Does It Matter If Its Expensive?

Does It Matter If It's Expensive?Let me introduce myself, a man of the middle class and my enthusiasm for the book Ted Greene, et al. has brought to the world... 'Chemistry, PDF' by Dr. Deborah Isay.Dr. Isay's methods are a great deal simpler than I would have had them before reading 'Chemistry, PDF'. I would have had to learn through trial and error as well as what I had learned from other teachers I have seen. And, that is just not enough, especially when it comes to this subject! And then, of course, there was the inability to find the time.Dr. Greene, et al. can be a little slow in making their material available to their students. In a way, that is fine. A little impatience does not hurt anyone.What I am questioning is the need for such an expensive course as 'Chemistry, PDF' by Dr. Deborah Isay and Ted Greene. In fact, I have noticed that such courses as those 'Molecular Dangers'Your Life at Risk' by the American Association of Clinical Chemistry are much more affordable.These classes present an easy introduction to chemical preparation that covers all the basics and can be completed in about two hours. To be fair, most of the content of these courses is very similar, but the information is presented in a different format so it can be taught in a shorter period of time.If you are a student of organic chemistry course, I suggest you review the material of 'Chemistry, PDF' before you look for more advanced materials. However, that might be asking too much. It can still be fun to take the easier courses for such subjects as the Introduction to Organic Chemistry and the Organic-Organic-Metabolism course, if you feel it is necessary.I guess I like teaching because I love life science. So, whether a student is very young or very old, I think it is important for a teacher to be able to communicate with students. I think the older teachers are a bit more tired from teaching their students for a long time.Also, I am more likely to try something new with my student s if I have been working with them before. That is why I am more likely to suggest new ways of doing things instead of repeating what I used to do. So, although Dr. Greene is a great choice of author, I do not recommend the more expensive courses.

Learn About the Benefits of Joining Schools With Sorts of Lessons

Learn About the Benefits of Joining Schools With Sorts of LessonsIn the case of a student who would like to have a practical experience, and who would like to feel how schools would help them, enrolling in beaches tutoring can be very helpful. It will not only give the student an idea about the educational system, but also help them understand that it is not all about academics and memorization. This allows them to understand that they can actually do something that will benefit them.Even though a child is young, there will still be a certain character or particular personality that he has, and that will serve as an indicator for him when he goes to school. When you are enrolled in beaches tutoring, you can already get a peek of his character.When a child goes to school, there are various responsibilities that will come up that will involve him. The most important one being, learning how to organize your time and prepare yourself for the next lessons. This is the first task that you have to do, and this will serve as a result of which, your mind will be fresh and clear, and you will also realize that you are able to learn more quickly when you have your own hour to do things. And this will make you realize that you are doing something that will serve as the basis for your life and future.As soon as you are done with beaches tutoring, you will realize that you have learned a lot about the ins and outs of school. Now you are able to continue with your studies and master what will not only help you prepare for school, but also will teach you things that will help you apply. The day that you are done with beaches tutoring, you will have mastered many things, such as building up a good relationship with your teachers, and also how to win over your classmates, etc.It will also help you learn how to do a good job in school, because your guidance counselor will tell you all the tips, and the tips are very important if you want to become a good teacher. Besides, when yo u are prepared, you will be confident in your skills and will not let anything frighten you when the students are always struggling and bothering you. But just in case, when you know how to handle yourself when you have the responsibility of managing the students, you will know how to deal with the difficult situation.Beach tutoring is important for students who do not have the time to go to school everyday. Even though you will be in the school with your classes, it will still help you to focus on your classwork, and thus your studies will also improve.Finally, the beaches tutoring can even help you earn extra money, especially if you do well. However, you will have to help them get good grades, so as to help them earn more money. Since they are working at the same company, they will need to learn to work together as a team to accomplish the task, and this can help them to learn about teamwork and problem solving.

Why Does College Algebra Story Problems Helping Students?

