Attitudes Towards Implementation of Evidence Based Practice

Attitudes Towards Implementation of Evidence Based Practice Introduction The term of evidence based practice (EBP) was firstly used in medicine as evidence based medicine, after that the term developed and being used in nursing with purpose of build up scientific database to improve nursing as science (Colyer and Kamath, 1999). Evidence based practice was passed through three stages; in which the EBP was appeared in Old Testament which was the first form and appearance of EBP; after that the EBP was developed in different form in middle ages, in which the period of middle ages was considered a stage of renaissance of the EBP which characterized by beliefs-related methods of treatment; the third stage of EBP was the modern stage, in which the modern stage considered the last version of EBP that began at 1972; in which the modern version of EBP was the EBP that widely known form among highly educated and professional nurses (Claridge and Fabian, 2005). The Bible was the oldest known source in EBP documentation, in which the Bible contains a story that was represented as an interventional research that progress for ten days (Weingarten, 2003); the story in the Bible said Then Daniel said to the guard whom the master of the eunuchs had put in charge of Hananiah, Miscael and Azariah and himself .Submet us lo this rest for ten days. Give us only vegetables to eat and water to drink: then compare our looks with those of the young men who have lived on the food assigned by the king and be guided in your treatment of us by what you see. The guard listened to what they said and tested them for ten days. At the end of ten days they looked healthier and were better nourished than all the young men (Claridge and Fabian, 2005, P. 548). During the second stage of EBP (1700s-1900s), the EBP was restricted to believes-related methods of treatment; in which Blood-letting was the main treatment for many diseases in middle age period (Klar and Donner, 2002). Physicians and priests were used Blood-letting; in which Physicians and priests were believed that diseases caused by wicked souls; in which the diseased patients should be injured to expel the wicked souls with blood outside of patients bodies (Klar and Donner, 2002). During the last four decades, the EBP was featured in a modern form; in which the borderline for modern period of EBP was began in 1972 by Archie Cochrane (Klar and Donner, 2002). Cochrane (1972) published a paper with title of Effectiveness and efficiency: random reflections on health services; in which the paper was discuss and evaluate the effect of randomization (the randomization was regard to patients and regard to intervention) on the outcomes of the patients health. The Cochranes paper was the first paper reflects the importance of randomized clinical trials; in which Cochrane was found that the randomization of the sample and intervention will exhibit evidence with high quality which improve the quality of health care provided and improve health outcomes of the patients (Cochrane, 1972). Melnyk and Fineout-Overholt (2005) defined EBP as a knowledge-based conflict-resolving strategy that performed by adapting best available evidence to provide best possible care for patients and their families. Furthermore, Evidence Based Practice is a process of integration of research-based results which contribute to achieve best practice (Institute of Medicine, 2001). In addition, Sackett, Rosenberg, Gray (1996) estimated that evidence based practice is synchronous combination of professional nursing experience and research with high level of evidence under patients believes and values consideration. Besides that, Ingersoll (2000) documented that evidence based practice is meticulous, unambiguous, and well-judged theoretical information and reliable research-findings to provide effective decisions about patients care regard to patients and organizational needs (P. 152). Furthermore, evidence based practice defined as Explicit and judicious decision making about health care deliver y for individuals or groups of patients based on the consensus of the most relevant and supported evidence derived from theory-derived research and data-based information to respond to consumers preferences and societal expectations (Driever, 2002, p. 593). Evidence based practice is considered as a magical solution for complicated health problems (Institute of Medicine, 2001). Furthermore, evidence based practice considered wide discipline term used as a solution to clinical-related problems which began to provide findings and basics of clinical decision on best reliable and evident researches with purpose of improving health care provided (Sackett, Strauss, Richardson, Rosenberg, and Haynes, 2000). The Institute of Medicine (2001) was illustrated that EBP process provide intensive care to patients, using effective recent researches to achieve desired outcomes, and provide cost effective standard care. In addition, another study found