The percentage of women working in technology has decreased since the 1990s.Women make up only a quarter of all jobs in computer and math professions.I think all girls should learn how to code（编码）.Here is why.

    If we want to be part of one of the fastest growing job markets out there,we need to jump on board!Over the last ten years the growth in STEM jobs has been three times faster than that in non-STEM fields.Women will never be able to keep up with men in the professional workplace if we don't join the fastest growing fields.

    Just like hundreds of years ago,people who could read and write controlled the future,and now those who are at home with technology will shape the world we live in.You can use coding in every aspect of your life,even if you don't enter a field that involves coding.You cant use coding to create your own website or to program games.You can animate your YouTube videos,or make graphic designs.Programming is now being used in every profession, including medicine and airplane design.

    You can have fun creating your own website,programming a robot to get the remote for you when you're lying on the couch,photoshop pictures to change the color scheme to something better than the Instagram filters,and so much more.Coding allows you to realize your wildest dream,and create anything you can imagine.Coding allows you to rule the world.

    It's not very hard to learn to code.You could learn to code on YouTube,in the Girls Who Code club;you could take a free course online on Code Academy;you could even just Google how to code.

You learned to read,you learned to drive-now learn to code.

    There's a new frontier in 3D printing that's beginning to come into focus: food. Recent development has made possible machines that print, cook, and serve foods on a mass scale. And the industry isn't stopping there.

     Food production

    With a 3D printer, a cook can print complicated chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Foodini to "re-create forms and pieces" of food that are "exactly the same," freeing cooks to complete other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

    Sustainability(可持续性)

    The global population is expected to grow to 9.6 billion by 2050, and some analysts estimate that food production will need to be raised by 50 percent to maintain current levels. Sustainability is becoming a necessity. 3D food printing could probably contribute to the solution. Some experts believe printers could use hydrocolloids (水解胶体) from plentiful renewables like algae(藻类) and grass to replace the familiar ingredients(烹饪原料). 3D printing can reduce fuel use and emissions. Grocery stores of the future might stock "food" that lasts years on end, freeing up shelf space and reducing transportation and storage requirements.

    Nutrition

    Future 3D food printers could make processed food healthier. Hod Lipson, a professor at Columbia University, said, "Food printing could allow consumers to print food with customized nutritional content, like vitamins. So instead of eating a piece of yesterday's bread from the supermarket, you'd eat something baked just for you on demand."

    Challenges

    Despite recent advancements in 3D food printing, the industry has many challenges to overcome. Currently, most ingredients must be changed to a paste(糊状物) before a printer can use them, and the printing process is quite time-consuming, because ingredients interact with each other in very complex ways. On top of that, most of the 3D food printers now are restricted to dry ingredients, because meat and milk products may easily go bad. Some experts are skeptical about 3D food printers, believing they are better suited for fast food restaurants than homes and high-end restaurants.

Training the Brain

    People who can accomplish unbelievable tasks, such as memorizing thousands of random numbers in under an hour, state that they just have normal brains. Some memory superstars compete in Olympic-like World Memory Championships. These mental athletes, or MAs for short, can memorize names of dozens of strangers in a few minutes or any poem handed them. Ed Cooke, a 24-year-old MA, explains they see themselves as participants rescuing the long-lost art of memory training. These techniques existed not to recall useless information, but to cut into the brain basic text and ideas.

    A study in the journal Nature examined eight people who finished near the top of the World Memory Championships. The scientists examined whether their brains were fundamentally different from everyone else's or whether they were simply making better use of memorizing abilities we all possess. They put the MAs and control subjects into brain scanners and had them memorize numbers and photographs. The result surprised everyone. The brains of the MAs and those of the control subjects were indistinguishable. On every test, the MAs scored in the normal range. However, when the scientists examined what part of the brain was used during a memory activity, they found the MAs relied more heavily on areas in the brain involved in spatial memory.

    MAs offer an explanation: anything can be fixed upon our memories and kept in order by constructing a building in the imagination and filling it with pictures of what needs to be recalled. Dating back to the fifth century, the building is called a memory palace. Even as late as the fourteenth century, when there were copies of any text, scholars needed to remember what was read to them. Reading to remember requires a different technique than speed reading. If something is made memorable, it has to be repeated. Until relatively recently, people read only a few books intensively (细致地) again and again, usually aloud. Today we read extensively, usually only once and without continuous focus.

    So the great difference is the ability to create impressive pictures in mind and to do it quickly. Using memory palaces, MAs create memorized pictures. For example, recombine the pictures to form unforgettable scenes such as the ways through a town. One competitor used his own body parts to help him memorize a 57,000-word dictionary.

    Anyone who wishes to train the mind needs first to create fantastical palaces in the imagination. Then they should cut each building into cubbyholes for memories. In a short amount of time, they will notice improvement with remembering things. To keep the skill sharp, MAs deliberately empty their palaces after competitions, so they can reuse them and they recommend that beginners do the same.

    Sandi Patty has been a name synonymous (同义的) with Gospel music because of her singing ability since she released her first album in 1979.

    Patty's newest book. The Voice, takes a deep dive into parts of her life she's kept private for years. Surprisingly, The Voice is not primarily concerned with Patty's singing voice. Patty was always a talented singer. However, she struggled to find her inner voice and speak up for herself. "I was a shy kid. Words were hard for me," Patty said.

    One of the reasons why Patty found it so difficult to use her voice was a traumatic childhood experience. At age six, she was abused by a friend, an experience she opened up for the first time in the book.

    She is sharing the story of her experience now, hoping it will help other people feel less alone. "Feeling alone keeps everybody silent about the tough times in our lives, so we think we're the only ones," Patty said. She wrote in The Voice that she felt like it was her job to make everyone feel better.

    Friendships were essential for helping Patty find the courage to speak up. They reminded her that she didn't need to make others feel better because the people she loved didn't doubt she cared for them.

    Friends and family were crucial for helping Patty confront another struggle she faced—shame. She felt unpleasant for insecurities about her weight and her divorce. "I've heard it explain that guilt tells us we have done something wrong and shame says we are wrong," Patty said.

    "I want people to know that their stories and their voices matter," Patty said. "We have to figure out a way to take our pain away and put it where it needs to be, without letting it guide our lives. Pain is a part of our story. It describes us, but it doesn't need to define us."

    Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

    Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self­conscious (难为情) when they're in poorly lit places—and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

    Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us feel less hungry. So when it's time to repaint, go blue.

    Don't forget the clock—or the radio. People who eat slowly tend to consume about 70 fewer calories (卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at least 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turn on relaxing music. It makes you less likely to rush through a meal.

    Downsize the dishes. Big serving bowls and plates can easily make us fat. We eat about 22 percent more when using a 12­inch plate instead of a 10­inch plate. When we choose a large spoon over a smaller one, total intake (摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.
