Homeostasis - Essay Example The failure of the organs to excrete waste products is very detrimental to the health of a person and could possibly lead to death. Diseases are likewise outcomes of this failure. There are natural bodily processes like Osmoregulation which creates balance thus preventing the occurrence of diseases relating to the excretory organs. There are also man-made treatments to combat the negative effects of the malfunction of the excretory systems like Dialysis for severe kidney diseases. We shall concentrate on the two excretory organs: the kidneys as a component of the urinary system and the skin as a regulator of temperature. In the course of the discussion of the structures and functions of the urinary system and the skin, the effects of the failure of these systems will be tackled. The terms Osmoregulation and Dialysis will likewise be elaborated and explained. The urinary system has four major components: the kidneys, the ureters, the urinary bladder and the urethra. The main organs of the urinary system are the kidneys. The kidneys with its functional components called nephrons, form the urine. The process begins during blood circulation. Blood contains Urea, which is produced when protein-rich foods are broken down. Blood through the bloodstream travels through the kidneys and deposits the urea there along with water and other waste matters. This results to the formation of urine. The ureters are small tubes where urine passes through going to the bladder. Urine is then stored in the urinary bladder. The bladder sends information if there is a need for urination when the bladder is filled up. The contractions of the muscles in the bladder release the urine into a tube called urethra. The urethra is the last passageway which allows the body to release urine or to undergo the process of urination. The primary function of the urinary system is to get rid of waste products in the body resulting from cellular metabolism. This function preserves the normal composition and volume of body fluids. Aside from maintaining the appropriate amount of water in the body, the urinary system also has other functions. It sustains the normal pH of the blood and helps in managing the proper production of red blood cells by secreting the erythropoietin hormone. By producing the renin enzyme, the urinary system likewise helps in the maintenance of normal blood pressure. What will happen if the major components of the urinary system fail It will lead to major health problems. Diseases or disorders resulting from the urinary system failure include Kidney Stones which vary in size and may cause little or great pain, and Renal Failure of the kidneys which is a result of the kidneys not being able to properly and completely remove waste products from the blood. In this case, the kidneys are also not able to regulate the chemicals and water in the body. Other disorders are the Urinary Tract Infections which are caused by urinary tract bacteria, Urinary Incontinence, or the inability to control the bladder in releasing urine, and Urinary Retention, or problems in emptying the bladder (Your Urinary System and How It

The Mixing of Cultures Essay Example for Free

The Mixing of Cultures Essay Pepee,Joseph, The White Women of Genesee. The World Turned Upside Down. Boston: Bedford, 1994. Occum,Sampson, A Short Narrative of My Life. The World Turned Upside Down. Boston: Bedford, 1994 The World Turned Upside Down Chapt. 2. Boston: Bedford, 1994. In early America as the Europeans began to colonize the land, most Europeans did not think too kindly of these very different brown people that already inhabited this space. The European thought leaned greatly towards the idea of the Native Indians being of a barbaric and heathenness culture that must be changed (converted and educated) or eliminated, however, the exchange of culture frequently went both ways and sometimes those very differences in culture proved to be a great seduction to the non-Indian people. Some European immigrants found a great appeal to the Indian way of life by embracing the Native American way of; speaking, eating, dressing, hunting, farming etc. Others went on their own free will to go live with the Indians. Marrying and adopting outsiders was customary to some Indian traditions and with the rise of neighbors that were not Indian, the natives sought to intermarry due to population losses. Children from these marriages often became mediators in dealings between the European and Indian cultures. The story of Mary Jemison reflects that mixing of cultures and the affinity that can develop to the Native way of life. She was taken captive by the Indians at fifteen years old then adopted into a loving Indian family. As the years went by she adapted and grew to love her Indian family and friends. She married an Indian and considered herself one of them. Mary Jemison was one of many captives who eventually refused the opportunity to come home, finding life in Indian society more rewarding. Many people- then and today- have an attraction to the Indian culture for the very differences that the Europeans sought to destroy them. Those differences seemingly so unique and different from our culture; and though the European culture from a distance won the battle of incorporating their way of life into a new nation and an eventual political superpower, the native culture did leave a humble cogitation on America as it emerged.

