Discover How An Environmental Chemistry Degree Can Help You

Discover How An Environmental Chemistry Degree Can Help YouMany people take an environmental chemistry degree because it offers the same level of education as other chemistry degrees. For the most part, this is true. The fact that these degrees are going to be as similar as they are makes sense as all the basic building blocks are the same. However, a lot of other people take these degrees because it offers them an opportunity to really make a difference.Environmentally friendly living is important to everyone and in order to keep our overall health at the highest level possible, the kinds of energy sources used have to be changed. Not only does it help keep us healthy, but it's also good for the environment and therefore keeps everyone's health and well being in line. This is where the role of a natural science major comes into play.Environmental scientists are able to use the knowledge of chemical compounds to produce remedies that restore nature and clean up the air we breathe. En vironmental chemistry students get an education in the sciences that is totally unlike any other. They learn how to test and use chemicals and their properties in order to determine the effects that chemicals have on the human body.There are plenty of ways that a person can benefit from a degree in environmental chemistry. Because the science of working with chemical compounds can come in handy with practically every career, this means that a person who works in this field could easily transition into a variety of different fields. Environmental chemistry is a broad field, which means that it can apply to just about any field of employment that uses any kind of chemical compounds, including medicine, engineering, the military, agriculture, and more.An environmental chemistry degree also allows people to provide hope to the many communities that suffer from the effects of pollution cleanup. Many times people are willing to pay huge sums of money to fix the air quality in their commun ity, which is why a lot of people see this as a career path. In fact, many people actually enter the field after having college degrees in other fields of study. In many cases, students with one bachelor's degree in their name will find themselves out of a job after finishing their degree.An environmental chemistry degree also shows that one is a good communicator. It allows people to work within a community where there is a need for a specialist in the field of chemical compounds. People who can communicate with people who are not necessarily aware of the world around them and are able to effectively explain their job function are usually best suited for this field.Finally, an environmental chemistry degree also shows that a person is motivated to help out. A lot of people see this degree as an entry-level position. This is a great reason to enter this field, because if you are able to offer services to those who don't even realize the scope of the problem that we face, then you ar e taking a proactive approach to solving the problem. This can include donating to the environmental organization that you work for, working in a non-profit organization, or even volunteering to help fix the environmental problems that we have.Basically, environmental chemistry is a degree that can benefit you in so many ways. Students who have this degree are often able to start their careers in places where they can make a significant impact on the world around them. This is a way for many people to prove that they are truly concerned about helping the world, and doing so in a way that they can maintain their own health while doing so.

Solving Linear Systems

Solving Linear Systems System of equations are more than one equations which contain the same solution. To solve a system of equations we require the same number of equations as the number of unknown variables. An equations can consist of one or more than one unknown variables with different coefficient numbers and constant numbers. Example 1: Solve the system of equations x - y = 15 and x + y = 25? Solution: The given equations are x - y = 15 and x + y = 25. Here x, y are the unknown variables. Substitute the variable x. From one equation x = 15 + y, substituting in the other equation. This gives 15 + y + y = 25; 15 + 2y = 25; 2y = 10; y = 5. Now substitute y = 5 in x + y = 25; x = 20. Hence the solution is x = 20 and y = 5. Example 2: Solve the system of equations x - y = 11 and x + y = 7? Solution: The given equations are x - y = 11 and x + y = 7. Here x, y are the unknown variables. Substitute the variable x. From one equation x = 11 + y, substituting in the other equation. This gives 11 + y + y = 7; 2y + 11 = 7; 2y = 18; y = 9. Now substitute y = 9 in x + y = 7; x = -2. Hence the solution is x = 9 and y = 2.

Waves Sound and Ultrasound

Waves Sound and Ultrasound What is Sound? And What is Ultrasound? ChaptersWhat is Sound?What is Ultrasound?The tapping of footsteps on floorboards. The growl of a car out on the street. The distant rumble of an aeroplane.Each of these is a sound. A sound of which you can’t see the source, but which you recognise immediately. Maybe â€" like the plane â€" it is a sound which is produced literally miles away. Or maybe â€" like the footsteps of your neighbour in the flat upstairs â€" it is a sound which comes from the most accidental of things.Even if you put a glass of water down on a table, there is a sound. If you scratch your head, you can hear it. And if you type away on a keyboard, a sound is produced there too.Sound is literally everywhere. It is almost impossible to avoid. The whole world, in fact, seems to endlessly vibrating with different noises and disturbances â€" the birds or the rain, people’s voices, the wind. We are constantly surrounded with sounds â€" sounds that we hear and sounds that go unheard.But what is sound? What is actua lly happening when you can hear something? And how on earth does that sound actually arrive however far to get into your ear?These are the sorts of questions that we will be discussing here. Along with the rather more cool-sounding thing known as ultrasound â€" with all its different uses.Let’s take a look. What different sources of sound can you think of?

