How many inventions did Einstein have in his lifetime?

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.

Special relativity, general relativity, cosmology, thermodynamic equations (similar to Gibbs's free energy equation and discovered independently of Gibbs at about the same time), statistical physics (a method for determining the size of molecules, which led to the bankruptcy of anti-atomism), the optical quantum hypothesis (for which he was awarded the Nobel Prize in Physics in 1921), Bose-Einstein condensation, laser theory, unified field theory (unfinished), nuclear physics (based on the mass-energy equation in special relativity)

He was not an inventor, he was a famous physicist, and the theory of relativity was the doctrine he proposed.

Einstein didn't have many inventions, but he had a lot of theories.

The light meter for batteries, burglar alarms, and cameras is 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.

I don't know, how many.

Einstein was not an inventor, he did not invent specific things, but his discoveries and theories guided future generations to complete many inventions that could change the course of history.

Albert Einstein created the special theory of relativity in 1905 and the general theory of relativity in 1915.

In 1905, Einstein put forward the quantum hypothesis of light to solve the problem of the photoelectric effect, Einstein clarified the essence of the law of immortality of matter and the law of conservation of energy from a newer height, pointed out the close relationship between the two laws, and deepened the understanding of nature by human beings.

When Einstein proposed the theory of relativity, he introduced the cosmological constant (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 gravitational field equation, which was represented by symbols. ）

Introduction to Albert Einstein

Albert Einstein was born into a Jewish family in Ulm, Germany, to Jewish parents. He graduated from ETH Zurich in 1900 and became a Swiss citizen.

In 1905, Albert Einstein received a doctorate in physics from the University of Zurich and developed the photon hypothesis and successfully explained the photoelectric effect (for which he was awarded the Nobel Prize in Physics in 1921).

In the same year, he founded the special theory of relativity, in 1915 he founded the general theory of relativity, in 1933 he moved to the United States, where he worked at the Institute for Advanced Study in Princeton, and in 1940 he became an American citizen while retaining Swiss citizenship. On April 18, 1955, Albert Einstein died in Princeton, New Jersey, USA, at the age of 76.

Einstein made four epoch-making contributions to science during his lifetime.

First, the quantum hypothesis of light was proposed, which unified the wave and particle properties of light, and opened up a new era for human beings to understand the wave-particle duality of the material world.

Second, it completed the theoretical explanation of Brownian motion and the specific method of determining the size of molecules, and completely refuted the erroneous trend of thought that negated the theory of atoms and molecules.

Sanzao founded the special theory of relativity, overturned Newton's absolute view of time and space, and pointed out that time and space are relative, that is, the length of space, the speed of time, and the magnitude of mass in an inertial system will change with the speed of motion of the object, thus causing a great change in the theoretical basis of physics.

Fourth, starting from the equivalence of gravitational mass and inertial mass, the general theory of relativity was established. Space and time cannot exist independently of matter, the structure and properties of space depend on the distribution of matter, and the gravitational attraction between matter is just a manifestation of the curvature of space, revealing the unity of space-time and matter as a unity of time and space.

He is a scientist, not an inventor. Albert Einstein (1879-1955) was a German-American physicist, thinker, and philosopher, and Jewish. He is the founder and founder of modern physics, the proposer of the "mass-energy relation" of the theory of relativity, and the defender of the "interpretation of deterministic quantum mechanics".

On December 26, 1999, Albert Einstein was selected as a "Great Man of the Century" by Time Magazine.

Only by virtue of it, discoveries, and inventions appear.

Albert Einstein invented these things:

1. Smoke detector.

2. Smooth the highway in front of the road.

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.

Albert Einstein was born in Ulm, Württemberg, Germany, and graduated from ETH Zurich as a physicist of Jewish descent. He mainly invented:

Relativity. The theory of relativity gives the law of motion of an object in high-speed motion, suggests that mass is equivalent to energy, and gives the mass-energy relation. These two results are not obvious for low-speed moving macroscopic objects, but they show extreme importance in the study of microscopic particles.

Because the speed of microscopic particles is generally relatively fast, some close to or even reaching the speed of light, the physics of particles is inseparable from the theory of relativity. The mass-energy relationship not only creates the necessary conditions for the establishment and development of quantum theory, but also provides a basis for the development and application of nuclear physics.

Conservation of energy. According to Einstein, the mass of matter is a measure of inertia, and energy is a measure of the motion of the Huirang bond; Energy and mass are not isolated from each other, but are interconnected and inseparable. The change of the mass of the object will cause the energy to change accordingly; The change of the energy of the object will also cause a corresponding change in the mass.

From the height of renewal, Einstein clarified the essence of the law of the immortality of matter and the law of conservation of energy, and pointed out the close relationship between the two laws, which made mankind's understanding of nature one step deeper.

Photoelectric effect. In 1905, Einstein proposed the photon hypothesis, and was the first to successfully explain the photoelectric effect, that is, the effect of emitting electrons from metal surfaces under light irradiation, and the emitted electrons are called photoelectrons;

Einstein's discovery opened the door to quantum physics, and Einstein was awarded the Nobel Prize in Physics in 1921 for "his achievements in theoretical physics, especially the discovery of the law of the photoelectric effect."
