They asked Katherine Johnson for the moon, and she gave it to them. With little more than a pencil, a ruler and one of the finest mathematical minds in the country, Mrs. Johnson, who died at 101 on Monday, calculated (计算) the track that would let Apollo 11 land on the moon in 1969 and, after Neil Armstrong's history—making moonwalk, let it return to Earth.
Yet throughout Mrs. Johnson's 33 years in NASA and for decades afterwards, almost no one knew her name.
Mrs. Johnson was one of several hundred strictly educated, extremely capable yet largely unrecognized women who, well before the modern feminist (女权) movement, worked as NASA mathematicians. But it was not only her sex that kept her long unsung. For some years at mid-century, the black women were forced to a double segregation (隔离). They were kept separate from the much large group of white women who in turn were segregated from the mathematicians and engineers.
Mrs. Johnson broke barriers at NASA. In old age, Mrs. Johnson became the most celebrated of black women who served as mathematicians for the space agency. Their story was told in the 2016 Hollywood film “Hidden Figures,” which was nominated (提名) for three Oscars, including Best Picture.
In 2017, NASA devoted a building in her honor. That year, The Washington Post described her as “the most celebrated of the computers” — “computers” being the term originally used to describe Mrs. Johnson and her colleagues, much as “typewriters” were used in the 19th century to represent professional typists.
She “helped our nation enlarge the frontiers of space,” NASA's administrator, Jim Bridenstine, said in a statement on Monday, “even as she made huge steps that also opened doors for women and people of color in the universal human effort to explore space.”
As Mrs. Johnson herself was fond of saying, her term at Langley — from 1953 until her retirement in 1986 — was “a time when computers wore skirts."

【推荐1】Weeds (野草) compete for soil nutrients, water, space, and sunlight with the crops farmers grow to help feed people. Now a third-generation weeding robot, armed with lasers (激光) and powered by AI, offers a labor-saving (节省劳力的) device — while also avoiding the need for chemical herbicides (除草剂) .
The Autonomous Weeder by Carbon Robotics can clear 100,000 weeds per hour, and clear 15-20 acres in a single day — numbers that require a person working an entire season to match.
Moving along a row of crops, a battery of twelve cameras scans the ground, identifying weeds through machine-learning and killing them with a CO2 laser. The robot's onboard supercomputer ensures high accuracy with its laser so as to avoid accidentally cutting crops.
“This is one of the most innovative and valuable technologies that I've seen as a farmer,” said James Johnson of Carzalia Farm in a statement, who has used Carbon Robotics' technology on his farm. “I expect the robots to go mainstream because of how effectively they address some of farming's most critical issues, including the overuse of chemicals, process efficiency, and labor. The sky's the limit.”
If a farmer wants to avoid using chemical herbicides, which have flooded nearly every corner of our food and water supply chains with a probable carcinogen (致癌物) , they must find enough unskilled workers to pull weeds manually — a difficult task in the already short market of agricultural labor.
Since it can solve both problems, it's no surprise that the 2021 model of the Autonomous Weeder has already sold out, even considering it is priced at hundreds of “thousands of dollars.”
To make the device more accessible, rent options are available from the company, as they have already made the 2022 models available for preorder.
The weeding method of the robot is organic and in line with sustainable farming practices. Cost-effective weed control is the biggest difficulty of organic farming, and agriculturalists looking to make the change finally have an option to help them get their vegetables out to people.

【推荐2】You’ve probably heard about how Sweden is running out of garbage. And it’s true: The country of just 10 million people sends less than 1 percent of its waste to areas of land where waste is buried under the earth. The waste is burned to create electricity and energy to heat homes.
Recycling is such a part of the culture that there’s even a shopping centre — the ReTuna — that has only upcycled (升级改造的) and repaired things. The shopping centre lies about 60 miles outside Stockholm in the town of Eskilstuna. There are 14 stores, a restaurant and also a program where interested Swedes can learn how to recycle even more.
The shopping centre was created as part of the local recycling center and includes a drop-off center, so locals can drop off things they no longer need or which need fixing, and pick up things they need — all without ever buying new things.
Not only are the people of Eskilstuna recycling more and wasting fewer materials, the center has offered the types of jobs including repair work, management of the shopping centre, selling goods in the shops, as well as roles for artists, and teachers (for the classes in repair and upcycling).
Looking at this project, we can start to see how waste doesn’t have to be a trouble or something we pay to deal with. Instead, we can use circular-economy (循环经济) thinking to deal with waste. Rather than the model of take-use-throwaway, the circular-economy model is one where everything we make is part of a circle of resources and energy, just like how the natural world works.
There’s great value in our garbage, if only we choose to see it that way. The shopping centre of Eskilstuna already does.

