The Types of Parallel Universes

The Types of Parallel Universes Physicists talk about parallel universes, but its not always clear what they mean. Do they mean alternate histories of our own universe, like those often shown in science fiction, or whole other universes with no real connection to ours? Physicists use the phrase parallel universes to discuss diverse concepts, and it can sometimes get a little confusing. For example, some physicists believe strongly in the idea of a multiverse for cosmological purposes, but dont actually believe in the Many Worlds Interpretation (MWI) of quantum physics. It is important to realize that parallel universes are not actually a theory within physics, but rather a conclusion that comes out of various theories within physics. There are a variety of reasons for believing in multiple universes as a physical reality, mostly having to do with the fact that we have absolutely no reason to suppose that our observable universe is all that there is.   There are two basic breakdowns of parallel universes that might be helpful to consider. The first was presented in 2003 by Max Tegmark and the second was presented by Brian Greene in his book The Hidden Reality. Tegmarks Classifications In 2003, MIT physicist Max Tegmark explored the idea of parallel universes in a paper published in a collection titled  Science and Ultimate Reality. In the paper,  Tegmark breaks the different types of parallel universes allowed by physics into four different levels: Level 1: Regions Beyond Cosmic Horizon: The universe is essentially infinitely big and contains matter at roughly the same distribution as we see it throughout the universe. Matter can combine in only so many different configurations. Given an infinite amount of space, it stands to reason there exists another portion of the universe in which an exact duplicate of our world exists.Level 2: Other Post-Inflation Bubbles: Separate universes spring up like bubbles of spacetime undergoing its own form of expansion, under the rules dictated by inflation theory. The laws of physics in these universes could be very different from our own.Level 3: The Many Worlds of Quantum Physics: According to this approach to quantum physics, events unfold in every single possible way, just in different universes. Science fiction alternate history stories utilize this sort of a parallel universe model, so its the most well-known outside of physics.Level 4: Other Mathematical Structures: This type of paralle l universes is sort of a catch-all for other mathematical structures which we can conceive of, but which we dont observe as physical realities in our universe. The Level 4 parallel universes are ones which are governed by different equations from those that govern our universe. Unlike Level 2 universes, its not just different manifestations of the same fundamental rules, but entirely different sets of rules. Greenes Classifications Brian Greenes system of classifications from his 2011 book, The Hidden Reality, is a more granular approach than Tegmarks. Below are Greenes classes of parallel universes, but weve also added the Tegmark Level that they fall under:   Quilted Multiverse (Level 1): Space is infinite, therefore somewhere there are regions of space that will exactly mimic our own region of space. There is another world out there somewhere in which everything is unfolding exactly as it unfolds on Earth.Inflationary Multiverse (Level 1 2): Inflationary theory in cosmology predicts an expansive universe filled with bubble universes, of which our universe is just one.Brane Multiverse (Level 2): String theory leaves open the possibility that our universe is on just one 3-dimensional brane, while other branes ​of any number of dimensions could have whole other universes on them.Cyclic Multiverse (Level 1): One possible result from string theory is that branes could collide with each other, resulting in universe-spawning big bangs that not only created our universe but possibly other ones.Landscape Multiverse (Level 1 4): String theory leaves open a lot of different fundamental properties of the universe which, combined with the in flationary multiverse, means there could be many bubble universes out there which have fundamentally different physical laws than the universe we inhabit. Quantum Multiverse (Level 3): This is essentially the Many Worlds Interpretation (MWI) of quantum mechanics; anything that can happen does... in some universe.Holographic Multiverse (Level 4): According to the holographic principle, there is a physically-equivalent parallel universe that would exist on a distant bounding surface (the edge of the universe), in which everything about our universe is precisely mirrored.Simulated Multiverse (Level 4): Technology will possibly advance to the point where computers could simulate each and every detail of the universe, thus creating a simulated multiverse whose reality is nearly as complex as our own.Ultimate Multiverse (Level 4): In the most extreme version of looking at parallel universes, every single theory which could possibly exist would have to exist in some form somewhere.

