An Introduction to Biology and Chemistry

An Introduction to Biology and ChemistryChemistry and Biology are intertwined in the work of Naturalist Robert McElvaine and biologist Henry T. Timberlake. They were both involved in keeping their students updated on various aspects of the field of natural science. The reason for doing this was to provide the students with more knowledge so that they can be better prepared to handle the demands of their jobs later on.Biology and Chemistry are very important in determining the overall structure of living things and what their responses to different factors in nature are. Chemicals in nature, especially those that occur naturally, are used by organisms to achieve their own needs, whether they're a species of algae, a worm or a bacterium.Most of these chemical compounds are very similar to those found in the air and the water on earth. There are a few exceptions which differ from the natural state of these compounds, but the general principles remain the same.The chemicals in the enviro nment also help organisms to digest food, produce toxins, grow and reproduce. It would be easy to assume that chemical compounds in nature are not necessary, however they are one of the things that the body relies on. The body can function and use a certain amount of chemicals.Chemical compounds are essential for living things to survive. Some organisms can survive without other chemicals, but not with them. However, most life forms can survive without a large number of chemical compounds.If you want to learn more about Biology and Chemical and Biological Chemistry, the best option would be to take a class where you will learn all about them. The classes offered by The University of Texas are very good sources of chemistry and biology classes that you can take. These classes teach students the basics but also give them great practice so that they can understand more advanced concepts when they go to school.This makes them ideal for students who want to learn more about Biology and C hemical and Biological Chemistry in the course of their studies. When you join an online class, you are taking a traditional class and learning the course material and techniques in a classroom setting. The methods of teaching and learning will differ from an online class to that of a traditional class, but the fundamentals will remain the same.Teaching students about Biology and Chemical and Biological Chemistry through online classes like this allows them to gain invaluable experience. This knowledge, coupled with basic knowledge about the process of learning and doing science, will make them much better scientists and better professionals in their future careers.

The History Of Vegetarianism

The History Of Vegetarianism Vegetarianism: A History ChaptersEarly Man: The Hunting InstinctBefore Christ: Religion And Vegetarianism1700-1800s: A More Romantic Take On The Feelings Of Animals1800-1900s: The Birth Of The Vegetarian Society1900-2000s: Modern Day VegetarianismWhile you might think that vegetarianism is quite a recent ideology, the fact is that people have been eating plant-based diets for as long as they have been eating animal products like meat, eggs and dairy products.Views on a vegetarian diet differed, and continue to differ, in different parts of the world and across the different faiths.Religion has played a very big part in both the undermining of animal species and in overturning the outlook that humans are superior to creatures.Keep reading to find out more about the history of the vegetarianism movement and who played a major role in driving it.the first to show independent thinking concerning animal cruelty, and argued that all species on the planet should have equal rights.But before him, ancient Egyptians a nd Babylonians had long-practised a vegetarian ideology as part of their religious beliefs, which meant that they abstained from eating and wearing any animal-derived products. This was rooted in their nature from as early as 3,200 BCE.But it was Pythagoras himself who took it upon himself to champion the health benefits of a vegetarian way of life and, as we know, he was not a stupid man. Though his scientific evidence was lacking, he viewed a life abstaining from animal products not only as a way to co-exist peacefully on Earth, but as a way to benefit the human: by giving them purity of the soul.Other famous Greek names opposed this view, including Socrates, Plato and Aristotle who all firmly believed that animals were put on Earth to be slaves, and therefore had no place other than to become meat for us to eat or clothes to wear. They had very limited sympathy for the butchering of them for meat, and thought Pythagoras' views weren't worthy of recognition.Back in the day, many h ad no sympathy for the animals being slaughtered, even if it was in a barbaric way. Photo credit: Farm Sanctuary on Visual HuntWhile kindness to animals has long been a part of Eastern religious beliefs, for instance in Ancient Egyptian mythology where some  animals were seen as sacred gods,  Christianity saw humans as the superior living species and thus anyone who disagreed with this notion was seen as deviants or fanatics and were even persecuted for voicing their opinions.

