# Everything you did not know about Albert Einstein

**Although he is best known for the theory of relativity, especially after the mass and energy equivalence (E = mc2), there are many things about Albert Einstein that are not known or misinterpreted.**

The Theoretical Physicist, one of the greatest minds and one of the most important figures in the history of the world, was born in Ulm, Germany, on March 14, 1879, and died on April 18, 1955, in Priston, New Jersey.

He set out the special and general theory of relativity by making a revolution in modern physics. In addition, he contributed to the progress of quantum theory and statistical mechanics.

The Nobel Prize was awarded in 1921 for the explanation of the photoelectric effect, as well as for the contribution to the development of theoretical physics.

**Was Einstein a bad student?**

Einstein had problems learning his language while he was small, and for that reason, his parents carried him to the doctor. He was also very rebellious and was thrown out of a school. But such things created a genius from him. The attitude he had with the authorities allowed him to question the previous knowledge. His slow verbal development focused his interests on space and time, which for many adults was not an interesting topic for thinking. At the age of five he received a compass from his father, and by the end of his life, he was interested in the magnetic fields. It is interesting that the world preferred to think in pictures rather than words.

**What was it about mathematics?**

One of the most common opinions about Einstein is that he was bad in mathematics. This is referred to as a generally accepted fact and is often used as a way to motivate students to move on. If you search on “Einstein bad in mathematics” on Google, you will receive more than 500,000 links.

Although Einstein’s life offers many ironies, this is not one of them. When in 1935 they showed him the text of the column “The Ripley’s Believe it or Not” about falling into the mathematics exam, Einstein laughed loudly. He replied that he never fell into mathematics and that before his 15 years he understood differential equations and integral calculations.

In the elementary school, he was among the best and above all expectations of average knowledge of mathematics. By the age of 12, according to his sister, he was very successful in solving problems in advanced arithmetic. In order to exercise during the summer, parents bought him a task assignment, and apart from having successfully solved the tasks, he also made the theories about his own way of solving.

Did he prefer to think in pictures or words?

His greatest successes have been made thanks to visual observations and images in his head, not experimenting in laboratories. These are the so-called thought experiments. At the age of 16, he tried to imagine riding on a light beam. The question was whether in such a case

when the spectator reached the speed of light, he would actually see motionless light rays.

The problem was that Maxwell’s equations forbade it. Einstein knew that mathematics was a language in which nature describes his miracles, so he could visualize the equations. He devoted the next ten years to similar thought experiments and reached the special theory of relativity.

What kind of thought experiment came to the general theory of relativity?

The general theory of relativity came to imagine a man in a lift that freely falls. In such a situation, the man would float freely, and would also float things that he would take out of his pockets. The same would happen if the man was in the same cabin of the elevator somewhere in space.

On the other hand, the man in a cabin that rises rapidly through the universe, the feeling would be to attract gravity. From the equality between accelerated motion and gravity, he carried out the general theory of relativity.

What kind of thought experiment can explain gravity?

The trumpet is a good example of the space description. If we put a heavier ball on it, we will notice that it will come to the middle and will make a hole that will distort the entire trampoline. If we put a few billiard balls out of the edge of the trampoline, we will notice that they will spirally move towards the ball in the center. In the same way, the general theory of relativity explains that the mass curves space and that the movement of bodies around another body is the result of the curvature of space.
