The Shockingly Simple Change That Can Improve All of Your Relationships
The Shockingly Simple Change That Can Improve All of Your Relationships I was having a cup of coffee at the café a few blocks from my apartment when I noticed something that has become shockingly common nowadays. Seated a few tables from me was a young couple who seemed like they were out on a coffee date.Everything looked okay, but there was one problem. Both the guy and the lady were on their phones. They were not talking to each other. They were not even paying the slightest attention to each other.Each of them was deeply engrossed in their smartphones and the limitless world their smartphones gave them access to.The scenario with the couple at the café is not a solitary case. It has almost become a natural part of the modern world. Next time you are out in public, try looking around and you will see it everywhere.In cafés and restaurants, on buses and trains, in the park, at home, and anywhere else you look, you will find people paying more attention to their phones than to their surroundings and the other people around them.The smartphone has bec ome the most ubiquitous piece of technology in the modern world. It has also brought so much positive changes to our lives. Smartphones have put the whole world at our fingertips.They give us access to unlimited information. We can communicate, shop, send money, plan our schedules, take photos and videos, budget, and do a ton of other things through our smartphones. Despite all these benefits, smartphones also have their drawbacks. We have become addicted to our smartphones.According to this survey, almost half of Americans admit they cannot spend an entire day without access to their smartphones. Even as I was writing this article, I found my hand twitching towards my smartphone a number of times. This addiction to smartphones is having negative effects on several aspects of our lives, including our relationships.Smartphones were invented as a way of making it easier for people to communicate and keep in touch. Unfortunately, while they succeeded in making it easy for us to communi cate, they have reduced our ability to connect with each other on an emotional level.People have become obsessed with texting and social media as the main means of communication, which has in turn made communication a lot less personal. People are opting for text communication over face to face communication.Smartphones have also placed a lot of demand on our time and attention, which has in turn reduced the amount of time and attention we give to our relationships.Like the couple from the café, we spend more time on our phones than we do connecting with others, which is negatively affecting our relationships with others.YOU GIVE LESS ATTENTION TO OTHERSHave you ever been talking to someone, only to realize that they are only listening to you half-heartedly and giving you unconvincing nods while all their attention is directed at their phones? How did it make you feel?Using your phone during a conversation takes your attention from the conversation.You become less engaged in the co nversation, and the other person can actually tell that you are not listening to them. It shows that you donât give much importance to the conversation.On the other hand, by keeping your phone away during conversations, you are better able to concentrate on the conversation, engage with the other person and properly listen to what they are saying.The person you are conversing with will notice your energy and they will return the same energy to you and the conversation will become more interesting. According to a paper published in the Journal of Applied Social Psychology, people feel more negative towards a simulated conversation when they imagine that the other person is paying more attention to their smartphone.Another study published in Computers in Human Behavior found that conversations were less satisfying when one or all of the people in the conversation were texting during the conversation.YOU MISS THE OPPORTUNITY TO CONNECT ON A DEEPER LEVELToday, a lot of people prefer c ommunicating via text messages and social media compared to face to face or voice communication. A teenager today might opt to use Facebook to get in touch with his crush, when they actually go to the same school and see each other every day.People in their twenties and thirties are foregoing approaching people they like in real life and opting to use apps such as Tinder and OkCupid to find dates. This preoccupation with electronic communication is robbing us of the opportunity to connect with each other on a deeper and emotional level.Interaction between people is not limited to the words we say to each other. When interacting with other people face to face, we watch things such as their posture, their gestures, their facial expressions, their voice and intonation, and so on.These non-verbal cues tell us more than the person is saying with their words and give us a deeper and more emotional understanding of what the other person is saying. Gestures such as hugs, a pat on the back, a stroke on the arm, or simply holding hands allow us to feel closer to others.When we share a touch with others, our brains release a chemical known as oxytocin, which creates an emotional connection between us.When we rely solely on text communication, there is no way for us to communicate non-verbally. Communication becomes superficial since it has been reduced to words on a screen.The result is that there is less intimacy and emotional connection in our interactions, leading to weaker relationships.LEADS TO FEELINGS OF JEALOUSY AND NEGLECT IN ROMANTIC RELATIONSHIPSSmartphones are responsible for a lot of broken romantic relationships.According to a survey by psychologists from two US universities, 75% of women feel that smartphones are ruining their relationships. When you spend more time engaging with your phone than you do with your partner, it can make your partner feel like a third wheeler in the relationship.It appears like your phone is more important than your partner, le aving him or her feeling unappreciated and neglected.In some cases, your partner might even feel jealous and assume that you are cheating on them, since you give more attention to other people (those accessible through your phone) than you do to him or her. This can take a toll on the intimacy between the two of you and can even end up breaking the relationship.IT AFFECTS YOUR MOODYour smartphone can also negatively affect your mood and in extension your ability to relate with the people around you. Social media is