Bimolecular Nucleophilic Substitution and Organic Chemistry Teacher Resources

Bimolecular Nucleophilic Substitution and Organic Chemistry Teacher ResourcesAs is the case with all other life sciences, all teachers of organic chemistry should be provided with the Bimolecular Nucleophilic Substitution module. If you are not provided with this module, your students will not have a working knowledge of a practical scientific theory. Therefore, it is highly recommended that you provide this module to all your organic chemistry teachers.This module is known as the very basics of Bimolecular Nucleophilic Substitution, and because it is one of the simplest forms of the theory, many organic chemistry teachers are unable to teach it well in their Organic Chemistry classes. However, Bimolecular Nucleophilic Substitution is an important part of any technical theory. Once you have the modules, you should teach the module in all your lessons.This module can be learnt using a set of modules that are specially designed for teaching this theory. There are three modules availabl e that will teach the theory very clearly. The first is the Bimolecular Nucleophilic Substitution module, the second is the General Equilibrium Modules, and the third is the Introduction to Biomolecular Theory modules.You may choose to use one or two of these modules for your organic chemistry teacher, but if you do this, you will need to understand that Bimolecular Nucleophilic Substitution is an integral part of all theoretical chemical and physical principles. Therefore, to fully understand this concept, it is essential that you understand all aspects of chemistry as a whole. This involves the introduction of special chemical compounds that form the basis of organic chemistry, such as carbon atoms, and their substitution into the other elements, or the process of making new compounds, by the act of nucleation. The last of these two concepts, nucleation, is an essential element in the basic concepts of organic chemistry.organic chemistry tutor bimolecular nucleophilic substitution Nucleation is the idea that a compound could have a new form when a nucleus of a heavier atom is added to a compound. With the synthesis of manganese-based compounds, the method of nucleation was discovered. With this, one could make compounds containing a molecule of manganese, or another base like zinc, or even iodine.There is nothing more exciting than working with molecules of compounds that are completely different, and the experiment of taking the compounds, mixing them together and finally observing the result is a thoroughly rewarding experience. It is such an exciting discovery, however, that it needs a whole group of people, one of which would be the Bimolecular Nucleophilic Substitution module, and the last of which is the General Equilibrium Modules, which is used to give students an understanding of the dynamics of these compounds, and how they react with each other.Although this module is fairly easy to use, you will want to take the time to explain everything in det ail to your students in order to really make an impact. This is necessary so that the student understands the importance of the module and how it can benefit them in life.

Sampling Error Definition - Online Math Tutoring

Sampling Error Definition - Online Math Tutoring Definition:- Sampling error is the difference between the value of a sample statistic and the value of the corresponding population parameter. In the case of mean, Sampling error= x? - Assuming that the sample is random and no non-sampling error has been made. Note: - Sampling error occurs because of the chance. The difference between the values of a sample statisticobtained from a sample and the value of the corresponding population parameter obtained from the population is called the sampling error. Example: -There are only five students in an advanced statistics class and midterm scores of these five students are 70 78 80 80 95 Find the sampling error. Solution: - The population mean is = (70+78+80+80+95)/ 5 = 80.60 Now random sample of three scores from this population is taken and this sample includes the scores 70, 80, and 95. The mean for this sample is x?= (70+80+95) /3 = 81.67 Consequently, Sampling error= x?- = 81.67 80.60 = 1.07 Other example:-Consider the following population of 10 members. 20 25 13 19 9 15 11 7 17 30 Select one random sample size of five and calculate the sampling error. Solution: - The population mean is = (20+25+13+19+9+15+11+7+17+30) /10 = 16.6 Now random sample size of five from this population is taken and this sample includes the scores 20, 9, 11, 17, and 30. The mean for this sample is x?= (20+9+11+17+30)/ 5= 17.4 Consequently, Sampling error= x?- = 17.4 16.6 = 0.8