(Transverse waves, on the other hand, create displacements that are perpendicular to the energy’s direction.)So, imagine that plane in the sky. Although it is fairly far away, you can hear it. That’s because its engine produces vibrations which propagate energy all around them. And given that that energy meets no resistance, it can come all the way to your ear.That, in short, is the science of sound: movements of energy that make particles in the air vibrate. However, let’s go into a bit more detail.You can find more about the nature of waves - and the properties of waves - in our other article.What is a Sound Source?A sound source is where the sound begins â€" whether that be the pulsing diaphragm of a speaker, a human voice box, or the mechanical whirring and grinding of a machine. These places â€" i.e. everywhere â€" are the sources of the sound waves that then begin to propagate through the medium.How t hese work depends on the specific nature of the source. So, with a speaker, the technology within the speaker converts electrical energy into vibrations of particles, which cause all the particles around them to vibrate too. Meanwhile, the air rushing through your throat causes your voice box to vibrate, again making everything else around it vibrate too.As you can see, then, sounds all start with vibrations â€" a particular type of energy being converted into this kinetic energy. And once this vibration starts, it can spread through lots of different media to your ears.Learn about transversal and longitudinal waves!How do Sound Waves Travel?When a sound source vibrates, it makes everything else around it vibrate too â€" as the sound energy propagates outwards from the source in waves of rarefactions and compressions.A sound wave is a type of mechanical wave, meaning that it has to have a medium through which to pass. Sound cannot travel through a vacuum â€" as it needs the vibratio n of atoms to transfer its energy. Given this, we might see that sound travels at a different pace depending on the medium through which it is travelling.Sound travels through the air at a rate of 330 metres per second. This is known as the speed of  sound. However, the air â€" given that gas is a state in which the atoms are actually least densely arranged â€" is the medium at which sound travels the slowest.Waves of sound travel much more quickly through solids than both liquids and gases. For comparison, the speed sound travels through aluminium is 6320 m/s. That’s twenty times faster than through air. You know this intuitively actually â€" because when you put your head to a table and someone knocks on it, it is much louder than it would be if you were sat up straight.This is because the molecules in solids are generally much closer together than in air â€" and so the energy is much more easily transferred from one molecule to the next.Check for a math and physics tutor here.E choes.However, when there is a change of medium through which the sound is travelling, some of the sound will be reflected â€" in something known as an echo.So, if you shout into a tunnel, the sound will travel through the air â€" and some of it will return to your ears after contact with the interface between the two media, the air and the solid wall.If you want to learn more about reflection, we have an article on reflection and refraction. Guitar strings produce waves when plucked - and then sound.What Changes a Sound’s Pitch and Tone?So, we know what a sound is by now: it’s a vibration in a medium. Yet, an important question remains: how come we hear different sounds with different levels of loudness? And how come, when we listen to music, we can hear all sorts of different pitches and tones?To understand the answer, you need to remember that ‘sound waves’ are not singular, self-identical things. Rather, there is a whole spectrum of different sound waves, of an infinite variety of different sizes and speeds.Frequency is the word that refers to the number of times a wave oscillates â€" or goes from peak to trough to peak, or from compression to rarefaction and back â€" in a given time. The higher the frequency â€" i.e., the faster the wave oscillates â€" the more high-pitched the sound we hear.Amplitude, meanwhile, is the word for the size of the displacement that the wave creates. The larger the amplitude â€" meaning the more energy transmitted by the wave â€" the louder the sound.And Tones?This, however, doesn’t explain the tone of a sound â€" or the way that a guitar sounds different to a piano, or the way your voice sounds different to someone else’s.This particular fact owes its explanation again to the fact that sound waves are not singular.If you play a guitar string, it is not just one type of sound wave that is produced â€" not one wave with one set amplitude or frequency. Rather, that string will produce lots of different sizes and speeds of wave â€" and it is the particular combination of these that produces that specific tone.What is Ultrasound?Ultrasound might sound like it is something a bit more interesting. However, the ultrasound and sound are essentially the same things.The difference is that what we refer to as ultrasound is the sound waves with frequencies that the human ear cannot hear. If the range of human hearing stretches from twenty Hertz to twenty thousand H ertz (Hertz being the measurement of a wave’s frequency), ultrasound is anything above a frequency of twenty thousand.There is, quite honestly, an awful lot of sound that classifies as ‘ultra’. As in, there is actually more ultrasound than sound itself. But, given that we are humans, our categories tend to be determined by specifically human concerns.Dogs, on the other hand, whilst they are not categorising anything scientifically â€" at least, as far as we know â€" can hear a much larger range of sounds than humans. Their range is actually twice as large as ours â€" which makes the distinction between sound and ultrasound rather arbitrary.What do We Use Ultrasound for? And How does it Work?The most common use of ultrasound is for creating images of babies in the womb. This technology is made possible by the process of reflection.Ultrasound works because there are lots of different sorts of material in your body: fat, muscle, bone.By using a tool that can both emit and detect sound waves, the process of ultrasound can essentially build images by receiving reflections â€" or echoes â€" from the interfaces between the different layers of material.So, at the interface between fat and muscle, some of the emitted sound waves are reflected and detected. At the interface between muscle and bone, the same thing happens. All of this can then be compiled onto a computer and an image can be created from the detection. We use ultrasound to see babies in the womb.