Essay on theories and models of health promotion

Essay on theories and models of health promotion The word health came from the old English word for heal (hael) which means whole, indicating that health concerns the whole person and their integrity, soundness, or well-being (Crafter 1997). Health can be defined as a state of well-being, interpreted by the World Health Organisation as a state of complete physical, mental and social well-being, not merely the absence of disease or infirmity (WHO 1946). Health promotion (HP) is the process of enabling people to increase control over and to improve their health. HP is a positive concept emphasizing social and personal resources as well as physical capacities. WHO (1984) In this assignment I will discuss health, HP principles, changing peoples behaviour and attitudes and I will also apply the application of a HP strategy (Beatties model). Beattie (1991) identifies three areas, health persuasion, personal counselling and community development. It also incorporates the knowledge, attitudes and beliefs (KAB model) which helps to support Beaties theories. His model offers a structural analysis of HP approaches. This model involves advice and information that is evidence based, insuring that the correct information is available to the client so she can make an informed choice, as the Nursing and Midwifery council (NMC 2008) stipulates. The KAB model, when applied, concentrates on what makes a person want to change. Dahlgren and Whitehead (1991) discuss the layers of influence on health and its social and ecological theory. They also attempted to link the relationship between the individual, their environment and disease. Individual people are at the centre, with a set of fixed genes. Surrounding them are influences on health that can be changed or modified. The first layer is personal behaviour and ways of living that can promote or damage health. e.g. ones choice to drink alcohol. Individuals are often affected by friendship patterns and their communities. The next layer of Dahlgren and Whiteheads theory is social and community influences, which provide mutual support for members of the community in unfavourable conditions. But they can also provide no support or have a negative effect. The third layer includes structural factors such as housing, working conditions, access to services and provision of essential facilities. Festinger (1957) used the term cognitive dissonance to describe a persons mental state when new information is given. This prompts the person either to reject the new information (as unreliable or inappropriate) or to adapt attitudes and behaviour, which could fit with it. Bradshaws needs also plays a critical role in HP. The schedule of antenatal care is dominated by a medical model. When providing care, the needs of women must be heard and incorporated into their care. Bradshaws needs can be used by midwives and other professionals to identify womens needs in pregnancy. This can lead to the type of healthcare which is more likely to address the social determinants of health and improve health outcomes for pregnant women. Normative Need: As defined by an expert, to be a need that all require. Such as the advised number of antenatal visits. Felt Need: an individual or groups own personal need. Expressed Need: A felt need which turns into an expression for help Comparative need: Comparing the needs of different groups and finding a common occurance. Bradshaws concept has four different types of need: My HP strategy focuses on Bradshaws comparative need. To educate women of 30yrs+ to abstain from alcohol during pregnancy. This is evidence based on research showing the link between alcohol and FAS. HP is a key part of the midwifes role. However, the effectiveness of its practice is often not easily recognisable. The document, Saving Lives-our healthier nation, (DOH 1999), suggests that individuals are not solely responsible for their own ill health. Health professionals i.e. Midwife and the government all play an important part in working towards achieving health for all and reducing inequalities in health and health care provision. The report also states that Healthcare authorities and primary care groups have a responsibility towards public health. (DOH 1999) The Royal College of Midwives (RCM 2000) suggests that maternity care is not just a delivery service. Midwives make a major contribution to family well-being and the wider public health and its contribution is yet to reach its full potential. HP is often used to describe behaviour or actions, which directly or indirectly influence the health of others. This may include preventing ill health, maintaining positive health, raising public awareness of health issues, protecting the public from harm, educating people to make healthy lifestyle choices and reducing inequalities in health and provision of healthcare (Dunkley 2000). HP within midwifery, involves enhancing positive health and reducing the risk of ill health through education. For expectant mothers it is a time of immense psychological and physiological development. During this time the woman acquires a great deal of new