Why Does College Algebra Story Problems Helping Students?College algebra story problems help students who find themselves stuck in the difficulty of a homework assignment. What follows is an explanation of how math problems make homework much easier for most students.The first thing to keep in mind about homework is that it should never be the end of the story. Students should be encouraged to do more than just complete the assignment. In addition to completing the task, they should also learn from the assignment as well as how it can help them to progress toward a future goal.Since math problems are often presented in a very visual manner, it is very easy for students to understand the most effective ways to solve them. It is not as easy to understand them if the solution is done by recalling different algorithms or formulas.Find a simple and short form of the problem. Think of one of the most obvious solutions to the problem. Then get to work on that. Make sure that the solution us ed is not too complicated, but simple enough to have students see how it fits into their conceptual understanding of the problem.Since algebra is a difficult task to learn, many students will naturally want to avoid the difficulties they have to face by doing the most efficient way to do the assignment. If you use this strategy, you can usually trick students into thinking they have solved the problem, but it is not true. They only did one thing-they learned that they could do the best solution to the problem.When students are faced with challenging assignment problems, they are usually looking for a shortcut. They know it is very difficult to solve a problem by visualizing the steps needed, so they turn to algebra. They are basically seeking a formula that they can always refer to when they need the answer.These students do not appreciate the challenge they are facing because they have forgotten the challenging and difficult things that make it so. In college, they are still learni ng the most important things and they are naturally curious about difficult tasks. College algebra story problems help students to make themselves a step ahead of their peers.

How LSAC Calculates Your GPA

How LSAC Calculates Your GPA The Law School Admission Council (LSAC) calculates your likelihood of attending law school by examining your LSAT scores and your undergraduate GPA. Here is some great information on how the LSAT is scored. There are a number of websites that allow you to enter your GPA into their virtual calculators. While each law school typically does not adhere to a strict minimum for LSAT results and GPAs, there are general thresholds that programs desire. Your testing date, professional experience, and ethnicity are not taken into consideration when determining your personal index score. Here is are6 tips to help you excel in law school, which you my find useful in the future. How is my LSAC GPA determined? The official LSAC GPA calculator provides applicants with an estimated score for their admissions index (an index score). While each law school calculates this admissions index differently, the LSAC official calculator is an ideal place to begin, as it maintains a number of potential index formulas. The LSAC grade scale is somewhat different from that of many undergraduate schools. An A+ (98-100) is worth 4.33. While the scale is based upon the normative 4.0 GPA scale, it allows for an A+ grade. It does not, however, award credit for an E or F. Non-punitive withdrawals on your transcripts are not included as failing grades within your LSAC GPA. All other withdrawals are noted as failing marks (0.00). Note that passing grades in a pass/fail class will not be calculated in the LSAC GPA. If you enrolled in a course twice, both the original and retake result count, even if your undergraduate school only utilized the second score in your GPA. If your study-abroad courses do not appear on your domestic transcript, they will not be counted. Here are 3 ways extracurricular activities help your law school applicationas well. Generally, if a grade is present on your transcript, it is likely to be included in your GPA. This is true only of classes prior to earning your first Bachelors degree. If you have completed coursework after this stage, it will not be taken into account when calculating your index score. What should I do with my index score? With your score in hand, there are a number of sources that offer matching services between your index result and various law schools. Several focus solely on top-tier programs. Not all services are reliable, so ensure you do sufficient research when investigating these matches. With luck, they will guide your application process to law schools within your reach, as well as save you money and time in determining which programs are best for you. Consider limiting reach schools to just one application. Also keep in mind also that if you have sat for the LSAT multiple times, law schools receive every score report. Prepare accordingly, and good luck!

Definition of Perpendicular Lines

Definition of Perpendicular Lines We can define perpendicular lines are lines, which have angle between them are right angle (90O). In other words we can say perpendicular lines are lines, having product of slopes -1. Means if the slope of a line is 2, then the slope of perpendicular line is (1/2). If we have line ax + by + c = 0, we know the equation of perpendicular line bx ay + k = 0. Problem 1: If we have a equation of a line 3x - 4y + 7 =0, find the equation of a line which is perpendicular to the given line and passes through (1, 0). Solution: Step1: The equation of given line is 3x 4y + 7 = 0 = Step2: The line perpendicular to 3x 4y + 7 = 0 is 4x + 3y + k =0 = Step3: We know, this line passes through (1, 0), so we need to plug the values in this equation to get the value of k = 4 (1) + 3 (0) + k = 0 = k = - 4 = Step 4: The required equation of a line is 4x + 3y 4 =0. Problem 2: If we have an equation of a line 2x + 3y + 4 =0, find the equation of a line which is perpendicular to the given line and passes through (1, 1). Solution: Step1: The equation of given line is 2x + 3y + 4 = 0 = Step2: The line perpendicular to 2x+ 3y + 4 = 0 is 3x 2y + k =0 = Step3: We know, this line passes through (1, 1), so we need to plug the values in this equation to get the value of k = 3 (1) 2 (1) + k = 0 = k =- 1 = Step 4: The required equation of a line is 3x 2y - 1 =0.

The Life Cycle of a Star.

