Monet Vs. Van Gough Essay Example

Monet Vs. Van Gough Essay Between 1858 and 1882 Monet painted 49 still lifes, and 21of them were of flowers. In his Chrysanthemums, the subject combined his interest in gardening and painting.A relation that was displayed even more after he moved to Giverny in 1883. Like his Bouquet of Sunflowers of 1881, this still life was probably painted when bad weather had driven the artist indoors. This still life display colors, rhythm, surface and touch to the fullest extent. In Van Goughs Oleanders, he believed that these flowers were joyous, and that they bloomed riotously were continually renewing themselves. In the painting the flowers are placed in a jug, which is symbolically adjacent to a book titled, La Joie de Vivre by Emile Zols. The flowers seem to be leaning towards the book, like how they would lean towards sunlight. Although they are opposites being Monet more classic and Van Gough, I like to call him, stylish, they both did their painting beautifully, the way the subject is brought to life with color . But what I truly loved was their totally different style and painting techniques. Monets style of painting where the subject appears to be blurry and being able to notice his delicate brush strokes in the petals of the flowers, along with his choice of colors give the painting a classic feel to it.You can see somewhat of a reflection of the vase and flowers on the table; again Monet uses his blurry technique. The light blue background gives it a calming, peaceful effect.

Experiment in Artificial Selection essays

Experiment in Artificial Selection essays In my study, I wanted to see if I could breed a trait (Longer petial stem length) in Brassaca rapa by following an artificial selection design. The study was also used in order to monitor the mechanisms of evolution. To do this, I wanted to see if cross pollinating plants with the trait I was looking for would show the selected trait I was looking for in the offspring. My experimental design was to record the data for the parent generation and then to cross-pollinate the ten plants with the longest petial stem length. Once the seeds were ripe, I planted on hundred seeds, even though many more were produced by the plants. After recording the data for the F1 generation (Selected Offspring) I compared the data with that of the parent generation (The first plants). The results were quite amazing. The data concluded that the F1 generation did in fact have longer petial stems compared to the parent generation. The experiment was a success. Before even beginning the experiment I knew very little if nothing at all about Brassica rapa, let alone that it even existed. I had, at the recommendation of the Teachers Assistant (Kelly Garron), done a little research on the Wisconsin Fast Plant by doing a short internet search which revealed some information. After learning a little background information on my test subject, I proceeded with the Experiment Brassaca rapa, other wise known as Wisconsin Fast Plants, has green foliage with the upper leaves partially clasping the stem. The stems are well branched, although the degree of branching depends on environmental conditions. The flowers are pale yellow, densely clustered at the top with open flowers at or above the level of terminal buds, and open upwards. B. rapa ¡Ã‚ ¯s pollination mechanics allow for self pollination (Asexual reproduction) as well as pollination from other B.rapa ¡Ã‚ ¯s. In the case of outside pollination, pollinating insects, in particular honey bees and bumble bees, are belie...