Ask a Law School Admissions Expert Derek Meeker

Ask a Law School Admissions Expert Derek Meeker Varsity Tutors brings you insider tips and advice straight from nationally recognized admissions experts. Derek Meeker is the Founder and President of Dean Meeker Consulting, a law school admissions consulting company. Derek previously held the role ofDean of Admissions and Financial Aid for the University of PennsylvaniaLaw School. He has also served as theRecruiting Manager for the global law firm, Paul Hastings, and as an admissions reader for The University of ChicagoLaw School. VT: How much time should be set aside to adequately prepare for and complete a Law School application? Derek: The amount of time it takes to adequately prepare for and complete a law school application is anywhere from six to ten months. Applicants must give themselves several months to study for the LSAT, and preparing for and taking the exam should (ideally) be done before the application season opens (i.e. prior to the fall). That way, applicants can focus solely on the other components of the application during the late summer and fall months, as they likely will also be juggling school and/or work obligations. Applicants also need to arrange for letters of recommendation, and they should give their references at least two to three months advance notice. Professors will be much busier in the fall and may be difficult to reach during the summer, so, again, planning several months in advance and well before the admissions season opens is ideal. Finally, the personal statement is a crucial component of the admissions process, and most applicants find writing a personal statement to b e extremely challenging; thus, allowing a couple of months to brainstorm topics, write several drafts, get feedback, and tailor the essay for various schools is essential. There are several other administrative steps (e.g., requesting and submitting transcripts) and written components (application forms, resume, and possibly supplemental essays or addenda) that will also add to the timeline. VT: What is the single most important thing applicants should focus on with this application? Derek: Aside from LSAT preparation, the single most important thing applicants should focus on is superior writing in all components of the application (i.e. the application form, personal statement, supplemental essays, resume, and any addenda). Writing is the single most important skill for success in law school and for success as a lawyer; everything you submit as part of your application will be a measure of your ability to write effectivelyi.e. in a way that is descriptive, informative, and compelling, yet also cohesive, concise, and genuine (and, of course, grammatically impeccable!). VT: What are the biggest mistakes one can make on a Law School application? Derek: Aside from the obvious mistakesgrammatical errors, typos, failing to follow instructions, or failing to respond to required questionsone of the biggest mistakes one can make is writing the personal statement as a mini biography, or taking the admissions committee on a resume tour, as I like to call it. I always advise applicants to complete the resume before writing their essays. (And note, a two-page resume for the application is perfectly acceptable, unless the instructions specifically state otherwise.) Writing a detailed resume will paint a broad picture of your academic, work, community, and extra-curricular experiences; use the personal statement and supplemental essays to delve more deeply into specific experiences or to present valuable information that may not be apparent from other parts of the application. Another big mistake that applicants make is submitting the same exact personal statem ent to every school to which he or she is applying. Simply changing the name of the school in every essay (or worse, forgetting to change the name of the school!) is not advisable, particularly for highly selective or reach schools. What often separates similarly competitive applicants from one another is the extra effort or personal touch that one puts into his or her application. Show through your essays the unique perspective you would bring and contribution you would make to that particular law school. Show that you have done your research on the school by discussing why it is a good fit for you personally, academically, and professionally given your values, interests, and career goals. (Note, some schools provide this opportunity through optional supplemental essays; do the supplemental essays.) Putting in that additional effort will make your application stand out because it will convey that you are genuinely interested in the school, focused and goal-oriented, and, thus, more prepared for law school and legal practice. VT: What do Law School admissions officers look for most in an applicants essays/personal statements? Derek: My advice for the personal statement is: be who you are and share who you are. As the Dean of Admissions for Penn Law School, I always asked when reading applications, What voice will this person bring to the classroom? How will he or she contribute to the law school community and to the legal profession? Two of the most common questions I hear from applicants are: But theres nothing unique about me; I grew up in a middle-class suburb, went to fine schools, didnt have to overcome significant challenges, etc. What could I write about that would be interesting? Or, at the other end of the spectrum, But dont a lot of people write about their challenges as a first-generation American (or being raised by a single-parent, or spending time abroad to study or work)? The