article, “What Happened in Copenhagen?: A Physicist's View and the Playwright's Response,” Pais argues the historical accuracy of Michael Frayn’s 1998 play, Copenhagen. Frayn’s play depicts a meeting that took place in 1941 between prominent physicist Niels Bohr and Werner Heisenberg. The play takes place is the Nazi occupied Denmark, and sheds light on the political issues both men are facing. Following Pais’s dispute regarding small details of the play, Frayn then gives his response to Pais’s…

Theory Newspaper Article Honors Chemistry 6 October, 2014 Quantum Atomic Model at it Again Over the past centuries the quantum atomic model has been a coveted title of the scientific community. From John Dalton, J.J. Thomson, Ernest Rutherford, Niels Bohr, all the way up to the current quantum-mechanical model. What makes all of these scientists such a pivotal part of science after all? The quantum atomic model is one of the most important discoveries and innovations of all sciences. In this…

This essay going to be about an atom. Atom is always around us all the time and ever object are made out of an atom. We, humans, are also made of the atom. Knowing about the structure and what it really is a very important thing to learn as a student. In order to learn about an atom, we will have to understand about Democritus first. So who is Democritus? Democritus is the first human to ever come up with the first atomic theory. Democritus was born in Greece around 460BC. He has a life spend…

Thomson, Ernest Rutherford, Niels Bohr, and more. But, Werner and Erwin discovered electrons moved in unpredictable ways, and could only be explained by intricate math problems (Erwin Schrodinger-Biographical,2015) (Werner Heisenberg-Biographical, 2015). This model has gathered information…

In 1913, physist Niels Bohr explained for the first time ever how the atom released specific amounts of light each time: the electrons are orbiting around the large positive charge fast. Niels bohr said that electrons could only occupy specific energy levels as they orbit the nucleus, so he came up with the diagram called bohr (Absorb Learning, 2008); bohr diagrams. The following years, many scientists put an experiment together that would…

Somewhere in between the years of 460 BC and 370 BC a man named Democritus first introduced the idea of an atom. He was the first person to say that everything is made of atoms. He also said that atoms are indestructible and that the changes we see in substances are just the atoms moving. Democritus said that the shape of the atoms give substances different properties. Democritus’ work, however, did not survive through the Middle Ages. Democritus had no real evidence to prove his theory, but he…

Mark Frayn’s Copenhagen takes us on an historical sleuth adventure that is performed by the ghosts of Danish physicist Niels Bohr, his colleague and “adopted son” Werner Heisenberg, and Bohr’s wife Margrethe. Heisenberg was an overall boyish companion of Bohr who would go on long walks and talk physics to. However, the mystery is when Heisenberg visited the Bohrs in Copenhagen in 1941. The play explores the meeting and discusses different topics, such as building atomic bombs, escaping Nazi…

The Manhattan Project was a project that produced the first nuclear weapons during World War II. It all started when Einstein found out the Germans were working on a new and more powerful weapon for war. Einstein wrote a letter to the president which helped initiate the effort to build an atomic bomb. In December 1941 the government launched the Manhattan project. The project was originally named Development of Substitute Materials. It included over 30 different research and production…

discovered how to create an atomic bomb. Hahn discovered nuclear fission by having a speed neutron hit a uranium atom, the uranium atom spit. When the speeding neutron hit the nucleus of the uranium atom the atom stretched until it split. Before this, Niels Bohr had a theory that a nucleus must be “like a wobbly droplet of liquid.” Hahn discovered that this theory was indeed accurate. When Hahn split the atom there was enough energy to make a grain of sand jump, but he was curious to see if…

The Decline of Deutsche Physik Contextual Analysis of the Exodus of German Physicists in the Early Twentieth Century “So we see that we cannot attach any absolute signification to the concept of simultaneity, but that two events which, viewed from a system of co-ordinates, are simultaneous, can no longer be looked upon as simultaneous events when envisaged from a system which is in motion relatively to that system” In 1905 German physicist Albert Einstein published the first paper of a new…
