The definition of radiation is the emission of energy electromagnetic waves or as moving subatomic particles, especially high-energy particles that cause ionization. One of the scientist who discovered radiation was Henri Becquerel, the way the French scientist discovered radioactivity was when we was conducting an experiment with uranium-bearing crystals to sun light, then put it on a photographic plate, he then had set off his experiment for a few days because it was very cloudy and the sun wasn’t shining so Henri put the sample uranium and the plate the same sealed drawer. When he went to get the uranium and photographic plate, Becquerel then discovered that the crystals left a clear image on the photographic plate, Henri wondered how that could happen because there was no energy to produce the image but Henri then discovered that a piece of mineral which contained uranium could produce its image on a photographic plate without light, Henri realized that it was radioactivity. Ernest Rutherford among his many accomplishments one of them were the way he took part in radioactivity by...
“Art can use the power of visual image to challenge and even change popular opinions about important and universal issues. Art can be a very influential way to give a strong, direct comments and criticisms on things that have happened in society and culture.” (Rehab-Mol J, 1998, p6) Indigenous art is mostly about connecting to their land and their religious belief; however, art has different forms, especially the Indigenous contemporary art as it uses ‘modern materials in a mixed cultural context’.

James Wright was a poet that dealt with many hardships in his life, but he found a way to turn those negative moments into beautiful works of poetry. As a child, he lived in poverty with his family and later on suffered with depression and alcoholism. Growing up in Ohio, Wright learned how to work hard which is reflected in his poetic achievements. Wright turned his struggles into poems and for him to be able to achieve success through his pain is what makes his work American. Frank McShane wrote “The Search for Light” in Peter Stit and Frank Graziano’s James Wright: A Profile, and in the book McShane includes: “James Wright knew how restricted most American lives were” (131). For Wright to be able to live the “restricted” life McShane is discussing,
Absence of Light and Life in Ethan Frome Ethan Frome, by Edith Wharton, is set in Starkfield, a small community plagued by harsh winters that seem to ebb away at life. In this town lives Ethan Frome, a crippled man who seems to be the physical embodiment of mortal suffering. A new arrival to the town, drawn by Ethan. He is compelled to uncover the story behind the enigmatic man. What he discovers is a tragic tale of human suffering, an excellent example of tragic irony.
In papal Rome in the early 16th century the “Good Book” was the reference book for all scientists. If a theory was supported in its holy pages, or at the very least not contradicted, then the idea had a chance of find acceptance outside the laboratory. Likewise, no theory no matter how well documented could be viewed with anything but disdain if it contradicted with the written word of, or the Church’s official interpretation of scripture. For these reasons the Church suppressed helio-centric thinking to the point of making it a hiss and a byword. However, this did not keep brave men from exploring scientific reason outside the canonical doctrine of the papal throne, sometimes at the risk of losing their own lives. While the Vatican was able to control the universities and even most of the professors, it could not control the mind of one man known to the modern world as Galileo Galilei. Despite a wide array of enemies, Galileo embarked on a quest, it seems almost from the beginning of his academic career, to defend the Copernican idea of a helio-centric universe by challenging the authority of the church in matters of science. Galileo‘s willingness to stand up for what he held to be right in the face of opposition from Bible-driven science advocates set him apart as one of the key players in the movement to separate Church authority from scientific discovery, and consequently paved the way for future scientific achievement.
In All The Light We Cannot See by Anthony Doer, a German boy with the love for technology named Werner lies about his age and gets drafted into the Nazi army. He is sent to a place called Sculpforta for him to train to be in combat in the army. There he meets a nice boy with the name of Frederick. Fredrick is the son of wealthy parents, with a lean body and bad eyesight, he barely makes it to Sculpforta. There he meets our main character, the German boy, Werner. Frederick plays a big role in the book when it comes to character development. Not only modes he grow as a person with his experiences, but he also makes Werner grow as a person.
François Dominique Toussaint L'Ouverture was an educated former slave and soldier of the king that would eventually lead the revolution against French rule in Saint-Domingue. The prime objective of Toussaint’s letter to the Directory of France was to end colonial tyranny and declared an end to slavery in Saint-Domingue (Haiti) by utilizing the language of freedom and equality in reminisce of the French revolution. Toussaint fiercely pursued the abolition of slavery, as his letter warned the Directory of France against the reinstatement of slavery. Although Toussaint was captured in 1802 and executed in 1803 by the orders of Napoleon Bonaparte, his movement lived on. The French ultimately failed to recapture the island of Saint-Domingue, declaring the independent state of Haiti in 1804.
Radiation is something that the naked eye cannot see, yet has the potential to save lives one treatment at a time or even one image at a time. Since the discovery of x-rays in 1895, it has branched out into numerous modalities each independently specializing in their own ways. X rays are used to aid in the diagnosis and treatments of patients on a case by case scenario. Sometimes doctors can make a diagnosis on the same day or conclude that a patient will require radiation therapy within weeks to follow. Whatever it may be, the importance of x rays and radiation itself is a crucial part of the medical field when it comes to saving lives. Initially it all started with the discovery of x rays but then three years later radiation therapy was introduced to aid with
Radiation has always been in everyday life even before Roentgen discovered x-ray. The mountains give off natural radiation, other forms of radiation are coal burning power plants, x-rays from a TV, and an airplane ride. The average dose from background radiation is about 360 mrem every year. There are two types of radiation, nonionizing and ionizing radiation. Examples of nonionizing radiation are microwaves and radio waves broadcasting. Ionizing radiation refers to gamma and x-rays. Ionizing radiation means that the rays are able to remove an electron from the atom then ions can be formed. The ions can cause damage when reacting with other atoms. Cells are able to be repaired if low dose are received. However, if cells get a high dose, the cells will be damaged or possibly die. If the cell is damaged permanently then it is referred to as a mutated cell.
