While-reading An Invention That Changed the World Can you imagine a world without books, newspapers, or magazines? All of these things depend on one invention—papermaking. It, more than any other invention, was responsible for the rapid spread of information that shaped our modern world. In ancient China, many different materials were used to write on, such as animal bones, bronze wares, stones, wood, bamboo, and even silk. In the Western Han Dynasty, there was also a very early form of paper made from jute—a fibre that comes from plants. However, all of these materials were either difficult to use and store or very expensive. As the head officer of the palace workshop for the emperor in the Eastern Han Dynasty, Cai Lun became interested in trying to solve the problem. Different methods for creating something to write on were tried, but none were ideal. In his times, some kinds of bark—the outside part of trees—were used to make clothes. From past experiences, Cai Lun got the idea that bark, certain plants, and old clothes could be used to make a special material suitable to write on. In the first step of Cai Lun’s experiment, all the ingredients were mixed and boiled in water. Then, this material was beaten, cut up, and mixed with water again. Next, the liquid was poured over a bamboo screen, leaving just the fibre. Finally, this fibre was dried and pressed to form paper. To everyone’s surprise, this paper was soft, light, easy to make and use, and most importantly, cheap. In 105 CE, Cai Lun showed his creation to the emperor. The emperor was very pleased and praised Cai Lun for his great work. Later on, the papermaking technique did not only speed up the development of Chinese culture, but also changed civilizations around the world. It first spread to China’s neighbouring countries and finally reached Europe through Arabic countries in the 12th century. When the use of paper and printing came together in later centuries, it led to a rapid increase in the number of books. This resulted in a new birth of knowledge, creating the world we have today.

Young Inventors You may think that all inventors are adults with rich experience and university degrees, but you would be wrong. In fact, many famous inventions have been created by teenagers, just like you. Helping the blind to read At the age of three, Louis Braille became blind as a result of an accident. At a school for the blind, he was taught to read using books with raised letters. Blind people would run their fingers over the letters and guess their shapes. However, sometimes it was confusing because letters like “Q” and “O” were very similar, and they also took up too much space on a page. To solve these problems, a system was invented where letters were replaced with a code of raised dots. However, this new method was still too slow and difficult. At the age of 15, Braille made important improvements to the raised dot system. He made the code simpler and reduced the number of raised dots. Braille’s system was incredibly successful and is still used today around the world. Bringing entertainment to our homes In 1921, Philo Farnsworth was 14 years old when he read about the problem of creating an electric television in a science magazine and became interested in it. One day, while he was working on a farm, he noticed the straight rows of crops, and it gave him an idea. Perhaps an image could be broken down into lines, changed into electronic signals, and then sent through the airwaves. For years, Farnsworth worked to develop his idea, but he faced many challenges along the way. Many people did not believe his idea would work, and he found it difficult to get money to pay for his research. However, he never gave up. When he was 21, he eventually succeeded in sending a simple image using his invention. This breakthrough was an important step in creating the modern televisions that we use for entertainment today. These stories show that with a passion for solving problems, anyone can make a difference in the world, no matter how old they are. So, if you have an idea that you believe in, do not be afraid to go for it. Who knows? You may just be the next Louis Braille or Philo Farnsworth.
