question: What would life be like if you give up using your cell phone? Will it become boring? Twenty-eight eighth-graders at St. Matthew School in San Francisco will tell you it can still be rich and colorful. These students took part in their school's "tech-free" challenge. They couldn't use cell phones for two weeks from Nov 11 to Nov 22. The idea was to help students understand how technology has affected their lives, said Denise Uhl, principal of the school. Uhl did a survey on technology usage among the eighth-graders before thinking of the challenge. She found that 84 percent of the students said they didn't like it "when everyone was on their cell phones", but they didn't know what to do about it. The answer was actually easy --- to stop constantly using cell phones. To help students understand the point, Uhl created the activity. It was warmly welcomed among students. "I wanted to sign up for the tech-free challenge because it was just really a good idea to do it," eighth-grader Joe told local newspaper Catholic San Francisco. "I wanted to get closer to my family. And it really worked. I started to hang out with my family more. We watched more family movies and we played a lot of board games." The activity also helped students develop their interests. During the two weeks, Lucas said he spent much more time outside, picking lemons in his garden. Maddie finished a painting and Cassie created a scarf on a loom .

question: Rudy Saldia is a 25-year-old postman from America. Every day he rides to deliver parcels across his hometown of Philadelphia with his six-month-old cat called MJ always sitting on his shoulders. MJ, short for Mary Jane, is different from other cats. She was born in a drawer in Rudy's bedroom on April Fool's day. When she got older, Rudi noticed that her favorite place to rest was his shoulders, so he decided to train her to work with him. "The first day we crossed one block. The next day we tried two blocks and now we can ride about 25 miles every day. MJ enjoys moving around on my shoulders," Rudi said. However, Rudy hopes to be able to ride 100 miles with MJ in the coming day. "People are always surprised and excited to watch us. I often hear someone shout, 'Oh, my God, he has a cat on his shoulder! How lovely that is!' MJ is so comfortable on my shoulder and she never hurts me with her claws. We always get on well with each other and have a great time during the work." Rudy smiled. MJ loves noisy streets of Philadelphia, the only problem is that she is scared of the siren . However, her owner Rudi is always there for her. One day, if you go to Philadelphia and see a postman with a cat on his shoulder, don't be surprised!

question: Philosophers in antiquity used the concept of force in the study of stationary and moving objects and simple machines, but thinkers such as Aristotle and Archimedes retained fundamental errors in understanding force. In part this was due to an incomplete understanding of the sometimes non-obvious force of friction, and a consequently inadequate view of the nature of natural motion. A fundamental error was the belief that a force is required to maintain motion, even at a constant velocity. Most of the previous misunderstandings about motion and force were eventually corrected by Galileo Galilei and Sir Isaac Newton. With his mathematical insight, Sir Isaac Newton formulated laws of motion that were not improved-on for nearly three hundred years. By the early 20th century, Einstein developed a theory of relativity that correctly predicted the action of forces on objects with increasing momenta near the speed of light, and also provided insight into the forces produced by gravitation and inertia.