In All the Light We Cannot See, Anthony Doerr incorporates thoughtful ideas and concepts to create an emotionally gripping story of a German orphan and blind French girl in World War 2. Throughout the novel Doerr focuses on the themes of the choices people make in adversity, the possession of power and the blindness and awareness within people, which are developed through juxtaposing ideas, the utilization of vivid imagery and the characterisation of the two main protagonists.
What is Radiation? Radiation is a A form of energy carried by waves or a stream of particles. Radiation is a fragment that is capable of ionizing atoms or molecules isolating electrons from them due to its sufficiently possessed energy when it is passed through them. Radiations include alpha, beta and gamma rays. They can cause severe damage when absorbed by living tissue, and are therefore a health hazard they can effect the repairing ability of living cells. Ionizing radiation consists of subatomic particles or electromagnetic waves that are energetic enough to detach
Philippe Petit changed numerous peoples’ thoughts about the Twin Towers when he performed his high wire walk between them in 1974. Before Philippe Petit walked the high wire between the Twin Towers in 1974, people weren’t certain how they felt about the construction of the World Trade Center. After Philippe performed, people began to warm up to the idea of the towers. Philippe Petit walked the high wire between the Twin Towers on August 7, 1974. This event prompted Andrew McMahon to write the song “Platform Fire” about this event for his band, Jack’s Mannequin. This song was not a hit for the band; however, fans of Jack’s Mannequin seem to have a special place in their heart for it.
From the day Pierre met Marie at a friend’s house, he was smitten. Together the scientific couple published over thirty papers on radioactivity. They could have become rich by patenting their process of extracting radium, but the Curies refused to do so. They were generous. They thought that scientific research should not be hidden but belong to everyone (Bailey). The Curie’s work, which dealt with changes in the atomic nucleus, led toward the modern understanding of the atom as an entity that can be split to release enormous energy (“Marie and Pierre Curie”).
Uranium, a radioactive element, was first mined in the western United States in 1871 by Dr. Richard Pierce, who shipped 200 pounds of pitchblende to London from the Central City Mining District. This element is sorta boring but I found something interesting, they used it to make an an atomic bomb in the Cold War. In 1898 Pierre and Marie Curie and G. Bemont isolated the "miracle element" radium from pitchblende. That same year, uranium, vanadium and radium were found to exist in carnotite, a mineral containing colorful red and yellow ores that had been used as body paint by early Navajo and Ute Indians on the Colorado Plateau. The discovery triggered a small prospecting boom in southeastern Utah, and radium mines in Grand and San Juan counties became a major source of ore for the Curies. It was not the Curies but a British team working in Canada which was the first to understand that the presence of polonium and radium in pitchblende was not due to simple geological and mineral reasons, but that these elements were directly linked to uranium by a process of natural radioactive transmutation. The theory of radioactive transformation of elements was brilliantly enlarge in1901 by the New Zealand physicist Ernest Rutherford and the English chemist Frederick Soddy at McGill University in Montreal. At dusk on the evening of November 8, 1895, Wilhelm Rontgen, professor of physics at the University of Wurzburg in Germany, noticed a cathode tube that a sheet of paper come distance away. He put his hand between the tube and the paper, he saw the image of the bones in his hand on the paper.
The impact of nuclear power on the modern world has improved Various sectors of the economy and society .i.e. Food and Agriculture, Insect control, Food Preservation, Water Resources, Military, Medicine, Research and Industry. “In 1911 George de Hevesy conducted the first application of a radioisotope. At the time de Hevesy was a young Hungarian student working in Manchester with naturally radioactive materials. Not having much money he lived in modest accommodation and took his meals with his landlady. He began to suspect that some of the meals that appeared regularly might be made from leftovers from the preceding days or even weeks, but he could never be sure. To try and confirm his suspicions de Hevesy put a small amount of radioactive material into the remains of a meal. Several days later when the same dish was served again he used a simple radiation detection instrument - a gold leaf electroscope - to check if the food was radioactive. It was, and de Hevesy's suspicions were confirmed.
Radiate, by definition, means to send or spread out, and this is important to know when thinking about how exactly radiation occurs. We already discussed a child coming in from playing out in the snow, snuggling up to their father and getting warm through heat transfer by conduction- physical contact. Now, let’s say that the child comes inside from out in the cold, takes off their snow gear and places their hands over a hot fire instead. The child’s hands will warm up through the transfer of heat energy through radiation. Another example, which can be seen every day that you walk outside and the sun is shining bright- is the heat received on Earth by the sun, through the means of radiation. The Earth receives heat through the electromagnetic waves, and our bodies feel the warmth of the sun from these waves that are absorbed within our skin. Radiation is the only means by which heat energy can transfer through the empty space between Earth and the sun- neither conduction or convection have the ability to play a role in this area and therefore, we can see how truly important radiation is. Another interesting fact in regards to radiation is that “because more heat is radiated at higher temperatures, a temperature change is accompanied by a color change. For example, an electrical element on a stove glows from red to orange, while the
