Niels Bohr was a Danish scientist that was responsible for some major contributions to both physics and chemistry. Of course, like all most other scientists, Niels Bohr had some major influences in his life. Bohr made many contributions to science including two of his main contributions, his work with atomic structure and his quantum theory, along with other scientific work in the fields of chemistry and physics. Scientists are still learning about Bohr’s work today.
Neils Bohr is a very important role model to science because of all of his contributions to chemistry and physics. As a result of one of his contributions, Bohr won a Nobel Prize for his work on the structure of atoms in 1922 (“Neils Bohr- Biographical”). Other Examples of Bohr’s work include: the atomic model, the liquid droplet theory, and the quantum theory. Bohr was one of the few scientists to first observe the quantum theory. As a result of his observance of the quantum theory, he created the atomic model.
Bohr’s involvement to atomic structure was his most important piece of work. Bohr completed this theory of atomic structure in 1913 (“Niels Bohr.” Concordia). Bohr came up with this theory by using Rutherford’s idea of the atom and combining it with the quantum theory, which stated that an electron can be viewed in two different ways, either a particle or a wave (Palermo). Another name for Bohr’s atomic structure is the atomic model or the Bohr atomic model. The atomic model shows the atom as a small, positively charged nucleus surrounded by orbiting electrons (Palermo). This means that the electron does in fact orbit the nucleus but only does so in separate paths. When Bohr came up with the idea of the atomic model, he used his quantum theory a...

Although the atomic theory was developed in increments, George Johnston Stoney is most famous for contributing the term electron: fundamental unit quantity of electricity. Stoney would develop the concept fourteen years before he coined the term electron. He also made contributions to the theory of gasses, cosmic physics, and estimated the number of molecules in a cubic millimeter of gas.
In 1911, Ernest Rutherford found a very spectacular in such a small thing. Rutherford found that an atom has a microscopic charged nucleus. Empty space surrounds the nucleus. The nucleus is also surrounded by electrons. By this discovery Rutherford made the model of the atom.
Benjamin Banneker was an astronomer, scientist, mathematician, surveyor, clock-maker, author, and social critic. Most notable about his accomplishments was that despite racial constraints and little formal education, he was a self-taught man. By the end of his life, his achievements were well-known around the world.
...ven his son Aage N. Bohr, was awarded the 1975 Nobel Peace Prize for Physics for the collective model of the atomic nucleus. His Quantum theory and atomic model are both huge impacts in the world of modern chemistry and physics. Even to the day Niels Bohr died on November 18, 1962 he was dedicated to his Open-World Vision on the safety of atomic power between nations.
While still in his early twenties, he was among the handful of bright, young men who created quantum mechanics, the basic physics of the atom, and he became a leader of nuclear physics and elementary particle research. He is best known for his uncertainty principle, a component of the so-called Copenhagen interpretation of the meaning, and uses of quantum mechanics.
It is apparent that, during certain areas of history, the atomic models repetitively questioned as new material became available in the study of that field. Specific concepts begin to elevate themselves above others and become dominant as they begin being experimented on. Judging by the the literature on the development of the atomic model, the first speculations began around the ancient Greek and Roman times.
Dmitri Mendeleev was one of the most famous modern-day scientists of all time who contributed greatly to the world’s fields of science, technology, and politics. He helped modernize the world and set it farther ahead into the future. Mendeleev also made studying chemistry easier, by creating a table with the elements and the atomic weights of them put in order by their properties.
John Dalton was the first scientist to come up with an atomic theory, however there was a flaw in what he had initially believed. Dalton had a theory that atoms were indivisible and indestructible. J.J Thomson, also a scientist discovered electrons by using a cathode ray tube and showed the rays were negatively charged. Thomson recognized that Dalton’s accepted model of an atom did not consider particles being negatively or positively charged. Thomson then suggested a new model of the atom that was linked to plum pudding. The raisins in the pudding had represented the negative electrons and the positive charged electrons were shown through the dough. The electrons were believed to be on rotating rings throughout the atom. Thomson had abandon his other theory of “nebular atom” in which the atom was composed of immaterial vortices after using the new model. Although Thomson’s model of the atom proved some of the electrical properties of the atom due to electrons, the rest of the positively charged part of the atom was still ill-defined.
Benjamin Franklin, one of the most important Americans in history, did scientific work before 1790. He had a large impact on America as well as the rest of the world. Europe played a big part of his career because the influences he felt from Europe help him develop and work in science.
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.
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
Albert Einstein is possibly considered to be the greatest scientist of all time. He is well known for coming up with the theory of relativity described by the formula e=mc2, where energy is equal to mass times the speed of light squared. His accomplishments in physics helped start the nuclear age with nuclear weapons and power. Like most famous people he changed the world in a variety of ways. The most significant ways Einstein made the world a better place were his achievements in science, pacifism, and philosophical writings.
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...
