Definition of Error in Chemistry

Definition of Error in ChemistryIn this article I will try to help you define error in chemistry. Error in chemistry is defined as a scientific matter that is invalid, as well as a scientific situation that is invalid. Such definitions are quite useful for me, because I work with science all the time and I have been successful with them.The thing is, I need to define an error in chemistry first, because I have already talked about it a few times. I have stated that, in chemistry we use the rules and the formula to define what is correct or incorrect. This is important for the practice of science, and to some extent, to the understanding of how science works. But if you consider another perspective, and the relationship between mathematical models and scientific theory, then you will see that, in both cases, the rules and the formulas are rather useless, and sometimes, actually detrimental.For example, take the term 'harmonic'. In the so-called elementary school, we used this term to describe that a particular piece of music is full of harmonic structure, so that the musical part is harmonically complete.We do not know how to define harmonic problems, and they are not part of current mathematics. As an alternative, let us talk about what 'harmonic is' and why it is such a big problem.If we compare current mathematics with the technique of music, we see that, the mathematical part has a kind of harmonic structure. There are many different scales, which give rise to different harmonic structures. And this is not something that we can derive from a logical concept, such as prime number.The fact is, in recent years, music has gained a lot of popularity, and its complexity is regarded as a challenge to the mathematical model. When we talk about such a scale, it is useful to use simple terms and represent it by a single note, but what actually happens in nature, is that, we get scales that lead to many notes, each one different from all the others.The same thing has h appened with the development of the math scale, and this was also in recent years. And it is now, in the 21st century, when this has become a hindrance to science, because it tends to confuse the reality with a mathematical model.

Why Now is a Great time to Prep for the SAT in the Fall

Why Now is a Great time to Prep for the SAT in the Fall Taking the SAT in the Fall: Why Now is a Great time to Prep Most students choose to take the SAT in the fall so they can start planning for college applications and have the opportunity to take the test a second time in the spring if need be. Unfortunately, fall is a busy time of year for high school students because they are not only adjusting back from summer break but are also focusing on starting new AP classes and writing personal statements for college applications. Students who prep for their SAT over the summer find that its easier to focus on this one important task when there are fewer distractions and obligations to get in the way our private Irvine SAT tutors are here to help you prep over the summer. 1. Work with a one-on-one private tutor Summer is a great time to work on improving your SAT score with a one-on-one private tutor who can come to the home and help college-bound students create an individualized plan for success. Without the distraction of other academic obligations, students can focus 100% on SAT prep and achieve their best possible score. During the school year, students are limited to working with a tutor after school hours and find that theyre already mentally drained from the school day. During the summer, however, students can work with their tutor any time of day and for the amount of time that suits the student’s academic plan. 2. Increase your score Many students take a practice SAT only to find out they want to increase their score by a large number of points. Its getting harder and harder to get into university these days and so students who reach their highest potential score are more likely to be accepted to the university of their choice. When students complete SAT prep for the summer, they have a much better chance of increasing their score and expanding their post-secondary opportunities. 3. Reach college goals Most students have ‘safety, ‘target, and ‘reach’ schools. Safety schools are ones that students feel they can get into no matter what based on their current grades and SAT scores. Target schools are schools which students have a good chance of getting into and probably fit the average profile of an admitted student while reach schools are ones that are difficult for anyone to get into and would be the student’s ultimate dream college. When students focus on their SATs over the summer, they have a better chance of determining what will help them get a higher overall score and ultimately reach their college dreams (READ: 4 Great Ways to Study for the SAT this Fall). 4. Maintain a balance Its also important for students to be able to maintain a healthy work-life balance throughout the academic year. When students try to focus on college applications, AP classes, a part-time job, and SAT prep their free time dwindles down to nothing. However, the summer months offer a great opportunity to focus on just one fundamental academic goal while still having time for family, friends, or a summer job. 5. Leave time to focus on classroom assignments When students wait to focus on their SAT prep during the school year, their grades in their classes can start to slip. They might become overwhelmed or just not have enough time to finish everything they need to get done. When students finish their SAT prep over the summer, they have the opportunity to focus 100% on important classroom assignments and make sure theyre getting excellent grades in their honors or AP courses.

