The Importance of Molecular Mass Definition Chemistry

The Importance of Molecular Mass Definition ChemistryMolecular Mass Definition Chemistry is becoming more important in the field of science. With more work going into understanding how molecules form, many researchers have been forced to try and come up with new ways to study them. This has been brought about through a number of different methods.Mass is one way of defining an element. One of the biggest challenges faced by chemists has been the ability to determine the atomic structure of all the elements in the world. When scientists have studied the atomically solid masses of a substance, they can work out the atomic weights of the atoms within the substance. This is done by taking advantage of radioactivity to help them measure mass.Another method of determining the molecular mass of a substance is through chemical bonding. For this process the chemist has to use a technique called ionic liquid chromatography, which is also known as ILC. The ILC allows the substance to be 'sorted ' into molecular masses and bonds can then be deduced from these masses.However, while molecular mass is an important scientific quantity, it is not necessarily used as a means of simply observing how things move. Another more complicated type of mass measurement is atomic force microscopy. This is a different method of studying molecules that allow them to be seen much more clearly than they could be through any other method.Using a microscope lens, a layer of liquid is placed onto a small sample, whilst a microscope probe is attached to the sample. The layer of liquid forms around the probe and then passes through the lens. The flow of the liquid through the lens then reveals the atomic structure of the molecules.When a sample is placed onto a glass slide the width of the sample can be increased, whilst the length can be decreased. This creates a pattern on the surface of the slide that can reveal the molecular structure of the sample. The closer the pattern, the better the pictur e can reveal.Other types of mass measurement include electron spin resonance. A crystal of aluminum reacts to a change in the level of the electrons on the surface of the crystal, and when they are all very close together the electron spin resonance gives a much clearer picture of the arrangement of the electrons.

