Albert Einstein was a German-born theoretical physicist and a mathematician by profession, and one of the greatest masterminds of recent times, who enlightened us on the various subjects. He is best known for his theory of general relativity and his mass-energy equivalence formula, E = mc^2.

Accomplishments of Albert Einstein

How many things did Thomas Edison invent?

In his 76 years lifespan, he bagged 1093 patents (singly or jointly) and turned out to be the main force in the back of innovations like the phonograph, the bright light bulb and one of the earliest motion photo cameras. He additionally created the world’s first industrial research laboratory.

Here are few of Albert Einstein’s inventions, contributions, and key findings-

The first discovery of Albert Einstein?- The Brownian movement.

Einstein first became well-known in the year 1905 for showing the Brownian movement. Though the Brownian motion was first observed by the Scottish botanist Robert Brown in the year 1827 while observing pollen grains in water. The complete effect was finally described by Einstein. He proved the existence of particle and the movement of the particles due to random collision among them. He showed how the energy of the particles fluctuates and collides with climate variations. He helped to prove the existence of atoms and molecules which became the basis of all branches of Science.

Quantum Theory of Light

 Einstein’s quantum theory of light stated that light exists as tiny packets or particles of energy called photons that have wave-like properties. In this theory he also explained the emission of electrons from some metals they’re struck by lightning – this was called the photoelectric effect.

E=mc2

 His biggest achievement was the formula he invented and the correction he made by demonstrated the link between mass and energy. Before his discovery, mass and energy were viewed as distinct entities. He expressed the fact that mass and energy are the same physical entity and can be changed into each other. In the equation, the increased relativistic mass (m) of body times the speed of light squared (c2) is equal to the kinetic energy (E) of that body.

Nuclear discoveries are based on this formula.

Special Theory of Relativity

 Einstein’s special theory of relativity was given by him in 1905. It helped to explain how space and time are related to objects that are moving at a consistent speed in a straight line. Simply put, it states that when an object approaches the speed of light, its mass becomes infinite and it is unable to go any faster than the speed of light. This theory was an expansion of a relative theory first discussed by Galileo.

General Theory of Relativity

 Einstein published his general theory of relativity in 1915 and it became one of the most important theories developed for modern astrophysics. The general theory expanded on his previous special theory. This theory finds that gravity and motion affect time and space. Einstein used his equivalency theory to help form the basis of his relativity theory. The equivalency theory states that gravity’s pull on an object in one direction is equivalent to the rate of acceleration in the opposite direction. This helped him discover the theory of relativity by explaining how if the light is bent by acceleration than it must also be bent by gravity. In 1919, two separate space expeditions proved that Einstein was correct. These expeditions noted how starlight bent due to the force of gravity created by the sun during a solar eclipse. This theory also held to prove that there was an anti-gravity force at work in the universe that prevented everything from collapsing in on itself. Einstein called this the cosmological constant.

Einstein was interested in energy, light, space and time and possible connections between them. He saw light as being both particles and waves. His formula E = mc2 attempts to prove that matter and energy are different manifestations of the same substance.

Albert Einstein’s facts prove that acceleration and gravity are equivalent. His areas of investigation focused on connections between space, time and energy; wormholes; black holes; the possibility of time travel and the creation of the universe.

Einstein Was Blamed for the Atomic Bomb

One of our more unfortunate Albert Einstein facts is that his work in physics, especially his energy calculation that E = mc2, led to the later invention of the atomic bomb.

Einstein was certainly not involved in this research and regretted that his investigations into the link between energy, mass, and speed had such powerful consequences.

Einstein’s Brain Was Kept for 20 Years After His Death

In his last years of life, Albert Einstein knew he was ill and refused operations that would save his life. He died on April 18, 1955, of a ruptured abdominal aortic aneurism. Within seven and a half-hour of his death, his brain was stolen by a pathologist named Thomas Harvey. He kept his brain for 20 years and did a lot of researches. He wanted to know what made Einstein a genius.

In his lab, he sectioned the preserved brain into 170 parts, a process that took three full months to finish.

Those 170 sections were then sliced in microscopic slivers and mounted onto slides and stained. Harvey created 12 sets of slides with each set consisting of hundreds of slides.

Harvey retained two complete sets for his study while he gave the remaining ones to the leading pathologists of the world.
