How does author Elie Wiesel use symbolism to contribute to the meaning of Night?

In his book Night, Elie Wiesel uses symbolism throughout to enhance the text. First of all, the title itself is symbolic. The word "night" is repeated several times in different contexts. Night is death. Night is when one cannot see what is coming. It is a frightening time, especially for the Jews in concentration camps. They never know what is going to happen next. Some examples:

"Night fell." (Wiesel 10)

"An endless night." (Wiesel 24)

"As soon as night fell, she began to scream." (Wiesel 24)

"Never shall I forget that night, the first night in camp, which has turned my life into one long night, seven times cursed and seven times sealed." (Wiesel 32)

Another symbol in Night is fire. Early on, Madame Schacter sees fires burning in a vision she experiences as the Jews are transported on the train. The other Jews think she has lost her mind, but when they arrive at Auschwitz, there it is. The fire that burns people alive is right in front of them. Fire also symbolizes Wiesel's feelings about God.  God is gone--burned up like a fire and no longer present as far as Wiesel is concerned. And most significantly, fire is symbolic of the living Hell in which the Jews barely exist.

These are just two of the many symbols found in Night; each has an important meaning and gives Wiesel's story power.

In his last battle Beowulf fights against?

Beowulf's final battle is against a dragon who has invaded Geatland and has begun to ravage the countryside. It has been fifty years since Beowulf defeated Grendel and his mother, and the old king suits up for battle one final time. Beowulf and his kinsman, Wiglaf, enter the dragon's tower and assault the beast. Beowulf's sword, Naegling, breaks as he strikes the dragon; the dragon capitalizes on this and bites Beowulf. Wiglaf lands a blow on the dragon, and Beowulf uses his dagger to wield a mortal strike on the dragon. Beowulf was again victorious; unfortunately, the dragon's bite was poisonous, and the valiant king soon dies. Before he dies, Beowulf appoints Wiglaf his successor. Wiglaf and his men give their king a glorious funeral.

What is Yeats' claim about the Second Coming?

In "The Second Coming," W.B. Yeats explores the Second Coming, a traditional Christian idea that prophesies the return of Christ and the salvation of all true believers. However, Yeats turns this idea on its head by claiming that the Second Coming will be a violent apocalypse, rather than a sign of salvation.

To understand Yeats' main claim in "The Second Coming," it's first important to understand the historical context in which the poem occurred. The poem was published in 1920, a significant year for all Europeans, and especially for the Irish. The chaos of World War I had recently ended, leaving Europe in a state of previously unimaginable ruin. To make matters worse, Ireland was in the middle of a war for independence that began in 1919 and would last until 1921. As such, it's easy to imagine that, for an Irishman like Yeats, the world must have appeared to be crumbling.

When Yeats envisions the Second Coming, he imagines a "blood-dimmed tide" (5) and a monstrous, beastly "nightmare" (20), a "rough beast" (21) slouching "towards Bethlehem to be born" (22). This vision is a far cry from Christianity's traditional vision of peace and salvation. Indeed, Yeats is basically claiming that the Second Coming will embroil the world in a bloody, apocalyptic event. In the face of the unprecedented chaos and violence of Yeats' day, such a grim assertion would have made sense, as it must have seemed as if the world was ending.

Why does Atticus visit the Radley house?

In Chapter Eight, Atticus visits the Radley house to offer his condolences to the Radley family after Mrs. Radley passes away.

Although Jem and Scout both think that Mrs. Radley died at the hands of Boo Radley, Atticus dispossesses them of this entertaining theory. He tells the children that Mrs. Radley died of natural causes. When she was alive, Mrs. Radley seldom appeared in public; she was only seen when she came out to water her flowers.

Despite Atticus' words, Jem and Scout are still curious about a particular member of the Radley family. They proceed to ask their father the one question that is uppermost in their minds: Did Atticus see Boo Radley when he went to pay his respects at the Radley home? Atticus answers in the negative, however, and this disappoints the siblings.

Although Scout is tempted to ask Atticus to clarify his statement, Jem discourages her from doing so. He thinks that it's wise not to antagonize their father. After all, Atticus may possibly suspect that they weren't actually playing strip poker near Miss Rachel's fish-pool on that fateful night Mr. Radley shot off his gun in his collard patch. Jem doesn't want Atticus to discover that he, Dill, and Scout were on the Radley property trying to get a glimpse of Boo that night.

Does density affect the evaporation rate of a liquid?

Density does affect the rate of evaporation. Liquids with a higher density have a lower rate of evaporation. This means that honey will have a lower rate of evaporation as compared to water, which will have a lower rate of evaporation as compared to alcohol. This is because honey is more dense than water, and water is more dense than alcohol.

One way to think about how density affects the rate of evaporation is to consider the relationship between density and intermolecular forces. Denser substances have higher intermolecular forces, which causes molecules to be closer to each other. This means that more heat needs to be supplied to overcome these strong intermolecular forces. Hence the rate of evaporation is slow for denser materials as compared to less dense materials. 

Apart from density, other features such as the molar mass also impact the rate of evaporation.

Hope this helps. 

What do you see as some important pros and cons of both primary and secondary research?

Primary research can be a very good way of getting information, but you have to be careful. The first potential problem applies to translated texts; translators always put some of themselves in the works they do by translating certain words or phrases in their own way, which can change the meaning of the work drastically. But you also have to be wary of the original author's bias, so even the original language is risky. Reading a primary work allows you to make your own conclusions, to read between the lines to try to figure out what the author and/or translator meant; that is very helpful because you know you'll get exactly what you're looking for without it being affected by the input or bias of someone else. Primary sources can be exhausting because you have to take everything they say with a grain of salt; you have to question everything they write, think about why they wrote what they did. And yet they are the purest form of information.

Secondary research can be easier to read, and it makes less work for you because someone else has already gone through the painstaking effort of analyzing the primary source. It is also a good way to back up your own claims because it shows that someone else agrees with you. However, it can be difficult to find secondary sources on exact topics, particularly if you are researching something very specific. You also have to worry about yet another layer of potential bias that you have to take into account.

Overall, I have always preferred primary sources because they are the least removed from whatever you are studying, the closest you will get to an eyewitness account. I tend to come up with my own claims based on my primary research, and then do the secondary research to find others to back up my opinions. But you can also do it the other way around.

Who are Romeo and Juliet?

Romeo and Juliet, the titular characters of William Shakespeare's play, are the children of two wealthy families of Renaissance Verona. Though they are only in their teenage years, these two are considered full adults and both are expected, by their parents, to be married soon. 

Romeo is a very introspective and dramatic young man. He is, "in love with love," or wishes to be in love. Early in the play, we learn that he is infatuated with a girl called Rosaline. Nonetheless, he falls in love with Juliet upon sight. Perhaps his wish is really to appear to be in love without genuinely establishing a relationship with someone.

Juliet is a little naive, having little social experience outside her own family. Over the course of the play, she grows more sure of herself, but her desire to be with Romeo leads her to making hasty decisions.

The most important thing to know about Romeo and Juliet as characters is that they are the only children of two feuding families. They are expected to be sworn enemies, but they fall in love before ever learning one another's names. This is what makes their relationship so difficult- they can never tell their families that they are in love with the enemy! This conflict drives the play and ultimately leads to the two lovers taking their own lives.