one of the top activities that people engage in on their smartphones.At the same time, social media use has been shown to contribute to stress and depression, according to a study published in in the Clinical Psychological Science.Social media makes it easy for you to compare yourself to others, which can ruin your mood. For instance, seeing photos of your exâs wedding can ruin your mood when you are having a night out with friends, making it more difficult for you to e njoy the night.Sometimes, spending a lot of time on social media can act as a replacement for social contact, which makes it more difficult for you to be comfortable in social situations in real life.This can lead to isolation which reinforces your use of social media which in turn makes you more comfortable in social situations, creating a vicious cycle that undermines your ability to connect and interact with other people in real life.HOW TO DITCH YOUR PHONE AND IMPROVE ALL OF YOUR RELATIONSHIPSIt is clear that your smartphone is doing harm to your relationships in more ways than one. One shockingly simple thing you can do to improve all your relationships, therefore, is to ditch your phone.Keep it tucked away and you will definitely see and improvement in all your relationships with others â" your parents, your friends, your colleagues, and your romantic partners.Unfortunately, keeping away your smartphone is not that easy. We are constantly reaching for it to check for notifica tions. Sometimes, reaching for your pocket and not feeling your phone almost triggers a mini heart attack.So, how do you keep it away to ensure that it does not affect your relationships? Below are some smartphone rules you should follow to prevent the gadget from getting in the way of your relationships.Avoid Using Your Phone In Social SituationsIgnoring other people in favor of paying attention to your phone has become so common that there is even a name for it â" âphubbingâ.This term was introduced as an attempt to push back against the social consequences of people paying more attention to their phones than to the people around them. Using your phone during a social situation does not just affect the people around you. It also affects you.According to this study, people who are constantly on their phones during a dinner date with friends are more likely to get bored and enjoy the dinner less compared to those who keep their phones away.Despite this, people still use their p hones during social interactions. According to this study, 89% of smartphone users were on their phone at least once during their most recent social interaction.If you want to keep the interaction interesting and enjoyable both for yourself and for those around you, you should avoid using your phone in social situations.When you find yourself in a situation where you will be interacting with others â" having dinner with family, sitting for some drinks with friends, chatting with colleagues at work, on a romantic date, and anywhere else â" you should avoid using your phone.Talk Now, Text LaterOne of the advantages of smartphones is that they made everything available instantaneously and on-demand. That friend who is in a different country? You can reach him instantly through a WhatsApp message.Seen something funny?You can share it with the world instantly.They basically allow us to be connected to the world from anywhere, at any time. On the flip side, this also means that people h ave access to us anytime, regardless of where we are, through texts, emails, tweets and so on.Your boss can send a work email when you are on a romantic date with your spouse and distract you from the moment. The key to making sure that the texts and emails donât distract you is to remind yourself that you can always reply to them later.Focus on enjoying the current moment with the people who are physically present. Give them your complete attention. People wonât die because you replied to their text or email an hour later.But wait, what if there is an emergency? If it was an emergency, donât you think the person would have called instead of sending an email or a text?Keep Your Phone Out Of Sight During Important ConversationsSometimes, avoiding using your phone during a conversation is not enough. You should keep it completely out of sight. Having your phone where you can see it can be highly distracting, making it difficult for you to give your undivided attention.Seeing you r phone stirs thoughts about the things that might be happening in the world accessible through your phone. You might remember the photo you posted on Instagram. How many likes has it gotten so far?How about the witty tweet you sent an hour ago? How have people reacted to it? These thoughts end up taking your mind away from the interaction.All this is not mere speculation.According to this study, the mere presence of a phone affects the quality of a conversation, even if no one is using the phone. It makes the relationship between the people in the conversation less empathetic and trustworthy.Therefore, the next time you need to have an important conversation with someone, remember to keep your phone out of sight.Experience Before UploadingThe age-old religious ritual of saying grace before a meal has been replaced by a new ritual â" taking photos of the meal.How many times have you seen millennials taking photos of their meal and posting them on Instagram before they start enjoyin g the meal?How many times have you seen people go to a soccer game or a music concert and spend the whole time viewing the action through the screens of their phones?Our preoccupation with smartphones and social media has made it much more difficult for us to enjoy experiences. Before having a meal, people want to show others on social media what they are having. If their social media followers donât like the meal, you can bet that the meal wonât be enjoyable.People go out on vacations with their significant others, but instead of enjoying the moment, they are only concerned with getting the right photo for social media.How would it make you feel if you took someone for dinner, but they end up not enjoying it because someone on social media didnât like what they ordered? Would you be interested in taking them out again?If you want to improve the quality of your relationships, you should be more focused on enjoying the moment and the experience and less focused on sharing the e xperience with others.Before sharing the meal with your followers, take the time to enjoy the meal and the company of whoever you are sharing the meal with. Before taking a photo and uploading it to show