Benjamin Franklin Physics free essay sample

However, he is probably best known for his work in science, especially in electricity and the physics of electricity. For the areas of science In which he worked, he Is known for his studies In the theory of electricity and his useful inventions. These include the Franklin stove, bifocal eyeglasses, the lightning rod, and daylight savings time. One of Franklins greatest claims to fame was his work in electricity. He carried out experiments with the Elided jar, sent a current through water to ignite alcohol, made the first battery, ignited gunpowder, ND much, much more (Bells).He even charged wine glasses so the drinkers would receive shocks! More importantly though, he began to develop the theory of the relationship between lightning and electricity; he brought up the idea of protecting buildings by using Iron rods. In the summer of 1752, he performed the famous kite experiment, where he drew down electricity from the sky by charging a Elided Jar from the key at the end of the string. We will write a custom essay sample on Benjamin Franklin Physics or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Franklin stated that electricity is a single electrical fluid' (electrons) that may be transferred between bodies.He said the total quantity of the fluid is always conserved. This is a concept known today as one of the fundamental natural ?the conservation of electrical charge (Timeline 1750-1774). Inspired by Fay (Charles-Franà §ois De Fan best known for the discovery of positive and negative electricity, Franklin found out the amount of fluid (today known as electrons), was responsible for the repelling and attracting of different objects In different situations (Karma 340). Ben]amen Franklin used terminology still used today.An excess of electrical fluid was considered positive while a deficiency of fluid was considered negative. Benjamin Franklin studied the relationship between magnetism and electricity and tried to magnetite an object by using electricity. Today, we know that electricity Is generated by either moving a wire in a magnetic field or moving a magnet in a coil of wire (Generating Electricity). Benjamin Franklin was also known for his many inventions and creations, which were involved in his experiments with electricity and magnetism (Inventions).What fascinated me about Bens inventions was that most of them were created because he had a problem and wanted to fix It. Franklins Inventions remind me of all the cool new technology we see every day on TV or Channel One News. It continues to amaze me how interesting Benjamin Franklin was by studying his inventions alone. Benjamin had weak vision and was always taking off/ putting on his glasses for reading so he created bifocal glasses to be able to see near and fall Franklin suggested using Chinese ship models, where the ship would be divided into watertight compartments.This way, if the ship had a leak, it wouldnt sink the whole invented the Franklin stove so people could warm their homes safer and without using as much wood (Dray 31). Benjamin Franklin may in fact be one of the most well- known Americans of the . He was surely my favorite! He had a major role in the founding of making the United States and independent country. In science, he is remembered for his many studies in the theory of electricity and his many useful inventions. He was a writer, scientist (many areas of science, especially physics), politician, and many more things.

Bob Dixon Essay Example

Bob Dixon Essay Bob Dixon owns a small Theatre in Woodford Green, it is called Woodford Green Theatre. His theatre is not the best in London but it is highly rated. He has 1 theatre and hosts 1 show every month. His theatre may be quite small but it is old and worth a lot of money, a lot of the theatre has been refurbished and made more modern, but the only thing still not up to date is his way of working.. Since he opened the theatre he has used a paper based system for everything. He has used it for financial records and writing out the tickets and everything in between. He needs a computer to, have an automated system of seating, and to keep record of booked tickets and seats. Problem Identified The problem with Bobs way of keeping record is that he uses a paper based system and he has to file this all the time, if he loses one piece of paper he can be really be in trouble. On a paper based system he has to calculate on his own, if he changes a number he will have to re-do the whole sheet again. And if he loses something he will not be able to get an accurate result in any area and this could mean that he thinks he has a profit when he actually has a loss. If he keeps his paper based system he will have a lot of trouble in the future and will find it hard to show his records.

