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, ...

In high school I worked at Jimmy Johns and have had to clean up after customers that have defecated on the floor next to the toilet. At the Men’s Wearhouse in Sioux Falls where my fiancée works, people have rented suits and returned them after defecating inside the suit. At the Kmart that my stepdad worked at for twenty years, elderly customers have not been able to make it to the bathroom on time and leave a streak down the aisles to the restroom. At the Starmark in Sioux Falls where my father was employed for many years, employees defecated in the corner of the factory bathroom. My father also worked on many construction sites around Sioux Falls where other workers would urinate in a bottle, place the bottle in the wall, and build around it. My father also worked on an apartment complex renovation where the tenants of the building defecated on the newly-carpeted hallways and proceeded to smear it on the freshly-painted walls. These stories provide some insight on the public defecation phenomenon in that it is not localized to one specific area or just large populated

...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.
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.
Throughout African American history, African Americans have used poems as a way of describing the African American condition in America. One poet who was widely known for using poetry to describe the condition of African Americans in America was Paul Laurence Dunbar. Paul Laurence Dunbar was one of the most prolific poets of his time. Paul Laurence Dunbar used vivid, descriptive and symbolic language to portray images in his poetry of the senseless prejudices and racism that African Americans faced in America. Throughout this essay I will discuss, describe and interpret Sympathy and We Wear the Mask. Both Sympathy and We Wear the Mask were written by Paul Laurence Dunbar.
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”.
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
In ancient Rome, latrines were often affixed to the public bathhouses and were constructed with necessity in mind rather than privacy. Side by side seats were constructed of pierced stone or wood and placed above a stream of water supplied from the sophisticated aqueduct system for which the Romans were well known. These seats were not enclosed individually as are modern toilet facilities, but rather in long rows quite close together. Lacking the commercial toilet tissue as we know today, the Roman therefore used sponges on sticks for the purpose of personal cleansing. However, these were shared by everyone with minimal rinsing between uses in a small stream of water which ran in front of the latrine.
Because of insufficient and poorly trained staff commonly found in nursing homes. Care givers are often overworked and grossly underpaid, which often results in rude and abusive behavior towards vulnerable residents who beg them for simple needs such as water or to be taken to the bathroom. Federal and State laws require that nursing homes develop a plan of care and employ sufficient staffing to provide all the care listed in the care plan. Most corporate-owned nursing homes today are not sufficiently staffed, and they can not provide all the care listed on the care plan. Consequently, residents are not taken to the toilet when necessary; they’re often left lying in urine and feces.
As an educator one must understand that the children you will be teaching will all come from different backgrounds, different ethnicities, different homes with different values. No one student will be the same, and no one student will learn the same. The role of a modern educator is to harness this idea of diversity and channel it into a positive learning atmosphere for children of all backgrounds. “I define culturally responsive teaching as using the cultural knowledge, prior experiences, frames of reference, and performance styles of ethnically diverse students to make learning encounters more relevant to and effective for them” (Gay, 2013, p.50.). The hope for all teachers is to capture the minds of their children, as educators we must learn how our students learn, adapt to their skill set and channel our curriculum to their strength.
“We Wear the Mask” is a short poem written by Paul Laurence Dunbar in 1895. It is written in iambic tetrameter and has many symbols throughout its stanzas. These symbols show the struggle that black Americans have to live with in society, and the hardships they face on a daily basis. The symbols that are portrayed throughout this poem could be identified as the mask, the smile, the word we. This paper will be discussing how the use of these symbols makes this poem a relatable piece, even in this modern day, as the struggle for black Americans to live happily continues to exist.

When it comes to a running toilet, many homeowners ignore it. They consider it a little problem they’ll get to eventually. However, a running toilet is a costly problem that should never be ignored. If you have a leaky toilet, then there are real cost to your each month and real cost to the environment each day.