your followers the awesome scenery, take a moment to enjoy the scenery with whoever is right there with you.Avoid Searching For Everything On Your PhoneIn todayâs world of search engines, Google maps and review websites, all the information we need is available with a few clicks.This has made people more dependent on their smartphones than on other people, which has in turn led to decreased social interactions and connections.According to this study, people with a smartphone were more likely to depend on the phone for directions rather than asking others for help.The fact that all the information you need is available through your phone does not mean that you have to rely on your phone every time. Instead of checking review websites to find the best restaurant for a romantic date, ask your friend or colleague to recommend a nice hotel.Instead of checking online to find the best attractions in a city you are planning to visit, ask the friend who visited the city last year for recommendations.By turning to people for help instead of always searching for everything on your phone, you will increase the frequency of your interactions with people and see an improvement in the quality of your relationships with them.Keep Your Phone Away From Your BedroomThe addiction to our phones means that we always have them near us, including when we go to bed. According to a poll by Gallup, 63% of Americans sleep with their phones tucked beneath their pillows or within an armâs reach from bed.This might seem like a great convenience, since the phone acts as an alarm for some, and also allows you to check your social media for a last time before you sleep or catch up on your mail when you wake up in the morning.Unbeknownst to you, your phone might also be the culprit for the dying romance between you and your partner. If you spend most of your time in bed fiddling with your phone, you will naturally spend less time fiddling with your partner.According to a survey by Harris Interactive, 20% of young adults between the ages of 18 â" 34 use their phones during sex. How do you even do that?Carrying your phone to bed is not a great idea. Even if you donât end up using it while getting intimate with your partner, it reduces the chances of seeing any action. If this becomes a habit, it can negatively affect the quality of your relationship.Therefore, if you want to see an improvement in your relationship with your partner, you should consider making your bedroom a phone-free zone.This way, you will have more time to talk and bond with your partner.Have Phone Free DaysThis course of action might seem a bit extreme, and to many, it might be quite challenging. Whenever you receive a notification that someone has liked your status, retweeted you post or replied to your message, your brain releases the chemical dopamine, causing you to feel a sense of pleasure.This chemical reaction is what causes the addiction to your smartphone.When you keep glancing at your smartphone to check for notifications, your brain is essentially craving for a dose of dopamine. This is what makes keeping your phone away so difficult. While it might be challenging, having phone free days can help you break your addiction to your phone.Leave your phone at home for a day and spend the day interacting with people face to face or through your office telephone.Doing this will help you enhance the connection with your friends and colleagues (they will appreciate that you went to talk to them face to face) while at the same time helping you break your smartphone addiction.WRAPPING UPIf you are addicted to your smartphone, it might be negatively affecting your relationships, even though you might not have noticed it.Spending excessive time on your smartphone causes you t o give less attention to people around you, denies you the opportunity to connect with others on a deeper level, leads to feelings of jealousy and neglect in romantic relationships and affects your moods, which in turn affects how you relate to those around you.The key to improving your relationships, therefore, is to ditch your phone.You can do this by adhering to the smartphone rules shared above, such as not using your phone in social situations, replying to texts and emails later, keeping your phone out of sight during important conversations, taking the time to enjoy the moment before sharing with your social media followers, asking others for help instead of searching for everything on your phone, keeping your phone away from your bedroom, or even opting to have some phone-free days.

How to Write a Paper on Global Warming
How to Write a Paper on Global Warming Writing a paper on global warming can be rather tricky task, as a lot of specific information is needed and certain peculiarities exist. We propose to your consideration an exemplary paper on this topic so as you can analyze it and write your own one on its basis. Nature and climate are in the constant evolution and change. In the majority of cases this transformation process is significantly slower, than the life expectancy of the generation. Therefore, we cannot evidence and observe how nature around us is evolving, unless we specifically address related literature and tools that help us to do so. It used to be this way till very recent past, but, more and more during the last decade we hear about the phenomena of global warming and its effects on our life. A lot of literature and TV programs introduce us in the latest changes in global climate and nature transformation, such as melting ice of the South and North Poles, average sea water level increase globally, etc. All these events are the causes for extinction of the various species and significant change in the geographical layout of particular areas. Temperature records are becoming common in different places of the world: Brazil is suffering from extreme winter, Russia is diving in high summer temperature and droughts, while Europe is drawing in everlasting rains. All these changes happened during five to ten years. For the first time in our planetââ¬â¢s history the humanity can evidence rapid changes that can be seen and experienced by one generation in full. What are the consequences of the global warming and what should we expect in the nearest future? We are not in control of the nature, but we undoubtedly one of the strongest elements of nature cycle, as each and every human activity has it reflection in the nature. It is high time time to re-evaluate and re-analyse the role of the humans in todayââ¬â¢s environment and start turning our destructive activities into constructive cooperation.

