sundays 9: 00- 17: 15; legal holidays 8: 45- 18: 30.
Transportation Guide:
Metro: Metro Line 2: Shanghai Science and Technology Museum Station.
Metro Line 4, Metro Line 6 and Metro Line 9: change to Metro Line 2 at the Century Avenue Station.
Bus Routes: Bus 184, 640, 794, 983, 984, 987, 1023, 640 inter-zonal bus will take you there.

Science fiction
The Three-Body Problem begins with the stories of two unrelated people, Ye Wenjie and Wang Miao. Ye is recruited to join
9 . When I was a boy growing up in New Jersey in the 1960s, we had a milkman delivering milk to our doorstep. His name was Mr. Basille. He wore a white cap and drove a white truck. As a 5-year-old boy, I couldn’t take my eyes off the coin changer fixed to his belt. He noticed this one day during a delivery and gave me a quarter out of his coin changer.
Of course, he delivered more than milk. There was cheese, eggs and so on. If we needed to change our order, my mother would pen a note — “Please add a bottle of buttermilk next delivery” — and place it in the box along with the empty bottles. And then, the buttermilk would magically (魔术般) appear.
All of this was about more than convenience. There existed a close relationship between families and their milkmen. Mr. Basille even had a key to our house, for those times when it was so cold outside that we put the box indoors, so that the milk wouldn’t freeze. And I remember Mr. Basille from time to time taking a break at our kitchen table, having a cup of tea and telling stories about his delivery.
There is sadly no home milk delivery today. Big companies allowed the production of cheaper milk, thus making it difficult for milkmen to compete. Besides, milk is for sale everywhere, and it may just not have been practical to have a delivery service.
Recently, an old milk box in the countryside I saw brought back my childhood memories. I took it home and planted it on the back porch (门廊) . Every so often my son’s friends will ask what it is. So I start telling stories of my boyhood, and of the milkman who brought us friendship along with his milk.

10 . My future happiness
When I imagine my future, I see myself as an adult who is confident in my abilities, doing a job I love and living my life responsibly. When I grow up, I will be enjoying more convenience brought by the advances in technology, with more time to pursue hobbies and enjoy the company of family and friends.
I will feel the happiest in the future because I will learn more about life and develop into the best person I can be.
Thanks to new technology, my future life is sure to improve in various ways. Homes will become smarter to the extent that they might be programmed to learn about our needs and monitor our health and activity. I can imagine hearing an AI voice remind me to buy groceries or do more exercise! There will also be enormous advancements in transport options. I will be riding in a self-driving car, and other new means of transport may be developed in the future.
My development into a mature adult and access to advanced technology will provide me with more free-time opportunities.
A.I might be able to ride a flying bike to quickly meet up with my friends. |
B.I will become more knowledgeable about the world and myself. |
C.When I think about the future, I realize my happiest days are still ahead of me. |
D.For these reasons, I look forward to the future as the happiest moment in my life. |
E.With less work-related stress, I will also have more time and energy to do volunteer projects. |
F.The working day will be only four hours long thanks to robots. |