Leonardo Da Vinci, the famous painter and inventor, was repulsed by the thought of animal slaughter, as were many classical writers of the time. They touchingly put into words the powerful notion that animals could indeed feel and think, just like humans.John Clare, for instance, wrote about a badger that was captured and baited in his poem titled Badger, meanwhile Ted Hughes remarks on the fate of pigs in a slaughterhouse in his poem View of a Pig. Da Vinci often used wild animals as the subjects of his studies and drawings.With the Enlightenment period of the 18th centu ry came more opposing views on the place of humans and animals in the order of creation, with some arguing that animals were soulless robots and others debating that they were intelligent creatures that could feel and communicate. At this time, slaughter methods were truly horrific.1800-1900s: The Birth Of The Vegetarian SocietyIn the 19th century, romance prevailed and in 1809, a noteworthy move towards vegetarianism as part of Christian faith was established. From this day on, many began to appeal against meat eating, using biblical references to back up their theories.In 1847, in the UK,  The Vegetarian Society was formed and by the 1880s, vegetarian restaurants had began to pop up across the capital making nutritional, vegetarian meals easier to come by. This meant that followers of the cause could celebrate the vegetable with other like-minded individuals within their community.Finally, with British health still severely inadequate, The Vegetarian Society would send food to dep rived communities in an act of humanitarianism to help save the people.The food shortages in the meat industry that resulted from WWII meant that people were encouraged to dig to source food, and many therefore lived on a near-vegetarian diet throughout the war. In 1945, approximately 100,000 Britons were vegetarian.Food parcels during the war would have included bare essentials to keep people alive. Photo credit: HereIsTom on Visual Hunt1900-2000s: Modern Day VegetarianismToday, the society believes that the number of committed vegetarians has risen to almost 2million, and thanks the shops and supermarkets that stock frozen vegetarian goods like quorn mince and tofu pieces for this growth. Without them making ingredients for vegetarian dinner recipes so accessible, this number may be much lower.It was during the 1950s and 1960s that people started to become much more aware of their health and made links between how they could control their wellbeing by adapting their diet and other life choices. That said, cigarettes and other tobacco products were high in demand so scientists and health experts still had a long way to go in assessing what was good for the human body.Meanwhile, the 1980s and 1990s revealed the true devastation that humanity was having on the Earth, and so vegetarianism rose once again. More people began to take notice of other options available to them than animal protein and began shifting towards a meatless diet.Vegetarians today are campaigning for a change in the way that animals are treated, with animal experimentation and factory farming having already been brought to light. Not to mention the fact that they are striving to convince others of the benefits of going vegetarian, like the campaign National Vegetarian Week which takes place in May this year. The same can be said of the vegan community. Vegans abstain from all products that derive from animals. As well as avoiding meat, vegans do not consume eggs, dairy or use products that h ave been created at the cost of animal suffering.Anyone can join, even if they don't plan to continue with a meat-free diet afterwards. The idea is to highlight the health benefits of vegetarianism by encouraging people to try it out, in the hope that they will want to stick it out for longer and potentially become a permanent veggie.If this interests you, or you want to invite a friend to join you eating meat-free food for the week, then you can sign up for the campaign's newsletters which will be packed full of fantastic vegetarian recipes, helpful information and competitions throughout the course of the week.If, however, you don't think you can eat vegetarian dishes for an entire week, then why not try Meatless Monday, which is a gentler way to introduce a meat eater to meatless meals.Some of the recipes you could try are: stir fried noodles with tofu in a peanut sauce, macaroni and cheese with a spinach salad on the side, portobello mushroom wellington with roasted cauliflower and sprouts, goat cheese and caramelized onion quiche with Mediterranean roasted vegetables, Mexican bean chili with tortilla crisps and an avocado salad, sweet potato frittata with kale and asparagus, cheesy cannelloni with a tomato salad, onion tart with carrot salad, curried potato curry with pickled chutney, grilled bean burger with a sweetcorn and carrot salad topped with a balsamic vinaigrette, pumpkin soup with bread to dip in, feta stuffed pepper with spiced couscous, black bean burritos with wild rice, mushroom and parmesan arancini (risotto balls) coated in fried garlicky bread crumbs... Or, if you prefer fast and easy recipes, then you could try things like avocado on toast, hummus with sliced peppers and pitta bread, tomato, onion and pesto bruschetta, vegetarian lasagna, or simple pasta recipes. You see, your healthy dinner doesn't have to be boring!You can find many more free recipes online, including vegetarian breakfast recipes, side dishes, puddings and, of course, more vegetarian  dinner recipes.Remember that seeds and nuts like pecan, cashews or pine nuts, for example, are great for adding texture. Also, if