  • Ernest Rutherford - 747 words
    Ernest Rutherford Ernest Rutherford was born in New Zealand in 1871 as one of 12 children. It was Rutherford who first "split" an atom and who discovered the atomic "nucleus", a name that he invented. For this he is regarded as the greatest experimental physicist of his time. Rutherford was one of the first and most important researchers in nuclear physics. Soon after the discovery of radioactivity in 1986 by the French physicist Antoine Henri Becquerel, Rutherford discovered the three different types of radiation. By covering his Uranium with thin foils of aluminum, gradually increasing the number of foils. For the first three layers of foil the radiation escaping from the uranium decreased ...

    William Carlos Williams was born September 17, 1883 in Rutherford, N.J. His father had emigrated from Birmingham, England, and his mother from Puerto Rico. He was admitted in 1902 to the medical school of the University of Pennsylvania, where he met two poets, Hilda Doolittle and Ezra Pound. A long term friendship ensued between Pound and himself, such that Williams said he was able to divide his life into two distinct segments: Before Pound and After Pound.1 From 1906 to 1909 Williams did his internship in New York City, writing verse in between patients. His first book was published in 1909, just before a trip to Leipzig to study pediatrics. In the following years Williams wrote not only p ...

  • After The Reconstruction Years, Blacks And Whites Often Rode Together In The Same Railway Cars, Ate In The Same Restaurants, - 1,531 words
    After the Reconstruction years, blacks and whites often rode together in the same railway cars, ate in the same restaurants, used the same public facilities, but did not often interact as equals. The emergence of large black communities in urban areas and of significant black labor force in factories presented a new challenge to white Southerners. They could not control these new communities in the same informal ways they had been able to control rural blacks, which were more directly dependent on white landowners and merchants than their urban counterparts. In the city, blacks and whites were in more direct competition than they had been in the countryside. There was more danger of social m ...

    Antisocial Personality The Antisocial Personality is (APD) is a serious disorder that affects many males and cause a great threat to families, friends, and even complete strangers. Most personality disorders may cause an inconvenience to a person▓s family and friends, but usually harm themselves more than others. Antisocial Personality Disorder contrasts from other personality disorders because the defining trait is a predatory attitude toward other people (Smith, 1999). ⌠They have a chronic indifference to and violation of the rights of one▓s fellow human beings.■ (Alterman; Cacciola; McDermott; Mulholland; Newman; & Rutherford, 2000). A common tendency of those with ...

  • Atomic Theory - 703 words
    Atomic Theory Chemistry: A Brief History of Atomic Theory February 28, 1999 In the beginning of the 1800s John Dalton, an English scientist did work some work on gases, which lead him to the creation of a complex system of symbols for all known elements at the time. He took all the information he had collected, along with the Laws of Conservation of Mass, Definite Composition and Multiple Proportions and updated Aristotle's theory of matter with the Atomic Theory of Matter, which stated: - All matter is composed of tiny, indivisible particles called atoms. - Atoms of an element have identical properties. - Atoms of different elements have different properties. - Atoms of two or more elements ...

  • Atomic Theory - 1,225 words
    Atomic Theory In ancient Greek the word atom meant the smallest indivisible particle that could be conceived. The atom was thought of as indestructible; in fact, the Greek word for atom means not divisible. Knowledge about the size and make up of the atom grew very slowly as scientific theory progressed. What we know/theorize about the atom now began with a core theory devised by Democrotus, a Greek philosopher who proposed that matter consisted of various types of tiny discrete particles and that the properties of matter were determined by the properties of these particles. This core theory was then modified and altered over years by Dalton, Thompson, Rutherford, Bhor, and Chadwick. The ato ...

  • Atoms - 266 words
    Atoms The evolution of the modern atom model took several years to evolved with contribution from different scientists. One of these scientists, the first to come up with a modern model of the atom is JJ Thomson. Thomson proposes that the structure of an atom is mainly a sphere. A sphere that is filled with positive electronic field and contains tiny particles that has a negative charge. He called the tiny particles corpuscles. Thomsons model of the atom is often refer as the plum pudding model because it has a consistency that is all the same throughout the whole atom with a few plums to represent the tiny corpuscles. Thomsons modern was widely accepted by people all over the world. It was ...

  • Cats - 1,236 words
    Cats Many people today have pets for pleasure and companionship. Nearly any animal can be a pet, such as hamsters, rabbits, birds, fish, frogs, horses, and even cats and dogs. Besides being a loving companion, pets serve many other purposes as in protecting homes, destroying vermin, and providing a means of transportation. The elderly and the childless couples can rely on a pet as an emotional outlet. In addition, pets can be kept for their beauty, rarity, or for the beautiful sounds that birds can make. Today pets are usually purchased from breeders, pet shops, or animal shelters rather then individually captured and tamed. All pets were made domestic, including cats. Cats are the second mo ...

  • Cats - 1,226 words
    ... All types of cats come from the same, basic evolution. Cats are meat-eating, or carnivores, and great hunters; they have sharp, pointed teeth called canines and claws that can be retracted into their paws (Brown 1147). Cats have very keen senses, which allow them to stalk their prey. All cats have well-developed sight and very sharp hearing, which allows them to make successful hunting forays at dawn and dusk (Rutherford 14). Cats must be able to merge in with their environment, to flee the pursuer and pursue their target (Rutherford 18). Some characteristics of the cat outweigh others without competition. Cats have a strong sense of smell, which is used more for detecting and communica ...

