Ronan Hurley 11/26/17 Chemistry H Ms. Solman Niels Bohr Niels Bohr was a man who was born in Copenhagen in the year 1885, on the 7th of October. Niels Henrik David Bohr was already in the clear to be a strong influence to the scientific community. Bohr was raised in an educated family, where his parents his parents had him always studying and working hard so that he would be doing his best all of the time. His father, Christian, was a teacher in Physiology where he taught at the Copenhagen University. Niels mother Ellen Adler had also come from a strong and determined family in the field education. His father, Christian was largely responsible for opening up the minds to his immense interest in physics while still at school. After matriculation (an exam you take to be able to enroll at a college or university, current day SAT and ACT,) at the Gammelholm Grammar School in 1903, Niels enrolled at Copenhagen University. Whilst there he came under the guidance of Professor C. Christiansen, who was a well-known original and highly endowed physicist. He took his Doctor’s degree in 1911 and his Master’s degree in Physics in 1909. This was definitely the beginning of his career, and from here on he only grew in his knowledge and as an overall person more and more every day. In the 20th century he won a gold medal for the solution of a certain scientific problem, which then gave him the idea to take up this experimental and hypothetical investigation of the surface tension by means of oscillating fluid jets. Bohr created the Bohr model of the atom, where he found that the energy levels of electrons were appointed of a separate entity and that the electrons which were surrounding the atom move around in stable orbits around the atomic nucleus. These electrons can move from one energy level to a second or previous energy level. Although other models have replaced the Bohr model, its main ideas are still used today. He created the idea of complementarily which says that items could be distinctively checked by means of two separate properties, which is like behaving as a wave or a stream of particles. For ex. the notion of complementarily took over Bohr’s thoughts in both fields of philosophy and science. Bohr, in the end birthed the Institute of Theoretical Physics. This can be found at the University of Copenhagen, which would now be known as the Niels Bohr Institute, it was in fact opened in the year 1920, under Bohr’s name. Bohr taught and worked with important and influential physicists including, George de Hevesy, Hans Kramer, Werner Heisenberg and Oskar Klein. He thought that the birthing of this new and improved zirconium-type element, which was named hafnium (element number 72), after the Latin name for Copenhagen, where it was then discovered. In the future, the element Bohrium was eventually named after him. The hafnium came from deep Latin roots. In the late 1930’s Bohr saved Jews from Hitler and his Nazi’s. After the Germans had taken over Denmark, Bohr held a well-known conference with the heisenberg, whom then, at that time, had become the top dog, to the German project of nuclear weapons. In late 1943, word had spread and eventually gotten into Niels knowledge that he was going to be detained by the Germans, so, he obviously needed to escape them. After finding out about this information he leaves for Sweden. Once he was there, Bohr was taken to England, where he was brought into thee British Tube Alloys project of nuclear weapons. Here, Bohr was a large piece to the Manhattan Project. Once WWII was over, Niels wanted International Cooperation on nuclear energy. Bohr was heavily partnered with the creation of C.E.R.N. He was also partnered with the R.E.R.D.A.E.C. Bohr eventually became the head chairman of the N.I.T.P. in the year 1957, for atomic physics, the Rutherford–Bohr model or Bohr model which also been called the Bohr diagram, brought in by Niels Bohr his partner Rutherford in the year 1914, depicts the atom as a tiny, positively charged nucleus which is surrounded by electrons which travel in circular orbits around the nucleus. This is similar to the structure of our solar system which consists of our planets, except with attraction given off by static forces rather than gravity. In conclusion Bohr had some amazing contributions to the world of science and chemistry and his ideas and models and everything in-between are still being used today and are still being talked about today due to the mass footprint that he left on the society of science. From being born into a well, educated family to working with great scientists and then continuing to have 6 children who would live in his shadows I would say that he did a pretty good job. From working with some of the great names in the scientific community, to be becoming one of the great names. He is a massive influence and a great role model to many scientists in the world.
