Albert Einstein’s Great Inventions

Albert Einstein’s Great Inventions That Affected the World

A theoretical physicist and philosopher, Albert Einstein is one of the most influential scientists of the 20th century. So what did Albert Einstein invent? Einstein is known mainly for his theoretical work and did not invent anything; It is a lesser-known fact that the Einstein Refrigerator, just one of his inventions, was patented. Albert Einstein was born on March 14, 1879, in Ulm, Germany. Known as the father of modern physics, Einstein was awarded the Nobel Prize in 1921 for his contribution to Theoretical Physics. The Einstein refrigerator is an important invention of Albert Einstein. The theory of relativity proposed by Einstein is one of his important contributions to the study of the physical world. Many of his inventions may not be considered inventions in the traditional sense. The Einstein Refrigerator is Einstein’s only real invention. The history of his inventions shows that many of his inventions were theoretical concepts that formed the basis of further research on the subject.

Einstein Refrigerator

It is an absorption refrigerator that uses heat to power a cooling system or to refuel. Albert Einstein invented this refrigerator with the help of a former student, Leo Szilard. The Einstein Refrigerator was patented on November 11, 1930. Einstein and Szilard’s main goal in developing this refrigerator was to make improvements in home cooling technology. The news of an accident caused by the breaking of the refrigerator seal inspired Einstein and Szilard to find a safe alternative to the technology used in those days, and the feature of the Einstein Refrigerator, however, is that it does not contain moving parts.

Contribution to Nuclear Physics Theoretical Studies

It cannot be said that Einstein was directly involved in the invention of the atomic bomb. E = mc² equation formulated by Einstein played a central role in the development of this nuclear weapon. However, it should be noted that Einstein was not a member of the team that developed the atomic bomb. In fact, he wrote to US President Roosevelt that he had called on the invading Germans to set up an atomic bomb before attempting to do so. However, it condemned the use of atomic bombs by the United States that caused mass destruction and bloodshed in Hiroshima in Japan. According to the E = mc² equation, mass and energy can be changed to some extent. E = mc² this equation consists of the following variables and constants.

  • E refers to the energy
  • m refers to mass
  • c is constant, the speed of light.

Special Relativity Theory

This theory was developed by Albert Einstein in an effort to reconcile the laws of the electromagnetic field with the laws of classical mechanics. In 1905, Einstein presented the special theory of relativity in an article entitled Electrodynamics of Moving Bodies. The two basic concepts given constitute the essence of this theory and these concepts are as follows:

  • According to the first concept, uniform motion is always relative.
  • According to the second concept ‘rest state’ can not be defined – this means it is not absolute.

General Theory of Relativity

The research on the Theory of Relativity was among Albert Einstein’s great achievements. Einstein’s assumption was the first in the series of explanations on the General Theory of Relativity. In this context, an important assumption put forward by Einstein is expressed as follows: the gravitational fields are equal to the accelerations of the reference frame. This postulate can be detailed with the help of the example below. People in an elevator (descending) do not fully understand what force (the force of gravity or the acceleration of the elevator) drives their movements.

Einstein added to Newton’s theory of gravitational pull by stating that the apple did not just fall to the ground due to gravity, but attracted asteroids and other space objects due to the dent in the fabric of the earth’s orbit. Thus, it empowers us to the advantage as a parking lot for orbiting satellites that can be used for their technological advantages. It has also been used to take men to and from the moon.

Photoelectric Effect

In one of his articles on the photoelectric effect, Einstein stated that light consists of particles. He also stated in this article that these light particles (photons) contain energy. The energy contained in photons is directly proportional to the radiation frequency. It was previously assumed by scientists that light travels in the form of waves. The studies and discoveries made by Einstein helped to understand some of the basic concepts of physics. In fact, the quantum concept has revolutionized physics research. In 1921, Albert Einstein was awarded the Nobel Prize for his research on the photoelectric effect. The relationship between energy and radiation frequency is given below with the help of the formula.

E = h in this formula,

E means energy

The h symbol is Planck’s constant

Einstein’s Explanation of the Brownian Movement

In 1827, Robert Brown, a botanist from England, observed a random, agitated movement of pollen grains suspended in water. At that time, he could not explain the reason behind this kind of movement. In 1905, Albert Einstein made an explanation about such a random motion of suspended particles. According to Einstein, thermal molecular movements are responsible for the random movements of microscopically visible objects suspended in a liquid.

Bose-Einstein Condensate (BEC)

Bose-Einstein condensate was predicted by Albert Einstein in 1924. Bose-Einstein Condensate (BEC) is an entity formed as a result of the combination of individual atoms when cooled to -459.67 ° F. – 273.15 ° C. Einstein predicted the BEC on the basis of quantum formulations provided by an Indian scientist, Satyendra Nath Bose. However, in 1995 the BEC was made for the first time. Eric Cornell and Carl Wieman played an important role in the production of BEC.

Einstein’s Statement That The Sky Is Blue

The phenomenon of the scattering of light from the sun is the reason why it appears blue behind the sky. The electromagnetic field of light is responsible for inducing electric dipole moments in molecules that come into contact with light. Albert Einstein gave a detailed explanation about the phenomenon of scattering of light caused by molecules in the atmosphere. Albert Einstein was one of the greatest scientists of his time. However, he was not enthusiastic about learning and education as a whole during his school days. He did not like the strict teaching techniques and methods used in those days, and these teaching methods in no way helped to increase his interest in the learning process. Einstein’s academic performance was considered average by his teachers.

However, Einstein’s curious nature and his ability to understand complex mathematical concepts without assistance are signs of his extraordinary ability. He was able to learn Euclidean geometry at the age of 12 through self-study. In his childhood days, Einstein sat in a crowded room, happily solving math problems. Albert Einstein’s first job was a Patent Attendant at the Swiss Patent Office (Bern). Albert Einstein’s inventions and theories have greatly helped scientists of the 20th century. His theory of relativity can be considered as one of the important milestones in the history of scientific development.

Albert Einstein is known for his brilliant contributions to the field of physics and is particularly famous for his theory of relativity. Albert Einstein’s achievements are many and varied. These range from discoveries of the mysteries of the universe to being a supporter of peace and freedom of expression in a time of fear of communism. Albert Einstein is often called the father of the atomic bomb and is blamed for his invention, but historically this is not true and this fact must be straight. The only push in this direction was a letter to President Franklin D. Roosevelt urging the US to build the atomic bomb before the Germans did it. He just did this because he thought they were at a point where they could achieve it. He later said that if he had known that they would not succeed, he would not say anything to the President.

Anyway, everyone knows about the destruction and destruction caused by the atomic bomb in Hiroshima and Nagasaki during the Second World War. Apart from this great but dangerous invention, Albert Einstein had many achievements. His great achievements have given today’s scientists enough information about his universe to help take people into space, learn more about the sun near-Earth and stars millions of miles away.

These are just Albert Einstein’s great achievements. II. During World War II, Japan was told (which she immediately regretted) had an effect on the idea of ​​dropping the atomic bomb. It was also instrumental in promoting the state of Israel and actively supported freedom of thought and freedom in a period of hatred and racism. This great man was actively involved in scientific research, opening many doors for future researchers and scientists to explain the phenomena of space, light, and time.
