What changes inventions and creations have brought to our lives

Hello, make our life better and better.

Inventions in life:

1. According to the principle of the bat ultrasonic locator, people also imitate the "pathfinder" used by the blind, which is equipped with an ultrasonic transmitter, and the blind can use it to find the people on the poles, steps, bridges, etc. Today, "ultrasound glasses" with a similar effect have also been made.

2. The incomplete photosynthesizer that simulates cyanobacteria will be designed to design a bionic photolysis device, so that a large amount of hydrogen can be obtained.

3. According to the research on the human bone muscular system and bioelectric control, a human enhancement device - walking machine has been imitated.

4. The hooks of modern cranes originated from the paws of many animals.

Significance of the invention:

Invention is the starting point of technology and production activities, and with the invention and application of stone tools and artificial fire, the history of human material production and social life began. Technological change and technological progress, the improvement of productive forces and people's living standards, and the development of social history are all inseparable from invention and creation. The progress of ancient society relied on inventions such as the grinding of stone tools, the smelting of copper and iron, the making of pottery and drying bricks, and the cultivation of silkworms and silk.

The industrial revolution of the 18th century began with the invention of new textile machines and steam engines. Electronic computers and a series of modern inventions have fundamentally changed people's working methods, living conditions, and social outlook. The history of human civilization is, first and foremost, a history of invention and creation.

The saw was invented based on sawgrass. The aircraft balancer was invented based on the wings of a dragonfly.

The needs of life, the increase in productivity. The classic saying is that the adventurer invented the airplane, and the pessimist invented the parachute.

Inventions have changed our lives, such as mobile phones, which allow people to communicate and talk remotely.

(Topic 1) Please start from the needs of people's lives, what other products can we improve and invent? Write down your vision.

Smart insect traps can be invented to give you a good night's sleep in the summer.

Giant plant seeds .........Wait a minute.

Scientific and technological inventions have brought many positive effects to human production and poor life. First of all, scientific and technological inventions have greatly improved social productive forces, promoted the harmonious development of society, and made the country more prosperous, rich and strong, and the people more prosperous and happy. Secondly, scientific and technological inventions have promoted the development of human civilization, improved people's living standards and quality of life, and improved people's living environment.

In addition, scientific and technological inventions have also promoted economic and social development and improved material quality. But at the same time, scientific and technological inventions may also bring some negative effects, such as damage to the environment, over-exploitation of resources, etc. Therefore, in the process of leveraging technological inventions, we need to weigh the pros and cons and make informed decisions.

1.It has greatly improved social productivity.

2.It has promoted the harmonious development of the stool society. 3.Promoted human civilization.

development. 4.It has improved the living standards and quality of life of people with jujube liquid.

5.It has promoted economic and social development and improved material quality. 6.

Make the country more prosperous, rich and strong, the people more prosperous, and happy The development of science and technology is still there.

1.Internet. In the early days, many people looked down on the Internet, thinking that it was just a toy with no practical use. But now the Internet has penetrated into all walks of life, profoundly changed the way people live and work, and has become an indispensable infrastructure.

2.Mobile payments. In the early days, many people were skeptical of mobile payments, feeling that they were not safe or convenient.

However, with the development and application of technology, mobile payment has become a mainstream payment method, which brings great convenience to people's consumption life, especially during the epidemic, which has played an important role and become an indispensable means of payment in people's lives.

3.Socializing**. Social networks were skeptical in the early days, but while they changed the way people communicate and communicate, they also affected socio-cultural and business models.

Social networking has become an important information and communication platform for people's work and life, and all walks of life in society are actively using and adapting to this new society.

4.**Educate. Online education also faced many doubts at first, but it has been widely used under the catalysis of the epidemic, which has realized the remoteness and personalization of knowledge dissemination, and changed people's learning methods and concepts.

This form of education not only meets the learning needs but also cultivates the motivation for social progress and development, and has become an important part of people's learning and life.

Therefore, driven by technological development and social application, many things that were looked down upon or questioned in the early stage can gradually develop and profoundly affect people's lives, and become an important part of people's inseparable. This also proves once again that the influence of any technology or concept needs time to accumulate and be verified by society, and the initial doubts should not become an obstacle to development. Rather than criticizing overnight, it is better to give opportunities and support, which is also the driving force for social progress.

1. Papermaking.

In the first year of the Eastern Han Dynasty and Emperor Yuanxing (105 AD), Cai Lun used tree bark, broken fishing nets, rags, and hemp covers as raw materials on the basis of summarizing the experience of his predecessors in making silk weaving crystals.

It was made of plant fiber paper suitable for writing, and the papermaking technology was improved, so that paper became a commonly used writing material. It is known as "Caihou paper".

Second, the compass.

A compass is a simple instrument used to determine directions. Formerly known as Sinan. The main component is a magnetic needle mounted on a shaft that can be rotated freely. The magnetic needle can remain in the tangent direction of the magnetic meridian under the action of the geomagnetic field.

The north pole of the magnetic needle points to the south pole of the geography, and the direction can be discerned by using this property. The Oak Hall is often used for navigation, geodesy, travel, and military purposes.

3. Gunpowder. Gunpowder is a black or brown explosive, mechanically mixed with potassium nitrate, charcoal and sulfur, initially in powder form, and later generally made into granules of different sizes, which can be used for different purposes, and has been used as the only military propellant before the introduction of smokeless gunpowder.

Four things such as fiction, printing.

Printing is reported to have been invented by Bi Sheng during the Northern Song Dynasty, which is considered to be the world's earliest movable type printing technology.
