Albert Einstein 

Biography

Einstein was born in 1879 in the city of Ulm in Germany. He did his matriculation in Switzerland. In 1900, he became a citizen of this country. He received his doctorate from the University of Zurich in 1905. However, he could not immediately get any job at the university.

In the same year, he published papers on special relativity light-induced electronic effects, and Brownian motion theory. Over the next few years, these papers, especially the paper on relativity, made him one of the world's most brilliant and brilliant scientists. His ideas were highly controversial.

No other scientist except Darwin has had so much controversy over his ideas. Nevertheless, in 1913 he got a teaching job at the University of Berlin. Within a short period of time, he became the director of the "Kaiser Dalam Institute of Physics" and an activist for the "Prussian Academy of Mines". These positions gave him free time to research topics of his choice.

The German government later regretted making such a generous offer to Einstein it didn't happen because only in the next two years he was able to formulate the general theory of relativity. He received the Nobel Prize in 1921.

During the remaining half of his life, Einstein achieved worldwide fame. He is considered to be the most popular scientist in the world. Einstein was Jewish, and his institution came under fire in Germany as Hitler came to power. In 1933 he moved to Princeton, New Jersey, and started working at the Institute of Advanced Science.

In 1940 he got immortal citizenship. His first marriage ended in divorce. The second marriage, however, was happy. He died in 1955 in Princeton.

Albert Einstein, the great scientist of the 20th century and the supreme godfather in history, who is a man with everything, is famous for his theory of relativity. Actually, it is a theory consisting of two theories.

 

Theory of Relativity

The special theory of relativity was formulated in 1905 and the general theory of relativity came to light in 1915. Which can be called Einstein's theory of gravitation in better words. Both theories are very complex. An attempt to describe them in detail here will be avoided, but some important points are as follows. A well-known saying is that "everything is extra".

However, Einstein's theory is not a rehash of this philosophically outdated idea, but rather a clear mathematical statement of the process by which scientific measurements add up. It is clear that the subjective evidence of time and place depends on the state of the observer.

Before Einstein, most people believed that behind these subjective impressions were real dimensions (Distances) and Absolute Time exists which can be measured objectively with the most accurate instruments.

Einstein's theory created a revolution in scientific thought in the form of estrangement from the existence of absolute time. The following example will highlight the extent to which his theory has changed our ideas about space and time.

Imagine a spacecraft, for example, "a spacecraft that rises above the Earth at a speed of 100,000 kilometers per second. This velocity has been measured by the spacecraft and observers on Earth and they agree.

Meanwhile, Another "spaceship" flies towards the first one, but its speed is much faster. If observers on Earth measure the speed of "they will know that it is 180,000 km from Earth moving away at a speed of km/s. Spacecraft observers would reach the same conclusion.

Both spacecraft are flying in the same direction. This would suggest that the difference in their velocities is 80,000 kilometers per second and that the high-speed spacecraft is ahead of the spacecraft at this rate.

Einstein's theory predicts that when measurements are made from both ships, observers from both ships will agree that the distance between them is increasing at a rate of 100,000 kilometers per second, not 80,000 kilometers is the speed per second.

In view of this situation, such a conclusion would seem favorable. The reader will be concerned that some literal charisma is being demonstrated here. Or that certain style details have been deleted altogether.

This result has nothing to do with the subtleties of spacecraft or the forces driving them. It is neither due to the error of observation nor to any defect in the measuring instruments themselves. No trickery was shown. According to Einstein this result (which of velocities can be derived immediately under his term of synthesis) is derived from the fundamental nature of space and time.

The whole matter seems highly theoretical, and no doubt a number of people will dismiss the theory of relativity as a kind of wishful thinking of no practical utility. Undoubtedly, no one has made such a mistake since 1945 when the atomic bombs were dropped on Hiroshige and Nagasaki.

Conclusions of Einstein's Theory of Relativity

One of the conclusions of Einstein's theory of relativity is that matter and energy are identical in a certain respect, the relationship between them is described by the symbol "E-M".

In this, ta represents energy, " represents equal distance, and "C" represents the speed of light while "C2" which is equal to 186,000 miles per second, is a large quantity while C means multiplying C becomes a very large quantity indeed. From this, it can be concluded that even a small change in the amount of matter causes the release of an enormous amount of energy.

