Physics Relevance Essays - Acceleration, Aether Theories

Physics Relevance By [emailprotected] One aspect of physics in my life is gravity. Whenever I loose my balance, whether I'm on a bike, walking, or trying to stand on one leg, I will fall down. This is because every mass is attracted to every other mass, so my body is attracted to the earth, and the earth is attracted to my body, only not as much, because my body has a much smaller mass than the earth. This is also why when I drop something; it falls down, instead of just floating there like it would in space. This is very important in my life, because if I am not careful or if I start ignoring this aspect of physics I will fall, and end up with a bunch of bruises. This is also why when picking something up, or carrying something, I have to be careful not to drop it or break it. There is also a chance that gravity will cause something to fall on top of me, and that would hurt. This all may sound like a bad thing, but actually gravity has many good uses to, like with out gravity it would be very hard to find anything, because everything would just float away. It would also be a lot harder for people to get around, because cars wouldn't be able to ride on the ground. And we also wouldn't be able to walk, we would have to bounce from one place to another, and there would probably be a lot of midair collisions because people would not be able to control themselves. But if you think about it, these problems would not even exist if there was no gravity, because that would be nothing holding earth around the sun, so we would all freeze to death. The earth would also have no atmosphere, so we would not be able to breathe anything, and we would all suffocate.

Prodigal vs. Prodigy

Prodigal vs. Prodigy Prodigal vs. Prodigy Prodigal vs. Prodigy By Mark Nichol Prodigal means â€Å"to spend wastefully.† So, what does that have to do with the biblical parable of the prodigal son, and what does being prodigal have to do with being a prodigy? As it happens, there’s no connection between the two words, though an assumption that they are synonymous may lead some people to believe, erroneously, that the phrase â€Å"prodigal son† refers to an impressive young man. For those of you who have forgotten, or never learned, the story of redemption from the Bible, the younger of two sons prematurely demands his inheritance from his father. The older man complies with his wishes, and the youth leaves home, where he foolishly fritters away his fortune. Reduced to penury, he returns home, prepared to beg for forgiveness, but his father welcomes him and causes for a celebration. When the older son bristles at this injustice, for he has worked hard in his father’s service and has received no preferential treatment, the father explains that they should rejoice that the younger son has returned to the family fold. Prodigal, which is derived from the Latin term prodigere, which means â€Å"to drive away or squander,† also means â€Å"lavish,† and in addition it has a sense of luxuriance that may, depending on context, be negative, neutral, or positive. However, the word is usually employed to allude to the parable in references to a redeemed returner as a prodigal son. Prodigy, by contrast, is from a distinct Latin word, prodigium, meaning â€Å"omen or monster† (both of which stem from a precursor word that means â€Å"to warn†). The most common sense of prodigy is in reference to an unusually talented young person, although, more rarely, yet with more fidelity to its Latin roots, it may also mean â€Å"something extraordinary or inexplicable,† or â€Å"a great accomplishment.† Another rare usage is as a synonym for omen. The adjectival form, prodigious, has lost its connection with omen (portentous is often, in its place, applied to omens) and means â€Å"strange or exciting† or, in keeping with the connection to monster, â€Å"enormous.† Want to improve your English in five minutes a day?

What is the evidence on Parents or Family role in Childhood Obesity in Literature review

What is the evidence on Parents or Family role in Childhood Obesity in UK - Literature review Example According to the BHF (2012), at least 33% of girls and 25% of boys aged 2-19 years in the UK are obese. That notwithstanding, it is projected that the prevalence of childhood obesity will be around 10.7% or higher by the years 2015 (BHF 2012). In a study conducted by the National Child Measurement Programme in 2012, it was ascertained that an estimated 33.9% of all children between 10 and 11 years of age in England are overweight (BHF 2012). When parents find it less important to define what their children should eat or what they should not, it becomes a pivotal issue as to how much parents determine the state of their children’s health. According to Kellow (2012), one in every ten parents in the UK raises concerns about their children’s low body weight. Conversely, about 33% of mother and 57% of fathers considered the weight of their children as normal when such children were actually obese (Stamatakis et al. 2010; Ferry 2013). Whereas the majority of parents in the UK are too busy to plan healthy diet for their children, 73% do not care what their children watch or eat outside the home (Kellow 2012). In contrast, few parents encourage their children to take regular exercise while others are less concerned with the eating behavior of children during school hours. As a result, nine in every ten children indulge in junk food with high calories, high fat and sugar content but little vitamins or minerals as noted by Ferry (2013). The unfortunate fact is that parents in the UK are becoming used to the picture and there is little effort to address that issue yet obesity costs the country over  £2 billion every year in addition to reducing victim’s life by 9 years (BHF 2012). The importance of conducting this research revolves around the fact that lifestyle diseases are the leading cause of deaths globally. Unfortunately, children are

