Quantum Zeno Effect

The quantum Zeno effect is a phenomenon in quantum physics where observing a particle prevents it from decaying as it would in the absence of the observation. Classical Zeno Paradox The name comes from the classic logical (and scientific) paradox presented by ancient philosopher Zeno of Elea. In one of the more straightforward formulations of this paradox, in order to reach any distant point, you have to cross half of the distance to that point. But to reach that, you have to cross half that distance. But first, half of that distance. And so forth... so that it turns out you actually have an infinite number of half-distances to cross and, therefore, you cant actually ever make it! Origins of the Quantum Zeno Effect The quantum Zeno effect was originally presented in the 1977 paper The Zenos Paradox in Quantum Theory (Journal of Mathematical Physics, PDF), written by Baidyanaith Misra and George Sudarshan. In the article, the situation described is a radioactive particle (or, as described in the original article, an unstable quantum system). According to quantum theory, there is a given probability that this particle (or system) will go through a decay in a certain period of time into a different state than the one in which it began. However, Misra and Sudarshan proposed a scenario in which repeated observation of the particle actually prevents the transition into the decay state. This may certainly be reminiscent of the common idiom a watched pot never boils, except instead of a mere observation about the difficulty of patience, this is an actual physical result that can be (and has been)  experimentally confirmed. How the Quantum Zeno Effect Works The physical explanation in quantum physics is complex, but fairly well understood. Lets begin by thinking of the situation as it just happens normally, without the quantum Zeno effect at work. The unstable quantum system described has two states, lets call them state A (the undecayed state) and state B (the decayed state). If the system is not being observed, then over time it will evolve from the undecayed state into a superposition of state A and state B, with the probability of being in either state being based on time. When a new observation is made, the wavefunction that describes this superposition of states will collapse into either state A or B. The probability of which state it collapses into is based on the amount of time that has passed. Its the last part which is key to the quantum Zeno effect. If you make a series of observations after short periods of time, the probability that the system will be in state A during each measurement is dramatically higher than the probability that the system will be in state B. In other words, the system keeps collapsing back into the undecayed state and never has time to evolve into the decayed state. As counter-intuitive as this sounds, this has been experimentally confirmed (as has the following effect). Anti-Zeno Effect There is evidence for an opposite effect, which is described in Jim Al-Khalilis Paradox as the quantum equivalent of staring at a kettle and making it come to the boil more quickly. While still somewhat speculative, such research goes to the heart of some of the most profound and possibly important areas of science in the twenty-first century, such as working toward building what is called a quantum computer. This effect has been  experimentally confirmed.

Buddhism The Four Noble Truths And The Eight Fold Path

INTRODUCTION In Buddhism, the religion evolves around the two basic concepts of Buddhist teachings – the Four Noble Truths and the Eight Fold Path. According to the oxford dictionary, a ritual is defined as, â€Å"a religious or solemn ceremony consisting of a series of actions performed according to a prescribed order.† In this religious faith, Buddhists value a plethora of teachings which, not only ties with the Noble teachings and the Eight Fold Path, but value key concepts of what should be evident – and to an extent, required – within a Buddhist ritual such as marriage. These are as such: Respect, wisdom, and love – all of which substantially correspond with marriage. Such concepts of the iconic ritual – on multiple levels – offer a thorough spiritual connection and bond that can be interpreted into an everyday Australian context. †¢ Oxford University Press.

That is what the two families fighting causethe city. Fear. Fear that the city has against what the two families coulddo to each other could cause a civil war between the city, the Montagues,and the Capulets. #5The two men are different because Paris is more intent and lean towardsgetting married while Romeo is interested in the IDEA of love, romance,marrage, and seem to love the idea of doing dirty bad things with Julietand paste them off by calling them things lovers do.

