...Niels Bohr Physicist Niels Bohr 1885 – 1962: Niels Bohr was born in Copenhagen, Denmark on October 7, 1885 and died November 18, 1962. Bohr was best known as the Danish physicist who won 1922’s Nobel Prize. His father was Christian Bohr, Professor of Physiology at Copenhagen University, and his mother was Ellen Bohr. For recreational activity, he was a passionate football player. Niels Bohr Education: In 1903, he entered Copenhagen University to study physics. He received his Master's degree in Physics in 1909 and his Doctor's degree in 1911. While still a student he was awarded a gold medal from the Danish Academy of Sciences and Letters, for his "experimental and theoretical investigation of the surface tension by means of oscillating fluid jets." Professional Work & Awards: As a post-doctoral student, Niels Bohr worked under J. J. Thomson at Trinity College, Cambridge and studied under Ernest Rutherford at the University of Manchester, England. Inspired by Rutherford's theories of atomic structure, Bohr published his revolutionary model of atomic structure in 1913. In 1916, Niels Bohr became a professor of physics at the University of Copenhagen. In 1920, he was named director of the Institute of Theoretical Physics at the University. In 1922, he was awarded the Nobel Prize in Physics for recognition of his work on the structure of atoms and quantum mechanics. In 1926, Bohr became a Fellow of the Royal Society of London and received the Royal Society Copley Medal...

...Niels Hedrik David Bohr Niels Hendrik David Bohr was one of the foremost scientists of the 20th century. The Nobel prizewinning physicist was known for his development of the theory of atomic fission that led to the development of the atomic bomb. He was born on Oct. 7, 1885, in Copenhagen, Denmark. His father, Christian, was a professor at the University of Copenhagen and his brother, Harold, was a great mathematician. Bohr and his family grew up in an atmosphere that helped the development of his knowledge. His father was largely responsible for awakening his interest in physics while, his mother came from a family well known in the field of education. After Gammelholm Grammar School in 1903, he entered Copenhagen University where He won a gold medal from the Royal Danish Academy of Sciences for his theoretical analysis of vibrations of water jets as a means of determining surface tension. He received his Master's degree from the University of Copenhagen in 1909 and his doctorate in 1911 with a thesis Studies on the electron theory of metals. Bohr went to England to study with Sir J.J. Thomson at Cambridge. He had intended to spend his entire study period in Cambridge but he did not get on well with Thomson so, after a meeting with Ernest Rutherford in Cambridge in December 1911, Bohr moved to Manchester in 1912. There he worked with Rutherford's group on the structure of the atom. Rutherford became Bohr's role model both for his personal and scientific qualities. Using quantum...

...Jae Hyeon Park Mr. Tyc Calculus October 30, 2013 Faust in Copenhagen Faust in Copenhagen is story about seven physicists goes to small gathering of the group in Copenhagen and learn much more about themselves and their friends. In the group there were Lise Meitner, female, who is one of the high rank in field of experimentalist. Niels Bohr, Paul Dirac, Werner Heisenberg, and Wolfgang Pauli are the one of the top 10 in country’s physicists’ rank. While they may be the one of the top ten scientists they were also a professor mentored generations of future scientist. In Faust in Copenhagen they mention many of the famous physic equation such as relativity by Einstein, one of the most famous scientists in history. During the meeting in Copenhagen these talented scientist came up with Copenhagen interpretation where it was much more like relativity theory made by Einstein but it was ironed out with group of people struggling to complete the theory. On top of finishing Copenhagen interpretation Pauli, Heisenberg, Dirac, and other has created an inventions it led to implements that affect our life still to these day, activities and tools for future research. Ever since beginning of gathering all the physicists have different points of view and throughout the story the protagonists of the book will resolve around conflicts that would sometime contain love, respect, or theory that they have created. The story of Faust in Copenhagen mostly describes around six scientists who came...

Estaba a punto de poner un cero a un estudiante por la respuesta que había dado en un problema de física, pese a que éste afirmaba rotundamente que su respuesta era absolutamente acertada. Profesores y estudiantes acordaron pedir arbitraje de alguien imparcial y fui elegido yo. Leí la pregunta del examen y decía: “Demuestre cómo es posible determinar la altura de un edificio con la ayuda de un barómetro”. El estudiante había respondido: “Lleva el barómetro a la azotea del edificio y átale una cuerda muy larga. Descuélgalo hasta la base del edificio, marca y mide. La longitud de la cuerda es igual a la longitud del edificio”. Realmente, el estudiante había planteado un serio problema con la resolución del ejercicio, porque había respondido a la pregunta correcta y completamente. Por otro lado, si se le concedía la máxima puntuación, podría alterar el promedio de sus de estudios, obtener una nota más alta y así certificar su alto nivel en física; pero la respuesta no confirmaba que el estudiante tuviera ese nivel. Sugerí que se le diera al alumno otra oportunidad. Le concedí seis minutos para que me respondiera a la misma pregunta pero esta vez con la...

...Physics pre-assessment research task 1. Describe de Broglie’s proposal that any kind of particle has both wave and particle properties De Broglie suggested that if light can behave as both a wave and as a photon, particles could also have dual character. He proposed that all particles had wave properties as well as particle properties. He proposed that the wavelength is inversely proportional to the momentum of the particle, now known as the de Broglie wavelength of a particle and given by, λ=hmv. λ= Wavelength of light (m) h= Planck’s constant 6.626 x 10^-34 (J) m= Mass of the particle (kg) V= Speed of the particle (light) mv= Momentum of particle (kg m/s) 2. Define wave diffraction and interference Diffraction-is the bending of waves as they pass around the corner of a barrier or as they move through obstacles such as a slit. Wave interference is the phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium. Destructive interference is a type of interference that occurs at any location along the medium where the two interfering waves have a displacement in the opposite direction. For instance, when a sine pulse with a maximum displacement of +1 unit meets a sine pulse with a maximum displacement of -1 unit, destructive interference occurs. This is depicted in the diagram below...

