3 . A university lecturer in Linyi, Shandong province, has shone a light on the difficulties of food delivery drivers by taking on the role himself for a month and sharing his trials and sufferings online.
Last December, Xing Bin, a lecturer at the College of Literature at Linyi University, was so eager to know about what life and work must be like for a delivery driver, so he decided to sign up and be one from December to January this year. The gig economy (临时工), for better or worse, has exploded in China in recent years, and though many members of the workforce choose to work in the gig economy because of its flexibility (灵活性), others prefer full-time employment.
During the month, Xing worked more than 10 hours and took 30,000 steps a day. He lost 6 kilograms and earned a total of 7,000 yuan. On average, he earned 10 yuan each hour, and 20 yuan at most. “ I was delivering food from early morning till late at night for around 13 hours a day. When I had classes, I delivered food for two hours early in the morning, and after dinner I continued delivering until one or two in the morning,” Xing said.
“Before, if I got a call from a delivery worker, I might delay answering it. But now I will always answer it immediately because I know they might be riding an electric bike while making the call, which is very dangerous,” said Xing, adding that he now understands the difficulties of delivery workers better and realizes how hard they work to make a living.
“During that month, I tasted the bitterness and the happiness of this job with my heart. I delivered over 2,000 orders, and three of the people who ordered impressed me a lot.” he said.

5 . Blind people have long desired for brightness, but scientists don’t have the technology. To bring that one step closer to reality, Zhiyong Fan, a materials scientist of the Hong Kong University of Science and Technology, developed a new artificial eye recently. The device, which is about as sensitive to light and has sharper vision and a faster reaction time than a real eyeball, may outperform human eyes.
The human eye owes its wide field of view and clear eyesight to the retina (视网膜) — an area at the back of the eyeball covered in light-detecting cells. The design for a new artificial eye is based on the structure of the human eye and uses a friendly light-sensitive material. At the back of the eyeball, an artificial retina is lined with Nan scale light sensors (纳米级光感器). Those sensors measure light that passes through the lens (晶状体) at the front of the eye. Wires attached to the back of the retina send signals from those sensors to the processor, similar to the way nerve networks connect the eyeball to the brain.
“In the future, we can use this to replace damaged human eyes,” says the lead designer. In theory, this artificial eye could see more clearly than the human eye, because the artificial retina contains about 460 million light sensors per square centimeter while a real retina has about 10 million light-detecting cells per square centimeter. Besides, the artificial eyeball records changes in lighting faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds. Although its 100-degree field of view isn’t as broad as the150 degrees a human eye can take in, the device can see as well as the human eye in poor light.
Hongrui Jiang, an electrical engineer at the University of Wisconsin, though, thinks engineers need a much more practical and efficient way to produce vast series of tiny wires on the back of the artificial eyeball to give it superhuman sight, which is super hard to achieve.

While some critics claim that history curricula (课程) teach unnecessary content, others argue that these curricula need to be more comprehensive. Despite ongoing debates about content, one universal truth remains: strong history curricula are necessary for developing the productive citizens of tomorrow.
The greatest academic value that history curricula provide is not the recall of important dates and names. Rather, understanding the historical inquiry process is the most important component. This process teaches students how to become critical thinkers and understand the dynamic nature of the telling of history.
Through strong history curricula, students are shown both a variety of primary and secondary sources and are taught to critique them. This is where the historical inquiry process begins. Students not only begin to analyze and ask questions about the content, but they also learn about the author’s credibility and potential bias (偏见). Students are then able to contextualize the information they learn and can think more critically about historical con text and those who tell it.
With this framework, students can then understand the causal relationship between human nature, values, philosophy, actions, and their consequences. It teaches students to recognize recurrent themes and lessons that are necessary to understand modern society. Most importantly, it teaches students to develop a healthy skepticism (怀疑论) when presented with information today because our actions are history in the making.
Forty years ago, renowned scholar James Fitzgerald argued that no education is complete without the teaching of historical inquiry. He believed that the only way to move forward in life is to understand what’s behind us.
Today, this principle still holds true. Students take both the factual knowledge and the historical inquiry skills they learn in the classroom and apply them to real world circumstances. Throughout their lives, students who are taught with strong history curricula will take the lessons they learn from our predecessors and become involved, active, productive citizens who want to create a history that tomorrow’s students will be proud to learn about.
