1831- Using his invention the induction ring, Michael Faraday proved that electricity can be induced (made) by changes in an electromagnetic field. Faraday’s experiments about how electric current works, led to the understanding of electrical transformers and motors. This experiment became Faraday’s Law, which became one of the Maxwell Equations (Administrator, 2007). 1890 - Heinrich Hertz (1857-1894) a German physicist, laid the ground work for the vacuum tube. He laid the foundation for the future development of radio, telephone, telegraph, and even television.
1. developed the theory of relativity, he was a mathematician and he’s greater known in theoretical physics. 2. One of the two pillars of modern physics the “alongside quantum mechanics”. 3. He is mostly known for his mass–energy equivalence formula E = mc2, which has been recognized as "the world 's most famous equation".
J. Robert Oppenheimer Imagine how famous you would be if you were intelligent enough to help hundreds of scientists and physicists assemble nuclear weapons? Physicist J. Robert Oppenheimer must have felt the same way During World War II. Julius Robert Oppenheimer was born on April 22, 1904, in New York City. He was known as "The Father of the Atomic Bomb" because of his assistance with assembling nuclear weapons during World War II. He is also known for the Born-Oppenheimer Approximation; the assumption that the electronic motion and the nuclear motion in molecules can be separated.
Harold Urey - Experiment Harold Urey’s discovery of deuterium is perhaps his most revolutionary discovery. Not only did Urey receive a Nobel Prize for his work towards hydrogen-2, deuterium would go on to become invaluable both to chemists’ understanding of the elements, and the field of chemistry as a whole. Urey’s pursuit of deuterium began in 1931, after his interest was piqued by a scientific journal that discussed the supposed existence of the isotope. Using the Balmer series, which is the series of lines in the hydrogen atomic emission spectrum, Urey and a colleague by the name of George Murphy, calculated where hydrogen-2’s emission lines should be located. They determined that the isotope’s emission lines would be “redshifted” (shifted
In addition to electricity, Tesla experimented with radio waves and much of Guglielmo Marconi’s, inventor of the radio, work was based off of Tesla’s research. Throughout his life, Tesla was granted 111 U.S. patents and every electrical appliance today uses at least one of Tesla’s inventions. In addition to how Tesla affected the world, Einstein left his mark on America’s technology and inventions. One major invention Einstein contributed to was the atomic bomb. The invention of the atomic bomb was a turning point in World War 2 when they dropped the bombs on the cities of Hiroshima and Nagasaki.
In his book, he used history as a medium to show that “that scientific progress depended more on the accumulation of “new facts” that anyone could discover than on the theoretical insights of a few men of genius”- John G. McEvoy. In his work with electricity, Joseph Priestley anticipated the inverse square law of electrical attraction, discovered that charcoal conducts electricity, and noted the relationship between electricity and chemical change between the two. Through the basis of these experiments, he was elected a member of the Royal Society of London in
Enrico Fermi and Leo Szilard created the first nuclear pile in Chicago, 1942 (Roleff 54). Some of the greatest minds in physics collaborated together to create the bomb. The project was put under command of Leslie Groves, and the U.S. Army Corps of Engineers (Beyer 37). The amount of funding as well as political support provided to the Manhattan Project gave the researchers the ability to make technological breakthroughs at unfathomable frequencies. Only two years went by between the construction of the first nuclear reactor and the first detonation of the atomic bomb.
Linus Pauling played an important role in the pioneering in chemistry. In matter of fact he received a Nobel Prize in 1954 and also in 1962. The Nobel Prize in 1962 was for the development of quantum mechanics during the 1920s. His Nobel Prize in 1954 was for his research in nature of the chemical bond and its application to the elucidation of the structure of the complex substance . Linus Pauling was born in Portland, Oregon.
In this letter Einstein wrote about a new study on the chain reactions that took advantage of uranium. He said if done correctly it could produce substantial amounts of power, and if this power was harnessed it would result in a bomb capable of unheard of damage. Einstein also stated that it was believed that the German government
The film Einstein and Eddington unfolds the story of how Arthur Eddington contributed to Albert Einstein’s General Theory of Relativity. Einstein was the one who first introduced the concept of relativity, but Eddington was the one who finished the theory by proving Einstein’s claim. It all started when Eddington found out an anomaly with the behavior of Mercury; that Mercury’s behavior is against Newton’s theory. Eddington used Mercury as a counter example to disprove Newton’s theory. He consulted Einstein about this because Einstein’s theory seems to justify Mercury’s behavior and not the theory of Newton.
