Seventy years ago today, on April 18, 1955 (March 26, 1955 lunar calendar), Einstein died. Albert Einstein, the founder of the theory of relativity, on April 18, 1955, the famous physicist Einstein died in Princeton, New Jersey, USA. He received his doctorate in physics in 1905 and published his special theory of relativity in the same year. He published his general theory of relativity in 1915. In 1933, he was persecuted by German anti-Semitism and left his country. Einstein believed firmly that "the brotherhood inherent in human beings and the characteristics of each individual. But if someone asked me to prove it, I could not. Likewise, the human mind produces a higher understanding, but it cannot prove its production process. All great discoveries involve such a leap." Einstein was born in Ulm, Germany on March 14, 1879. A famous American theoretical physicist. Educated in Munich as a child, he graduated from the Zurich Institute of Technology in Switzerland in 1900. Naturalized in Switzerland. In 1905, he published a thesis on "New Determination of the Molecular Scale" in the journal of physics and obtained a doctorate in philosophy from the University of Zurich. He published 4 important papers "Study of the Motion of Suspended Particles in Still Liquids According to the Theory of Molecular Kinematics", "Discussion on the Generation and Transformation of Light", "On the Electrodynamics of Moving Bodies" and "The Relationship between the Inertia of Objects and Energy", which revolutionized the human view of the universe. In 1914, he served at the Prussian Academy of Sciences in Berlin. In 1916 he published Fundamentals of General Relativity. His theory of relativity was confirmed by photographs and subsequent calculations of a solar eclipse taken by a Royal Society scientific expedition on the island of Principe in the Gulf of Guinea on May 29, 1919, earning him great international fame. For his contributions to the laws of optoelectronics and theoretical physics, he was awarded the 1921 Nobel Prize in Physics. Einstein was recognized during his lifetime as one of the most creative figures in human history. During the first 15 years of the 20th century, he proposed a series of scientific theories; first asserted the equivalence of matter and energy; gave complete new concepts to space, time and attractive forces. His theory of relativity was more advanced than Newtonian physics and revolutionized science and philosophy. His mass-energy equation E = mC squared shows that particles of matter can be converted into huge energy, which has been confirmed by the power of atomic and hydrogen bombs. Einstein's life is unrivaled in human contribution to the understanding of the universe, and has been recognized as a scientific giant in the entire history of mankind. Died on April 18, 1955.