First Atomic Bomb

One cannot develop an atomic bomb by simply using the "E-M2" key. It should be noted that many people contributed to the development of atomic energy.

In 1939, he wrote a letter to US President Roosevelt in which he gave the plan to develop nuclear weapons and suggested that before the Germans do so, America should take the lead. As a result of the E-proposal, the "Maintain Project" came into being, and progress was made toward the development of the first atomic bomb.

Theory of Humanity

A general theory of humanity is a starting point for Einstein suggests that the effects of gravity are not due to different physical forces, as is commonly assumed, but rather are the result of the curvature of space. It was an amazing concept.

Special relativity has stimulated heated debates. On one point, however, they agreed that it was a mind-boggling scientific theory that had no precedent in human history. That is why the number of misunderstandings related to it was not less.

 

Measurement of the Curvature of Space

What is meant by saying that space is curved? Einstein not only proposed such a theory, but he expressed it in a clear mathematical form. With the help of this inter-predictions can be made and the validity of the hypothesis can be tested. Further observations, the most spectacular of which were made during a solar eclipse, proved Einstein's mathematical equation correct.

The general theory of relativity is distinguished from all other scientific laws in several respects. First, Einstein did not formulate his theory on the basis of careful experiments but derived it from the power of proportions and mathematics. That is, on a rational basis, as was the practice of Greek philosophers and medieval scholars (in doing so, he rejected the basic empiricism of modern science).

Einstein's theory stood the test of time. The result of Einstein's approach is that the general theory of relativity is one of the most beautiful, brilliantly concrete, and powerful of all scientific theories. It is considered rationally satisfactory.

The general theory of relativity is also excellent in another respect. Most other scientific laws are more or less justified and, as far as we know, true in some, if not all, situations. Exceptions have no place in the general theory of relativity. There is no situation, either theoretically or empirically, in which the predictions of general relativity are even remotely valid.

Future trials will better assess the validity of this theory. But where the general theory of relativity is the closest such approximation to the truth beyond which science has not yet progressed. Although Einstein's fame is due to his theory of relativity, his other scientific theories also made him popular.

Einstein received the Nobel Prize in Physics for his descriptive paper on the electromagnetic effect produced by light. This is an important phenomenon that has greatly puzzled physicists. In this paper, he hypothesized the existence of the "photon" or the composite component of light.

It has long been established by experiments that light is based on electromagnetic radiation. And it was clear that these waves and compositional components were mutually exclusive.

Einstein's hypotheses severely overruled this classical theory. Not only did his law of light prove to be very successful in practice, but his "photon" hypothesis also had a profound impact on the quantum theory of electronics, a key component of that theory today.

 

Einstein's Comparison with Isaac Newton

In assessing Einstein's worth and value, his comparison with Isaac Newton is thought-provoking. Newton's theories are relatively misunderstood. On the other hand, Einstein's theory of relativity is very serious. Even if they are defined somewhat clearly. While some of Newton's ideas contradicted many of the prevailing ideas of his time, his ideas were nevertheless directly independent.

On the other hand, the theory of relativity is full of contradictions. It is due to Einstein's genius that in the beginning, when his ideas were in the form of crude hypotheses of a young man, he never dismissed his ideas because of these contradictions.

He continued his deliberations until he was able to prove that these contradictions apparently existed. And that in each instance there is a complicated but complicated way to resolve this violation.

There is also a correct procedure. Today we would accept Einstein's theories as far more correct than Newton's But why Einstein was counted after Newton in this list? Because it was Newton's theories that laid the foundations of modern science and technology. Much of modern technology today owes its development to Newton, not Einstein.

There is another reason that has assigned Einstein this rank on this list. In most instances, multiple people made significant improvements to a single key concept. As can be seen in examples from the history of communism or the theory of electricity and magnetism.

Although not all credit goes to Einstein for inventing the theory of relativity, his contribution is by far the greatest. It would be fair to say that, as we have assumed in the examples of other important theories, for this theory also we can attribute only one human being as the main responsible.

 

Personally, Einstein's Qualities

Einstein was always keenly interested in the world around him and used to comment on political issues. He was staunchly opposed to political authoritarianism, a pacifist who was an ardent follower of "man and animal".

He was an individualist in matters of dress and social customs. He had a high sense of humor and was an excellent violinist. Newton's epitaph better applies to Einstein. Mortals should celebrate that such an endlessly adoring species.
