Free Essays on The Never Ending Night

In the autobiographical novel Night by Elie Wiesel, the young teenager Elie underwent the transformation from a boy who had faith and honored his God to a man who no longer believed in that God. Elie was a Jewish boy who lived in a small Hungarian town called Sighet, during World War II. When Elie was fifteen, Germans invaded Hungary and sent all his friends and family to concentration camps. During this devastating time in his life, Elie saw a great deal of inhuman deeds done to the Jews by the Germans and he started to lose faith in God. By the time he was finally liberated, he was starved, lost most of his family, and lost all faith in the Jewish God. There are many examples in the beginning of Night where people are trying to keep and strengthen their faith but there are many more examples of people rebelling against God and forgetting their religion. The first example of Elie loosing his faith is when he arrived at Auschwitz. Elie and his father are directed to go to the left. A prisoner then informs them that they are on their way to the crematory. Elie’s father recites the Kaddish or prayer for the dead. Revolt rises up inside of Elie and he questions God. â€Å"Why should I bless His name? The Eternal, lord of the Universe, the All-Powerful and Terrible, was silent. What had I to thank Him for?† (Wiesel 31). Another example of prisoners in the concentration camp loosing their faith in Night is when the pipel, a young child, was hung in front of the whole camp. The pipel was the Oberkapo’s servant. The Oberkapo was the leader of the fifty-second unit. He never struck or insulted the prisoners who worked under him ,that is why the prisoners loved him . Even though most pipels were cruel and hated, this one had the face of a sad angel and was loved by all. The Oberkapo was suspected in the intentional explosion of Buna’s electric power station. He was transferred to Auschwitz but the pipel was left behind. The pipel refus...

Understanding Quantum Optics

Understanding Quantum Optics Quantum optics is a field of quantum physics that deals specifically with the interaction of photons with matter. The study of individual photons is crucial to understanding the behavior of electromagnetic waves as a whole. To clarify exactly what this means, the word quantum refers to the smallest amount of any physical entity that can interact with another entity. Quantum physics, therefore, deals with the smallest particles; these are incredibly tiny sub-atomic particles which behave in unique ways. The word optics, in physics, refers to the study of light. Photons are the smallest particles of light (though it is important to know that photons can behave as both particles and waves). Development of Quantum Optics and the Photon Theory of Light The theory that light moved in discrete bundles (i.e. photons) was presented in Max Plancks 1900 paper on the ultraviolet catastrophe in black body radiation. In 1905, Einstein expanded on these principles in his explanation of the photoelectric effect to define the photon theory of light. Quantum physics developed through the first half of the twentieth century largely through work on our understanding of how photons and matter interact and inter-relate. This was viewed, however, as a study of the matter involved more than the light involved. In 1953, the maser was developed (which emitted coherent microwaves) and in 1960 the laser (which emitted coherent light). As the property of the light involved in these devices became more important, quantum optics began being used as the term for this specialized field of study. Findings Quantum optics (and quantum physics as a whole) views electromagnetic radiation as traveling in the form of both a wave and a particle at the same time. This phenomenon is called wave-particle duality. The most common explanation of how this works is that the photons move in a stream of particles, but the overall behavior of those particles is determined by a quantum wave function that determines the probability of the particles being in a given location at a given time. Taking findings from quantum electrodynamics (QED), it is also possible to interpret quantum optics in the form of the creation and annihilation of photons, described by field operators. This approach allows the use of certain statistical approaches that are useful in analyzing the behavior of light, although whether it represents what is physically taking place is a matter of some debate (although most people view it as just a useful mathematical model). Applications Lasers (and masers) are the most obvious application of quantum optics. Light emitted from these devices is in a coherent state, which means the light closely resembles a classical sinusoidal wave. In this coherent state, the quantum mechanical wave function (and thus the quantum mechanical uncertainty) is distributed equally. The light emitted from a laser is, therefore, highly ordered, and generally limited to essentially the same energy state (and thus the same frequency wavelength).
