What Is Spectroscopy Definition Chemistry?

What Is Spectroscopy Definition Chemistry?Spectroscopy Definition Chemistry is a scientific discipline that deals with the study of the properties and behavior of matter on the atomic level. Chemical spectroscopy and photomicroscopy are related methods of determining chemical properties of an object, sample or living tissue.The light used to determine chemical form should have the right characteristics to be absorbed by the molecules. Most light sources produce electromagnetic radiation, which can be divided into visible light and the ultraviolet (UV) light. Spectroscopy Definition Chemistry is an attempt to measure the spectrum of light waves to predict the chemical properties of molecules.Light and wavelength describe the characteristic wavelengths that we observe when an object is viewed by the human eye. We can measure the wavelength of the light by scanning the object. We can also measure the intensity of the light, which is the total amount of energy contained in the light. The intensity can be expressed as the energy divided by the square of the wavelength.All wavelengths that can be observed by the human eye have one characteristic wavelength. The spectra of light that we see is a series of circles made up of equal and opposite shaped segments. The whole series of circles has a common diameter and they all begin at one wavelength and then increase in length until they reach the next wavelength. So, we see a continuous series of very long thin lines.So, the circle represents all the light that was not absorbed, reflecting off of the object and being reflected back to us. So, you will see a series of circles made up of equal and opposite shaped segments. There is nothing in the circle but lines of energy; all the energy is contained in the lines of light and this means that each segment of the circle is made up of straight lines that cross each other.As each line crosses another line it will become more intense in color. The intensity of each line of the circles increases until it passes through a boundary, which is the light source. The lines from the light source can then be used to 'see' what color the light was at the time that it passed through the light source. This method of spectroscopy can be used to detect the chemical makeup of a substance, sample or living tissue.By using a spectrograph, we can determine what the compounds in a substance, sample or living tissue are made up of. It can also be used to determine how much the substance contains of a specific compound. This method can be used to determine the effectiveness of drugs, their safety for a human being or for a laboratory test.

