John Dalton's Atomic Theory Essay Example | Topics and Well Written Essays - 1000 words

John Dalton's Atomic Theory - Essay Example John Dalton, born in the 18th century is known as the father of Atomic Theory and is mainly known for his work on the atomic theory and Dalton’s Law for partial gases (Fishman, 2008). By education he was a chemist and later shifted his focus on researching and meteorology. Even though, today advanced research has shown that Dalton’s theory was not absolutely correct, yet we cannot forget his pioneering work that encouraged others to think on the same lines and made progression in the field. After the proposed theory and up to this day any work in the fields of physics or chemistry is very much rooted in the theory. Dalton, was very much fascinated with the properties of gases. It was while doing research on meteorology that we concluded that when water evaporated it existed as an independent gas. He explained that unless both water and air were composed of the same discrete particles it was not possible for both to exist in the air together. This encouraged him to perform a series of experiments with gases, following which he proposed his atomic theory. While introducing his concept he published in the book A New System of Chemical Philosophy that â€Å"We might as well attempt to introduce a new planet into the solar system, or to annihilate one already in existence (Dalton, 1808). In short Dalton proposed four main concepts. Firstly, all matter is made up of minute and indestructible atoms. Secondly, all atoms in similar elements have identical chemical and physical properties. Next he also said that compounds are made up of atoms combining in a fixed ratio and lastly, he proposed that chemical reactions merely include the rearrangement of the constituent particles (Thompson, 1807). On a personal level, I think that Dalton’s work is truly pioneering and phenomenal since a simple evaporation of water instilled questions in his mind about the existence of smaller particles. One of the major drawbacks that can be seen in his experiments is that

Media And Terrorism Research Paper Example | Topics and Well Written Essays - 500 words

Media And Terrorism - Research Paper Example Pandalai and Institute for Defense Studies and Analyses (2013) argue that several characteristics make the media to be well suited for terrorist and terrorist activities. One important characteristic that is important for terrorism as related to the media is that it sets the agenda in that the more attention one pays to a certain activity like terror attacks, the more importance and attention the public pays attention to it. Moreover, the way a news item is offered or outlined determines how it will be explained or understood by the target audience or population. It is a matter of fact that terrorists and their terror activities would want to be in the media most probably in a positive way to be seen as fighting for a political, ideological or political cause. The media becomes an important tool for setting and framing this agenda as wanted by the terrorist.  Terrorists adopt the use of the media to set and propagate some of their objectives of terrorism, Whitehead (2013) argues th at terrorists may use the media for purposes of seeking attention, recognition, and legitimacy, which can be achieved through the psychological interaction between them and the media to demoralize enemies. In order to achieve this, terrorists try to gain the attention of the audience to condition their thinking thus creating fear; afterward, they seek for recognition of their motives in order to gain sympathy and respect before using the media to gain quasi-legitimate status to be recognized as important political players. Terrorists participate at several levels in the media either when the media reports a terror attack, when terrorists send their messages through the media or when they have a full control of the media outlet. In the first case, the terrorists carry out an attack and wait to see how the media carries out the story or report it, while the second scenario occurs when those involved in the terror activity send their message to the media after framing their message.
