The topic of my essay is dark matter’s importance on galaxy formation. I chose this topic because the notion of dark matter piqued my interest. It’s non-luminous so it cannot be directly observed by a telescope, which prompted me to learn more about the topic and understand it on a deeper level. Outline Introduction In this stage, the topic will be introduced, as well as a brief introduction of the subtopics that will be addressed. However the bulk of this stage will be dedicated to discussing…

Mercury: Mercury is the first planet and the closest planet to the sun. It has a very thin atmosphere. It has a temperature range of 800 degrees Fahrenheit to -280 degrees Fahrenheit. In this passage, there will be many other facts about Mercury such as the characteristics of the planet and how it compares to our planet Earth. Mercury was not discovered by one single person. Since it was discovered before history was written. It is approximately 35.98 million miles away from the sun and has…

In The Disappearing Spoon, Sam Kean explains chemistry broadly yet detailed through interesting and thrilling stories. He talks about the elements on the periodic table and how the table came into existence and why it is arranged the way it is. He also looks deeply into the history and concepts of some interesting elements. In chapter 15 called “An Element of Madness,” he goes into an explanation about selenium, manganese, palladium, barium, and unununium. Pathological science is considered…

It also has ammonia clouds. On the other hand, Mercury’s atmosphere is made of elements. These are: calcium, helium, hydrogen, magnesium, oxygen, potassium, silicon, and sodium. There is only one compound which is water vapor. These two atmospheres are alike, but different. The elements they have are in different forms, but they are still elements. As you can see…

and encourage you to do your best. In this test, the patient will seated, has a nose clip and mouthpiece in place. Firstly, the patient will instruct to exhales to residual volume (limited to 6 seconds) and then inspires the test gas mixture (10% helium, 0.3% CO, 21% oxygen, and balance nitrogen) rapidly to total lung capacity. After that the patient should try to hold the breath at total lung capacity level for a period of time approximately 10 seconds (9-11 seconds). Then the subject has to…

has increased to the size it is today. In fact it is still expanding today! Over 3-4 minutes the temperature dropped below 1 billion degrees Celsius. This meant it was cool enough for the protons and neutrons to come together to form hydrogen and helium nucleus. Finally, after 3 hundred thousand years, the…

Saturn By: Natalie James Saturn is one of the farthest planets from the sun, being the sixth. After being first spotted in 1610 by Galileo Galilei, Saturn was named after the Roman god of wealth and agriculture, Saturnus. The most common nickname for this gas giant is “The Ringed Planet”, for the large rings surrounding it that Saturn is famed for. Originally the Italian astronomer, Galileo Galilei, thought that Saturn was triple bodied, but in 1658 Dutch astronomer, Christiaan Huygens, using a…

employed for military applications by the US Army performing search and patrol operations. In 1921 the US Army acquired the Italian semi-rigid airship “Roma”, the largest semi-rigid airship in the world. After its crash in 1922, the US started to use helium instead of hydrogen as the lifting gas. Another important Italian airship in the history was the semi-rigid airship “Norge” (Figure 1 1) that carried out what many consider the first verified over flight of the North Pole on May 12, 1926.…

T he Hindenburg Disaster occurred 79 years ago today. On May 6,1937 in Lakehurst, New Jersey the world’s largest aircraft ever built caught fire and burned to the ground in seconds. The Hindenburg was a zeppelin aircraft. Zeppelins were made of helium but for some odd reason the Hindenburg was made of hydrogen, a very flammable gas. The Hindenburg was over eight-hundred feet long and carried over 2656 people across the Atlantic between Germany and New York and Rio de Janerio before the…

This project is over a career that i would want in the future. In this paper i will be writing about welding. First i will tell you what welding is. Welding is the act of fusing metal together by basically melting the metal together. Welders can be found anywhere in the world. If there is something to be built with metal you’ll find a welder there. There are several different duties of being a welder. You must be able to read blueprints, be able to read a tape measure, maintain equipment such…