and sometimes confusing information from family, friends, magazines and health professionals. Midwifes have a duty of care to inform women about health damaging behaviour where this may occur. They also have a duty to encourage discussion on such topics i.e. alcohol in pregnancy, nutrition and choices of feeding. Following articles written in the Guardian and Telegraph newspaper in February 2010 stating that the Department of Health advice is that women should not drink at all when trying to conceive or when pregnant, but if women do chose to drink they should not have more than one or two units once or twice a week and not drink enough to feel drunk is what inspired my decision to look at Alcohol in pregnancy for this HP. The National Institute on Alcohol and alcoholism (NIAA) clearly states that NO alcohol should be consumed in pregnancy. The Telegraph newspaper in January 2009 reported that OLeary (an Australian scientist) states Women who drink five small glasses of wine during the course of a week in the first three months of pregnancy increase their risk of a premature birth by 70 per cent, even if they stop later. Research from the Infant feeding survey 2005 shows that drinking alcohol socially when pregnant has a higher occurrence in women in the 30-35 year age range and above. The Royal College of Obstetricians and gynaecologists (RCOG) 29th June 2010 stating there is no evidence that a couple of units of alcohol once or twice a week will harm an unborn baby. These contradicting reports led me to research the need for a HP on alcohol consumption in pregnancy. Professor Phillip Steer of the RCOG believes that if women ate and drank a more healthy diet this would result in healthier babies thus a healthier nation. Another specialist, Dr Raja Mukherjee, consultant psychiatrist and expert in foetal alcohol syndrome, stated that if a wealthier woman who has previously consumed wine on a regular basis, continues into her pregnancy, she is in the high risk group. He reports that they are actually putting their babies at risk before they even know they are pregnant, in some cases. Mukherjee (NOFAS) also reported that one of the most severely affected children he has seen, was born after a wealthy woman continued to consume half a bottle of wine 2 to 3 times a week. In my HP plan I wanted to target women in the older age ranges. Using the media to publicise the damage caused by alcohol consumption in pregnancy. My idea constituted a run of billboard posters depicting babies being forced to consume alcohol as well as television advertising. The adverts would be hard hitting with a simple dont drink slogan. The campaign would be called the you drink, I drink campaign. The primary aim would be to stop women drinking alcohol in pregnancy. The secondary aim would be to at least educate and inform women of the concerns related to drinking alcohol. Both aims would hope to have an effect in reducing the cases of fetal alcohol syndrome, currently 1:100, (NOFAS 2010), caused by drinking alcohol in pregnancy. Models have been used in HP for some time, but can they be a part of midwifery? It could be claimed that the unique and individual situations of pregnancy and birth do not lend themselves to categorising women and their needs. Every woman and every pregnancy is different. Could it be possible to apply a standard package of professional care? If midwifery is viewed as a health-promoting activity, then it may be that HP models and approaches can enhance the way that midwives deliver care by developing an agreed research-based framework, which, rather than labelling women, standardize good practice (Crafter 1997). The NHS plan, (NHS 2000), which seeks to develop an NHS that is patient-centred and fit for the 21st. Century, suggests that the role of the midwife should be developed in public health and family well being. Whilst researching my strategy I found that the first reported association between maternal alcoholism and a characteristic pattern of cranio-facial, limb and cardiovascular defects in the offspring was published in The Lancet Saturday 9 June 1973. Since then the results of a large body of research have been published. This is clearly an indication that a new HP aimed at pregnant women is needed! In 1996 the RCOG published a guideline on alcohol consumption in pregnancy. They wrote that there was no conclusive evidence of effects in either growth or IQ at levels of consumption below 120 gms per week. Nonetheless, they recommended that women should be careful about alcohol consumption in pregnancy and limit this to no more than one standard drink (8 gms of alcohol) per day. This disagrees with the recommendations from NICE. Who state that if a woman does decide to drink alcohol, she should drink No more than one or two units, once or twice a week. It is clear that the consumption of alcohol during pregnancy cannot be deemed without risk, however, controversy continues as to whether there is any safe level which women should be advised not to exceed. According to The National Organisation on Fetal Alcohol Syndrome (NOFAS), the medical and scientific literature overwhelmingly supports the hypothesis that there are risks of alcohol related brain damage from drinking low to moderate amounts of alcohol during pregnancy.   