How to Use Chemistry to Boost Your Chemistry Vocabulary

How to Use Chemistry to Boost Your Chemistry VocabularyYour Chemistry vocabulary is an important part of the way you think and how you communicate with others. This is a science where you study and learn about chemical compounds that can make up our world. However, this does not mean that learning the vocabulary is only important to how you use chemistry to learn about these compounds.Most of the time, how you use chemistry is not just knowledge is not important; it is the way you think. This is what the Chemistry vocabulary means to you. The more knowledge you have about these compounds, the more comfortable you are in your interactions with others. You also know how you perceive the world around you as well.The words you use can either inspire you to think more or deter you from doing so. For example, if you do not know what a fluoride is, this could be the difference between you finding out about this compound and brushing your teeth every day or it could be the difference between having healthy teeth that are not healthy. A good way to combat this is to learn the proper usage of these words.Vocabulary is very important. If you think it is important, you will use it. However, your interactions with others might go differently if you did not know the proper vocabulary to use with them.Therefore, it is very important to brush up on your Chemistry vocabulary every now and then. There are many places you can go to learn about this subject. Of course, there are many books you can read as well, but what if you do not have the time to read these?Maybe you are working a job or you do not want to be tied down to a book all the time. What better way to stay connected with the world and learn about the subject than to take an online class? These classes are usually a fraction of the cost of a college class, and you can get more learning at your own pace.So, how much chemistry knowledge do you really need to understand how the world works? In a word: No. You should not try to over-inflate the value of the chemistry you need to study. It is one thing to know the basics of this, but there are other sciences that you should understand as well.Your Chemistry vocabulary is an essential part of understanding the world around you.

Organic Chemistry Tutors - How to Select the Right One

Organic Chemistry Tutors - How to Select the Right OneWhen choosing an organic chemistry tutor, it is important to consider many different aspects that go into the process. Finding an instructor who has a variety of topics that are interesting to the student is crucial to getting the most out of his or her experience. The two main factors in this choice is the knowledge that is provided by the instructor and the ability of the tutor to provide the right mentoring for the student.The first thing to consider when choosing an organic chemistry tutor is what will the tutor do to enhance the student's knowledge in this area? Some people believe that there is only one course that is needed for a successful career as a chemical engineer, whereas others would argue that there are numerous different levels of mastery that one can obtain. The decision to go with an instructor with more than one level of knowledge is the way to go if you are not sure about the specific career goals that you hav e in mind.Another aspect that can make or break an organic chemistry tutor is whether they will be able to offer support to the student during the course. If they give you a lot of assistance then you will not need to be frustrated. On the other hand, if you are being stonewalled, it can actually help to work on your own. It is really up to you to work hard and work smart, but you also need to find the right person to work with.Once you have narrowed down your choices, you need to ask the person yourself if he or she is a good person to work with. You need to find out how long he or she has been teaching, how many students he or she has had, and the specific topics that he or she focuses on.If you are looking for an organic chemistry tutor that is not just a newbie in the field, but someone who has taught before then the selection process becomes even more difficult. It is really up to you to ask as many questions as possible before you accept a teacher into your life. Most teachers like to answer questions honestly and at the same time offer constructive criticism.What you need to ask is why the person is a good teacher, because the next question is how he or she knows what it takes to be successful. The only way to figure out this is to ask the teacher for feedback, so you know what to expect and how to handle situations. Also be sure to ask for references if the teacher has a few good ones, because this will make it easier for you to choose someone who is great.These are just some of the questions that you need to ask before you hire an organic chemistry tutor. Make sure that you know all of the answers before you decide on hiring anyone.

As mentioned, the bachelors and masters programs covered under the umbrella term fine arts includes a lot of crossover from all three categories of art. These programs can range from theater and photography specializations to illustration and digital media.The differences in the types of art that will be included in this degree will vary from university to university. That being said, there are many common program s you will find in this field.

