The content of science and technology newspaper handwritten newspaper: science and technology change life

With the continuous development of science and technology, our living standard is as high as sesame blossom, and our life is also rich and colorful. It can be said that technology has changed our lives.

A long time ago, people could only send messages by putting written letters in envelopes and asking the postman to deliver them to the recipients. Now, the way of transmitting information has changed dramatically, and it can be easily realized by email or telephone. Thanks to modern communication tools, grandpa, who is now over 70 years old, has a bright smile on his face all day. Look, he is using his mobile phone to invite his old friends to visit Tai Ji Chuan in the park! Every time at this time, my grandfather will smile and say happily: "Now the technology is developed, and even our elderly people use the old mobile phone!" Yes, there are a large number of mobile phones for the elderly, and the sound is still very clear. As the saying goes, "seventy years old is rare", but now, even if you live to 80 years old, it is no longer rare. Look, grandma is also chatting with her cousin in Shenzhen on her mobile phone!

In the past, people used firewood to cook, and the baked food tasted terrible and smelled burnt, but now people use electric pressure cookers and microwave ovens. Look, grandma is already cooking with an electric pressure cooker! At this time, my grandmother said to me: "Now that technology is developed, the electric pressure cooker has been invented. This electric pressure cooker is really convenient! " "Yes, since our family has this pressure cooker, the cooking time has been shortened from the original 1 hour to tens of minutes, and the cooked food is very delicious and fragrant!

Dad started a company in Shenzhen as the boss. He went abroad for business trips many times, but because of the inconvenient transportation, it took him a long time to reach his destination, let alone to do things. However, with the development of traffic and the opening of high-speed rail, it is very convenient for dad to do things now, from the original four or five hours to two or three hours, which is really convenient!

I am a loyal "netizen", but don't get me wrong. I don't often play computer games, but I often use the computer to look up information, read news, send emails and participate in online competitions ... Unconsciously, the computer has become my "good friend". I remember one time, the teacher asked us to find out which one is "Three Sus". I thought hard and racked my brains, but I just couldn't think of it. Soon, I thought the computer was a "good friend", so I immediately searched the Internet for information. It turned out to be Su Zhe, Su Shi and Su Xun in the Song Dynasty. I can't help secretly marveling at how many functions computers have!

Today, we are fortunate to grow up in a brand-new era. The flower of science has never been so brilliant as it is today. I believe that as long as we cultivate our love for science, learn good habits in subjects and bravely climb the peak of science, our future life will be more colorful.

Science and technology newspaper handwritten newspaper information: wisdom life science popularization

Ink is used for writing. However, ordinary ink is difficult to eliminate after writing, which hinders the recycling of paper. Today, I saw a magical ink in the column "I love inventions".

According to Professor Dong Chuan, the inventor of this ink, "The magic of this ink is that it will disappear under the action of light and water after writing. Therefore, we named this ink' Fashion Ink'. " The reporter is a little unbelievable and is going to do an experiment to verify Professor Dong's ink.

The reporter prepared three kinds of paper: printing paper, writing paper and newspaper. First of all, the reporter wrote and painted on the printing paper with easily faded ink, ordinary watercolor pen and watercolor pigment, and then sprayed water on it with a sprinkler for watering flowers. In less than a minute, it can be clearly seen that the words written in faded ink have changed obviously, and the color has faded a lot, but it will take some time to disappear. Then, the reporter wrote on stationery and newspapers. However, what was written on the stationery did not disappear. Professor Dong explained: "Because the fibers used to make all kinds of paper are different, and the penetration degree of this ink is different from that of all kinds of paper, the fibers and ink of stationery like this have strong penetration, so it takes a long time." Next, I read the newspaper, and the result was greatly unexpected. The words in the newspaper disappeared as soon as they touched the water. Looking at the three pieces of paper together, the words written by Professor Dong in ink are almost invisible, but there are still some traces.

To this end, Professor Dong invented another kind of paper. In fact, there is nothing special about this kind of paper, except that ordinary paper is covered with a plastic film. Write on it with faded ink. After wiping with a wet cloth, there is no trace at all, and the trace on the cloth is gone with a gentle wipe.

Although this kind of ink can improve the utilization rate of waste paper, it will disappear if it gets wet, and it is not good if it is a roll paper for examination. In order to perfect this kind of ink, Professor Dong invented another kind of ink which is soluble in boiling water. Subsequently, the reporter started the experiment again.

There are two pots heating on the table. After the water boiled, the reporter put the ordinary printing paper into one pot and the ink paper invented by Professor Dong into another pot. The water temperature rises slowly. When the water temperature reaches 50℃, you can see that the ink characters have disappeared and the water has not changed, but the ordinary printing paper has not changed.

It's amazing! I hope this kind of ink can be widely used in our daily life in the future, which will greatly reduce the waste of paper.
