Ulm, Germany

Died: 18 April 1955.

Princeton, Massachusetts

German-born American physicist and scientist

German-born American physicist (one who studies matter and energy and their relations), Albert Einstein revolutionized physics. Best known for his theory of relativity, which considers that measurements of time and vary depending on the circumstances, such as transaction status as observers.

Early years and education

Albert Einstein was born on March 14, 1879 in Ulm, Germany, but grew up and was educated in Munich, Germany. Students were poor, and some of his teachers thought he might be retarded (mentally) and couldn't speak fluently (with ease and grace) at the age of nine. Still, he was intrigued by the laws of nature, suffering from a deep sense of wonder when perplexed leash clearer, not real, the compass needle. He began playing the oud at the age of six years, and will continue to play throughout his life. At age twelve he found Engineering (points, lines and surfaces) and clear and I took some proofs. And Einstein had mastered calculus (Supreme mathematics model is used to solve problems in physics and engineering) before the age of 16.

Official secondary education over Einstein at the age of sixteen. He hated school, and just as he was planning to find a way to leave without hurting his chance to enter University, his teacher called him because of his bad influence on his teammates. Einstein tried to enter "wasn't the Federal Institute of technology (fit) in Zurich, Switzerland, but his knowledge of subjects other than math up to par, he failed the entrance exam. On the advice of the master, the first time he got a degree in Switzerland, Aarau, Canton school and in 1896 he was admitted automatically to fit. There he came to realize he was interested more and more suitable for Physics for math.

Einstein studied passed out comfort in 1900, but because of the opposition of one of his professors, and was unable to go for university teachers asistanchib. In 1902 he was hired as an inspector at the Patent Office in Bern, Switzerland. Six months later he married mark Mileva, a former colleague in Zurich. And had two sons. He was in Bern, too, that Einstein, at twenty-six, complete the doctoral requirements, and wrote the first scientific papers.

Famous papers

Thermodynamics (thermal processes) with deep impression on Einstein. From 1902 until 1904 he rework the foundations of thermodynamics and statistical mechanics (strong and affect a study on this issue); direct revolutionary action background papers in 1905, one on Brownian motion.

In 1827, first noticed in Brownian Scottish plant (botanical studies world) Robert Brown (1773-1858), small particles suspended in a liquid such as water, rapid and irregular movement. Einstein, unaware of the previous remarks, Brown concluded from his study that a proposal like this should exist. Guided by the thought that if the liquid molecules are composed of atoms, molecules and put them into practice. And found that the particles are moving forward in time. Einstein proved that moving forward is directly linked to the number of atoms per gram atomic weight. This day is one braonih the most direct evidence of the existence of atoms.

(Light) behaves as if it consists of particles and waves energy. And provided the equivalent of the photoelectric effect, which is the electron particles with more mass, which she is said to have "positive electric charge and expelled (particles in the outer part of the corn which is said to have" negative "electrical charge equal to protons) from the metal surface exposed to light. Einstein proved that draws electrons in a steady stream, but like bullets from a gun, and in units, or "quanta". Although Einstein's famous equation for the photoelectric effect-who won the Nobel Prize in physics 1921 — seems obvious today, and was very bold prediction in 1905. Not even after years, Milliken a.r. Finally actually managed to assure everyone of all to satisfaction.

Einstein's relativity research came to the general law of nature, which would explain the problem that occurred to him when he was 16: If one works in, say, 4 4 mph (6.4 km/h) along with a train that moves in 4
