The history of industrial revolutions of the world (Part 3)

The fourth industrial revolution

In 2013, a new keyword “Industry 4.0” began to emerge from a German government report referring to this term to refer to high-tech strategy, computerization of manufacturing without the need of human involvement. This is called the digital revolution, through technologies such as the Internet of Things (IoT), artificial intelligence (AI), virtual reality (VR), virtual reality interaction (AR), social networks, cloud computing, mobile, big data analysis (SMAC)… to transform the entire real world into the digital world.

The fourth industrial revolution has had a strong impact on many fields, with the emergence of robots with artificial intelligence that have brought many applications in society. Thanks to AI technology, the more intelligent robots work, the ability to remember and learn immeasurably, while that ability in older people weakens.

In the field of Transportation, that unmanned vehicle system will develop thanks to the safety many times higher because there is no state of drunkenness, passing the red light, speeding over carelessly.

In August 2016, an American man using a Tesla self-driving car showed symptoms of chest pain. He promptly contacted his wife to call the hospital to notify the waiting doctor and then ordered the car to move to the hospital. Doctors gave emergency aid timely, saving this man.

In the field of health, the IBM Watson machine, nicknamed “The Doctor Who Knows”, can browse millions of medical records at the same time to provide doctors with evidence-based treatment options within few seconds thanks to its huge data aggregation capacity and powerful processing speed. This “knowledgeable doctor” also allows people to look up information about their health. Doctors only need to enter patient data to be analyzed, compare with the huge data available and give suggestions for the correct treatment.

In the field of Education, virtual reality technology will change the way of teaching and learning. Students can wear VR glasses and feel like sitting in a classroom listening to lectures, or immersive to witness simulated battles, see monuments, bring emotions and deep memories, help lessons learn more poignant.

Or when pilot training, students wear glasses and see the front is the cabin and learn to fly like a plane to practice to reduce risks during real flight. In the future, the number of virtual teachers may be much greater than the real teachers.

The fourth technological revolution promises to significantly develop in the near future.

The history of industrial revolutions of the world (Part 2)

The second industrial revolution

The second industrial revolution began in the late 19th century and lasted until the early 20th century. One of the remarkable features in the great industry is the mass production line – the principle of application of FWTaylor management (proposed in 1909, put into practice in 1913 – pioneer Ford).

Scientists have made great inventions on new production tools: computers, automatic machines and automatic machine systems, robots, automatic control systems. The inventors of this period also researched and created new materials such as polymers with high strength and heat resistance, widely used in life, and in industries.

During this time, new and endless sources of energy such as atomic energy, solar energy, wind energy, tidal energy, etc. were also found to replace the old ones.

Magical advances in transportation and communications such as giant supersonic aircraft, high-speed trains and other means of communication, radio broadcasting via artificial satellite systems, Magic achievements in the field of space conquest such as successfully launching the first artificial satellite of the earth, flying into space and setting foot on the moon are the achievements in the history of the Industrial Revolution. these two.

In addition, the green revolution in agriculture has made great progress in mechanization, irrigation, breeding methods, and pest control… helping many countries to overcome food shortage and hunger. prolonged.

The third industrial revolution

The third industrial revolution took place in the 1970s with the introduction of automated manufacturing based on computers, electronics and the Internet, creating a connected world.

The Third Industrial Revolution took place when advances in electronic infrastructure, computers and digitalization were triggered by the development of semiconductors, supercomputers (1960s), and computers. personal (1970s and 1980s) and the Internet (1990s).

By the end of the 20th century, this process was basically accomplished thanks to high-tech scientific achievements. Satellites, airplanes, computers, phones, Internet … are the technologies we now benefit from this revolution.

The history of industrial revolutions of the world (Part 1)

Talking about the industrial revolution is about the great change that it brings about in economic, cultural, and social fields.

Looking back at history, people have experienced many great scientific and technological revolutions. Each revolution is characterized by a change in the nature of production and this change is caused by the breakthroughs of science and technology.

Let’s look back at the history of industrial revolutions in the world!

The first industrial revolution

The world’s first industrial revolution began in England in the late 18th and early 19th centuries, starting with the mechanization of the textile industry. At that time, the textile factories had to be located near the river to take advantage of the running water, which caused inconvenience in many aspects.

In 1784, James Watt, an experimental assistant at a university, invented the steam engine. Thanks to this invention, the textile factory can be placed anywhere. This invention is considered to be the beginning of the mechanization process. In 1785, Father Edmund Cartwright produced an important invention in the textile industry, the loom. This machine has increased weaving productivity up to 40 times.

During this period, the metallurgical industry also made great strides. In 1784, Henry Cort found a way to practice “puddling” iron. Although the method of Henry Cort has refined the quality of iron, it still does not meet the requirements of the durability of the machine. In 1885, Henry Bessemer invented a blast furnace capable of smelting liquid iron into steel, overcoming the disadvantages of the previous machine.

The advance of the transportation industry was marked by the introduction of the first steam locomotive in 1804. By 1829, the train speed had reached 14 mph. This success has exploded rail systems in Europe and the US. In 1807, Robert Fulton built a steamboat to replace oars or sails.
