Gold is a precious metal which has been used for years and when we think of gold we think of shining bars in a bank vault, coins or beautiful jewellery. When we think of gold it’s usually a shining yellow gold however can come in many colours. The colour of gold can range from red through the visible spectrum to purple and violet.…
Gold is something that you actually have to put effort into, in order to get it from the earth. It's not free to harvest, it takes time, energy, and money. For this reason, it always retains its value in times of economic trouble. Some even believe that the United States should go to a completely gold standard, getting rid of the Federal Reserve and getting away from printed money. This would restrict the government to only spend the money that they actually have in their possession, so debt and inflation would be controlled and we would not have economic collapses like we see today. Recessions are still possible on a gold standard, but they would not be nearly as severe. In fact, most people don't know that in the last recession, we were threatened by a Great Depression but by bailing out the banks and the car industries, we avoided that but only temporarily. One day, the recession will return and if you have invested in buying gold coins, you will have money by your side to support…
Dental (silver) amalgam has been used in various dental applications for more than a century. In fact, the first written record of amalgam being used in dental applications is 1528 .Yet, it is still a very commonly used material today. Amalgam was first made by melting down Spanish or Mexican coins and mixing them with mercury . When it cooled and settled into the cavity, it actually turned black. Bell then evolved this rudimentary procedure into a more controlled alloy in 1819. The substance created a massive wealth for the dental surgeons who promoted its use. However, the substance was actually overused, and in 1845 a convention of dental surgeons agreed to stop its use altogether. They believe that the substance was ineffective, but in actuality it was just overused in situations that it was not designed for. In 1850 it was realized that the substance was irreplaceable and was allowed back…
This material is comprised of the chemical Aurum, known to be a dense, soft and ductile metal. This material alone serves little purpose other than the perceived value added by societies around the world. Being one of the materials most commonly used for trade, gold was introduced to the United States during 1793 gold was discovered in North Carolina. This discovery went with little attention for the public with gold still being an unknown material. Gold was later discovered at The Reed Farm in North Carolina 6 years later in 1799. This new discovery created public attention and a new sense of demand for the…
Gold was a major factor in bringing the Europeans to the New World. Gold equals money and money equals power, this is the philosophy of most kings to explore the New World. They wanted power and it did not matter how they got that power as long as they got it. In the case of Hernan Cortes, he killed of the Aztec leader, Montezuma, to gain the Aztec’s gold. After the fall of the civilized empires in the New World, the Spanish set up civilized empires which prospered in gold. The Spanish received gold and in turn they also received power. Power motivated most of the countries; Spain, France, England, Portugal, and the Netherlands, to explore and gain the profits. Although gold was not the only reason they explored as much as it was trying to find a new route to India and the Orient. That was the original plan. Once they hit land and discovered it was not India and the Orient, they explored and came across gold and many other riches. Once they were brought back the kings would charter ships and try to gain as much gold, money/power, as they could. After the fall of the Catholic Church and the rise of the monarchies, all of the kings were searching for new ways to show they were more powerful, gold helped with that. Gold was not only a surprising find in the New World, but also a key into the search for power by the kings of the respective countries that explored.…
In this experiment that we performed, there were many methods that were used to help us manipulate and identify the bacteria E.coli on a MacConkey agar plate. The first part of the experiment involved the methods of manipulating, identifying and counting the bacteria and the second part was to find out whether the bacteria E.coli was the only type found in the given area by gram staining.…
Jay Gatsby is like the American government – the weak, dishonest, inefficient government we believe to be the best in the world. His individual qualities are ones that, when examined objectively, should be frowned upon. Like the government, we can hate these qualities but love the whole. From the beginning of The Great Gatsby, he is protected by the most influential character; the narrator. Because our first impression of Gatsby is provided by a biased friend of his, our view is skewed in his favor, resulting in overcompensation for his obvious flaws. Gatsby is not a good man, we just want him to be. We so strongly want to believe that he is great and pure that we are willing to look past his inherent qualities, to construct in our minds a…