The Life Cycle of a Star. From a Dust Cloud to a Black Hole, Here’s What You Need to Know about a Star’s Life Cycle. ChaptersWhat is a Star?How is a Star Formed?What are the Stages in the Life of a Star?What Happens Next? It Depends on the Size of the Star.Look up into the sky. That thing shining there â€" or ‘burning ferociously’ as might be a better description â€" has been doing its thing for four and a half billion years. Throughout the course of human history, it’s been there the whole time, burning away and giving life to our planet.4.6 billion years. That’s a number that we can hardly even imagine. Yet, scientists reckon that our Sun is about halfway through its lifecycle.Give it another four billion years and it will, like all stars do, ultimately ‘die’ â€" changing from a main sequence star into a supernova or into what is known as a planetary nebula. We ain’t gonna be alive to see any of this happen â€" and, by we, we mean planet earth.Here, we’re going to be talking about the life of a star. We’re going to be talking about the forces that bring it together and that forc e it ultimately apart. And we’re going to be talking about the things that help it keep its shape and size for the unimaginably long time that occurs in between.We’ll be talking about those things with which you’ve probably heard in passing: the red giant, neutron stars, black holes â€" and white dwarfs and supernovas.All of these things make up phases in the life of a star. But let’s take a closer look.In the meantime, find out everything about astronomy, and the differences between astronomy, astrophysics, and cosmology. The sun is the centre of our solar system - not the Earth PetarPhysics Teacher 5.00 (11) £40/h1st lesson free!Discover all our tutors MyriamPhysics Teacher 5.00 (13) £20/h1st lesson free!Discover all our tutors Dr parikhPhysics Teacher 5.00 (8) £40/h1st lesson free!Discover all our tutors RubenPhysics Teacher 5.00 (1) £15/h1st lesson free!Discover all our tutors FrankPhysics Teacher 5.00 (8) £90/h1st lesson free!Discover all our tutors JidePhysics Teacher 4.80 (5) £30/h1st lesson free!Discover all our tutors DorothyPhysics Teacher 5.00 (5) £40/h1st lesson free!Discover all our tutors RahulPhysics Teacher £20/h1st lesson free!Discover all our tutorsWhat is a Star?Now we’re all quite familiar with the Sun â€" from a distance at least. And, unless you live in the biggest of cities and have never looked up, it is pretty likely that you will have seen some stars in your life too.But do you know what a star actually is? Apart from the fact that it ‘twinkles’ and is in ‘the sky’.A star is a massive object in space, held together by gravitational forces, that is distinguished from a planet by its luminosity â€" or the fact that it produces light.That’s the short answer. Now to the long answer.A star is a ball of plasma and gas that radiates energy in the form of heat and light. This radiation is due to the thermonuclear fusion of hydrogen into helium that occurs at its core.All this wouldn’t happen if stars weren’t so big. But, under the force of gravity, and under all sorts of other molecular forces, atoms are smashed together, and new elements are formed. All of this releases energy. This process, which we call nuclear fusion, is, incidentally, something we hope to replicate on Earth â€" because of the sheer amount of energy that it produces.But no, stars aren’t really ‘burning’ or ‘on fire’ or any of these words we use to describe them. Rather, the processes that are happening mean that the sun is much hotter and much more en ergetic than any fire we’ve ever seen.Learn more about our solar system!How is a Star Formed?But why does all this happen? One of the most amazing things about our universe is that there is anything at all in it. As the philosopher Gottfried Wilhelm Leibniz once asked, how come there is something rather than nothing? This question is a little relevant when it comes to thinking that stars produce the very conditions that support life.Nebulae.Imagine an empty, desperately cold space filled with dust and gases that are the debris of old planets and stars. Star formation begins when, in this intense cold, all of this interstellar dust and gas slowly starts to clump together. Gases reach higher densities in the cold, whilst the atoms bind together.This is the first step in the life cycle of stars: the planetary nebulae, these molecular clouds that drift across the universe.As soon as higher densities are reached, the gravitational forces get stronger, meaning that all of the gases and particles in the nebula slowly start coming together. These great big molecular clouds then start collapsing and, as they start moving in on each other, the heat increases.With all this stuff clumping together, the core becomes what will later be the star â€" or often even two or three stars known as star clusters. Meanwhile, different parts of the cloud might become planets or might just stay as dust â€" as in our solar system.