Biography Of Enrico Fermi


Enrico Fermi was an Italian-American nuclear physicist, who developed a self-sustaining chain reaction for the nuclear age in the year 1942. He was a major player in the development of the first atomic bomb and is referred to as the creator of the age of nuclear. Fermi excelled in theoretical physics as well as experimental physics. He won the Nobel Prize in physics in 1938 for his research on radioactivity induced. He contributed to quantum theory and mathematical analysis and nuclear physics, and particle Physics.


Life in the early years


Enrico Fermi was born in Rome on September 29, 1901. From an early age, he demonstrated an aptitude for maths and physical science. Self-taught, he was knowledgeable in quantum mechanics and nuclear physics, two areas that at the time were still in the early stages of development. At just twenty, he completed his Laurea degree, an Italian degree, following the submission of his thesis on X-ray Diffraction images. He traveled throughout Germany and Italy and met with leading scientists. The most notable of these was Albert Einstein. Fermi was among the first person to use Einstein’s famous formula ( E = mc 2) and become aware of the huge potential for nuclear energy inside the equation. In 1923, Fermi wrote

“It is not possible for at least the near future, to find ways to unleash these enormous amounts of energy. That’s to the good since the primary consequence of an explosion involving this massive amount of energy is to shatter into pieces the physicist that had the misfortune of figuring out the means to achieve it.”

It was a statement that was prophetic because the scientist who was a pity proved to be Fermi himself.

His first major contribution was a publication about statistical theory, which described the behavior of large quantities of particles, including neutrons, protons, and electrons. While this area of physics was not well-known in the beginning, however, it gained importance as the subatomic level of physics was created. The particles are now known as fermions.

In 1926, he was a full professor at the University of Rome. Although he was a renowned scientist, he was recognized as a great teacher who could present subjects clearly and simply. Fermi was a genius and he was also known to strive to simplify and utilize straightforward methods. If he could, he would make simple calculations first before using more complex math. Scientists attempt preliminary and apprehensive prediction using the ‘back of the envelope’ calculation, it’s referred to as the Fermi Method.

The year was 1928. He married Laura Capon, a science student at the university. They had two children: Nella as well as Giulio.

The year 1933 was when Fermi released his paper on the puzzling behavior of beta decay, which was the result of electrons being released from the nucleus in an atom. This was a puzzle from the point of view of the conservation of energy law. The research paper became an important element of particle physics and was later referred to as Fermi’s Interaction. It was also the precursor to the theory of weak interaction where the interaction between the proton-neutron and electron-antineutrino is mediated by a virtual W- W-boson.

The 1920s and 1930s were an era of rapid advances in subatomic Physics. In 1932, British scientist James Chadwick discovered the neutron (a sub-atomic particle without electric charge that is the nucleus of the atoms) Fermi experimented with bombarding chemical elements with neutrons. Fermi’s research showed that if neutrons can be reduced (by paraffin or water) in turn, they would be more readily taken up through chemical substances. This was a key element of nuclear reactors – the moderator, where protons moving at high speed are slow. In recognition of this work his work, he got Nobel Prize in 1938. 


The year 1929 was when the dictator of fascism Mussolini named Fermi in be a member of the Royal Academy of Italy; Fermi was a member of the Fascist party shortly thereafter likely as something he was required to do, not with enthusiasm. But in the year 1938 Mussolini enacted a string of anti-Semitic legislation to delight Hitler and banned Jewish individuals from working in government-owned institutions. This put many of Fermi’s staffers out of work, and also threatened his wife, who was Jewish. In December, he went together with his entire family to Stockholm to be awarded the Nobel Prize, he never returned to Italy however, he traveled in peace to the US in the US, where Colombia University was happy to be able to welcome the famous scientist.


The research on nuclear energy is conducted in the US


There are many reasons to be thankful for – both scientific and personal, it was a good time to escape fascist Italy and move to the US. After arriving in the US in 1938, he began to discover that there had been an important breakthrough in science in the form of the first examples that involved nuclear fission. Nuclear fission refers to a reaction that happens by the moment the nucleus of an atom breaks down into lighter, smaller nuclei. The experiment was performed by German scientists Otto Hahn and Fritz Strassman who had bombarded the uranium of their research with neutrons.