A Guide to Hyphens and Dashes

A Guide to Hyphens and Dashes A Guide to Hyphens and Dashes A Guide to Hyphens and Dashes By Mark Nichol This post details the purposes of various horizontally aligned typographical symbols. Hyphen Hyphens perform various functions, including the following: They link standing compound words (mind-set, self-respect). They are used with some prefixes (anti-inflammatory). They represent expression in isolation of a prefix or a word element (pre-, -er). They link spelled out numerical terms representing different place values (twenty-four). They link words in phrasal adjectives preceding but not following a noun (â€Å"short-term investment,† â€Å"off-the-cuff remark†) and when combining similar-looking constructions that begin with comparative adverbs such as better, much, and well (â€Å"best-kept secret†) Some style guides (but not this site) recommend that phrasal adjectives be hyphenated regardless of their position, and a few such expressions (such as far-reaching) are always hyphenated regardless of position or style authority. Also, a letter space should never intervene when a hyphen connects two words or numbers, except when suspending the first use of a word common to two or more phrasal adjectives (â€Å"fifteen- and thirty-day increments†). Hyphens are often introduced when new compounds are created, including in technological vocabulary, but such terms usually become closed compounds (though there are exceptions, such as mind-set, mentioned above, and light-year). Some terms that include letters linked to nouns retain hyphenation (A-list, T-bone, X-axis). Omission of a hyphen in email is trending, but similar terms such as e-commerce resist this evolution. Em Dash The dash, technically known as an em dash (to distinguish it from the en dash, described below), is used to indicate parenthesis when more emphasis is intended than indicated by a comma or a pair of parentheses. One dash is employed to when the wording expresses an attempt to get attention (â€Å"Look- a squirrel!†) or to indicate a sudden break in syntax and the parenthesis ends a sentence (â€Å"What I meant to say is- hey, are you paying attention?†) Similarly, it can replace a colon (â€Å"You have three options- fight, flight, or surrender†). Two dashes are employed when the parenthesis occurs mid-sentence (â€Å"The original version of the document- the one I hold here- is worded differently†). The dash is also employed to set off the identification of the source of an epigraph (â€Å"‘The only thing we have to fear is fear itself.’ - Franklin D. Roosevelt†). Also, one or more dashes may indicate redaction of all or part of a word or name in order to avoid identification or euphemize profanity (â€Å"The target was identified as - - - †; â€Å"Ms. A- - is not unacquainted with scandal†; â€Å"Well, I’ll be d- - ed!†). Dashes are usually closed- that is, they are set with no preceding or following letter spaces- but some publishers prefer to format them open. Some, too, out of ignorance or apathy or for the sake of simplicity (as in the case of some newspapers), use a single or double hyphen in place of an em dash- or, because they prefer its size, employ an en dash. (This is a valid design decision, but use of a single or double hyphen appears amateurish and should be avoided.) En Dash The en dash, always so called to distinguish it from the default em dash, which is often referred to simply as a dash, has two functions: representing a range of numbers or a time span (â€Å"Read pages 15–37†; â€Å"John Smith [1936–2012] is not listed†; â€Å"These figures represent revenues during the first quarter [January–March]†) as a substitute for through serving as a substitute for a hyphen in a compound term (â€Å"Pre–Civil War conditions sometimes prevailed†; â€Å"The United States–Mexico border is nearly two thousand miles long.† (These distinctions are, again, sometimes ignored.) The en dash is employed for the latter use because â€Å"pre-Civil War conditions† implies â€Å"before the Civil† rather than â€Å"before the Civil War† and â€Å"the United States-Mexico border† appears to refer to a united border between States and Mexico rather than one between the United States and Mexico. Plus Sign A plus sign (+) is employed in mathematics and other disciplines to indicate addition or positive numbers, and in lay usage it may modify a letter grade or qualify a blood type. It is sometime used informally to indicate a value greater than the stated one, as in â€Å"I would say 50+ people attended.† (Formally, â€Å"I would say more than fifty people attended† is better, and a direct quote would be better represented as â€Å"I would say fifty-plus people attended.†) Minus Sign A minus sign (–) is a distinct symbol used in digital displays of mathematics and other disciplines to signal subtraction or negative numbers; like the plus sign, it may be used in designations of letter grades and blood types. However, a minus sign is often represented by a hyphen or an en dash in print or online. Multiplication Sign A multiplication sign (Ãâ€") is used almost exclusively in mathematics and in isolated functions in notations in biology and history. In lay usage, the letter x generally takes its place. Division Sign The division sign, officially called an obelus, was replaced by the dagger mark († ) as a reference sign and now pertains exclusively to division in mathematics. Equal Sign An equal sign (=) represents equivalence and is occasionally used in informal writing in place of equals. Tilde A tilde (~) usually functions to denote a variation in pronunciation of certain letters in various languages, but it also serves in informal writing to signal approximation, as in â€Å"We continued along for ~20 miles.† Underscore The underscore (_), employed on typewriters to create underlines, survives now mainly as a symbol in email addresses, URLs, and computer code.

