Albert Einstein born
On March 14, 1879, Albert Einstein is born, the son of a Jewish electrical engineer in Ulm, Germany. Einstein’s theories of special and general relativity drastically altered man’s view of the universe, and his work in particle and energy theory helped make possible quantum mechanics and, ultimately, the atomic bomb.
After a childhood in Germany and Italy, Einstein studied physics and mathematics at the Federal Polytechnic Academy in Zurich, Switzerland. He became a Swiss citizen and in 1905 was awarded a Ph.D. from the University of Zurich while working at the Swiss patent office in Bern. That year, which historians of Einstein’s career call the annus mirabilis—the “miracle year”—he published five theoretical papers that were to have a profound effect on the development of modern physics.
In the first of these, titled “On a Heuristic Viewpoint Concerning the Production and Transformation of Light,” Einstein theorized that light is made up of individual quanta (photons) that demonstrate particle-like properties while collectively behaving like a wave. The hypothesis, an important step in the development of quantum theory, was arrived at through Einstein’s examination of the photoelectric effect, a phenomenon in which some solids emit electrically charged particles when struck by light. This work would later earn him the 1921 Nobel Prize in Physics.
In the second paper, he devised a new method of counting and determining the size of the atoms and molecules in a given space, and in the third he offered a mathematical explanation for the constant erratic movement of particles suspended in a fluid, known as Brownian motion. These two papers provided indisputable evidence of the existence of atoms, which at the time was still disputed by a few scientists.
Einstein’s fourth groundbreaking scientific work of 1905 addressed what he termed his special theory of relativity. In special relativity, time and space are not absolute, but relative to the motion of the observer. Thus, two observers traveling at great speeds in regard to each other would not necessarily observe simultaneous events in time at the same moment, nor necessarily agree in their measurements of space. In Einstein’s theory, the speed of light, which is the limiting speed of any body having mass, is constant in all frames of reference. In the fifth paper that year, an exploration of the mathematics of special relativity, Einstein announced that mass and energy were equivalent and could be calculated with an equation, E=mc2.
Although the public was not quick to embrace his revolutionary science, Einstein was welcomed into the circle of Europe’s most eminent physicists and given professorships in Zurich, Prague and Berlin. In 1916, he published “The Foundation of the General Theory of Relativity,” which proposed that gravity, as well as motion, can affect the intervals of time and of space. According to Einstein, gravitation is not a force, as Isaac Newton had argued, but a curved field in the space-time continuum, created by the presence of mass. An object of very large gravitational mass, such as the sun, would therefore appear to warp space and time around it, which could be demonstrated by observing starlight as it skirted the sun on its way to earth. In 1919, astronomers studying a solar eclipse verified predictions Einstein made in the general theory of relativity, and he became an overnight celebrity. Later, other predictions of general relativity, such as a shift in the orbit of the planet Mercury and the probable existence of black holes, were confirmed by scientists.
During the next decade, Einstein made continued contributions to quantum theory and began work on a unified field theory, which he hoped would encompass quantum mechanics and his own relativity theory as a grand explanation of the workings of the universe. As a world-renowned public figure, he became increasingly political, taking up the cause of Zionism and speaking out against militarism and rearmament. In his native Germany, this made him an unpopular figure, and after Nazi leader Adolf Hitler became chancellor of Germany in 1933 Einstein renounced his German citizenship and left the country.
He later settled in the United States, where he accepted a post at the Institute for Advanced Study in Princeton, New Jersey. He would remain there for the rest of his life, working on his unified field theory and relaxing by sailing on a local lake or playing his violin. He became an American citizen in 1940.
In 1939, despite his lifelong pacifist beliefs, he agreed to write to President Franklin D. Roosevelt on behalf of a group of scientists who were concerned with American inaction in the field of atomic-weapons research. Like the other scientists, he feared sole German possession of such a weapon. He played no role, however, in the subsequent Manhattan Project and later deplored the use of atomic bombs against Japan. After the war, he called for the establishment of a world government that would control nuclear technology and prevent future armed conflict.
In 1950, he published his unified field theory, which was quietly criticized as a failure. A unified explanation of gravitation, subatomic phenomena, and electromagnetism remains elusive today. Albert Einstein, one of the most creative minds in human history, died in Princeton in 1955.
ART, LITERATURE, AND FILM HISTORY
1958
First Gold Record awarded to Perry Como for “Catch a Falling Star”
For as long as most people have been buying popular music on records, tapes and compact disks, the records, tapes and disks they’ve bought have carried labels like “Certified Gold!” and “Double Platinum!!” Those labels have been in use since the early days of the rock-and-roll.
CRIME
1964
Jack Ruby sentenced to death for murdering Lee Harvey Oswald
Jack Ruby, the Dallas nightclub owner who killed Lee Harvey Oswald—the accused assassin of President John F. Kennedy—is found guilty of the “murder with malice” of Oswald and sentenced to die in the electric chair. It was the first courtroom verdict to be televised in U.S.
GREAT BRITAIN
1991
Birmingham Six released from prison
In the face of widespread questioning of their guilt, British authorities release the so-called “Birmingham Six,” six Irish men who had been sent to prison 16 years earlier for the 1974 terrorist bombings of two Birmingham, England, pubs.
INVENTIONS & SCIENCE
1924
Mack Truck founder killed in car crash
John “Jack” Mack, who co-founded Mack Trucks, Inc.—then known as the Mack Brothers Company—with his brothers Augustus and William, is killed when his car collides with a trolley in Pennsylvania on March 14, 1924. After the Mack brothers sold their company to investors in 1911.
U.S. PRESIDENTS
1967
JFK’s body moved to permanent gravesite
On March 14, the body of President John F. Kennedy is moved to a spot just a few feet away from its original interment site at Arlington National Cemetery. The slain president had been assassinated more than three years earlier, on November 22, 1963.
CRIME
1950
The FBI debuts “10 Most Wanted Fugitives” list
The Federal Bureau of Investigation institutes the “Ten Most Wanted Fugitives” list in an effort to publicize particularly dangerous fugitives. The creation of the program arose out of a wire service news story in 1949 about the “toughest guys” the FBI wanted to capture.
COLD WAR
1990
Mikhail Gorbachev elected president of the Soviet Union
The Congress of People’s Deputies elects General Secretary Mikhail Gorbachev as the new president of the Soviet Union. While the election was a victory for Gorbachev, it also revealed serious weaknesses in his power base that would eventually lead to the collapse of his Regime.
AMERICAN REVOLUTION
1776
Alexander Hamilton is named captain of artillery company
On March 14, 1776, Alexander Hamilton receives his commission as captain of a New York artillery company. Throughout the rest of 1776, Captain Hamilton established himself as a great military leader as he directed his artillery company in several battles in and around New York.