In the US prominent scientists like Niels Bohr and Enrico Fermi were excited about the possibility of harnessing nuclear fission power and the potential energy contained therein.

The next day, on the 25th of Jan 1939, a group of researchers from Columbia University including Enrico Fermi carried out the very first nuclear fission ever conducted in the US. They were also able to demonstrate that the uranium released more neutrons than they were delivered to the uranium suggesting that a chain reaction taking place. In recognition of the potential military benefits of this technology In March 1939, Fermi delivered an address at the Navy department regarding the possible use of nuclear energy. It had no immediate effect. However, when scientists submitted an unsigned letter from Albert Einstein to US President Roosevelt in which he stated that Germany might develop an atomic bomb, US attitudes changed. In the end, Roosevelt granted substantial funds for a secret project known as The Advisory Committee on Uranium – to improve nuclear capabilities for military use. fission.

Fermi’s initial task was to create an atomic pile made of graphite and enriched uranium which would allow a self-sustaining nuclear chain reaction could take place. Based on Fermi’s theoretical and scientific expertise, he constructed Chicago Pile I. Chicago Pile I – is within the 20-mile distance of the University of Chicago. The original nuclear reactor was located in an abandoned squash court that was located beneath the abandoned University of Chicago football stadium.

With Fermi’s careful analysis and planning it was constructed successfully making it the first nuclear reactor and announcing the dawn of the age of nuclear. Because the project was kept classified, a secret signal was sent out to Chairman, James B. Conant of the National Defence Research Committee.

“you’ll likely be intrigued to learn this: the Italian navigator just arrived within the world of the future.

Conant responded “Is this true? Were Natives friendly?”

“Everyone arrived safe and content.”

The accomplishment of this nuclear reactor led to the American government taking on the Manhattan project, which had unlimited resources as a high priority. For a time, Fermi stayed in Chicago where he pursued numerous groundbreaking nuclear experiments that were made possible by Chicago’s Chicago reactor.

But, by mid-1944 Robert Oppenheimer persuaded Fermi to directly join his group at Los Alamos, New Mexico.

Following the war, he continued to studies into various aspects of physics topics, including the origins of cosmic radiation. He also speculated on the possibility of alien life, resulting in the Fermi paradox. This is because although there is a chance that there could be extraterrestrial life on Earth, it is believed that we haven’t been able to recognize it. He also warned of the dangers of atomic as well as hydrogen bombs. Following the time that it was discovered that the Soviet Union developed a hydrogen bomb in 1949 He wrote:

“Such a weapon (hydrogen bomb) is far more than any military goal and is in the realm of huge natural disasters. Its very nature means that it isn’t limited to a specific military goal it becomes a weapon that practically is genocide in nature.”

(report to (report for Atomic Energy Commission 30 October 1949)

But, he took part in the plan to create hydrogen bombs for the US hydrogen bomb. He believed it was virtually impossible to stop technological advancement.

“One could be led to wonder if the scientists made the right decision in the present the leaders around the globe with this horrendous issue. There was no alternative. Once you have a basic understanding the attempt to prevent the development of this knowledge will be just as futile as trying to prevent the earth from rotating about the sun.”

The Collected papers from Enrico Fermi: The United States 1939-1954

Fermi often referred to the fact his observation that while Alessandro Volta studied electricity, the scientist was not sure of the direction it would take. For Fermi like many Atomic scientists, he was uneasy about the creation of nuclear bombs. A year before dying, he was in awe of the potential risks of this technology at the hands of the powerful.

“History of technology and science has repeatedly shown us that the advances of science in the field of fundamental understanding eventually led to industrial and technical applications that have changed our daily lives. It is highly unlikely that this quest to understand the structure of matter could be the exception to this principle. The only certain thing and something we all hope for is that the human being will eventually become mature enough to be able to fully utilize the powers he acquires to control nature.”

He died in 1954. was killed of stomach cancer, at just 53 years old.


In addition to Physics, his most loved activities were hiking, walking, and winter sports. He was a Roman Catholic, but his family was not particularly religious, and he remained an agnostic throughout his entire life. He was part of the American Philosophical Society, the American Physical Society, and the Sigma XI Honorary Scientific Fraternity.