Crime in America Essay Example for Free

Crime in America Essay Crime statistics tells us the variation of crimes that are being committed in the United States. The Bureau of Statistics compiles information processed in the federal justice system and gives us statistics on the many different crimes in America. This is a site that compiles crimes and tells us about how many different crimes are being committed and how many times they are being committed. This also gives us an idea of how much space we need to house these criminals. There are many jails and prisons that are over populated. Statistics also tell us that our crime fighting is not as good as it should be. With the websites for crime reporting this helps us to see what crimes are being committed and, how we can prepare for this and, how to prevent it. There is not a way to stop all crime or even prevent it but if we know what crimes are being committed more it will help us get a better understanding on how to catch the criminals that are involved in this type of behavior. In my honest opinion no crime is ever going to be completely stopped. If we all work together to pinpoint the main crimes we may also be more prepared to deal with them and catch the individuals involved. Crime in America today is on the rise the question is how to fix it before it gets out of hand. There are many different crime reporting measuring systems today. These help us get an idea of what crimes are being committed the most in what areas. With these types of statistics we may be able to start fighting crime in these areas to prevent further destruction in our communities. The Nation’s two crime measures are the UCR program and the NCVS. The UCR (Uniform Crime Reporting) this program collects information on crimes reported to law enforcement agencies. It compiles data monthly from the state agencies that report to the FBI. This system examines each report for accuracy or errors that may have occurred. It compares each monthly report to previous months and years to determine how much crime was committed from each month to each year. It gives us a detailed annual report. This comes in handy when trying to figure out if crime is on the rise or it is decreasing. The NCVS (National Crime Victimization Survey) this program gives us a detailed picture of crime incidents, victims and trends. This is used to uncover crime, update the survey methods and broaden the scope of crimes measured. The survey is designed to collect detailed information on the frequency and nature of the crimes that are being committed. This helps us to determine how many times this crime is committed and how it is being committed. It does over 43,000 personal household interviews twice a year. They rotate new houses every couple of years to make sure that it remains as accurate as possible. It also estimates crimes that have been reported and those that have not been reported. It also summarizes the reasons that individuals give for reporting or not reporting the crime. These programs share many similarities and differences. The similarities that they have are that they both measure crimes. The way that they measure crimes are very different from one another. But they both hope to achieve the same things. How they differ the most is in what they do. The UCR is designed to gather information and determine the statistics of the crimes reported by the law enforcement officers. The NCVS was designed to provide information about crimes that used to be unavailable. Also the two crime programs are different in other ways a well. One may judge crime by the size of the household, why the other judge’s crime by the number of crimes divided by so many people in that area. So as you can see even though they are out to achieve the same thing they just do it in different ways. It is hard to tell if the public’s perception of crime has changed over time. American’s perception of crime may be influenced by their assessments of how things are going in the country today. They also perceive it to be on how the country is economically. If America has a higher amount of jobs the crime rate may go down. When jobs are low and there is no work the crime rate may go up. Looking at the amount of crimes committed each year can also determine the public’s perception from one year to another. If they see more crimes in the last two years then they did in the previous years they are going to see that crime is on the high. I think that the future of crime depends on the economy. It also depends on how much crime is reported, and how people relate the experience of their crimes. If crimes are not being reported it is hard to figure out what types of crimes are being committed. It is hard for me to predict the future of crime because each criminal and each crime is different. If there were more people in America that would work as a whole to keep their community as safe as possible, I don’t think that crime would be big in that particular community. Also there are crimes today that are being committed due to lack of jobs. Most people will do what they have to, to make sure that their families are being taken care. A lot of problems today in my opinion depend on job security. If more people could have jobs then I don’t think that there would be as many crimes being committed. The American crime rate in my opinion just depends on the economy and the people in the economy. If you want to make a difference you will. If you don’t then you will be part of the problem not the solution.

