The Physics of a Toilet
Almost everyone in America has used, is using at this very moment or will use a flushable, indoor toilet. Their privacy, and in some cases cleanliness, are taken for granted day by day. The basic physics of siphoning, and the right amount of water, makes the toilet operate in our desired fashion. This has been the concept of toilets for over 200 years. Some questions do come to mind when witnessing this event; how does the water and waste get sucked out of the toilet bowl? Why does the water get sucked out in a spinning motion? Does it matter which side of the hemisphere creates a certain trend of spin in the water? These phenomena are more common than one may think, these things happen through a variety of home appliances. I'm going to try to concentrate on the basic physics of the toilet, but first, here's a little bit of toilet history for you.
The oldest toilets that used water to dispose of waste have been discovered on the Mediterranean Island called Crete; these toilets are known to be made around 2000 BC.
During the time frame of the 5th century to the 15th century, disposing of waste into the street was the only way to get rid of the waste. This was extremely dirty and unhealthy. Sir John Harrington developed a flushable water closet for Queen Elizabeth I in 1596. A watchmaker named Alexander Cummings enhanced the design of the toilet in 1775. Making the water trap to stop the flow of foul odors coming back through the pipes. Thomas Crapper then came along in the 1800's and polished up all of the inner workings of the toilet, leading to what is still used today in our toilets.
There are three fundamental mechanisms of the toilet. Without one of these mechanisms working correctly, ...

Tommy Douglas is known as a prolific politician but considering his contributions that is a huge understatement. He can be seen as a role-model for all generations to come. When Tommy Douglas was asked why he stayed with the NDP (National Democratic Party) when he could have been more successful with a more powerful party he replied “I have watched politicians for the last forty years drop their principles in order to get power only to find that those who paid and controlled the party which they joined prevented them from all the things they really believe in”. To the end of his days Tommy Douglas was true to himself, to ...
A sports writer investigated the scandal and later wrote a famous article called “Is Big League Baseball Being Run for Gamblers WIth Players in the Deal.” The White Sox owner quickly avoided the rumors by saying that ”I believe that my boys fought the battles of the recent World Series on the level.” He wanted to avoid people knowing that he had been tipped off about the scam for the World Series.
The 1919 World series resulted in the most famous Scandal in Baseball history. Eight players from the Chicago White Sox were accused of throwing the series against the Reds and were banned from Major League Baseball. (“History files-Chicago Black Sox”) All eight players were expelled in an attempt to save the purity of the game. The White Sox lost the opening game of the series nine to one, and then ended up losing the series five games to three. (“Black Sox Scandal”) They had won the American league pennant and were highly favored to beat the Reds in the World Series. (“Bankston, Carl. L”)
This Black Sox Scandal trial was a very interesting trial I had wanted to know about for the longest time. In writing this paper I mainly referred to the site, http://www.law.umkc.edu/faculty/projects/ftrials/blacksox/blacksox.html
...used to spread capitalism and exploit the government of another country. It seems war doesn’t change so much, seeing how what happened in Chile and Argentina isn’t so different from what happened in Iraq and the war on terror it is eye opening to see the Iraq war being another example of the use of the shock doctrine since in the past I was told and honestly believed it was a necessary course of action after 9/11. Even worse is how the economy crashing in 2008 being used to leverage laws and changes in the government that would certain benefit the rich and affluent. Deregulation happened in America a long time ago, and it is clear what has happened as a result I see things such as Occupy Wall Street more as necessary calls to action on the con's of regulation and to call upon reforms and changes so poverty doesn't rise or violence erupts just like in Chile or Iraq.

The Black Sox Scandal of 1919 remains the most infamous scandal in baseball's storied history. The fix exemplified the desperate position in which the United States had been in at the time. It is quite saddening to hear how selfish men can become when money is put in front of them. They not only drastically altered their own lives, but they also affected many more lives around them. The Black Sox Scandal will remain in history as one of the most disgusting series of events to ever occur in Major League Baseball.
Problems with sewage and garbage management as been in existence for as early as the 1970's as a result of the general concern expressed by people that worried about the increasing pollution in the human environment. But it even goes further then that. Ancient people have been finding ways of resolving sanitation. An ancient sewer system was found in the cities of Crete and Assyrian.
Sanitation was not top priority in ancient times. The latrines were placed in public areas allowing ten to twenty people at a time, with no privacy. Toilet
...'s Children, is an important tool in the education of teachers to help them to see teaching is not a politic-free practice that has little to do with social justice. Through reading multicultural theorists like Delpit, teachers are better prepared to deal with the issues like injustice and "remove the blinders built of stereotypes, mono-cultural instructional methodologies, ignorance, social distance biased research and racism" in the classrooms (Delpit, 1995, pg.69).
Paul Laurence Dunbar’s “We Wear the Mask” is a lyric poem in which the point of attraction, the mask, represents the oppression and sadness held by African Americans in the late 19th century, around the time of slavery. As the poem progresses, Dunbar reveals the façade of the mask, portrayed in the third stanza where the speaker states, “But let the dream otherwise” (13). The unreal character of the mask has played a significant role over the life of African Americans, whom pretend to put on a smile when they feel sad internally. This ocassion, according to Dunbar, is the “debt we pay to human guile," meaning that their sadness is related to them deceiving others. Unlike his other poems, with its prevalent use of black dialect, Dunbar’s “We Wear the Mask” acts as “an apologia (or justification) for the minstrel quality of some of his dialect poems” (Desmet, Hart and Miller 466). Through the utilization of iambic tetrameter, end rhyme, sound devices and figurative language, the speaker expresses the hidden pain and suffering African Americans possessed, as they were “tortured souls” behind their masks (10).
Paul Laurence Dunbar was one of the first black poets in his time to confront the hypocrisy he saw around him. “We wear the mask” was one of his outstanding works that addressed racial injustices in American society. This poem was all about the assertion that “we wear the masks” to hide their true feeling. Yet, he goes on to emphasize that the ruthlessness of suffering and pain that these masks try to cover up because they had to keep all the pains by themselves without expressing. According to William Carroll, “The poem closes with a repetition of a sentiment stated earlier: ‘But let the world dream otherwise, / we wear the mask!’ The people show a dogged determination to keep the true nature of their sufferings to themselves and to present to others an outward show of happiness and lack of care. Surely, such insistence on deception must be motivated by powerful feelings resulting from terrifying experiences. Such were the experiences of many people enslaved in the United States before the birth of this poet” (1-2). Because of their racial appearance and experience in injustice society, they have to hide their feeling.
In the late 19th century, African-Americans suffered pain, frustration, and anguish caused by Caucasians, as well as from one another. For African-Americans to openly voice the violence they faced from Caucasians would result in a dangerous aftermath. Sometimes, African-Americans would hold their true feelings from each other because they didn't want to be judged or cause uproar. So they stayed silent letting all this happen to them, Paul Laurence Dunbar helps all those who lost their voice in the violence regain it, in the his poem “We Wear the Mask”.
In 1874 William Blackstone, a Bluffton, Indiana merchant and manufacturer of corn planters, built a birthday present for his wife. It was a machine that removed and washed away dirt from clothes. It consisted of a wooden tub in which there was a flat piece of wood containing six small wooden pegs. The inner mechanism looked something like a small milking stool. It was moved back and forth by means of a handle and an arrangement of gears. Dirty clothes were snagged on the wooden pegs an...
