Albert Einstein (1879-1955) was a German theoretical physicist and one of the leading figures in the revolution of physics in the 20th century. His research and discoveries contributed greatly to establishing the foundations of modern physics.

  In a paper published in 1905, Einstein introduced the special theory of relativity. It suggested that time and space are not absolute concepts but relative. In particular, the equivalence of mass and energy was explained by the famous equation

  In 1915, Einstein completed his general theory of relativity. The theory explains that gravity is caused by the curvature of space and time. This was an important discovery to replace Newton's theory of gravity, and became the basis of modern cosmology.

  In 1905, Einstein published a paper explaining the photoelectric effect. The study explained that light consists of photons, which are particles, and that electrons are emitted when the particles of light collide with a metal surface. For this achievement, he was awarded the Nobel Prize in Physics in 1921.

 In 1905, Einstein also published a paper on Brownian motion. In this paper, he explained the phenomenon in which particles move randomly in a liquid, which became important evidence to experimentally prove the existence of molecules and atoms.

   Einstein was born in Ulm, Germany in 1879. He was educated in many European countries, and received a degree in Switzerland. In 1933, due to the rise of the Nazi regime, he moved to the United States and continued his research at Princeton University. He died in Princeton, New Jersey, the United States in 1955.

Not only did Einstein's work have a profound influence on physics, but his ideas and philosophy also had a great influence on the development of science and the public's understanding of science.
