Egyptair Flight 990-Informative Speech Essays - Brookhaven, New York
Egyptair Flight 990-Informative Speech Title: The Pilot or The Plane? General Purpose: To Inform Specific Purpose: To inform the audience of a plane crash that occurred a couple of weeks ago. I. Introduction A. (Attention Getter) Passengers on EgyptAir were beginning to get relaxed, take a quick nap, or drink a cup of coffee. All of a sudden, a big rumble on the plane occurs, passengers notice that their coffee mugs are beginning to spill, and their weight is beginning to be shifted. They then see that there overhead luggage is being tossed from their compartments to the other side of the plane. Everyone begins screaming, holding on to their seats, trying to buckle their seatbelts. As they look around, they see others being tossed around like a salad. They begin to feel weightless, they hear one last crash and then silence seizes the rest of their lives forever. B. (Reason to Listen) Flight 990 just recently went through this trauma and now that the black box was discovered, there are a few possibilities why the plane nose dived into the ocean in about twenty-eight seconds. Many people fly many different places everyday without knowing or thinking about what can happen up in the air, and with so many lives lost in plane crashes, there is no knowing which plane will be the next one. C. (Speaker Credibility) I have researched this article from Newsweek and have studied the pictures and diagrams thoroughly. I believe that with the information given, I am able to talk about this topic openly. D. (Thesis and Preview) Today I am going to speak about the significance of EgyptAir Flight 990, and the rapid descent that occurred that caused many lives to be lost. I will first talk about how the plane ended up 250 feet under the ocean, and second, I will speak about what happened to the pilots at the time of the descent and what could have occurred. II. Body A. Everything that occurred was noted on the black box, which tells in details what occurred in the cock pit of the plane. 1. The autopilot was disengaged deliberately by someone at 33,000 feet in then air. a. This something that is normally done when preparing to descend routinely or in case of an emergency. b. About 8 seconds after the autopilot was disengaged, someone made the plane face straight down with the ?nose? downward. c. Next, someone then decreased power in both of the two engines and then cut the power off completely. 2. There was no sign of trouble with the engines and no sign of why the engines were almost restarted. a. This could actually happen if the pilot was trying to restart the engine after dying, but there was no engine problems at the time. b. There was no call to air-traffic controllers to warn anyone about what was happening or if help was needed. Transition: With no warning to what was happening in the air, many conclusions are being considered. B. There are many thoughts to why the plane may have been positioned nose down and why the engines were shut off. 1. Some investigators think that this could have been a suicide attempt out of plain madness. 2. Other investigators along with some FBI think that there just have maybe been a struggle in the cockpit in the plane. 3. U.S. officials are working with the Egyptian government to ask family members and friends about the victims and as well as the pilots. Transition: With so many circumstances being considered, the FBI is being pushed away from investigations. C. The White House has declared that the FBI do not get too involved into the investigation until NTSB (National Transportation Safety Board) investigators are through with their searches. 1. The NTSB did not want to have another fiasco like that which happened with the TWA 800 flight. a. With the TWA 800 flight, the FBI suspected that the plane crash was due to terrorist bombs or missiles. b. The NTSB wanted the least publicity possible for flight 990. 2. FBI officials are now angry with NTSB officials for not allowing them to look into the crash. a. FBI has been shut out of the analyzing of the flight recorder. b. They have even been pushed away from the podium by the NTSB during a press conference. 3. The NTSB is not yet through searching the waters for more clues. a. They have not yet found all the pieces of the plane. b. It is guessed that the pieces missing can be no bigger than the back of a chair. III. Conclusion A. (Summary and

Social Categorization and Social Construction theory
Social Categorization and Social Construction theory Free Online Research Papers It is through social interactions that have put people to act and react implication to others. Due to the social interactions we learn what is acceptable and what is not. Over time these rules become internalised within us and eventually become an unconscious part of our lives and our identity. Social identity theory asserts that group membership creates in group self-categorisation and enhancement in ways that favour the in group at the expense of the out-group and associating with a group even under minimal circumstances is enough to create in group out-group hostility. I will explore the effects of the contact theory or intergroup behaviour. It is also the aim of this essay to explain what is meant by the term social construction and social categorisation and how these two theories have further to our understanding of identity. Social categorisation is viewed as a perception cognition or behaviour that is influenced by peoples recognition that day and other are members of distinct social groups. Relations between social groups can have far reaching and persuasive effects on