【推荐2】If you walk through the doors of one of the Smithsonian Institution’s museums in Washington, D.C., you may be greeted by an unusual guide. A Japanese tech company recently sent 25 humanoid robots to the Smithsonian. All of them are named Pepper.
Each Pepper stands 4 feet tall and has a computer screen attached to its body. Built by SoftBank Robotics, the robots are programmed to share information about the museum in which they are based.
“Pepper is basically an experiment,” Goslins, director of the Smithsonian’s Arts and Industries Museum, said. “The idea is to explore and see how a robot performs in this kind of environment.”
Museum visitors communicating with Pepper. The robot can tell stories and answer basic questions. People even take pictures and dance with it.
“The robot draws big crowds,” said Allison Peck, director of marketing at the Hirshhorn. “People just love Pepper.”
According to the Smithsonian Institution’s website: “Pepper gives our museum workers a new way to reach and serve visitors.” For example, Pepper teaches Swahili words to visitors of the “World on the Horizon” exhibit at the Smithsonian’s National Museum of African Art.
Pepper also has the special ability to draw guests to less-visited areas of the Smithsonian’s museum. When Pepper is placed in a spot, crowds are attracted to that place.
When not educating museum visitors, Pepper stays in the Smithsonian offices, getting charged and programmed. After being charged, Pepper can run for about 8 hours at a time.
Pepper plays an important role, but the robot“ is not meant to take away human jobs at the museum, ” Goslins explained. “It is meant to give our visitors a more enjoyable experience while they are here with us.”

【推荐3】The Rise of Microchipping
On August 1, 2017, workers at Three Square Market, a company specializing in vending machines, lined up in the office cafeteria to be implanted with microchips. One after another, they held out a hand to a tattooist who pushed a rice-grain sized implant into the flesh between their thumb and forefinger. The group implant event, organized by company management, fitted into Three Square Market’s longer-term vision of a cashless payment system for their vending machines — workplace snacks purchased with a flick of the wrist. The televised “chipping party” was picked up by media outlets from Moscow to Sydney.
For Jowan Österlund, whose company Biohax provided the service, microchip implants were not radical or even novel. He has lived with one for years and has implanted hundreds of other young, tech-savvy (技术大咖) Swedes.
Microchip implants are essentially cylindrical (长圆形的) bar codes that, when scanned, transmit a unique signal through a layer of skin.
But Urs Gasser at Harvard University believes that extending beyond the Swedish tech-hub environment to a broader market will be legally and morally difficult. In his view, Three Square Market’s chipping event actually symbolizes the imbalances of power in the workplace. Are you a person being paid for your work, or are you the property of the company you work for?
Ifeoma Ajunwa at Cornell University adds that it is crucial to consider the implications of this technology in the context of increasing worker surveillance (管制).
A.Microchips will deepen this dynamic, as they “literally go with the worker whenever they go”. |
B.Chipping, thereby, has swept across the globe with its magnetic appeal. |
C.Not all of the attention was positive, however. |
D.Mostly, they have been used to organize warehouses or identify lost pets. |
E.Conquered by the “almighty” microchips, workers may no longer be their own masters. |
F.For this community, the chip signifies an all-in-one combination of biology and technology. |

【推荐3】Home fires can happen quickly, destroying lives and property, but unlike other disasters, most home fires can be prevented. Read on to learn 4 unexpected home fire dangers.
Having old smoke alarms
An effective smoke alarm can make much difference when it comes to surviving a house fire. It’s not enough to change the batteries twice a year, you also need to replace your alarms every decade. “You should test your smoke alarms every month,” says Lorraine Carli, vice president of the National Fire Protection Association. “But also don’t forget to check the dates and replace an alarm that is more than 10 years old.”
Leaving the kitchen while you cook
One in five Americans admitted leaving food cooking unattended on the stove, found an American Red Cross survey. Walking away from food cooking in the kitchen is a serious fire risk. “The leading cause of home fires is cooking, and the leading cause of those fires is unattended cooking,” says Carli. “If you need to use the stove or oven, be sure to keep an eye on it.”
Turning the heat too high when you cook
Turning up the heat too high can be deadly, even if you’re in the kitchen while you cook. Kevin Kelley, senior director of the American Red Cross, recommends paying close attention and turning off the burner if you see smoke or grease(油脂) starting to boil while frying food.

【推荐3】Mary Somerville was born in 1780 in Burntisland, Scotland. Her contribution to mathematics was in both algebra (代数) and differential and integral calculus (微积分学).
Mary was one of the world’s first famous female mathematicians. She became interested in mathematics and decided to study it at the time when it was considered unacceptable for a woman to do so. She bought books on algebra and geometry and read them at night. In spite of disapproval from people around her, she firmly went on with her struggle to learn. She won a prize for her solution to an algebra problem. She went on to write several books on mathematics. Later in her life, she thought deeply about the years in which she had persevered (坚持) almost without hope and said, “It taught me never to lose heart.”
Mary’s way of learning remains useful today. If she worked for a while on a problem without coming up with an idea, she stopped working and turned her attention to the piano, her needlework, or a walk outdoors. She then returned to the problem with a fresh mind and a solution turned up. If she could not understand a passage while reading, she would forget about it and read on; several pages later, the meaning of the puzzling passage would become clear to her.