personal statement is about youyour experiences, your achievements, your challenges, your goals. It matters less what the topic is (e.g., whether it is common) and more how you write about it. What did a particular exp erience or challenge mean to you? How did it affect, influence, inspire, or teach you? What decisions have you made or what actions have you taken as a result? How will you affect, influence, inspire, or teach others as a result? It is a personal statement, so make it personaltake the reader into your experiences through clear, vivid, and descriptive prose. As long as you write about something that is meaningful to you, about which you genuinely feel passionate, and that has somehow shaped you or defined your goals, it will be compelling. VT: Is there anything on a students application that would automatically disqualify them from being considered for the program? Derek: Providing information that is dishonest or failing to write an addendum that adequately explains a criminal record or academic misconduct could lead to automatic disqualification. VT: What about the Law School admissions process differs the most from undergraduate admissions? Derek: Because you will be applying for a professional degree, it is important for the law school admissions committee to understand why you are interested in attending law school and what your career goals are (at least, generally). In this regard, the information you submit needs to be more specific. Law schools expect their applicants to be more mature and focused, to have a deeper awareness of themselves, and a broader awareness of the world in which they live. Also, very few law schools offer the opportunity to interview, something that is much more common in the college admissions process. VT: What kinds of things (experience, grades, etc.) might a student lack that would lead you to advise them not to apply? Derek: Maturity, focus, and a keen understanding of what law school entails and what it will cost them, as well as an understanding of what lawyers do and earn. Law school is expensive and the current legal market is extremely competitive. It is absolutely imperative that students understand what career opportunities are likely to be available to them from the schools at which they will be competitive (i.e. what the return on investment will be). Also, having spent the last four years as the Recruiting Manager for a large law firm, I highly encourage students to get some full-time work experience before enrolling in law school. While it is not required, substantive work experience will make them more compelling as candidates for attorney positions and more prepared for the rigorous work ahead of them. VT: Is there anything you might see on a students application that would quickly put them ahead in the running? Derek: The admissions committees goal is to put together a class of students that will engage, challenge, and teach one another through their diverse backgrounds and perspectives. Thus, anything that is distinct or unusual relative to the overall applicant pool (e.g. a particular course of study, job, or accomplishment, geographic background, cultural upbringing, a personal hardship or significant challenge, etc.) will immediately stand out. One of my favorite stories from my time at Penn is when I called an applicant to tell him that he had been admitted. Apparently in shock, he replied, Why did you admit me? And I said, Because you grew up working on a ranch in Montana. Now, I distinctly remember that that applicant did not have as high a numeric profile as the majority of applicants admitted to Penn. But what put him ahead of the running is that he brought a perspectiveone that he effectively articulated in his applicationthat was not represented in the student body. VT: What advice do you have regarding LSAT test prep? Derek: How much time it takes to sufficiently prepare for the LSAT varies greatly from applicant to applicant. What is important to note is that you will not know how much time you need to adequately prepare until you start taking practice exams. You also may not know what the most effective method of preparation will be for you until you are in it. Some applicants will find that studying on their own by using resources that are available through LSAC is sufficient; others may feel a classroom environment would be more effective and will want to take a prep course. Still others may learn best by working one-on-one with an LSAT tutor. The cost of each of these methods also varies greatly. Thus, my advice is to begin preparing and taking practice exams many months before you plan to take the LSAT so that you have adequate time to determine the method of preparation that works best for you, and to save additional money or make scheduling adjustments, if necessary. VT: What do law school admissions officers look for in recommendation letters? Derek: Admissions officers expect the letter writers to know the applicant extremely well from an academic setting, employment setting, or, perhaps, through substantive community service or extra-curricular activities. The letters should include specific and detailed examples that illustrate the applicant has the skills or characteristics that are necessary for success in law school (and as a lawyer), such as outstanding writing, oral communication, advocacy, analytical, and critical reading and reasoning skills, discipline, perseverance, confidence, maturity, focus, adaptability, judgment, and attention to detail. A diverse portfolio of letters (i.e. letters that provide unique perspectives on the applicant) is ideal. Visit Dean Meeker Consulting for more information.

