The kinetic energy of the emitted electrons depends on the… In Einstein reached perhaps the lowest point in his life. Desperate and unemployed, Einstein took lowly jobs tutoring children, but he was fired from even these jobs.
Princeton, Massachusetts German-born American physicist and scientist The German-born American physicist one who studies matter and energy and the relationships between them Albert Einstein revolutionized the science of physics.
He is best known for his theory of relativity, which holds that measurements of space and time vary according to conditions such as the state of motion of Albert einstein a condensed biography observer. Early years and education Albert Einstein was born on March 14,in Ulm, Germany, but he grew up and obtained his early education in Munich, Germany.
He was a poor student, and some of his teachers thought he might be retarded mentally handicapped ; he was unable to speak fluently with ease and grace at age nine. Still, he was fascinated by the laws of nature, experiencing a deep feeling of wonder when puzzling over the invisible, yet real, force directing the needle of a compass.
He began playing the violin at age six and would continue to play throughout his life. At age twelve he discovered geometry the study of points, lines, and surfaces and was taken by its clear and certain proofs.
Einstein mastered calculus a form of higher mathematics used to solve problems in physics and engineering by age sixteen. He disliked school, and just as he was planning to find a way to leave without hurting his chances for entering the university, his teacher expelled him because his bad attitude was affecting his classmates.
Einstein tried to enter the Federal Institute of Technology FIT in Zurich, Switzerland, but his knowledge of subjects other than mathematics was not up to par, and he failed the entrance examination. On the advice of the principal, he first obtained his diploma at the Cantonal School in Aarau, Switzerland, and in he was automatically admitted into the FIT.
There he came to realize that he was more interested in and better suited for physics than mathematics. Einstein passed his examination to graduate from the FIT inbut due to the opposition of one of his professors he was unable to go on to obtain the usual university assistantship.
In he was hired as an inspector in the patent office in Bern, Switzerland. Six months later he married Mileva Maric, a former classmate in Zurich.
They had two sons. It was in Bern, too, that Einstein, at twenty-six, completed the requirements for his doctoral degree and wrote the first of his revolutionary scientific papers. Famous papers Thermodynamics the study of heat processes made the deepest impression on Einstein. From until he reworked the foundations of thermodynamics and statistical mechanics the study of forces and their effect on matter ; this work formed the immediate background to his revolutionary papers ofone of which was on Brownian motion.
In Brownian motion, first observed in by the Scottish botanist scientist who studies plants Robert Brown —small particles suspended in a liquid such as water undergo a rapid, irregular motion. He was guided by the thought that if the liquid in which the particles are suspended is made up of atoms, they should collide with the particles and set them into motion.
He found that the motion of the particles will in time experience a forward movement. Einstein proved that this forward movement is directly related to the number of atoms per gram of atomic weight.
Brownian motion is to this day considered one of the most direct proofs of the existence of atoms. He presented an equation for the photoelectric effect, in which electrons particles in the outer portion of an atom that are said to have a "negative" electrical charge equal to that of protons, particles with a larger mass that are said to have a "positive" electrical charge are ejected from a metal surface that has been exposed to light.
Einstein proved that the electrons are not ejected in a constant stream but like bullets from a gun, in units, or "quanta. Not until years later did R. Einstein realized that no matter what speed the observer is moving at, he must always observe the same velocity of light, which is roughlymiles per secondkilometers per second.
He also saw that this was in agreement with a second assumption: Academic career These papers made Einstein famous, and universities soon began competing for his services. Inafter serving as a lecturer at the University of Bern, Einstein was called as an associate professor to the University of Zurich.
Two years later he was appointed a full professor at the German University in Prague, Czechoslovakia. Within another year-and-a-half Einstein became a full professor at the FIT. Finally, in the well-known scientists Max Planck — and Walther Nernst — traveled to Zurich to persuade Einstein to accept a lucrative profitable research professorship at the University of Berlin in Germany, as well as full membership in the Prussian Academy of Science.
He accepted their offer insaying, "The Germans are gambling on me as they would on a prize hen. I do not really know myself whether I shall ever really lay another egg. In Einstein was appointed to a lifelong honorary visiting professorship at the University of Leiden in Holland.Albert Einstein was born in Ulm, in the Kingdom of Württemberg in the German Empire, on 14 March His parents were Hermann Fields: Physics, philosophy.
Physics (from the Ancient Greek φύσις physis meaning "nature") is the fundamental branch of metin2sell.com primary objects of study are matter and energy. Physics is, in one sense, the oldest and most basic academic pursuit; its discoveries find applications throughout the natural sciences, since matter and energy are the basic constituents of the natural world.
Brief Overview. Albert Einstein was born in in Germany, the first child of a bourgeois Jewish couple. The young Albert displayed an early interest in science, but he was unhappy with the principles of obedience and conformity that governed his Catholic elementary school.
Albert Einstein was born in Ulm, Kingdom of Württemberg, to a German Jewish family. He was the son of Pauline (Koch) and Hermann Einstein, a featherbed salesman. Albert began reading and studying science at a young age, and he graduated from a Swiss high school when he was Albert Einstein was a famous physicist.
His research spanned from quantum mechanics to theories about gravity and motion. After publishing some groundbreaking papers, Einstein toured the world and gave speeches about his discoveries. Albert Einstein was born on March 14, in Ulm, the first child of the Jewish couple Hermann and Pauline Einstein, née Koch.
In June the family moved to Munich where Hermann Einstein and his brother Jakob founded the electrical engineering company Einstein & Cie. Albert Einstein's sister Maria, called Maja, was born on .
