This report serves to state the findings that arose from investigating Young’s double-slit experiment. One point that the reader should look forward to is an explanation of the interference effect. It is also interesting to note the importance of Young’s work in relation to the development of light-wave theory.
Throughout history, philosophers and scientists have debated whether light acts as a particle or a wave. In the seventeenth century, Dutchman Christiaan Huygens’ optic research insinuated that light was wave-like. This motion is akin to the ripples seen atop a body of water once an object is dropped in. In Treatise on Light (1690), Huygens’ Principle explains that wavefronts are distributed so that the extent of the wavelets lie between the geometric parameters drawn from its light source. Meanwhile in England, Isaac Newton had been conducting his prism experiments to further understand light and color. Newton’s corpuscular theory approaches the nature of light as a stream of particles. Because of Newton’s influence, particle theory was widely accepted by the scientific community. Nearly a century later, Thomas Young, an English physician and physicist, was intrigued by light’s dilation after it had passed through a thin slit. He then set out to discover the mysterious properties behind light.
While Newton’s observations were sufficient enough for a macroscopic environment, they did not correctly anticipate the results on a much smaller scale. Young challenged the standard particle theory in the early nineteenth century. Young understood that sound traveled in waves. He recalled that when two sound waves interfered under the right conditions, they canceled out. The Englishman then hypothesized that this interference effect ...

...as a wave, it would act as a wave. But, when the light was measured as a particle, the wave property of interference ceased. This was coined the observer effect. A French scientist Louis-Victor de Broglie defined light as both a particle and a wave. Even with recent experiments, such as Feynman’s controlled double-slit electron diffraction, there still remains much more to learn about the characteristics of light.
From researching Young’s double slit experiments, one can learn about the complexities of light. The interference effect, for example, indicates wave-like motion. Furthermore, wave theory’s historical background played a role in Young’s hypothesis formulation. Similarly, the results of the experiment impacted the unfolding of modern wave theory. In short, the double slit experiment is evidence that light can display both particle and wave-like qualities.
As America heads into a new year, we find our government tightening its purse strings and cracking down on excessive spending, with an emphasis on the US military. According to author Brad Plumer, a reporter at the Washington Post, “U.S. defense spending is expected to have risen in 2012, to about $729 billion, and then is set to fall in 2013 to $716 billion, as spending caps start kicking in.” Pared with a more drastic 350 billion dollar cute going into effect over the next ten years, the military finds itself cutting what cost the most to maintain and support troops (Fact Sheet par. 2). In recent years the military has bolstered an overwhelming 1,468,364 troops (Active Duty). These numbers are to be cut substantially; the biggest cut is to be seen in the Army. The Army must deal with a reduction of 80,000 troops, cutting its force of 570,000 troops to nearly 140,000.Subsequently, the budget cuts, which have led to a reduction of troops in the military, has driven the military to turn to advanced weapons technology that requires less people to m...
The cost of the personnel has increased to nearly an unsustainable rate since 2000. Wartime funding was increased over inflation but the personnel has dropped. That being said, the defense spending in 2015 will be about $600 billion or 3.24 of the GDP. The defense budget pays into not only base defense, but also to veterans, civilian and foreign military aid. Each of these expenditures go into the percentage that the government is allocating to defense. Contrary to popular opinion, the money does not strictly go to weapons and military personnel. Health and care for military and veterans alike is on the rise. Retiree pay and benefits comprise the DOD spending for veterans. As discussed, funding for defense is important when it comes to sustaining our country and being a competitor for war
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.
Once coming up with a defense policy, it is important that we define the existing threats in the world so that we minimize the potential chances for failure. There are many threats in the international community that could make success of these policies very difficult. Such issues as the threat of nuclear war and the threat of shortages of natural resources could make implementation of these policies virtually impossible. Along with recognizing the threats to the Unites States from the international community, it is important that we not neglect the internal issues that could threaten the U.S. as a superpower. Recognizing this, it is important to makes sure that the United States maintains a strong economy.
Will the security of our nation be compromised? Will U.S. enemies take it as a chance to land a brutal blow against America? Yes, these things will happen. However, they will only happen if the military budget is decreased too much, or if funds are not used appropriately. For instance, maybe the U.S. needs to invest less of its resources into meddling into foreign affairs. At some point, America became the terrorists in the “War on Terror.” Undoubtedly, America has the strongest and best-trained military on the planet. Mainly because of how many resources we’ve invested in building it. Granted, this great country will not falter with some military budget cuts here and there. Instead, it can take those funds and invest them into the leaders and workforce of tomorrow and brighten its
National defense is a sensitive topic to most because we need it to live in our country as safe as we do, but it is a big problem in our national debt. The Washington Post showed that the United States spends 20% of its budget on defense and it has increased dramatically since the tragedy of 9/11 (“America’s Staggering Defense Budget”, Plumer). America spends more on its military than the next 13 nations combined, which...
Additionally, this book tackles an extremely difficult topic that is considered to be one of the most complex subjects in higher learning. Feynman is undaunted by this, he takes the known principles of physics and presents them in a new light, and should be praised for his ability to demonstrate such a complicated subject to so many people in such a way that even the common man can grasp these basic principles of physics. Thus, Richard Feynman’s book Six Easy Pieces is more than worthy of achieving high literary merit.
This is not the intention of the use of the word in quantum physics. Quantum particles are, instead, representations of the actions and reactions of forces at the sub-atomic level. In fact, physicists are less concerned with the search for a material particle underlying all physical objects and more interested in explaining how nature works. Quantum theory is the means that enables the physicist to express those explanations in a scientific way. 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.
Before opticks was introduced as the accepted Paradigm, scientist struggled to come up with their own evaluations, which often led to instability. It was not till after they accepted Newton’s theory that scientist were able to do
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.
Throughout different experiments, scientists have discovered that light behaves as both a wave and a particle in different circumstances. The only way that all of the properties of light can be explained is through the idea of a wave-particle duality.

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.
In 1801 Thomas Young provided some very strong evidence to support the wave nature of light, he placed a monochromatic light in front of a screen with two slits cut into it, and observed an interference pattern, only possible if light was a wave. In 1965 Richard Feynman came up with a thought-experiment that was similar to Young’s experiment. In Feynman’s double-slit experiment, a chosen material is fired at a wall which has two small slits that can be opened and closed at will – some of the material gets blocked and some passes through the slits, depending on which ones are open.