For example, a design program can be found both in universities with a focus on fashion as well as universities with general fine arts degrees.Film SchoolThat being said, film schools are an entirely different beast. While you may find film programs in a lot of different university programs, there is a copious amount of schools dedicated solely to developing the technical skills involved in film.This can mean that you can find lecture-based programs that specialize in components like film theory or universities in which you will be directing or filming movies the majority of the time. Some of the most common types of programs you will likely encounter in this kind of school are:Computer animationFilm and television productionPhotographyGame artArt HistoryAnother avenue to explore if you’re interested in learning more about your craft, or even if you don’t have any sort of artistic ability, would be to study art history.

Being close to the European Union, looking into more affordable schools in schools just a plane ride away can be a viable option. On the other hand, looking for scholarships within your college of art or government grants can also go a long way in relieving the cost burdens of your college tuition.That being said, here are the best universities in the UK to study architecture, art and design differentiated by the discipline they specialize in. The application requirements will also be different from school to school, so make sure to watch out for these distinctions.Film EducationArts University Bournemouth â€" this film program doesn’t just pride itself on being interdisciplinary, but it also has the record to show it.

What is it Like to Attend Portland State University

What is it Like to Attend Portland State University The tutors behind Varsity Tutors are not just here to teachtheyre sharing their college experiences as well. Austin is a Portland tutor specializing in English tutoring, French tutoring, public speaking tutoring, and a number of other areas. He is currently a senior at Portland State University majoring in arts and letters, French language and literature, history, and social sciences. See what he had to share about Portland State University: Describe the campus setting and transportation options. Austin: Portland State University is located in downtown Portland, Oregon. This central location in the city provides for a number of transportation options, including ample bicycle lanes, parking structures, and multiple lines of light rail. For this reason (and because of the diversity of student ages), few students live on campus. This means that the feel of the university is both omnipresent and absent from the citys heart. The boundaries of campus and city are not defined, and many students do not even live in the city of Portland itself. (This is my situation.) Portland is relatively safe (for a U.S. city), but that still leaves plenty of danger. The university has park blocks, or urban walkways with green space, which become unsafe during parts of the night. That being said, the daytime sees such heavy foot traffic that safety is not normally a problem. How available are the professors, academic advisers, and teaching assistants at Portland State University? Austin: There is little consistency in how available professors are. Academic advisers are available, but exactly how useful they are varies widely. Teaching assistants are not present in many classes, but they are often quite available. How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Austin: Like the majority of Portland State University students, I do not live in the dorms. It would be unfair to merely spread hearsay, but given that Portland State University does not have a normal percentage of students living on or near campus, the dorms do not play such a central role as at some other universities and colleges. Which majors/programs are best represented and supported at Portland State University? Austin: Developmental psychology, conflict resolution, business, and engineering get a good showing at Portland State University, among others. That being said, rankings and self-elected specialities are always debatable. I am currently striving for four majors (social sciences, history, arts and letters, and French language and literature). I may or may not also earn a minor or two, depending on the next term. I would argue that the university did an often mediocre job of supporting my areas of study. Without comparing it to other institutions, it is still possible to say that my goals were as much hindered as they were helped. 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? Austin: I was incredibly engaged in my high school and had many great friends. A year later, I found myself reduced to tears, wailing to my mother about my lack of friends and even basic social engagement at Portland State University. Greek life does not play an important part in this university and its social life (or lack thereof). My way into a now much more satisfying social life was through working with a study-abroad company based at Portland State University that hires a diverse range of American and international students to welcome and support short-term study abroad students from East Asia. How helpful is the Career Center and other student support services? Austin: My future career choices are in academia, and therefore I have not attended these sessions. Instead, I seek out professors and ask how they got where they are. How are the various study areas such as libraries, the student union, and dorm lounges at Portland State University? Austin: Portland State University does have spacious study areas, but it is also the largest university in the state of Oregon, and so things can get crowded. Describe the surrounding town at Portland State University. Austin: Portland is a very dynamic city that is becoming increasingly popular. As previously mentioned, there is little to no distinction between Portland State University and Portland itself, in many cases. Portland State University is a few minutes away from major theatres and shopping malls, and it is relatively close to great hiking, two hours from the coast, less than that from Mount Hood, etc. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Austin: Portland State University is the largest university in the state of Oregon, and it has many students in many classes. However, higher-level courses across departments may not be large even with a mix of Master and Bachelor students. Check out Austins tutoring profile.