Ethics And Morals Of Pi - 1181 Words
Mace 1 Megan Mace G. Cameron ENG 4U December 19, 2016 Ethics and Morals in Life of Pi Everybody; no matter your religion, skin colour, or gender possess a combination of morals based on the things internally believed are right or wrong. These can be established through many influences including, social constructs, personal experiences, and upbringing. Yann Martel is constantly challenging the readerââ¬â¢s morals throughout Life of Pi, after Pi is on the lifeboat, he has to make the extremely hard decision between his own religious morals, and survival. In all of Piââ¬â¢s dilemmas, survival always outweighs the ââ¬Å"needsâ⬠of mankind s culture, making these constructs no longer a priority.

Over many of years, the concept of utilitarianism has changed, people would once describe it as pain and pleasure. Now society begins to further the approach, thinking about the intensity and duration of pain and pleasure. To this day there are seven principles that should be considered while thinking about what true pain and pleasure are. Some including, intensity, duration, and propinquity or remoteness. Intensity, being one of the most important of all, can determine whether or not it is pain or pleasure, revealing a high degree of emotional excitement. The length of time something continues or exists, is known a duration. Propinquity or remoteness is the thinking of how close something is either in a time or location sense, as in when or where it is about to happen. These are all great morals to have, when itââ¬â¢s thought of in a utilitarian sense, it should be applied to a majority for itââ¬â¢s still the idea of equality.

The Future Of Fuel Cell Technology Engineering Essay Free Essays
In our current universe of planetary heating, clime alteration, fuel insecurity, and high energy demand and ingestion from developing states, it is perfectly necessary we started looking into how to bring forth the power of the hereafter. Through research, development, and promotion of engineering, several beginnings of alternate, clean renewable energy have been identified. One of the alternate beginnings of energy for the hereafter is ââ¬Å" The Fuel Cell Technology â⬠. We will write a custom essay sample on The Future Of Fuel Cell Technology Engineering Essay or any similar topic only for you Order Now This engineering ( fuel cell engineering ) has the possible to be the drift which will transform the manner in which industries of today will bring forth energy of tomorrow. Fuel Cell can merely be describe as a power bring forthing system made up of electrochemical cell that converts the chemical energy of H into electrical energy. The electrical energy is generated from the reaction between H ( which is the fuel ) an O ( which is the oxidizer ) . The history of fuel cells history can be dated back to 1939 when William Grove, a British scientist foremost discovered its rule. He demonstrated this by utilizing four big cells ( each incorporating H and O ) to bring forth electric power which was so used to divide the H2O ( in a smaller upper cell ) into H and O. The National Aeronautics and Space Administration ( NASA ) subsequently demonstrated their possible applications in supplying power during infinite flights. Since so, industry has been looking at the commercial viability of fuel cells engineering to bring forth energy in assorted applications in such a manner that it can vie with other sources/types of energy coevals. Fuel Cells Types There are several types of fuel cells being developed. The chief difference between fuel cells types is their electrolyte. The chief fuel cells types are listed below: Proton Exchange Membrane Fuel Cells ( PEMFC ) : This is besides called the Polymer Electrolyte Membrane Fuel Cell. It is the most favorable fuel cell engineering that offer alternate to the internal burning engine. The PEMFC uses a thin plastic membrane as its electrolyte. The reaction gases ( H and O ) are fed into the cell to respond with the anode and the cathode. The fuel H continuously flows to the anode. At the anode, H ions ( or protons ) and negatrons are produce from the H. Merely positively charged H ions pass through the membrane. The negatively charged negatrons flow to the electrical socket to bring forth electrical power. Oxygen continuously flow to the cathode. At the cathode the O combines with H ions and the negatrons to organize H2O which flows out of the cell. 2HA? a 4Ha + 4ea?à » Equation for the reaction of the anode Oaââ¬Å¡Ã¢â¬Å¡ + 4Ha + 4ea?