Tongan cultural Diversity - Essay Example Majority of the people are farmers or fishermen. There are no major metropolitan areas in Tonga and the numerous islands are dotted by closely located villages. The Tongans or the Polynesians are a group that inhabit about hundred and fifty islands lying to the east of Fiji. The human population is neatly confined on islands that are separated by vast expanses of oceans. These islands vary in size, resources and degree of isolation. Each of these settlements developed their distinctive features in isolation. The wide variety of cultural differences found within the same group has been a cause of study by various ethnologists and archaeologists. Polynesia has been called a cultural laboratory because of the adaptive variation of a single culture on its far-flung islands and island groups (Davidson, 1977). Polynesia was isolated from other cultures but did have interactions with other cultural traditions. It developed some of its distinctive features through interaction with West Polynesia and Fiji. Similarities between the various West Polynesian cultures have been found due to the same origin. According to D’Arcy (2003), the Pacific Islanders were highly localized in their affinities and expansive in their interactions. As a result they embraced multiple cultural affinities, both local and regional. Western Polynesia consisted of two archipelagos – Tonga and Samoa and a few other smaller more isolated islands. All of these islands shared many common features with Fiji. Interaction with other communities meant that change could be very rapid and changes to one community’s circumstances could have regional implications. Distinct variants of the Polynesian language and culture can be noticed in each of the islands and even though the dialects differ, they can be recognized as dialects of a single language. in The Tongan island consists of smaller islands with a total

Human Resource Management, Questions Essay Example | Topics and Well Written Essays - 750 words

Human Resource Management, Questions - Essay Example It is important to ensure that all employees remain customer oriented and demonstrate high level of service. Therefore, as a manager, I would propose to include the following strategies to help employees cope with stress. Firstly, employees will be recommended to attend communication skills courses to ease and improve their relationship with customers and even co-workers. Such courses will also teach the employees useful tactics in handling difficult clients. Secondly, the organization will introduce a 'buddy system', where an employee is attached to another individual to act as support for one another. The system will encourage individuals to openly discuss difficulties that they face at work and share tips for improving the situation. In addition, the system will also encourage employees to keep a lookout for alarming stress symptoms that their colleagues may be having so that these can be addressed immediately. Stress, if applied continuously and excessively, is a negative physical reaction to situations that upsets an individual's balance. On the contrary, small doses of it can actually have a positive effect on an individual by spurring him or her to perform better at something. In this case, the manager's statement is directed at Janine, who constantly experiences the symptoms of stress. Indeed, symptoms of stress can be seen in a person's behaviour, emotion, and physical conditions. Chronic stress is harmful to one's health because it disrupts the body's system, causing high blood pressure and poor immune system, increasing the risk of heart attack and speeding up the aging process. Therefore, the manager's statement about the unfavourable effect of stress on one's performance rings true. Answer to Question 4 Sammie is de-motivated because he is unsure of his skills in dealing with different kinds of people that he meets at work. As such, he feels he is incompetent to perform well at work. Using Social Cognitive Theory, Sammie's manager can motivate him by planning, anticipating likely outcomes and setting goals. Planning a course of action will help to anticipate the likely outcomes of these actions, while setting clear and attainable goals will ensure that Sammie remains challenged and motivated. For instance, the manager can discuss with Sammie the difficulties that he is facing with his job; draw up a plan to help Sammie overcome his fears, and keep a log book with daily targets, that Sammie can use to keep track of his daily experiences with the customers he has dealt with. Next, Sammie's manager can put him on a training session for a period where he will observe his co-workers on the job. This is known as vicarious learning and by such observations, Sammie will be able to retain positive points and use them in actual situations. This will also better prepare Sammie in the future. This is ideal instead of immediately putting Sammie to deal with customers because the observations will prepare him for what to expect. Self-regulating mechanisms increase self-worth and personal satisfaction by regular monitoring of one's actions. Sammie's manager
