Einstein s upbringing, what education he received, what major discoveries he made

When Einstein graduated from university, he was in the midst of an economic crisis, and because he was of Jewish descent, had no connections, and had no money, he had to be unemployed at home. In order to make a living, he had to put up advertisements everywhere and earn 3 francs an hour by lecturing physics. This period of unemployment helped Ezistan a lot.

In the course of his lectures, he reflected on traditional physics, which contributed to his violent impact on traditional academic views. After five weeks of intense and excited struggle, Einstein wrote the 9,000-word ** "On the Electrodynamics of Moving Bodies", from which the special theory of relativity was born.

1. Smoke detector.

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. 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., 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.

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 flying electrons will create a blurry image on the display, making it impossible for you to work, and of course, you won't be able to play a great computer game.

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.

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.

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 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.

Einstein's growth refers to the development and growth of Einstein from childhood to adulthood, and there may be several possibilities for the role played by the last paragraph. Since you haven't provided specific text or context, I'll provide two common scenarios to explain what the last paragraph does.

Summarization: In the text, the last paragraph may serve as a summary and induction. It can summarize the important characteristics of Einstein's growth, key moments, or achievements.

By summarizing the entire story or discourse, readers can better understand and review the process of Einstein's growth.

Echoing the theme or emphasizing the idea: Another possibility is that the last paragraph is used to echo or emphasize the theme or point of view in the text. It may ask a question that deepens understanding or makes the reader think about it to get them interested and thinking.

Such a paragraph can make a strong impression on the entire article and provide the reader with an extension for thought.

It should be noted that the specific role and effect should also be determined according to the content and structure of the text. So, if you can provide more information about the text, I can give it more specific and accurate.

When everything has been forgotten, all that remains is education. These are the remarks of the famous American psychologist Berges Frederick Skinner in the magazine "New Scientist".

This phrase was originally coined by Skinner, and later Albert Einstein said in one of his lectures: "A philosopher once said: When you forget everything you learn in school, all that remains is education." ”

The previous sentence "a philosopher said" can be found in Einstein's anthology, and Einstein himself clearly said that it was not his original. Since he did not name the original author, it was later assumed that the phrase was from Albert Einstein. Skinner, who was about the same time as Einstein, was a pedagogue and pedestrian, and his popularity and influence at that time were not inferior to Einstein's.