à » a 2Haââ¬Å¡Ã¢â¬Å¡O Equation for the reaction at the cathode 2Haââ¬Å¡Ã¢â¬Å¡ + Oaââ¬Å¡Ã¢â¬Å¡ a 2Haââ¬Å¡Ã¢â¬Å¡O Overall Equation Figure 1: How PEMFC works ( Beginning: hypertext transfer protocol: //altenergystation.com/fuel-cells.html ) The PEMFC has many advantages over all other types of fuel cell ; The PEMFC has a high power denseness and a low operating temperature ( of about 60-80 grades Celsius ) compared with other types of fuel cell. Its low operating temperature makes the fuel cell to warm up and get down bring forthing electricity within a short period of clip. Besides, the electrolyte is a solid stuff which makes it simpler to fabricate. The solid electrolyte of PEMFC makes it easier to orientate compared with other electrolytes. It is besides less caustic and has longer cell life and stack life. Other advantages of PEMFC are: It merely requires H and O as reactant. The by merchandise is H2O. It can be used as an option to internal burning engine. Although PEMFC has many benefits, it does hold some disadvantages excessively. The operating temperature is low ( about 80Aà °C ) ; which is non high plenty to execute utile cogeneration. It is an expensive signifier of electricity coevals. It cost about ?2500 ââ¬â ?5000 per kilowatt. The control of wet in the cathode and anode watercourse is of import as the electrolyte is required to be saturated with H2O to run optimally. Direct Methanol Fuel Cells ( DMFC ) These types of fuel cells are comparable to the PEMFC except that methyl alcohol is used as fuel alternatively of H. It works by oxidising of the liquid methyl alcohol ( CHaââ¬Å¡?OH ) in the presence of H2O at the anode. The DMFC uses the same type of electrolyte as the PEMFC, but with thicker membranes. The chemical equation ( reaction ) of the DMFC is as follow ; At the anode: CHaââ¬Å¡?OH + Haââ¬Å¡Ã¢â¬Å¡O a COaââ¬Å¡Ã¢â¬Å¡ +6Ha + 6ea?à » At the cathode: 3/2Oaââ¬Å¡Ã¢â¬Å¡ + 6Ha + 6ea?à » a 3Haââ¬Å¡Ã¢â¬Å¡O Overall Equation: CHaââ¬Å¡?OH + 3/2Oaââ¬Å¡Ã¢â¬Å¡ a COaââ¬Å¡Ã¢â¬Å¡+ 2Haââ¬Å¡Ã¢â¬Å¡O DMFC engineering is really applicable for portable power devices like laptops, 2-way wirelesss, cell phones, PDA etc. This is due to the high energy denseness of the methyl alcohol fuel. The current DMFCs can bring forth power denseness between 300-1000mWcmA? compared to PEMFC power denseness of 300-1000mWcmA? . DMFC can run between 50Aà °C and 120Aà °C with an efficiency of approximately 40 % . The DMFC offers a batch of benefits compared with PEMFC ; nevertheless its development is still in its early phases. Some of its advantages are ; It uses a liquid ( methyl alcohol ) fuel for power. Methanol can incorporate efficaciously with transmittal and distribution systems that are already in being. It does non necessitate a complicated fuel storage system, as suppose to hydrogen fuel storage for PEMFC. It is simpler in its design, and has the possible for low-volume, lightweight packaging. Methanol is easier to transport and provide in commercial measures utilizing current gasolene substructure. The chief disadvantage nevertheless, is that the low oxidation of methyl alcohol to hydrogen ions and COaââ¬Å¡Ã¢â¬Å¡ requires a more active accelerator. The fuel stack requires big measures of Pt compared with the PEMFC. Due to the big measures of Pt requires, the DMFC are more expensive. Other disadvantages are ; methanol is extremely caustic and toxic, DMFC have low efficiency compared to PEMFC due to the high pervasion of methyl alcohol through the membrane. Alkaline Fuel Cells ( AFC ) AFC were one of the first type of fuel cell engineerings developed and used in the United States infinite plan to bring forth electricity. AFC operates by utilizing a solution of K hydrated oxide ( KOH ) in H2O as the electrolyte. It can utilize a broad scope of assorted non-precious metals as a accelerator at the anode and the cathode. AFC operates at temperature between 100Aà °C and 250Aà °C, nevertheless, most recent design of AFC operate at lower temperature of approximately 23Aà °C to 70Aà °C. AFC have been proved to hold efficiency of stopping point to 60 % . Advantages of AFC are ; The costs of AFC are lowered compared to other signifiers of fuel cell engineerings because Alkaline engineering can work absolutely good without the usage of cherished metals. The AFC operates at a low temperature of about 70Aà °C. This lower its costs because the lower the operating temperature, the lower the cost of the stuffs needed to make a working and dependable system. AFC has the highest efficiency of all fuel cell type ( about 60 % ) . AFC nevertheless is susceptible to taint, hence requires pure H and O. Susceptibility of AFCs to taint besides affects the cell ââ¬Ës life-time, therefore extra cost. Phosphoric Acid Fuel Cells ( PAFC ) The PAFC is one of the modern fuel cell and the first to be used commercially. PAFC can bring forth up to 200 kilowatt of power and is chiefly used to power stationary power coevals and besides to power big vehicles like coachs. The PAFC uses liquid phosphorous acid as an electrolyte. The phosphorous acid is contained in a Teflon-bonded Si carbide matrix and porous C electrodes incorporating a Pt accelerator. The chief feature of PAFC is the impregnation of the phosphorous acid aqueous solution as the electrolyte in the matrix. The efficiency of PAFC is approximately 40 % but can be increased to over 70 % with combined heat and power. One of the chief advantages of PAFC is that they are more receptive to drosss in fossil fuels that have been reformed into H than PEMFC, which are easy poisoned by C monoxide. PAFC are besides more efficient when used for the cogeneration of electricity and heat ( about 85 % ) . Other benefit of PAFC is its first-class dependability and long-run public presentation. The disadvantage nevertheless is that it takes longer to warm up because it operates at a higher temperature ( between 150Aà °C and 200Aà °C ) , therefore doing it unsuitable for usage in autos. It besides requires Pt as a accelerator like most other types of fuel cells, but provides low power and current.