This would mean he has to spend more than necessary. I think this could become a bigger problem as time goes on. Bob has heard of mail merge, mail merge has many advantages so I can see why he would want it, it means he does not need to write all of the letters on his own like he does now, he an use mail merge to automatically send the same message to many people quickly. Bob would also like to use it to send vital information to customers who wish to see it, critics and news papers who wish to write about him and his theatre. Another problem that Bob has found is that, the member of staff who is in charge of the ticket booking has walked along and a booking for 4 or 5 tickets has fallen out of the folder and she did not realise and none has told her, so she looked back and she has 4 or 5 tickets missing from the order and she re-sells the tickets to other people and then she then has 2 sets of people arriving for the same tickets and then has to refund the money and the theatre will then get bad publicity. Bob uses a filing cabinet system to store his paperwork. This is not good, they can collapse and they have a limited amount of space in them. This means he will have to either get rid of all his older paperwork, which is never clever, or spend even more money on more and more filing cabinets this is just a waste of money he could use on more important things and trying to get the theatre looking its best and costume and makeup for shows. When in the long run a computer based system will be cheaper. Bob uses paper to file everything including his stock levels, this could be bad, he could lose track or miss calculate how much in coming in and going out this could end up with Bob not knowing if he has profit or loss. He writes every address out by hand which takes up a lot of unnecessary time. He works everything out in his head or on the calculator which is also time consuming, and can lead to incorrect results. In conclusion he needs to upgrade or he will never be able to have a 100% accurate reading of any data and he uses up all his time which he needs, in order to make sure the theatre is running correctly. Bob is going to upgrade and use a computer based system and then finally have time to spend on his running of the theatre. Problem Solutions Advantages and disadvantages of each of the software Microsoft Word Microsoft word offers my user share trading activities: 1. It can record information like names in a table that is clearly set out. This is an advantage to Bob because he can see all the customers and their details easily and quick, this is good for finding out any information they need in a quick and stressful situation. 2. Can receive guidance when writing a business letter to the tax office (or mail merge in some tasks) this is an advantage because he can now have more time to do more important tasks and leave the letters to the computer. 3. Can create promotional posters with graphics. This is help bring in business for Bob. Microsoft word lacks: 1. Bob can not count the number of banking shares that he holds. 2. Bob can not calculate how many days that the he has held a particular share. 3. Bob can not put all shares into ranking to compare their performances. 4. Bob can not hold formulas at any point that are able to work. Microsoft Access Microsoft access offers my user: 1. Mail merge, Microsoft access allows Bob to save the addresses and have them automatically send to that address. 2. Access contains Wizards that walk Bob through each step of the way. Bob does not need to have database experience in order to use it. 3. Bob may build as many unrelated databases as hed like. Microsoft access cannot offer my user: 1. Microsoft Access is not meant to have multiple users at any given time. While it can support them, problems with functionality can pop up. 2. All the information from Bobs database is saved into one file this can limit what you can do with it and slow down reports, queries, and forms. 3. Access is a simple database, not a full-fledged database management system. 4. Each database can store no more than 2 GB of data. 5. Since Microsoft Access cannot handle large data requests, if you are using close to the maximum amount of data, it will run slowly Open Office Calc A comparison with Microsoft open office calc and Microsoft excel: 1. Open a previously created MS Excel spread sheet with Calc. I found absolutely no errors in opening the file. There were no special translation messages. The Excel spread sheet simply opened in an Open Office Calc window. All formulas and other formatting and features translated over fine as well. This will help Bob because they are easy to open making it efficient for Bob. 2. I have made extensive use of Excel formula capabilities, and found that pretty much anything I wanted to do, I could duplicate in Calc. This will be good for Bob to back up all his work. 3. The process of formatting cells was basically the same as in Excel. The menu options were substantially the same. I was able to define text cells, currency, and number of decimal places, Wrap Text and other functions with no problem. This is helpful for Bob because I can do all this for him before he gets the spreadsheet and he will not have to do it himself. 4. I use heavy and thin borders, and like to select my own colors for shading and backgrounds. Calc offers only one line thickness and one line color (Black). This means Bob can customise the mil merge designs easier. 5. Creating a Data Range proved fairly simple I did have a bit of trouble figuring out how to remove it and create the range I wanted. The disadvantages in my investigation between open office calc and excel: 1. I did discover that there were some slight differences in how formulas were structured. For example, in an Excel If statement the format is =if(A1=10,1,0) meaning if cell A1 equals 10 then put 1 in the target cell, otherwise put a zero in the target cell. In Calc the same formula is written =if(A1=10;1;0) 2. One thing I did find disconcerting was Calcs propensity zip across the spread sheet too quickly. It flew up, down, left or right, if I happened to need to extend the graph target to a point that was off the screen. Once it hits the edge of the visible cells, it takes off like a rocket. 3. In Excel, if you highlight a cell and hit the delete key, the data in the cell is deleted. In Calc, the same operation will generate a pop up menu that give you multiple options for deleting. I initially found this to be an irritant, though I can see that it could be handy. Excel uses different delete options to provide the same functionality. Microsoft Excel The advantages of Microsoft Excel: 1. Once you have entered the formula that is needed, you can keep changing the data and it will keep calculating for you without you having to do anything. 2. Bob can use functions for example, IF, Average, Min and Max. 3. He can use Mail merge, create graphs, use formatting, validations and Macros 4. Excel files can be password protected for extra security. A user can create a password through Visual Basic programming or directly within the Excel file. The disadvantages of Microsoft Excel: 1. Users must create subset directories for data management. Excel data can be lost when the application is broken down into many files. 2. Viruses can be attached to an Excel file through macros. Macros are mini programs that are written into an Excel spread sheet. Solution Description The solution to his problem is just simply Excel. Excel provides so many helpful ways of keeping your data safe, laid out clearly and hard to completely lose. This program is specialised in spreadsheets. This will help Bob make sure he has all his data clearly set out and Excel also provides him with being able to send any important information to his business partner Steven through mail merge (the mail merge tool in Microsoft word allows you to print a series of standard letters or documents with particular details(such as names and addresses) changed on each one. The details which are to be merged into each letter are typically read from an external file such as an Excel spreadsheet or an Access database). Mail merge is better than just typing addresses into the word document individually; it is better this way because it saves time and effort. At the moment he sends out over 100 people a month that would take ages to type out, it also reduces the mistakes possible to make. Bob wil l be able to access any data a lot quicker now than he could before there are many applications on Excel, like, the SUM button () for example, this button is an easier way to add, find the average, find the maximum and find the minimum of any data in the spreadsheet. Another good thing about Excel is that it will always be on your computer as long as it is running okay because you do not need the internet to access it. There is only one minor problem and that is that you have to pay to have Excel, either when you buy your computer and you ask for it, if you buy the excel package or if you pay for it on the internet. This is a program that is worth the money because once Bob has it he will not stop using it until he gives up his shop. This is the best possible solution for Bob at this stage and he will find himself in an easier placement when he has to show his fanatical history to anyone. Chosen Solution My chosen solution for this project is Microsoft Excel Compared to other possible solutions, what are its advantages? Unlike Open Office Calc, Bob Dixon can open, amend and save work without any problems in Excel on most computers. Access is helpful for Bob Dixon to store information about each share; however, Bob will not be able to find out the total profit/ loss he has made on his shares in Access. Microsoft Excel offers many features which Bob Dixon will find it very helpful. For example, all shares can be put into ranking according to their performances; functions such as average can be used to calculate the overall performance to the shares. Can be used to calculate the overall performance of the shares. I am planning to use graphs and charts to show data, conditional formatting and absolute cell reference. Quantitative Objectives Excel is a program that will help, it will be able to: à ¯Ã‚ ¿Ã‚ ½ It is easier to look at and understand (clearly set out) this is useful to Bob because it will make it is easier to navigate around the spreadsheet. à ¯Ã‚ ¿Ã‚ ½ If the show is making à ¯Ã‚ ¿Ã‚ ½10,000 a month the spreadsheet will say Rich!, it does this through IF statements, these will show the reader of the spread sheet in one word(by working it out) whether they are making a profit or a loss or even break even . This will help Bob because he will be able to quickly take a glance at the spreadsheet and know if he is going to have to make changes or not. Plus he can see what needs improvement. à ¯Ã‚ ¿Ã‚ ½ The spreadsheet can be colourful; it can use the colours of the organisation. This will help Bob because it will stand out and look professional. à ¯Ã‚ ¿Ã‚ ½ Mail merge is a good way to share any dates, prices or conformations to many people in one quick click. à ¯Ã‚ ¿Ã‚ ½ In the spreadsheet he can use goal seek, this will tell Bob how many tickets he will need to sell to make a certain amount of money, for example if the tickets cost à ¯Ã‚ ¿Ã‚ ½50 each, and he needs to make a minimum of à ¯Ã‚ ¿Ã‚ ½2000 the goal seek will tell him he needs to sell 400 tickets. This benefits Bob because he can see if he has any seats left to book. à ¯Ã‚ ¿Ã‚ ½ V lookup will do the same as an IF statement but it will provide him with as many statements as he needs where IF statements he can only have a maximum of three statements. This can mean they he could have more information shown in a smaller space. Performance indicators Excel is fit for purpose; it will fulfill the needs of the task. This software will be the easiest to use in this particular case because it meets the needs of the user. Bob will be able to easily work it using my user guide attached to this document. This software will also be set out in the easiest format for the company and making sure it fits the needs of the theatre. Excel will be able to do much more automatic functions than other software making it quicker and easier to use. Bob will not have to do much or spend a lot of time typing up data.

