Today, after more than 30 years of development of information and communication, we are still discussing whether books will be completely replaced by e-books, but the fact that we are in front of us is that a 5-year-old child using a tablet computer as a toy has a myopia of 150 degrees. Graduation in high school may reach 800 to 1000 degrees; when he is old, the rate of retinal detachment is 5 to 10 times higher than that of ordinary low-degree myopia. This is a warning. Today, people use a lot of mobile phones to read. There is hardly any report in the country about the electronic media using Roman alphabet and the media using traditional Chinese characters. Under the three hours of reading every day, how much eye fatigue is there. The gap, because the colored RGB screen is not friendly to the strokes of Chinese characters, perhaps a little better in the horizontal stroke, but the straight stroke is divided into three color lines, plus 15 strokes, 20 strokes or more, at 12 In the rough color dot matrix of ×12, it is terrible to watch with a magnifying glass. Another problem is that the paper media not only uses 1200dpi (newspaper) and 2540 dpi (commercial printing) high resolution, but the computer diagonal 32-inch screen, only 1080~1200 pixels left and right, today's high-resolution HD screen is only 2000 pixels. The 4K screen is 4000 pixels, which is quite different from the high resolution of books without flashing signals.
It is undeniable that the animations and games of computers and smart phones have a lot of changes and sound and light effects, but they are far from the stable display of the print media, but they are similar when you play without memory. If you want to understand and remember, especially we use When writing a lot of Chinese characters, the learning of the screen is like a dream of floating in the sky, and the effect is quite different. This has long been recognized by the academic circles. For example, the mayor of Ke Wenzhe, Taipei City, has driven away from the paper media from the middle school, although it has its focus and benefits. However, in order to settle in a structured and in-depth thinking, it is still more appropriate to use printed paper media, because the reading speed can be freely played, and the electronic media must consume a lot of spirit in the "words and words", because in the resolution Under the influence of the RGB grid, the horizontal line of the font is still good, and the straight line is very difficult to read and discern. The ophthalmologist calls for the direct view of the blue light of the screen backlight and the recognition of the font and the word stroke. It is not only the physiological vision of the eyeball, but also the tension of the brain optic nerve due to the long-term tension. Under the occurrence of pseudo-myopia, after a long time can not be restored to become the increase of true myopia, this is not caused by one time but more and more serious after watching the years, this situation is like a predecessor in the printing industry, Due to the busy business, the mobile phone does not leave the left ear. In 7 or 8 years, the left ear only hears the audio of the mobile phone. When talking with people, only the right ear can hear the words of others, and the left ear can not hear the voice of others! However, such nerve effects are believed to occur also in the light reception of the visual electronic frequency to the screen. The mayor of Ke Wenzhe only saw the near-profit, but if he had a long-term concern, he might not be able to wait for it. Otherwise, once visual variability occurs, it often fails to come back.
Some people think that using paper is equivalent to cutting down native forests. This kind of cognition is like eating a piece of pork. The number of wild boars on the mountain will be the same. Today, there are very few native forests in the wilderness. Papermaking has been made from artificial forest trees. Some of them use paper made from modified forest trees to make paper and paper. A coniferous wood is 80 years old and has been used for hundreds of years. To make pulp, but to remove the sapwood after the beam and column and the angle material, and slice it to make the pulp. The quality is also indistinguishable, but the cost is very low, and the recycling rate of waste paper in the world reaches 65%. It also means that only about 1.4 tons of new pulp is used in 400 million tons of paper per year, and the other 260 million tons are recycled pulp. The energy consumption is much less than that of new pulp, and the storage of wood is more environmentally friendly. On the contrary, the manufacture of a computer, mobile phone, and tablet requires a lot of materials, including metal and glass, and various photosensitive etched semiconductors, electronic circuits of screens, grids or other lines, and toxic wastes and gases are generated. One ton of paper is less than one thousand dollars, and the production cost of one ton of electronic and optoelectronic products is very amazing. When used, it can't be as quiet and energy-free as books and paper media. Therefore, electronic products are the energy consumption of lithium batteries. It’s amazing. It’s charging for two days. It’s producing 45 million tons of electronic products every year in the world. It’s less than 10% recycled. The recoverable gold is about 300 tons and the silver is about 1,000 tons. It’s worth a lot of money. The pollution of solution, pickling and electrolysis is beyond everyone's imagination. Some people in Africa who are engaged in dismantling and recycling are very young and have problems with cancer and cancer. They work in a non-human life situation and look for a value of 15.2 billion. Recycling materials for the dollar. Compared with about 550 US dollars per ton of recycled pulp, 280 million tons worth 154 billion US dollars, and paper recycling is less polluting, less waste, especially toxic waste is very limited.
Therefore, the use efficiency of paper media is lower, but it has a more friendly use condition for human vision. In addition, it is very free to use electricity, can be stored for a long time, is not afraid of the program does not match, can not start, and the recycling is also very extensive. easy. The immediacy, rapid and extensive dissemination benefits of electronic media do have a great advantage, and the functions of animation and sound are difficult for paper media. The consumption of electricity by electronic media is not the biggest problem, but the compatibility. If a certain program can't match the content, this is the biggest problem, because the dye is placed after 7 or 8 years. Fading, the above memory content will be all zero, and the situation can not be read without the proper program at that time, and the paper media can be used as long as they can read the words and understand them.
At the Wan Guo Expo held in Osaka in 1970, Matsushita Electric Co., Ltd. made two huge stainless steel balls with a diameter of 1 meter. The clothes, cultural relics, books and daily necessities were placed in the ball, and two volumes were placed outside the book. The "audio tape" used as a music carrier was expected to dig a vacuum-sealed stainless steel ball in 2070 and open it to future generations to see people's lives and popular items a hundred years ago. The contents of the books stored in the book will feel very old, but at least some people will understand the Japanese characters, and the two tapes will definitely not have the equipment to be put in and out. Even if you can find the recording and playback machine in the 1970s in the museum, I believe there are many rubbers. And friction parts can not be used to drive the tape. Under the same principle, under the change of generations of faster and faster communication software, it is quite common to read today's memory contents in the next 10 years and 15 years. If you put some digital content on the cloud, it is very likely that you will lose it in two or three! I think about changing the mobile phone and telecom products for two or three years, and how to go to the e-waste. The cost and environmental protection cost are far higher than I imagined. After the development of TV media and computers, some people say books and papers. The media will be extinct, but so far it has come under the development of ICT media, and the book paper media will be reduced, but it will not disappear.
