1 Solar cells, burglar alarms, and light meters for cameras are all based on the photoelectric effect.
2 Nuclear energy makes use of the physical phenomenon that when uranium atoms are fissioned, a small loss of total mass can be converted into energy, based on Einstein's famous equation e mc2. Today, nuclear energy provides 25 percent of the UK's electricity.
3 The Global Positioning System (GPS) is able to accurately position objects down to the meter because of the correction of signals emitted by Earth satellites based on Einstein's theory of relativity.
4 Special relativity, combined with quantum theory, points to the existence of antimatter. Scientists use positrons, or antimatter "electrons," to study brain activity through X-ray tomography.
5 The properties of subatomic particles are a direct result of the theory of relativity, and their existence can explain a variety of phenomena ranging from the properties of chemical elements to the action of magnets.
6 Einstein's research on photons in 1916-1917 laid the groundwork for the discovery of lasers 40 years later. At present, lasers are widely used in a variety of products from *** to laser printers.

1. Digital cameras: Photons flying in from the lens will squeeze the electrons in the semiconductor, which also makes use of the valuable Einstein photoelectric effect.
2. Flat Highway: 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 engineers who invented the computer monitors must make the display conform to the "relativistic effect", otherwise the magnet that controls the electronic gallop will produce a blurry image on the display.
4. Accurate laser: The barcode of each product also benefits from Einstein's laser theory, and only the laser can accurately read the code in the barcode.
5. Solar cells: These photocells can convert solar energy into electrical energy, 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.

Albert Einstein was a scientist, not an inventor. Albert Einstein was one of the most creative and intelligent figures in human history. He pioneered four areas of physics during his lifetime:
Special relativity, general relativity, cosmology, and unified field theory. He is one of the main founders of quantum theory and has also made significant contributions to the theory of molecular motion and the theory of quantum statistics. He proposed theories such as special and general relativity, the quantum hypothesis of light, conservation of energy, and the cosmological constant.
Albert Einstein was born on March 14, 1879 in Ulm, Germany. Einstein graduated from the Swiss Federal Institute of Technology in Zurich in 1900 and later worked as a technician at the Swiss Patent Office in Bern. In 1909 he became professor of theoretical physics at the University of Zurich.
In 1933, Einstein left Germany and moved to the United States, where he worked at the Institute for Advanced Study in Princeton. Albert Einstein died on April 18, 1955, in Princeton, New Jersey, at the age of 76.
Albert Einstein was the greatest scientist and thinker of the 20th century. His scientific and philosophical ideas (philosophy of science, philosophy of society, philosophy of life) are quite insightful and extraordinary. Einstein's contribution to modern physics is unparalleled, and throughout his scientific career, he has always pursued the universal, immutable laws of physics.
His theories cover all the fundamental questions of nature, from the universe to subatomic particles. He revised the traditional concepts of time and space, energy and matter. His theory of relativity not only impacted the theoretical system of classical physics since Newton, but also changed the traditional concepts of space and time.
Albert Einstein ushered in a new era of modern science and technology and is widely regarded as the greatest physicist since Galileo.

Einstein did not have physical inventions, and his main achievements were theories, such as: special relativity, general relativity, the quantum hypothesis of light, cosmology, and unified field theory. In addition, he has also made significant contributions to the theory of molecular motion and quantum statistics.
Albert Einstein won the Nobel Prize in Physics and is widely regarded as the greatest physicist after Galileo and Newton.
In 1905, Einstein's photon hypothesis successfully explained the photoelectric effect, for which he was awarded the Nobel Prize in Physics in 1921. The phenomenon of light shining on a metal and causing a change in the electrical properties of a substance is collectively known as the photoelectric effect.
The photoelectric effect can be divided into photoelectron emission, photoconductive effect, and photogenerated volt effect. The phenomenon of photoelectron emission occurs on the surface of an object, also known as the external photoelectric effect. The latter two phenomena occur inside the object and are known as the internal photoelectric effect.
It is generally believed that the electric light was created by American Thomas Alva Edison. >>>More

Einstein was not smart, he just tapped out more of his latent IQ, and more was only relative, he only mined about one-third of his IQ, which means that we can all become more successful than Einstein!
Theoretical physicists, nothing invented. But he changed humanity's perception of the universe, time, space, energy, and mass. Called the greatest scientist of the 20th century.
In the second half of his life, Einstein devoted himself to the search for a unified theory, the unified field theory, known as the twenty scientific mysteries of the twentieth century, in an attempt to unify the various interacting forces in nature, such as electromagnetism, gravity, weakness, and strength, but this work was unsuccessful. >>>More