that EBP enhance nurses professions by improving nurses knowledge and skills to analyze, understand and develop research (Melnyk and Fineout-Overholt, 2005). Evidence Based Practice improves nurses ability to be excellence profession in areas of practice, and improves patients health outcomes by providing high qualified nurses (Institute of Medicine, 2001). Evidence based practice improve patients outcomes within four dimensions; clinical dimension (improve signs and symptoms of patients diseases), life quality dimension (improve patient satisfaction upon to life), functional dimension (improve patients ability to achieve daily living activity), and economic dimension (using EBP was prove ensure of cost effectiveness for patient and hospital) (Weaver, Warren, and Delaney, 2005). In addition, Newhouse, Dearholt, Poe, Pugh, and White (2005) demonstrated that the evidence based practice improve efficacy of health care provided to achieve pleasurable patients outcomes, save patients/nurse time, and use of EBP considered cost effective for patients, families, and hospitals. Melnyk, Fineout-Overholt, Sadler, and Green-Hernandez (2008) documented that implementation of evidence based practice can be achieved by improving nurses knowledge and skills about research and evidence based practice, improve and strengthening nurses beliefs to reinforce nurses to be integrated within evidence based practice environment. Evidence based practice education allow nurses to formulate and answer any research question raised from clinical area by recent and reliable researches, allow nurses to critique and evaluate any research according to level of evidence, allow nurses to conduct researches according to patients needs; family; nurse; and hospital needs, and allow nurses to share research findings as journal club activity (Melnyk, Fineout-Overholt, Sadler, and Green-Hernandez, 2008). Another study conducted by Wolf and Greenhouse (2007) documented that using of EBP is significantly needed in clinical practice, in which EBP pleasured to achieve improvement in patientfamilynurse education regard to condition and treatment, improve quality of health care provided by nurse and hospital, improve using new technology in clinical setting as computers, and build nurses community prepared with recent scientific information. Most of health care provided by nurses nowadays is based on traditional practice with observable lacking in evidence-based practice (Mariano, Caley, Eschberger, Woloszyn, Volker, Leonard, et, al. 2009). Furthermore, an Iranian study was conducted to identify the Iranian nurses perception toward EBP, the Iranian study was conducted by using convenience sample of 21 nurses who undergone within qualitative research design; in which the Iranian study was documented that 21 participants from nurses did not listen about the concept of evidence based practice before and they did not implement EBP in clinical area (Adib-Hajbaghery, 2009). American and Netherlandic studies conducted at 1998 and 2001 respectively; was estimated that about 35% of hospitalized patients do not receive evidence based care (the nurses treat patients according to traditional care that was not based on researches) (Schuster, McGlynn and Brook, 1998; Grol, 2001); in which Estrada (2009) conducted a descriptive study to assess nurses knowledge and attitudes toward EBP, in which the Estradas study was founded that 25% of sample did not hear about EBP previously. Moreover, Melnyk and Fineout-Overholt (2007) was conducted a study to develop two scales; attitude toward EBP scale and implementation of EBP scale, in which Melnyks and Fineout-Overholts study was estimated that 40% of collected sample did not listen and dealt with the concept of EBP previously. Evidence based practice improve patients outcome; in contrast, lack of nurses prepared evidence based practice will affect patients outcomes negatively (Institution of Medicine, 2001); in which, about 25% of health care provided was not sufficient to meet patients needs and the health care provided was not safe for hospitalized patients (Schuster, McGlynn and Brook, 1998; Grol, 2001). Furthermore, Pravikoff, Pierce, and Tanner (2005) conducted a study to evaluate nurses perception to integrate within EBP which conducted by random sample of 1,097 nurses, the researchers were found that more than half of the sample did not listened about EBP previously, more than half of the sample had a negative attitudes toward EBP and those nurses was not integrated within EBP activities, 73% of the nurses had not ability to use electronic database, and all 1,097 nurses had not sufficient information about choosing best researches. The problems that impede of EBP for nursing and medical societies has been reported by Institution of Medicine (2001) in which around 45% of patient did not received professional health care; the implementation of new discovered evidence needs about two decades at least to let the recent of evident researches to be handled and public with nurses and