...Chemistry in Society CHM/110 July 23, 2012 Chemistry in Society The differences between accuracy and precision “In the field of science accuracy is the form of measurement that calculates the degree of closeness of a quality to its true value. Precision is a unit of measurement that is also referred as the ability to reproduce the same results multiple times” (Taylor, 1997). The differences are within the description, it all depends on what you are looking for within the results of a test for the proper use of these two units of measurements. Society depends upon the accuracy and precision of measurements for products sold by the retail industry Today’s society depends on the accuracy and precision of measurements for products sold by the retail industry, such as a gallon of gasoline, the weight of potato’s , or a gallon of oil. These measurements have to be precise and accurate when it relates to how farmers sell their products such as tomatoes, soybeans, milk, peanuts, and cotton, by weight and or in a bulk sale. Like food products gasoline, water, oil, and several other liquid goods sold in quantity and if the measurements not accurately sold per gallon, then the United States government will not retain a profit from the barrel of oil, water, E-85, and several other liquid goods that purchased from other countries. I would have to say that this really is about supply and demand and the ability to generate a profit from the accuracy and precision of the weight...

...CHEMISTRY IN LIFE Charles Barker CHM/110 7/6/2015 Subhashis Nandy Introduction When living in a world such as ours, chemistry plays a large role in how society interacts. Chemistry can be viewed from many different angles because of its dynamics when dealing with the nouns of life (People, places, and things). With people, chemistry is how he or she connects to their social conformity. With places, chemistry is the structure and atmosphere that brings about the culture to the arena. With things, chemistry is the accuracy and measurement that brings the degree of closeness to the true value of its quality. In this paper, one will cover chemistry in terms of accuracy and precision, the relation to scientific methods, and how these methods can be applied to present and future lifestyle. Accuracy and Precision Accuracy and precision are close in comparison. In the field of chemistry and science, the difference of the two is that accuracy is the closeness of one or more measurements are to the correct answer. Precision on the other hand is the closeness of measurement to one another. It can also be referred to as the ability to recreate the same or similar results many times over. The differences of the two are within their meanings. The dependency of the situation will lie within the results of the diagnostics ran for the proper use of the two units of measurements. Explain how society depends on the accuracy and precision of measurements for products sold...

...Antoine-Laurent Lavoisier Antoine Lavoisier known as the “Father of Modern Chemistry,” a French noblemen who made influential contributions to the world of both Biology and Chemistry. Lavoisier was a natural philosopher in the late 18th century, this was during the Chemical Revolution. He played a role in the conversion of Chemistry from a qualitative to a quantitative science. Some of his many contributions to Science include; the first chemistry book, extensive list of elements and naming Hydrogen, Oxygen and Carbon. Lavoisier made a vast mark on the world of Science resulting in advancements in better understanding the natural world. Lavoisier was born in Paris, France on August 26, 1743 to a wealthy Paris family. His father Jean-Antoine Lavoisier, was a Parisian lawyer in the Paris Parliament. He was married to Émilie Punctis, the daughter of an affluent family due to their butchery business. His mother died at the age of 5 and left him a large amount of riches. Through the ages 11 and 18 he attended school at Marzarin College, here he studied the general subjects. During his final two years he studied the sciences in depth, his interest in science was encouraged by geologist Jean-Étienne Guettard. This was a professor whom he had gotten close to, later on he would go on to collaborate with on a geological survey. Lavoisier was always interested in Science and Mathematics but instead influenced by his father he followed his family’s wishes and began his career in the study...

...Chemistry and Society (Name) CHM/110 Due Date Instructor Chemistry and Society Chemistry is an important part of our society. It is used for manufacturing the products we use, medicine, and just about every other aspect of our lives. This document will discuss how society depends on the accuracy and precision of measurements, the difference between accuracy and precision, and compare and contrast accuracy and precision of different types of measurements used in our daily lives. Accuracy and Precision Since the bulk of this discussion is about measurements, we will start off by discussing the difference between accuracy and precision in that context. When making any kind of a measurement, we need to be able to get as close as we can to any certain number. The question often asked is, how close to the actual number can we get? If we can get close that number that would be considered accuracy. When we think about precision, it is a different concept. Once we have been as accurate as we can be with our measurement, precision would be how many times we can achieve that measurement. Can it be duplicated? Society Dependence on Accuracy and Precision When we think about all of products available in the open market, we, as consumers, expect consistency in the products we buy on a regular basis. For example, Diet Coke is product a lot of us love to consume on a regular basis. We expect that soft drink to have a certain taste and not be flat. If we were to buy it...

I decided only to keep one job because it was too hectic. My title for the job I kept is Student Success Leader, which is similar to a peer-counselor. With the other brief job, I was a tour guide for the CUNY-wide College Explorers program, which gives tours to middle school students, with the intent of having them go to college. I volunteer for South Bronx United, where I serve as a youth tutor to high school students. I was also offered an opportunity to work as a tutor for the math department at BCC, seeing how well I did on the placement exam and both my Calculus courses, I declined the offer because of all the tasks I was doing. Lastly, I was offered an opportunity by general chemistry II professor to do research with him. The research is on “the Determination of chemical composition in rainwater and snow in different locations at Bronx Community College of City University of New York (BCC).” In the end, I decided not to do the research as I was trying to make going to classes, working and volunteering along studying and doing homework...

