What exactly is light? Is it a wave? Is it a particle? Is it a mythical being? This question has been debated on for many centuries. Some claimed it was a wave. Others claimed it was a particle. In the early nineteenth century, Isaac Newton proposed that light was made up of particles, but the answer was not agreed on until an experiment performed by Thomas Young. Young’s basic experiment consisted of a coherent light source such as a laser beam being shot through and illuminating a plate containing two parallel slits and being observed on a screen located behind the plate. What exactly were the results of this historical experiment?
Young’s experiment showed that light behaves with characteristics of both a particle and a wave. He observed that as the light source passed through the slits and was projected onto the screen, it diffracted and it produced an interference pattern, or a series of bright and dark lights on the screen. If light contained the characteristics of a classical particle, as some like Isaac Newton suggested, then the light would not have interfered when passing t...
Both 1984 and The Handmaid’s Tale are dystopian novels, however, these books are a lot more complex than mere portrayals of dystopia, it can be argued that they are explorations of dystopia rather than mere portrayals. In order to explore dystopia, many themes must be considered, such as; feminism, love and repression. Nonetheless, it is apparent that human characteristics are the driving point of the two novels, predominantly, the depiction of human resilience. In an imperfect world, it is important to have certain qualities which, if plentiful, it can mean success, whereas if it lacks, it can mean failure, this characteristic is resilience. The protagonists in each novel, Winston in 1984 and Offred in The Handmaid’s Tale face situations which leave them both in disarray, and both even consider suicide. The authors tentatively highlight human resilience, its limits and most importantly its strengths into the two novels.
“‘They score! Henderson has scored for Canada!’” Foster Hewitt wordlessly described” (Pelletier) when Paul Henderson scored the series-winning goal. This allowed Canada to win the 1972 Summit Series, a moment that no one would ever forget since it all happened during the climax of the Cold War. Prior to this, the Soviets had won the previous three Olympic gold metals since Canada could not use its NHL players. Thus, this provided Canada with the chance to play hockey against the USSR using its best players. This raised the question: if Canada were able to send its best players, would it still be enough to beat the Soviets? Everyone in Canada was certain that the Soviets would not win a single game, but little did they know they underestimated the extent of the Soviets abilities. Tied in the last few minutes of game eight, Canada had to score or they would lose the series. However, when Paul Henderson scored the game-winning goal, never before had a single sporting event meant so much to Canadians. Therefore, Paul Henderson’s goal is a defining moment for Canada in the twentieth century becauseit provided Canada with the opportunity to evolve hockey, proved that Canada and our democratic society were superior to the USSR and their communist society, and brought citizens together to unify Canada as a nation.
The Hunger Games was a critically acclaimed movie when it came out; however, some critics would argue that the movie can be sometimes too violent for its intended audience. In this essay I would dissert Brian Bethune’s essay “Dystopia Now” in order to find its weaknesses and compare the movie Battle Royale with his essay.
Scott Hightower’s poem “Father” could be very confusing to interpret. Throughout almost the entirety of the poem the speaker tries to define who his father is by comparing him to various things. As the poem begins the reader is provided with the information that the father “was” all of these things this things that he is being compared to. The constant use of the word “was” gets the reader to think ‘how come the speaker’s father is no longer comparable to these things?’ After the speaker reveals that his father is no longer around, he describes how his father impacted him. Details about the father as well as descriptions of the impacts the father has distraught on the speaker are all presented in metaphors. The repetitive pattern concerning the speaker’s father and the constant use of metaphors gives the reader a sense that the speaker possesses an obsessive trait. As the reader tries to interpret the seemingly endless amount of metaphors, sets of connotative image banks begin to develop in the reader’s mind. Major concepts that are expressed throughout the poem are ideas about what the speaker’s father was like, what he meant to the speaker, and how he influenced the speaker.
The Grand Mosque of Córdoba remains to this day, one of the finest mosques, of that which once was part of the west of the Islamic Umayyad Caliphate. Córdoba was once the capital and seat of the Umayyad Caliph in Spain; then known as Al-Andalus. As such, this city was graced in the days of Islamic Rule by the building of a mosque; a most fundamental part of any Islamic city. If one were to think of Spain now, Islam is of course not the first thought that would usually come to mind. Spain is, after all, a Christian land with a deep Roman Catholic history, and the location of many Christian Pilgrimage destinations. Thus, one would be forgiven for thinking that the Islamic Empires had probably never even reached as far as West Europe. The Grand Mosque of Córdoba tells a different story.