medical stuff worldwide, and health care providers were not adequately prepared to translate recent researches in clinical practice. Hunt (1996) concluded that there is a wide whole between using the findings of researches and clinical practice; in which an interventional study was conducted to evaluate the effect of educational intervention on nurses knowledge and attitudes toward EBP, the pre- test of these educational study was showed that 50% of 49 convenience sample of nurses did not listen about EBP and professional health care provided previously (Varnell, Haas, Duke, and Hudson, 2007). In addition, Melnyk (2006) concluded that the implementation of evidence based practice was little in nursing that explained by Hunt (1996) who documented that there are several factors prevent evidence based practice implementation as: disorientation toward research, lack of beliefs (attitudes) exhibited toward using research, and lack of understanding of research elements. There are some barriers to EBP were appeared; these barriers limit nurses engagement within evidence based practice (Weaver and Sorrells-Jones, 1999). Funk, Champagne, Wiese, and Tornquist (1991) estimated that these barriers had been originated from different sources and organized within four categorical origins; characteristic of the nurse, characteristic of setting, characteristic of research and characteristic of presentation of research. Furthermore, Funk, Champagne, Wiese, and Tornquist (1991) documented that nurse can be considered as a barrier to implement EBP; in which nurses were unaware about principles of research and research process, and nurses had not sufficient time to implement EBP . Moreover, Funk, Champagne, Wiese, and Tornquist (1991) concluded that practice setting can be considered as a barrier to implement EBP; in which hospitals were not provided sufficient facilitation to implement EBP activity within clinical setting, and nurses had not ability to change pat ient-care procedure without getting permission from hospitals authority to change guidelines. Indeed, Funk, Champagne, Wiese, and Tornquist (1991) documented that research and research presentation can be considered as barrier to implement EBP; in which nurses were believed that research elements as introduction, literature review, methodology, statistical analysis, and conclusion were not understandable clearly within articles. Melnyk (2006) concluded that nurses need applicable teaching strategies to provide nurses with adequate evidence based practice knowledge and skills and provide nurses with positive beliefs (attitudes) toward integration within evidence based practice activity. Di Leonardi (2007) documented that lecture presentation for educational intervention was considered most effective and appropriate teaching strategy; lectures were widely-spread and known perfectly to all universitiescolleges-certificated persons. In addition, Hart, Eaton, Buckner, Morrow, Barrett, Fraser, et, al. (2008) were conducted an educational intervention to teach nurses about nursing research and evidence based practice by using computer-based modules strategy; in which the result was exhibit that the educational intervention improve nurses knowledge and skills about using research and evidence based practice, and improve nurses attitude toward evidence based practice. Lacey (1996) was evaluated 870 courses of the English National Board which contain materials enable student nurses to understand research and evidence based practice, with convenience sample of 30 nurses student; 65% of the students were demonstrated that knowledge, skills about research and evidence based practice were significantly improved after the educational intervention. Furthermore, Hundley, Milne, Leighton-Beck, Graham, Fitzmaurice (2000) compared between long term research course (six months) and short term research course (one month); the study conducted by convenience sample of 481 nurses and midwives; the result showed that nurses who integrated within long term research course were exhibited more knowledge, skills, and attitudes toward evidence based practice than respondent received short term research course. The purposes of this study were to evaluate the effect of educational intervention about evidence based practice and nursing research lectures on the beliefs toward using evidence based practice, to evaluate the effect of educational intervention about evidence based practice and nursing research lectures on the frequency of the implementation of evidence based practice, to determine any differences between two groups (experimental and control group) regard to variables (age, gender, level of education, the experience in clinical area, and the effect of educational intervention that will be implemented), to investigate the variation among socio-demographic variables in response to evidence based practice beliefs and frequency of evidence based practice implementation, and to fixing first block in building EBP team in King Abdulla University Hospital.