The majority of today’s patients will choose white fillings over silver. The reason for that is the mercury in the amalgam is often viewed as potentially toxic and cause sensitivity. Depending on which tissue it settles in, it will differ from one person to another. The suggested answer is that mercury from fillings doesn 't cause a specific disease. It causes poisoning, and a very small number of people are allergic to metals in the amalgam and may need to have another type of treatment.…
Death is a word commonly associated with the life of Edgar Allan Poe. In Poe’s life it seemed as if anyone he grew close to died, especially women. Poe’s mother Elizabeth Atkins died from tuberculosis, and a couple of years before her death, his father David Poe abandoned the family (Mystery). Poe had lost both of his parents by the age of three and was taken in by John and Frances Allan. Through Poe’s teen years he quarreled with John but grew to love Frances like a mother. Sadly his beloved foster mother passed away when he was just out of college and in the military. After she died he was soon discharged from the army and went to live with his aunt, Maria Clemm, and cousin Virginia. Poe fell in love with Virginia and they soon married (Hutchins). Through this marriage Maria Clemm became his mother figure, “Although there is some debate…
Cinnabar (HgS, the natural compound mercury can be largely found in) was found in caves of France in Spain about 30,000 years ago as paint (Vermilion) from Paleolithic painters due to its bright red pigment. Mercury colored the world of the primal people and it didn't stop there. Many people believed mercury contained miraculous traits like immortality or forming gold. An emperor of China, Qin Shi Huang Di believed that ingesting mercury pills would bless him eternal life. While mercury appears benign it can be quite fatal once in enters the human body. The emperor took these pills, a mixture of mercury and jade, and sought eternal death rather than life. China, however, was not the only civilization to believe (that) mercury had healing properties. The Greeks, Romans, and Egyptians all used mercury in cosmetics and ointments due to its pretty front. Romans, on the other hand, found other uses for mercury in mining fields. Mercury can form amalgams with almost every metal and gold was not the exception. The process of mining the amalgams and distilling out the mercury(since it could easily achieve liquid state) left people with gold or with other desired metals. This innovation sparked riches and curiousity in people but it also carried many health risks. The Romans employed slaves into the mine shafts and many died due to mercury poisoning the lungs or seeping into the skin. Despite these side effects it did not deter the early scientist, or known as the 'alchemists'. Many alchemists believed that adjusting the proportion of sulfur in mercury compounds would produce different metals(in which many hoped to achieve to create gold.). Of course, early alchemists could not achieve their whimsical goals due to their lack of understanding of how elements…
Something I consider ‘’gold’’ is my grandpa, because he was always there for me and when I was down he gave me a big hug and helped me through the rough times I had. I lost my grandpa because of an Illness he had, he had a bad illness where he was in the hospital for most of the time and that made me very sad. I tried to hold onto him by spending a lot of time with him and taking care of him, because he liked it when I was there spending time with him. I was unsuccessful because my grandpa passed away, but I think of him everyday and in my heart I know he is here with us even through the rough times. In the poem ‘’Nothing Gold Can Stay’’ by Robert Frost, he states, “ Her hardest hue to hold “ which means you can't hold on to someone or something…

PLATINUM Platinum is a grayish white metallic element that is soft, dense, very ductile and malleable with a high tensile strength. It has been used in jewelry, dentistry, Xray equipment, medical and surgical instruments and heating units. Due to its relative inactivity, platinum both as a free metal and alloyed with rhodium, is an almost indispensable material for such devices as magneto contacts, spark plug electrodes, radar parts, bomb sights, and computing devices. In the chemical industries, platinum and its alloys are also essential as catalysts and for other uses. Platinum is much more expensive than gold because of its rarity and extensive usage. Platinum is different from white gold because the latter is gold mixed with nickel, zinc and copper. Upon application of nitrate acid, platinum remains white while white gold turns yellow.…