(All of this, by the way, takes about ten million years. As a comparison, humans have been about for only two hundred thousand years.)Learn about some of the major astronomical discoveries. Nebulae are some of the most beautiful things in the universe.What are the Stages in the Life of a Star?So far we have seen how stars are created â€" from the big messy clouds of dust and gas in the universe. But what these nebulae create are hardly even stars just yet. Rather, they are protostars, which are the very beginning of the star life cycle.Protostars.After the initial phase as a nebula, the start of stellar evolution is in the protostar. This is when the star is essentially still growing â€" when it is still gathering dust and material from the cloud that formed it.The protostar begins with only one percent of the mass of its future self. But, with all of the mass that is ‘infalling’ due to the core’s gravity, it builds up relatively quickly.Only when thermonuclear fusion begins at the core does the star stop being a protostar and becomes instead a main sequence star. At this point the star’s mass is stable â€" as it produces a ‘stellar wind’ that prevents the i nfall of further mass.Brown Dwarfs.If protostars don’t become big enough, however â€" and by that we mean about eight percent of the size of the sun â€" they never really become stars at all. Instead, they become brown dwarfs, sort of failed stars in which thermonuclear fusion does not take place.Find and take classes with a maths physics tutor here.What Happens Next? It Depends on the Size of the Star.After the protostar stage, the nature and processes of a star’s life cycle depends on the particular star’s mass. And so we’ll split this here into two separate streams.There are those stars that have roughly the mass of the Sun â€" the sun being fairly ‘normal’-sized as far as stars go. Then there are those that are much bigger. The bigger stars are, the quicker they burn. So, whilst Sun-sized stars remain as main sequence stars for about ten billion years, a massive star would live less long.Even so, about ninety percent of a star’s life is as a main sequence star â€" in which it will casually fuse hydrogen into helium. When the hydrogen in its core runs out, the core will begin to collapse and will get much hotter.As the core increases in heat, it pushes the rest of the star outwards, meaning that the outer edges cool.Stars the Size of the Sun â€" Roughly.The most commonly sized stars are stars the size of the Sun. After about ten billion years, once they have run out of hydrogen, they slowly become white dwarfs.White Dwarfs.White dwarfs are cool little things that have perplexed scientists despite their commonness. Imagine the mass of the sun all in the space of the earth and you’ve got yourself a white dwarf. And bizarrely, they are denser the smaller they are â€" meaning the bigger stars would form the smallest white dwarfs.They are hugely dense things that keep themselves from collapsing further due to the activity of electrons. However, with no way of producing energy, there is nothing really that keeps them together. So, gradually coolin g, they just tend to fade away.Massive Stars.Massive stars have a different end in store for them.If a star is about eight times bigger than the sun, you can expect it to end in a massive explosion known as a supernova.Remember that the bigger the star the quicker they burn through hydrogen. And when they have run out of hydrogen, they produce iron as the result of a long series of chemical reactions. When that happens, the core collapses in a matter of seconds from five thousand miles across to just twelve.Temperatures reach a hundred billion degrees and the supernova becomes brighter than a whole galaxy. This is the first picture ever taken of a black hole.What is a Black Hole?Particularly dense stars produce one of the most fascinating phenomena in the universe when they die. These are black holes.Rather than exploding outwards, these stars implode, collapsing into themselves to form an object so dense that nothing â€" not even light â€" can escape it.These things pull everything around them into themselves â€" whilst emitting huge amounts of radiation.Is there life in the universe?