Romeo And Juliet Essays (946 words) - Characters In Romeo And Juliet
Romeo And Juliet Romeo and Juliet, said to be one of the most famous love stories of all times, is a play anchored on time and fate. Some actions are believed to occur by chance or by destiny. The timing of each action influences the outcome of the play. While some events are of less significance, some are crucial to the development of this tragedy. The substantial events that inspire the conclusion of Romeo and Juliet are; the Capulet ball, the quarrel experienced by Tybalt and Romeo, and Friar Johns plague. A servant to Capulet, who is incapable of reading the list of guests, asks for Romeos assistance. Romeo notices that Rosaline, his lover, is among these names. Benvolio challenges Romeo to compare her with other beauties. Benvolio predicts, Compare her face with some that I shall show,/ And I will make thee think thy swan a crow. (I, ii, l 86-87) To show his appreciation, the servant asks for Romeos presence at the ball. Romeo should have considered the servants warning; if Romeo occupies the name of Montague, he shall not be permitted. Once at the ball, Romeo is searching for a maiden to substitute the unrequited love of Rosaline. Romeo happens to gaze upon Juliet, who charms Romeo. Romeo proclaims, Did my heart love till now? Forswear it, sight!/ For neer saw true beauty till this night. (I, v, l 52-53) Since Romeo declares his love for Juliet, she feels the attraction also. They believe that they are in love and must marry. However, it is a genuine coincidence that Romeo and Juliet were at the same place, at the same time. Some days after the ball, Benvolio and Mercutio are conversing, in regard to the quarrelsome weather. Benvolio declares, The day is hot, the Capulets abroad,/ And if we meet we shall not scape a brawl,/ For now these got days is the mad blood stirring. (III, i, l 2-4) At this point, Tybalt, who has challenged Romeo because of his appearance at the masquerade, enters, seeking Romeo. On Romeos behalf, Mercutio struggles with Tybalt, while Romeo, who is filled with love for his new cousin, tries to end their boldness. Before escaping, Tybalt plunges his sword into Mercutio, causing death to fall upon him. Mercutio blames Romeo and the feud for his fate. Romeo kills Tybalt, who taunts Romeo, upon his return. Romeo fears he will be condemned to death if he does not flee before the arrival of the Prince. Benvolio recalls the events that have happened, with some embellishment. The Prince declares: And for that offence/ Immediately we do exile him hence./ I hav an in your hates proceeding,/ My blood for your rude brawls doth lie a-bleeding;/ But Ill amerce you with so strong a fine/ That you shall repent the loss of mine./ I will be deaf to pleading and excuses;/ Nor tears nor prayers shall purchase out abuses;/ Therefore use none. Let Romeo hence in haste,/ Else, when hes found, that hour is his last./ Bear hence this body and attend our will./ Mercy but murders, pardoning those that kill. (III, i, l 185-195) Due to the disturbance of Veronas street and the losses of Tybalt and Mercutio, the Prince must penalize Romeo. However, the Prince agrees that Romeo was acting in self defense. Juliet, who desires not to wed Paris, asks for Friar Laurences assistance. The day before the wedding, Juliet is to drink the poison, which will make her appear to be dead. In forty two hours she shall awake, with Romeo by her side. Romeo will then bring her to Mantua with him. In the meantime Friar Laurence will convey a message to Romeo in Mantua, telling him the plot. When she gains consciousness, Romeo and Friar Laurence will be there. Friar Laurence says, Shall Romeo by my letters know our drift,/ And hither shall he come; and he and I/ Will watch thy waking (IV, i, l 114-116) Following Juliets intake of the poison, Romeo is anticipating news from Verona. Balthasar, a servant to Romeo, tells Romeo that Juliet has passed on. Romeo, who is told there are no letters from the friar, seeks a way to accomplish his

Anton Chekhov - Biography and Profile
