How Did Otto Hahn Greatest Impact

Thesis: The uses of nuclear energy range from being a clean, renewable energy source to cutting edge medical procedures.

On April 12, 1945, President Roosevelt’s death occurred. Harry Truman appropriated the project and the Secretary of War brought him up to date since he was always unaware of the task at hand. President Truman convened with Winston Churchill and Joseph Stalin and the Potsdam Declaration was written. This declaration offered Japan the opportunity to surrender or risk “prompt and utter destruction” Japan declined and President Truman was left with the decision to release nuclear destruction on Japan. On August 6, 1945, “little boy” the first atomic bomb was dropped on Hiroshima. Truman had picked the target based on the lack of American civilians in the area. Japan refused to surrender. Three days later “fat boy” the second atomic bomb was released on Nagasaki, the residency of the Mitsubishi factory that produced the torpedoes that bombed Pearl Harbor. The devastation and deaths were felt for months after the bombing. The staggering amount of deaths were reported to be between 90,000-146,000 people in Hiroshima and 39,000-80,000 in Nagasaki. Half of these deaths occurred on the days of the bombings. Japan surrendered to the United States. World War II would be ending.

The discovery of nuclear fission in 1938 concluded that with this knowledge the second World War outcome could be determined if the Nazi’s had the ability to create a nuclear bomb. One of the scientists that discovered nuclear fission, thought if

In the late 1930s, global tensions crystallized into war and a quest for a new super-weapon quietly began around in the world in numerous, underfunded laboratories. As Europe crumbled under the might of the Axis powers, American scientists began to explore the possibilities of nuclear fission in warfare.

David Hahn was a Michigan schoolboy who set about trying to build a fast breeder reactor in his garden shed. Having educated himself by reading Popular Mechanics and the Golden Book of Chemistry Experiments, he wrote off as a certain Professor Hahn for technical advice and help in obtaining radioactive materials. What he could not get from laboratory suppliers, universities, hospitals and nuclear agencies, he made himself. and how he was fascinated by science. While David was working on his “Atomic Energy” badge for Boy Scouts, his attention soon turned to nuclear energy. As you read on in the book you will soon begin to learn that David was really big into blowing things up and trying to make new chemicals;

In the fall of 1939, President Franklin D. Roosevelt responded to warnings from Albert Einstein and other scientists that Germany was attempting to develop an atomic bomb. Roosevelt’s reaction to this news was to allocate federal funds to a top-secret atomic bomb program, which became known as the Manhattan Project (History.org). After physicists were able to control the nuclear chain reaction at one of the sites, the project continued to advance at a breakneck speed. After the final bill was assessed for the project, the Manhattan Project cost nearly Two-Billion dollars and employed 120,000 Americans (Grant). By the summer of 1945, scientists watched on as they tested the world’s first atomic bomb; however, these scientists were unprepared for the result as the explosion was visible from 200 miles away, a 40,000 foot cloud was created, and a half-mile wide crater was produced (History.org). After releasing a cover-up story, word reached President Truman that the project was successful and the world had entered a nuclear age. The development of nuclear weapons in the Manhattan Project was culminated in the bombing of Hiroshima and Nagasaki. On August 6, 1945, President Truman announced to the nation “Sixteen hours ago an American airplane dropped one bomb on Hiroshima and destroyed its usefulness to the enemy. That bomb had more power than 20,000

Looking down across the vast landscape of Japan, massive skyscrapers reaching for the heavens fill the horizon illustrating the strength and potential of the nation. However, on August 6th, 1945, one man’s invention would bring this powerful nation to its knees. The brilliant mind responsible for the atomic mushroom cloud that enveloped the city belonged to a lanky, beanstalk-looking man from New York named Julius Robert Oppenheimer, who later became known as “the father of the atomic bomb.” Robert Oppenheimer affected society in a positive way through his work in the Manhattan Project during World War II, his advancements in the world of physics and through establishing some of the top science research facilities in the country.

ground breaking scientific knowledge. The knowledge of nuclear fission lead to: the ending of World

Leo Szilard was a Hungarian and moved to Berlin, Germany to become a physicist during the 1920’s – just around the time the Nazi’s came to power. As soon as Szilard realized what was going on in the country, he immediately left for Vienna and then to London. One day while resting, he thought up the process to nuclear fission. Although he had tried so many time to unlock the mystery of nuclear fission and failed so many times, in 1939 the problem was given a solution. However, Szilard was both excited and nervous at the results, as it could be a great source of energy or a fatal atomic bomb.

