Einstein is great and where

Einstein is great in:

1) Created the special theory of relativity, the general theory of relativity, etc.

2) The photonic hypothesis was proposed, which successfully explained the photoelectric effect.

3) Participate in anti-war peace movements.

In addition, Einstein's theories laid the theoretical foundation for the development of nuclear energy to help fight the Nazis.

In 1939, with the assistance of Leo Szilard and others, he sent a letter to Franklin D. Roosevelt in the United States.

directly contributed to the launch of the Manhattan Project, and World War II.

He later actively advocated peace, opposed the use of nuclear weapons, and signed the Russell-Einstein Declaration.

Albert Einstein ushered in a new era of modern science and technology and is widely regarded as the successor to Galileo.

The greatest physicist since Newton. In December 1999, Albert Einstein was named by Time Magazine

Selected as the "Great Man of the Century" of the 20th century.

What is Einstein's greatness? Who is greater, he or Newton?

He has made significant contributions to many fields of physics in academic research, and is the pioneer and dustpan of modern physics, and his theory of relativity is one of the major achievements of modern technology in the 20th century.

<> Einstein was one of the greatest physicists of the 20th century, and he made significant contributions to the development of modern physics. His research interests include relativity, quantum mechanics, statistical mechanics, and many other aspects, and his achievements have not only been widely recognized in the academic field, but also have had a profound impact in the social and cultural fields.

One of Einstein's most famous achievements is the theory of relativity. In 1905, he published his famous "Special Theory of Relativity"**, which introduced the basic concepts of relativity, the most famous of which is the formula e=mc. He successfully solved the problem of contradiction through the special theory of relativity, that is, the contradiction between the principle of invariance of the speed of light and Newtonian mechanics.

This achievement completely subverted the classic physics of Rolling Cave Town and led a new era of physics.

In addition, Einstein proposed the theory of "general relativity", which describes the interaction between matter and space, explains the phenomenon of gravity, and explains the existence of black holes and gravitational waves. These pre-fibrillation precautionary statements have been verified in later scientific practice and are one of the cornerstones of contemporary physics.

Another important achievement of Albert Einstein was his contribution to quantum mechanics. His research on quantum mechanics is simple and simple, he has proposed many thought experiments and questions, challenged the basic assumptions and theoretical foundations of quantum mechanics, and promoted the development of quantum mechanics.

In addition to physics, Einstein also worked on the social problems of mankind, such as war, etc. He was a staunch pacifist who had published many anti-war and egalitarian remarks and articles, which had a profound impact on the development of contemporary human society.

In conclusion, Albert Einstein was a great thinker and scientist, and his contributions in fields such as physics, philosophy, and sociology will always be remembered.

Albert Einstein invented:

1. Special relativity.

The special theory of relativity is a new theory of straight space-time proposed by Albert Einstein in 1905 entitled "On the Electrodynamics of Moving Bodies", which is different from Newton's view of space-time. "Narrow" means that it applies only to inertial frames of reference.

Special relativity includes not only a series of inferences such as time dilation, but also Maxwell's Hertzian equation transformation. Special relativity requires the use of mathematical tools that introduce tensors. Special relativity is an extension of Newton's theory of space-time, and to understand special relativity, it is necessary to understand four-dimensional space-time, which is mathematically formed as Minkowski geometric space.

2. General relativity.

General relativity is a theory that describes the gravitational interaction between matter. Its basis is AEinstein completed it in 1915 and officially published it in 1916.

This theory is the first to explain the gravitational field as a curvature of space-time.

Einstein's theory of general relativity has a very important application in astrophysics: it directly deduces that some massive stars will end up as a black hole—certain regions of space-time are so distorted that even light cannot escape; The amount of mass that a star will collapse into a black hole is the work of the Indian-born physicist Chandrasekhar – the Chandrasekhar limit (the upper mass limit of a white dwarf).

3. Photoelectric effect.

The photoelectric effect is an important and magical phenomenon in physics. Under the irradiation of electromagnetic waves higher than a certain frequency, the electrons inside some substances will be excited by photons to form an electric current, that is, photogenerated electricity. The photoelectric phenomenon was discovered by the German physicist Hertz in 1887, and the correct explanation was proposed by Albert Einstein.

In the process of studying the photoelectric effect, physicists have gained a deeper understanding of the quantum properties of photons, which has a significant impact on the concept of wave-particle duality.

4. Conservation of energy.

Conservation of energy, is a term in physics. Energy is neither created nor disappeared out of thin air, it can only be transferred from one object to another, and the forms of energy can also be converted into each other. This is how people summarize energy, which is called the law of conservation of energy.

