Philadelphia - Essay Example During the Gettysburg Campaign of 1863, numerous other battles were fought in Pennsylvania. A cavalry raid 1864 ended with the flattening of Chambersburg. The Confederate States Army occupied the city of York, which was the largest city in the North they had occupied. Pennsylvania also contributed quite a number of generals and politicians during the war; some of them include George G. Meade who was the victor of Gettysburg, Winfield S. Hancock, Simon Cameron John F. Reynolds and Thaddeus Stevens who among the Radical Republicans was prominent and outspoken(Wikipedia, n.d., para. 4). Ways in which the commemoration of the civil war can be carried out would be at the Gettysburg National Military Park. Here there can be rangers to stage a living history camp with demonstrations and programs for adults and children. There can be battalions of both Union and Confederate forces complete with artillery. Re-enactors can gather so as to reflect the actual history with all the features such as battle re-enactments, demonstrations and encampments, civilian interpreters and horses and cannons. one event that could be a highlight of the event would be a ceremony to commemorate the †Gettysburg Address† by Abraham Lincolnat the Soldier’s National Cemetery. There can be events at Harrisburg which is just a short stretch from Gettysburg where we have The State Museum of Pennsylvania. This contains collections which before had been displayed at the Civil War Road-show that has now been retired. Also contained in the museum is the infamous epic painting by Peter Frederick Rothermel â€Å"Battle of Gettysburg: Picket’s Charge†. It also contains a collection of swords used during the Civil War acquired recently which are objects linked with The United States Colored Troops (Klein, 1980). The National Civil War Museum, also located in Philadelphia, contains rare artefacts and archived pieces from the South and North with recent sesquicentennial

Ruler Dropping Test to Measure Reaction Time

Ruler Dropping Test to Measure Reaction Time Problem statement It takes every person a little time to react to any event. For example, there is a small delay before you try to catch a ball moving towards you or trying to catch a falling glass from a certain height. This time is called your reaction time. There are many ways that you can measure your response time. Some of the methods are very easy (without calculation). One of the simplest and common methods of calculating response time is the ruler drop test. Most of the athletes use this methods to calculate their response time. In our engineering physics class we were asked to use this method to calculate our reaction time. For this assignment we were to be in small groups and measure everyones reaction time by getting 10 measurements from each student and determine who has the fastest reaction time. After taking the initial measurements we were also tasked to calculate the errors of those measurements. Coming up with a plan to asses this we encountered some major problems such as, How fast is our reaction time? With each measurement does our reaction time increase? Why we tend to catch the ruler in the middle rather than the beginning? How to improve our reaction time? After we have done this assignment we plan to solve each one of those questions while providing the answers to our assignment. What is reaction time? In this method one of the students drops the ruler, the student see it starts to move and nerve signal travels from his eye to his brain. The brain simulates the signal and sends it to his finger muscles which move to catch the ruler. The whole process takes between 150 and 220 milliseconds. The process of catching the dropped ruler begins with the eye watching the ruler expecting of it falling. After the ruler is dropped, the eye sends a message to the visual cortex (which simulates what we see), which perceives that the ruler has dropped and its falling. Then the visual cortex sends a message to the motor cortex (nerve stimulation) to start the process of catching the ruler. The motor cortex sends a message to the spinal cord, which sends a message to the muscle in the hand/fingers. The final process is the process that makes a muscle to become tighter of the muscles as the hand grasps the ruler. All of these processes involve individual neurons that transmit electrochemical messages to other neurons. How to proceed the test. What do we need? An accurate ruler. Two people(one to release the ruler and one to catch it) How to proceed. When we do this test one person has to hold the ruler and release that ruler at an unpredictable time. When the ruler start to fall (the test) the other person (test subject) has to pinch his fingers together catching it. This is his reaction to the falling ruler. The distance that we take (to measure) is the distance between the bottom of the ruler and the top of the thumb where the ruler has been caught. It is very unlikely that a student can stop the ruler at the same distance twice in a row. That means that we can get a more accurate measure of that students reaction time. We are conducting this experiment several times and take an average of our results. For this assignment we take 10 measurements from each student. How to calculate. To calculate ones reaction time we use the 3rd kinematic equation, 1 s= displacement. u= initial velocity. t=time taken. a=average acceleration. Proving, To prove the 1st equation, 2 We know that the first kinematic equation is, Applying this to the 2nd equation, How to use this to calculate reaction time Because the ruler is dropped down, Calculation To calculate the reaction time for each person we took 10 measurements from each person to get an accurate value. To get the most accurate value we calculated the mean of each person. Down below are the measurements we got. Every value is on cm scale. As proven above we are going to use two equations to calculate each ones reaction time and determine who has the fastest reaction time. 1 2 Looking at the results we found, we can see there are four people with a reaction time of 0.165s. This brings the idea of errors in this calculation and method.   What can be the errors in this measuring method? Thought processing speed is different in each individual. As I explained above when I was describing reaction time to catch the ruler the test subjects muscle has to work. Depending on the thought processing speed it varies. Because we are taking average metes of each person you can see all the averages are on the same range. That means even if one person went too far with the meters he can catch up with others with fast reaction time. Other thing is because the measuring system is analogue, people can make mistakes such as the person who is dropping the ruler is not consistent with his work (dropping the ruler). That can lead to errors. Conclusion Ruler dropping test can be the easiest way of measuring reaction time but it has its own pros and cons. This method requires very minimal amount of items to conduct the test. This method also not require a specialized pace to conduct the test and can be easily set up for the test. However there are few disadvantages as well such as this requires at least one assistant to support the test subject. Also because its simple it can be incorrect when it comes to the calculations as we can see above. In our given assignment we were to find a way to measure the reaction time using the ruler drop test. This leaves us with only one question, is it reliable to measure our reaction time with this method? REFERENCES [1]B. Mackenzie, Ruler Drop Test, Brianmac.co.uk, 2017. [Online].