you really want to embrace a healthy lifestyle, then stop munching on biscuits for your mid-morning snack and instead crunch on some pumpkin seeds!That said, even vegetarians like to 'veg' out on the sofa with a tasty treat. So you can still enjoy a bowl of mozzarella and salsa topped nachos with friends - it is allowed!If you fancy trying your hand at creating your own fragrant and mouth watering meat-free dishes but are stuck for ideas to base your meal around, then you might be interested to know about these delicious yet less mainstream products that are great to cook with: quinoa, lentils, polenta, arugula, acorn squash, seitan, artichoke, orzo, gnudi, tempeh, farro salad, bok choy, yukon gold potatoes, okra and cremini mushrooms.While you might not find all of them in your local supermarket, you're sure to be able to source them fro m specialist shops that cater for vegans and vegetarians.Further Reading And LinksIf you found this article an interesting read, then why not read others on vegetarian cooking, such as:Tips To Be A Healthy VegetarianThe Best UK Vegetarian Food BloggersFind cooking classes

What is Guitar Technique And Why Does it Matter

What is Guitar Technique And Why Does it Matter Megan L. Whats the deal with guitar technique anyway? Guitar teacher  Alexander A.  explains a few of the fundamentals and why they are so important If your teacher is cracking the whip every lesson because your hands aren’t in the proper position you may be asking yourself, “Does my guitar teacher hate me?” The answer is “no” â€" at least, I certainly hope not! More than likely, your teacher is trying to make you a better player by guiding you to play with good technique. We’ll be looking at effective techniques to use for guitar and bass players, though these principals apply to most other instruments as well. Before we get into specifics, let’s talk about what were looking for and why. Power In case you haven’t noticed yet, playing music can be very physically demanding. Guitar and bass players face this demand with our hands, as this is our primary interface with the instrument. Ever play barre chords on guitar or an F# major scale on the low end of the bass? These tasks are challenging and require a great deal of power to accomplish. Much like in martial arts, power is not achieved with brute force but by taking every advantage we can find to deliver the most power with the least effort. This isn’t laziness; it’s a fundamental necessity of our instruments. Control Like they say in Spiderman, “with great power comes great responsibility.” I think Spiderman must be a rock star. But it’s true! All that power that you’ve harnessed will go to waste if you don’t have proper control over your strings. Among other things, this means letting them ring when they need to and being able to mute them when they need to be silent Energy Going green isn’t just for electric cars and paperless billing. Guitar players need to conserve our energy as well. Almost all players will push the limits of their physical stamina at one time or another, so it’s important to make every action count. Work with your hands, not against them. Simple Guidelines Here are some simple guitar technique guidelines for guitar and bass players. These just cover the basics, so be sure to ask your guitar teacher about progressing your technique by using more advanced methods when youre ready. 1) Fingers on the string When holding down a single note using the second, third, or fourth fingers practice using your other fingers to hold down lower notes at the same time to build strength. For example, if you play a C on the A-string with the second finger (third fret), the first finger should be holding down the note B at the same time (second fret). If you reach for the D above the C with the fourth finger (fifth fret), you should have all four fingers holding down the string. (Of course, guitarists will need to abandon this technique when playing chords.) By letting more than one finger do the work we are conserving energy and maintaining control over the string. If you are a new player (or just have some old habits to break) this technique will feel strange for a little while, but if you use it consistently you should be forming good habits within a few weeks. Before you know it you will have more power in your fingers; it will feel strange not to have all your fingers on the strings. Just stick with it! 2) Stay close We can further conserve energy and maintain control by keeping fingers close to the fretboard when not in use. Let your fingers “hover” over the strings just high enough to let them ring, but low enough to be ready for action! Reach for the stars with your music, not your fingers. 3) No negative angles We need to always have our finger joints at positive angles, curved as if holding a ball. One of the greatest losses of power for new players often occurs in the last joint in each finger â€" the one by the fingernail. They should never be bent backwards as this greatly diminishes your strength. 4) Maintain your reach Always maintain a reach covering three or four frets. If you play B-C-D on the A-string (in that order, one note at a time) your first finger should still be reaching the B (second fret) as your fourth finger plays D (fifth fret). By maintaining this reach and not letting the first finger “scrunch up” against the others we keep control over four frets of the instrument and conserve energy by keeping our fingers stationary. Energy, power, and control are all intertwined. What’s good for one is good for the rest. Let these pillars of success be your focus as you move forward with your guitar technique. Now, let’s rock!