What were the legal and ethical ramifications of the mid 1980's Research Paper

What were the legal and ethical ramifications of the mid 1980's insider trading scandal - Research Paper Example The stock trading of an organization as well as other securities, which include bonds or stock options, by people who have significant inside information about a company is called the insider trading. It is considered to be legal by most countries, but only in the case that it does not harm the company and its profit making in any way. The insider traders are mostly the officers, key employees, directors and other shareholders who may gain such authentic information. But this very term, insider trading, also have negative connotations. In the United States, it is incumbent upon the inside traders to publicly declare their trade transactions to the regulatory authority within the given time of business days. However, when the same thing is done based on material nonpublic information while an insider is carrying a duty, it becomes a fraud and a breach of trust. This illegal insider trading, which as a result raises the cost of capital for security issuers lead to a large decline in ec onomic growth. There are ethics officers, who are commonly known as business conduct officers, hired by organizations to protect their interests (Geisst, 2006). â€Å"Wall Street insider trading scandal 1980†: This practice has started since the mid-1980s due to constant series of financial frauds, corruption and many abuse scandals which surrounded the US defense industry. To protect and promote the ethical business practices the Defense Industry Initiative (DII) was formed, which set an initial standard for ethics management in companies. One such famous case of an insider trading scandal is that of â€Å"the Wall Street insider trading scandal of the mid-1980s†. Its primary player was Dennis Levine who was a managing director at Drexel Burnham Lambert (Newsweek, 1986). The initial charge was filed by the US Attorney Rudy Giuliani which finally led the investigators to arrest Ivan Boesky. Levine built a whole network of professionals in many Wall Street firms who wer e engaged in insider trading. He maintained an account with a fake name in the Swiss banks subsidiaries in Bahamas because it has some of the hardest bank secrecy laws as compared to anywhere in the world. He did this to be safe from detection. He then had to shift his business in May 1980 to â€Å"Bank Leu† which earned him around $10.6 million (Stewart, 1991). But at Bank Leu, the officials there realized Levine’s insider trading activities and banked on him themselves. But they did this collaborative action through Merrill Lynch, which detected a suspicion about trading activities in two other brokers’ personal accounts in May 1985. This started an internal investigation which reached Bank Leu, where due to the bank’s secrecy they had to forward the matter to the SEC â€Å"U.S. Securities and Exchange Commission†. It was decided by the bank officials that Levine should give his reasons for such an insider trading, but due to their destroying mos t of the sensitive documents relevant to Levine’s activity, they were charged with obstruction of justice (Dentzer, 1986). The Bank Leu officials decided to cooperate with the SEC because they noticed a huge gap between the actual managed accounts’ statements and the omnibus records. The stock trading was taken to be distinct from normal banking transactions and hence the bank named Levine guilty as the allegations were proved against him, thus his fraudulent activities led to his arrest. There was a tremendous amount of evidence against Levine related to securities fraud, obstructing justice, tax evasion and a charge of perjury as well. Levine decided to coordinate with the government in order to disclose the names of others who were involved alongside him (Levine and Hofer, 1991). This coordination with the government helped him to have a reduced sentence of two years in prison with a $362,000 fine (Time Magazine, 1987). He also agreed to pay the penalty for these il legal profits as well and also approved of

Statistical Reasoning in public Health Math Problem

Statistical Reasoning in public Health - Math Problem Example The children were followed for one year after randomization, and monitored for AOM during this period. 262 children were randomized to the vaccine group, and 150 of these children experienced at least one incident of AOM during the follow-up period. 134 children were randomized to the placebo group, and 83 of these children experience at least one incident of AOM during the follow-up period. (a) Report a 95% confidence interval for the proportion of children experiencing at least one incident of AOM during the follow-up period in: 1) the group randomized to receive AOM 51.2% to 63.1% 2) the group randomized to receive a placebo 53.5% to 69.7% 3) How do these 95% CI’s compare? (similar range of values? Overlap?) There is an overlap of values. (b) 1) Report a 95% confidence interval for the difference in proportions of children experiencing AOM over the follow-up period.

Ethical decisions and informed consent Essay Example for Free

Ethical decisions and informed consent Essay In all counseling programs meant for children and adolescents, it is very important that the parents be involved. The parents would require knowing the results of the psychological analysis, most probably in concern for the well being of their wards. However, in certain cases, the children or the adolescents might not intent the parents to know the details of their case. Like an adult patient, the child patient would want to ensure confidentiality of their case. However, it is also important to know that the child would not be in a position to make a proper decision regarding their treatment. Hence, it is very important to ensure that confidentiality exists to a limited extent in such cases. The counselors would have to protect the adolescent and the teenager regarding the individual case. They have to maintain strict confidentiality and should not inform anybody about the details of their case. However, the counselor would also have to inform the parent, as the parents are in the best position in making a valuable decision about their wards. The child or adolescent may be acting out of immaturity in these cases. It is also important to keep in mind that issues regarding the sexual activity of the child and the interventions required for the treatment of a sexually transmitted disease differs from one state to another. Certain issues such as abuse, neglect, presence of any risk or danger to others, etc, have to be reported to the parents. The counselor should be aware that the parents have rights of the children. Only the relevant information has to be disclosed to the parents so that they can make an informed decision for the welfare of their wards. The information presented should be accurate and comprehensive. In this case the parents would have to be informed if any case of neglect, abuse, harm to the child, etc is present. Treatment of a sexually transmitted disease may have to be reported in case the child may cause the risk of transmitting it to other people. The counselor should also try to determine if any danger is present for the 15-year-old client from any other party. If any such danger were present, the counselor would have to ensure that the child is adequately protected by informing the parents. In all cases, the counselor, to determine the need for informing the parents, should conduct a thorough assessment of the situation.