All About The American Revolution

All About The American Revolution What Brought On the American Revolution? ChaptersPrelude to the American RevolutionThe Fight for American IndependenceWhat Was the American Revolution and Why was Tea Involved?Thoughts on the American RevolutionAs our prime ministers are fond of saying, the UK has long enjoyed a special relationship with the United States - quite possibly because the first settlers in that land that would become the U.S. were British citizens!Indigenous peoples’ claim to the land and settlers’ origins notwithstanding, the American Revolution is a fascinating slice of political and economic history that gave rise to world power; one who still today is a leader in global affairs.For better or worse...  Did you know that the Great Depression started in America?We now go back in time, to uncharted territory that could only be reached by ship, to discover the reasons those isolated colonists rejected kingly rule and established themselves as citizens of an independent, yet-to-be-established nation.Rump Parliament in 1651, that was meant to r egulate trade in The Colonies, records show that colonists were not severely impacted by it.However, it sowed the seeds of discontent and anger towards The Crown; sentiments that were passed down from father to son, through the years, with each insult adding fresh fuel to the simmering fire.The idea that England and the monarchy should more greatly benefit from the Colonies’ trade and labour than the colonials themselves was the root of their ire.King Charles II did not help matters when, in the 1680s, he revoked their colonial charter. And then, King James II established dominion over New England â€" as that region is still known today.Politically, that meant that not only did the colonists lose their right to an autonomous government but they became subject to England’s laws once again, including the economically punishing Navigation Act.James II abdicated/was overthrown in 1688. The colonists celebrated their mother country’s change of government with an uprising that cast off dominion rule; the colonies were once again governing themselves.Subsequent English governments did not attempt to impose leadership on the colonists; instead, they treated them as trading cash cows, fervently taxing them on everything they exported, from wool to hats.The Molasses Act (1733) was particularly incendiary because the colonies derived much profit from the sticky, sweet substance.Rather than paying the heavy duties that the law attached to them, the colonists resorted to bribing or intimidating British customs officials working American ports in order to ship their products to other nations.Here, we see the mindset of those engaged in such trade.As those merchants tended to be more politically aware, their circumventing English laws shows their readiness to establish themselves as a trading entity in their own right.By the 1760s, they were ready to fight for total independence from England.The colonial militia would confront British soldiers in full uniform Source: W ikipediaThe Fight for American IndependenceIn quick succession, a flurry of taxation laws was passed in English parliament:The Currency Act was meant to restrict the use of paper money (1764)The Sugar Act imposed duties on a number of items, including sugar (1764)The Stamp Act: anything made of paper, from pamphlets to playing cards, was required to have a stampThe colonists did not mind those taxes as much as they resented being taxed in absentia.With no one in Parliament to represent them, those edicts were seen as unilateral and imposing, especially as the colonies were getting no support from England and, in fact, were made to fight wars â€" for them on foreign soil and against them on their home turf.Of all of the insults, this taxation without representation was the straw that broke the camel’s back.The Sons of Liberty, a rebel group, went on the offensive. They demonstrated â€" not always peaceably, set fire to public records and looted Chief Justice Thomas Hutchinson’s h ome.Other colonists, taking a more diplomatic (and less destructive) tack, presented the Declaration of Rights and Grievances at the Stamp Act Congress in New York.It is important to note that, even at this time, colonialists considered themselves Englishmen, with all of the rights and privileges due them under English law.You can imagine how those with such a loyalist attitude felt when Parliament expressed the idea that the colonies belong to the Crown and thus were completely subordinate to Parliament rule.Besides, Parliament contended they were virtually represented, just like every other Crown subject.It might be seen as a concession to the colonies that the Stamp Act was repealed in 1766 â€" albeit because of heavy discourse from Benjamin Franklin.But, if it appeared that Britain was softening its stance, the Declaratory Act (1766) dispelled that illusion: they were keeping for themselves full rights to make laws and dispositions with regards to the colonies.Nevertheless, that small concession was a cause for celebration, for loyalists and anarchists alike.What Was the American Revolution and Why was Tea Involved?Shortly after the Declaratory Act, the British Parliament passed the Townshend Acts (1767) under the false belief that colonists’ grievance was having to pay internal taxes, not customs duties.Under these new laws, practically everything used in colonists’ daily lives, from tea to the glass to drink it from â€" anything imported into the colonies would be taxed.Americans protested these new taxes because they were not meant to regulate the colonies’ trade with other nations but to generate revenue for England.They had a valid point: already they had helped finance and fight wars, and they were paying heavy taxes as it was: how were they to thrive economically if constantly put upon â€" unlike other British subjects living in England?The crux of the matter was really about tea.The British East India Tea Company was the Empire’s largest co mpany but it was in danger of failing because tea smuggled into America from the Netherlands was much cheaper, undercutting their profits.The five Townshend acts were meant to ensure that anything destined for the American colonies had to go to England first, whereupon the English could sell goods at a huge markup and tax shipments heavily â€" and that included tea.The Commissioners of Customs Act, the fourth of the five Townshends, installed British customs officers in Boston and other ports so that smuggling â€" of tea and other goods became much more difficult.Once those worthies were installed, it became much easier to enforce the Indemnity Act, number three of the five Townshends, which voided tea taxes and sold British tea at cost â€" cheaper than smuggled Dutch tea.That was seen by the colonists as paltry coercion to force acceptance of the stiffer tariffs on other goods and they didn’t like that one bit!Now the pressure, on both sides, was really on...  just as, centuries later, Europe felt the pressure of Nazi Germany!A boat belonging to John Hancock ( the initial signer of the Declaration of Independence) was seized in Boston harbor under suspicion of being loaded with illegal tea from Holland.A large-scale riot broke out. British customs officials, fearing for their lives, fled the scene. To quell the riots and restore order, the British government sent troops to Boston.Boston Harbour, where once a shipload of tea was dumped Source: Pixabay Credit USA-ReisebloggerBoston, Massachusetts March 5th, 1770A large group of colonialists clusters around the British soldiers patrolling the harbour. They are angry, throwing snowball and debris â€" chunks of wood and glass. One British soldier takes a hit and, even though no order was given, they all open fire.Eleven civilians took a bullet; five of them died as a result.This event came to be known as the Boston Massacre and did much to turn any remaining British loyalists into American patriots.The soldiers were tried for their actions and acquitted in a British court. As a result, any chance at cordial relations between Massachusetts and London evaporated.While radical patriots such as Samuel Adams continued to incite anger against Britain, he also implemented and coordinated the Committees for Correspondence in all 13 colonies; a legitimate and respectable way to set up a government to rebel against British rule.That is downright bureaucratic compared to rebel patriot John Brown, who set fire to a British warship!Another bureaucrat, Benjamin Franklin, at the time Postmaster of the colonies, intercepted letters that were construed as proof of England’s intent to systematically suppress American rights.When confronted with this seemingly treasonous act by the British, Franklin admitted to taking the letters. He was then dismissed from his position.During this time, there were several acts of treason committed but, after John Brown’s burning of the Gaspee, no attempts were made to p unish traitors to the Crown.Meanwhile, the issue of tea was coming to a head.Boston merchants were appointed to sell British tea exclusively but they were soon forced to close shop under pressure from other tea vendors and the governor of Massachusetts himself.Furthermore, the governor declared that any incoming British tea ships would be turned back... but not before rascally rebel Sam Adams and his cronies, dressed in Native American garb, offloaded an entire shipment of tea into the harbour.This event became known as the Boston Tea Party; one of the world's most significant historical events.Thoughts on the American RevolutionAs British control of the colonies eroded, other intolerable acts followed. Indeed, they are now known as the Intolerable Acts:The Massachusetts Government Act restricted town meetings and changed its charterThe Administration of Justice Act called for British soldiers accused of wrongdoing to be tried in Britain instead of the coloniesThe Boston Port Act cl osed the harbour until England had been fully compensated for the tea tossed in the waterThe Quartering Act of 1774 required British soldiers to be housed in American citizens’ residences (with no compensation paid to the citizens).It is said that the tighter one holds on to something, the faster it will slip away.That certainly proved true in the case of the American Revolution: the more restrictive England’s laws became, the more reluctant, and then rebellious the Americans became - much as militant Austrians became after their country's annexation prior to the Second World War.Matters having come to a head in 1775, the colonists turned militant.When the British garrison received orders to disarm all rebels, said rebels fought back, earning a decisive victory in the Battle of Lexington and Concord.The first shot fired in that battle, the opening salvo of the American Revolutionary war that launched a brand new nation, came to be known as the shot heard ‘round the world.So di d the shot that launched the first World War!Incidentally, the special relationship phrase was coined by Winston Churchill in 1946, alluding to his American-born mother â€" not necessarily to any economic or political ties.

