Space and TIme Essay Example for Free

Space and TIme Essay Many people wish that they could go back in time and change something that they have done; even if it was a small mistake, or a large one that changed their life forever. Science is trying to prove that time travel does exist using the Space-time continuum. With controversy on both sides, scientists have proven that the space-time continuum does exist; however time travel is still up for debate. How Space-time was created For a long time we saw space and time as two separate entities. Many very sound theories existed before the space time theory came about. Some of those theories were Isaac Newton’s theories of mechanics and James Clerk Maxwell’s theories on electromagnetism. Though these theories never quite agreed with each other. For some time before this light was known to be an electromagnetic phenomenon, but never followed the laws of mechanics as matter does. This prompted Albert A. Michelson and many others to study light itself. Their studies showed that â€Å"light always traveled with the same velocity, regardless of the speed of its source† (Overduin, 2007 para 1) It was latter discove red that the speed of light was an unsrupassable speed limit on the universe; meaning nothing can travel faster than the speed of light which is 299,792,458 meters per second. Though none of these phycistest were able to put the whole story together. At the young age of 16, Albert Einstein often wondered what it would be like to travel along a ray of light. By 1905 Einstein proved that light must move at a constant speed no matter the speed of the source transmiting it. For this to be correct space and time can no longer be independent. Although Einstein did all this ground work on proving space-time he did not put them together.

Nuclear Energy :: Essays Papers

Nuclear Energy It seems that the world as a whole is in search of an energy source that is cleaner, cheaper, and more efficient. This seems to be particularly true in the United States where the government seeks to separate themselves from their reliance on petroleum from countries including those in the Middle East. Their agenda, unfortunately, is less concerned with environmental issues than it is with issues of power, money, and dominance. Either way, nuclear energy has emerged as the forerunner for alternative energy sources. Today, there are 109 nuclear power plants in the United States which contribute roughly 20% of the power used in the United States(Nuclear Energy, April 13, 2005). Nuclear fission is performed by fusion of hydrogen into helium. This is done using uranium, plutonium, or thorium and placing them in the reactor, which start a chain reaction that can produce vast amounts of energy. Uranium is the element primarily used in reactors. The fission of a single atom can produce 10 million times the amount of energy that an atom can produce that is burned from coal. Uranium is an abundant element which is easily found and extracted. It often has to undergo a relatively cheap refining process, however, as the isotopes are found mixed in nature. Nuclear fission is also relatively clean, as there is no excess CO2 produced, as there is in the burning of coal and petroleum. It does, however, have is pollutants. The filtering rods used have to be changed every two years and the o ld rods disposed of. Because the rods are highly radioactive, their disposal must be dealt with meticulously. Currently most of the rods are shipped to Yucca Mountain (The Bane of Nuclear Energy, April 13, 2005). Despite the benefits of nuclear fission, the quest still continues for an even better energy source. The hopes of the new energy source are pinned on a process known as nuclear fusion. This is the process that takes place on the sun and other stars under intense heat and pressure. The hope is that nuclear fusion will become a reality here on earth as it will provide an unprecedented amount of energy very cheaply and with very little pollution.

Critical Criticism Of Julius Caesar - 942 Words

Written by Shakespeare in 1599, Julius Caesar has become one of most eye-opening pieces on power and the use and misuse of it. In this play, Julius Caesar is depicted as egotistical and easily swayed by other’s arguments that appeal to his pride or love of self-image, as seen in Act II, Scene II, when Calpurnia, Caesar’s wife, attempted to persuade Caesar to stay home after having dreams and seeing omens insinuating his impending death. Calphurnia’s argument temporarily convinced Caesar to grudgingly agree with her and stay at home, but soon after Caesar reluctantly complied, Decius, one of the conspirators in Caesar’s oncoming assassination, with pointed appeals, immediately convinced Caesar to overlook Calpurnia’s argument and to focus†¦show more content†¦Although Calpurnia did not fully take into account Caesar’s pride, she still created a potent argument and ended with an appeal to Caesar’s self-image. Asking Caesar to bl ame his absence on her, Calpurnia begged, â€Å"call it my fear that keeps you in the house and not your own†, drawing away attention from what others in the Capitol might think of Caesar’s leave, which happened to be one of the first problems Decius mentioned when dissecting the â€Å"flaws† in Calpurnia’s argument. Overall, Calpurnia’s argument did not fail in convincing Caesar to stay at home; in fact, it succeeded at first. Although Caesar only begrudgingly agreed, he still, at his wife’s urging, decided to not go to the Capitol, that is, until Decius, with hidden motives, persuaded him otherwise. Why was Calpurnia’s argument less compelling than Decius’? Several factors contributed to the ineffectiveness of Calpurnia’s argument following Decius’, such as the order that the two presented in and also gender. Calpurnia, not expecting a rebuttal from anyone else, did not solidify her argument, which Decius fully took advantage of after entering unannounced. Simply the fact that Decius presented his argument last and that his argument already appealed to what Caesar desired in the first place, which was to not stay at home, persuaded Caesar that Calpurnia’s arguments were faulty. Also, Calpurnia was not a man.Show MoreRelatedVictory or Demise, Same Faces in a New Light1520 Words   |  7 Pagescrushed by the hands of an oppressive government and trust is scarce.