the behaviour of member of these groups, effects that go well and beyond situations of face-to-face intergroup encounters. Social construction his used to describe how we as humans understand how the world is conscripted in and through social relations there are many different ways of understanding the same issue, rather than they had been an objective reality. Our behaviour is regulated by guidelines, which make everyday life predictable and understandable causing us to behave in a certain way the way that is seen as the norm. Housework provides a good example of the social construction being seen as the norm in Western societies many people thought that it was natural for women to be whipped rather than men to do all the housework. (Phoenix, 2002). It seemed natural because that was what usually happened and continued for as long as people remembered. The next sample of a construction was taken from natural because it had been the excepted pattern for a long time it wasnt until the feminist viewpoint argued for equality for women, that the idea was that it is not natural for women to do all the housework that another construction developed. Tajfel devised an intriguing paradigm to exploring the effects of intergroup behaviour using minimal effects (Tajfel, 1982). Two random groups of children were made, but allegedly on the basis of their express preference for paintings by two different artists. The children only knew the group table in with the identity of out-group and fellow in group members concealed. The result showed the children strongly favoured their own group they adopted the in group favouritism strategy despite such minimal effects and how this was created on the basis of a flimsy criteria. The robust finding from hundreds of minimal group experiments conducted is that the mere fact of being categorised as the group members seems to be necessary to produce ethnocentrism and competitive intra group behaviour. Social identity phenomena are motivated by two underlying processes self enhancement and uncertainty reduction. One of the key premises of the social identity approach is that group stand in status and pressed each relation to one another some groups are simply more prestigious and higher status than other. Jane Elliott, made a short movie called the eye of the storm, of a classroom demonstration in which he divided her class of very young children into those with blue and those with brown eyes. For one day the brown eyes, and then for one day the blue eyes were assigned inferior status, hence they were ridiculed, denied privileges. In a follow-up study of the students when they were 18, Elliot found that they reported themselves as being more tolerant of differences between groups and actively opposed to prejudice. Wright (1997) and his colleagues suggested that intergroup friendship between others if my friend John has close out group of friends then maybe the out-group isnt quite as bad as I thought. When people are separated they are likely to experienced hostility, resulting in failure to understand the reason for their actions. Lack of contact means theres no way of checking out interpretations of others. Bringing people into contact with each other should make them seem more familiar, and at least offer the possibility that negative cycle can be interrupted and even reversed. We have seen that by just allocating individuals to groups can create prejudice for and against individuals. Prejudice allow self-esteem to be enhanced by belonging to the positive group, creating hostility to others seen as inferior, for no reason other than that individuals are allocated social categories. Individuals also advocate themselves to a groups of higher social standing using social mobility e.g. through promotion in employment, leaving behind what was seen as being inferior. In social construction, language is a powerful tool, used to justify particular perspective, an example of the unused is that of (Potter and Wetherell,1987) which illustrates this whether we call someone a freedom fighter or a terrorist, the two terms can refer to the same person in each constructs a different way of viewing that person and the world. Social construction is an idea which may appear to be natural and obvious to those who accept it, but in reality it is an invention of a particular culture or society. The social constructionist approach allows us to change our identity throughout our lives, as Gergenââ¬â¢s did when he was forced to eventually to use a computer instead of a pen. As we have seen social constructionist is concerned with how we use categories to structure our experience of the world they believe that the way we understand the world are not natural, but are constructed between people in everyday social interactions, that identity is fluid and changing from one social situation to another. Social constructionist Kiwis reject the notion that people have one core identity that is the centre of who they are. Instead they suggest that people have many different identities, and that these are de-centred because they always operative in relation to other identities. We have seen that identities are not fixed, but are fluid, complex and diverse. There is the interrelationship between the social and personal identities which are constantly contradicting and competing, opening up opportunities for diversity. Individuals to have multiple identities which can do change throughout their life. People can often categorise themselves into different groups, they can choose to adopt their identities to the group they want to belong. People are constantly changing and adopting new identities to suit