A Spoonful of Support Helps the Medicine Go Down

A Spoonful of Support Helps the Medicine Go Down http://memegenerator.net/instance/43366087 But there was one episode in particular that has stuck in my head since and it was this whole discussion about medicine. How people in this day and age use pills to numb their aching backs, heal their headaches, relieve their stomach pain or even mend their broken hearts. This guest speaker kept talking about how we are so incredibly dependent on medicine that we no longer know what real emotion, real pain and real human struggle feels like. We use these tablets as crutches and sooner or later it becomes us. And I remember sitting there as a young healthy nine year old girl agreeing with every word they said. http://www.salon.com/2010/04/28/interview_whitaker_anatomy_of_an_epidemic/ Then as an eighteen year old, I decided it was time to talk about medicine and the  good  that it does to society. When I talk about the good of medicine, I am not referring to people with addictions that absolutely need heroin or cocaine in order to function. There is a difference between drugs and medicine. I believe we are actually a society that fears taking medicine. For some reason, having a prescription for anything but the common cold makes us feel like we are doing ourselves a disservice. For some odd reason, we are suddenly not normal. We push ourselves and for others to not take medicine, because having to swallow something that sits in an orange pill bottle from Walgreens pharmacy makes us feel defeated. http://www.lovethispic.com/image/34263/im-losing-my-mind-and-no-one-cares To say to others, Yes, I need to take Xanax every single day in order to feel okay suddenly equates itself with I am a failure of a human being and I cannot count on myself  to be okay. Im saying this because I have said it. Having depression in the fourth grade and then being re-diagnosed with depression and anxiety disorder my freshman year has led me to believe the latter statement. I have cried many nights telling myself that I can do without medicine. I have heard people tell me that they wish they didnt have to see me take my prescriptions. I have been pressured by my parents to not take medication because their excuse is its bad to take medicine. And youre so young, you shouldnt have to take it. I have cried to my therapist and told her that I didnt want whatever she prescribed to me. I have seen doctors look at me funny when I tell them what I have to take for my medical history. I believed that I would be normal  if I didnt take medication. http://www.boldlybe.com/category/accountability/ I have experienced internal conflict where I feel as if I am less capable or less brave since I need to be on something in order to not cry, panic or feel hopeless; I try to not take anything because I would rather fake being normal and believe that I am stronger and I am able to do without what I have been prescribed. There should never  be stigma about taking medicine. As long as you are not misusing it and becoming physically/mentally dependent on it and you are instead using it to forward yourself and to make your life better and more controllable, then you are doing nothing wrong. If what you are taking is giving you the ability to  feel  normal, then for the love of God, please take it. Is it nice to be able to say that you dont need to take pills to be okay? Yes, of course it is. But as long as human beings exist, problems will surface and as long as we are alive, we will have to suffer through pain. And sometimes despite all the things that we use to make life a little easier, we need to take what is necessary to get through that one day or that year or that decade. I am not saying at all that we should convert to shoving pills down our throats constantly; I am saying that with proper use, no one should be shamed or feel guilt for having to do so. How can we expect people to get better if we are slamming down the very thing that can aid them to become better? A good attitude and healthy lifestlye goes along with taking medication. Taking pills can only do so much, but if we allow ourselves to accept it instead of marking it with disgust and disappointment, then we will be taking the first step to understand what good medicine can do. http://thisisnotajoke.tumblr.com/ Are you weak for having to take pills? No. Am I normal? Yes.   Life by no means is perfect and neither is the human body. We do what we can, but at the end of the day sometimes things dont work out the way we want them to. And you know what?               Thats okay.   http://www.mattvaillette.com/blog/2013/9/25/why-be-purpose-driven-artist So I guess in the end, we learned that Oprah isnt always right.