Reasons to Study Geography

Reasons to Study Geography Why You Should Study Geography ChaptersThe Study of GeographyWhat a Degree in Geography Will Prepare You forGCSE Geography is of Vital ImportanceWhy Study Geography?A show of hands, please: how many of you know anyone who is a geographer? We’re guessing there are no hands waving in the air... right?That is because so-called geographers go by many other names; names we are much more familiar with, such as ‘oceanographer’ or ‘climatologist’ or ‘GIS specialist’.Most people believe attaining a geography degree will not provide competitive job opportunities.In fact, some people think that, now that the entire world is mapped, geography should be relegated to an academic exercise and nothing more!Nothing could be further from the truth...Geography is regarded as the mother of all sciences both for its far-reaching subspecialties and for its long history, which began as simply as someone thinking ‘What lies on the other side of that hill?’Have you ever done that? Been somewhere, in an urban landscape or on holiday in unfamiliar territory and been beset by the urge to explore and discover?Superprof taps into that very human urge to prospect, to examine; to investigate and uncover reasons why the study of geography is as vital today as when the first humans migrated out of their Cradle of Civilisation.eruption of Anak Krakatoa in Indonesia makes a timely and excellent case for the need to study landforms and coastlines.Since the eruption, the island has been reduced to about a quarter of its size, clearly proving that our earth is dynamic rather than static.That being the case, shouldn’t such changes, no matter how incremental, be studied, recorded and compiled?Another phenomenon that illustrates this point succinctly is Italy’s disappearing coastline.That observation was not casually made by avid beachgoers disappointed that the sea has taken over their favourite sandy strand but by people qualified to compile and analyse data.That eroding coastline surrounding the world’s bi ggest boot is attributed in part to global warming: the melting of polar ice caps causing sea levels to rise.That would mean then that climatologists and oceanographers should jump in the fray and work on solutions, right?However, the main cause of that coastline’s erosion is human activity: taking sand from the beaches to build ever more.The government is surely at fault here; allowing city planners to build so much!Would you be terribly surprised to know that all of the career fields mentioned above are  subspecialties of geography?Through a variety of disciplines, cataloguing earth’s natural and man-made changes is the purview of geographers.A background in geography will provide you with a steady career in regional planning Source: Pixabay Credit: Paul Br 75What a Degree in Geography Will Prepare You forGeography is a social science with many divisions.Studying geography as an undergraduate will indeed prepare you for a lot of different careers, but which branch of geography would you undertake?You may, for example, decide to specialise in physical geography; to learn about:Climatology: the study of weather conditions over long periods of time to provide predictionsMeteorology: analysing weather processes for short-term forecastingHydrology: studying the amount and quality of water; in a specific region or across the planetBiogeography: the pattern of species distribution and their effects on the environmentOceanography: the study of oceans and seasEnvironmental geography: studies the spatial aspects of humans’ interaction with the environmentThe flipside of physical geography is human geography; the study of people and their cultures, communities, economy and environment.An undergraduate degree in this discipline could lead you to a satisfying career in urban geography; laying out roads or mapping future factories.Other branches of this far-reaching humanities study include economic geography, cultural geography, social geography and applied geograp hy.Whether you relish the prospect of travelling all over our world or plan on staying local with an office career, as a geography major, you would certainly have a wide range of choices when it comes to working.Why just see how the study of geography has evolved from the days of Sir Francis Drake:If computers are your bailiwick, you could train as a geographical information systems specialist, a career in which you may opt for fieldwork or stay in an office, conducting an analytical study of datasets.In short, there is no shortage of career fields for anyone taking a geography course of study!GCSE Geography is of Vital ImportanceLondon is in... France, right? Eleanor Clarke, bank tellerConsidering how all-encompassing the field of geography is, it seems rather astounding that the subject is not a part of the core curriculum in our schools' later years.And it’s not just UK schools that have forsaken geography courses!A look at schools in America reveals the same state of affairs: the study of world regional geography, let alone learning about one’s own natural environment has taken a back seat to other sciences.The truth is brutal: no education in earth science will result in nobody being qualified to staff the many positions calling for such training. Who will manage earth systems for generations to come?Conservation and environmental problems are very real issues facing humanity today. Learning how to resolve them requires ongoing effort; a chain of dedication that involves everybody.Exposing our youth to the challenges they will face, such as climate change and environmental management, is the best way to introduce and engage them early in a strategic concern for the world they will inherit.Another reason to encourage environmental studies is to understand how common events impact different regions of the world.We are quite fortunate that we have many systems in place to protect us from natural disasters such as floods. Other parts of the world are not so lucky; their physical environment is impacted by environmental change, sometimes severely.In order to become well-educated global citizens, our students must have more than a passing acquaintance with the challenges that beset our and other societies.It is not enough to view documentaries such as the Blue Planet series or bandy about words such as sustainability and ecology.Our students need to understand the interrelationship of these concepts as well, so that they may be inspired to seek a science degree and work toward better earth stewardship for centuries to come.Let Superprof help you find a geography tutor!Consulting a GPS does little to develop your spatial analysis skills! Source: Pixabay Credit CFVIWhy Study Geography?With satellite-generated GPS, what do we need maps for?Perhaps people think that, because the world has been completely discovered and mapped, explorers are no longer needed and cartography is a dead science.Nothing could be further from the truth! Cartogr aphic skills are still highly in demand; classroom maps and atlases will never go out of style.Who do you think draws all of those maps and inputs geographic information for display on your GPS? Geographic information systems specialists, that who!Besides, it is a bad idea to rely exclusively on your GPS â€" which, again makes the case for studying geography!Doing so will help you develop exquisite navigation skills by helping you to build spatial relationships.Just as explorers of old navigated by astronomy â€" the position of the stars relative to their current place, you too could cultivate such a geospatial intelligence by studying the unique features of any environment you find yourself in.Let us say you are a graduate student preparing to study abroad. How would you get ready for such an adventure?Might you consider the cost of a geography tutor in your plans?You would listen to news reports, become more than mildly curious about other cultures and develop a fascination for en vironmental science with regard to the new region you will find yourself in.Will there be a lake to swim in? How about hiking trails? What about urban development: are you going to a big city or a smaller town?By the time you return from you stay away, you will have surely realised that your experience and geographical studies have helped you understand the phenomenon of globalization on a deeply personal level.Which, in turn, furthers your grasp on world geography and cultural consciousness... and that is exactly the type of understanding we need to cultivate!The study of geography represents humanity’s future safety in a changing environment as well as an understanding of our history.If you want a better grasp on world history, you should start by digging into geography!A geography program of study promises career stability full of excitement and engagement as well as an understanding of global ecological systems and how we humans impact them.For better or worse...Why wait? Lear n more about what geography courses can do for you and for our world!

