The difference between the rich and the poor in the world is a thought difference! Therefore, the greatest invention and creation of the 21st century is not the computer or the Internet, but what kind of life people have! Through their own honest efforts, people can realize their dreams, which is the biggest invention in the world in the 21st century!
The poorest people in the world are not people who have no money, but people who have no dreams. So, you have to think about three things: What do you really want?
What can you do? What should you do?
Mr. DeVos is one of the nation's top three speakers, and his many cautionary tales have inspired thousands of people around the world to succeed. Three of these sentences are shared with you:1
What exactly do you want? 2.What can you do?
3.What are you doing now? Many people have been busy all their lives, working hard all their lives, achieving nothing, and repaying their grievances for a lifetime.
Why? Because they can't figure out these three things, some people know three things, but the order is reversed. Many friends have never thought about what to get in their lives, how can you put in real effort for things that you haven't thought about. Sometimes, we invite some new friends:
Let's listen to the class! Don't listen to it. Are you satisfied with your current income?
Make do with it! How is your current life? Make do with it!
Our friends love to save money, make revolutions, and be diligent and thrifty, but I tell you today: wealth is not saved! It's earned!
Many children from poor families work hard to study, and there is nothing wrong with that! It's a good thing to love to learn, but people who can really read are in good shape. For those who really don't read in vain, you will see a career development trend.
What is the purpose of reading? In order to get a diploma, in order to find a job, in order to earn more money. Today I tell you that one of the most important ideas in the United States is:
Earn money with a diploma, and earn a small amount of money; Earn money by physical strength, and earn dead money. Earn money by relying on academic qualifications, no matter how good a doctorate is, you are working for others, earning a small amount of money; And friends who rely on physical strength to earn money, you are more dangerous today, physical strength is in you to earn money, no physical strength, no health, you can't earn money!
If you do your job today, you will have it, and if you don't do it, you will not have it, it is too dangerous! We have seen many, many millionaires, multimillionaires, billionaires in the United States, they are not necessarily smarter than us, they are not necessarily more educated than us, why do they earn several times, hundreds of times, hundreds of thousands of times more than us in an hour! Why?
It's because the idea is different!

The science and technology of the 20th century also created television, nylon, and plastics, which greatly changed people's lives.
1. TV. The birth of television is one of the greatest inventions of mankind in the 20th century. In modern society, life without television is no longer conceivable.
Black-and-white and color TVs of all models and functions are miraculously and rapidly changing people's lives from assembly lines to factories, schools, hospitals, and homes around the world.
2. Nylon. Carothers, an American organic chemist, made a polymer from adipic acid and hexamethylenediamine in 1935, which was called polymer 66 at that time because these two components contained 6 carbon atoms. He melted the polymer and pressed it out with an injection needle, where it was stretched under tension called a fiber.
This fiber, polyamide 66 fiber, was named nylon after industrialization in 1939, and it was the earliest synthetic fiber variety to achieve industrialization.
3. Plastics. In the 60s of the 19th century, due to the shortage of ivory in the United States, the lack of raw materials for the manufacture of billiard calendar sailing wheels, in 1869, the earliest artificially manufactured plastic celluloid obtained a limb letter patent. Although celluloid is the earliest artificially manufactured plastic, it is a man-made plastic, not a synthetic plastic, the first synthetic plastic is a phenolic resin heating mold, which was made in the early 20th century, in 1910 by the American-Belgian chemist Beckland.
The significance of the invention of plastics
Plastic products are too common around us, you need plastic bags when you go to the supermarket to buy things, the packaging bags of snacks are also plastic, the crisper boxes you use to put food are also plastic products, and the silicone you use for smartphones, household appliances, cars, and even breast augmentation all contain plastic materials.
Plastic alone has saved the lives of countless elephants, so many environmentalists have no reason to hate plastic products, not because plastic pollutes the environment, but humans pollute the environment.
Plastic has also left valuable audio-visual materials for our human history, in the past, it was difficult for us human beings to leave any ** information except painting, and those who could afford to hire painters were rich, and the poor naturally could not leave anything.