What is it Like to Attend Vassar College

What is it Like to Attend Vassar College The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Logan is a New York City tutor specializing in SAT prep tutoring, History tutoring, Algebra tutoring, and more. He graduated from Vassar College in 2012 with a Bachelors degree in Political Science. See what he had to say about his undergraduate years: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Logan: Vassar is located in Poughkeepsie, which is a medium-sized town in Dutchess County, NY, about an hour and a half north of the city. The campus is both beautiful and safe, and most of the students stay on it year-round. For those who do like to venture off campus, there are many reasonably priced, high quality restaurants within walking distance, and the surrounding area is safe and well lit. In terms of transportation, the only potential challenge is getting from campus to the Poughkeepsie train station (and vice versa). I was lucky enough to have a car and live within driving distance, so I am not completely familiar with the methods used to make that particular trip. From what I gathered, a lot of people used the taxi service, which Ive heard was fairly reliable. VT:How available are the professors, academic advisers, and teaching assistants? Logan: All of the professors I had were readily accessible outside of the classroom and very responsive to emails. Most of my classes were small enough (25 students at the very most) that I could typically converse directly with the professor, rather than a teaching assistant. The one teaching assistant I had taught a language class, and he was friendly and easy to communicate with. With regard to advisers, you will have one adviser when you enter as a freshman, and then you will switch to someone in your department when you declare a major. I actually changed majors my junior year, so I had three advisers at various points throughout my stay at Vassar. All three were responsive, knowledgeable about the graduation requirements, and accommodating to my needs and preferences. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Logan: I lived in one dorm (Cushing) my first two years, and in town houses my last two years. Cushing was a bit removed from the area which contained the four major dorms (Lathrop, Raymond, Josselyn, and Strong). While this separation did make it a bit less convenient to hang out in the residential quad, it did foster a sense of community within the dorm itself. I remained good friends with some of the people I knew from my earliest days at Vassar. The terrace apartments and town houses are where most people go when they become upperclassmen, with more moving into the latter. A typical TA or TH consists of 4-5 people who were friends and signed up to live with each other. My experience, however, was a bit different my first year living in a town house. I chose to take an opening in a TH with four people who I did not know at all. They were very friendly and welcoming, and they included me when they hung out with their broader group of friends. It was a great experience, and I still hang out with some of the people in this broader group who live near me today. My final year on campus was a bit more traditional. I moved into another town house, this time with people who I knew beforehand. Again, I had a very pleasant experience. One of the people with whom I lived was a tremendous cook, and would guide us in creating house meals which we enjoyed multiple times a week. Living with these people deepened my friendships with them, and I am tremendously thankful for the opportunity I had to do so. In general, if you live with friendly, responsible people (of which there are many at Vassar), your upperclassman experiences will be great and memorable. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Logan: Vassar is traditionally known as a more humanities focused Liberal Arts school, though its Science and Math programs are strong as well. I actually began as a Math major before switching to Political Science my junior year, so I have had both an atypical Vassar experience, and a more standard one. Both of these areas were well supported, and the teachers I had were tremendously knowledgeable and uniquely witty and humorous. I actually switched away from math after taking Modern Algebra (group theory) because it was too difficult and involved. That program will provide a challenging and engaging curriculum for even the strongest math student. And the more traditional majors are as excellent as advertised. VT: How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Logan: I transferred to Vassar after spending a semester somewhere else, so my freshman experience was atypical. I found it fairly easy to make friends, however, and I am not the most outgoing person. Because of the tremendous diversity in interests and backgrounds of the students there, it is not hard to find likeminded people, as well as people who are completely different from the ones you grew up with and who will broaden your social experience. There is no Greek life on campus, but there are plenty of social events. Some are of the all-campus variety, and are usually held annually/bi-annually at certain locations, while others are smaller functions geared toward specific student subcultures. In general though, it is a pretty inclusive campus, so if you are looking to socialize in a positive manner, there are ample opportunities for this. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Logan: This is the area about which I know the least. I decided to go to graduate school full-time immediately after college, so I did not get started on my professional career until I was a year and half removed from Vassar. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Logan: The Vassar library is large and notably beautiful. There are plenty of areas for both private, quiet study, as well as for group projects and discussions. The dorms also have study rooms that are readily accessible. Because it is a relatively small college population, the study areas are rarely over-crowded. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Logan: Again, Vassar is located in Poughkeepsie, New York, which is a reasonably safe, medium-sized town. There are many quality, affordable restaurants nearby, and there are a few bars throughout Poughkeepsie that are popular with the students (e.g. Billy Bobs, Mahoneys). In the broader Dutchess County area, there are a lot of historic sites such as the Vanderbilt Mansion, Franklin Roosevelts childhood home, the Beekman Arms (the oldest inn in the country), and others, which are all easy to get to if you have a car or know somebody with one. Vassar is close to other famous colleges and universities such as Bard, Marist, and the Culinary Institute of America. While students predominantly stay on campus, I have made day trips with my friends to all of these places, and have met some wonderful and interesting people doing so. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Logan: Vassar is a small school, totaling about 2,000-2,500 students. Because of this, and the fact that students primarily stayed on campus, there was a strong sense of community within the school. Most people there enjoyed this aspect of Vassar, however, I have heard some say that it creates a bit of a fishbowl feeling, where everyone knows everyone elses business. This does not fully describe my own experience, but there definitely is an element of that. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Logan: I once took a political science course taught by a very animated professor who would frequently make loud exclamations without warning. One day, after we began reading Friedrich Hayeks The Road to Serfdom, he made a comment about how peculiar it was that several Vassar alumni had gone on to become Republican politicians, despite the extremely liberal leanings of the faculty and student population there. The professor noted that one particular congressman, who he happened to have taught years earlier, was on television a few days prior lamenting the fact that conservative thinkers like Hayek were left out of most college curriculums. The professor then said, raising his decibel level every couple of words, So rememberif youre ever on TV, I TAUGHT HAYEK! I have had several much more mild-mannered professors, but that incident always stuck in my mind. Check out Logans tutoring profile.