Future In The Past

Future In The Past Have you heard of future past? In todays class, your dreams are going to come true. We are going to time travel! Can you think of a time last year, and think of where you thought you would be right now? Youve just time travelled, and hopefully you thought of a sentence in the future past. Confused? Dont worry, this blog  post  will show you how to  use the  future past.We use  future in the past  to talk about something in the past that you  thought  would happen in the future (it doesnt matter if it actually happened or not). Take a  look at the diagram below:As you can see, both of the Xs are in the past, but the blue X is slightly closer to the present (now). This is because we thought the blue X would happen in the future. So how do we make a sentence to show we thought something would happen in the future?  There are two ways:Forming Future Past  1. would  + (base verb)example: I thought you would help him.meaning: I thought you  would help him (with his homework), maybe you did help him/maybe you didnt help him.example: He promised he would send a postcard from Hawaii.meaning:  He said (or he promised) that he would send a postcard to me from Hawaii, maybe he did/didnt.2. was/were  + going to + (base verb)example:  I knew you were going to the concert.meaning:  I thought that you were going to go to the concert and you DID go. (When you  use knew it is to show you were correct with your prediction).example: I thought he was going to crash the car, he was driving so fast!meaning:  He was driving dangerously, I thought he was going to crash the car, but he didnt.We use both of these forms in slightly different ways. Would + (base verb) is mostly used to show a voluntary action,  promise  or to make a  prediction:Voluntary action:  I knew Eric  would make  dinner tonight.Promise:  She promised that she would come to my party.Prediction:  I thought it  would be a disaster.When we use was/were + going to + (base verb),  we  are talking about a  plan  or a  pre diction:Plan:  David said that he  was going to bring  his camera with him, but he forgot.Prediction:  I had a feeling that it  was going to be  a disaster.Future Past Listening ExerciseNow that we have studied how to make  future in the past  sentences, lets practice  using them. First, take a  look at this video:As you can see, these are predictions in the past that people thought would happen in the future. I particularly like the  crazy robot that people thought would exist in 1960!Now its your turn to complete some sentences. At the beginning of the sentence, I have written  either  volunteer, promise, plan  or  prediction. That indicates what type  of sentence to write (would + verb or  was/were + going to + verb).Example: (prediction)  I thought that there _would be  _ cars before the 1930s.(promise) They promised I would ______________ before 1960.(prediction) They thought  there ________________ helicopter trains in 1940.(plan) He told you there _________________ lots of c ars in 2000.Great work! You may have noticed in these sentences that I placed time expressions at the end of the sentence. This is because in all future forms, time expressions cannot be at the beginning of the sentence. You must use the  past  simple  if you have a time expression at the beginning of the sentence- look below:As soon as I would  arrive  at the restaurant, I would order  a pizza.  IncorrectAs soon as I  arrived  at the restaurant, I would order pizza.  Correct (past simple)Future Past Gap Fill ExerciseYoure doing great! We just have one exercise left.  Identify if there is a  time expression, and then use either the  past simple or the Future in the Past  (would +verb or was/were going to +verb)  to complete the sentence with the verb in the parenthesis ( ). As always, write your answers in the comment section and we will give you some feedback!(Husband and wife talking on the phone. Husband at football match, wife at home) Before you _____________ (go) to the footba ll match, I _________________ (make) you some lunch.2. They promised that they ______________  (come) to my birthday party, but no one came!3.

