The improvement of productivity is related to many things. For example, with today’s mobile phones, people can do many things with their smartphones, such as playing games, turning on the phone, and watching TV and mobile phones. In the past, PHS could only make calls, but now, with the development of the times, people will Save it for later use.

Social development, I have seen this before. In the past ten years when I was growing up, people began to become rich, and almost every family had a TV. I think whether the changes in life are benign or malignant depends on the development of decisions. People's birth photos show a father and son with simple functions such as answering calls and sending text messages. Since smartphone technology has been constantly changing our lifestyles. Take mobile phones as an example. The level of technology continues to improve, and technology has changed people. Fathers are surrounded by audiences in order to let their sons see the users. This is also related to the lifestyle of students after the development of science and technology.

These functions have changed people's lifestyles and enriched their lives. Nowadays, many things are becoming intelligent, and even household appliances can be turned on intelligently. People's lives are becoming more and more convenient.

Technology has changed people’s lives, but it has also brought a lot of troubles. The emergence of smartphones has made children poisoned by games on their phones. Many high-tech crimes have made it more difficult for the police to handle cases. The immaturity of some technologies has led to casualties, such as driverless cars hitting and killing people. These things tell us that technology is a double-edged sword.

Let’s take one of my personal experiences as an example. I got my first smartphone when I was in high school. This makes me, who has long wanted a cell phone, ecstatic. So, after I got my smartphone, I started playing games on it, and I became addicted. So I became addicted to games, which caused my eyesight to decline, my grades to decline, and I had no interest in studying. A smartphone, which was originally used to facilitate people's lives, became a hindrance to my life and affected my life in my hands. This is where people get into trouble when they use technology inappropriately.

Technology may bring trouble to others, but not all of it is trouble. In many cases, technology brings us a lot of help. If we use technology correctly and reasonably, then technology will be very helpful to us. Generally speaking, the advantages outweigh the disadvantages, but if the disadvantages are unavoidable and there are many, it is better to think about the correct way to use them.

The development of science and technology has indeed changed people's lives, but whether this change is benign or malignant depends on whether people use it properly. In this regard, I think we should use technology rationally to promote the healthy development of life. Avoid improper use and reduce the consequences of improper use.

Science is often very attractive Human beings, and science can never be exhausted and is always new and interesting. For example, take the experiment of floating eggs. Many people may know it, but the process of doing the experiment is far more novel than what they have heard.

The experiment is very simple. There are only four materials: a large glass, salt, a spoon, and eggs. Although it is simple, you can gain infinite knowledge from it.

First, I picked up the kettle and poured more than half a cup of water into the glass. Then I gently put the eggs into the water. After the eggs sank to the bottom of the cup, they stopped moving and seemed to be resting.

Then I put 1 spoonful of salt, but the egg didn't move; I started to put the second spoonful of salt, and the egg was still lying quietly at the bottom of the cup; I put 6 full spoonfuls of salt in one breath, and the egg didn't move. It did not live up to my expectations, and it rose a little; in the end, I refused to admit defeat and added 2 spoons of salt, and the egg rising index was higher.

I heard that other people’s eggs can float in the middle of water, so I took out the eggs and stirred the unmelted semi-finished salt water with a spoon. After the salt at the bottom of the cup had melted, I slowly added the eggs. When I went in, the egg kept floating up and down. I waited for a while, but the egg stopped moving and struggled to surface.

Finally, I poured the remaining 2 spoons of salt into the water, and the egg gradually rose to the water surface. It was like swimming freely with a swimming ring on. I naughtily pressed the egg down with my fingers and released my fingers. , the eggs quickly floated back to the water.

Why do eggs float? I learned from the computer: When the egg is first put into the water, because the specific gravity of the egg is greater than that of water, the buoyancy force on the egg is less than its own weight, so it will It sinks to the bottom; after adding salt, the water dissolves the salt, and the specific gravity of the water increases. When the specific gravity of the salt water is equal to the specific gravity of the egg, the egg will float in the middle of the water; continue to add salt, when the specific gravity of the salt water is greater than the egg. When the specific gravity is high, the egg will float on top of the salt water, with the top of the egg sticking out of the water.

The teacher told us in class: Any object in water will experience a buoyant force, and the magnitude of the buoyant force is equal to the weight of the volume of water displaced by the object. This is the famous "Archimedes' Law", also It's called the law of buoyancy. In fact, science is similar to the physics you need to learn when you grow up.

I was surprised that this small experiment actually contained such rich theorems. Only then did I understand that science is not only used for relaxation and fun, but also has a deep importance to us. I secretly made up my mind to study physics and study this interesting science in the days to come.

Eat more foods rich in vitamin A. Foods such as animal liver, carrots, tomatoes, sweet potatoes, spinach, pea shoots, etc. To protect your eyes, you can also work hard on your diet.
