Einstein s achievement, what is Einstein s achievement?

Albert Einstein was born in Ulm, Württemberg, Germany, and ushered in a new era of modern science and technology, and is widely regarded as the greatest physicist after Galileo.

1. The reason why Einstein won the Nobel Prize.

In 1905, Albert Einstein proposed the photon hypothesis, a breakthrough theory that could not only explain the photoelectric effect, but also promote the birth of quantum mechanics, for which he was awarded the Nobel Prize in Physics in 1921.

2. Einstein's achievements are as follows:

1. The theory of relativity.

The theory of relativity is a major revolution in the field of physics, which negates the absolute view of time and space of classical mechanics and profoundly reveals the essential properties of time and space.

2. The establishment of the general theory of relativity.

Einstein's general theory of relativity states that space and time bend due to the presence of matter, and that the gravitational field is actually a curved space-time.

The theory of relativity creatively links the time dimension with the three-dimensional space, and puts forward the concept of "four-dimensional space-time", which raises the entire human understanding of the world and the universe to a new level, and the theory of relativity is known as one of the two pillars of modern physics in the 20th century.

3. The law of conservation of energy.

The law of the immortality of matter speaks of the imperishability of the mass of matter; The law of conservation of energy talks about the conservation of energy in matter.

4. Photoelectric effect.

When light hits the metal, it causes a change in the electrical properties of the substance, and this phenomenon of photoelectric power is collectively known as the photoelectric effect.

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.

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.

Before administering radiation** to you, your doctor needs to estimate the damage that X-rays may cause to your cells, based on Einstein's e=mC2.