Based on these findings, NOFAS position is that there is no safe time, no safe amount, and no safe alcohol during pregnancy. (NOFAS 2007) The obvious way forward is to re-educate women through HP. There are key drivers in health matters such as the National institute of clinical excellence (NICE) and the Acheson Report for the Department of Health, which was a report to contribute to the development of the Governments strategy for health and an agenda for action on inequalities in the longer term. The publication in February 1998 of the consultation paper Our Healthier Nation; a Contract for Health was an important landmark. It identified the need to improve the health of the worst off in society and to narrow the health gap as an overriding principle. (DOH 1998) The report took into account the main features of Our Healthier Nation as they affect inequalities. It discussed tackling inequalities in the settings of schools, the workplace and neighbourhoods. The section on the NHS included an element on the reduction of inequalities through local partnerships taking into account plans for Health Improvement Programmes and Health Action Zones. It also takes into account the changes outlined in the White Paper The New NHS: Modern and Dependable. Whilst developing my HP strategy I looked for current Local and National strategies. The key strategy is that of the National Organisation on Fetal Alcohol Syndrome (NOFAS). They offer an extensive service, including conferences, support group meetings, publications and in particular the Baby Bundle Project. The training for Midwives Project is an initiative of NOFAS-UK to provide useful and positive health information about the consumption of alcohol in pregnancy. Midwives play an important role and can help prevent FASD. Another key strategy is Drinkaware. Drinkaware aims to change the UKs drinking habits for the better. They promote responsible drinking and find innovative ways to challenge the national drinking culture to help reduce alcohol misuse and minimise alcohol-related harm. They are an independent, UK-wide charity, who are supported by voluntary donations from across the drinks industry to equip people with the knowledge they need to make decisions about how much they drink. Drinaware also helps tackle alcohol misuse. As well as working with other organisations and individuals across the UK to fulfil the educational, community and awareness campaigning function envisaged in the Governments Alcohol Harm Reduction Strategy. They also provide easily accessible, evidence-based information about alcohol and its effects, to employers, young people, teachers, parents and community workers, such as Midwives. They use a range of advertising mediums, such as film, multimedia and TV. Another National strategy is NICE. Their current recommendations on alcohol in pregnancy is that Pregnant women and women planning a pregnancy should be advised to avoid drinking alcohol in the first 3 months of pregnancy if possible, because it may be associated with an increased risk of miscarriage. But as previously discussed they also advise that women planning a pregnancy or in the first 3 months should not drink at all. The negative theory of this is that the government is presuming that all women will know what 8g of alcohol is, or 1.5 units. Should the government be advising women in a more user friendly way? The HP strategy advising women what they should or should not do will fail as not all women will know how much is too much. This creates a concerning risk. The government need to re-address the strategy to be usable by midwives and pregnant women alike. They should be re-thinking ways to educate women as to what a measure of alcohol is. Nice is also adding to the confusion in saying avoid alcohol then expressing that it can be drunk but in moderation. This sends a very confusing message to health promoters and pregnant women. According to NICE it is the responsibility of the midwife to educate their clients in the safe levels of alcohol consumption at their first meeting. At the expectant mothers first visit to the antenatal clinic the midwife should explain how the pregnant woman will be monitored with regular examinations and tests to ensure that the pregnancy is progressing normally. It should also be emphasised that the womans health inevitably influences that of the fetus and can have major impact on health in childhood and later life. Midwives need to advise their clients on what is safe. Would it be safer and clearer to advise all women, all of the time, not to drink alcohol at all? But the midwife would then not be offering the woman informed choice. It is the role of the midwife to offer lifestyle advice and to tell women of the implications of what alcohol consumption can do to a fetus. Then as Beatties model states, its the clients prerogative to choose what their actions are but it is the midwives role to try to encourage a change in previous unhealthy behaviour. During the development of my HP strategy i gained a peer