The reasons can be var ious and argued, but one of the most important ones is because of what its made of.Oil paint consists of pigment mixed with oil, which not only gives oil paintings their vibrancy but also allows artists to pile layer on top of layer, sometimes without even letting the bottom layers dry fully â€" a technique discussed later.While using oil paints can be extremely rewarding, the medium is taught normally in more advanced courses. Because it tends to be more expensive than its counterparts, and because it uses turpentine as a solvent, it can be a bit more difficult to use or less accessible. If you’d like to start to learn to paint with oil paints, however, just make sure that you keep these factors in mind.Look for art classes in Manchester.Acrylic PaintingAcrylic is a relatively new type of paint, having only been created in the mid-1900s. Since its introduction to the mass market, however, acrylic paint has become a popular medium amongst both beginners and professional painters. The reason why can be found both in its affordability as well as its fast learning curve.While this type of paint might not sound familiar to you, some of the most famous contemporary works have been painted in acrylic. In the UK alone, it has been used by the likes of David Hockney and Eduardo Paolozzi in the notorious pop art movement. Because of its popularity, if you’re looking for some art education involving acrylic around Glasgow, you’re in luck.Finding painting classes in Cardiff and painting workshops in Belfast!Watercolor PaintingPainting with watercolors can, at first, seem to be a pastime of only beginner artists or older folks.

Complicating this further is the fact that sometimes, the same techniques can be called something completely different in different mediums. Here’s some of the most common techniques you’ll find yourself utilizing in every class and how, exactly, they’re performed.Try a painting class in Edinburgh too!Acrylic PaintingWhether you’re painting a still life or working on depicting a human figure, knowing a variety of methods to employ while painting can go a long way. One method that can also be found in both watercolor and oil painting is known as wet on dry.This technique involves thinning the paint with water and applying it to a dry canvas. This is one of the most common ways of using acrylic and will probably a technique you utilize often. Taking this a step further is a technique known as washing.Washing involves thinning acrylic paint out to the point where its application resembles that of watercolor. Painting in this manner can be extremely useful if you’re looking for a watercolor effect with fast drying paint.WatercolorsSpeaking of watercolor, this highly versatile paint can be applied in a variety of different ways. One of the most important, besides the wet on dry already mentioned, is a technique called wet on wet. While the names of these techniques seem a bit uninspired, the process itself is actually quite amazing.Wet on wet involves mixing your watercolor paint with water and applying it to a canvas that is already wet. In order to prepare the canvas, simply apply a layer of water over the sections onto which you would like to paint. The effects of utilizing this method can often lead to some of the more intense color mixing apparent in portraits and scenes like those of Cheng Kee-Chee’s.Oil PaintingThe wet on wet version of oil painting, other than having a different name, is also slightly different than its watercolor counterpart. Known as alla prima, this technique involves painting on top of layers that have not completely dried. Doing this doesn’t just allow color to mix in interesting ways, as with watercolor, but it also allows for textures to build up.Underpainting and glazing are equally as important techniques to get familiar with that happen at the beginning and the end of the painting process, respectively. Underpainting is the process of painting a layer of a neutral color onto the entirety of the canvas before painting your subject on it. In some instances, you can also sketch your initial painting in a monochrome of that same base color before applying the colors you will eventually use.Glazing, on the other hand, is utilized at the end of the painting process and can be seen as a sealing layer on top of the finished product. The technique involves nothing more than applying a coat of transparent paint on top of your painting as both a protective measure and to enhance the effect of the colors.Find painting classes in Leeds.Learning to paint can even lead to careers in artWhat Art Supplies Do You Need?Deciding what painting materials you will be needing for self-practice, art school or workshops can sometimes be more difficult than finding the creativity and inspiration to paint a subject. This can be exacerbated if you’re dealing with a tighter budget â€" however, there’s no need to stress. Anyone involved in artistic endeavors is no stranger to financial difficulty.The best way to start is first by picking the medium you would like to work with. This will enab le you to not