Uranium

million years old. Dating methods are used to find out about how old an artifact may be, or how old it is exactly. Relative dating methods are stratigraphy and style analysis. Absolute dating methods used are absolute dating, radiocarbon dating, uranium-lead dating, and luminescence dating. Stratigraphy as a dating method, is based around the principle that older artifacts are usually found below younger artifacts. When archaeological sites are excavated, the layers of ground near the…

In the poem, “Halloween in the Anthropocene, 2015” by Craig Santos Perez, theme is developed through uses of cynical imagery, critical personification, and gloomy symbols. The main idea is that we have all caused problems on the Earth, as Craig indirectly states, all from our own greed. Many examples were provided that help support this idea. Although Halloween is generally a pretty- well it’s supposed to be scary, but while most kids find the fun in it, other children all around the world are…

way that cosmic waves react, was the head scientist of the Chicago campus study team (Groves xvi). He stated that the purpose of the research was to build understanding required to design and construct and operate a plant for the transformation of uranium to plutonium. Once Roosevelt came to the conclusion that this weapon had to be created before Hitler’s forces beat him to it, he was the one that gave the project much needed funding and support to continue. Luckily, FDR did not have to use it…

At the time living in fear of Germany possibly taking his idea and put it to us, he decided that it was best to patent this theory so Germany couldn’t get their hands on it. In December 1938 German scientists split the uranium atom they had also theorized a similar idea or if not the same. By now Szilard believed the race was on for the atomic bomb. He had moved to the United States, and he felt the U.S. must build the a-bomb before the Nazis made their own atomic bomb…

research for creating an atomic bomb. In the article, The first atomic bomb test is successfully exploded, it says, “But early in 1942, with the United States now at war with the Axis powers, and fear mounting that Germany was working on its own uranium bomb, the War Department took a more active interest, and limits on resources for the project were removed.”3 This meant the War Department put aside the Manhattan Project and prioritized destroying the hydroelectric plant. At the end of World…

During WW2, the US annually mined over 17,000 tons of uranium oxide in the Rocky and Sierra Nevada mountains. Before 1959, no laws dictated where to properly dump chemical waste. Ergo this waste would routinely be released into waterways. By 1980, there were about 35 large scale mills throughout the US producing uranium oxide. The environmental impact and worker health hazards of the uranium mining industry have been the subject of several lawsuits. Most notable was a spill…

Power of Nuclear Energy What if the world was powered by nuclear power cleaner than coal and cheaper than most power? This question was never really been asked because people are to scared. When they hear nuclear energy they think of all the bad thing nuclear energy has instead of the good thing about it. Like how nuclear energy has no greenhouse gases or smog. This are good points on how nuclear energy is good, but people only remember the bad thing. Since nuclear energy is clean, inexpensive…

The bomb used Uranium-235, something which had been discovered previously by the Nazi’s. Members of the research team worked countless hours on finding a way to split its nucleus and set off a chain reaction. Oppenheimer found that by shooting neutrons at the nucleus of a Uranium atom, the energy would grow to the point where it could explode (Andrew Radar Studios). This process was highly expensive…

During World War II, America was involved in a bombing campaign with Japan. This was because of the bombing of Pearl Harbor. Pearl Harbor was a United States naval base near Honolulu, Hawaii. The bombing of Pearl Harbor took place on December 7th, 1941. This destroyed 20 American naval vessels, 8 battleships, killed more than 2,500 people, and wounded many others. The United States wanted to avenge Japan, so they used precision bombing. Precision bombing was not successful, and “fire-bombing”…

created as a smoke signal by Ralph using Piggy’s specs represents uranium and nuclear power or weaponry. The fire just like uranium was originally used for good; as a smoke signal, yet later on it was stolen and used to roast the pig Jack’s group killed so the fire tore them apart. "The fire is the most important thing on the island. How can we ever be rescued except by luck, if we don’t keep a fire going?” Pg. 113-114 Paragraph 8. Uranium was used for medical research and power but was used for…