  • Charles Russell And Jehovahs Witness - 1,071 words
    Charles Russell And Jehovah's Witness Charles Russell and Jehovahs Witnesses On February 16, 1852, a child was born that would grow up to lead millions of people astray from families, friends, Christianity, and, most importantly, a personal relationship with Jesus Christ. The teachings this child taught later as an adult lead people down a road that will only end in one destinationHell. On this seemingly normal day in 1852, just outside of Pittsburgh, Pennsylvania, a son was born to Joseph L. Russell and his wife, Anna Eliza. They named him Charles Taze Russell. This child would grow up to form The Watchtower Society and later the religious group Jehovahs Witnesses. Because Charles Taze Russ ...

    History Behind The Atom The History Behind The Atom Throughout the discovery of the atom, many scientists worked to formulate how the atom works. Which began in the early 1800s with John Dalton, to our current model of the electron cloud developed by Schrodinger. During this long process of the discovery the atom, took many models and scientists. The entire group of scientists who assisted in the discovery of the atom used each others model to improve each others theories. Firstly, John Dalton showed that, collectively, the three laws, the law of definite proportion, the law of conversation of masses, and the law of multiple proportion. These three laws demonstrate the existence of the atom. ...

    History Of Chemistry History of Chemistry Introduction: Humans have always been very curios creatures. The have always wondered about what they are and why they are here. Our limited knowledge of the environment has always urged for new things to be discovered. The desire to understand the world better has made people search for rational answers, for principles and laws. For centuries people have tried to unlock the mysterious world that surrounds them. History: Because myths did not explain things well enough the Greeks began to ask questions about the world around them. They did this so thoroughly and so brilliantly that the era between 600 and 400 B.C. is called the golden age of philosop ...

  • History Of Electoral College - 951 words
    History Of Electoral College HISTORY OF THE ELECTORAL COLLEGE The Electoral College is the name for the electors who nominally choose the president and vice president of the United States. Each of the states receives a certain number of electors, which is determined by the total number of senators and representatives it sends to the U.S. Congress. Therefore, each state has at least 3 electors. The Electoral College was devised by the Framers of the Constitution as a procedure to elect the president by the people, at least indirectly. The framers came up with this procedure for many reasons. Such reasons included the lack of information to make a good choice by the people and it was also a wa ...

  • History Of Physics - 1,315 words
    History Of Physics Physics began when man first started to study his surroundings. Early applications of physics include the invention of the wheel and of primitive weapons. The people who built Stone Henge had knowledge of physical mechanics in order to move the rocks and place them on top of each other. It was not until during the period of Greek culture that the first systematic treatment of physics started with the use of mechanics. Thales is often said to have been the first scientist, and the first Greek philosopher. He was an astronomer, merchant and mathematician, and after visiting Egypt he is said to have originated the science of deductive geometry. He also discovered theorems of ...

However, the standard did not mention about what should be done with the credit that arises as a result of charging the cumulative dividend to the P & L account as an appropriation when the company has no distributable profits. For instance, it could be credited to liabilities as a dividend payable, but this does not answer - the dividend cannot be declared without distributable reserves from which to make the payment. In addition, there are no transitional provisions in the standard and, therefore, it appears ...

    Joseph John Thomson was born on December 18, 1856 near Manchester, England. His father died when J.J.. was only sixteen. The young Thomson attended Owens College in Manchester, where his professor of mathematics encouraged him to apply for a scholarship at Trinity College, one of the most prestigious of the colleges at Cambridge University. Thomson won the scholarship, and in 1880 finished second in his class in the grueling graduation examination in mathematics. Trinity gave him a fellowship and he stayed on there, trying to craft mathematical models that would reveal the nature of atoms and electromagnetic forces. One hundred years ago, amidst glowing glass tubes and the hum of electricity ...

After a few descriptions of the actual torture which individual Jews suffered, he points out that "nothing is working, send in the nuns." The nuns perform a synchronized swimming routine in which Jews are sent down a chute into a pool to be dragged under by nuns. At the end of the scene, seven nuns are standing on a menorah with sparklers on their heads, while the chorus, led by Torquemada, sings, "Come on you Moslems and you Jews. We've got big news for all of youse. You'd better change your points of views today. Cause the Inquisition's here, and it's here to stay." When Bro ...

  • Mobilizing Men: Analysis Of The Mens Movement In Canada - 1,276 words
    ... divorce courts and blood sucking ex-wives. However, what has seen the largest reaction and the biggest affect on the development of men's groups in Canada, has been the issue of violence against women. Since 1989, we have seen emergence of two significant large men's organizations, including Men For Change (Halifax) and the development of the White Ribbon Campaign(WRC), (Toronto). The uniqueness of this phenomena is as a result of not only the different sociological and cultural norms between Canadian and American men, but more significantly the Montreal Massacre. On December 6 1989, a young man entered the Ecole Polytechnic in Montreal with a Sturm Ruger Mini-14 semi-automatic rifle an ...
