Boys and girls,as we all know,most people,especially young people ,tend to care about their hair much because hair plays a very important role in our appearance.But can you imagine what other uses hair has?Do you have any idea that human hair may become a new solar energy soutce?Before we begin with the new content of our Physics ,let me tell you a new invention first. It's reported that a Nepali teenager has designed a $32 solar panel using human hair. Milan Karki,who is 18 years old and lives in a village in rural Nepal,used human hair to replace silicon ,which is a common but expensive componet of solar panels. By using hair as a replacement,Karki says that solar panels can be produced for around $32,a price that could be halved if they were mass-produced. The solar panel works,because melanin ,which gives hair its colour,is light sensitive and can act as an elecrtical conductor.Kaiki was inspired to think of the idea by a Stephen Hawking book ,which explained how to create elecrtic energy from hair. The device that Karki has invented is capable of producing 9V or 18V of energy--plenty to charge a mobile phone. "Half a kilo of hair can be bought for only 16p in Nepal and lasts a few months;whereas a pack of batteries would cost50p and lasts few nights,"according to The Daily Mail. The solar panel is claimed to be easy to service as the hair is easy to replace. Karki has now seng out several devices to other disrticts near his home for tetimg .He said,"First I wanted to provide elecricity for my home,then my village .Now I am thinking for the whole worle." So next time when you have a haircut,do remember to keep your hair cut down to use for energy.Perhaps you can also provide elecrticity for your home,even your village using your own hair. Which of the following is true about the new invention? A) We can buy solar panel for around $32 using hair as a replacement in the market. B) The device can produce 9V or 18V of energy. C) Karki thought of the idea of inventing the device all by himself. D) Kaiki provides elecrticity for his home using hair.

(Question)
Do you sometimes argue about what seems to you to be simple fact? Do you argue whether it's cold outdoors or whether the car in front of you is going faster than the speed limit? If you get into such arguments, try to think about the story about the six blind men and the elephant. The first blind man who felt the elephant's trunk said it was like a snake. The second who felt the elephant's side said it was like a wall, while the third said it was like a spear as he touched the animal's tusk. The fourth, who got hold of the elephant's tail insisted that it was like a rope. The fifth man said it looked like a tree as he put his arms around one of the elephant's legs. The sixth, who was tall and got hold of the elephant's ears, said it was like a huge fan. Each man's idea of the animal came from his own experience. So if someone disagrees with you about a "simple fact", it's often because his experience in the matter is different from yours. To see how hard it is for even one person to make up his mind about a "simple fact", try this simple experiment. Get three large bowls. Put ice water in one. Put hot water in the second. Put lukewarm water in the third. Now put your left hand in the ice water. Put your right hand in the hot water. After thirty seconds, put both hands in the lukewarm water. Your right hand will tell you the water is cold. Your left hand will tell you it's hot! Which of the following temperatures can the word "lukewarm" be applied to? A) Around 1degC B) Above 60degC C) Around 25degC D) Below 0degC