The Coordinate Plane

The Coordinate Plane A two dimensional coordinate plane is a surface on which there are two axis perpendicular to each other, the horizontal axis known as the X-axis and the vertical axis known as the Y-axis. On the basis of these two axis, points are plotted on the coordinate plane. The point of intersection of the X-axis and the Y-axis is known as the origin and the point of origin is (0, 0). The coordinate axis divides the coordinate plane into 4 quadrants known as the first, second, third and the fourth quadrants. Example 1: Given 2 points, (1, 2), (-2, 4). On the coordinate plane, in which quadrants do the points lie? The coordinate plane is divided into 4 quadrants as shown above. The point (1, 2) - x = 1 and y= 2. Since both x and y are positive numbers, the point lies in Quadrant I. The point (-2, 4)-x= -2 and y= 4. Since x is negative but y is positive, the point lies in Quadrant II. Example 2: Given the points, (-3, -1), (5, -6) and (-4, 5). On the coordinate plane, in which quadrants do the points lie? The point (-3, -1)-x= -3 and y= -1. Here both x and y are negative, hence the point lies in Quadrant III. The point (5, -6)-x= 5 and y= -6. Here x is positive and y is negative, hence the point lies in Quadrant IV. The point (-4, 5)-x = -4 and y= 5. Since x is negative but y is positive, the point lies in Quadrant II.

How the Violin is Played in Asia

How the Violin is Played in Asia Asian Violin Practices ChaptersString Instruments in AsiaThe Violin Around AsiaEstablishments for Learning the ViolinThe Greatest Asian Violinists“We are well aware that the future of classical music is in Asia” - Didier Schnorhk, President of the World Federation of International Music Competitions.Playing the violin (or fiddle) is wildly popular in Asia. Asians represent 47% of entrants and 35% of winners in violin competitions such as the Yehudi Menuhin International Competition for Young Violinists.Of course, the violin and other string instruments like the cello and viola aren’t thought of in exactly the same way across the whole continent. In this article, we're going to have a   look at the ancient practices, how the violin differs from region to region, and how people learn to play the violin in Asia.

