Welding has been for many year from the middle ages. In the middle ages welding was known as blacksmithing. Blacksmithing is the technique of forging wrought iron and steel. Blacksmiths made horseshoes, weapons, and repair armor. Blacksmith get there name because they were smith and worked with black metals like tin, silver, and gold. With the work they do they need shatterproof hammers and handles because most of their work is forging metals with these hammers. In the middle ages blacksmiths…

Thesis Statement: During their existence, stars form when the density of interstellar gas and dust, which form molecular clouds, reaches a certain point, and die by collapsing and turning into a white dwarf or a neutron star. Stars can fail and become a brown dwarf. Stars form when the density of the concentration of molecular clouds collapses and reaches a certain point. These regions are usually extremely cold and contain carbon and hydrogen. However, not all materials from the clouds form…

In the process of TIG welding an arc is formed between the tungsten electrode and the metal that needs to be welded. A gas is fed through the torch to protect the electrode and molten weld pool. The gas is usually made up of argon or helium and this gas protects the electrode and the weld metal from the surrounding atmosphere. Extra filler wire may be added to the weld pool if required and this will also be protected by the gas shield. TIG welding requires a skilled craftsman to achieve…

to its spectral models of previously suggested atmospheric models of WASP-12b. They found that the data didn’t match either of the two currently proposed models. The new data indicated that the atmosphere of WASP-12b is made of atomic hydrogen and helium. WASP-12b is only the second planet to have spectrally resolved albedo measurements. The data let the scientists determine whether the planet reflects more light towards the blue or the red end of the spectrum. WASP-12 emits light because of its…

Corporation Recall is the largest in human history. The problem (more often than not) originates in the steering wheel, more specifically the airbag. An airbag is like a really cool balloon, instead of someone blowing it up, or inflating it with a helium tank; an explosion takes care of that. The idea is that the explosion fills the balloon with nitrogen and a wave of concussion, but only for the moment of a crash then the airbag generally deflates. For the most part, airbags are a great safety…

of financial problems at the time, Chris could not afford mixed air, oxygen mixed with other essential gasses that lessened the narcosis effect, because of the recession in the economy. They were diving on regular air, composed of merely oxygen and helium. Most divers would not dare to do so, especially at such a depth of three hundred feet. After Chrissy ventured into the submarine, a large metal shelf fell and pinned him down. His screams for help alerted father and Chris rushed to help his…

Neptune is one of the four large planets in our Solar System known as Gas Giants. It is the eighth planet in order from the Sun, and was seen through a telescope for the first time on the 23rd of September 1846. Keeping to the traditional naming system used for all the previous planets, Neptune was given its name based on the Roman god of the sea, in reference to Greek and Roman mythology. General Information: Neptune has a vivid blue colouration to its layer of cloud cover. Higher…

from a necessary draft. In the year 1961 a group of women called Women Strike for Peace protested around the United States with more that 50,000 members with the intention of having President John F. Kennedy sign laws that gave women more equality(Helium 1). By May of 1968 the war in Vietnam had gotten worse, in one week 562 troops had been killed and atrocities against innocent children were committed in South and North Vietnam due to daily bombing raids(History Learning 1). News of the deaths…

The state of energy production throughout the globe is experiencing the concern of availability and access to resources that aid in the production of needed energy, but also reducing the presence and production of carbon dioxide emissions. What is typically understood among nations invested in nuclear energy is that such technology is largely free of carbon dioxide emissions at the source of production- a favorable avenue in context to fossil fuel utilization, but is historically rot with…

well as more neutrons. These neutrons then go on to split more nuclei and a chain reaction takes place. Fusion is basically the reverse process of fission. In this situation the nuclei collide instead and join together to form an atom larger than helium. Nuclear power plant use fission to produce very large amounts of energy. Enough to provide most of the world with electricity. It may sound like a great method, but it has many downfalls such as production of radiation that has been proven to…