themselves, adapting and enhancing their self-esteem, which makes us uniquely human and different from other animals. Evidence has shown that contact and education causes people to recognise that they are in face a great deal more similar than they had initially thought which helps us better understand intergroup behaviours and ways of resolving a negative prototype perception of the out-group. Final word count ââ¬â 1065 References. * Open University Part two Scenario 1 Question 1 This study is not consistent with the guidelines. Whenever varies possible consent of the child has to be obtained. Parentsââ¬â¢ consent is required for disclosure of confidential information, and in this case the investigator must receive approval from ethics committee. Special safeguarding procedures are required with children. In United Kingdom a researcher requires a CRB. Children should be given as much opportunity is possible to be explained the nature, purpose and anticipated of taking part, and also be made aware of right to withdraw. Consent is to be asked throughout experiment not just in the beginning, children should feel comfortable. It is advised to refrain from research based upon observation of public behaviour to those situations in which persons being studied might expect to be it cant be said that children would think they would be as they are young. Question 2 In studying childrens play behaviour, it would be wise to contact a local preschool teacher and get consent approval not only from the teacher but also the parents and children, as well approval from ethics committee. Importantly a CRB would be required. After consent has been granted, and all parties have been briefed and given the okay to video record and observe the research would be carried out on a daily basis recording the children in their natural environment over a period of time. On a regular basis right to withdraw would be reminded, and an assurance that everybody is comfortable. The children would be recorded throughout the day whilst they are engaging in playtime to see how they interact with one another. In this environment if anything gets out of hand, the teacher is present and therefore the investigator does not need to get involved, or refrain from resulting in putting anybody in danger. Scenario 2 Question 1 She could have asked the group of people for their consent to participate in the experiment. Make them aware of the nature, purpose and anticipation and their right to withdraw. Keep an adequate record of when, and how and from whom consent was obtained. Ask if they wish to disclose their identity or remain anonymous. She should ask for permission to record the participants. Verify they are competent and are not under the age of 16 otherwise permission from a parent or guardian may be required. Question 2 The researcher might have to be careful if the participant has asked to remain anonymous and be careful whilst quoting as it may threaten to reveal their identity. Another reason might be that the participant never gave consent to be recorded and or quoted which is against the ethics as consent is required, or participant may have withdrawn therefore evidence needs to be destroyed. Question 3 The researcher could make a semi structured interview, and that includes eating disorder questions and other topics to prevent realisation. In this form they can try to find young students who would be willing to participate, and be told their opinion is required on various topics. They would be asked permission for audio recording, and quoting, also debriefed and told of their right to withdraw, and whether or not they like to remain anonymous. Perhaps once the data has been compiled they can be told of the full intentions of the experiment, as the specifics of finding opinions towards eating disorders, and then to be again asked whether or not they would like to withdraw, if they do so the data has to be destroyed. Scenario 3 Question 1 The most relevant is the ethical principle respect, because in this section it asked to respect cultural, religious, and race therefore that relates to the experiment as it is based on religious identity. It is an opinionated questionnaire and this ethics principal asked to respect participantââ¬â¢s knowledge, insight, experience and expertise. As this experiment will be recorded this principle also states that the proper procedure in regards with audio recording, and in regards with consent, right to withdraw. The participant isnt clearly told that opinion is only needed on subject rather than a number of, this section states that withholding information from clients is only exceptional to preserve the integrity of research, and this was the case it was to reduce sociably desirable responses. Question 2 I would rather gather a random group of young teens and inform them that their valuable opinion is required regarding several topics. They would be debriefed with the experiment, asked whether or not they wish to withhold their identity, consent would be needed regarding audio recording and quoting participants. Their rights to withdraw would also be made clear. They would be reassured this is not a test. Question 3 I would fully provide my intentions behind the experiment, that it was a focus topic I was researching on. I would give this additional information because I would have gotten answers from the participant without a cofounding variable, then knowing the intentions behind it, and to avoid any further deception I would make my intentions known, and gives them the right to withdraw if they wish, and if they do so I would then destroy any gathered data including audio recordings.

