Indian-origin Anvitha Vijay has given a new meaning to the phrase “age is just a number”; she has proved that achievements and knowledge follow passion and not just age and experience.

    Vijay, who lives with her parents in Melbourne, Australia, at the age of seven realized that her piggy bank did not have enough money to hire a developer to make her an app, so she decided to teach herself how to code. With the help of YouTube videos, the young techie learned to code. For one entire year, she watched multiple coding tutorials on the web and became a programmer herself.

    Vijay's inspiration for developing the apps was her little sister, who was still learning to talk. Therefore, Vijay developed an educational app for children that were her sister's age. The app is called Smartkins, which uses about 100 sounds and flashcards of different animals that help children learn and identify. Later, Vijay developed a similar iOS app for children to identify and learn colors. Each app has been downloaded thousands of times.

    Anvitha's skills won her a scholarship to attend a big tech conference hosted by Apple in San Francisco, California. There, she got tips from the pros. She went to workshops where she learned about the latest software for app building.

    All that training led to an idea for a third app. This one, called GoalsHi, inspires kids to practice good habits. Users are rewarded for achieving goals, such as eating their vegetables or practicing piano. Anvitha says the rewards are like getting a sticker for a job well done.

    Anvitha's goal is to continue creating technology that helps kids learn while having fun. But even more important to her is that the world sees the power of technology in kids' hands. “The more training we get in tech at an early age,” she says, “the better chance we have of becoming creativity champions who will one day change the world.”

    Sixteen years ago, I learned an important life lesson in the back of a New York City taxi.

    I was on my way to Grand Central Station, and we were driving in the right lane when a black car suddenly sped out of a parking space right in front of us.

    My driver fit the brakes hard, skidded, and missed the other car by a few inches. The driver of the other car, the man who had just nearly caused a huge accident, started shouting at us. My taxi driver just smiled and waved at him. He was really friendly!

    “Why did you just do that?” I asked him. “This guy almost destroyed your car and could have sent us to the hospital!”

    This was when my taxi driver told me what I now call “the Law of Garbage Trucks”.

    “Many people are like garbage trucks. They run around full of garbage, full of anger, and full of disappointment,” he said. “As their garbage piles up, they need a place to dump it, and if you let them do, they'll dump it on you. So when someone wants to dump on you, just smile, wave, wish them will, and move on. You'll be happier because of what you have done.”

    I started thinking, how often do I let Garbage Trucks run right over me? And how often do I take their garbage and dump it on other people—at work, at home, or on the street? It was on that day that I said, “I'm not going to dump anymore.”

    Stephen Hawking was born in Oxford, England on 8th January, 1942. He went to school in St Allbans, a small city near London. Although he did well, he was never top of his class.

    After leaving school. Hawking went first to Oxford University where he studied physics and then went to Cambridge University where he studied cosmology(宇宙学）. As he himself admits, he didn't work hard. He was a very lazy student, and did very little work. However, he still got high marks.

    It was at the age of 20 that Hawking first noticed something was wrong with him. He started to bump into things. When he visited his family at Christmas time, his mother was so worried that she made him see a doctor. Hawking was sent to hospital for tests. Finally, the result came back. Hawking had motor neuron disease (运动神经元病）, an incurable illness which would make him unable to speak, breathe or move without the help of a machine. Doctors said they had no way to help him. He would die before 23.

    At first, Hawking became very depressed. After a while, though, he began to see his life in a different way. As he later wrote, "Before my illness was diagnosed(诊断), I had been very bored with life. There had not seemed to be anything worth doing. But shortly after I came out of hospital, I suddenly realised that there were a lot of worthwhile (值得做的）things I could do." Then Hawking got married and found a job at Cambridge University as a professor, He strongly believes that his story shows that nobody, how bad their situation is, should lose hope. "Life is not fair." He once said. "You just have to do the best you can in your own situation."

    I live on the West Coast of British Columbia with my husband and three children. Our day started like any other day. My husband left for work in the north of the town, which is an hour and a half's drive. The younger children caught their bus to school ten minutes away. Our oldest attends high school and is a 40-minute drive away. I work at home in the office, working on the computer.