He helped design the Saturn V rockets. He created a liquid fuel that used alcohol and liquid oxygen to power the V-2. The first launch was on Sept 6, 1944 that was targeted for Pairs. Wernher von Braun has a PHD in physics. His lifelong dream was to send a man to the moon. He became the technical director of the U.S Army Ordnance Guided Missile Program. He had a brother

On August 6, 1945, an American plane, the Enola Gay, dropped an atomic bomb on the city of Hiroshima. The attacked killed approximately 150,000 Japanese citizens and two days later, a second atomic bomb was dropped on Nagasaki, killing an additional 75,000 Japanese. On August 14, 1945, the Japanese surrendered, ending the World War II, which lasted a dreadful six years (The Decision to Drop the Bomb). However, about five years earlier, the United States had no intentions of created a nuclear weapon until Albert Einstein and Enrico Fermi wrote a letter to President Roosevelt to warn the U.S. of the atomic technology being produced in the Axis countries. Roosevelt did not see the necessity for such a project, but he agreed to slowly proceed. In late 1941, the Manhattan Project, the code name for the American efforts to design and build an atomic bomb, was established. The project took place in Los Alamos, New Mexico and Robert Oppenheimer was put in charge of putting the pieces together. In total, nearly two billion dollars had been spent of the development and research of the atomic bomb while employing over 120,000 Americans. Nearly five years later on July 14, 1945, at the Trinity Site in New Mexico, the world’s first atomic bomb was ready to test. The scientists who had put all their effort into making this nuclear weapon watched the major destruction

Otto Hahn, Lise Meitner, and Fritz Strassmann were experimenting with the idea to bombard the nucleus with neutrons to add more atomic mass to the atom. Their original hypothesis stated that the experiment would create Uranium. The Nazi regime began spreading their reign over Germany in the mid-1930s when Hitler was elected to office. While the Nazis gained more power Jews lost more freedom, so for Lise Meitner it became an unsafe environment to continue her research. Although Otto Hahn fought hard for Meitner’s job he was overruled by their boss. The German government restricted her from leaving, so in 1938 she was smuggled into Sweden for her own safety. Hahn and Strassmann kept her updated on their findings, especially the one in particular result that puzzled them. While attacking the nucleus with neutrons the atomic number actually decreased and created barium. With the help of her nephew Otto

His most earliest works touched the subject of thermodynamics, he published many papers on this matter. The next problem that spiked his interest is radiation processes. He explained why and how it should be considered electromagnetic in nature. During these experiments he earned the name of Planck’s constant for the energy for a resonator of frequency. This was Planck’s most important work and was also a turning point in physics history. Even though all of this work was hard to accomplish, none of it was appreciated at the time. After his work gained some fame he wrote two books titled “Thermodynamics” and “Theory of Heat Radiation”. The first work was written in 1897 and the second in 1906. These works alone gave a basis for many theories and experiments. Max Planck finally was awarded his Nobel Prize in Physics in 1918. He was elected to Foreign Membership of the Royal Society in 1926, then was awarded their Copley Medal in 1928. The National Socialist Party put Planck through rough times as they ravaged on throughout Germany. Berlin actually became a city highly regarded for its Theoretical Physics, before the Nazis. His home was bombed towards the very end of the war. Many don’t remember Max for his ability to perform music or even possess any musical talent. At a certain point of his life, he believed it to a career of sorts.Max had many

Now that you know how Alfred Nobel became famous, I will tell you how the result of his experiments along with the legacy he left behind affected our society.

Young Rudolf Diesel was sent to Augsburg by his father to live with his cousin in order to continue the education, which he was able to have in France. He was enrolled in the Königlichen Kreis-Gewerbsshule where it provided outlets for all his deepest interests; there was a chemistry laboratory, a workshop equipped with a forge and machine tools and a municipal art gallery.” By his fourteenth birthday he had decided to become an engineer.” (Grosser p11)