Sounding the Oirish: OBrien versus Synge :: Essays Papers

Sounding the Oirish: O'Brien versus Synge "Synge was perhaps the most monstrous phony and buffeon ever to enter our celtic toilet, but he won international fame and money because foreigners extracted strange meanings and nuances from the language he used." Flann O'Brien was a writer obsessed with both nationhood and language, and saw the two as inextricably entwined. Nowhere was this more apparent than in his writings under the pseudonym of Myles na Gopaleen. One particular target of O'Brien's scorn was J. M. Synge's Playboy of the Western World. O'Brien felt that with the success of Synge's play, the stage-Irishman as he appeared in Dion Boucicault's works of the mid-1800s had become the prime symbol of Irishness (although, it may be argued, both Boucicault and Synge are putting forward a subversive version of the stage Irishman who had been a staple part of English drama for centuries). The main thrust of O'Brien's knife is this: "The set-up is this. These people turn angrily on the British and roar: 'How dare you insult us with your stage Irishman, a monkey-faced leering scoundrel in ragged knee-breeches and a tail coat, always drunk and threatening anybody in sight with his shillelagh? We can put together a far better stage Irishma n ourselves, thank you. The Irish Stage Irishman is the best in the world.'" The pig-in-the-kitchen image of Ireland was, as far as O'Brien was concerned, the main effect of the nationalistic firing of half-cocked muskets. Rather than subverting the English stage Irishman, Boucicault, Synge and their ilk merely augmented its dubious itinerary (I never said that the pro-subversion argument was a winning one). The crippling stroke O'Brien applies to Synge deals exclusively with language: "[T]he worst was Synge. Here we had a moneyed dilettante coming straight from Paris to study the peasants of Aran not knowing a syllable of their language, then coming back to pour forth a deluge of homemade jargon all over the Abbey stage ..." From such jargon has emerged such wondrous entertainments as Darby O'Gill and the Little People, The Quiet Man, and even the recent offerings Far and Away and Waking Ned (add to this truncated role of dishonour umpteen others, and don't forget that amadan in Braveheart). Although Synge may have had subversive intentions, the legacy such work has given us is not subversive at all. Instead it bedecks the politics of colonialism with praties, shillelaghs, and a bottle of the aul' poitin.

