What was your family life like?
Mother: Ellen Adler came from a wealthy Jewish family famous in Danish banking and she was also involved in politicsFather: Christian Bohr, who was born on 1855 earned a doctorate (the highest degree awarded by a graduate school or other approved educational organization) and was a professor of physiology at the University of Copenhagen and was known for his work he physical and chemical aspects of respiration (Breathing), He earned his medical degree at 1878http://dwb.unl.edu/Teacher/NSF/C06/C06Links/207.138.35.143/nobel/macro/5000_79.htmlWhat other notable world events were occurring during your lifetime?
During his lifetime he has lived through both WW1 and WW2. Bohr had to leave Germany during the 1940’s, because the Nazi secret police were after to arrest him, because he was Jewish. As a result of leaving the country, he was told about the Manhattan Project, and was to keen work on it. What contributions in general did you make?

...uld cause harm to people so Bohr stopped from working on the atomic bomb to endorsing atomic energy. From the discovery of the atom structure other scientists found that by splitting the nucleus creates a massive amount of energy calculated to about 200 million volts. Later on scientists found out how to collect all that energy which led to the invention of nuclear power and power plants, which now acts as 6% of the amount of energy that is produced today https://sites.google.com/a/cssstudent.com/bio-of-niels-bohr/how-did-niels-bohr-affect-us-todayHow did your work aid in our understanding of the world?
How did it influence future scientists? Who was influenced?
He was one of the most influence people and influenced a German man that goes by the name Werner Heisenberg, a collage friend, that was one of the most important developers of quantum theory in the 1920
Enrico Fermi. Philanthropist and industrialist. In 1942, Fermi created the first self-sustaining nuclear power plant in an effort to provide clean energy for the world. Three years later in New Mexico, along with Einstein and many others, Fermi would design the plutonium fission bomb: a weapon intended to massacre millions at a time.
Oppenheimer's early studies were devoted mainly to energy processes of subatomic particles, including electrons,positrons, and cosmic rays. He also did innovative work on not only neutron stars but also black holes. His university provided him with an excellent opportunity to research the quantum theory, along with exploration and development of its full significance. This helped him train an entire generation of U.S. physicists. Furthermore, the most important impact was the invention of the atomic bomb.
Teller, who is a “Hungarian-born atomic physicist” and “known as the "father" of the hydrogen bomb”, was at the forefront when it came to the design of the Teller-Ulam Hydrogen Bomb (Hydrogen Bomb Exploded). Stanislaw Marcin Ulam, mathematician who developed the idea of the lithium hydride bomb, was the other half of that perfect combination. Although there was excitement for the U.S. being the first to be the bomb, some scientists did not share that excitement. Not all people agreed with the idea of building this bomb, some people had their doubts. For example, Julius Robert Oppenheimer was a highly known theoretical physicist and Director of the Los Alamos Laboratories.