    It was November 2006 and the news had reported gusty winds. When the winds started to get strong I shut the computer down and tried to phone my husband. I left a message telling him the winds were blowing at 80 to 90 km/hr. As I hung up the phone, I heard a tree crack. I went outside and stood in the driveway. Another tree exploded and my heart was racing.

    When the school bus carrying the youngsters arrived, I ran to get them. No sooner had we made it to the house than another tree exploded. The children were clearly scared, so I loaded them up into the car and we parked in the middle of the yard, where no trees could land on us, it was starting to get dark.

    My oldest son didn't come home on the bus and my husband was stranded at work. I called the high school and reached my son. He said he was stranded and didn't know what to do. I called a friend in town for help. He managed to get my son home to me. Finally, my husband managed to get home.

    We had been prepared for such events, as we had a generator, candles, a wood stove, fresh water, batteries and two freezers full of food. We were without power for five days. But we didn't panic we had all the emergency equipment we needed. Thankfully, none of our neighbours were injured, but the damage was extensive. We are witnessing climate change. We need to be prepared.

    One family, which moved from Japan and settled at the turn of the century near San Francisco, had built a business in which they grew roses and trucked them into San Francisco three mornings a week.

    The other family also marketed roses. For almost four decades the two families were neighbors, and the sons took over the farms, but then on December 7, 1941, Japan attacked Pearl Harbor. Although the rest of the family members were American, the father of the Japanese family had never been naturalized. As they planned to leave the country, his neighbor made it clear that, if necessary, he would look after his friend's nursery (花圃). It was something each family had learned in church-Love the neighbor as themselves. "You would do the same for us," he told his Japanese friend.

    It was not long before the Japanese family was transported to a poor landscape in Canada. A full year went by. Then two. Then three. While the Japanese neighbors were in Canada, their friends worked in the greenhouses. Sometimes the father's work could stretch to 16 and 17 hours. And then one day, when the war in Europe had ended, the Japanese family packed up and boarded a train. They were going home.

    What would they find? The family was met at the train station by their neighbors, and when they got to their home, the whole Japanese family were shocked. There was the nursery, complete, clean and shining in the sunlight, neat, prosperous and healthy. And the house was just as clean and welcoming as the nursery. And there on the dining room ground was one perfect red (玫瑰花蕾), just waiting to unfold-the gift of one neighbor to another.

Brilliant Ways to Deliver Secret Messages

Many effective ways are used now to deliver secret messages. But in the past when the science and technology was not developing, especially during the war, how did people send secret and important messages?

Shoelaces

In the 1950s, the U.S. Central Intelligence Agency created a book of tips to teach spies ways to communicate in public. One tip: Lace up your shoes. Tied one way, the laces might mean "I have information": tied another, "Follow me". The spies could communicate while everyone else probably thought, "That guy can't tie his shoes correctly!"

Tattooed (刺文身) Head

Around 513 B.C., Histiaeus was forced out as the ruler of an ancient city. So he wanted to send a message to his supporters: Rebel against the king who took away his power.

Histiaeus called in a slave, shaved his head and tattooed the message onto the man's skin on the top of head. After the slave's hair grew back, he travelled to Greece with orders to shave his head again. Message received!

Orange Juice

In 1597, John Gerard was imprisoned in the Tower of London in England. He asked the prison guard to let him send letters written in charcoal (木炭). But then he wrote another message on top using the juice from an orange-which was only visible when the juice was dry and the page heated. With his invisible ink, he escaped successfully.

Songs

In the 1800s, African American slaves couldn't talk openly about their plans to escape to freedom—so they secretly sang about it.

Swing Low, Sweet Chariot might sound like a religious song. But for slaves, the "sweet chariot" was the code for the Underground Railroad, the network of people who helped slaves head to northern states and Canada. The song Wade in the Water warned escaped slaves to get in the water so dogs wouldn't smell them. With these songs, hundreds of people escaped slavery.