How You Can Benefit From A Biology Tutor

How You Can Benefit From A Biology Tutor Taking Lessons for Biology Revision Chapters10 Great Reasons To Take BiologyHow To Find A Biology TutorHow to Choose The Right Biology TeacherHow Much Do Biology Tutors Cost?Studying Biology is not just for those who aspire to be doctors, it is a subject that has the ability to appeal to the masses. Yet, despite offering fascinating and, at times, mind-blowing content to learn and explore, many do not realise just how many different career paths Biology can open up for them.Referred to as the 'science of life', Biology is a science that explores all living things, including humans, animals and plants. As such, a biologist does not necessarily have to specialise in the human body and its many ailments.However, if that is what interests you, then this course studied at A Level alongside another subject such as Mathematics, Physics or Chemistry could enable you to apply for your medical degree.But you must get your GCSE exams out of the way first, and to enrol on a science course at college as part of your A Level studies (or International Baccalaureate, if that is the course you decide to embark on), then you must not only pass your Science GCSE, you must excel in the field.As mentioned, Biology does not necessarily mean a study of the human body, it can also relate to all other living organisms on our planet. Therefore, if you are particularly keen on nature, gardening and learning how things grow in and above ground, then Biology can help to answer many of your questions and theories.Find an A level biology online course here.Biology teaches you about living organisms, among other fascinating things. Photo credit: Five Acre Geographic via VisualHunt.comNot only can it educate you on the environment, it might even have the power to make you think differently about your surroundings and appreciate how fascinating life is.Furthermore, Biology focuses on animal species, teaching pupils how they evolved, dividing them into categories, detailing how the make-up of their cells distinguishes them as thes e types of organisms and also explains how they feed.8. You can better understand how to take care of the environmentBy learning about how vegetation and other plant life thrive, you can learn how to take care of the environment around you.9. You will receive accreditationThose who study Biology to a high level, for instance at degree-level, will receive accreditation for their qualifications and expertise. Science graduates are awarded with a B.Sc., or Bachelor of Science, which can then lead to a M.Sc., or Master of Science for post-graduates.10. It is important to societyMuch of what we know about our race, animals and plants has come from scientific research. As such, scientists are very important to our society. Biological research needs fresh, talented biologists to continue to drive this research forward and help in the development of cures for terminal illnesses, as an example.How To Find A Biology TutorWhether or not you struggle to keep up with the complex principles conta ined within Biology topics, a tutor can help you to significantly improve your understanding of the concepts and thus get you a much higher grade than you otherwise would have achieved.That said, where do you find a tutor who is not only qualified and knowledgeable, but who is familiar with your course structure and the examinations that you are ultimately working towards?First of all, you should know that your neighbour, with his grade B GCSE may be able to help you out with simple tasks like homework but only a professional tutor can really move your learning along.As such, you should be looking for somebody who has a proven record as a tutor in this subject. In many cases, tutors are past or existing teachers with knowledge of the subject as well as the syllabus being taught, which is why your school or college may be a good place to start your search.Consult your Science teacher to see if they know of any biology private tutors who could help you during your course, or ask aroun d among your peers and their parents, as a recommendation is always a great place to begin.Asking somebody you know to be your tutor is not necessarily a bad thing, however you should be certain they are suitably qualified. Not only can an uninspiring or under-qualified individual cost you your good grade, they could wind up costing you lots of money that would be better spent elsewhere!If you have no recommendations and decide to turn to the Internet in search for biology a level tutors, then make sure that you only browse genuine websites of candidates with the necessary skills. Our site, Superprof, features a long list of educated tutors covering a wide range of subjects, including of course Biology and its different subcategories (Marine Biology, Zoology, Ecology, are just some examples).Superprof offers a range of qualified tutors covering all subjects, including Biology. Photo credit: US Department of Education via Visual huntHow to Choose The Right Biology TeacherAs suggested above, one of the main things to remember is that you should always make sure you know your tutor’s educational background. For instance, if you know or find a tutor who specialises in Chemistry, they most probably don’t have the precise skills and knowledge required to successfully tutor you to a successful grade in Biology.References are a very good way of differentiating the services available. Most experienced tutors will have taught enough pupils to be able to provide some feedback on their tutoring approach.If you found your tutor by word of mouth, be sure to ask questions to the person who referred them and find out if they have a website or profile you can look at online. If, however, you have come across what appears to be the perfect tutor online then read their reviews and don’t be afraid to contact them to ask them some questions before you enter any agreements.It is also a good idea to interview your chosen candidate to make sure that they are the fit for you and your studies.Remember that, to keep the momentum going, you should ideally be having at least a two-hour session once a week (or perhaps just an hour if you under 14 and not studying towards a recognised, mainstream qualification) so if your preferred tutor can only fit in one or two short classes in a month, then consider looking for someone who can accommodate your needs. With tutoring being a relatively short-term process, you should be seeking maximum impact to ensure long-term gain.Finally, it is really important to make sure you have a rapport with your tutor, as nothing can be worse than dreading your next appointment. This is why a personal recommendation or meeting with the tutor in person can have a positive impact on your attitude towards tuition.How Much Do Biology Tutors Cost?Despite what you might think, tuition does not have to cost an arm and a leg. This is particularly good news if your parents or guardians are unable to support you financially or if you make the d ecision to pay for additional classes yourself.Privately hired tutors can cost in the region of £20 per hour, however anything less than this and you should hear alarm bells ringing.If you decide to consult an agency that specialises in hiring tutors, you can expect to pay anything upward from £40, with some very qualified members costing as much as £60 an hour.Find out more about the cost of biology tutors.