Anton Chekhov - Biography and Profile Born in 1860, Anton Chekhov grew up in the Russian town of Taganrog. He spent much of his childhood quietly sitting in his fathers fledgling grocery store. He watched the customers and listened to the their gossip, their hopes, and their complaints. Early on, he learned to observe the everyday lives of humans. His ability to listen would become one of his most valuable skills as a storyteller. Chekhovs YouthHis father, Paul Chekhov, grew up in an impoverished family. Antons grandfather was actually a serf in Czarist Russia, but through hard work and thriftiness, he purchased his familys freedom. Young Antons father became a self-employed grocer, but the business never prospered and eventually fell apart. Monetary woes dominated Chekhovs childhood. As a result, financial conflicts are prominent in his plays and fiction. Despite economic hardship, Chekhov was a talented student. In 1879, he left Taganrog to attend medical school in Moscow. At this time, he felt the pressure of being the head of the household. His father was no longer earning a living. Chekhov needed a way to make money without abandoning school. Writing stories provided a solution. He began writing humorous stories for local newspapers and journals. At first the stories paid very little. However, Chekhov was a quick and prolific humorist. By the time he was in his forth year of medical school, he had caught the attention of several editors. By 1883, his stories were earning him not only money but notoriety. Chekhovs Literary PurposeAs a writer, Chekhov did not subscribe to a particular religion or political affiliation. He wanted to satirize not preach. At the time, artists and scholars debated the purpose of literature. Some felt that literature should offer life instructions. Others felt that art should simply exist to please. For the most part, Chekhov agreed with the latter view. The artist must be, not the judge of his characters and of what they say, but merely a dispassionate observer. Anton Chekhov Chekhov the PlaywrightBecause of his fondness for dialogue, Chekhov felt drawn to the theatre. His early plays such as Ivanov and The Wood Demon artistically dissatisfied him. In 1895 he began working on a rather original theatrical project: The Seagull. It was a play that defied many of the traditional elements of common stage productions. It lacked plot and it focused on many interesting yet emotionally static characters. In 1896 The Seagull received a disastrous response on opening night. The audience actually booed during the first act. Fortunately, innovative directors Konstantin Stanislavski and Vladimir Nemirovich-Danechenko believed in Chekhovs work. Their new approach to drama invigorated audiences. The Moscow Art Theatre restaged The Seagull and created a triumphant crowd-pleaser. Soon after, the Moscow Art Theatre, led by Stanislavski and Nemirovich-Danechenko, produced the rest of Chekhovs masterpieces: Uncle Vanya (1899) The Three Sisters (1900) The Cherry Orchard (1904) Chekhovs Love LifeThe Russian storyteller played with themes of romance and marriage, but throughout most of his life he did not take love seriously. He had occasional affairs, but he did not fall in love until he met Olga Knipper, an up-and-coming Russian actress. They were very discreetly married in 1901. Olga not only starred in Chekhovs plays, she also deeply understood them. More than anyone in Chekhovs circle, she interpreted the subtle meanings within the plays. For example, Stanislavski thought The Cherry Orchard was a tragedy of Russian life. Olga instead knew that Chekhov intended it to be a gay comedy, one that almost touched upon farce. Olga and Chekhov were kindred spirits, though they did not spend much time together. Their letters indicate that they were very affectionate to one another. Sadly, their marriage would not last very long, due to Chekhovs failing health. Chekhovs Final DaysAt the age of 24, Chekhov began showing signs of tuberculosis. He tried to ignore this condition; however by his early 30s his health had deterorated beyond denial. When The Cherry Orchard opened in 1904, tuberculosis had ravaged his lungs. His body was visibly weakened. Most of his friends and family knew the end was near. Opening night of The Cherry Orchard became a tribute filled with speeches and heartfelt thanks. It was their was of saying goodbye to Russias greatest playwright. On July 14th, 1904, Chekhov stayed up late working on yet another short story. After going to bed, he suddenly awoke and summoned a doctor. The physician could do nothing for him but offer a glass of champagne. Reportedly, his final words were, Its a long time since I drank champagne. Then, after drinking the beverage, he died Chekhovs LegacyDuring and after his lifetime, Anton Chekhov was adored throughout Russia. Aside from his beloved stories and plays, he is also remembered as a humanitarian and a philanthropist. While living in the country, he often attended to the medical needs of the local peasants. Also, he was renowned for sponsoring local writers and medical students. His literary work has been embraced throughout the world. While many playwrights create intense, life-or-death scenarios, Chekhovs plays offer everyday conversations. Readers cherish his extraordinary insight into the lives of the ordinary.