In fact, in the middle and late 21st century, when the machining accuracy reached the picometer stage, people would think that the 21st century was the picometer century.
The benefits of nanotechnology are as follows:
1. The essential function of nanotechnology is to directly use atoms or molecules to construct products with specific functions. That is, nano-sized structures are artificially formed through nano-precision processing.
2. The research and application of nanotechnology are mainly in Yuyou materials and preparation, microelectronics and computer technology, medicine and health, aerospace and aviation, environment and energy, biotechnology and agricultural products.
3. The equipment made of nano materials is lighter in weight, stronger in hardness, longer in life, lower in maintenance cost and more convenient in design. The use of nanomaterials can also make materials with specific properties or materials that do not exist in nature, and make biomaterials and biomimetic materials.
Nanotechnology Applications:
1. When clothes meet nanotechnology.
Due to the physical characteristics of nanomaterials, such as small size, they can form a uniform, extremely thin thickness and small gap "fog-like" protective layer on the surface of the cloth, which makes the clothes have the function of isolating oil droplets, dust, stains, bacteria, etc., and plays a very good protective role. At the same time, the material of the clothing fabric using nanotechnology is very thin, and it hardly changes the physical properties of the original fabric, such as color, comfort, and breathability.
2. When the residence meets nanotechnology.
Nanotechnology and nano materials can improve the washing resistance of wall coatings by about ten times, and the nano thin layer has a protective effect, which can block stains such as water droplets and oil droplets greater than 100nm at room temperature, and has the function of protecting the wall of Qinghuai. When glass and tiles are coated with a nano-thin layer, there are no dirt such as dust, water droplets, and oil droplets on the surface, so that the glass and tiles do not need to be scrubbed frequently.
3. When travel meets nanotechnology.
Nowadays, most vehicles are inseparable from engines, such as automobiles, ships, airplanes, etc. Nanomaterials change people's travel, mainly because nanomaterials can greatly improve the efficiency, working life and reliability of the engine, and then improve and improve the performance indicators of vehicles. <>

Five major inventions that have affected human life in the 21st century: 1. Repair gloves 2. Bionic heart 3. Neurotransformation 4. Neurotransformation 5. Seeing the world with ears.
In the 21st century, many surprising technological innovations will have a significant impact on the daily lives of human beings. The scientist who won the 2004 Eureka Inspirational Science Award for his "Repair Gloves" declared that the prophecy of science fiction ** is not far from becoming a reality.
Repair gloves. A "prosthetic glove" is a device implanted with special actuators and sensors that mimic the biomechanics of the human hand. The Robotic Research Laboratory designed the "Repair Gloves" with the aim of creating a "coat" with artificial muscles. This "coat" helps the body to re-move.
Scientists, programmers, and inventors around the world are developing innovative technologies that replicate, replace, or help the human body.
Bionic heart. The Homotope Transplant Artificial Heart CATO is a device that fully mimics the human heart, consisting of blood chambers, ventricles, valves, and special actuation devices that draw blood into the pulmonary arteries and aorta.
The biggest challenge for scientists is to transplant an artificial heart device, including a power supply, into the confined space where the heart would normally be located. Scientists have experimented with cows with great success, which has also created favorable conditions for him to successfully apply for a patent for the same transplant of artificial heart.
Neurotransformation. An Australian programmer developed a system. Under this system, people suffering from amyotrophic lateral sclerosis can no longer be limited by their own disabilities and can communicate with others through nerve cues. Another scientist has developed a new type of human-machine interface:
A person can use ** surface electrodes to receive nerve signals, and then after artificial intelligence analysis, they can achieve the purpose of communication. When the two scientists collaborated, the system became known as Neurotranslational Technology.
Ears see the world.
Dr. Leslie Kay designed a sonar device that emits ultrasound waves and can also detect reflections from other objects and obstacles. The data is then converted into a series of audible sounds that correspond in frequency to those emitted by distant objects. With a little training, the human brain seems to be able to subconsciously translate these sounds into spatial imaginations.
This technology won the 1998 World Communications Innovation Award, and today blind people around the world will use this technology to confidently walk in areas they are not familiar with.
Artificial muscles. Work on artificial muscles began in the 40s of the last century, but it is only in the last 10 years that a significant development has been made, as research centers around the world have developed specialized polymers and smart materials. In the future, there is a good chance that humanity will see the strongest man in the world compete with the most powerful bionic arm.

With the reform of the economic system, the competitive pressure, failures and setbacks experienced by members of society will be unprecedentedly aggravated. The rapid development of science and technology has caused a large gap between some members of society who lack basic education and those who enjoy a good education in many aspects, and eventually there will be a sharp differentiation of income, and both the poor and the rich will bear tremendous psychological pressure. The Chinese people understand the necessary psychological knowledge, which has increasingly become the necessary common sense knowledge for healthy members, which is conducive to resolving the potential huge hidden dangers in their hearts and protecting a good state of mind. The benefits range from personal development to social stability. >>>More