A Mesophilic Origin of Life Essay -- Biology Essays Research Papers

A Mesophilic Origin of Life Nearly all scientists agree that life on Earth began billions of years ago. Most will also agree that RNA appeared first and found a way to replicate itself, an essential step in the early stages of life. Without this ability of RNA, only short pieces of DNA could be copied and no enzymes could be created to copy longer strands which would be necessary for the formation of enzymes[1]. Beyond that, there is very little agreement about the origin of life, including what the original ancestor of all life was like. This has led to a significant amount of debating with very few answers. Scientists are still debating how life originated: was it a series of successive steps or a spontaneous gathering of the necessary materials? The problem with the second theory is that the odds of this happening are about the same as a tornado assembling a 747 aircraft in a junkyard.[2] As of now, we still have to ponder whether the ancestor of all life, or LUCA, was a single being or a community of organisms sharing genes. Another question entails whether the last universal common ancestor (LUCA) dwelled in a hot-water environment or a cooler place, possibly near the surface of the ocean. The experts are split almost evenly on this question and both sides present convincing evidence for their side of the argument, but we will focus primarily on the side that believes that LUCA was not thermophilic, and, in fact, lived in a cooler surrounding. This cooler surrounding would have likely been near the surface of the ocean rather than in the vicinity of a thermal vent near the ocean’s floor. The other side argues that Earth was warmer 3.5 billion years ago, when life is believed to have been spawned. This, c... ...more evidence, especially in RNA sequences, until an answer can be established. 1] Smith, Szathmary 1999 [2] DeDuve, 1991 [3] Whitfield, 2004 [4] Levy, Miller, 1998 [5] Vogel, 1999 [6] Brochier, Phillippe, 2002 Works Cited Brochier, C., and H.

Physiognomy Theory Essay

Physiognomy also known as the Arts and Sciences of the face, dates back to Aristotle’s era. This philosophy was first used by the Greek and spread to places as far as Asia and the Middle East within a short period of time. It became very popular especially in Asia, where people would use this to determine people’s suitability for jobs and important government positions. The number of important people such as Emperors, successful professionals and government officials that believed in this theory also helped the rapid spread of physiognomy throughout the continents. Back then, most people were convinced that this so called science could not only determine their personality as well as their fate but also help them make better choices in life. Physiognomy claims that an individual’s character, destiny and the ability to perform certain tasks in life, can be defined by studying his facial features. Studies done throughout time have failed to back up this theory, conf irming that physiognomy is just another pseudoscience. Physiognomy and its uses and definition have changed overtime according to people’s needs. Figuring out the traits and behavioral trends of people was not enough; so physiognomy experts then argued that people’s characteristics had a connection with the signs of the zodiac. As the numbers of followers of Physiognomy grew, so did the demand for physiognomists, or face readers as they were called, turning this philosophy into a profitable worldwide business. After many years, physiognomy was revived and it is now used and believed to work efficiently to determine criminal tendencies in people. Physiognomy became more credible to people, when a U.S. judge backed up the theory after observing the facial features of those that appeared in his court. Physiognomy, is the study of facial features that allows philosophers to determine an individual’s traits and flaws. This theory supposedly ascertains different factors in someone’s life, such as moral values, self control, social and criminal tendencies. People’s abilities are also things that are supposedly defined by reading the facial aspects of an individual. It is also believed that this theory predicts the fate of people by studying certain parts of the face as the eyes, mouth and nose . Skin color, hair type, voice, forehead lines and certain body parts are considered when evaluating an individual. The shape of someone’s skull, or the way that the soft tissue sits on it, can also say something about the character and true identity of the person being evaluated. The theory of physiognomy has been tested many times since its discovery, thousands of years ago. However, none of the experiments done to prove it have been successful. The deficiency of scientific evidence to verify the theory, is the reason why physiognomy is considered a philosophy rather than science. Most studies done by advocates of this philosophy, have and still do lack an explanation of how and why the theory works. Supporters of physiognomy have taken advantage of certain circumstances in which someone’s facial traits help determine a condition. Some genetic diseases for example have specific facial features which help diagnose the illness. Down’s syndrome and DeLange syndrome are good examples of these diseases. Supporters of this theory often compare these diseases to physiognomy as a way to prove the theory. Just like Down’s syndrome and Delange syndrome are used as evidence of this pseudo- science, so are many other similar conditions. The studies done by non-advocates of this theory have proved that a person’s character and behavior cannot be defined by examining the facial features. Studies have shown that a relation between facial traits and someone’s personality does not exist. There are many factors that are scientifically proven to have influence over the development of an individual’s personality and temperament during their lifetime. Several studies with people of all ages and from different backgrounds have stated various reasons that in the long run shape someone’s character. The way that a child is raised, his parents’ traits and flaws and the people that he is surrounded by have an impact on personality. Culture and different ethnic backgrounds are also factors that have an effect on someone’s personality and the person that they grow up to be later on in life. Personal experiences and certain events with emotional value for a person are among the causes that influence an individual’s character, mentality, social and emotional life.
