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, ...

- Throughout the ages we have seen timeless inventions to numerous to name. We have seen everythingfrom the inventio of the radio to the engine to the atomic bomb. But there is one invention that goes onunappreciated, even looked down upon. The toilet. The toilet is an amazingly simple invention which,without it, the world would be a very different place. Without toilets there would be waste in our housesas well as in the streets that would have to be manually taken care of. Without the flush toilet there is nopossible way that the world could survive as populated as it is.... [tags: physics toilet toilets]

- ABSTRACT Several researchers have devoted efforts on studying physics of arc and descriptive models are used to explain many arc welding related phenomena. However, due to the subject complexity, doubts still emerge about the mechanisms of some phenomena related to the arc. For instance, the description about electromagnetic interactions with the arc, which governs the arc trajectory and lead to plasma jet and arc blow formation, seems to be yet controversial. Thus, the present study aimed a better understanding of these phenomena.... [tags: Physics ]

- The Physics of Fishing The use of a boat while fishing and some of the physics applicable to boating will be included in exploring the various ways physics applies to the sport of fishing. Other topics will include the fishing rod, fishing lure, casting, and the fish itself. The boat floats on the water according to Archimedes Principle which states an immersed object is buoyed up by a force equal to the weight of the fluid it displaces. The force applied downwards by earth’s gravity coupled with the upward force of buoyancy allows the boat to float.... [tags: Physics ]

- i: Introduction You apprehensively walk up the iron steps and onto the platform. You’re reluctant to go any further, but your friend eggs you on, saying, “It’s not that fast.” You step into the seat and pull the harness down over you. No, this isn’t the latest, greatest technological frontier. It’s a roller coaster. Since 1804 when the first wheeled roller coaster- called “Les Montagnes Russes”- was constructed in Paris, France, roller coasters have been a staple of adventure and fantasy among children and children-at-heart....

- A roller coaster is a thrill ride found in amusement and theme parks. Their history dates back to the 16th century. It all started in Russia, with long, steep wooden slides covered in ice. The idea then traveled to France. Since the warmer climate melted the ice, waxed slides were created instead, eventually adding wheels to the system. The first roller coaster in which the train was attached to the track was in France in 1817, the Russess a Belleville. The first attempt at a loop-the loop was also made in France in the 1850s....

- INTRODUCTION Physics attempts to describe the fundamental nature of the universe and how it works, always striving for the simplest explanations common to the most diverse behaviour. For example, physics explains why rainbows have colours, what keeps a satellite in orbit, and what atoms and nuclei are made of. The goal of physics is to explain as many things as possible using as few laws as possible, revealing nature's underlying simplicity and beauty. Physics has been applied in many industrial fields, which include the air industry, construction industry, automobile industry, manufacturing industry and many others.... [tags: Physics]

- Basic Concepts Issac Newton was the first to state the concepts that are necessary to understanding the physics of collisions. His three laws are used again and again in all the fields of physics: Newton's 1st Law In the absence of external forces, an object at rest remains at rest and an object in motion remains in motion with a constant velocity. This law can be best observed in space, far from the gravity of a star or planet, where there is no friction or air resistance. If, in the middle of deep space, you give a rock a little push, it will continue with the direction and velocity you gave it forever.... [tags: Physics]

- Remote Sensing is the science of acquiring, processing and interpreting images that record the interaction between the electromagnetic energy and matter (Sabins, 1997). Remote sensing offers extensive applications in almost every area of science from monitoring forest fires to geologic mapping . Although many aspects of remote sensing are complex and difficult to understand the basic theory behind remote sensing is simple physics. There are four major stages of remote sensing. The first stage is the source of energy, usually the sun, which sends energy to a target.... [tags: Physics]

- The Mirrors of Classic Physics Plenty of conceptions of mirrors are not so different from models in middle school physics. The mirror is a line dividing the ‘real’ from the ‘virtual’, and the image is the same on both sides. It is a plane in three-dimensional space, a slash in textual space, and a boundary to fluid spaces. In physics class, rays of light go from each point of the image and bounce off the mirror in such a way that they seem to have come from the virtual object. These are not the only mirrors....

- The great Greek thinker Aristotle was born in 384 B.C. in Stagirus, a city in ancient Macedonia in northern Greece. At the age of eighteen Aristotle went to Athens to begin his studies at Plato's Academy. He stayed and studied at the Academy for nineteen years and in that time became both a teacher and an independent researcher. After Plato's death in 347 B.C. Aristotle spent twelve years traveling and living in various places around the Aegean Sea. It was during this time that Aristotle was asked by Philip of Macedon to be a private tutor to his son, Alexander.... [tags: physics aristotle]