It was discovered independently in 5 countries by more than 10 scientists from different professions. Among them, Meyer, Joule, and Helmholtz were the main contributors. It is one of the most basic laws in natural science, which scientifically elucidates the idea of the immortality of motion.

5. The cosmological constant.

In 1917, Albert Einstein used his gravitational field equation to investigate the universe as a whole. In order to explain the existence of a static universe with a non-zero density of matter, he introduced a term proportional to the gauge tensor into the field equation, which was represented by symbols. This scale constant is small and negligible at the galactic scale.

It can only be meaningful on a cosmic scale, so it's called a cosmological constant.

1. Smoke detector.

Due to the nucleus of americium.

Unstable, once cracked, the mass seems to disappear somewhat, because the mass of the fragment is smaller than the original nucleus. In fact, the mass of the americium atom does not disappear at all. This is what Albert Einstein told us.

2. Flat roads.

In Einstein's Ph.D., he developed a new method for measuring molecules in different solutions, which later became the basic methods of colloidal chemistry. Building materials engineers use his research when building roads.

3. Computer monitors.

In a short split second, electrons are emitted from the cathode of the picture tube, as if they have gained energy during the gallop and accumulated on the display——— which is exactly in line with Einstein's special theory of relativity.

The engineer who invented the computer monitor had to make the display conform to the "relativistic effect", otherwise the magnet that controls the electronic gallop will produce a blurry image on the display, making it impossible for you to work, of course, a wonderful computer game.

I can't play anymore.

4. Precise laser.

The barcode of each item.

Thanks to Einstein's laser theory, only a laser can accurately read the code in a barcode.

5. Solar cells.

Photocells can convert solar energy into electricity, and Einstein correctly analyzed this conversion principle for the first time in an article published 90 years ago.

He discovered that photons have energy. Certain photons carry enough energy to overcome the "stickiness" that concentrates electrons on a certain metal, which is known as the photoelectric effect.

6. Digital camera.

Photons flying in from the lens squeeze electrons out of the semiconductor, which also makes use of the valuable photoelectric effect. <

7. Medications. Many drugs are made thanks to Einstein's article on Brownian motion.

Target**. The British botanist Robert Brown was the first to observe that the particles in a suspended liquid are forever moving in random motion. Albert Einstein used Brownian motion to create a statistical method that linked micro and macro quantities.

8. Global Positioning System.

GPS (Global Positioning System) can help you get in touch with searchers. Albert Einstein discovered 100 years ago that the traditional concept of time is not sufficient if you want to think about multiple events in different places together.

It is no exaggeration to say that the inventions derived from the scientific theories created by Einstein cover almost every corner of modern civilization. Computer games, buses, digital cameras, ......Every detail of our food, clothing, housing and transportation has the shadow of Einstein.

Since I was a child, I have admired Einstein the most, not only because Einstein occupies a very important place in the scientific community, but I think that Einstein's spirit touches me very much. Our teachers often tell us this story of Albert Einstein, letting us know that to be a human being, we must use ourselves as a mirror, and correct our mistakes and correct our mistakes: Einstein was very playful when he was a child.

His mother repeatedly told him, "You can't go on like this." Albert Einstein always said disappreciatively

"Look at my friends, aren't they all the same as me?" "One day, my father told Einstein an interesting story. Father said:

Yesterday, my neighbor, Uncle Jack, and I went to clean a large chimney in the factory to the south. The chimney can only be climbed up from the chimney by stepping on a steel ladder. Your Uncle Jack is in the front, and I'm in the back.

We grabbed the steel ladder and finally climbed it step by step. When I came down, your Uncle Jack was still in front, and I was behind. Coming out of the chimney, I saw your Uncle Jack, and thought to myself that I must be as wizened as he was, and my face was as dirty as a clown, so I went to the nearby creek and washed and washed it.

As for your Uncle Jack, when he saw that my face was clean, he thought he was as clean as I was, so he just washed his hands and went out into the street. As a result, the people on the street laughed and their stomachs hurt, and they thought that your Uncle Jack was a madman. "Father solemnly said to Einstein

In fact, no one else can be your mirror, only yourself is your own mirror. If you use someone else as a mirror, you may be looking like a genius. When Einstein heard this, his face was full of shame, and he left the naughty children.

He always used himself as a mirror to examine and reflect himself, and finally reflected the sparkle of his life.

Albert Einstein is a great man, the person I admire the most, and I want to be the second Einstein in the world, or even more outstanding than Einstein!