Easyinternetcafe Cafe Essay

This case report addresses the challenges to implement a new logistic system that if well implemented it can improve operations and can convert easyinternetcafe into a profitable company. EasyInternetCafe (eIC)is a chain of Internet cafes with stores in the UK, the USA, Holland, Belgium, France, Germany, Spain and Italy. eIC is part of the Easy Group, headed by the Greek entrepreneur Stelios Haji-Ioannou. The original business model is to build and operate on the principle of ‘economics of scale’ or Yield Management: most stores would be open 24 hours a day, 7 days a week, and each has an average of 350 PC’s. In 2003, with losses continuing to mount, eIc management has decided to radically revamp their operations. In order to eliminate the need for future investments in new stores, the strategy was changed. It has been decided to appoint franchisees for the new stores and also, if possible, for the existing legacy stores. According to the new strategy, the franchisee would be required to bear the costs of the property and the hardware. It was also decided to move from large stores to smaller stores with 20 to 30 PCs. The current logistic situation represents a bottleneck and it is one of the major causes for the ongoing losses at easyinternetcafe. After reviewing different logistics scenarios and providers, I strongly recommend taking a closer look to support the logistic alternative that Ingram Micro is proposing. If we do that, we could benefit in the warehousing, accounting and transportation areas, through all this areas, it will help us reduce the logistics costs and labour per new store, from almost to  £2,000.00 to  £1,357.00, this and the benefits mentioned before, will help us to achieve our overall objective of being a profitable company. This; will be the strategic perspe ctive that will be demonstrated throughout the report. Issue(s) Identification: 1. Yield Management does not work for every company. eIC’s first store opened in June 1999 opposite in London. Soon afterwards, it was quickly recognized that eIC’s yield management had certain characteristics that later affected the business model: elC was offering a highly perishable product: 1 hour of Internet access time, cannot be put in inventory, once that hour is gone, there is no way of reselling that hour of internet access time. Although stores are large, capacity is limited; Internet access demand varies, not only by time of day, day of week, but also across other time and seasonal horizons. Incremental costs are next to nothing: it doesn’t matter whether there is one person or 500 in a store, the bandwidth is already there. By the time the second and third stores were opened, eIC had built yield management into its store management system. 2. Current Logistics System Logistics is not a core competency at elC, but it has become one of the integral activities. Logistics for elc means to supply the new stores with their initial assests, including all of the furniture and PCs. This system is a drag on scalability, efficiency and a bottleneck for growth and the main reason for spiraling high cost and ongoing losses. Environmental and Root Cause Analysis: Aggressive use of yield management is a recognized and admired business model of Stelios. EasyJet was a profitable company after just a few years of operation. However, with EasyInternetCafe profits seem a long way off, the assumption that offering very low prices would increase the demand significantly lead to losses of  £80m- £100m from 199 to 2002. Below are some root causes of the symptoms above: * The stores are too large; economies of scale don’t materialize if occupancy is half empty. * Fixed costs were too high due to the quantity of Pcs per store. * Staff overheads were excessive. Assumptions: * Are there sufficient customers who want to use an internet cafe? To-day, most of the homes have internet access, and many others have (free) access at their place of work or at colleges or university. * Are the stores located in the right place to attract customers throughout the day and the whole week? Downtown cafes might attract business people needing to keep in touch, but many city centres are quiet in the evenings and at weekends. By mid-2001, with cash running out a drastic action was necessary: a franchising plan is being developed. It is important that every cafe looked the same, with common signage, furnishings and PCs. The time to sign a contract with a franchise is one week. If the franchisee did not already have space for the cafà ©, eIc would assist in recommendations with locations within 28 days. The broadband internet connection had to be installed by the local telecoms supplier within 28 days. Also they need to Desk installed within seven days. Server delivered and installed 2 days and PCs delivered and installed 2 days. CVM delivered and installed 1 day Signage delivered and installed 1 day. Chairs delivered and installed 1 day. Testing complete system 2 days and also Open for business within one day. So, how much time should it take to open the cafe once the contract is signed? From the predecessors plan we see that average duration of time for all activity. Under bellow we discuss about time of the contract are signed.

Four stages of the learning cycle Essay

During our final chapter, we discussed the four stages of the learning cycle. The four stages of transformational learning are as follows: recognizing a significant problem, confronting it intensely, finding a solution, then integrating a new perspective and a new set of assumptions into ones’ life pattern. I think that a lot of times people go through life not realizing when they have a problem. Therefore, acknowledging your problem is most definitely the first step in learning from it. When you realize that there is a problem, you must confront the problem head on to find a solution. Once you have found a solution, you need to incorporate it into your life. These four stages are important in any learning experience. The transformational experience that I will use for my example is very personal. I used to be in a very abusive marriage. My marriage was damaging to me as a person, and damaging to my children because it prohibited me from making anything of myself. I would always make excuses for my lack of productivity, stating that I couldn’t do anything with my life because my husband wouldn’t let me. Finally, in 2011, I realized that I was wasting my life. The only thing that my daughter was ever going to learn from me, was how to let someone else run there life and impact her choices. We would never have had a normal life! When I realized what I was doing to myself and to my kids, I knew that I had a significant problem. I confronted the problem, and I was very intense about it. I tried marriage counseling, personal counseling, and biblical counseling. I tried talking with my ex, and I sought advice from many people whom I really believed could help. After exhausting my resources, I knew that the only logical solution was to take my children out of the abusive situation and start from scratch. I chose to go first to the police for help, and then to battered women’s shelter. The women’s shelter helped us to move away and start over. I have now been away from him for a little over two years, and I am in my first healthy relationship. By integrating my new perception, I was able to go farther in the past year than I ever did in all of the years of my former relationship. I am now a business owner, I am in school, and I am getting married to a wonderful man who loves me and my children. My children now get to grow up in a loving family and a healthy environment. I am now able to say with confidence that I am doing my best to be an example for them. This was most definitely a transformational learning experience for me. I think that in my experience the main stage that applied in my life, was the integration stage. It is often easier to recognize a problem, and even to find a solution, than it is to follow through on change. Often times the follow through is not so simple. There were numerous times during that relationship where I knew the problem, and the solution was apparent, however I didn’t believe in myself to integrate the solution it into my life. I believe that truly integrating a new perspective, and changing your assumptions is a very difficult stage to master. I am glad that I was able to make it through that final stage, and to become the person I am today. I still have a long way to go, but I am proud to be so far from who I once was.