The sport industryal - Assignment Example The sports business means different things to different people , most importantly the athletes who require the use of the sporting goods to achieve fame and personal fulfillment, secondly the business people where in sports provides a continually growing market place worthy of investing, for the developers and the local government where in revenue is built from tourists and local fans. In the U.S, the ‘Big 4’ leagues bring in about $17 billion in annual revenue, the sporting good sales at retail stores roughly contribute about $ 41 billion yearly. On an annual basis around $400- $425 billion is contributed by the U.S sports market alone. The industry is so vast and complex that it makes it difficult to put an all encompassing figure to the yearly revenue. Many of the workforces in nations like U.S, Europe, Australia and Japan rely on the sports industry for their livelihoods, with figures increasing constantly for professional athletes, coaches, scouts, umpires, referees, and other officials etc. The global meltdown in 2008-09 had a big impact on the sports industry. Manufacture of sports equipment dropped, even the sale of tickets were difficult, since tickets for professional games were very expensive. Golf courses suffered revenue declines and some of them even closed. Most affected were the sale of high end sports and recreation items. The sports industry faced significant challenges in controlling expenses while pricing products and services such that they would still retain and attract new customers. (Introduction to Sports Industry, n.d) Like in any industry politics play a very important role, this comes into play when sports completions cross borders, for example in another country, city or even locally. In countries like China it is the national policy that drives decision making at higher levels. Following of national policies closely can help predict