Oppenheimer was the son of a German immigrant who had made his fortune by importing textiles in New York City. During his undergraduate studies at Harvard University, Oppenheimer excelled in Latin, Greek, physics, and chemistry, published poetry, and studied Oriental philosophy. After graduating in 1925, he sailed for England to do research at the Cavendish Laboratory at the University of Cambridge, which, under the leadership of Lord Rutherford, had an international reputation for its pioneering studies on atomic structure. At the Cavendish, Oppenheimer had the opportunity to collaborate with the British scientific community in its efforts to advance the cause of atomic research. Max Born invited him to Göttingen University, where he met other prominent physicists, such as Niels Bohr and Paul Dirac, and where, in 1927, he received his doctorate.
Enrico Fermi (1901-1954) succeeded in splitting the uranium atom and the Nobel Committee later awarded him the 1938 prize for physics. At Columbia University in New York, Fermi realized that if neutrons are emitted in the fissioning of uranium then the emitted neutrons might proceed to split other uranium atoms, setting in motion a chain reaction that would release enormous amounts of energy.(1) Fermi had succeeded in taking one of the first steps to making an atomic bomb.
Albert Einstein was one of these particular scientists. Although he was a pacifist, so his greatest effort in helping create the bomb itself was when he penned a letter to President Roosevelt, encouraging him to build the bomb in fear of what Germans had already done in 1938 (Sublette). But that being said, his contributions to science made creating the bomb possible. Through his Theory of
Nikola Tesla was a Serbian American inventor, electrical engineer, mechanical engineer and physicist. He was also considered an eccentric genius and recluse. Tesla is best known for his feud with Thomas Edison over AC power Versus DC Power. He was also well known for inventing the Tesla Coil which is still used in radio technology today. Nikola Tesla was mostly forgotten until the 1990’s when there was a resurgence of interest in popular culture.
First off Robert Oppenheimer started making the bomb when Poland was invaded by the Nazi’s. (Atomic Heritage) The Bomb or the Atom Bomb was created and then dropped at the Manhattan Project for testing. The Manhattan project was a success at the time. The making of the bomb meant that they could end the war. Oppenheimer said, “I am the destroyer of worlds”. Their really wasn’t any other any inventions that lead up to this invention. The discovery of Plutonium made the invention of the Atomic bomb more realistic to accomplish.(Atomic Heritage)
In 1939 rumor came to the U.S. that Germans had split the atom. The threat of the Nazis developing a nuclear weapon prompted President Roosevelt to establish The Manhattan Project. Oppenheimer set up a research lab in Los Alamos, New Mexico and brought the best minds in physics to work on the problem of creating a nuclear weapon. Although most the research and development was done in Los Alamos, there were over 30 other research locations throughout the project. After watching the first nuclear bomb test Oppenheimer was quoted as saying simply “It works.”.
To sum up, Robert Oppenheimer was always ill during childhood so turned to learning for relief but was commonly bullied. After exceeding in math and science, he went to Harvard University and got advanced degrees in Europe. Years later, his greatest accomplishment was building the atomic bomb in which he soon regretted. He foresaw it would start a competition between America and Russia to make the most powerful bombs. He was then taken to court for weakening America and communism. This lead to depression until his death on February 18,
Richard P. Feynman was born in 1918 in Brooklyn; in 1942 he received his Ph.D. from Princeton. Already displaying his brilliance, Feynman played an important role in the development of the atomic bomb through his work in the Manhattan Project. In 1945 he became a physics teacher at Cornell University, and in 1950 he became a professor at the California Institute of Technology. He, along with Sin-Itero and Julian Schwinger, received the Nobel Prize in Physics in 1965 for his work in the field of quantum electrodynamics.
Rutherford is a very popular chemist and physicist. Chemistry was greatly impacted by Ernest Rutherford, mainly through the gold foil experiment, which determined electrons are in empty space while also orbiting the nucleus of an atom.. Being one of the smartest chemists in history and being the first person to split an atom, In 1908 Rutherford was awarded the Nobel Prize. “(2010). Ernest Rutherford - Famous Scientists.

Scientists from earlier times helped influence the discoveries that lead to the development of atomic energy. In the late 1800’s, Dalton created the Atomic Theory which explains atoms, elements and compounds (Henderson 1). This was important to the study of and understanding of atoms to future scientists. The Atomic Theory was a list of scientific laws regarding atoms and their potential abilities. Roentagen, used Dalton’s findings and discovered x-rays which could pass through solid objects (Henderson 1). Although he did not discover radiation from the x-rays, he did help lay the foundations for electromagnetic waves. Shortly after Roentagen’s findings, J.J. Thompson discovered the electron which was responsible for defining the atom’s characteristics (Henderson 2). The electron helped scientists uncover why an atom responds to reactions the way it does and how it received its “personality”. Dalton’s, Roentagen’s and Thompson’s findings helped guide other scientists to discovering the uses of atomic energy and reactions. Such applications were discovered in the early 1900’s by using Einstein’s equation, which stated that if a chain reaction occurred, cheap, reliable energy could b...
Of all the scientists to emerge from the nineteenth and twentieth centuries there is one whose name is known by almost all living people. While most of these do not understand this mans work, everyone knows that his impact on the world is astonishing.
