The end of the 19th century was a period of change in physics, and Einstein made a fundamental breakthrough in theory by starting from experimental facts, examining the basic concepts of physics from a new perspective. Some of his achievements gave a significant boost to astronomy. His quantum theories have had a great influence on astrophysics, especially theoretical astrophysics.
The first full-fledged aspect of theoretical astrophysics, the theory of stellar atmospheres, was built on the basis of quantum theory and radiation theory. Einstein's special theory of relativity succeeded in revealing the relationship between energy and mass, solving the long-standing conundrum of stellar energy**. In recent years, more and more high-energy physical phenomena have been discovered, and special relativity has become one of the most basic theoretical tools to explain this phenomenon.
Its general theory of relativity also solved a mystery in astronomy for many years, and deduced the phenomenon of bending light that was later verified, and became the theoretical basis for many later astronomical concepts.
Einstein's greatest contribution to astronomy was his cosmological theory. He founded relativistic cosmology, established a statically finite and boundless self-consistent dynamic model of the universe, and introduced new concepts such as cosmological principles and curved space, which greatly promoted the development of modern astronomy.
He won the Nobel Prize in Physics in 1921, but not because of the great achievement of relativity, but because of quantum theory, because when he proposed the theory of relativity, almost all scientists thought it was a fallacy, and later it turned out that the theory of relativity was a great discovery, and when several years had passed, in order to compensate, the Jury Society awarded him the Nobel Prize for his achievements in quantum theory.

How much did Einstein contribute to humanity? How much of an impact does he have on our lives?
-
There is no greater impact on our lives than the increase in electricity generation (because his theories led to the discovery and application of nuclear technology).
-
The idea and the application of his theories to the exploration of the universe is what drives us.

1. Smoke detector.
2. Flat roads.
In Einstein's Ph.D., new methods for measuring molecules in different solutions were introduced, and these methods later became the basic methods of colloidal chemistry. Building materials engineers use his research when building roads.
3. Computer monitors.
The engineer who invented the computer monitor had to conform to the "relativistic effect" of the display, or the magnet that controls the electronic gallop would produce a blurry image on the display.
4. Precise laser.
The barcode of each item also benefits from Einstein's laser theory, and only a laser can accurately read the code in the barcode.
5. Solar cells.
These photocells are capable of converting 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, also taking advantage of the valuable Einstein 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.
To this day, these statistics are the dosing rules that pharmacists around the world must follow.
8. Global Positioning System.
Albert Einstein found that the traditional concept of time was insufficient if multiple events in different places were to be considered together. Although precise atomic clocks are installed on GPS satellites, if there is no time-adjusting of the atomic clock from the ground to the satellite's atomic clock, the signals sent by the positioning system to the ground will be off by kilometres every day.
9. Control the energy of X-rays.
Your doctor is radiating to you**.
, you need to estimate the damage that X-rays may cause to your cells, based on Einstein's e=mc2.

Albert Einstein: He discovered the microscopic laws that subverted the world of physics. Thus, people began to invent and create modernization.
The year 1905 was a miracle year not only for Einstein, who was only 26 years old at the time, but also for the entire history of physics. In that year, Albert Einstein proposed three epoch-making theories – the quantum hypothesis of light (for which he won the 1921 Nobel Prize), the special theory of relativity, and the statistical explanation of Brownian motion (the results of the confirmatory experiments that led to the conversion of several great scientists who did not believe that atoms were real at the time).
For the next 11 years, Einstein focused on his higher goal, general relativity, and finally gave the basic framework of general relativity at the age of 37. For many years after that, he perfected this theory, made specific calculations (the system of nonlinear partial differential equations of general relativity is extremely difficult to solve, and to this day, many physicists and even mathematicians are still studying its solution problems), and applied it to the entire universe. Cosmology in the modern sense was pioneered by Albert Einstein.
It is no exaggeration to say that the inventions and creations derived from the scientific theories founded 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.
Smoke detector.
Here is a hypothetical "you" as an analogy. In the morning, when you wake up from your hotel and step out of your room to get ready for your morning exercise, pay attention to the smoke detectors on your head. It uses the radioactive material americium-241 to release energy to produce a small bundle of charged particles.
In the event of an accident, the smoke coming out of the flame reacts with the particle beam, triggering the alarm to sound automatically.
Since the nucleus of americium is unstable, once it splits, the mass seems to disappear somewhat, as the mass of the fragments is smaller than the original nucleus.

Albert Einstein said that success is 99 percent perspiration plus one percent genius. The complete sentence is that success is 99 percent perspiration plus 1 percent genius. However, usually 1 percent genius is more important than 99 percent sweat.
Original English text, geniusisonepercentinspiration, ninetyninepercentperspiration.
Overview of Albert EinsteinAlbert Einstein was born in Ulm, Württemberg, Germany, and graduated from the University of Zurich as a physicist of Jewish descent. Albert Einstein laid the theoretical foundation for the development of nuclear energy and ushered in a new era of modern science and technology, and is widely regarded as the greatest physicist since Galileo and Newton.
Einstein was a genius, and he believed in genius, and he had a conditional attitude of recognition of genius. Einstein acknowledged hard work, but in the final analysis, he valued inspiration more, and he believed that people cannot live without innate inspiration and cannot be without acquired education.

Albert Einstein was a world-famous German-American scientist and the founder and founder of modern physics. Einstein graduated from the Technical University of Zurich in 1900 and began teaching at the university in 1909, becoming director of the Royal Wilhelm Institute of Physics and professor at the University of Berlin in 1914. He was forced to move to the United States and became a naturalized American citizen in 1940.
Albert Einstein was not only a great scientist, an outstanding thinker with a spirit of philosophical inquiry, but also an upright person with a high sense of social responsibility. He lived in Germany and the United States, the epicenter of the Western political maelstrom, and lived through two world wars. He profoundly realized what kind of impact the fruits of a scientist's labor will have on society, and what kind of responsibility an intellectual should bear to society.

Einstein used this as a breakthrough to boldly propose the famous equivalence principle on the basis of two rounds of equal mass: a non-inertial frame with an acceleration of a is equivalent to an inertial frame with a uniform gravitational field. In other words, the motion seen by an acceleration system is exactly the same as that seen by a nucleus-making inertial system with a gravitational field. >>>More
