Gatsbys Revelation essays

Gatsbys Revelation essays When F. Scott Fitzgerald wrote the novel The Great Gatsby, he used a unique writing technique. It used a first-person point of view in the form of a narrator, Nick Carraway, who was also involved in the story. This style allowed the author to withhold any information that he did not present to the narrator in the story, causing the reader to learn things the same way the narrator did. The protagonist in The Great Gatsby, Jay Gatsby, was revealed to the narrator, Nick, gradually throughout the course of the novel. On the surface, Jay Gatsby appeared to be extremely wealthy and generally happy with his place in life, and this is how he appears to Nick at the beginning of the novel. Gatsby threw big parties and people were not invited; they just showed up, as explained by Nick on page 45: "I was one of the few guests who had actually been invited. People were not invited-they went there"(45). As Nick began to know Gatsby better, he began to realize there was something wrong with Gatsby. Gatsby was obviously unhappy, but the reader was not told why. When Nick goes to New York with Gatsby and meets Meyer Wolfshiem, the reader is given some suspicion that Jay is involved in illegal dealings, because of the hints that Meyer Wolfshiem drops and the things Jay tells Nick about Meyer. The reader is finally told why Gatsby is unhappy at the end of chapter four, when Jordan Baker tells Nick about Gatsby's love for Daisy. The next major revelation about Gatsby does not happen to Nick until much later, but the author decided to place it earlier in the novel so the reader could understand what was going on more easily. Jay Gatsby tells Nick about where he came from, how he got there, and why he got there. Nick realizes that Gatsby is so in love with Daisy that he is crazy and will do anything to get her. It has consumed his life so much that he spent five years leading an illegal life just because of her. Th ...

Definition of a Phase Diagram

Definition of a Phase Diagram Definition: For a given substance, it is possible to make a phase diagram which outlines the changes in phase (see image to the right). Generally temperature is along the horizontal axis and pressure is along the vertical axis, although three-dimensional phase diagrams can also account for a volume axis. Curves representing the Fusion curve (liquid/solid barrier, also known as freezing/melting), the Vaporization curve (liquid/vapor barrier, also known as evaporation/condensation), and the Sublimation curve (solid/vapor barrier)) can be seen in the diagram. The area near the origin is the Sublimation curve and it branches off to form the Fusion curve (which goes mostly upward) and the Vaporization curve (when goes mostly to the right). Along the curves, the substance would be in a state of phase equilibrium, balanced precariously between the two states on either side. The point at which all three curves meet is called the triple point. At this precise temperature and pressure, the substance will be in a state of equilibrium between the three states, and minor variations would cause it to shift between them. Finally, the point at which the Vaporization curve ends is called the critical point. The pressure at this point is called the critical pressure and the temperature at this point is the critical temperature. For pressures or temperatures (or both) above these values, essentially there is a blurry line between the liquid and gaseous states. Phase transitions between them do not take place, although the properties themselves can transition between those of liquids and those of gases. They just do not do so in a clear-cut transition, but metamorph gradually from one to another. For more on phase diagrams, including three-dimensional phase diagrams, see our article on states of matter. Also Known As: state diagram, change of phase diagram, change of state diagram