review. (See appendix A). The positive feedback was tremendous. Confirming that I had correctly assessed the need for the target audience to be women aged 30-35 years+ and that a hard hitting advertising campaign was the right route to take. It highlighted the need to define which health models i would use and I decided on Beatties and KAB rather than Tannahill, which is another well know model. Although I did realise the need to decide on a primary and secondary aim for my promotion. The review also highlighted the need to be able to assess the success of this strategy. This would be easily measured by seeing a reduction in babies born with FAS. During antenatal care Midwives impart relevant information in a teaching way, but it is of no value if that teaching is facilitated in a lecturing style. Women wont learn if spoken at. It is not possible to provide an exhaustive coverage of pregnancy, labour, and the postnatal period during a set of 3/4 classes. A childbirth educator can boost her clients self esteem by valuing everyones comments and creating an atmosphere in which learning is a shared experience. The aim of childbirth education, therefore should be to help the women understand the importance (for their mental health) of getting the information they need, and to empower them to ask questions when and of whoever they want. It has been clearly demonstrated that a womans mental health after delivery has been closely linked to the amount of information she received during her labour (Oakley 1980). Health promoters are not always effective at providing information. Hillan (1992) suggests many women feel that there are a variety of ways during an antenatal class to empower women to ask questions of their caregivers. Women can be empowered by the attitude of their teacher. In Beattie (1991) Strategies for HP, he incorporates empowerment as an important aspect of his model to empower individuals to have the skills and confidence to take more control over their health. Analyses of empowerment shows there is a need to distinguish between self-empowerment and community empowerment. Self empowerment is used to describe HP strategies which are based on counselling and which use non-directive, client centred approaches aimed at increasing peoples control over their lives. Midwives frequently engage in client-centred work, as they are concerned with facilitating client autonomy. The client sets the agenda and the health professionals role is facilitating, guiding, supporting and empoweri ng the client to make informed choices (Dunkley 2000). Community empowerment is used to describe a way of working which increases peoples power to change their social reality. It is also a way of working which seeks to create active participating communities who are empowered and able to challenge and change the world about them. This approach helps people identify their own concerns and gain the skills and confidence to act upon them. It is unique as a bottom-up strategy and calls for the different skills from the health promoter (Kendall 1998). The midwife, becomes a facilitator whose role is to act as a catalyst. Carl Rogers has also developed the theory of facilitative learning. The basic premise of this theory is that learning will occur by the educator (in this case, the Midwife) acting as a facilitator, thus establishing an atmosphere in which learners feel comfortable to consider new ideas and are not threatened by external factors. When teaching adults we must be aware of their different learning styles. Adult learners are a very diverse group. Andragogy (the teaching and learning of adults) was first developed by Alexander Knapp in 1833. Then in 1984 Knowles used Knapps theory and expanded on it. Knowles emphasizes that adults are self-directed and expect to take responsibility for decisions. Adult learning programs must accommodate this fundamental aspect. Knowles himself changed his position on whether andragogy really applied only to adults and came to believe that pedagogy-andragogy represents a continuum ranging from teacher-directed to student-directed learning and that both approaches are appropriate with children and adults, depending on the situation. (Knowles 1984) Beattie offers a structural analysis of the HP approaches. He suggests that there are four paradigms for HP. These are generated from the dimensions of mode of intervention which ranges from authoritative (top-down and expert-led) to negotiated (bottom-up and valuing individual autonomy). Most HP work involving advice and information is determined and led by practitioners, or midwives in this case. The work and thoughts of Carl Rogers in the 1960s have been formative in understanding the importance of self-awareness and the experiential learning in helping individuals to understand and make decision. It is therefore important before commencing adult education to examine the structure of the model and look at whom it is aimed at. It is important when working within a team that certain values are shared and made explicit so that the carers can work towards the same goals and the recipients of care can be clear about the standards and outcomes