An Orange Juice Label as a Microcosm of Society Essay -- Exploratory

An Orange Juice Label as a Microcosm of Society One facet of Herbert von Hundstein's theory of universality is that all components of culture, from obvious propaganda campaigns to written notes exchanged on refrigerator doors, are meaningful and representative of society as a whole. Von Hundstein writes in Kultur ist Alle; Alle ist Kultur, The most mundane may also be the most significant, for is our culture any less forgotten in the private conversations of two lovers? Culture does not exist in a vacuum: it permeates all like oxygen, and for that reason anything in existence is a product of its culture. (34) Therefore, a parking ticket, office memo, and orange juice packaging are all representations of culture. It is the orange juice label that concerns us here, and its promotion of ambiguity, assumptions of the audience's supineness, and reliance on other texts. The word "minute" has multiple meanings, as does "maid," and thus "minute maid" is infinitely problematic. Are we to assume that the "maid," an unmarried girl or woman, is only a maid for a minute? After those sixty seconds, is her virginity gone? If this is the intended reading, being the primary denotations for both words, then should this company really be selling orange juice and not sex toys? Examining the phrase "minute maid" from a grammatical viewpoint, we could easily extrapolate that "minute" here serves as an adjective, modifying "maid," and thus means "a very small" maid. Perhaps virgin dwarfs create orange juice. The company presumes to convey a quickness created through the additional services of an assistant, a maid making a laborious process go by in a minute; however, that reading is only one of many possible. During the 2000 preside... ... cause orange juice labels to be less ambiguous, assumptive, and intertextual in the future. Let us not oversimplify and assume that one orange juice label does not matter, that the simple commands "shake well before enjoying" simply fall on blind ears and deaf ears. As von Hundstein states, this orange juice label contains a microcosm of society: within its directives lie the problems and successes of society. The orange juice label thus serves as a litmus test of American culture in general, and we can determine that American culture requires a fairly informed populace used to interpreting assumptions and intertextuality to avoid problematic ambiguity.

