Albert Einstein’s name is synonymous with genius, and his wild hair is a trope of its own for mad scientists and popular culture professors.
Einstein’s discoveries led to modern inventions such as paper towels, solar energy, stock market forecasting and laser pointers, but his theory of general relativity is often considered his most significant contribution.
Here’s a look at the life and work of Einstein, who is considered one of the most influential physicists of the 20th century.
What did Albert Einstein invent?
Einstein published four notable articles during his year of miracles in 1905 while working at a Swiss patent office:
In his first paper, Einstein applied German physicist Max Planck’s quantum theory to light to explain the photoelectric effect. He went on to win the Nobel Prize for this work in 1921.
His second paper used Brownian motion, or the motion of tiny particles suspended in a liquid, to share the first experimental evidence that atoms exist, according to Britannica.
His third paper, On the Electrodynamics of Moving Bodies, offered Einstein’s special theory of relativity. His fourth paper led to the development of the most recognized equation in science:AND=mc2.
E=mc2 basically says that mass and energy are the same physical entity. This equation, and his other theories, helped develop the atomic bomb, although Einstein was never asked to participate in the American-led atomic weapons effort called the Manhattan Project.
In 1915 he published his general theory of relativity, the first theory of gravity since the publication of Sir Isaac Newton’s “Principia” in 1687. Newton’s work established gravity both as a concept and as a universal law, stating that gravity is a constant force pulling objects. The tug will be stronger if the object has more mass and weaker if you increase the distance between two objects.
Einstein’s theory, which he discovered while he was director of the Kaiser Wilhelm Institute for Physics at the University of Berlin, addressed the explanation of gravity. His theory of general relativity states that gravity is a natural consequence of a mass existence in space that mass can bend space and time. Newton didn’t believe that objects affected space, writes the American Museum of Natural History, but Einstein did, and he even singled out a fourth dimension known as spacetime in his 1905 special theory of relativity.
Einstein also predicted the existence of gravitational waves in his theory of relativity. Instead of seeing gravity as a constant, immediate force, Einstein proposed that a large change in mass would cause space to contract and stretch by a small amount.
Einstein’s last work, which was unfinished when he died, was on unified field theory, which uses a single theoretical framework to describe fundamental forces and the relationships between elementary particles, according to Britannica.

When did Albert Einstein die?
Einstein died at the age of 76 on April 18, 1955, of an abdominal aortic aneurysm. According to AMNH, Einstein denied surgery for the burst blood vessel, saying I want to go when I want to go. He has no taste in prolonging life artificially. I have done my part; it’s time to go. I will do it elegantly.
What was Albert Einstein’s IQ?
There are no definitive answers or proof that Einstein tested his IQ, but his IQ is estimated to be around 160. Theoretical physicist Stephen Hawkings’ IQ is estimated to be the same, but the two physicists are far from the highest IQ. high recorded despite popular acclaim.
The average IQ score in the United States is 98.
