Ernest Rutherford
Ernest Rutherford was born in Spring Grove in New Zealand on August 30th, 1871. His parents, James and Martha, had emigrated from Great Britain and believed their children, numbering 12, should have proper education. At the age of 16 Ernest won his first scholarship to Nelson College, where he was a popular student. He followed with a second scholarship to Canterbury College in Christchurch, and by 1893 had graduated with first class honours in Physics and Mathematics. Rutherford stayed at Canterbury for a further year to study Physics in more detail, particularly how iron reacted in magnetic fields. He also researched electromagnetic (wireless) waves, shortly after they were discovered by the German Heinrich Hertz, and produced two papers on his findings, winning another scholarship in England.
When he arrived in Cambridge in 1895, Ernest worked for J.J. Thomson, a lecturer at Cambridge’s ‘Cavendish Laboratory’. He often wrote letters to his girlfriend, Mary Nelson, and his mother, and in these he depicts how some members of Cavendish were jealous of him, or so he thought. Everywhere Ernest went, he was recognized as being a leader and thinker, with ‘amazing concentration’.
He continued working on wireless or Hertzian waves, and discovered they not only traveled through brick walls but over a distance of two miles. When Rutherford gave an experimental lecture for the Physics Society of Cambridge University, his paper was so successful that it was also published in the “Philosophical Transactions of the Royal Society of London, a signal honour for so young an investigator.”*
Late in 1895, after Rontgen had discovered x-rays, Thomson invited Ernest to join him in looking at how these x-rays passed through a gas. The discovery made was that x-rays made many ions, or electrically charged particles. These particles had either a positive or negative charge, and were therefore attracted to each other in the same fashion as the north and south poles of a magnet. When they joined together the charges evened out, and the particles had no charge.
Rutherford began working on his own and discovered a formula for calculating the velocity and rate of joining of these particles. He produced more papers on this, which are still relevant to modern physics.
When it was found that rays given off by uranium could fog a photographic plate, Ernest looked at the process and decided it was similar to X rays but that uranium rays had two different types, alpha and beta rays, which when combined, ionized and penetrated air exceedingly well.
After being educated at Trinity College Dublin he moved to Queens University in Dublin where he worked as the Secretary of the Administrative Headquarters of the Queens Colleges. It was then when he produced his most important conceptions and calculations. His particular theory was that electrical charges in atoms are comprised of negatives which he would call electrons. He calculated the magnitude of a particle of electricity, or Stoney Unit which he would later name the electron in one of his papers in the Transactions of the Royal Dublin Society in 1891. The path taken to get to Stoney Units utilized the Stoney Scale which was the mathematical equation he developed to get his desired answer when

Vincent Van Gogh is celebrated today as the greatest Dutch painter, besides Rembrandt (“Vincent Willem”). Born in Holland on March 30, 1853, Van Gogh had five other siblings and two parents, and although his mother was an artist, he never bothered with art until much later in his life (“Vincent Willem”). Van Gogh had many shortcomings in his little and dismal time on earth and it was not until his late twenties, after all else had failed, that he gave art a chance. Thanks to the help of his older brother Theo, Van Gogh was able to put all of his emotions and mental worries into productive use, creating masterpieces that are sold today for millions of dollars (“Vincent Willem”). Although he is hugely successful today, Van Gogh had little to no fame in his lifetime and he struggled immensely with his mental state of mind for many years. Ultimately his mental illness (some believe there were more than one) lead to his untimely death, but his turbulent state of mind also helped him to create magnificent images that are revered as some of the greatest pieces of art of today.
Van Gogh was born on March 30, 1853, in the rectory of Zundert in Barbant (Burra). His father was a soft-spoken Dutch clergyman. The only thing Van Gogh got from his father, was the desire to be involved in the family church. Even at an early age, Vincent showed artistic talent but neither he nor his parents imagined that painting would take him where it did later in life. One of his first jobs came at the age of sixteen, as an art dealer’s assistant. He went to work for Goupil and Company, an art gallery where an uncle had been working for some time. Three of his father’s brothers were art dealers, and he was christened after the most distinguished of his uncles, who was manager of the Hague branch of the famous Goupil Galleries (Meier-Graefe). His parents were poor, so his rich uncle offered to take him ...