What is a Stem and Leaf Plot

What is a Stem and Leaf Plot In a stem leaf plot of quantitative data, each value is divided into two portions- a stem and a leaf. Stem represented on a vertical axis whereas leaves of the corresponding stem will be represented on the horizontal axis. For an example 35, 39, 30 can be represented as 3 | 0 5 9 Where 3 is the stem and 0, 5 and 9 are the leaves. Example: - The following are the scores of 18 college students on a statistic test: 52 80 96 87 95 81 61 86 50 64 71 87 57 Construct a stem leaf plot. Solution: - To construct a stem leaf plot for these scores, we split each score into two parts. The first part contains the first digit, which is called stem. The second part contains the second digit, which is the leaf. Thus, for the score of the first student, which is 75, 7 is the stem and 5 is the leaf. We observe from the data the stem for all the scores 5, 6, 7, 8 and 9 because all scores lie in the range of 50 to 98. Now we will create the leaf for each of this stem. 5 | 0 2 7 6 | 1 4 7 | 1 8 | 0 1 6 7 9 | 5 6 Example: - Construct a stem leaf plot for the following data. 57 35 18 21 51 47 21 46 42 39 Solution: - 1 | 8 2 | 1 1 3 | 5 9 4 | 2 6 7 5 | 1 7

Planning a Yoga Retreat in India

Planning a Yoga Retreat in India How to Plan a Yoga Retreat in India ChaptersWhat to Expect Before You Go on a Yoga RetreatYoga: Living on an Ashram in IndiaPractising Yoga in an Ashram“Yoga is not a religion. It is a science, science of well-being, science of youthfulness, science of integrating body, mind, and soul.” - Amit RayA yoga session is a bit like a bubble of well-being. Be it breathing exercises, meditation, mindfulness, or alignment, daily yoga practice has become a ritual for a growing number of Britons and certain parts of India have become essential destinations for those wanting to do yoga effectively.In the UK, there are between 300,000 and 460,000 people regularly practising yoga. Of the 300 million yogis on the planet, more and more people in the UK are joining them to find moments of relaxation. This is why many people are also opting to attend yoga retreats in India, the home of yogic culture. India may seem far away and scary, especially when it comes to trying to organise a yoga retreat out there.Let’s have a quick look at what to expect in an Indian ashram and how you can enjoy yoga sessions on a retreat.