Three Programs To Listen And Analysis Essays -

Three Programs To Listen And Analysis For this project, I chose to pick three programs to listen to on PeachState Radio, station 88.1 on the FM dial. The program's were Classical24, which aired Monday through Thursday from 12am-5am; Jazz AfterHours which aired from 12am-5am on Fridays and Saturdays; and CarTalk which aired Saturdays from 10am-11am. I chose these programsbecause I thought it would give me an insight on a good variety of theprograms played on national public radio. Classic 24 played an arrayof selections ranging from Mozart and Beethoven to Haydn and Chopin. Jazz After Hours featured names common to me like John Coltrane andRosemary Clooney, but also many others whose music that I foundquite enjoyable. Still, the program I liked the most and chose to writeabout was Car Talk. Car Talk airs weekly on the National Public Radio. It's a call-inradio show that allows listeners to ask questions about problems withtheir car. Brothers Click and Clack Tappet help the people solve theirtroubles in a comical, yet help ful way. The brothers always seem topoke fun at their callers, making them feel somewhat stupid, yetalways bounce back with an answer to the problem. The episode Ipicked to discuss aired February 20, 1999. The first caller to the program was Doris, who had a 1988 PontiacSunbird that was running hot. She complained that at a time whiledriving, the temperature went way up. She said that she went to hermechanic and he said he was too busy and would help her tomorrow. Click and Clack commented that if she was having a heart attack,would the doctor ask her to come back the next day? They told hernot to go back to a mechanic that puts you off. The most probablesolution, they said, was simply to change the thermostat and to makesure that the electric cooling fan was working. Another caller, Ann, who owned a 1994 Mercury Villager wasconcerned with whether or not her van was able to make across-country trip while pulling a pop-up trailer. Click and Clack saidthat it probably would not. They said she should drive it out to PikesPeak, let the kids push it off, and go buy a Yukon to pull the camper. Of course they were only kidding and told the caller that she shouldhave the engine and transmission properly serviced and that it wouldbe fine. The last one I want to talk about was the funniest to me. A womancalled in about clutch problems on a 1989 Volkswagon. She said thatshe had been through five clutches and the car only had 85,000 mileson it. She said that she had taken the car back to the dealership forrepairs, and each time they could not figure out the problem. Themechanics said that the teeth on the flywheels kept breaking and thepressure plate was splitting in half. Click and Clack asked questions totry to find a solution but the results were negative. They called her a?wacko woman driver? and said the only thing wrong with her car wasthat she needed to learn to drive properly. Car Talk was a very informative and humorous program. I did notexpect to get a laugh out of it, but to my surprise I did. It can reallyhelp solve those troublesome car problems. Car Talk was a really coolshow and if I ever am riding along at ten in the morning on aSaturday, I would definitely listen to it again.

How to Turn a Worksheet into an Engaging Activity

How to Turn a Worksheet into an Engaging Activity Lets face it, worksheets are not fun. To students, the mere presence of them means boring and for us teachers, they are just another thing that we have to give students to help them learn or reinforce a concept. But, what if I told you that you can take these boring worksheets and turn them into something fun, and something that would required no extra prep time? The Cornerstoneforteachers.com came up with 5 no prep ways that you can do this that are genius. Heres how. 1. Worksheet Cut-Up Place students into groups of five and give them one worksheet per group that has each question on the sheet cut up. For example, if your worksheet has ten questions on it, all ten questions would be cut up into a separate strip of paper. Next, students will each take turns choosing a role. The roles for the game are as follows: Person 1 - reads the questionPerson 2 - Paraphrases the question and may or may not offer a few cluesPerson 3 - Gives their answer and explains why they chose that answerPerson 4 - Agrees or disagrees with person 3 and explains their reasoningPerson 5 - Places the strip of paper into a pile that agrees or disagrees with the answer, then they take on the role of person number 1 for the next question. The roles continue to shift until all of the question strips are answered. At the end of the game, students look through their disagree pile and try to find some kind of consensus. 2. Everybody Agrees For this activity you must divide students into teams of four. Each team member is given a number 1-4. The teacher asks all groups the same question (from the worksheet) and gives teams a few minutes to come up with an answer. Next, you randomly call a number 1-4 and whoever is that number for each group must share their groups answer. This answer should then be written on a dry erase board to ensure that each answer is unique to the group, and that no one changes their answers. For each correct answer that group gets a point. At the end of the game the group with the most points wins! 3. Lines of Communication Have students stand in two lines facing each other. Choose one question from the worksheet and ask students to discuss the answer with the person that is across from them. Then, randomly ask any person to give an answer. Next, have students in one row move to the right so for the next question they will have a new partner. This goes on until all of the questions on the worksheet are completed and discussed. 4. Making Mistakes This is a fun activity that really gets students excited about learning. For this worksheet activity have students complete all of the questions or the problems on the worksheet, but randomly make one mistake. Then, ask students to exchange papers with the person next to them and have them see if they can find the mistake. 5. Classroom Rotation Have students move their desks so that all students are sitting in a huge circle. Then, have students count off so that each child is either a one or a two. Students then complete one problem on the worksheet with a person next them. When they are finished, call upon a random student to discuss the answer. Next, have all of the twos move down a seat so that all of the ones now have a new partner. Continue to play until the worksheet is completed. Looking for more group activities?