only pick amongst the vast variety of watercolor, oil and acrylic paint, but it will also help you arrive to the art supply store with an estimate of what you’ll be spending.When buying paint, its always good to ask the instructor for advice on which paints are necessary and which are optional. However, as a general rule of thumb, a variety of five different colors, including white and black, is a good place for a beginner to start.Find painting classes in London.Canvases and brushes are a bit more difficult to shop for, as this will also depend on what your medium will be and what exactly you’ll be painting. We recommend getting a variety of three or four brushes all of different widths. Start with a small tipped detailing brush and make sure to include a flat, wide headed brush for the times you’ll want to paint on large swaths of paint.Canvas will be different if you’re painting with watercolor, acrylic or oil paint. The three most common canvases you’ll l ikely encounter are either sketchbooks, watercolor paper, or linen and cotton canvases. The canvas you’ll be using for practicing and sketching in paint will likely take the form of a sketchbook while producing bigger, more detailed pieces will necessitate larger canvases. Make sure to get whatever you think you’ll need in your class or workshop.Art Classes and Workshops in GlasgowStudying art in Glasgow can be a rich, and sometimes interactive experience. If you're on of the many young artists interested in pursuing an art degree, some of the top art universities in the world can be found in the UK.If you're simply looking for kids art workshops or adult art lessons, starting by looking online can facilitate finding an experienced instructor. Signing up for courses online with the Botanics Glasgow art center or sites like Superprof can help you find the right class or setting.Whether you're learning studio art or life drawing, plein air painting can be an option for people who can't pay for painting classes or simply prefer to self-learn at their own pace.

Amazing Physics Facts Fun Facts for Physics Appreciation ChaptersInteresting Physics Facts About Your PhoneCool Physics Facts About WaterPhysics Fun Facts About PeopleA lot of learners dread studying physics simply because it represents the marriage of two most-feared school subjects: maths and science.But, like every marriage, there are both lighthearted and more difficult aspects and, like most who make committed relationships work know, focusing on the lighter side is often what makes the darker times bearable.In that spirit, your Superprof now presents you awesome, amazing, cool, fun, neat and nifty facts of physics; aspects of this very serious science that make it so intriguing to so many.Hire a  Physics and Maths tutor S1  to help you appreciate science even more.Hopefully, by the end of this article, you too will be hooked!Nor can you tap to play your fav video with gloves on unless you have those special gloves that permit the conduit of ions through the knit.Another nifty physics fact related to phones: they make use of Einsteinâ €™s Theory of Special Relativity.GPS navigation depends on the very factors that comprise our most renown theoretical physicist’s superbly elegant formula: energy, mass and speed (time).Unnoticed by you, your phone is under constant scrutiny by a minimum of four precisely calibrated satellites that measure the distance you’ve travelled between exactly-timed signal pulses and apply your positioning on known maps.Look for the best Physics Maths tutor in Birmingham.You may well turn off your phone’s location services but your positioning data goes on regardless.Harvesting that data is one reason why Google is in such hot water just now!You may want to consult a physics glossary for some of these terms...Water slows the speed of light, meaning looking at anything through a glass of water will resort in distortion Source: Pixabay Credit: 95839Cool Physics Facts About WaterBeing as we just mentioned water, we’ll dive right into this life-sustaining substance to discover surface te nsion and light refraction.But first, a question: who doesn’t enjoy a refreshing gelatin dessert?Maybe not right now, when chill winds blow and winter storms threaten... let’s think back to summer when the heat was unbearable...Who among gelatin dessert lovers has not tapped their spoon on their treat, just to watch it wriggle but not yield?That phenomenon is called surface tension: when the outer surface of a body functions as an elastic membrane.The concept of surface tension is quite separate from flotation, which implies the object floating in the substance is more buoyant than the substance itself.Wood, for example, is much less dense than water, permitting it to float. However, should a tree branch floating in the river absorb enough water, it would become heavier and eventually sink.Gelatin has a relatively high surface tension, meaning you have to dig into your dessert rather than skimming across its surface, as you might with ice cream.Look up for  maths physics tutor   now.Water has the amazing property that, while