Economic principles Essay Example | Topics and Well Written Essays - 250 words

Economic principles - Essay Example I find them much appealing to my values as compared to those that do not bear the incentive I desire. For instance, I am more than ready to study hard so that I can gain the incentive of one day becoming a successful economists. Another case is that I like helping others who are facing hardship because I believe they might be of use to my political agenda at one moment in time. In both of the above cases, there is always that incentive that motivates my present behavior. â€Å"Opportunity cost† is the other economic principle that often characterize my life. I desire so much yet I cannot get everything I want at the same time. For example, I like sleeping!!!! (But for the fear of being misquoted as lazy I accompany it with a disclaimer). On the other hand, I also want to attend classes so that I can gain the necessary knowledge in my major. Since I cannot sleep and attend classes at the same time, I am always forced to give up on sleep for the sake of attending classes. In this case, sleeping becomes my opportunity

Childrens Literature Essay Example for Free

Childrens Literature Essay It is hard to imagine a world without books for children. Ever since there were children, there has been childrens literature too. There have been childrens stories and folk-tales when man first learned to speak. Childrens books, however, are a late growth of literature. Miss Yonge says, Up to the Georgian era there were no books at all for children or the poor, excepting the class-books containing old ballads and short tales. We shall nevertheless see that there were English books for children long before this time. In western Europe, there was no separate category of books for children before the eighteenth century. The Bible, stories of saints and martyrs, and bestiaries or books about exotic animals, were probably the first printed books available to children. Childhood, as we think about it today, is a relatively new concept. Until the 17thcentury, children were thought of as small versions of adults and treated accordingly. In most societies, children were a source of labor. There were some books (mostly for the children of wealthy families) even before the invention of movable type by Gutenberg in 1455, but they were instructional in nature and were used to instill lessons of morality, manners, and religion.. With the rise of Puritanism in England early in the seventeenth century, literature for children became moralistic. Seeing children as amoral savages needing to be taught right, society used stories filled with death and damnation to frighten children into good behavior. Humor and imagination were banned. The Sunday School Movement of the late eighteenth and early nineteenth centuries, which aimed at bringing religion to the working class, continued the didactic tone in the thousands of cheap tracts of simple stories distributed throughout England and the United States. Over the next centuries, there was a gradual shift in attitude toward children which was reflected in the reading material produced for them. Hornbooks and chapbooks appeared, still designed to instruct, but some included woodcut illustrations in addition to ABCs and religious lessons. The most famous and prolific publisher for children of the 18th century was John Newbery. He published books which were immediately attractive to children: in a small format, with illustrations, and bound in brightly-coloured flowered paper. In the 18th and early 19th centuries, Robin Hood, Mother Goose tales, Robinson Crusoe, and Gullivers Travels were published and were the most attractive to the world of a childs imagination. A Visit from St. Nicholas by Clement C. Moore was published in 1823 and was one of the first works to introduce humor and laughter into the world of childrens literature. The Victorian era was a golden age for childrens books. Victorian family life is realistically depicted in Louisa May Alcotts Little Women (1868), whereas Mark Twains Adventures of Tom Sawyer (1876) and Robert Louis Stevensons Treasure Island (1880) emphasize adventure; all three books present fully developed characters. At the turn of the century several childrens magazines were being published, the most important being the St. Nicholas Magazine (1887–1943). It was also the time of classic books , such as Alice in Wonderland, and great illustrators Kate Greenaway, Edward Lear, and Howard Pyle to mention a few. In the middle of the 19th century, there were major changes in illustrations of books. Until then, wood engraving was the norm; with the development of chromolithography, which permitted printing in many colors, the world of book illustration changed dramatically. Great writers teamed with great illustrators to produce the books. The industrial revolution led to advances in printing which made books colorful, affordable, and plentiful. The growing middle class, with its increased interest in education, expanded the audience for childrens books. Walter Crane, whose work is highlighted in this exhibit, was a British artist and one of the first people to use the new printing techniques to bring color and design techniques into the world of childrens literature. The twentieth century continued a publishing industry for young people with adventure stories, series books like the Hardy Boys and Nancy Drew, science fiction and fantasy. During the 20th cent. in particular, new collections of tales that reach back to the oral roots of literature have come from Europe, Asia, Africa, and the Caribbean. International folktales have also received increasing attention. Among the many authors pursuing these themes, Verna Aardema compiles African folktales and Yoko Kawashima Watkins studies Asian oral traditions. During the 1980s and 90s in particular, multicultural concerns became an important aspect of the new realistic tradition in childrens literature. From the 1960s through the 90s socially relevant childrens books have appeared, treating subjects like death, drugs, sex, urban crisis, discrimination, the environment, and womens liberation. Recent years have brought books of children related to movies and commercial products from Disney to Star Wars as well as the psychologically-oriented young adult novel. The great scientific and societal changes of the early twentieth century had a great influence on the adventure story. The exploits of the World War I fliers replaced the cowboy and big game hunter in the dreams of young boys. Many of these adventure stories were published in long series, written by different writers all using the same name. The best known was the Stratemeyer Literary Syndicate which produced such series as the Rover Boys, the Hardy Boys, Tom Swift, the Bobbsey Twins, and Nancy Drew between 1906 and 1984. Maurice Sendak and Chris Van Allsburg are two important and contemporary childrens book author who publish their stories todays.