“You never really understand a person until you consider things from his point of view – until you climb into his skin and walk around in it.” Harper Lee identifies many charcters in the beginning of this book. She was very descriptive of all the characters in the beginning of the book. Each character was described from Scout’s point of view. Throughout the book, Lee lets the reader see some of the characters in their natural environments. They are still written through Scout’s eyes, but instead of passing by them on the sidewalk, Scout is in their home sitting with them, or hearing personal stories about them. Three of these characters that Scout points out specifically are Jem Finch, Aunt Alexandra, and Tom Robinson.
The author tells of how waves are effected by quantum mechanic. He also discusses the fact that electromagnetic radiation, or photons, are actually particles and waves. He continues to discuss how matter particles are also matter, but because of their h bar, is so small, the effects are not seen. Green concludes the quantum mechanics discussion by talking about the uncertainty principle.Chapter 5: The need for a New Theory: General Relativity vs.
“I'm a romantic; a sentimental person thinks things will last, a romantic person hopes against hope that they won't.” F. Scott Fitzgerald said this and it is very apparent that he feels this way in The Great Gatsby. In this novel filled with the experiences of a group of supercilious, rich, white people, Fitzgerald shows this with the many symbols he uses throughout the novel. Among the most arresting are the Green Light at the end of the Buchanan’s dock, which Gatsby envies for, the color white, which deceives readers with Daisy’s deceitful beauty, and the Eyes of T.J. Eckleburg, which sees all wrong done by the characters.
Quantum mechanics describes several objects and phenomena that seem strange and are difficult to understand. Among these are quanta “chunks” of energy; the wave-particle duality of matter; and the uncertainty principle which limits what we can know about objects. In 1927, German physicist Werner Heisenberg discovered a general characteristic of quantum mechanics, the uncertainty principle. According to this principle, it is impossible to precisely describe both the location and the momentum of a particle at the same time, therefore it affects the attempts to measure a particle’s location and
Modern science is based on material, experimental evidence, but if matter is non-material as the physicist's fundamental forces suggest, then it will not be able to explain what matter is. It can only explain how nature works by observing the effects on material objects. In his book In Search of Schrödinger's Cat ch. 8, Gribbin suggests the possibility that no particle is real until it is observed. The act of observation collapses the wave function so that one of a number of ghost particles becomes a real particle. This idea has similarities with idealism and its appearance and reality arguments. Gribbin does not take the argument forward so let us consider the philosophical arguments instead of the physics.
According to the de Broglie relation and Bragg's law, a beam of 54 eV had a wavelength of 0.167 nm. The experimental outcome was 0.165 nm via the grating equation, which closely matched the predictions. Davisson and Germer's accidental discovery of the diffraction of electrons was the first direct evidence confirming de Broglie's hypothesis that particles can have wave properties as well.
Stemming from the first years of the 20th century, quantum mechanics has had a monumental influence on modern science. First explored by Max Planck in the 1900s, Einstein modified and applied much of the research in this field. This begs the question, “how did Einstein contribute to the development and research of quantum mechanics?” Before studying how Einstein’s research contributed to the development of quantum mechanics, it is important to examine the origins of the science itself. Einstein took much of Planck’s experimental “quantum theory” research and applied it in usable ways to existing science. He also greatly contributed to the establishment of the base for quantum mechanics research today. Along with establishing base research in the field, Einstein’s discoveries have been modified and updated to apply to our more advanced understanding of this science today. Einstein greatly contributed to the foundation of quantum mechanics through his research, and his theories and discoveries remain relevant to science even today.
Light is a photon , which are tiny particles of light, however photons have electrons and protons which behave like waves and particles based on their given charge, this is the wave-particle duality. There is no clear distinction. When light behaves like a wave it responds to a particles electron frequency. When discussing frequency we are referring to light 's wavelength which is based on light 's energy.When the frequency
For instance, throughout the nineteenth century, it was correctly believed that light was a wave. If light were a wave like all other waves, it must have a medium through which to propagate through. This medium was called the ether, a substance which was everywhere throughout the universe. If this hypothesis were true one would be able to calculate the velocity of the Earth through the ether. Many experiments were conducted to determine this velocity the most famous one being the Michelson-Morley experiment.
During the seventeenth century, the modern science of physics started to emerge and become a widespread tool used around the world. Many prominent people contributed to the build up of this fascinating field and managed to generally define it as the science of matter and energy and their interactions. However, as we know, physics is much more than that. It explains the world around us in every form imaginable. The study of physics is a fundamental science that helps the advancing knowledge of the natural world, technology and aids in the other sciences and in our economy. Without the field of physics, the world today would be a complete mystery, everything would be different because of the significance physics has on our life as individuals and as a society.