Prevention of Stress

To help reduce stress and improve the quality of life, many organizations are becoming more involved in wellness programs. With increasing health care costs, many employers are concentrating on disease prevention and health promotion. By putting a wellness program in place, it leads to a healthier workforce which increases its productivity level, reduces employee absenteeism, creates less overtime, and it also cuts the cost of health benefits (Kizer, 1987). Another reason that many companies are developing a wellness program within the organization is the effect it has on the bottom line. By preventing stress, an organization has happy healthy employees which means t quality and quantity of work will be improved. For example † A middle manager may be a company's shining star, but if he is living in constant disharmony at home, or if his teenage daughter, whom he suspects is using street drugs, did not come home until 3 a. m. last Saturday night this promising manager is not going to be particularly efficient at even routine daily tasks. A worksite wellness program could help† (Kizer, 1987, p. 36). Another contributing factor to higher job related stress is less leisure and vacation time. Throughout the 1980s, the amount of paid time off for employees is act† shrinking. Many European workers are gaining vacation time, while Americans are losing it. † In the last decade, U. S. workers have gotten less paid time off – on the order of three and a half fewer days each year of vacation time, holidays, sick pay, and other paid absences. † (Schor, 1991 p. 32). Many companies faced an economic squeeze in the 1980†³s. Vacations and holidays were among the cost-cutting efforts. DuPont reduced its top vacation allotment time from seven four weeks. They also eliminated three of their paid holidays a year. With the new trend of downsizing, many employees are fearful of job loss and therefore, spend less time away from the workplace (Schor, 1991, p. 32). Individuals who experience high or frequent levels of stress need to learn to cope. High levels of stress can effect job performance and it can also be unhealthy. To maintain a healthy lifestyle, people need to attempt to take responsibility for stress. Those individuals need to learn more about stress in general and how it effects them. They also need to develop technique. for monitoring personal levels of stress and develop techniques to deal with job related stress. Employees should look within the organization on ways to alleviate stress and how to cope more effectively. Organizations an often unnecessarily stressful and should be changed to reduce the negative impact on individuals' physical and mental health (Paine, 1982, p. 21). Three major strategies for strengthening individuals are workshops, stress management skills, and focused short term counseling. Introductory workshops are essential to communicate and educate to be more mentally and physically healthy. Such workshops which specialize in topics as time management or relaxation techniques help to alleviate the stress in one's life (Paine, 1982, p. 22). Finding techniques that deal with personal stress can also be useful in dealing with job stress. Regular aerobic exercise to deep breathing techniques are potentially useful in stress management. Many specialist agree that there is not any one method to overcome the problem. One needs to realize their own self needs and strengths in dealing with stress management (Paine, 1982, p. 23). There are many different ways in which you can deal with job stress. Individuals can take on simple self-help countermeasures. There is also help from friends, colleagues, spouse, or other relatives. Professional help is available from clergymen, physicians, or counselors. The worksite offers several advantages for employees interested in making healthy lifestyle changes. The advantages include: Most employees go to a worksite on a regular schedule, thus providing opportunities for regular participation in wellness programs. Contact with co-workers can provide strong social support which is believed to be a primary force in sustaining lifestyle changes. Opportunities for strong, steady support of the program, as well as for promoting the concept that good health is good for everyone. Programs at the worksite may be less expensive to the employee than comparable programs in the community or may even be offered free as an employee benefit. Because of the varity of data systems available, it is possible to evaluate changes in an employee's health status or other measures resulting from the program. The most attractive feature from an employee†s viewpoint is the fact that the program is convenient. From the employers viewpoint the benefits of worksite health promotion for stress include: Improved employee relations Improved retention Improved community relations. Reduced absenteeism Reduced number of hours lost to late arrivals and sick davs. Since there's no getting around life†s problems, the best way to manage stress is to learn better coping skills. First pinpoint the reasons for stress in your life. Then try changing your attitude about them. Learn what you can control and accept the things you cannot. Practice self talk (this to shall pass, Some day we will laugh about this, or Its a learning experience). Keep your perspective. Ask yourself, â€Å"Will I remember this in five years? † Try to find the positive side to a stressful situation. Do not worry about things that may never happen. Practice positive self-talk, for example,†I can do this,†or â€Å"I'm in control. â€Å"Negative self-talk such as, â€Å"I have to be perfect,† or â€Å"I can't do this,† produces more stress. Take action to manage stress. Changes and stress create energy. Are you using that energy to continue toward your goals? Or are you letting stress make you unhappy and unproductive? Take action to control your stress, both at work and at home. Manage your time better- make a â€Å"to do† list. Make it realistic so you can do the things listed and set priorities. Break task into bite size chunks. Delegate as much as possible. Keep in mind that tomorrow is another day and accept the fact that you may not get everything done today. Make sure you are