Enrico Fermi (Italian: [enˈri.ko ˈfeɾ.mi]; 29 September 1901 – 28 November 1954) was an Italian physicist, best known for his work on Chicago Pile-1 (the first nuclear reactor), and for his contributions to the development of quantum theory, nuclear and particle physics, and statistical mechanics.He is one of the men referred to as the "father of the atomic bomb". Construction was completed on December 1 and the reactor went critical the next day.

At Argonne he continued experimental physics, investigating neutron scattering with Leona Marshall. [99][100], In mid-1944, Robert Oppenheimer persuaded Fermi to join his Project Y at Los Alamos, New Mexico. [54] In March 1934, Fermi wanted to see if he could induce radioactivity with Rasetti's polonium-beryllium neutron source. This paper was sufficiently well-regarded that it was translated into German and published in the German scientific journal Physikalische Zeitschrift in 1922. In 1933 the French husband-and-wife team of Frédéric and Irène Joliot-Curie discovered artificial radioactivity caused by alpha particles (helium nuclei). [81] But their work habits and personalities were different, and Fermi had trouble working with Szilárd. For this reason, Italian physicists were slow in embracing the new ideas like relativity coming from Germany. [14][15] With scientifically inclined friend, Enrico Persico,[16] Fermi pursued projects such as building gyroscopes and measuring the acceleration of Earth's gravity. What is less certain, and what we all fervently hope, is that man will soon grow sufficiently adult to make good use of the powers that he acquires over nature. Fermi, a charismatic, energetic, and seemingly infallible figure, clearly was the leader—so much so that his colleagues called him “the Pope.”. [147][148] This makes him one of 16 scientists who have elements named after them. So why haven't they come to Earth? Fascist Italy had just instituted anti-Jewish laws. [128], Fermi underwent what was called an "exploratory" operation in Billings Memorial Hospital in October 1954, after which he returned home. Enrico Fermi was born in Rome on 29th September, 1901, the son of Alberto Fermi, a Chief Inspector of the Ministry of Communications, and Ida de Gattis. [63][62], The Via Panisperna boys also noticed some unexplained effects. In 1938, Fermi was without doubt the greatest expert on neutrons, and he continued his work on this topic on his arrival in the United States, where he was soon appointed Professor of Physics at Columbia University, N.Y. (1939-1942). At the time, no one could have imagined the impact his scientific discoveries would have on the world. The panel agreed with the committee that atomic bombs would be used without warning against an industrial target. Lincei, 1935 (also in Z. One might have called him a benevolent dictator. As a person, Fermi seemed simplicity itself. He spent four years at the University of Pisa, gaining his doctor’s degree in physics in 1922, with Professor Puccianti. We have gathered a few of his quotes from his books, journals, talks, speeches, interviews and life in general. They had one son Giulio and one daughter Nella. When testing uranium they observed several activities, but they could not interpret what occurred. If this sounds like hyperbole, anything about Fermi is likely to sound like hyperbole". It seems to me improbable that this effort to get at the structure of matter should be an exception to this rule. Fermi decided to switch to experimental physics, using the neutron, which James Chadwick had discovered in 1932.

Enrico Fermi (Italian: [enˈriːko ˈfermi]; 29 September 1901 – 28 November 1954) was an Italian (later naturalized American) physicist and the creator of the world's first nuclear reactor, the Chicago Pile-1.He has been called the "architect of the nuclear age" and the "architect of the atomic bomb". The problem was traced to neutron poisoning from xenon-135, a fission product with a half-life of 9.2 hours. "It does not seem possible, at least in the near future", he wrote, "to find a way to release these dreadful amounts of energy—which is all to the good because the first effect of an explosion of such a dreadful amount of energy would be to smash into smithereens the physicist who had the misfortune to find a way to do it. Fermi did not believe that atomic bombs would deter nations from starting wars, nor did he think that the time was ripe for world government. Pauli later postulated the existence of an uncharged invisible particle emitted along with an electron during beta decay, to satisfy the law of conservation of energy. After this war he was appointed as the General Advisory of the Atomic Energy Commission.