【推荐1】Society has certain standards for beauty. But Romanian photographer Mihaela Noroc, who spent nearly four years shooting portraits of women from around the world, is challenging these standards.
She believes that beauty can take on many forms. “Beauty just means being yourself,” Noroc told NPR. “I don’t think we have to change ourselves to be in a certain way; I think, we just have to keep ourselves as we are and don’t necessarily need to change.”
Inspired by a trip to Africa in 2013, Noroc has traveled to more than 50 countries and regions since then. In 2017, she compiled a book called The Atlas of Beauty:Women of the World in 500 Portraits to show how many different kinds of beauty there are in the world. A new edition of her book has recently caused heated discussion on social media.
From a struggling Russian dancer to a talkative cafe owner in New York, Noroc’s subjects engaged her in deep conversation. Noroc found out what moves them, what their daily struggles and joys are, and what brings beauty into their own lives. “No matter where I go, it’s the women that carry all the culture and traditions of a place. I really try to focus on women’s stories, how they face challenges and overcome them,” Noroc told CNN.
Her encounter with Ala, a student at a self-defense school in Jordan called “She Fighter,” left a lasting impression on her. Ala raises her clenched fists (握紧的拳头) as she looks into the camera while her face is covered by a whitehiab (穆斯林妇女戴的面纱). Noroc describes She Fighter as “the first self-defense school for women in the Arab world,” and writes, “I discovered an amazing initiative and a splendid sisterhood.”
In Iran, Noroc met Norocmet Farnoush, a woman who lives in two worlds. “In one she is an economist, by profession. In the other, she is an artist, because this is her passion.” For Noroc, the women’s beauty lies in how natural and comfortable they appear while just being themselves.

【推荐2】Red Adair became “the man to call” if you wanted a fire in an oil well to be put out, a task that was extremely dangerous and difficult. Red Adair was born in Houston, Texas in 1915. He got such a name because of his bright red hair. The color became a trademark for him. He wore red clothes and red boots. He drove a red car, and he and his men used red trucks and red equipment.
One of Red Adair’s most dangerous jobs was in 1962. He and his men put out a natural gas fire in the Sahara Desert in Algeria. Burning for six months, the fire was so fierce that American astronaut John Glenn could see it from space as he orbited Earth and the sand around the fire had melted into glass from the extreme heat. The famous fire was called the “Devil’s Cigarette Lighter”.
Adair’s success with the big fire and earlier well fires captured imagination of the American film industry. In 1968, Hollywood made an action film called “Hellfighters” which was roughly based on events in Red Adair’s life. Adair said one of the best honors in the world was to have John Wayne play him in a movie. In 1998, Adair troubleshot (排除故障)what was possibly the world’s worst ocean accident at the Piper Alpha oil platform in the North Sea. One hundred and sixty-seven men were killed when the oil rig(油井钻探设备)exploded after a gas leak. Not only did Red Adair and his team have to put out the fires but they also had to deal with winds blowing at more than one hundred and twenty kilometers an hour, as well as the sea which was at least twenty meters deep.
In March of 1991, Red Adair went to Kuwait to put out at even hundred Kuwaiti fires following the Persian Gulf War. His efforts saved millions of liters of oil. Some experts say the operation also helped prevent an environmental tragedy.
Red Adair died at 89 on 7 August 2004. Many Americans remember him as a very brave man. He lived his life troubleshooting danger. He was known for risking his own life to save others.