(Source: Free-Photos)Heading to India to enjoy a retreat on an ashram is a good idea but you can’t just wing it. You’ll be heading off to a country that’s vastly different to the UK. There are different traditions, food, and everyday life to enjoy.The customs are different but so are the ways of going about things so get ready for an adventure! For example, don’t forget your visa, which can buy for around £20.Once you’re there, you’ll realise that each ashram is unique and you’ll need to do your research before you can head to the right one. After all, you’re looking for somewhere to find inner peace and somewhere to stay.  Unlike “yoga centres”, which don’t offer accommodation, ashrams include somewhere to stay day and night. If you stay for a few days or weeks (or even more), you’ll soon be a yoga master.Just like heading anywhere else in the world , there’s an ideal time of year to travel to India and learn to let go through yoga. The high season is in January and February whilst from May to September the weather is anything but mild. The rainy season is also a great time to enjoy quieter ashrams.  Similarly, October is the best time to head to India, especially when it comes to doing yoga. You’ll get more time with the instructors and a more relaxed environment.You should know that the ashram won’t cover the cost of the flights but they often provide a shuttle from the airport.Yoga: Living on an Ashram in IndiaYou may feel a bit overwhelmed when you first set foot in an ashram. Even if you’re prepared for your time there, you might still feel a bit stressed. You might be wondering how you should behave in front of the others. In reality, you’re not obliged to do anything. After all, those visiting ashrams are there to learn more about yoga. Being on an ashram isn't the same as attending a yoga class. (Source: jeviniya)Firstly, you don’t have to be passionate about yoga to head to an Indian yoga centre. The idea is to get into the practice, but you don’t need to be a yoga professional. Attendees are often young and inexperienced.Some ashrams even offer trips around the region or the chance to do charity work for the organisation. Generally, there are different options and packages available and it’s more than just a few yoga poses or a detox.However, while we’re talking about detoxes, let’s talk about new technologies. In most Indian ashrams, you can use your mobile phone, but it’s not recommended that you overdo it. After all, yoga is about finding your centre, not distractions.In terms of history, ashrams have existed for thousands of years and were generally isolated places away from distractions. The sages would spend time alone without any type of distraction or means of communication.This is an opportun ity to realign your mind, body, and spirit. This inward reflection encourages us to sympathise with others. Even though there may be other people from the UK, they’ll all be there to benefit from yoga on a personal level.It should be noted that meals are eaten in silence in most ashrams in an attempt to practise mindfulness.In most ashrams, English is widely spoken since it’s a common language amongst yogis around the world. The universal nature of yoga means it’s for sharing.You’ll eat ayurvedic vegetarian food. The water is often filtered for Western visitors.So what is the yoga on an ashram like?Practising Yoga in an AshramIt’s difficult to talk about a yoga retreat in an Indian ashram since each of them is so different. However, there are two main aspects of it: yoga and meditation. After all, that’s what you’re probably expecting. While yoga is practised all over the world, it's still very much an Indian creation. (Source: lograstudio)Meditation is the art of finding yourself, making the most of silence, harmonising with your body and mind, and rediscovering the connection with yourself. The instructors are there to help us do this in the best way possible.  The yoga practised can vary from ashram to ashram: Hatha yoga, Kundalini yoga, Vinyasa yoga, Yoga Nidra, etc. Do your research before you book your trip.There are yoga classes for everyone, regardless of their level. No matter your age, everyone is welcome and can do the lessons at their pace.You’ll want the most comfortable clothes possible while also adapting to the local traditions and styles. For example, nudity is not tolerated and neither is tight clothing.Don’t panic if you’ve only brought tight sports clothes, there are plenty of shops in town where you can get more suitable clothing. Some ashrams even have shops.Nowadays, yoga retreats are b ig business and are popping up everywhere. Of course, this means it’s harder to choose the right one, but in most ashrams, the yogic tradition is still at the heart of everything they do. Practising yoga in India will be an unforgettable experience. (Source: jpeter2)So what type of ashram will you look to visit? Ready to reconnect? If you're interested in teaching a yoga class when you return, you might want to join the many yoga teachers who've done their yoga teacher training in the home of yoga. Whether you want to focus on Ashtanga Yoga, Vinyasa Flow Yoga, Iyengar Yoga, Prenatal Yoga, or even yoga for beginners, there's a thriving community of yoga instructors who've learnt how to share the restorative yoga practice in its homeland.If you're looking for something a little closer to home, however, you can always find a yoga instructor in your local yoga studio or look for online yoga instructors on Superprof, for example. It's never been easier to learn yoga poses, breathing techniques, and enjoy guided meditation.If you'd like to get started with yoga, try the talented tutors on Superprof. There are plenty of tutors offering plenty of different types of yoga. Simi larly, there are three main types of yoga tutorial available, too: face-to-face tutorials, online tutorials, and group tutorials. Each type of yoga, tutor, and tutorial has its pros and cons so you need to think carefully before you pick your tutor.Face-to-face tutorials are between you and your tutor, allowing you to benefit fully from the tutor's expertise every second you're with them. They'll put together sessions and courses that are tailored to you. Of course, this bespoke service tends to come at a cost but since it's all done with you in mind, it makes this type of tutorial the most cost-effective you can get. If you've got the budget for them, these are the ones to go for.Online tutorials are also between just you and the tutor but your tutor won't be there in the room with you. Thanks to the internet, anyone with a decent webcam, microphone, and internet connection can get tutoring from anyone, anywhere. With fewer expenditures for travelling and the ability to schedule mo re tutorials each week, online tutors tend to charge less per hour than face-to-face tutorials. You may even get a tutor from India!Finally, group tutorials are available for those that are happy to share their tutor's time with others. Whether you and a group of friends opt to practise yoga together or you start attending tutorials with a group of strangers, these tutorials tend to cost less per person per hour since the whole group is paying for the tutor's time and expertise.