Stem Cell Research Paper Example | Topics and Well Written Essays - 1250 words - 1
Stem Cell - Research Paper Example The paper tells that cells with the ability to divide constantly as well as distinguish and extend into numerous cells and tissues of various kinds are known as stem cells. They are ââ¬Ëblankââ¬â¢ cells as they do not display any precise physiological predisposition. With the onset of appropriate conditions, in vitro or in vivo, stem cells develop into focused tissues and organs as they are self-sufficient and replicate by the process of cell division, indicating that stem cells are biological entities prevalent in multicellular organisms. As stem cells possess distinctive eminence and research embraces an immense assurance for the management and cure of critical and unbearable ailments like Alzheimer's disease, Parkinson's disease, cancer, diabetes and neurological as well as metabolic disorders, diseases related to hear, stroke, bone condition, osteoarthritis, rheumatoid arthritis, as well as conditions like multiple sclerosis. Stem cells could also be grown to become new tis sue for use in transplant medicine. Research is being carried out across the world to decipher the underlying genetic and biochemical facts triggering stem cell delineation to new cells capable of repairing distorted tissues and organs. Stem cells pave the way towards understanding of various diseases and syndromes. Stem cells are promising resources to test the drugs and agents. Stem cells are pluripotent, i.e. capable of replicating into similar kind of cells or they are capable of specializing into any other specific tissue. There are various categories of stem cells: Embryonic stem cells- They are procured from the interior cells of the blastocyst. Fetal stem cells- They are procured from the germ line tissues of aborted fetus. Umbilical cord stem cells- Blood of the umbilical cord encompasses stem cells similar to the cells present in the bone marrow. Placenta derivative stem cells- Source of enormous stem cells. Adult stem cells- Numerous adult tissues also possess stem cells. These stem cells are harvested to rectify ailments or cloning tissues, organs, animals or humans or they may be harvested for gene-line engineering. The gene-line engineering aims to function towards disease resistance and functional improvement. Induced pluripotent cells- Through nuclear programming scientists have transformed adult cells into stem cells. Nuclear programming alters the genes to behave like embryonic stem cells and thereby avert immune rejection, although adverse effects could not be documented so far. Amniotic fluid stem cells- Researchers have documented the presence of stem cells in amniotic fluid (Where do stem cells come from?; Stem cells: What they are and what they do?). Scientists are using stem cell lines derived from the single stem cell. They are devoid of genetic defects and could be stored as well as used for various research purposes to get regenerative medicines for damaged or degenerated tissues through gene manipulation technique which aids in gene rating

The nyquist theorem is one of the deciding factor in data communication.
The nyquist theorem is one of the deciding factor in data communication. PART A Q1. The Nyquist theorem is one of the deciding factor in data communication. The fibre optics as well as the copper wires are communication mediums. Do you think the theorem is valid for the fiber optics or for the copper wires. Ans. Nyquist theorem is valid for both fibre optics and copper wires this is because the Niquist theorem is purely depend upon the mathematic function and has not any concern with the transmission media for communication. According to Henry Nyquist, a perfect channel has a finite transmission capacity. He derived an equation expressing the maximum data rate for a finite bandwidth noiseless channel. Nyquist said that if an arbitrary signal has been run through a low-pass filter of bandwidth B, the filtered signal can be completely reconstructed by making only 2Bsamples per second. Sampling the line faster than 2B times per second is pointless because the higher frequency components that such sampling could recover have already been filtered out. If the signal consists of L discrete levels, Nyquists theorem states: Maximum bit rate =2* Bandwidth log2 L. For noisy channel: Capacity = bandwidth * log2 (1+SNR), where SNR is signal to noise ratio. Q2. Noise affects all the signals which are there in air. There are some communicating modulation techniques. Noise affects which of the modulation technique the most. Ans. Noise is defined as the disturbance in the signal. When data is send over the network in the form of signal, due the various natural or unnatural circumstances produce disturbance in the signals which is called noise. The noise is various kinds such as thermal noise, crosstalk, and impulse noise. Noise affects all the signals but there are some modulation techniques which are used to reduce the noise. These techniques are: Amplitude modulation Frequency modulation Phase modulation The amplitude modulation is affected most by the noise this is because there is the change in only amplitude and the amplitude is affected easily by the noise. Q3. An analog signal carries 4 bits in each signal element. If 10,000 signal elements are sent per sec, find the Baud Rate and Bit Rate? Ans. Given signal carries r =4 Signal element s=10000 Let N be the bit rate We know that S = N*(1/r) à ° N= S*r à ° N= 10000* 4 à ° N=40000 bps Bit rate is equals to 40000bps Q4. What are the reasons for the imperfection caused in transmission media? How the perfection can be measured? Ans. There are certain reasons for the imperfection caused by the transmission media. These reasons are describe below: Attenuation: All the transmission media has some sort of loss of signal i.e. called attenuation which make then imperfect. During the transmission of the signal from one place to another the loss or energy is occurred which reduce the overall strength of the signals which is called attenuation. For this is reason amplifier is used in various place in the transmission. Noise: Noise is the basically the disturbance which is produced in the signal when the signal send over the transmission media then the natural and un natural climate affect the signal such as pollution etc.