communicating effectively- Go into stressful meetings as fully prepared as possible. Organize your thoughts, establish eye contact and listen for the whole message, including content feelings, and meanings. Remember that solving problems depends on give and take. Be prepared to negotiate and compromise. Break the tension cycle-At your desk, close your eyes, breathe deeply and relax. Laugh with co-workers, go out for lunch. At home, read a book, take a walk, chat with next door neighbors. Gets plenty of regular exercise and sleep-they will help you cope better. Get organized at home-Set daily and weekly routines for household chores. Delegate some chores to other family members. Cook meals in large quantities and freeze some for later. Plan for emergencies, keep first aid supplies and an extra set of car keys around. Stress can affect your self-esteem and your health, if you let it. Be kind to yourself. Relax, keep a positive attitude and get involved in activities you enjoy. Build on your strengths, take care of yourself Also team to reach out to others. Everyone needs a support system, a network of trustworthy people you care about and who care about you. Share your feelings so that they don't build up. Then focus on building positive energy. Stress is a normal, involuntary response to any demand made upon the body. Stress is very complex. Sources of stress may be made either more positive or more negative by a range of factors related to a given situation. Stress has become a widely used yet poorly understood term. As a result, a number of misconceptions about stress exist. Three of the most identified misconceptions are that: all stress is dab, stress is a part of life and there is nothing you can do about it, and stress is caused solely and completely by environmental factors. Stress is very much a personal condition, and individuals vary in their ability to cope with different forms and levels of stress. An example of this stress on a personal note would be co-worker conflict. When this stress occurs co-workers should discuss this matter privately. If possible, arrange your meeting on neutral grounds. Approach the person in a non-threatening manner. Respond to them with: â€Å"I would like to talk something over with you. † Try to make the other person feel less defensive or angry. Do not blame the other person. Listen closely to the other person. Understanding the other point of view may help you feet less stressful. Focus on ways to solve the problem. In this I mean do not revisit every past negative incident, this may distract from the resolution. Finally if none of the above work, seek help. If necessary talk with an employee assistance counselor who can help develop ground rules for such discussions and promote respectful communications. Stress is a complex process. It can arise in white collar as well as in blue-collar workers. Surveys have found little difference between white and blue-collar workers in terms of complaints, health, life satisfaction, depression, or other indicators of stress. Shift workers are thought to be more susceptible to stress-related illnesses. Because of personal involvement with the disruption in basic steep patterns and disruption in social life. Since every situation is unique, there are probably as many separate sources of stress as there are work situation. This may is important to recognize when seeking to evaluate working environments for sources of stress. Never the less sources of work related stress can be grouped into four general categories. Work load-which means stress resulting from to much work, to little work, work that is to hard or to easy. Work conditions-refers to a wide variety of factors including organization structure, such as job loss, change in work, and similar factors. Work patterns- pertains to shift work, repetitive work, and paced work Work roles-, which can be stressful because of role expectations with efficient use of resources and staff. Employers may also wish to introduce an EAP, which provides an effective strategy for assisting employees with personal and work related problems. Where organizations believe it would be necessary to make decisions about the quality of the proposed program. Such decisions should be made on the basis of a well-defined set of criteria. The following set of eight criteria for evaluating and selecting a stress intervention program is suggested.

Different Dimensions Used in Sir Gawain and the Green...

Different Dimensions Used in Sir Gawain and the Green Knight by J.R.R. Tolkien In Sir Gawain and the Green Knight, J.R.R Tolkien uses many different dimensions to keep the poem interesting. Each dimension that is presented has a contradiction, making the poem somewhat of a fantasy. By using these techniques Tolkien makes the poem more humorous and psychological. As a Christian knight Sir Gawain comes across many obstacles that attempt to lead him astray. He tries to make all the correct actions in his conquest, however sin and temptation force him to decide between good and evil. Although Tolkien presents a tale of a knights chivalry and honor as well as the aspect of death, some of the situations are presented as comedic. I†¦show more content†¦By taking Lady Bertilaks girdle, he puts his faith into something material and also jeopardizes his relationship with Bertilak. When Gawain takes this girdle he is not only acting for himself but his whole assembly of knights. When he goes back and tells his adventure, they all seem to be humbled by Gawa in taking the girdle, when in fact they are actually just laughing at themselves, because they also have to wear the girdle. Although humor plays an important role in the poem of the Green Knight, Tolkien also adds psychological effects in the poem as well. The element of Sir Gawain and the Green Knight that involves the most psychological devices is when Lady Bertilak tries to seduce Gawain. While this is happening, Bertilak is out hunting game to give to Gawain as a gift. In return for Bertilaks gift, Gawain would also give a gift to Bertilak. Each day Bertilak presents a different animal to Gawain, and Gawain gives Bertilak a kiss. Gawain is not aware that with every different animal Bertilak hunts, Gawain embodies the characteristics of that animal when the Lady attempts to seduce him. As the days go on, Gawains characteristics become complex and more involved. Finally on the third day he embodies the fox, which is cunning and sly and will do anything to get out of a peculiar situation. So Gawain does exactly this; he takes the girdle so he can escape from the evil temptations of Lady Bertilak. Along with every other dimension, this too has