While the violin first appeared in Cremona, Italy, in the 15th century, there was already a long history of bowed stringed instruments by other names on the Asian continent.Asia has its own instruments and culture, too. (Source: NeuPaddy)In a lot of countries, there are instruments similar to the violin being played:In China, the erhu is common. It has an open sound box which is often covered with snakeskin. The soundboard is a wooden plank and the strings are made of hairs which are vibrated with a bow.In India, they play the vînâ, a musical instrument that’s very common in traditional Indian music.In the Middle East, the vielle is commonly played, though it's slightly different in each country.In Japan, they play the kokyu is popular. This is like a vielle and a blend of a traditional Western violin and the Chinese erhu and is Japan’s only bowed instrument.It should be noted there have been many a disagreement between luthiers. While Europeans traditionally made the best luthiers, with big names such as Antonio Stradivari and the Guarneri and Amati families, there’s a lot of competition coming from China. Pinggu, a city near Beijing, is home to many luthiers selling violins sold outside of the country. 70% of Geng Guosheng’s sales are to countries other than China.Stradivarius isn’t the only brand of violin you should be thinking about. It's all down to what a musician prefers, after all. Additionally, if you can't play the violin, any violin will sound terrible.An Asian soloi st won’t have the same training and understanding of music as a European soloist. For example, an Asian violinist may not have grown up listening to Paganini, Bach, Mozart, etc. so their musical reference points and their teachers won’t be the same. The same is true for the sound. The violin is different all over Asia.The Violin Around AsiaAsia includes many different countries: 47 in total and the majority of Russia. This means you can’t generalise when talking about the violin.Each country in Asia has its own way of playing the violin. (Source: Free-Photos)The Violin in Southeast AsiaThere are musical influences from the following countries:IndonesiaMalaysiaThe PhilippinesSince these countries were colonised by European empires, you see the violin pop up again and again. The inhabitants of these countries are more familiar with the biola, a local variation of the violin brought by the Portuguese and the Spanish, than chamber music and symphonic orchestras.The Violin in the M iddle-EastThe violin is quite famous in the region where the violin is a part of most countries’ traditional music. We’re talking mainly about the following countries:IranIraqTurkeyIsraelJust like in North Africa, you can find Gyspy music influences. The violin, as well as the kamancheh, djoza, kemençe, and the folk violle, is played on your legs or knees without a shoulder rest or chinrest.The violin is very common in classic Turkish music as well as contemporary popular music. The violin is regularly practised and is taught in music schools just like it is in Europe and it's quite easy to see a symphony orchestra or hear a violin concerto.Passion for the Violin in China, Korea, and JapanWhile the Chinese empire seems to have used traditional bowed instruments from as early as the 8th century, Japan and Korea would take longer to adopt them. This grew from competing musically with Europe and other continents.Learning the violin and modern music training requires discipline and work, two things that are considered very important in this part of the world. As Didier Schnorhk said in South Korea, “There has been a willingness to invest in general education and culture, in particular. Incredible music schools have opened, they’ve welcomed the best teachers from abroad, and created structures which help spread culture.”These plans seem to have had a positive effect.So where can you learn to play the violin in Asia? Where can students become famous violinists?Establishments for Learning the ViolinIn order to learn the violin, you need exceptional training, music theory lessons, and a lot of practice. The main places to get all this are conservatoires and universities.Students go there to learn how to become violinists and will get training on different types of violins and can train regularly with string quartets and orchestras.A lot of Asians come to Europe to learn more about the violin. (Source: 4997826)The best way in Asia to become a violinist is to attend higher education establishments such as conservatoires, specialised music schools, and universities. You’ll be able to improve your playing abroad as well as get the opportunity to enter international competitions if you’re good enough.The most reputable establishments across Asia for learning to play the violin are:The Korean National School of Music in South KoreaThe Delhi School of Music in IndiaThe Khoshnahad Peiman Conservatoire in IranThe Bechmann-Mehta School of Music in IsraelThe Aichi Music School in JapanThe Kuala Lumpur International College of Music in MalaysiaThe Taiwan Normal University College of Music in TaiwanThe Istanbul Mimar Sinan Conservatoire in TurkeyThe Conservatoire of Hanoi in VietnamDid you know that 23% of violinists trained in Europe are of Asian origin?Each year, Asian violinists attend European institutions in order to complete their violin training. This allows them to get a similar musical training to the greats like Beethoven, Brahms, St ravinsky, and Profokiev.The Greatest Asian ViolinistsNot all violinists are created equal. Playing in a philharmonic orchestra or a national orchestra will definitely increase your chances of being one of the greats. That said, there’s still a huge number of Asian violinists winning international violin competitions.There are tonnes of famous Asian violinists. (Source: 6335159)Looking for a good performer?Here are some of the greatest Asian violinists:Ray Chen. A violinist from Taiwan has perfectly mastered modern violin techniques.Kyung Wha Chung. A famous violinist from South Korea.Vanessa-Mae. A classical Chinese-Thai violinist who became famous from a young age.Nedim Nalbantoglu. A violin prodigy from Turkey.Lakshminarayana Subramaniam. An Indian advocate of multicultural violin playing.Kayhan Kalhor. The Iranian king of the violin.How long does it take to become a great violinist?The average age of violinists, not including child prodigies, is 33. Of course, that doesn't mean that you can't learn to play the violin if you're over this age.When we consider conductors, too, there’s also:Jing Huan. A young woman from Beijing.Myung-Whun Chung. A holder of the prestigious Kumkuan award whose both a pianist and violinist.Despite the historical, social, and cultural differences, violin playing in Asia shares a lot of similarities with Europe. Additionally, the traditions of both continents are available to everyone.After all, music is international, isn’t it?Would you like to learn how to play the violin, become a violin virtuoso or composer, and see these great violinists live?If you can't make it all the way to Asia, don't forget there are private tutors available in the UK such as the tutors on Superprof. Since you're a tutor's only student (in that class), they can tailor all the lesson to you.Additionally, a large portion of the tutors on Superprof offer the first hour of tuition for free. This is a great opportunity to talk to them about how they tea ch, what they can teach you, and just to see if you get along. Whether you want to learn the violin for fun, get into a prestigious music school (in Asia or elsewhere), or become a professional violinist, you can find a tutor to help you work towards your goals.For those who live rurally or have a work schedule that doesn't allow them to get regular violin lessons, there are always online private tutorials via webcam. These are often cheaper than face-to-face tutorials as the tutor doesn't have to cover the cost of travelling in their rates.Violin is played creatively around the world, read more regarding how the violin is played in Africa or how violinists  play in America  and the influence of the violin in Europe.