...Chemistry and Society CHM/110 Chemistry Is Everywhere Humans are surrounded by chemistry. Every product one uses on a daily basis is linked in some way shape or form to chemistry. Food, clothes, electronics, vehicles and medicines are all made up of molecules of elements. Through chemistry these elements were combined to form alloys, plastics, fabrics, liquids and gases that make up these products. Chemistry, like other sciences, relies on accuracy and precision in order to remain a reliable source of knowledge and a means for advancement of various aspects of human life. This paper will discuss the importance of accuracy, precision and the scientific method in chemistry and how these affect the lives of the average humans. Accuracy and Precision Accuracy and precision are paramount in the realm of chemistry but it is important to note that even though these two things are related they are different. According to Merriam-Webster (2012), accuracy is the degree of conformity of measure to a standard or true value. For example, if one is taking a drive that is known to be 5 miles and their GPS reflects a distance 4.9 miles travel the GPS is accurate to within one tenth of a mile. While accuracy and precision reflect how close a measurement is to a standard or true value, precision differs in that it is a reflection on how reproducible these measurements are. For example, if the same GPS from above measures 4.9 miles each time for 5 separate time then it is a reflection...

However, while there is growing investment in the research and development required to bring CDU to the market, to date there has been very little systematic research into public perceptions of the technology. The current research reports upon the findings of a series of six qualitative focus groups (and an associated questionnaire) held with members of the UK public in order to discuss the perceived benefits and risks of CDU technology. The findings reveal that public awareness of CDU is currently very low and that there is a desire to learn more about the technology. While our participants did, on average, appear to develop an overall positive attitude towards CDU, this attitude was tentative and was associated with a number of caveats. The implications for the findings in terms ...

...Deciphering Leadership Styles Based on Gender Jean Peterson Kirtland Community College PSY 260 Deciphering Leadership Styles Based on Gender Whether we choose to believe it or not, the gender roles that are placed on us by society affect our leadership styles and how we view the leaders in our lives. How many times have you stereotyped a person as a natural leader, or decided a certain individual didn’t know anything about leadership? Most of us do this naturally, without even considering the reasons behind it. The focus of this paper is to explain how gender affects our leadership styles and the variety of pieces that make this topic a complicated puzzle. It is obvious that in our society men are viewed as more equipped and capable leaders. This is mostly because men are perceived as the dominant sex in America. Male leaders are expected to be autocratic. Many people view this as a baseline when considering leadership styles. After all, who wants a leader who can’t make decisions? Male leaders are often defined as strong, arrogant, intelligent, ego-driven, bravado, powerful, dominant, assertive, focused, competitive, stubborn, physical, self-righteous, and direct (Cummings, 2005). Because of these adjectives that are stereotypically placed on male leaders, many tend to veer toward men when choosing an appropriate leader. Men have been viewed in the same manner for centuries, and the societal norms tend to be much less judgmental on male leaders. Even though...

...Chemistry and Society Paper Chemistry is all around from the air we breathe to the water we drink, most people are not thinking of chemicals, but natural substances. Chemistry explains how the properties and behavior of chemicals are composed of atoms and molecules. The agricultural industry uses this knowledge to determine weaknesses and strengths in the crops they grow to determine yields. For instance a farmer may be having a problem growing a certain crop due to a deficiency of a needed element. I work for a company that provides needed elements for this industry. Verdesian Life Sciences provides nutrient based products for farmers. Accuracy and precision are concepts of great value to be successful. The products we provide must be accurate and precise to our claims regarding the guarantee analysis. Accuracy is the degree of closeness to true value based on a single factor or measurement. Precision is the degree to which an instrument or process will repeat the same value based on multiple measurements. Example will be the guaranteed analysis of a product that provides nitrogen, phosphate and potassium. When you test the product you are testing for the accuracy of the claim, however the precision is the result of using the product multiple times. Scientific method is a series of steps to prove a theory based on analysis from an actual experiment. We start with a question and based on our knowledge we form a hypothesis for the best answer. To prove or disapprove the hypothesis...

...The Relation between Forensic Science and Chemistry Isabelle Génier London Central Secondary School There is a great number of careers that involve chemistry; being a forensic scientist is one of them. What is a forensic scientist you ask? That is a very difficult question to answer. Generally they provide evidence in court to support the prosecution or defence in criminal and civil investigations. The evidence can be provided in the form of a written paper or the scientist might be called to testify during trials or hearings as an expert witness on evidence or laboratory techniques. There are different areas of forensic science such as chemistry (which involves crimes against property), biology (which involves crimes against people), and toxicology (which majorly involves drugs). Being a forensic scientist involves many tasks, they go to crime scenes to investigate and then plan what evidence they need to collect. Afterwards they return to compile, catalogue, and preserve evidence to help solve the case. They then do a sketch of the scene so that they can later reconstruct the crime scene to re-examine, test, and analyze the evidence. Now that the evidence has been assessed, it can be discussed between specialists and a report can be written based on their conclusions. The report is used during trials or hearings; however, the forensic scientist can also be called upon to personally testify as an expert witness. This career, which used to be an unknown field has now...
