Holi, also called the Festival of Colors, is a popular Hindu spring festival observed in India, Nepal, Bangladesh. It is celebrated at the end of the winter season on the last full moon day of the lunar month.Holi originally was a festival to celebrate good harvests. It developed to honor a legend from the Hindu Mythology（神话）. The story focuses on a cruel king, who hated his son,Prahlada. He attempted to kill his son but failed each time. Finally, the king asked his sister Holika, who was said to be safe in fire, to get rid of his son. However, when the aunt tried to burn Prahlada, it was the prince who ended up being safe in fire while the aunt herself was burnt to death. Holi honors this event every year and huge bonfires（篝火）are burnt on the eve of Holi. The festival spreads over 16 days. During these days people often have fun and play with colored powder and water. Holi is also celebrated with exciting parades which are companied by folk songs and dances.

    The festival begins on the night of the full moon. Bonfires are lit on street corners to drive away the air of evil spirits and bad feelings, and to symbolize the destruction of bad Holika, after whom the festival was named. In the morning, the streets are filled with people running, shouting and laughing.

    At noon, the craziness comes to an end and everyone heads to either the river or the bathroom, then relaxes and enjoys candies. A tired and contented silence falls over India.

    In October, I told the eight-year-olds in the class I teach in Pompton Lakes, New Jersey, about my plan. "Since all of you have done extra jobs around the house to earn some money," I said. "Then we'll buy food for a Thanksgiving dinner for someone who might not have a nice dinner otherwise."

    I watched them while they walked up and down the supermarket. "Flowers!" Kristine cried. The group rushed toward the holiday plants.

    "You can't eat flowers."——It was more sensible(明智的) to use any extra money to buy something that could be transformed(转换，转变) into meals.

    "But Mrs. Sherlock," came the begging voice, "we want flowers."

    Defeated finally, I put a pot of "funny" purple(紫色的) mums in the cart full of foods. "She'll like this one," the children agreed.

    An organization had given us the name and address of a needy grandmother who had lived alone for many years. We finally pulled up in front of a small house. A slightly built woman with a weary face came to the door to welcome us.

    My little group ran to get the food. As each box was carried in, the old woman kept on saying "Thanks"—much to her visitors' pleasure. When Amy put the mums on the counter, the woman seemed surprised. She's wishing it was a bag of flour(面粉), I thought.

    We returned to the car. As we fastened our seat belts, we could see the kitchen window. The woman inside waved goodbye, then turned and walked across the room, past the turkey, past the goods, straight to the mums. She put her face in their petal. When she raised her head, there was a smile on her lips. She was transformed before our eyes.

    The children were quiet. At that moment, they had seen for themselves the power they possessed(拥有) to make another's life better. The children had sensed(感到) that sometimes a person needs a bunch of funny purple flowers on a dark November day.

    An 80-year-old man was sitting on the sofa in his house along with his 45-year-old son. Suddenly a crow landed on their window. The father asked his son," What is that?" The son replied," That's a crow."

    After a few minutes, the father asked his son for the second time. The son said," Father, I told you just now. It is a crow." After a little while, the father asked his son the same question for the third time," What is that?" This time, the son said to his father in a low and cold tone," It's a crow, a crow."

    After a moment, the father yet again asked his son for the fourth time," What is that?" This time his son shouted at the father," Why do you keep asking me the same question again and again? I have told you already, ‘IT IS A CROW.' Are you not able to understand this?"

    A minute later the father went to his room and came back with a diary, which he had kept since his son was born. On opening a page, he asked his son to read that page.

    "Today my little son aged 3 was sitting with me on the sofa when a crow suddenly landed on the window edge. My son asked me 23 times what it was, and I replied him 23 times that it was a crow. I hugged him lovingly each time he asked me the same question. I did not at all feel angry, but instead felt affection for my son."

    If your parents reach old age, do not look at them as a burden, but speak to them gently, and be kind to them. From today say this aloud, "I want to see my parents happy forever. They have cared for me ever since I was a little child. They have always showered me with love. I will take care of my old parents in the BEST way no matter how they behave."

Fishy Weather Conditions

    Laj amanu, Australia, is a dry little town, sitting right on the edge of the Tanami desert. Can you imagines how surprised were people when live fish rained down on them from a dark gray cloudy. It happens that there are similar cases in England and Honduras.

    How do clouds make fishy. The simple answer is that they don't. There is a particular weather phenomenon(现象)called a waterspout. A waterspout is just like a tornado, only it forms above oceans, lakes, or rivers. Like a tornado, a waterspout moves in a circle at high speeds. When it moves above the water, it tends to carry the fish with it, as well as frogs or other small plants or animals.

    Scientists couldn't work it out at first. To make matters stranger still, the fish in Honduras were very much alive when they rained down to the ground, but they were all blind. In England and Australia, it rained fish and snakes, and none were blind. It was difficult to puzzle out, but the blind fish gave them a place to start.

    Scientists knew that some fish that lived in deep, underground caves with no light sources often lost their eyesight. So when blind fish rained down on Honduras, scientists began to connect some dots. Clearly, these particular fish were pulled from an underground water source by force.

    It has rained fish on every continent, and each time, people have tried in various ways to explain this strange phenomenon. Historically, villagers thought the “fishes from the heavens” might be answers to prayers for food.  Others suggested that floods overran river banks and oceans, leaving the fish on the city streets. No scientist had actually seen the rain as it occurred, only the fish left on the ground. But in 1990, a National Geographic team happened to be in Honduras when the Rain of Fishes began. They recorded what was happening and made history by finally proving that the fish really did fall from the sky.

    This huge breakthrough wasn't just a spot of good luck. It changed thousands of years of myths and legends into true stories and provided scientific explanations for how fish came to live in deep caves. It explained ancient cave paintings and shed new light on how species have spread over time. It turned out to be a lot more than just a little fishy weather.

Video calls are a common occurrence, but have you imagined being able to touch the person on the other end of the line? Scientists are making this a reality.

Researchers at the University of new South Wales, Australia have invented a soft skin stretch device (SSD). A haptic device that can recreate the sense of touch. Haptic technology mimics the experience of touch by stimulating localized areas of the skin in ways that are similar to what is felt in the real world, through force, vibration or motion.

Vibration is the most common haptic technology today and has been built into many electronic devices such as one attached to the back of the trackpad (触摸板) in laptops, which simulates a button clicking. However, haptic feedback with vibration becomes less sensitive when used continuously. The existing technology also has great difficulty recreating the sense of touch with objects in virtual environments or located remotely. According to Mai Thanh Thai, lead author of the study.

The new technology overcomes issues with existing haptic devices. The research team introduced a novel method to recreate the sense of touch through a soft artificial "muscles".

"Our three-way directional skin stretch device, built into the fingertips of the wearable glove we also created is like wearing a second skin-- its soft stretchable and mimics the sense of touch-- and will enable new forms of haptic communication to enhance everyday activities" said Thanh Nho Do, senior author of the study.

Imagine you are at home and you call your friend who is in Australia. You wear a haptic glove with the SSDs, and your friends also wears a glove with integrated 3D force sensors. If your friend picks up an object, it will physically press against your friend's fingers. And their glove with 3D force sensors will measure with interactions. The force signals can be sent to your glove so your device will generate the same 3D forces. Making you experience the same sense of touch as your friend.

The haptic devices could be applied in various situations, allowing users to feel objects inside a virtual world or at a distance. It could also be used in medical practices. Doctors can feel a patient's organ tissues. With surgical tools without touching them.