The Science of Star Trek

Star Trek is one of the most popular science fiction series of all time and loved by people around the world. In its TV shows, movies, novels, comics, and podcasts,  future inhabitants of Earth go on quests to the far reaches of the Milky Way Galaxy. They travel across space using advanced technologies like warp drive propulsion systems and artificial gravity. Along the way, the Star Trek denizens explore strange new worlds. The science and technology in Star Trek are dazzling and lead many fans  to ask: could such propulsion systems and other technological advances exist now or in the future?   The starship Enterprise came into public view with the first Star Trek show in the 1960s. Getty Images/ In a few cases, the science is actually quite sound and we either have the technology now (such as the first rudimentary medical tricorders and communications devices) or someone will be developing it sometime in the near future. Other technologies in the Star Trek universe are sometimes  in agreement with our understanding of physics—such as the warp drive—but are highly improbable to ever exist. For those, we might have to wait until our technology abilities catch up to theory. Still Trek ideas are more in the realm of imagination and dont stand a chance of ever becoming a reality. What Exists Today or Will Sometime in the Near Future Impulse Drive: The impulse drive is not unlike our chemical rockets of today, only more advanced. With advances taking place today, it is not unreasonable to think that we will one day have propulsion systems similar to the impulse drive on the starship Enterprise. Cloaking Devices: The irony here, of course, is that this is a technology that humans have yet to grasp in the early  Star Trek series (although the Klingon Empire has it). Yet this is one of the technologies that is closest to becoming a reality today. There are devices that cloak small objects up to the size of people, but making an entire spaceship disappear is still quite a ways away. Communication Devices: In Star Trek, no one goes anywhere without one. All members of Starfleet carried with them a device that allowed them to communicate with other members of the crew. In reality, many people dont go anywhere without their smartphones, and there are even working comm badges. Tricorder-like Devices: In Star Trek, portable sensors are used in the field for everything from medical diagnoses to rock and atmospheric sampling. Todays spacecraft on Mars and beyond use such sensors, although not quite yet portable. In recent years, teams of inventors have created working medical tricorder-like machines that are already making their way into the market.   The Star Trek-style tricorder medical devised may come to us as part of apps for smartphones, as shown in this cell phone-like device that records health data. Getty Images Possible, but Highly Improbable Time Travel: Time travel into the past or the future is not in strict violation of the laws of physics. However, the amount of energy needed to accomplish such a feat takes the practicality of it out of reach. Wormholes: A wormhole is a theoretical construct of general relativity that, under certain circumstances can be created in places like black holes. The main problem is that passing through (or even approaching) a wormhole created by such objects would be potentially deadly. The alternative is to create a wormhole in a location of your choosing, but this would require the presence of exotic matter that isnt known to exist in large quantities and would require so much energy that it is not likely we could ever achieve it. So while wormholes may very well exist, it seems highly improbable that we would ever be able to travel through one. A science-fiction look at a spacecraft traveling through a wormhole to another galaxy. So far, scientists have not found a way to make such technology possible. NASA Warp Drive: Like wormholes, warp drive does not violate any laws of physics. However, it too would require such immense amounts of energy and exotic matter that it seems improbable that developing such technology will ever be possible. Energy Shields and Tractor Beams: These technologies are linchpins to the Star Trek series. We could someday have technologies that have a similar effect as those used in the films. However, they will likely work in a much different manner. Matter-antimatter Power: The starship Enterprise famously uses a matter-antimatter reaction chamber to create the energy used to power the ship. While the principle behind this power plant is sound, the problem is creating enough antimatter to make it practical. As of today, it is extremely unlikely that we will ever obtain enough antimatter to justify making such a device. Most Likely Impossible Artificial Gravity: Of course, we actually have artificial gravity technology in use today. For these applications, we use rotating centrifuges to produce a similar effect to gravity, and such devices may make their way onto spacecraft of the future. However, this is quite different from what is used in Star Trek. There, an anti-gravitational field is somehow created on board the starship. While this may be possible someday, our current understanding of physics is at a loss as to how this might actually work. This is mostly because we dont actually understand gravity that well. So it is possible that this technology might move up the list as our scientific understanding grows.Instantaneous Matter Transport: Beam me up, Scotty! Its one of the most famous lines in all of science fiction. And while it allows the plot of the Star Trek films to move along at a more rapid pace, the science behind the technology is sketchy at best. It seems highly unlikely that such technology will ever exi st. Edited and updated by Carolyn Collins Petersen.