Lennie is mourning the death of his puppy Essay

At the beginning of the extract, Lennie is mourning the death of his puppy – by his own hand – when Curley’s wife enters the barn and attempts to comfort him and she allows Lennie to stroke her hair. When ‘Lennie’s big fingers fell to stroking her hair’ we see that something is going to happen as the mood changes and the tension is heightened. We have an inclination to what is about to happen as we have seen the inevitability of the scenario with Lennie’s strength and Curley’s wife’s desire for affection and attention. When Curley’s wife tells Lennie not to ‘muss it up’, Lennie strokes ‘harder’, as he is overcome with the pleasure of the experience, this shows that Lennie doesn’t listen to anyone except from George, thus reinforcing what we already know. Curley’s wife says ‘ you stop it now’ and ‘jerks her head sideways’ and Lennie then panics and automatically his ‘fingers close on her hair and hung on’, this is because it is the only thing he can think to do, this emphasises his child-like mentality as his reaction is physical as opposed to psychological. ‘Lennie was in a panic’ and ‘his face was contorted’, these two short simple sentences portray the innocence and naivety of Lennie’s actions as well as reflecting the way Lennie’s mind works, short and simple. He ‘begs’ Curley’s wife to stop screaming because ‘George’ll be mad’ and ‘ain’t gonna let him tend no rabbits’ showing that he has a one-track mind, much like a child. Lennie then gets angry and tells Curley’s wife ‘I don’t want you to yell’, this again shows his child-like mindset and his anger leads him to shake her. So he’s shaking her, not in an aggressive manner, but to protect his part in the dream, ‘her body flopped like a fish’ and ‘she was still, for Lennie had broken her neck’. At this point we see Lennie, not just kill Curley’s wife, but kill the dream too. Lennie does not realise he has killed her as he continues to speak to her, he ‘lifts her arm and lets it drop’ and is, for a moment, ‘bewildered’. His mind can’t capacitate why she is not responding, all he thinks he did was shake her, showing just how unaware he is of his own strength. Animal imagery is used to describe how Lennie ‘pawed up the hay until it party covered her’, this connotes Lennie’s clumsiness and density. In the concluding paragraph of the extract we see Lennie become ‘conscious of the outside’ ‘for the first time’, he recalls what George told him to do if he gets into trouble and goes to ‘hide in the brush’, taking the dead puppy with him to ‘throw it away’ because ‘it’s bad enough like it is’. Here we see Lennie make a decision himself, be it the right one or not, he seems to have matured slightly because of the situation at hand and this event could be something that changes Lennie’s childish behaviour. Throughout the death of Curley’s wife, we still feel more sympathy for Lennie, because he is so unaware of the danger his actions can cause and he is still a naive and innocent character, despite the unintentional harm he has brought to many things.

Learning Team A Reflection Essay

Throughout this course, we established a foundation in understanding Business Information Systems. This week’s objectives were to describe how wireless technologies are used in the workplace and how to use spreadsheets in business situations. While some members of Team A were well versed in Microsoft tools, others had their first lesson on Microsoft’s Excel and Access fundamentals. Team A’s members range from a project manager who attained their Associate Degree in Computer Programming, a logistics specialists for Amazon.com, a employee in the Hilton Hotel industry, and a wine educator working in hospitality—all very different fields with varying levels of information systems background. While for some it was a review, Team A can all agree that each and every one of us gained a better understanding on how and why information systems accomplish business objectives. Cheryl knew the degree in which wireless technologies kept users plugged into the World Wide Web. She was aware that smartphones and their many accessories allowed users to access their emails, schedules, mobile banking and participate in e-commerce as well as make online payments—she learned that M-commerce another growing trend. Due to telemedicine, modern technology has allowed the medical world to provide assistance via videoconferencing. In addition, she learned that setting up and using access points to create meshed networks called a Wide Area Network (WAN) (Rainer & Cegielski, 2011). Xavier learned the relevance of wireless technology in everyday life. More specifically, he learned of the different functions of varying satellite types to communicate information. Kelly learned about the two basic operations of data mining. According to Rainer and Cegielski (2011), data mining functions in  Ã¢â‚¬Å"predicting trends and behaviors and identifying previously unknown patterns† (chap. 11). Angeliza discovered that Wi-Fi was abbreviated for Wireless Fidelity as well as the synchronization of using Microsoft Excel with Access. With the objectives of Week 3 in mind, Team A members have found varying ways in which we can apply what we have learned in the classroom into our professional or personal lives. As a project manager, Cheryl can utilize Excel to track cost of goods (COGS) inventory. As a logistic specialist, Xavier can use spreadsheets in generating employee lists and creating reports to reflect the volume of freight used on a daily basis. As a team member in hospitality, Kelly can use data mining to track hotel guests’ sign up and preferences. In customer service, Angeliza can use the point of sale system to analyze the day’s sales and returns (Rainer & Cegielski, 2011). The learning activities and readings have left each member of Team A with a little more knowledge than we had previously. Cheryl knows that Microsoft Excel and Access are a perfect duo: Excel creates the tables that can be exported to Access where the data is analyzed. Xavier learned how to more effectively incorporate spreadsheet into his daily work routine. Kelly understands the role of wireless information systems in the creation of invoices for clients and making it easier to calculate daily cash sales. Angeliza learned that she doesn’t need to be an IT specialist to analyze data from Excel with Access. Despite our different backgrounds, Team A members can agree that we all gained a better understanding on how Information Systems plays into effectively and more efficiently completely business goals. Week 3’s lesson on spreadsheets and wireless technologies makes us more proficient in the language of information systems in the workplace and in our daily lives. Reference Rainer, R.

