It’s always nice to have a little help around the house. But what if you could employ the assistance of one of the greatest minds of the 20th century？
That’s the idea behind a new robot modeled after Albert Einstein. Called Professor Einstein and standing at just over a foot tall, this personal assistant can tell you the weather and keep track of your schedule like any other robots. With built-in Wi-Fi, Einstein robot has access to brain ceasing games, and can answer math problems and science questions. With natural language speech processing, you can actually interact with Professor Einstein. And because the robot is connected to the Internet, it is constantly updated with new information.
To help get the perfect replica（复制品）of Einstein, the Hong Kong-based tech company Hanson Robotics turned to the Hebrew University of Jerusalem, the home of the Albert Einstein archives（档案）. “We worked very closely with them to bring the product co marker,” the company’s Dr. Jeanne Lim said.
Einstein robot was introduced to the public at the Consumer Electronics Show in Las Vegas and was quickly hailed by those who saw it. “He became one of the breakout stars of the convention,” wrote Melia Robinson on Business Insider. “Crowds flooded into the company to have a look at the little guy.”
“Technology is often now very cold and socially isolating（孤立的）,” explained David Hanson, the co-founder of the company behind the new robot, “By bringing an lively character into our physical world, we’re humanizing（使人性化）the technology instead of dehumanizing the humans.”
As for Hanson Robotics, the company has been building human-size robots for over a decade.

Many of us know about Russia’s Take Baikal from our textbook, or by listening to Chinese singer Li Jian’s hit song, Lie Baikal. But over the years, the world’s deepest freshwater lake has been in the spotlight for an extreme sport.
Each March, about 150 people from around the world sign up for the Baikal Ice Marathon. The 26-mile（41, 84 kilometers）journey starts on the lake’s eastern shore. In March, the ice is a meter thick and iron-hard. Runners cross this frozen surface, finishing on the western side of the lake.

Former National Football League player and children’s author Tim Green has added another book to his list of accomplishments: Unstoppable. The book tells the story of a 12 year-old boy named Harrison, who survives life in a cruel lobster-home（寄养家庭）before he finally finds a loving family. Then he settles in and realizes his natural football ability but he loses his leg due to a deadly bone cancer. Unstoppable follows Harrison’s difficult life journey.
Tim Green said he decided to write a novel about a kid facing cancer after watching how his wife fought to survive her own illness. “Her mental and physical toughness were more heroic to me than anything I’d ever seen in the national sports leagues,” Green told TFK.
Green said, he knew he needed to write about a person who struggled through a serious illness. But because the target age for his books is the teen, he needed to tell the story through the eyes of someone of that age. He needed a perfect real story on which to base his book.

TFK asked Keith what it felt like to read Unstoppable for the first time. “Tim captured what it felt like for me to go through this experience and battle back, “Keith said.” Tim’s look sends a message to all the kids across the country that are facing challenges and that have nothing to do with cancer; you are all unstoppable, as long as you believe it.”
