The bald eagle, Nike, the structure of government buildings and libraries, what do these things have in common you ask? The answer is quite simply that they were all influenced from something in Greek Mythology. Greek mythology and Greek culture in general have had a major impact on American culture. “You can’t walk to any U.S city without seeing something that has been influenced by the Greeks,” says Chiron, a character from one of Rick Riordan’s, popular writer of the Percy Jackson books…

Nucleophilic substitutions are a fundamental class of reactions in organic chemistry. This type of reaction involves a nucleophile, or an electron rich species, attacking an electrophilic site, or an area that carries a positive or partially positive charge, in order to replace a leaving group. There are two possible mechanisms to account for the attack of the nucleophile; the first occurs in a concerted process, or in one step and the second mechanism occurs in two steps and involves a…

Sam Kean, a Washington D.C. writer with works in The New York Times Magazine, Mental Floss, Slate, The Believer, Air & Space, Science, and The New Scientist, has created a user-friendly book about how to explain the periodic table and the elements that occupy it by writing the book The Disappearing Spoon: And Other True Tales of Madness, Love and the History of the World From the Periodic Table of Elements. He provides an insight into the world of chemistry that relates to his audience, even…

The periodic table of elements contains about 118 elements, and there are also many trends in the periodic table, such as ionization energy, electronegativity, and many other trends. When Dmitri Mendeleev created the periodic table, not all of the elements were present. It took many other scientists to discover the other elements. Mendeleev started to notice the patterns in the properties and atomic weights of halogens, alkali metals, and alkaline metals. He created a card for each of the 63…

Thesis for Research Paper Throughout life, there are certain technological advancements everybody experiences which affect their lives in either positive or negative ways. To be more specific, the field of photography is a field which has had some major technological advancements with imaging, resulting in the discovery of radiographs, computed tomography and magnetic resonance imaging. The chain reaction of advancements from photography to medicine has helped the world in increasing life…

The periodic table had been a key factor in many ways to finding new elements, like scandium, silicon, and neon. It has shown new ways those elements could help us by predicting certain elements reactions. While Dimitri Ivanovich Mendeleev is considered to be the creator of the periodic table, there were many contributions that helped the creation of the useful graph be achieved. Between 1817 and 1829 Johann Dobereiner was grouping elements with similar properties into groups of threes,…

Sophie’s Choice was released in 1982 and quickly gained praise as a dramatic romance film. The storyline is based on the 1979 novel of the same name by American writer William Styron.

wrinkle-resistant, or less flammable. Some of these chemicals are carcinogenic or may cause harm to children even before birth. Others may trigger allergic reactions in some people. Some flame retardants that are used in certain textiles contain organic bromine compounds that are persistent (break down very slowly in the environment). The use of some dangerous chemicals in textiles is restricted such as azo dyes and formaldehyde. All textiles processes have an impact on the environment. The…