to expect. Developing and working with unified models and approaches in health promotion and midwifery can therefore help midwives to communicate with each other more effectively and strengthen initiatives, which benefit everyone (Crafter 1997). The transition to parenthood is an emotional time for both the pregnant woman and her partner. The shift from marriage or partnership to the first pregnancy is a major transition point in a womens life. It is also the time that HP can have its biggest effect. Women are open to learning new things and hearing from many different sources about whats best for them during this time. A number of studies have suggested and therefore confirm this theory that the most difficult transition for couples to make is the birth of the first child (Cowan Cowan, 1992). All major transitions involve making changes and a period of disequilibrium. A professional career woman may find the whole process out of her control and be left reeling. Motherhood can significantly challenge a womans sense of identity, revealing a tension between personhood and parenthood. Antenatal classes, media, books etc all play a part in acclimatising the woman to her new role. Other outside influences are the social surroundings. Pregnant women from lower or working classes may not feel they have the same support as those from middle or upper class social areas. They may not reach out to areas of support, including what we consider basic antenatal care. Younger mothers may look at parenthood through rose tinted spectacles, imagining their baby will sleep through the night. While the more mature first time mother is more realistic in her outlook. This is where HP again plays an integral part in educating the woman through sources of media, care and through learning in the community. Expectations and theories have changed greatly over the last 40 years. Older mothers are more common as are teenage mothers. Teenage mothers in the 1960s were sent away to discreetly have their babies, now they are a common part of the community with different needs to that of the older mother. HP has to be aimed at all groups all of the time. It is up to the care giver to facilitate this information at the right level for each individual case. Good quality teaching, support and HPs received well, all contribute to the transition to parenthood, thus increasing the confidence of the new parent. After all, it is one of the most vulnerable times in their life. With successful antenatal learning in place this would then enhance the transition to parenthood and that of attachment. Bowlby (1969) devoted extensive research to the concept of attachment, describing it as a lasting psychological connectedness between human beings Proximity Maintenance The desire to be near the people we are attached to. Safe Haven Returning to the attachment figure for comfort and safety in the face of a fear or threat. Secure Base The attachment figure acts as a base of security from which the child can explore the surrounding environment. Separation Distress Anxiety that occurs in the absence of the attachment figure. Bowlby (1969)Bowlby believed that there are four distinguishing characteristics of attachment: These characteristics are learned as children and are what we use when moving from childhood to parenthood. Without a good base we cannot expect new parents to successfully proceed into parenthood without some re-education and the support of quality care givers. In conclusion, the RCM Vision 2000 describes the midwife as a public health practitioner. Midwives have always enhanced, facilitated and supported factors, which promote physical health, psychological, social and spiritual well being for the woman and her immediate family. Some of the key points that should be considered for the future of midwifery HP practice, is that it needs to be clearly defined, national and political recognition of the midwives contribution to public health should be improved and midwives should promote health within the socio-culteral and economic context of how individuals live their everyday lives (Dunkley 2000). Providing antenatal care to woman and fetus demonstrates a unique opportunity to enhance holistic health through advice, guidance, support and social networks where the woman can be offered further specialised care if needed. This assignment has discussed the concept of health and HP, the value of alcohol avoidance and briefly the effects on the pre gnant woman. Beatties and KAB model was used to show the importance that a supportive environment is created in which people can challenge ideas and question beliefs. Beatties model is adaptable and could be applied to many scenarios, the model shows a knowledge of awareness of adult education by provoking a deep understanding of processes and problem solving, and therefore the quality of teaching and the learning process. There are a number of ethical issues involved in parent education. Participants need to be listened to carefully and their questions answered truthfully, which gives a positive effect on the woman and leads to the skills and confidence to take more control over their health.