Hurricane Etymology
Hurricane Etymology Unlike most words that Spanish and English share because of their shared history with Latin, hurricane came to English directly from Spanish, where it is currently spelled huracn. But Spanish explorers and conquerers first picked up the word from Taino, an Arawak language from the Caribbean. According to most authorities, the Taino word huracan meant simply storm, although some less reliable sources indicate that it also referred to a storm god or an evil spirit. This word was a natural one for the Spanish explorers and conquerors to pick up from the indigenous population, since winds as strong as the hurricanes of the Caribbean were an unusual weather phenomenon for them. Use of ââ¬ËHurricaneââ¬â¢ and Huracn The fact that the Spaniards introduced the word to the English language is the reason that our word hurricane generally refers to tropical cyclones that have their origin in the Caribbean or Atlantic. When the same type of storm has its origin in the Pacific, it is known as a typhoon (originally a Greek word), orà tifà ³nà in Spanish. There is a slight difference in the way the storms are categorized in the languages, however. In Spanish, aà tifà ³nà generally is considered to be aà huracnà that forms in the Pacific, while in English hurricane and typhoon are considered to be separate types of storms, even though the only difference is where they form. In both languages, the word can be used to refer figuratively to anything that is powerful and causes turmoil. In Spanish,à huracnà can also be used to refer to a particularly impetuous person. At the time the Spanish language adopted this word, the h was pronounced (it is silent now) and was sometimes used interchangeably with f. So the same word in Portuguese became furaco, and in the late 1500s the English word was sometimes spelled forcane. Numerous other spellings were used until the word was firmly established at the end of the 16th century; Shakespeare used the spelling of hurricano to refer to a waterspout. The word huracn is not capitalizedà when referring to named storms. It is used as in this sentence: El huracn Ana trajo lluvias intensas. (Hurricane Ana brought heavy rains.) Other Spanish Weather Terms in English Hurricane isnt the only Spanish weather term that has found its way into English. The most common of them, tornado, is especially interesting because of the way the two languages played off each other. The Strange Story of ââ¬ËTornadoââ¬â¢ and Tornado Although English got its word tornado from Spanish, Spanish surprisingly got its word tornado from English. Thats because the Spanish word that English borrowed wasnt tornado but tronada, a word for a thunderstorm. As is common in etymology, words often change form when imported into another language. According to the Online Etymology Dictionary, the change of -ro- to -or- was influenced by the spelling of tornar, a Spanish verb meaning to turn. Although tornado in English originally referred to various types of whirlwinds or rotary storms, including hurricanes, in the United States the word eventually came to refer primarily to a type of funneled windstorm common in the U.S. Midwest. In modern Spanish, tornado, borrowed from English, can still refer to various kinds of storms and whirlwinds, including hurricanes. A windstorm on the scale of a tornado, or smaller such as a whirlwind, can also be called a torbellino. Derecho Another type of storm phenomenon is known as a derecho, a direct borrowing of the Spanish derecho, which can, confusingly to foreigners, mean either right (as an adjective) or straight. In this context, it is the second meaning that matters. A derecho refers to a cluster of thunderstorms that travels in a straight line and is capable of causing great destruction. According to the Online Etymology Dictionary, Gustavus Hinrichs of the Iowa Weather Service started using the term in the late 1800s to avoid confusing a certain type of storm system with tornadoes. Key Takeaways The English word hurricane started out as an indigenous Caribbean terms that was adopted into Spanish and then spread to English via Spanish explorers and conquerors.Because the word hurricane came from the Caribbean, a different term is used for the same type of storm when occurring in the Pacific Ocean.The weather terms tornado and derecho also come from Spanish.
