James Chadwick Research Paper

One of J.J. Thomson's most significant contributions to science, and thus to the study of atomic theory, was his discovery of the electron. Before the discovery of the electron, the atom was already associated with having electric charges-both positive and negative-but the idea of an electron existing as its own particle was unheard of. It was in 1897 when Thomson first conducted the beginning of his now famous experiment, in which he used a cathode ray tube to aid in his findings. A cathode ray tube, is a vacuum tube in which cathode rays, negatively charged particles, are produced at the cathode and travel through the vacuum, which is created when gas is extracted from the tube. J.J. Thomson discovered that in order to determine

A good friend to George Washington, Nathanael Greene was an important general in the American Revolution that helped the American forces defeat the British. Although his battles didn't always end up in a victories had many victories which made it so we could live in a free country today.

Hue Jackson is not at all surprised with the way Deshaun Watson is playing as a rookie.

William Johnson was born a slave in the year 1809 but was freed by his owner, probably his father in 1820. His owner had earlier released William’s sister and mother. William Johnson upon being freed became a barber apprentice in Natchez town. William’s brother-in-law had a barbershop which he took over in 1830 and later on got married to Amy Battles. They had eleven children. Amy was a free person and just like William was black (National Humanities Center Resource Toolbox, 2007). William Johnson went on to operate several barbershops, owned land, and rented buildings. He also had a bathhouse and regularly loaned white and black people money which was paid at an interest. Like other free blacks in the South, William Johnson owned slaves and at times sold them too. The diary is a record of his daily personal endeavors, majorly about the payment of his debts, the items he bought and the running of his family. William was murdered by a free black man, Baylor Winn, with whom they had a boundary conflict. Despite his murderer being identified, he escaped prosecution since according to his evidence, he was a white man, and so no black man could testify against him (Humanities Center Resource Toolbox, 2007).

John Simpson Kirkpatrick ‘the man with the donkey’ has had an incredible involvement with Australia in the World War One. His life leading up and during the war made contemporary Australia commemorate Simpson because of his sacrifice and the significance of his involvement during the war and his true Australian spirit.

According to DePra’s poem, “The electron is minus, the proton is plus,/ the neutron is neither” (Doc. 2). In other words, a neutron is neutral, the electron is negative and the proton is positive. After these discoveries, more inventions were made to help further our understanding of atoms, for instance, the the electron microscope. Electrons were discovered before Rutherford by JJ Thomas (OI). Thomas was using a cathode ray and discovered that atoms are made of smaller subatomic particles

Twenty-one years ago this month, on September 6, 1992, the decomposed body of Christopher McCandless was discovered by moose hunters just outside the northern boundary of Denali National Park. He had died inside a rusting bus that served as a makeshift shelter for trappers, dog mushers, and other backcountry visitors. Taped to the door was a note scrawled on a page torn from a novel by Nikolai

What is an athlete? An athlete is someone who strives for first place and works hard to get there. There has been many controversies over whether or not NASCAR drivers are considered athletes or not. However, NASCAR drivers are considered athletes. Take five time championship winner Jimmy Johnson for example. Jimmy Johnson is an athlete because he practices as often as he can and he participates in a highly competitive and challenging sport.

Oliver Johnson an 18 year old, African-American boy, who grew up in the streets of Pompano Beach, Fl. Never knowing his father he relied on the streets, gangsters, and hustlers to learn how to be a man. At the age of nine Oliver was selling drugs. His mother was a drug addict who preyed on the love that Oliver had for her to score her free drugs. Oliver became a man before he would ever knew the joys of being a child. Oliver paid bills, brought groceries, cooked food, went to school and kept a perfect attendance. Even though Oliver was deep in the game of drug dealing, and had a crazy home life; he was a very smart student and very respectful to everyone who crossed his path. There were always some older men in the neighborhood who knew

What is the atomic structure you may ask? Well, it’s the law stating the structure of an atom. It is composed of a positively charged nucleus containing a certain amount of protons (positive), neutrons (neutral charge), and electrons (negative). The amount of each subatomic particle (proton, neutron, and electron) all depend on what the element is. Now although this statement may seem fairly simple it was most definitely not. People have been studying the atomic structure for more than 300+ years and are still studying it. So after reading this you may wonder who even made this atomic structure up. After hundreds of years of research there is not any one individual who made the structure up but roughly

Edwin Chadwick was an early British reformer that believed the best way to approach social reform was to use a utilitarian method. This means that public problems should be dealt with on a rational and scientific basis and according to the principal “the greatest good for the greatest number”. He believed that disease and death caused poverty and that disease could be prevented by cleaning up the urban environment. In my view and what I believe to be the views of all urban planners, Chadwick is a hero. The use of sewer systems to remove waste and minimize diseases has reduced epidemics that rapidly spread through factory cities. There are 3 things that he did that are important and relevant today. The first would be his gathering of local

Ernest Rutherford was a New Zealand born British physicist who is famously known for “splitting the atom.” His work on the gold foil experiment contributed greatly to the model of the atom and helped develop the standard model of the atom to what we now use today. Without his contributions we would still be using the Plum Pudding model, an out dated and incorrect model, and we would have less of an understanding of how atoms form the world around us.

John Dalton, a British chemist and physicist, that was born on the 6th of September 1766. His study of gases led Dalton to wonder about what these invisible substances

Nuclear knowledge has existed for a long time. Nuclear Engineering U.S. Department of Energy relates, ―By 1900, the physicists knew the atom contains large quantities of energy‖ (par 11). Many others formed good theories, such as Ernest Rutherford and Einstein’s contribution with his equation E=mc^2. In 1934