Brasil é notícia pelo mundo, aprenda Inglês com isso!

Brasil é notícia pelo mundo, aprenda Inglês com isso! Em um outro artigo, comentei que costumo ler notícias em Inglês,muitas vezes sobre o Brasil, como forma de melhorar o meu conhecimento da língua e enriquecer o meu vocabulário. Desde o anúncio de que iremos sediar a Copa e as Olimpíadas tem havido muito mais material disponível, inclusive de pessoas que tentam convencer possíveis visitantes de desistirem de vir ao Brasil como na imagem ao lado. Agora, desde que as manifestações começaram, o volume de notícias sobre o Brasil é ainda maior, fazendo com que exista uma oportunidade de melhorar a compreensão escrita e oral do idioma ao mesmo tempo que nos mantemos informados sobre o que passa na imprensa internacional.No entanto, ler notícias e mais notícias, todas elas dizendo mais ou menos o mesmo pode ser frustrante. Se você quer variar um pouco e sair do formato de notícia padrão, saiba que existe uma grande variedade de material circulando, muito do qual é produzido por brasileiros. Desconheço a autoria da image m que ilustra este texto e embora a mensagem não seja completamente honesta, é possível aprender alguma coisa através dos erros. Uma hipótese de dizer o que está escrito corretamente seria: Dont go to Brazil, there crime is free and has full government support. People under 16 years of age have a free pass for all types of crime. There are cruel killings and cases of rape in public transports, but there are no laws for these crimes.Enquanto algumas das coisas que são produzidas têm péssima qualidade, servindo apenas para que você aprenda com os erros. Outras contam com um Inglês praticamente perfeito e efetivamente servem ao objetivo de ajudar a que haja uma melhoria na compreensão e um aumento do vocabulário. Um exemplo disso é um vídeo que tem circulado na rede, que é falado em Inglês e tem legendas em Português.Com a alteração do propósito das manifestações, que deixaram de ser apenas contra o aumento da tarifa dos transportes públicos em São Paulo, passa ndo a ser contra o desgoverno de dinheiro público na construção de infraestruturas para os eventos e um apelo pela melhoria de serviços de saúde e educação, o fluxo de material em Inglês se manterá bastante alto seja por grandes jornais e cadeias de televisão internacionais ou indivíduos que querem que aquilo que têm a dizer seja entendido por um público maior. Particularmente, acredito que esta é uma ótima oportunidade que não deve ser desperdiçado por quem pretende sair da sua zona de conforto e quer começar a treinar e/ou ampliar os seus conhecimentos de Inglês diariamente.

Decoding an Odd Number Score on your SAT or ACT Essay

Decoding an Odd Number Score on your SAT or ACT Essay 3 Possible Reasons For An Odd Number Score on your SAT or ACT Essay Many students dont understand the scoring system of the SAT or ACT essays and, although the formatting of the essays are different, the grading of the essays are virtually the same talk about this with your Orange County ACT tutor before taking the test. Two graders will read their essay and their final score will be out of 12. Each grader will give a score between 0 and 6. It makes sense that most graders would give the same score but some have differing opinions. This is where the odd number scoring comes into play (READ: February ACT Study Timeline: 7 Steps to Success). A lot of students shoot for a score between 10 and 12 on their essay. A score of 10 or higher is very impressive and can put students into an entirely new category of writing skills. So what happens if the student gets a 9? This means that one grader assigned a score of 4 and the second assigned a score of 5. Receiving an 8 â€" meaning both graders gave a 4 â€" is a decent score. However, achieving a 10 would be much safer for college admissions. So how can a student improve if one grader thought their essay was above average and the second thought their essay was near excellent? Although, of course, we cant speak to these graders personally, as educators and students we can make a good guess. 1. One of the graders is picky about punctuation and spelling and the other is not Although graders follow a very strict grading rubric they are permitted to use their expertise to some degree. Some graders are extremely picky on spelling and punctuation errors while others will find that, if the content and flow are excellent, a spelling error here or there is not the end of the world. So how can a student fix that? Its safe to assume that any particular grader will be picky about spelling, which means that a student who received a score of 9 should be absolutely sure that their punctuation and spelling are up to par. They can review this on their own or with a tutor (READ: Cracking the ACT Science Section). 2. The essay may have contained clichés Some graders are not concerned with reading about the same content over and over again while others get bored very quickly. Students who are using common historical examples such as the Civil War, World War II, or the Civil Rights Movement may consider finding additional things to write about on the SAT. If the grader is reading about the Civil War in 300 essays in one day, they may grade an essay down for lack of originality. The solution for SAT students is to make a list of multiple yet lesser-known historical events that they can write about when they take their test again. 3. The student didn’t use enough varied vocabulary Many students do not use as much varied vocabulary as they should, especially on the ACT. ACT students are given a more real life (often easier to write about) prompt, but they still have to use impressive vocabulary to break a 10 (READ: 5 Reasons Students Should Blog). One grader may find that two or three impressive words and varied structure is enough while another grader may not be impressed. Students can cope with this issue by spending a couple of hours on Thesaurus.com. Knowing the correct synonyms for many basic words can help them develop more impressive yet appropriate vocabulary on their next essay. It is recommended that students make a list of about 10 words, 3 positive words (such as “happy”), 3 negative words (such a “sad”), and 3 additional adjectives that are used in everyday language (such as “interesting”). They can then find multiple synonyms and antonyms for all of these words and memorize them to use on their next essay. Students who have an odd score on their essay, especially if it’s a 9, should work diligently on their own or consult their tutor to see if theres any way they can get that score up to 10. As far as many colleges and universities are concerned, the biggest, and most impressive, jump is between a 9 and 10. Dont hesitate to book your private Orange County ACT or SAT tutor this winter!