Reputed institutes have Online tutoring for elementary school students service

Reputed institutes have Online tutoring for elementary school students’ service School days are always like a rainbow which covers different colours of our lives. It is the phase where we from an innocent toddler grow up to an ambitious teenager. School teaches variety of things. It helps in shaping up our lives in a new way.

One Week Traveling in China - The Scenic Route

One Week Traveling in China - The Scenic Route If you’re teaching abroad in China or elsewhere in Asia, be sure to find the time to travel through China. Earlier, we posted a possible itinerary for exploring Beijing and Shanghai, but there’s much more to experience in China. Take a look at the following one week travel itinerary of a trip to the Guangxi province of China.Day 1 - GuilinTo begin your trip to China, fly to Guilin. Home to 12 ethnic minorities, Guilin lies amongst lakes, rivers and picturesque limestone karsts. First off, head to Elephant Trunk Hill. The hill with a natural hole has become the symbol of Guilin; a boat tour will get you the best view.Day 2 â€" Rice TerracesGet up early and head to the rice terraces of Longsheng, about a 2-hour bus ride from Guilin. Set among small villages, the terraces are an incredible sight year around. In the spring, the flooded paddies resemble scales, giving the ridge its name of the “Dragon Backed Mountain.” Hiking through these terraces will give you a stunning view of the rice fields and surrounding hills.Day 3 â€" Li River CruiseYou’ll have already seen some incredible scenery on this trip, but this river cruise will take your breath away. Boats slowly guide visitors down the Li River, through picturesque hills, rock formations and past scenes illustrating rural life in China. A guide will make the landscape come to life with legendary stories and myths. Once you arrive in Yangshuo, stroll through the small town, enjoy some fabulous food, and explore the night market. If you’re an outdoor enthusiast, consider staying for another day for a bike ride through the scenic countryside or a great climbing excursion.Day 4 â€" Travel to Nanning and the Detian WaterfallsYou’ll need to travel from Yangshuo to Nanning â€" a half-day trip â€" in order to make your way to the China-Vietnam border to see the famous Detian Waterfalls (Ban Gioc in Vietnamese). Find a train or bus to Nanning, and spend your afternoon relaxing and enjoying the tropical scen ery at South Lake Park.Day 5 â€" Detian WaterfallsThe Detian Waterfall will be worth your travel efforts. The world’s second largest transnational waterfall flows through three terraces and several scenic routes take you to some beautiful spots. Additionally, visit the border between and Vietnam and China at the 53 Boundary Marker and Cannon Mountain.Day 6 â€"BeihaiMake your way to the fastest growing city in the world, Beihai. It’s well known for its 15 mile long Silver Beach, so make sure you’ve packed your swimsuit! The old street in Beihai features colonial buildings, and the Underwater World highlights the area’s rich marine diversity and China’s naval history. Make sure to try a variety of delicious local seafood for dinner.Day 6 â€" Return to GuilinAfter making your way back to Guilin, take time to explore the city. Stroll through the underground markets to pick up any souvenirs, and watch the artificial waterfall in the large city square at night.China, a vast and diverse country, features more incredible sights than visitors can explore on one short trip. You could plan a hundred different travel itineraries through the country, and the best way to see them all is to spend time teaching abroad in China!See also:One week traveling in IndonesiaOne week traveling in Germany  Header photo credit: By akiwitz, via FlickrDetian Falls photo credit: By jankgo [CC-BY-2.0], via Wikimedia Commons