He proceeded to work with tremendous enthusiasm, and directed a classical series of experiments which ultimately led to the atomic pile and the first controlled nuclear chain reaction. In beta decay, or the expulsion of a negative electron from the nucleus, energy and momentum seemed not to be conserved. [58][60][61], The natural radioactivity of thorium and uranium made it hard to determine what was happening when these elements were bombarded with neutrons but, after correctly eliminating the presence of elements lighter than uranium but heavier than lead, Fermi concluded that they had created new elements, which he called hesperium and ausonium. He paced off the distance they were blown by the explosion, and calculated the yield as ten kilotons of TNT; the actual yield was about 18.6 kilotons. [18], Fermi graduated from high school in July 1918, and at Amidei's urging applied to the Scuola Normale Superiore in Pisa. [11] Giulio died during an operation on a throat abscess in 1915[12] and Maria died in an airplane crash near Milan in 1959. [98], In September 1944, Fermi inserted the first uranium fuel slug into the B Reactor at the Hanford Site, the production reactor designed to breed plutonium in large quantities. He died in Chicago on 28th November, 1954. Fermi’s father, Alberto Fermi, was a chief inspector of the government railways; his mother was Ida de Gattis, a schoolteacher. published in the book series Les Prix Nobel. Enrico Fermi was a renowned nuclear physicist. In 1918 Enrico Fermi won a scholarship to the University of Pisa’s distinguished Scuola Normale Superiore, where his knowledge of recent physics benefited even the professors. [125], Fermi wrote a paper "On the Origin of Cosmic Radiation" in which he proposed that cosmic rays arose through material being accelerated by magnetic fields in interstellar space, which led to a difference of opinion with Teller. Fermi's first major contribution involved the field of statistical mechanics. The neutrino was detected after his death, and his interaction theory showed why it was so difficult to detect. Fermi left Italy in 1938 to escape new Italian racial laws that affected his Jewish wife, Laura Capon. After bombarding thorium and uranium with slow neutrons, he concluded that he had created new elements or entities. He won the Nobel Prize in 1938 for his work in radioactivity, allowing him to escape fascist Italy and settle in the United States. When he submitted his paper to the British journal Nature, that journal's editor turned it down because it contained speculations which were "too remote from physical reality to be of interest to readers". His experiments led to the first controlled nuclear chain reaction in Chicago, on December 2, 1942, under Chicago's athletic stadium.
During his teens, he and friends conducted physics experiments for fun, including testing the density of Rome's water supply. Before I came here I was confused about this subject. To further his commitment to his new country, Fermi and his wife became American citizens in 1944.

The fundamental point in fabricating a chain reacting machine is of course to see to it that each fission produces a certain number of neutrons and some of these neutrons will again produce fission. [37], In the introduction to the 1968 English translation, physicist Fred L. Wilson noted that:.mw-parser-output .templatequote{overflow:hidden;margin:1em 0;padding:0 40px}.mw-parser-output .templatequote .templatequotecite{line-height:1.5em;text-align:left;padding-left:1.6em;margin-top:0}, Fermi's theory, aside from bolstering Pauli's proposal of the neutrino, has a special significance in the history of modern physics. Since there were only three students in the department—Fermi, Rasetti, and Nello Carrara—Puccianti let them freely use the laboratory for whatever purposes they chose.
This seminal work brought Fermi an invitation in 1926 to become a full professor at the University of Rome.

[50] Thus Fermi saw the theory published in Italian and German before it was published in English. He received his early education from a local grammar school and at a young age developed a great interest in physics and mathematics. [52][53] By March, Fermi's assistant Gian-Carlo Wick had provided a theoretical explanation using Fermi's theory of beta decay. This work resulted in the discovery of slow neutrons that same year, leading to the discovery of nuclear fission and the production of elements lying beyond what was until then the Periodic Table. It is clear that the use of such a weapon cannot be justified on any ethical ground which gives a human being a certain individuality and dignity even if he happens to be a resident of an enemy country. Tasked with a mission to manage Alfred Nobel's fortune and has ultimate responsibility for fulfilling the intentions of Nobel's will. F Division had four branches: F-1 Super and General Theory under Teller, which investigated the "Super" (thermonuclear) bomb; F-2 Water Boiler under L. D. P. King, which looked after the "water boiler" aqueous homogeneous research reactor; F-3 Super Experimentation under Egon Bretscher; and F-4 Fission Studies under Anderson.