à So that some kind of distortion is occur in the signal. Every transmission media is affected with the noise which makes the signal imperfect. Distortion: Distortion means that the change in the signal. Due to some circumstance there must be change in the signal. The signal may deviate from actual one this is called distortion. The perfection can be measure in the form the above three. A transmission media which has less attenuation, less noise and less distortion that transmission media is called perfect. Q5. There are numerous multiplexing techniques available. What in your opinion is the most appropriate multiplexing technique for the fiber optics as well as copper wires? Ans. Multiplexing is the process of converting n signal to the one. There are various technique but two basic technique are FDM(Frequency Division multiplexing) TDM(Time Division multiplexing)à wavelength Division multiplexing In fiber optics multiplexing the best technique used is called WDM Wavelength division multiplexing. The basic principle of WDM on fibers is that n fibers come together at an optical chamber, each with its energy present at a different wavelength. The four beams are combined onto a single shared fiber for transmission to a distant destination. At the far end, the beam is spilt up over as may fibers as there were on the input side. Each output fiber contains a short special- constructed core that filters out all but one wavelength. The resulting signals can be routed to their destination or recombined in different ways for additional multiplexed transport. In the case of the copper wire Frequency division multiplexing technique is used. First the voice channels are raised in frequency, each by a different amount. Then they can be combined because no two channels now occupy the same portion of the spectrum. Notice that even though there are gaps (guard bands) between the channels, there is some overlap between adjacent channels because the filters do not have sharp edges. But nowadays there is use of the Time division multiplexing is used which is particularly deal with the digital signal. In this technique the conversion must be take place from analog to digital signals.à Q6. While transferring the data from the transmission medium there are various aspects of your data getting tempered by other users? Whats your opinion is the most secure and insecure transmission medium. Justify your answer with an example. Ans. Transmission media is the aspect which is caused for tempering of data by the other. All transmission media has this problem. When we use the copper wire it can be taped by another one. One of the improve version is the optical fibre which An improved media is fiber optic cabling, this media does not emanate any signals since it uses light sources to transmit the signals from node to node. It has proved to be the most secure media available for use on LANs today and will continue to be the most secure media until the black hats discover a way to tap it undetected. The last medium reviewed is the wireless media which uses the airways as their path from node to node. The only way to guarantee secure transmissions is to use a layered approach, or combination of techniques to try to encrypt the data. The best way currently to encrypt data over LANs is to use the IPSec protocol with any of the discussed media. IPSec security is compatible with all types of media so it is the one thin g in common with allmedia that will almost guarantee the security of the pathways between nodes. PART B Q1.Assume a stream is made of ten 0s .Encode this stream , using following encoding schemes .How many can you find for each scheme ? Unipolar NRZ-L NRZ-I RZ Manchester Differential Manchester Ans. 0 0 0 0 0 0 0 0 0 0 Unipolar: it can be drawn as: NRZ-L:à It can be drawn as: NRZ-I: it can be drawn as: RZ: it can be drawn as: Manchester: it can be drawn as: Differential Manchester: it can be drawn as: Q2. Two channels ,one with bit rate of 150kbps and another with a bit rate of 140kbps,are to be multiplexed using pulse stuffing TDM with no synchronization bits.Answere the following: What is the size of frame in bits What is the frame rate ? What is the duration of a frame? What is the data rate? Ans. Given bit rate of 1st channel=150 kbps Given bit rate of 2nd channel=140kbps Ans1. We allocate 3 slot for first and 3 slot for 2nd and we each size of frame is six bit. Ans2. Q3. Contrastà compare sampling rate received signal? Ans. In the conversion of the analog to digital, pulse code modulation is used. Sampling is the first stage of the PCM. The analog signal is sampled every Ts second. Where Ts is the sample interval or period. The inverse of sampling interval is called the sample rate or sampling frequency and denote fs where fs = 1/Ts. To produce the anolog signal one necessary condition is that the sampling rate be at least twice the highest frequency in the original signal. This is according to the Nyquist theorem. e.g. Wo