3 . One day, you might be ordering your favorite pizza from a robot.Researchers at a university in Pittsburgh, Pennsylvania, are working on creating a pizza-making robot.

“Robots are basically preprogrammed to repeat the same actions over and over,” says David Held, a robot expert from Carnegie Mellon University, and one of the members of a pizza-making team．But making pizza has challenges.For instance, the flour (面粉) will become squishy when meeting water, with a shape that can change in many ways.Also, pizza-making requires many steps—such as rolling and cutting—and several tools, including a rolling, a knife and so on.In what order should the steps be done? Which tools should be picked, and when? “If you need to do a cooking task, there are several levels that you have to reason about,” Held says.Once people get the hang of it, “We don’t even need to think about exactly how we’re doing it- it sort of just happens.But robots can’t really “understand what to do on their own”.

To start, the team used a computer to consider how a robot could lift, fatten, gather, move and cut dough (生面团).The method has two levels of robotic reasoning: one that thinks how it should approach the overall task, and the other that thinks how it should move its “hands” to perform each action．The result was better than with the usual programming techniques.“We got a little bit closer to the right shape than the former methods,” Held says．“‘But there’s still a lot of room for improvement.”

For now, people will continue to make pizza the old-fashioned way: with their own hands.Sill, a pizza-making robot is a good goal.And if a robot could deal with dough, it could also work with other objects that can change shapes.“You can imagine robots helping in hospitals, or robots that clean up toys in day cares,” Held says.“The general goal is to eventually have robots that can help with whatever the task may be.”

4 . The week my eldest son finished pre-school education, I decided to clear out the playroom filled with his toys. Toys had kept him company whenever his mother and I were busy with other duties, and over the years we had collected a really large number of them. Here are some of what I found: 13 puzzles, 4 games for practising maths, and a speaker box that could play Mozart to develop musical ability.

Our masses of playthings may have been extreme, but it was by no means unusual. American families spend, on average, around 600 dollars every year on toys; a 10-year-old child in the UK may have owned 238 toys, totaling about 6,500 pounds.

During the past two centuries, educators, toy companies and parents like us have acted as if the purpose of play is to prepare children for adulthood. The more book learning we could pack up as play, and then give to our children, the better. Then, in the second half of the 20th century, toys were increasingly bought for the purpose of building better brains in order to build more competitive and successful grownups. By 2020, the different kinds of educational toys had made nearly $65 billion worldwide. Toys that teach — from the Speak & Spell to the See & Say — are now a part of many young lives.

“This generation of parents is asking toys to provide an end product, and that end product is success,” Richard Gottlieb, an influential toy industry advisor, commented. “They want toys to get their children into Harvard.”

“The model has been, ‘If I get toys that do schoolish things, then that’s good,’” Alison Gopnik, a leading developmental psychologist, said. “But that really goes against what the developmental science is telling us. For a long time, we’ve been getting our children, and their toys, all wrong.”

5 . It was the first run of a family ski weekend in Colorado.The perfect spring morning greeted us with clear skies and a warm temperature.We planned the course on the mountain map and set off.Then, three minutes into the run, my left ski came off; then my right ski turned over and took my leg with it, and then I heard the sharp sound.I lay on the snow, screaming.My brother and husband stopped and took me down the mountain to the hospital．

After an operation, the doctor told me that I wouldn’t walk for three months.It seemed like a blow.“How can we get everything done?” I turned to Adam, my husband.Who would get the kids to the bus at 7:15 a.m. , since my husband was in his office by 6 a.m. each day? Who would deal with the two dogs? Who would prepare dinner? Who would drive to tennis practices? “We’ll work it out,” Adam said.I nodded, because we didn’t have the other choice．

But something unexpected happened: friends both near and far were searching for ways they could help.Parents at our school bus stop offered to drop my kids off each afternoon.My kids ran up the steps each day to check on me.My husband, the man who, in the past, had to be told what to do and when to do it, pulled our family back up.

Finally, I returned to the shopping and the bus pickups. I made dinners again.I organized everyone and sent them out the door.But something had changed in our family, in me.Now I am quicker to ask for help if I am the one needing.
