Albert Einstein.

Albert Einstein.

1. Albert Einstein was born on March 14, 1879 in Ulm (Germany) and died on April 18, 1955 in Princeton (USA).

   • Considered the most famous scientist of the 20th century, the German physicist is known for developing the Theory of Relativity and what is surely the most popular equation in history: E=mc2, the equivalence between mass and energy.

2. The theory of relativity includes both the theory of special relativity and the theory of general relativity, formulated mainly by Albert Einstein at the beginning of the 20th century, which sought to resolve the incompatibility between Newtonian mechanics and electromagnetism.

   • Basically, relativity asserted that the laws of physics could not depend on the speed at which you moved; all you could measure was the speed of one object relative to another.

3. The explanation of the photoelectric effect was the main work cited when Albert Einstein was awarded the Nobel Prize in Physics in 1921. Einstein's explanation, proposed in 1905, played an important role in the development of atomic physics.

   • He based his theory on a very bold hypothesis, since few of the experimental details were known in 1905. Moreover, the key point of Einstein's explanation contradicted the classical ideas of the time. Translated with www.DeepL.com/Translator (free version)