Review of an Ecological Science Research Article from a Primary Scientific Source :: essays research papers

Powell, K., 2005. Fish farming, Eat your Veg, Nature, 426, 378-379.   Ã‚  Ã‚  Ã‚  Ã‚  The article that I chose to review discussed the possibility of maintaining and sustaining aquaculture by changing the diets of the farmed fish. The idea of carnivorous fish turning into vegetarians would help for future sustentation of aquaculture. There were pros and cons to either side of vegetarianism and the maintaining of carnivores. There are issues that would require research and analysis to which the author points out to the reader.   Ã‚  Ã‚  Ã‚  Ã‚  Aquaculture has increased by 5% over the past 10 years. The wild stock of fish that is caught to feed the fish farms has numbered 11 million tons, which is 12 % of the total fish hauled from the sea each year. Carp and tilapia are the most farmed fish in the industry that already are consisting of a vegetarian type diet. Salmon and trout are the next largest farmed fish. The difference is that the salmon and trout are carnivores. The author reports that the carnivorous fish are more expensive to cultivate and more resources are needed to maintain these types of farmed fish.   Ã‚  Ã‚  Ã‚  Ã‚  Most farmed fish are fed on a diet that consists greatly of fish oil and fishmeal. Fishmeal is made from a protein rich powder of ground up cheap fish as a source of nutrients and proteins. The problem with using these within the farm diet is that the demand for the fish oil will overpower the supply as aquaculture expands and booms. The author states that the â€Å"demand will outstrip supply of oil by 2010.† (Powell).   Ã‚  Ã‚  Ã‚  Ã‚  Feed companies which supply the fish farms with fishmeal and fish oil as a staple to the diet of the carnivorous fish will seek different sources of protein. This protein could possibly come from larger fish such as mackerel, herring, and blue whiting. If this happens it would put more pressure on the natural stock already being harvested for other purposes. Some companies are traveling to the Antarctic to collect krill, which has repercussions for the bottom of the food chain in that the ocean itself is a primordial web of life.   Ã‚  Ã‚  Ã‚  Ã‚  The author boosts that the fish will be able to eat Soya beans, corn, rapeseed, sunflower seeds, flaxseeds, and wheat gluten if converted to a vegetarian diet. The author also reports that some salmon farms already use these foods as staples in their fish farm diets.