Here is a summary of how theatre and drama has changed through the ages  from Antiquity through to contempo rary drama.Earliest Classical Greek InfluencesThe term 'drama' comes from an ancient Greek  verb meaning 'to do' or 'to act', and this is when it all began for the tradition. Come to think of it, the literal meaning of this word is very apt in describing the activity, yet the word has evolved over time to offer different meanings since its beginning. For example, in today's world, the word 'drama' is normally associated with situations that involve a conflict of emotions.There were originally thought to be two types of drama: comedy and tragedy. That said, when you refer to dramas from  the 19th century, this term actually refers to a staged theatrical performance that is neither one nor the other (thus the term took on a new meaning of its own).A great example of a play or drama from that period is Ibsen's A Doll's House, which has subsequently been directed and performed by many theatre groups and studied as part of literature courses in secondary school and at university.Yet anot her genre of drama produced by ancient Greece was a satire, or  satyr playAncient Greek theater would have been very dramatic (almost like a pantomime), consisting of a Greek chorus, costumes, theatrical masks, and other ritual characteristics all of which would have been staged in an open air setting.If you hear anything along the lines of Agamemnon, Antigone, Agon, Apollo, Aristotle, Athenian, Attica, Bacchae, Epidaurus, Eumenides, Dionysus, Oedipus The King, Prometheus Bound, Parados, Perseus, Dithyrambic, Iphigenia, Seven Against Thebes, Lysistrata, Orestes, Peloponnesian, Parados, Plato, Socrates, Cyclops, Plautus, Thespis, Zeus, the list really does go on and on! And all have their own links to ancient world plays by way of mythology, Greek gods, Greek empire, a representation of religion or Greek society and culture. Greek theatre would have painted a picture of the legendary Greek empire.The most significant playwrights of Greek tragedies  are Aeschylus, Sophocles, Euripides , Aristophanes and Menander.The first three dramatists are commonly referred to as tragedians, whilst the two latter lyricists were seen as comic writers. If you have read a Greek tragedy as part of one of your educational courses or because you are drawn to the suspense, you will be familiar with the chorus, or group of people, who commentate on the story as it unfolds.Discover different online acting classes on Superprof.Roman InfluencesRome was introduced to Greek drama and Greek comedy around 250 BCE, and many Romans reworked the original plays, dividing the stories into episodes, removing the choruses and replacing them with a musical element like an orchestra, or having them singing.The Roman times were still influenced by Greek gods and mythological Greek culture, but Roman theatre was equally expressive of themes significant to Rome, Sicily and society in Italy in general, as well as classical literature and religious rites. Performances would have been composed of Venetian masks, ceremonial dancing and stylized with a range of facial expressions.Medieval And Renaissance DramaHundreds of years after the first ever creations of tragedy and comedy, Medieval Drama brought something totally new to theatre, in a move away from reworking older styles. With the Christian Church originally opposing theatre, seeing it as controversial, religious holiday stories and scenarios from the Bible naturally started to be performed by leaders of the churches, and eventually, these performances became more elaborate and moved to other parts of the community (i.e. the stage).The Christian church originally opposed theatre. Photo credit: santiagolopezpastor on VisualHuntElizabethan drama developed during the Renaissance period thanks to a rejuvenated  celebration of all types of art. The first ever Elizabethan playhouse opened  around this time and plays by famous playwrights (like the acclaimed William  Shakespeare, of course) were performed regularly across the country. His plays were more structural than had ever been seen before, and represented comedy tragedy combined  to give well-rounded performances offering something for everyone.18th And 19th Century DramaClasses were very much divided in the 18th century, and writers drew on this in their texts. Many plays were therefore written for and about the middle class, moving away from the outdated themes that were covered by Shakespeare and his peers. Plays played on the  battle of the sexes and were witty and humorous.In the 19th century, Romanticism in Western Europe was born and focused on emotion and spiritualism,  heavily influencing drama of the period. Romantic plays began to dominate the continent, with famous writers like Faust and Johann Wolfgang von Goethe becoming hugely popular.Modern DramaModern drama is what we would call many of the plays that emerged from the 20th century onwards, which developed due to further experimentation. Music played a big part in modern drama, while realis tic drama was also increasingly popular. For some, though, this seemed a step too far from the origins of drama and theatre and