well-known examples where sampled sound is used are the telephone and audio compact discs. Pulse code modulation, as used within the telephone system, uses 8-bit samples made 8000 times per second. In North America and Japan, 7 bits are for data and 1 is for control; in Europe all 8 bits are for data. This system gives a data rate of 56,000 bps or 64,000 bps. With only 8000 samples/sec, frequencies above 4 kHz are lost. Received signal strength is a measure of the power present in a received radio signal. RSSI is generic radio receiver technology metric which is usually invisible to the user of device containing the receiver but is directly known to users of wireless networking Q4. Synchronization is the problem in data communication. Explain? Ans. Synchronization technologies are designed to synchronize a single set of data between two or more devices, automatically copying changes back and forth. For example, a users contact list on one mobile device can be synchronized with other mobile devices or computers. Data synchronization can be local synchronization where the device and computer are side-by-side and data is transferred or remote synchronization when a user is mobile and the data is synchronized over a mobile network. In synchronous communications receiver, this specification discloses a decoder for generating a clock signal to synchronize the receiver with the information data rate of the received signal. The implementation of a decoder apparatus as a periodic finite state machine allows a clock signal to be extracted from the energy or transitions of the encoded signal. Such a decoder can define clock information over a large range of data rates. A band pass filter tuned to the characteristic frequency being re ceived can be coupled to the input of the decoder to limit the synchronization range to that desired by the receiver. Q5.Can bit rate be less than the pulse rate? Why or why not? Ans. Yes it is possible. Pulse rate is defined as the number of signals element send per second and the bit rate is defined as the number of data element which may be called bits in one second. Data communication needs to increase the data rate and decrease the pulse rate. So that the speed of transmission may be increased and decrease of bandwidth. But in some of the case it may be possible to the bit rate is less than pulse rate. This is done when the single pulse can carry more bits. When this happen the congestion Q6. A signal is sampled. Each sample represents one of four levels. How many bits are needed to represent each sample? If sampling rate is 8000 samples per second, what is the bit rate Ans. Given Sampling rate = 8000 We know thatà bit rateà =1/Sample rate So bit rate =1/8000 =0.000125 bps

Descriptive Essay Beach
Miranda Poole 2/3/13 English 101 Descriptive Essay The Beach: A Relaxing Wonderland It is spring break, in the middle of March, my junior year. As I cross the state line into Florida, I picture the ocean as being a place of peace and serenity. Itââ¬â¢s my first time visiting the ocean, and all I can think about is hoping it is as beautiful as the pictures I have seen of it. As I arrive to the beach with all my friends, the eagerness of seeing this peaceful place is rising. I canââ¬â¢t wait to smell the fresh salty air, feel the soft sand between my toes, walk along the breezy shoreline.As we approach the beach, the first thing I notice is the sky. As I look into the cloudless, cerulean blue sky and see the flawlessness of life; in the distance, rolling clear-blue waves crash into each other with such force as that of football players. The sky is breathtaking along with the sounds of the waves and the tide washing onto the shore. The water reminds me of crystals shimmering in th e water with the sun reflecting off of it. As the sun sets, the sky turns into a pink hue with a bright orange sun going down into the horizon.We stroll on the beach, and my feet sink into the soft sand. I stroll along, and the grainy, slick, brown sugar sand pulls my bare feet under and leaves a perfect imprint. I pick up a handful and sift it from my palm slowly, feeling the grittiness of sand with each finger. The view down the beach of the white, but slightly brown sand was enough to make my knees go weak. The sand is such a sensational feeling between my toes and a beautiful view against the crystal blue water. The beach is a beautiful scene of peace and tranquility. Every moment is a different scene.As I sit in my chair I can see all the sights of summer; children building sand castles along the ocean's edge, to my right I observe an elderly couple enjoying a good book. The waves crash into one another, the breeze blowing from the tide, the smell of salty ocean, and the sticky air clinging onto my skin. Charging into the ocean with vigorous splendor and utter excitement, I insert my bare feet into the sea and am taken aback by the shocking coolness of the water. Bringing myself to a halt at mid-calf, I then trudge through the soft currents that splash upon my legs. An abundance of symbiotic, vibrantly olored, and variously sized fish swarm around my feet. Their bodies brush my leg with negligence as they strive to get from one place to another. I wish to stay here forever and realize, at this point, this is where I need to come for serenity and harmony, where all things seem perfect and care free. There is nowhere in the world quite like this, so peaceful and calm. The beach is a wonderland for all ages. Whether you want to have fun in the sun, or relax while reading a good book, the beach is the place to go. The beach is an unforgettable experience that one must witness in their lifetime.
