    Each morning Grandpa was up early sitting at the kitchen table, reading his book. His grandson wanted to be just like him and tried to copy him in every way he could.

One day the grandson asked, "Grandpa, I try to read the book just like you, but I don't understand it, and I forget what I understand as soon as I close the book. What good does reading the book do?"

The grandpa quietly turned from putting coal in the stove and replied, "Take this coal basket down to the river and bring me back a basket of water."

The boy did as he was told, but all the water leaked out before he got back to the house. The grandpa laughed and said, "You'll have to move a little faster next time," and sent him back to the river with the basket to try again. This time the boy ran faster, but again the basket was empty before he returned. Out of breath, he told his grandpa that it was impossible to carry water in a basket, so he went to get a bucket instead. The grandpa said, "I don't want a bucket of water; I want a basket of water. You're just not trying hard enough." The boy again dipped the basket into the river and ran hard, but when he reached his grandpa the basket was empty again. Out of breath, he said, "Grandpa, it's useless!"

"So, you think it is useless?" the grandpa said, "Look at the basket."

    The boy looked at the basket and for the first time he realized that the basket was different. It had been transformed from a dirty old coal basket and was now clean.

"Grandson, that's what happens when you read the book. You might not understand or remember everything, but when you read it, you'll be changed, inside and out."

    When it comes to the Internet, people talk about the password most. Actually, it's been under fire for a long time. Research has shown that passwords are not a very good way to protect sensitive information.

    People would use some random characters, numbers and symbols. Furthermore, a unique password would be used for every site or application the user uses. Unfortunately, the longer and more complex passwords become, the more people are likely to forger them. Therefore, they use the same password for every service or application. These are all big no-noes and essentially defeat the purpose of a password.

    Google is trying to kill off passwords on Android devices by introducing the Trust API, which does what simple passwords cannot and gives developers a framework for securing their application using a number of security systems and metrics(衡量标准)on the device. A Trust Score will be generated based on a number of metrics including your device location, face scanning, fingerprints, and the things like your typing speed or the way you speak. Taken one at a time, these metrics are not secure. But taken together, these metrics will help recognize the real “you”.

    The good news is that Google has already been testing this on real world data. Google has proven the Trust API works. Next Google will run tests will some banks to see if the Trust API meets their needs before rolling out the system on Android phones later. It may take another year for apps and popular sites to start using the Trust API.

    This is a pretty exciting change. Passwords have been around for a lone time. Although the security of systems has been improved, the usability of systems hasn't been proved much. Google appears to have the best of them. Maybe that never-ending conflict between security and convenience will be able to take a break once the Trust system comes out.

    Space is where our future is — trips to the Moon, Mars and beyond. Most people would think that aside from comets(彗星) and stars, there is little else out there. But, since our space journey started we have left so much trash(垃圾) there that scientists are now concerned that if we don't clean it up, we may all be in mortal(致命的) danger.

    The first piece of space junk was created in 1964, when the American satellite Vanguard Ⅰ stopped operating and lost its connection with the ground center. However, since it kept orbiting around the Earth without any consequences, scientists became increasingly comfortable abandoning(抛弃) things that no longer served any useful purpose in space.

    It is estimated(估计) that there are now over 500,000 pieces of man-made trash orbiting the Earth at speeds of up to 17,500 miles per hour. The junk varies from tiny pieces of paint chipped off rockets to cameras, huge fuel tanks, and even odd items like the million-dollar tool kit that astronaut Heidemarie Stefanyshyn Piper lost during a spacewalk.

    The major problem with the space trash is that it may hit working satellites and damage traveling spacecraft(飞船). Moreover, pieces of junk may collide(碰撞) with each other and break into pieces which fall back to the Earth. To avoid this, scientists have invented several ways for clearing the sky. Ground stations have been built to monitor larger pieces of space trash to prevent them from crashing into working satellites or space shuttles. Future plans include a cooperative effort among many nations to stop littering in space and to clean up the trash already there.

    If Confucius (孔子) were still alive today and could celebrate his September 28 birthday with a big cake, there would be a lot of candles. He'd need a fan or a strong wind to help him put them out.

    While many people in China will remember Confucius on his special day, few people in the United States will give him a passing thought. It's nothing personal. Most Americans don't even remember the birthdays of their own national heroes.

    But this doesn't mean that Americans don't care about Confucius. In many ways he has become a bridge that foreigners must cross if they want to reach a deeper understanding of China.

    In the past two decades, the Chinese studies programs have gained huge popularity in Western universities. More recently, the Chinese government has set up Confucius Institutes in more than 80 countries. These schools teach both Chinese language and culture. The main courses of Chinese culture usually included Chinese art, history and philosophy (哲学). Some social scientists suggest that Westerners should take advantage of the ancient Chinese wisdom to make up for the drawbacks of Westerners philosophy. Students in the United States, at the same time, are racing to learn Chinese. So they will be ready for life in a world where China is an equal power with the United States. Businessmen who hope to make money in China are reading books about Confucius to understand their Chinese customers.

    So the old thinker's ideas are still alive and well.

    Today China attracts the West more than ever, and it will need more teachers to introduce Confucius and Chinese culture to the West.

    As for the old thinker, he will not soon be forgotten by people in the West, even if his birthday is.

    I was selfish as a teenager. I usually spent my time thinking about myself and taking care of my own needs. I let my older brother do most of the work around the house until he left for college. I let my mom and dad worry about our bills and problems while I read books, played, and lost myself in my own imagination. This didn't change even when I went to college either. I studied hard but only to make my own life better. Even when I started to explore my faith, it was only to increase my own happiness.

    I married after graduation and decided to start a family. Of course, I had no idea what hard knocks reality had in store for my selfish soul. Soon I found myself unemployed, deeply in debt, and with a new baby on the way. I found out that life has little sympathy for spoiled people. In fact, all of the struggles I was going through were beating the selfishness slowly out of me.

    Still, I didn't give up on happiness. I knew that there must be a way to find it. I finally realized, however, that it had to include more than just my own needs, wants, and desires. The answer began to make itself clear one night shortly after my baby boy was born. I got a bottle and held him in my arms. As I was feeding him I looked down and saw his big, innocent, trusting eyes. I smiled and talked to him. Then he smiled and I could feel my heart growing, expanding with love. I felt such peace and joy. At that moment I had a hint of the truth: it is by growing our hearts with love that we find our happiness.

    Carolyn Arends wrote:" The more people you let into your heart, the bigger your heart gets. The more love you get, the more love you have to give. It just keeps growing." So, keep loving, keep living and keep caring. Keep growing your heart today, tomorrow, and always.