they wanted the art to be revitalised once more.Symbolist drama became a preferred style of performing, particularly in France. Photo credit: Torekhan Sarmanov on VisualHuntThis made way for a Symbolist movement, particularly in France, in the 1880s.Texts became suggestive and almost dream-like. Chekhov and Ibsen are good examples of masters of strong Symbolist drama.The Expressionist movement came about in the early 1900s and was darker and more grotesque, exploring the depths of the human psyche, turning stage shows into more like  nightmares!Other forms of theatre - pioneered for example by Bertold Brecht in Germany - sought to disassociate viewers from the emotions of the characters so that they could focus on the theme of the play.Finally, contemporary playwrights of the 1960s and 70s began to focus more heavily on language and dialogue, with Tom Stopp ard for one being a very important writer of the time.This brings us to the 21st century, and theatre as we know it today.There are numerous 21st century dramatists and playwrights actively writing today, yet many stage actors are still representing characters from classical plays, at times with a modern twist. Musical theatre is also a very prominent scene.In a world that is obsessed with fantasy, many of the dramas that are turned into TV adaptations are linked to escapism yet we are all just as interested in the realism of other people's lives, hence why reality television is so popular in modern society.The variety of different types of drama in modern times means that there is also a lot of room for different styles of acting.For those interested in reading up on theatre history, or reading some of the Greek literature plays that derived from the classical Greek period or thereafter and the heroes that write them, you can find the most famous titles and plots (including a famil iar tale or two) as well as biographies and history books by visiting academic book shops like Oxford University Press or Cambridge University Press.But it's not just Cambridge and Oxford that are in the know about these ancient poets, philosophers and playwrights, bookshops across the country will have sections dedicated to ancient Greek plays through to modern day literature.Drama On The CurriculumIn the UK, children up to the age of five are taught using methods that involve play, thus Drama is taught within the English curriculum at this early stage and through to Key Stage 4 as part of Speaking and Listening elements. The Spoken language section of the curriculum states that:All pupils should be enabled to participate in and gain knowledge, skills and understanding associated with the artistic practice of drama. Pupils should be able to adopt, create and sustain a range of roles, responding appropriately to others in role. They should have opportunities to improvise, devise and script drama for one another and a range of audiences, as well as to rehearse, refine, share and respond thoughtfully to drama and theatre performances.Schools are lacking in Drama facilities because of low numbers for the creative arts. Photo credit: madame.furie on VisualHunt.comThis means, therefore, that Drama is part of the statutory National Curriculum, yet many in the industry feel that this art should have more weight and be taught as a mandatory subject through to Year 11.The above makes it clear that Drama plays a key role in learning, and that children should be enabled to express themselves through theatre and performance. With no Drama facilities and otherwise use-able budgets being spent in other areas of schools, this means that centres which don't offer Drama (and even some of those who) aren't giving their pupils the opportunities they require and are promised by the Department of Education to learn through role-play, understanding how to put together performances on a stage and standing up in front of an audience.Many secondary schools do also offer Drama as a discrete subject from Year 7 and then as a subject choice at GCSE, but with numbers dropping for the arts, many have removed the option altogether.This, teamed with top universities discouraging pupils from taking what they call 'soft' subjects, has resulted in many pupils avoiding Drama or simply missing out on the benefits of the subject through no choice of their own.The DfE seems set on creating a 'one size fits all' curriculum whereby the arts have no place and are being forced out of schools. If they are not careful, all creativity will be taken away from students and their overall experience of education will become less stimulating and fulfilling (since Drama has many additional cross-curriculum benefits too).Furthermore, as a result of the decline in uptake of subjects like Drama, teacher training centres for the subject matter are getting harder to come by.Are you a Drama tea cher struggling to find a position in a school? Like many others, you are probably urging decision-makers in schools to buck up their ideas about the creative arts, not only to help you find work but also to prevent all of those generations of pupils being denied an opportunity to learn about Drama.Begin acting classes today with a private tutor from Superprof.