...Max Blanck was just an ordinary man that came from a traditional family. His great- grandfather and grandmother were theology proffessors, and his father was a law professor. During his young school years he became a student of Hermann Muller, a mathematician that taught him astronomy and mechanics along with mathematics. This is when Planck first got an interest in physics and learned the principle of conservation of energy. He began the studies in 1874 at the University of Munich and studied theoretical physics. After he graduated, he taught math and physics briefly. Planck completed his habilitation thesis and began lecturing in Munich without getting paid becuase he was waiting to be offered a new postion. He also furthered his work on the field of heat theory. Planck then became a professor at Berlin University and joined the Physical Society. As far as Plancks home life goes, he married and had four children. He was friends with theologian Adolf con Harnack and his home soon because a social center. Famous scientists like Albert Einstein and Otto Hahn all frequently visited. His wife died and he remaired and had his third son. Planck's two sons and two daughters all died. By the end of the 1920s, Bohr, Heisenberg, and Pauli had worked out the interpretation of quantum mechanics, but Planck rejected it. He expected that wave mechanics would render the quantum theory, even though this can not be the case. Further work only cemented quantum theory, even against...

...en fascination og kærlighed til kusinen Agathe, og det ender med, at hun bliver den afgørende faktor for, at han ikke forlader gården, da hans tilværelse der ellers ikke er særlig god. Agathe er gift med Niels Bryde, og har ikke de samme følelser for Henning, som han har for hende. I skjul går Henning rundt rundt og begærer Agathe samtidigt med, at han hader Niels, da Henning mener Niels står i vejen for Agathe, så Agathe ikke kan opdage kærligheden, han tror der er i mellem dem. I forsøget på at drive Agathe og Niels fra hinanden, lyver Henning over for Agathe, hvor han fortæller hende, at Niels har været hende utro. Hun tror dog ikke på dette og ender med at slå ham, og forlader rummet med replikken: ”Henning, jeg vil sige Dig, jeg fortryder ikke hvad jeg har gjort”. Slaget rammer Henning, som et lyn og han begiver sig ind på sit værelse, hvor han kommer frem til, at han enten kan vælge at sætte en kugle for panden eller få hævn på Agathe for at have benægtet hans kærlighed til hende, men også for at lade ham leve et liv under elendige og rodløse forhold med troen om, at hun engang ville gengælde den kærlighed, han nærede for hende. Hennings kærlighed til Agathe bliver her erstattet med et ønske om at få hævn. På trods af deres fælles had til hinanden, går Henning og Niels en dag på jagt sammen. Vejret er dårligt og pga. tåge er sigtbarheden også dårlig. Nede i skoven går de hver sin vej rundt om en sø, og efter et stykke tid...

...theory of the atom Dalton’s Atomic Theory states in general: Matter is composed of atoms. Atoms cannot be divided or destroyed. Each element is composed of identical atoms. Atoms create a chemical reaction when they are rearranged. Physicist Joseph John (J.J.) Thomson discovered the electron after conducting experiments using a highvacuum cathode-ray tube to study electrical discharge. 1904 – “Thomson suggested a model of the atom as a sphere of positive matter in which electrons are positioned by electrostatic forces.” (Joseph John Thomson). 1913 – Niels Bohr introduced the model showing the electrons traveling in orbit around the nucleus of an atom. Bohr’s theory stating that photons are emitted when an electron drops from a higher-energy orbit to a lower one is the basis for quantum theory. Bohr’s model “is still commonly used and taught today as an educational simplification.” (Niels Bohr). On April 20, 2010 an explosion on the Deepwater Horizon oil rig caused 11 people to lose their lives and the sinking of the oil rig. An underwater camera discovered an oil leak within days of the explosion. Unfortunately, it took 87 days before the oil leak was contained. An estimated 3.19 million barrels (134 million gallons) of oil were leaked during the spill. 2010 was a year with several significant natural disasters Haiti –...

...hit the nucleus of the atoms. The rays were then reflected off as they hit the nucleus. This really intrigued Rutherford, and made him want to investigate on just what may have been making the rays bounce off. Later after that, in 1905 Albert Einstein made a great discovery of light absorption by atoms. He was able to write a large paper and conclude that atoms don’t only emit photons, but absorb them too. After Albert Einstein’s discovery another scientist was coming up with his own model. His model was subtly inspired by Rutherford's model, and he was almost as close to the model as the one we use today. This was the creation to Niels Bohr’s planetary model in 1915. Niels Bohr was a scientists who said that electrons can only stay on certain energy levels of the atom. He said that there are only a certain amount of electrons per level. Niels states that the higher the level, the higher amount of energy there is in that level of electrons. He also stated that the electrons were orbiting around the nucleus in a complex elliptical motion, similar to that of the sun. It wasn’t until the mid 1930s that the neutron was discovered! It was founded by James Chadwick when he was trying to calculate the mass of a neutral particle. The atomic theory had just kept changing and it really makes us wonder how much we think we know about todays models and knowledge of the atomic theory. Even in todays models we just recently discovered Quantum theory and quantum physics. Quantums also helped...
