Albert Einstein, the most popular scientist around the world, is 130 year old today. To memorize his great contribution to science, especially physics, proudly I write his biography today. Just to let you know, I cannot write anything about him, except this preface words. However, do not worry, I will compile some articles about him and rewrite it here. It is caused by the fact that I absolutely do not know anything about physics.

Albert Einstein was born at Ulm, in Württemberg, Germany, on March 14, 1879. Six weeks later the family moved to Munich, where he later on began his schooling at the Luitpold Gymnasium. Later, they moved to Italy, Albert continued his education at Aarau, Switzerland, and in 1896 he entered the Swiss Federal Polytechnic School in Zurich to be trained as a teacher in physics and mathematics. In 1901, the year he gained his diploma, he acquired Swiss citizenship and, as he was unable to find a teaching post, he accepted a position as technical assistant in the Swiss Patent Office.

In 1905, while he was working in the patent office, Einstein had four papers published in the Annalen der Physik, the leading German physics journal. These are the papers that history has come to call the Annus Mirabilis Papers:
1. His paper on the particulate nature of light put forward the idea that certain experimental results. Notably the photoelectric effect could be simply understood from the postulate that light interacts with matter as discrete “packets” (quanta) of energy. An idea that had been introduced by Max Planck in 1900 as a purely mathematical manipulation, and which seemed to contradict contemporary wave theories of light (Einstein 1905a).
2. His paper on Brownian motion explained the random movement of very small objects as direct evidence of molecular action, thus supporting the atomic theory. (Einstein 1905c)
3. His paper on the electrodynamics of moving bodies introduced the radical theory of special relativity, which showed that the observed independence of the speed of light on the observer’s state of motion required fundamental changes to the notion of simultaneity. Consequences of this include the time-space frame of a moving body slowing down and contracting (in the direction of motion) relative to the frame of the observer. This paper also argued that the idea of a luminiferous aether—one of the leading theoretical entities in physics at the time—was superfluous. (Einstein 1905d)
4. In his paper on mass–energy equivalence (previously considered to be distinct concepts), Einstein deduced from his equations of special relativity what has been called the twentieth century’s most well known equation: E = mc2. This suggests that tiny amounts of mass could be converted into huge amounts of energy and presaged the development of nuclear power. (Einstein 1905e)

In 1922, he awarded the 1921 Nobel Prize in Physics, “for his services to Theoretical Physics, and especially for his discovery of the law of the photoelectric effect”. This refers to his 1905 paper on the photoelectric effect: “On a Heuristic Viewpoint Concerning the Production and Transformation of Light”, which well supported by the experimental evidence by that time. The presentation speech began by mentioning “his theory of relativity [which had] been the subject of lively debate in philosophical circles [and] also has astrophysical implications which are being rigorously examined at the present time.” (Einstein 1923)

At all, Einstein’s researches are, of course, his more important works include Special Theory of Relativity (1905), Relativity (English translations, 1920 and 1950), General Theory of Relativity (1916), Investigations on Theory of Brownian Movement (1926), and The Evolution of Physics (1938). His non-scientific works, About Zionism (1930), Why War? (1933), My Philosophy (1934), and Out of My Later Years (1950) are perhaps the most important.

Finally, he died on April 18, 1955 at Princeton, New Jersey. Nevertheless, his name and contribution are always regarded until now.
