What inventions have improved people s lives in the last 10 to 15 years?

In the last 10 to 15 years, there have been many inventions that have improved people's lives. Some of the obvious examples include:

1.Mobile Internet: The popularity of smartphones and mobile Internet has enabled people to access information and use various applications anytime and anywhere, thus greatly improving the efficiency of people's lives.

2.High-speed rail: The popularity of high-speed rail has made it faster and more convenient for people to travel, reducing their travel time.

4.Autonomous driving technology: The development and trial of unmanned driving technology will completely change the way people travel and live.

5.3D printing technology: The popularity of 3D printing technology makes it more convenient for people to manufacture various items, and this technology is also widely used in medical, construction, automobile manufacturing and other fields.

In short, these inventions have improved people's lives in different ways, making people's lives more convenient, comfortable and colorful.

Over the past 10 to 15 years, high-speed rail has improved the way people get around because the increased speed has made it easier for people to get around. And there is also the widespread use of mobile phones. Make people's lives more convenient and colorful.

The most obvious invention is the mobile Internet.

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.

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.

There are many, such as cars, airplanes, high-speed rail.

High-speed rail, or high-speed rail for short, refers to a railway system with high design standards and can be used for safe high-speed travel of trains. The concept is not limited to tracks, nor does it refer to trains.

High-speed rail has different regulations in different countries, different times, and different scientific research and academic fields. The "Code for the Design of High-Speed Railways" issued by the State Railway Administration of China defines high-speed rail as a new passenger dedicated railway with a design speed of 250 kilometers per hour to 350 kilometers per hour and a standard gauge for EMU trains.

China's national *** defines China's high-speed rail as a new or existing line railway with a speed of 250 kilometers per hour and above, and promulgated the corresponding "Medium and Long-term Railway Network Planning" document, which includes some rail lines with a speed of 200 kilometers per hour into the scope of China's high-speed railway network.

Development history: On December 1, 2017, the "English Translation and Writing Specification in the Field of Public Service" was officially implemented, stipulating that the English name of the high-speed EMU standard is G-series high-speed On October 21, 2017, the "Advanced Rail Transit" key special 400km h transnational interconnection high-speed EMU rolled off the assembly line in CRRC Changchun Rail Passenger Car Co., Ltd.

By the end of 2020, the operating mileage of railways in China has reached 10,000 kilometers, including 10,000 kilometers of high-speed railways and 90,000 kilometers of railways in the central and western regions.

There are many of them, such as:

Air-conditioned car. Trains, airplanes, and more.

Much more. Let's say one: electric lights.

Iron birds flew all over the sky, broken iron boxes ran all over the ground, and people abandoned their houses and lived in collective caves.

It should be the Americans who invented something.

gunpowder,-- and so on. Too much. You buy an encyclopedia and take a look.

1973 Features: The volume is relatively small, and there are no functions such as this book and text messages Direct benefits to human life: easy to carry, conducive to communication The long-term impact on human life:

Develop various functions: file storage, photography, mp4

During the Second Industrial Revolution, airplanes and airplanes increasingly became indispensable carriers of modern civilization. It profoundly changes and impacts people's lives.

Every great invention of mankind will make a huge difference to humanity.

For example, the discovery of electricity, the invention of the electric light. The invention of the steam engine. There is also the invention of the computer and so on. ye

People invented computers, which allowed people to chat or look up information, etc.!

Computers, it makes our lives more convenient.

An invention that has brought about a huge change in human life: the electric light; The inventor was Edison;

The changes brought about by electric light: the conversion of electrical energy into light energy has greatly promoted the progress of human civilization, and the light can be seen at night.

Lighting electric light sources are generally divided into three categories: incandescent lamps, gas discharge lamps and other electric light sources.

Electric light is a device that converts electrical energy into light energy to provide illumination, which appeared in the second industrial revolution and works on the following principles:

When the current passes through the filament (tungsten filament, the melting point is more than 3000), the spiral filament continuously gathers the heat, so that the temperature of the filament reaches more than 2000, and the filament emits light when it is in an incandescent state, just like the red-hot iron can shine. The higher the temperature of the filament, the brighter the light emitted.

The three major inventions that changed the world, the last one that changed human life, is really eye-opening after reading.

The invention of electricity has changed people's habits of working at sunrise and resting at sunset. At the same time, its wide application makes it an indispensable part of daily life!

Electric lights make it possible to see clearly at night.

Cars make it easy to get around.

Electricity has changed people's habit of working at sunrise and sunset, and fans have cooled people in the summer.

Mobile phones are convenient for everyone to communicate.

Electric light bulbs, which bring light to people at night.
