The fourth paper was a mathematical addition to the special theory of relativity. This paper introduced an entirely new concept. Laws are the same everywhere in the universe. Television and other inventions are practical applications of Einstein's discoveries.Ī third paper, which had its beginnings in an essay he wrote at age 16, contained the “special theory of relativity.” Einstein showed that time and motion are relative to the observer, if the speed of light is constant and natural It also explained the photoelectric effect, the emission of electrons from some solids when they are struck by light. In it he proposed that light is composed of separate packets of energy, called quanta or photons, that have some of the properties of particles and some of the properties of waves. Einstein suggested that the movement was caused by the random motion of molecules of the suspension medium as they bounced against the suspended particles.Ī second paper laid the foundation for the photon, or quantum, theory of light. The first one provided a theory explaining Brownian movement, the zigzag motion of microscopic particles in suspension. Publication of the next four papers forever changed mankind's view of the universe. He received a doctorate for the first paper. In 1905, at age 26, he published five major research papers in an important German physics journal. In 1902 Einstein became an examiner in the Swiss patent office at Bern. He married his widowed cousin Elsa in 1919. They had two sons but were later divorced. He finished high school and technical college in Switzerland. He attended a rigorous Munich elementary school where he showed an interest in science and mathematics but did poorly in other areas of study. His theories of relativity led to entirely new ways of thinking about time, space, matter, energy, and gravity.Įinstein's work led to such scientific advances as the control of atomic energy and to some of the investigations of space currently being made by astrophysicists.Įinstein was born in Ulm, Germany, on March 14, 1879, of Jewish parents. Text C “Albert Einstein”Īny list of the greatest thinkers in history will contain the name of the brilliant physicist Albert Einstein. Write a short summary of the text C using the topical sentences. Divide text C into logical parts and find the topical sentences of each part. Look through the texts once more and say what is common in the theories of Albert Einstein and Niels Bohr.Ĥ. Speak about the role Albert Einstein and Niels Bohr played in building nuclear bomb.ģ. Get acquainted with the technical terminology in the field of physics: nuclear, quantum, structure, gravity, space, energy.Ģ.
In 1943 he fled German-occupied Denmark for the United States, where he advised on the development of the atomic bomb.
This resulted in the "Rutherford-Bohr atom." Back in Copenhagen in 1916, Bohr discovered the principle used to build nuclear weapons. Applying quantum theory to Rutherford's ideas about the structure of the atom.
