Mercury Mariner

silver fillings. Dental amalgam is a mixture of mercury, silver, tin and copper. Mercury, which makes up about 50 percent of the compound, is used to bind the metals together and to provide a strong, hard, durable filling. After years of research, mercury has been found to be the only element that will bind these metals together in such a way that can be easily manipulated into a tooth cavity. Is mercury in dental amalgam safe? The amount of mercury released in the mouth under the pressure of chewing

Element 80, or mercury, is an element with quite an interesting and extensive history. I chose this particular element because of this. I have a basic knowledge of mercury already, but I would love to learn all that I can about it. I enjoy history and I take advantage of every opportunity I can to learn more about it and from it. I am interested in this element because of the name it was given, the uses we have and have had in the past for it, and the fact that the atomic number is 80, which includes

Some parental concerns persist that vaccines may cause Autism. Multiple hypotheses have been proposed throughout the years. There is a major worldwide increasing rate of Autism diagnoses. Theories have centered on measles-mumps-rubella vaccine, thimerosal, and the large number of vaccines being administered. Studies have showed that there is no link between receiving vaccines and developing Autism Spectrum Disorder. An Institute of Medicine in 2001 did a report on eight different vaccines given

“Characters Change” “All Summer in a Day” by Ray Bradbury is a science fiction short story about how Venus only has one hour of daylight and the rest of the time it is cold and raining all year and only in seven years they will have that one hour of daylight. There are people living on Venus and there is one little girl in middle school who adores the sun light and it is her only way of happiness unlike all of the other kids at her school who don't really mind the rain and have never seen the daylight

Misophonia Was Its NameIt felt like my ears were being clawed at by sharp nails, and as if it could not get any worse, it seemed as if the wounds that remained had poisons rubbed into them to even further set me into a state of agony. Everyday I was alive I couldn't help but bawl and beg for some sort of mercy, to make the pain stop, but because no one understood why I was in such pain, they did not know how to stop hurting me. The strangest thing of all though, was that even I did not know why I

Johannes Kepler was a German astronomer. He was known for discovering the three most important laws of planetary motion. He was also partially known for helping prove that the sun was actually the center of the universe, not the Earth. Johannes Kepler was born on the 27th of December in 1571. When he was young he got sick very easily. His hands didn’t work very well and his eyesight was damaged due to smallpox. Katharina Guldenmann, his mother, was an herbalist and loved the outdoors. She tried

The element Mercury is a group 12, period 6 transition metal. Its atomic number is 80 and its atomic mass is 200.59. Mercury has a silvery, mirror-like appearance and is very dense. It weighs 13.6 times as much as the same volume of water (Blaszczak-Boxe, 2014). Mercury is the only common metal that remains a liquid at room temperature. Mercury is a monoatomic substance and is represented by the symbol Hg on the periodic table that comes from the Greek word hydrargyrum, which means “liquid silver”

When we have summer vacation, it doesn’t seem to last long enough, so imagine only seeing the sun once every seven years! I was able to imagine this due to a certain author; Ray Bradbury. Bradbury is an accomplished writer who is well known for writing short stories. In “All Summer in a Day”, Bradbury describes life on Venus. A main theme of the short story “All Summer in a Day” is that being different is considered a negative thing and is disliked. The theme that being different, is seen as a

When it comes to understanding how the planetary solar system works, few natural philosophers have affected us more than Nicolaus Copernicus. Nicolaus Copernicus was a scientist who was born on February 19, 1473. Around 1508, Copernicus started to develop his own idea of the solar system. His theory stated that the Sun was the center of the universe. Before Copernicus, it was widely believed that the Earth was the center of the universe rather than the Sun. Copernicus’s theory stressed the idea of