Select one topic - Essay Example Hence the term â€Å"ethnicity†. This paper looks behind the deep issues involved in the rise of the term â€Å"ethnicity† and why social scientists now prefer to use the term â€Å"ethnicity† over â€Å"race†. Various data and irrefutable information will be presented coming from peer-reviewed journals, books, and appropriate websites in order to explain how the change from â€Å"race† to â€Å"ethnicity† took place over the course of time. A look into the history of the study of human race and its evolution will show that the concept of â€Å"race† is something that can trace its early roots to the European slave trade. The concept itself is the result of a scientific revolution that emerged during the time of European imperialism and colonization. Due to the influence of people from various parts of the world upon European culture and social conduct, Europeans began to suspect that there were marked differences in the physical, social, and cultural awareness of human groups. It became their opinion that some human beings from particular parts of the world were of a higher physical, social, and cultural background than the rest. Therefore, a division between the people must exist. This division was meant to connote the higher group of people from those deemed more inferior. The term â€Å"race† was then coined in order to create a semblance of control over the African slaves using a type of mind conditio ning related to the term used to describe them or their â€Å"race†. With the widespread use of the term â€Å"race† across the globe, it became clear to social scientists that the term was used to define the real or imagined physical differences between people. The differences could be based upon visible and obvious differences such as skin color and physical appearance. Once a person is defined by his â€Å"race†, it then becomes his social identity which tends to influence social

The History of Women in the Struggle for America's Independence Essay

The History of Women in the Struggle for America's Independence - Essay Example The most unique aspect of the book was the apparent focus of attention on the contributions of the common woman. Berkin provided a brief acknowledgment of famous revolutionary women such as Martha Washington and Abigail Adams.1 She eventually focused on the core contributions of Native American, black and white women. Consequently, the result was a multifaceted gender revolution by American women. Colonial and Revolutionary Role of Women The colonial society associated the role of women with the traditional function of mother and wife. A majority of the colonial women believed that God created them as helpmates to man and nature.2 Furthermore, the woman was taught since childhood to be obedient, industrious, and faithful with the primary function of bearing and taking care of children. These roles were cemented by religious doctrines such as those by the Puritan divine Cotton Mather that taught women to be like an â€Å"Ornament of Zion looking upon (a husband) as her guide.†3 Later, a new ideal of femininity based on â€Å"pretty gentlewoman† shifted from that of â€Å"notable housewife.†4 The â€Å"pretty gentlewoman† was associated with cleanliness as the primary function and was assisted by slaves and maidservants. ... Among the first evidence of women’s activeness was to say â€Å"No† to colonial policies. This involved the denial to consume British merchant goods such as imported tea.6 Furthermore, the patriotic women followed their husbands to war with some assuming the role of â€Å"camp followers.† Their regular duties included cleaning and cooking for the soldiers.7 Moreover, some women such as Deborah Sampson fought as soldiers although in disguise. In addition, the author narrated about Margaret Corbin who provided water for cooling the cannons during combat and equally assisted the disabled husbands. African American women were more concerned with the quest for freedom and liberty. Consequently, they followed the Loyalist army of the British after being promised freedom from slavery. Evidence advanced by the author from the Philipsburg Proclamation stated, â€Å"†¦every negro who shall desert the Rebel Standard will be granted full security to follow within these , Lines, any occupation he shall think proper.†8 The Native American Indian tribes fought for the British since they hoped for independence and land rights.9 Consequently, it was the influential native women leaders such as Nanyehi and Queen Esther Montour that influenced the Indians into fighting for the king. The war placed a heavy price on the values of women involved in the revolution especially the camp followers. Berkin described the pathetic state in which the women lived and dressed. She illustrated the ragged state of their clothing which got worse as the women were forced to wear â€Å"the coats or shirts they removed from dead or dying soldiers.†10 Furthermore, women were given meager wages for their services.