The Office of the American Presidency essays

The Office of the American Presidency essays The American Constitution is, without dispute, one of the most significant political achievements of western civilization. The authors of the Constitution expounded the philosophy of their own political world, while at the same time leaving a legacy to protect, guide, and shape their country throughout all of history. Although there are many interesting aspects to this very complex document, this paper focuses solely on how the Founding Fathers theoretically envisioned the office of the American Presidency. My approach is not to merely compile a list of presidential powers, as a cursory reading of the constitution provides this information; but to briefly explore why the office was necessary and what role the Founding Fathers intended that a chief executive would fulfill. The truth is that everyone was a little nervous at the idea of having a chief executive. The cause of this uneasiness isnt difficult to understand considering that America had just finished fighting for independence from a single executive in the person of the King of England. The reason a presidential office was written into the design of the Constitution, at all, was a matter of structural necessity. To understand the need for an executive we must first examine the theoretical foundation of the country itself. One of the founding fathers, the Father of the Constitution, James Madison, argued that American government should be modeled as a republic rather than a democracy. One reason for this distinction is that, In a democracy the people meet and exercise the government in person; in a republic they assemble and administer it by their representatives and agents. A democracy, consequently, must be confined to a small spot. A republic may extend over a large region. More importantly, Madison argued that a democracy would be ineffective because factions would quickly control the government, leaving no protections for the weaker parties ...

Invention of Polystyrene and Styrofoam

Invention of Polystyrene and Styrofoam Polystyrene is a strong plastic created from erethylene and benzine. It can be injected, extruded or blow molded. This makes it a very useful and versatile manufacturing material.   Most of us recognize polystyrene in the form of styrofoam used for beverage cups and packaging peanuts. However, polystyrene is also used as a building material, with electrical appliances (light switches and plates) and in other household items. Eduard Simon Hermann Staudinger Polymer Research Keystone/Stringer/Getty Images German apothecary Eduard Simon discovered polystyrene in 1839 when he isolated the substance from natural resin. However, he did not know what he had discovered.  It took another organic chemist named Hermann Staudinger to realize that Simons discovery, comprised of long chains of styrene molecules, was a plastic polymer. In 1922, Staudinger published his theories on polymers. They stated that natural rubbers were made up of long repetitive chains of monomers that gave rubber its elasticity. He went on to write that the materials manufactured by the thermal processing of styrene were similar to rubber. They were the high polymers, including polystyrene. In 1953, Staudinger won the Nobel Prize for Chemistry for his research. BASF Commercial Use of Polystyrene Badische Anilin Soda-Fabrik or BASF was founded in 1861. BASF has a long history of being innovative due to having invented synthetic coal tar dyes, ammonia, nitrogenous fertilizers as well as developing polystyrene, PVC, magnetic tape and synthetic rubber. In 1930, the scientists at BASF developed a way to commercially manufacture polystyrene. A company called I.G. Farben is often listed as the developer of polystyrene because BASF was under trust to I G. Farben in 1930. In 1937, the Dow Chemical company introduced polystyrene products to the U.S. market. What we commonly call styrofoam, is actually the most recognizable form of foam polystyrene packaging. Styrofoam is the trademark of the Dow Chemical Company while the technical name of the product is foamed polystyrene. Ray McIntire - Styrofoam Inventor Dow Chemical Company scientist  Ray McIntire invented foamed polystyrene aka Styrofoam. McIntire said his invention of foamed polystyrene was purely accidental. His invention came about as he was trying to find a flexible electrical insulator around the time of World War II. Polystyrene, which already had been invented, was a good insulator but too brittle. McIntire tried to make a new rubber-like polymer by combining styrene with a volatile liquid called isobutylene  under pressure. The result was a foam polystyrene with bubble and was 30 times lighter than regular polystyrene. The Dow Chemical Company introduced Styrofoam products to the United State in 1954. How Are Foamed Polystyrene or Styrofoam Products Made? Foamed polystyrene starts as small spherical beads that contain an expanding agent called hydrocarbon.The polystyrene beads are heated with steam. As the expanding agent boils, the beads soften and expand up to forty times their original size.The expanded beads are left to cool down before being heated again.