Sadruddin Jiwani HIV/AIDS Introduction: HIV stands for Human Immunodeficiency Virus. It is a disease of the human immune system, which is caused by infection with human immunodeficiency virus. To understand it in a better way, let us break it down: H - Human - This specific virus can only infect human beings. I - Immunodeficiency - It weakens the immune system of the body by destroying important cells that fight disease and infection. A â€Å"deficient† immune system cannot protect you. V - Virus - A virus can only reproduce itself by taking over a cell in the body of its host. HIV is similar to other viruses like the common cold or the "flu". The main difference between the other viruses and HIV is that, the immune system can clear most viruses out of the human body, but it is not case with HIV. The human immune system cannot eradicate it, since the target of this virus is the immune system itself. Researchers are being conducted to figure out the reason for it. An infected person may experience a brief period of influenza-like disability, during the starting phase, followed by a prolonged period without any syndrome. As the disability progresses, it deteriorates the immune system more and more, making it more prone to get diseases, such as tumors and opportunistic infections which may prove to be fatal to the infected person. AIDS stands for Acquired Immunodeficiency Syndrome Let us break it down, to understand it in a better way: A - Acquired - AIDS is not inherited from the ancestors. It is acquired after birth. I - Immune - All the ... ...ld Health Organization (WHO) report shows that, most people living with HIV or at risk for HIV do not have access to treatment, care and prevention and there is still no cure. In spite of these challenges, there have been successes. Global efforts have been made to address the epidemic, specifically in the last decade. The HIV prevalence rates have been reduced in a small but growing number of countries due to prevention and new HIV infections are believed to be on the decline. In addition to this, the number of people with HIV receiving treatment in resource poor countries has increased 10 times since 2002, nearing an estimated 4 million by 2008. In U.S, not every healthcare provider is equipped to provide specialty care to people living with HIV. But if a provider cannot provide treatment for your HIV disease, the same person should refer you to someone who can.

The Amateur Scientist :: essays research papers

I was on my way to work, when I started to read this interesting story and I don't deny that I was a little sceptical in the beginning. But the more I read, the more I wanted to know about this man and his unique ways to define Science. I finished reading it in about 15 minutes, it literally sucked me in. This is an attempt to analyze and explain to the "audience," what my personal point of view is regarding this great genius, great mind, great scientist Richard Feynman. Defined by his colleagues as the "The brightest mind since Einstein," he explains how he used everyday tools to make scientific discoveries. How he describes his methods in a simple way makes science enjoyable and understandable, even to the average reader. I enjoyed reading the essay entitled "The Amateur Scientist," by Nobel prize-winning physicist Richard Feynman (1918-1988). I found it to be very interesting and felt that Mr. Feynman was very thoughtful. Rather than explain in technical detail about his work in physics, Feynman instead related interesting anecdotes throughout his life, as a college student and graduate student at Princeton University, that gave to the reader an understanding of his work as a scientist. The writing won my attention because his stories about his youth and his days at Princeton fascinated me. He was always exploring his environment to learn new things about science, especially how things worked. Feynman's thirst for clever things to do and clever ways to do ordinary things were remarkable. One of the best anecdotes that illustrate this point, was his experience at Princeton detailing ants' behavior. Feynman was constantly searching for the connection between hypothesis and truth, so one day at Princeton he started to observe the ants' that were coming out on his windowsill. The experiment with the ants is a reflection of this man's mind, always in search for an answer. In this anecdote Feynman explains how, with only a bit of sugar, and a couple of pieces of paper, he was able to find out many things about ants' behaviors. Feynman compares his study on the ants with the same kind of "experiment" he performed in Brazil, observing leaf-cutting ants. The author pointed out that, although the Brazilian ants seemed to be smarter, there are still some affinities with domestic ants. It is remarkable how Feynman discovered that ants have no sense of "geometry," the goal of his experiment was to determine whether or not ants have some kind of communication a nd if they have the ability to find their way back where the "food" was.