Unfortunately, the criminal justice system is a vital piece of today’s society. Without it, the public would be free to do whatever they choose with no real consequence to negative actions. According to the Bureau of Labor Statistics, roughly 3 million workers were employed in the criminal justice field in 2015 (Occupational Employment, 2016). This is made up of countless different agencies, including law enforcement, corrections, homeland security, and many more. Corrections is a key element in the criminal justice system, which has its own unique functional philosophy, administrative structure and functions, theoretical assumptions that govern its existence, organizational mission, goals and objectives, and division of responsibilities.
To begin, Offred defies convention in many ways. The requirement of a Handmaid is to wear a loose, red dress that covers the woman’s entire body except her eyes. The Handmaids are not permitted to wear makeup and they are required to keep their faces covered. The Republic has these requirements in order to keep women from feeling vain. Vanity is seen as a sin in Gilead, and women are not supposed to be
The professionalism that needs to remain in the correction facility is always remember to remain calm any situation that might occur between the inmate and staff. Professionalism is part of the correctional officer's job to make sure that they’re fit for the position and making sure that the officers do not set themselves up for failure you have to make sure that you’re perfect for the position. Correctional officers are taught the importance of boundaries with the inmates due to protection and authority. The correction officer have authority and power over the inmate when the correctional officer choose not to own up to their power or authority that’s when boundaries get crossed and problems start occur among the inmates. Discipline for the
At any given time, a single corrections officer, can expect to be outnumbered by upwards of 400 inmates (Conover, 2011). It can be chilling to work in the midst of hundreds of inmates, some of which initiate attacks and inappropriate relationships. However, other issues have impacted the psychological health and physical safety of the staff. Detrimental factors have included heavy workloads, the prisons physical structure, and a lack of support from both peers and superiors. Each workplace issue has been in addition to role problems, specifically role ambiguity and role conflict (Schaufeli & Peeters, 2011). It is believed that anyone of these undesirable facets of prison should be enough to deter the public from attempting to enter such positions, yet the essay attempts to connect the dysfunctional aspects, expanding on why these prison positions are associated with burnout and frustration. In an attempt to do the profession justice, elements that appear to have encouraged individuals to not only join, but also stay, will be explored.
Benjamin Franklin, one of the most important Americans in history, did scientific work before 1790. He had a large impact on America as well as the rest of the world. Europe played a big part of his career because the influences he felt from Europe help him develop and work in science.
All in all, the story of “A Rose for Emily” by William Faulkner represents a chilling and twisted story of a woman who used every option, even murder, to keep her state of happiness. Faulkner cleverly uses symbols, characters, and theme to fully illustrate the twisted mind of Emily Grierson and the communities never ending struggle between incorporating modern rules and keeping traditional values.
Richard P. Feynman was born in 1918 in Brooklyn; in 1942 he received his Ph.D. from Princeton. Already displaying his brilliance, Feynman played an important role in the development of the atomic bomb through his work in the Manhattan Project. In 1945 he became a physics teacher at Cornell University, and in 1950 he became a professor at the California Institute of Technology. He, along with Sin-Itero and Julian Schwinger, received the Nobel Prize in Physics in 1965 for his work in the field of quantum electrodynamics.
In “A Rose for Emily”, by William Faulkner, Emily Geierson is a woman that faces many difficulties throughout her lifetime. Emily Geierson was once a cheerful and bright lady who turned mysterious and dark through a serious of tragic events. The lost of the two men, whom she loved, left Emily devastated and in denial. Faulkner used these difficulties to define Emily’s fascinating character that is revealed throughout the short story. William Faulkner uses characterization in “A Rose for Emily”, to illustrate Miss Emily as a stubborn, overly attached, and introverted woman.

Michael Faraday is a British physicist and chemist, best known for his discoveries of electromagnetic induction and of the laws of electrolysis. He was born in 1791 to a poor family in London, Michael Faraday was extremely curious, questioning everything. He felt an urgent need to know more. At age 13, he became an errand boy for a bookbinding shop in London. He read every book that he bound, and decided that one day he would write a book of his own. He became interested in the concept of energy, specifically force. Because of his early reading and experiments with the idea of force, he was able to make important discoveries in electricity later in life. He eventually became a chemist and physicist.
In recent years, technology has become the most used and preferred way of communicating, extending across many platforms. All of these programs, such as e-mail, instant messaging, social networking websites in conjunction with text messaging and the ability to access all of these entities on the go, have come into fruition based on the immense and widely found growth made in technological advancements that have occurred in our society. With this, a massive change has developed in regards to referencing how we as humans engage in communication. We have now shifted into a society that relies heavily on the existence of digital communication, whether it be through the means of a mobile device (text messaging) or the Internet (Facebook, Twitter,