Common Core and School Math

Common Core and School Math Common Core and School Math The goal of the Common Core State Standards is to ensure that students will be college- and career-ready in their skills and knowledge by the end of high school. A secondary purpose is to have consistent criteria of grade-level expectations in English Language Arts and Mathematics across states. In the 2015-2016 school year, 42 states are officially utilizing the Common Core standards in math, but this is expected to decrease as some states have repealed the standards. The shared learning goals do not constitute a national curriculum. They are a list of the skills students need to know by the end of specific grade levels from K-12. The standards do not explain how content should be taught nor do they recommend what materials to use. Each state and/or school district decides what school curriculum and sequence of skills to develop in order to comply with the state standards. Because schools use different curriculums, how concepts are taught may vary widely in neighboring school districts. The Common Core standards for math were designed using the following guidelines. Rather than racing to cover many topics in a mile-wide, inch-deep curriculum, it aims for teachers to narrow and deepen their math focus. The key domains, algebra and geometry, are introduced as early as kindergarten and are featured throughout the grades. Other important domains are measurement, numbers, operations, functions, statistics, probability, and modeling. These standards are intended to be cohesive by connecting topics from year to year. The standards aim to rigorously teach with equal weight: conceptual understanding, procedural skills and fluency, and application of mathematical ways of thinking. To achieve these aims, word problems are embedded throughout the school grades, and children are expected to explain why their answers are correct. Children learn a variety of ways to solve a problem, and calculator usage is widespread. Some critics say schools have lost sight of the Common Core aims to develop procedural skills and fluency as calculation ability is no longer emphasized in the classroom.

How To Handle Job Rejection

How To Handle Job Rejection Photo by rawpixel.com from Pexels Do Not Take It Personally The best thing a college student can do when being rejected for job after job after job is not to take the rejection personally. A student cannot blame themselves or think that something is wrong with themselves or that they were not good enough for a particular job. Odds are, they were good enough. But there are always so many other factors at play in these kinds of situations that a student cannot predict or plan ahead for that affect these decisions. Perhaps you had all the requisite skills needed, but your schedule was not the best match. Maybe one of your references never returned the potential employer’s calls. Maybe after they opened up the position to applications, they discovered they had someone working for them already that was suited for the job. Maybe they decided to hire no one for the position. Maybe someone applied that got vouched for by someone who already worked at the company. The list could go on and on. There are so many reasons why someone might not get hired that have absolutely nothing to do with their application, their skills, or anything that actually has to do with them and what they have to offer. Nothing they have personally done affected the final outcome, so in turn, college students should not take these rejections personally either. Just keep powering on and applying for those jobsâ€"you will get one of them as long as you keep trying and do not allow yourself to get discouraged! Photo by Moose Photos from Pexels Avoid Burning Bridges Another important aspect of handling job rejections is to avoid burning any bridges through your rejection. How could I be the one to burn a bridge? They are the ones who rejected me. They have burned their bridge with me rather than the other way around! You might be thinking. However, not accepting your rejection with grace could lead to you burning your bridge with this company. You could burn a bridge with a company by being rude or belligerent when rejected; by refusing to accept the no you received; by insulting the company or calling out employees.