Key Steps To Easing Career Anxiety When Starting A New Career Path - Introvert Whisperer

Introvert Whisperer / Key Steps To Easing Career Anxiety When Starting A New Career Path - Introvert Whisperer Key Steps To Easing Career Anxiety When Starting A New Career Path Starting a new career is a daunting, yet exciting journey to begin. There are so many new things that you’ll be learning, seeing, and achieving that you’ll really excel in life. However, while it may be a good thing to change careers, it doesn’t mean that you won’t face the onset of anxiety when your career changes. If you’re currently experiencing career anxiety, this guide will give you the top tips on how you can help ease your anxiety when starting a new career path. Let’s take a look. Top Tips To Help Ease Career Anxiety Understand What You’ll Be Doing One of the common reasons why you’ll become anxious when changing careers is because it’s the unknown. The unknown is fearful and can make you feel like you’re not in control. To help ease this fear, it’s important to read more about your new job and understand what it entails when you begin. The more you understand what you’ll be doing, the less anxiety you’ll have. While understanding what the job is about, don’t forget to remember why you applied for the job in the first place and what skills you have with the new job. Don’t Expect To Know Everything When starting a new career path it’s important to remember that you won’t know everything the job requires of you. You won’t have all the skills and this is ok, while working in the job you’ll begin to learn more about it. People who start a new career tend to feel like there are high expectations of them to know the ins and outs of what is required. This isn’t true. As long as you have the basic skill requirements you can learn the rest along the way. Remember you won’t be new at your job forever. Write Down Your Thoughts When you have anxiety and you’re constantly thinking about your new job, sometimes it’s good to write down your thoughts on a piece of paper. The idea of writing down your thoughts on a piece of paper is to help you to free up your mind. Generally, when you’ve written your thoughts down, your mind doesn’t need to keep remembering them because it knows you’ve got a copy of them. This helps to ease your mind and helps you to relax somewhat before you begin your next new adventure.