Ten top writing tips for scientists - Emphasis

Ten top writing tips for scientists Ten top writing tips for scientists Ask most scientists, engineers and technologists why they got into the profession and theyre unlikely to say it was because they love writing. But love it or hate it, writing is an essential part of a scientific career. Report writing skills are crucial to communicating your research, ideas and recommendations. Losing the gems of months of research in confusing, convoluted prose helps neither you nor your readers. The way you write can be more important than what you write. An instantly readable report will usually have more impact than one that is difficult to decipher. Science doesnt exist in a vacuum. So if you cannot communicate effectively to colleagues and the general public, your work is likely to be perceived as less important. In fact, if you cant communicate what you do, you could argue that you might as well not do it in the first place. Here are some top tips and techniques that can transform your written work: 1. Ask the right questions Powerful writing starts from an ordered, clear structure. Begin ordering your ideas by asking yourself the questions: what? where? when? how? why? and who? When you know what you want to communicate, and why, you can then lay out your core idea first, and expand on it in the rest of the document. Always make sure you ask yourself the exact purpose of what you are writing. When you have a clear intent, you have a much better chance of crafting an effective document. 2. Use jargon with care Abbreviations are a great shortcut when you and your reader speak a common language. But dont forget that there may be acronyms and abbreviations that people outside your organisation or area of expertise just wouldnt know. This doesnt mean that you have to avoid jargon at all costs. Just be aware of your readers knowledge and choose the words and phrases that you are certain they will understand. Most people overestimate how much their readers know and bombard them with too many technical words and phrases. 3. Focus on your reader Do your readers really know everything about thermodynamics or mass transfer? Or are they more concerned with how the science affects their environment, a product or the companys bottom line? Ask yourself the following questions so that you can tailor your information to your reader. Who will read the document? How much experience do they have of the subject? How much do they know about it? What is their likely attitude towards it? How involved in the subject are they? How interested are they in the subject? 4. Dont show off In academia, the more knowledge, information and argument you display, the higher the marks. In the outside world, only the most significant information is necessary. Summarising a wealth of related issues may at first appear to cement your expert status, but it doesnt help your reader. Managers often have several reports to read each day, so focus on becoming a solution provider. 5. Create a compelling opening paragraph Research has shown that when it comes to focus, people remember the beginning and end of something, plus a high point in the middle. This is as true for reports as it is for holidays or feature films. So make sure that your conclusions and recommendations are in the summary. If you bury your recommendations in the middle, theres no guarantee that your readers will get that far. 6. Be confident Say what you really mean and your readers will thank you for it. It can be a little disconcerting to write clearly and in plain English, especially if you come from an organisation that doesnt encourage having a definitive viewpoint. But it will help you to become recognised as a thought leader and means that your work reaches a much wider audience. 7. Learn how to KISS Keep it short and simple. Avoid long, flowery phrases and make sure your sentences contain a maximum of 15 to 20 words. Presenting information in short, manageable chunks also helps you to keep the reader with you, so stick to the principle of one idea per sentence. To paraphrase Einstein: make things as simple as they are but no simpler. 8. Get active Where possible, use the active voice rather than the passive one. Instead of writing, the reactions of various metals were tested, write we tested the reactions of various metals. Adding in the word we makes the document more personal. Dont be afraid to use the word you when writing reports for non-scientists. The idea is to engage the reader and active, personal language does just that. 9. Check for errors Always proofread carefully by printing out your document and combing through it word for word. You cannot rely on your spellchecker to know the difference between palate and pallet, especially if you have it on the automated setting. Print it out first. And if possible, put your work aside for a day and come back to it with fresh eyes. Its likely that any errors will jump out at you more easily. Also check for punctuation and make sure that your structure is as effective as it can be. 10. Use a style guide Grab a free copy of our new The Write Stuff (third edition) to help you with the writing process. This 60-page style guide contains the very essence of good writing. Request a copy here. How Emphasis helped scientists to write more clearly One of Europes leading pharmaceutical companies asked Emphasis to improve its scientists report writing skills. The problem? Many of their written reports were failing to communicate the results of their research and development work in a clear and concise way. The training programme changed how the scientists approach, plan and structure their reports. Before the training programme, most people saw writing as an irritating distraction from their research and their reports had to be heavily edited. Now, there are fewer amendments, the medical director explains. This has reinforced the lessons learned during the training, creating a positive cycle that has, in turn, promoted better writing throughout the company.
