The Stern-Gerlach experiment: Spin Doctors at Work
The stern-Gerlach experiment aimed at concluding which model better described the structure of an atom; the classical model proposed by Rutherford, or the Bohr model. This experiment is one of the most important in modern history, it brought together the quantum physics up until its creation and solidified quantum theory. This paper analyses the Stern-Gerlach experiment by investigating the physics leading up to its creation, the intentions and expectations of performing the experiment, the conclusion that Stern and Gerlach made, what actually happened, and what has come of the results.
In the early 1900’s much was becoming known about atoms, and theories of their quantum nature was slowly beginning to become accepted among the scientific community. The idea of quantisation had gained a lot of traction due to fundamental experiments that were being developed along with the theory explaining them. In 1887, Heinrich Hertz discovered that the electric discharge between two electrodes was enhanced if the negative electrode was illuminated …show more content…

This experiment is known as the Stern-Gerlach experiment. Stern and Gerlach hoped to prove that the quantum theory was correct by showing that the orbital angular momentum of electrons in an atom was spatially quantised (10). The quantum theory stated that an orbiting electron will give rise to a magnetic moment which is proportional to the orbital angular momentum of the electron, so therefore by measuring this magnetic moment; it is possible to prove this idea of space quantisation (10). Sommerfeld’s theory acted as the enabling theory for the experiment, providing an approximate size of the magnetic moment the atoms should experience

The Manhattan Project: James Chadwick And The Atomic Bomb

868 Words | 4 Pages

As flapper girls with chic haircuts kicked off their dancing shoes, the night and the roaring twenties coming to an end, a tall, slender Englishman by the name of James Chadwick sat hunched over in his lab, working to find a particle that no one, not even the world’s most brilliant minds of his time, was sure existed. His name was James Chadwick and for nearly a decade, he had been trying to prove the existence of neutral particles in the nucleus of the atom, neutrons. As the new decade began, Chadwick still had no tangible evidence proving his neutrons, and maybe he never would have if not for the work of Irene and Frederic Juliot-Curie. The two scientists had performed an experiment where they bombarded alpha particles at beryllium, producing

Once upon a time, a young boy was given up by his father to three spinsters. The young boy, not knowing what his father was doing, stayed with the spinsters. The young boy soon realized that his father would never come back again. He was filled with the feelings of abandonment and loneliness. After they deliberated for a moment they decided that the best way to raise him was to teach him how to spin.

At the center of the AoK is the process of testing hypotheses through empirical inquiry (). The knowledge produced must be able to withstand the test of experience and development – leaving the AoK susceptible to several pivotal shifts of thinking throughout history (Klein, Peter). In quantum physics, one such moment was the proposal and discovery of the up, down, and strange quarks by physicists Murray Gell-Mann and George Zweig from 1964-1968 (Brown, John). However, it was not until 1977 that all six quarks were empirically observed (Brown, John). The case study demonstrates the young age of the discipline of quantum physics, and perhaps how it affects the presumption of axiomatic knowledge.

What follows is the explanation and the study of one of the key experiments that shock all the physicists. The results of the double slit experiment of Thomas Young were completely unpredictable and the interpretations have a deep philosophical touch. In all cases, the answer to a why question it starts with a maybe. Like never before, the basic concepts of physics did not prove to be universally applicable. The tiniest particles not even visible with the most powerful microscope seemed to have a mind of their own.

Physics made lightning progress in the twentieth century. From 1912, Alfred Wegener suggests that all continents were originally gathered in one: the Pangea cracked into derived blocks (the tectonics theory plates). The discovery of the terrestrial radio business eventually validates the theory, disputed at the time. On 12/14/1900, Max Planck introduces his quantum theory to the Berlin Physical Society.

In 1911 Ernest Rutherford and his team directed a beam of positively charged particles at a thin sheet of gold foil. If Thomson’s model was correct, the beam would pass through the foil. The team predicted that some of the beams of particles would bend, but not drastically. This was because scientists believed that positive charges were spread out in gold atoms. When they conducted the experiment, most particles passed through the sheet, but some particles were deflected, and bounced right back.

This was known as the “plum pudding” model. Ernest Rutherford put his hypothesis to the test in 1911 when he conducted the gold foil experiment. During this experiment, Rutherford blasted a sheet of gold foil with alpha particles and to his surprise, a few particles were rebounded and deflected back. This lead to his conclusion that there was a nucleus in the center of each atom which was causing the deflection of the particles. Rutherford once said, “We are rather like children, who must take a watch to pieces to see how it works”.

The electrons pattern changed simply by being observed. Such a strange finding had to be replicated, so in 2002 another team of researchers attempted to do the same thing faster at a smaller scale. There was no way for the electron to “know” it was being observed. The insertion of the measuring device took only 40ns while it would take 160ns for the information about the

For the time independent case, the Schrodinger equation takes the form ((-ħ^2)/2m ∇^2+V(r))ψ(r ⃗ ) = Eψ(r ⃗ ) (1.7) Where E are the energy eigenvalues. Many applications of quantum theory have led to successful models of nuclear physics and as a consequence, many physical phenomena can now be described using quantum interactions.