being a cohesive body, each water molecule has surface tension!That is why, when you look through a glass of water, the image is distorted more so than if you looked through the glass alone.It has to do with water slowing down light: by the time it reaches your eye, you are not getting the whole picture.When light passes through water, its protons are only travelling at 3/4 speed.That doesn’t mean that classical physics is wrong: light does travel fast... under vacuum.If you filled the Large Hadron Collider with water and shot a beam of light through, it would travel much slower!Now, let’s talk about a body of water that has no more surface tension than any other, yet is denser than any on earth.The Dead Sea’s salt content is such that, although you can’t see the salt crystals swimming around in the water, they render that body so dense that an average human cannot sink!Which begs the question: why do drowning bodies sink and th en float back up to the surface?Find a  Physics Maths tutor  in London.The cause of drowning is taking water into the lungs, which makes the body heavier than the water. As the body decomposes, it fills with gas, making it lighter than water.What a gruesome idea!One last, most famous example of how water helped advance discovery: Archimedes and his bathtub.He was tasked with calculating whether crown makers had cheated the king by mixing silver with the gold the king had provided for his new crown, but he was not allowed to melt the crown in order to test its contents.Pondering the problem as he got in his bath, he noticed that the water level rose in exact proportion to his body’s volume. Thus, he reasoned he could submerge the crown in question, measure the water’s displacement and calculate the density of the crown.Gold is far denser a metal than silver, as you may know.So excited by his postulate was he that he completely forgot he was nearly in the bath â€" not a stitch of clothing on. He ran thus through the streets, shouting “Eureka!” - the ancient Greek equivalent of “I’ve got it!”Learn more about Archimedes' Principle, along with other key concepts in physics!We could be condensed to just elementary particles, meaning that all of humanity could be one very heavy lump of sugar! Source: Pixabay Credit: HumusakPhysics Fun Facts About PeopleAs a total science geek, crazy for anything to do with quantum mechanics or computational physics, I often bemoan the fact that I was born centuries too late to converse with Leonardo da Vinci, humanity’s most prolific polymath.But then, I am cheered by the fact that I lived in a time when Stephen Hawking was on earth and wonder if, centuries from now, would some soul get their introduction to physics through his Theory of Everything and bemoan the fact that s/he was born too late, too?That segment intro provides avenues to two fascinating areas of physics study: condensed matter physics and aspects of cosmology. Among others, black holes, dark matter and Hawking radiation.Did you know that the entire human race could be condensed into something the size of an ordinary sugar cube?We are all made up of atoms: protons, electrons and neutrons... and a whole bunch of empty space between them.If we were to remove that space in every human body, all of humanity would be as large as a cube of sugar, but it would be incredibly heavy because it would be extremely dense!That means that the theory behind the exploration of the quantum realm in Ant-Man and the Wasp is valid but the visuals aren’t: shrunken cars, buildings and people would be too heavy to pick up with just one hand.Space has the same space issue: what we can see comprises only about 5% of the whole universe.It’s not that we need better telescopes or equipment; it’s just that most of what the universe is made up of is space... filled with dark energy and dark matter.Perhaps that dark energy is what keeps virtual particles popping in and out of existence.Next time you pour yourself a glass of cola or other carbonated beverage, consider the life cycle of one bubble: it forms seemingly out of nothing, rises to the top and pops, releasing its tiny, gaseous load.The same thing happens in space, a phenomenon known as quantum foam. It stands accused of constantly breaking the laws of physics... but nobody knows why their doing so doesn’t affect other aspects of cosmological events or balance.And then, there are black holes.The general relativity theory predicts that a sufficiently compact mass, perhaps one with all of the space sucked out from its atoms as described above, can deform spacetime and cause such a gravitational pull that nothing, not even light, can escape it.The late, great investigator of cosmic phenomena, Stephen Hawking, not only postulated that black holes emit radiation but that they retain the trace memory of every cosmic event that falls into them.That concept is more famously expres sed by our favourite fictitious Doctor, who can see everything there ever was and everything that ever will be.A more real Doctor, Mr Hawking's last public engagement discussed gravitational waves resulting from the collision of two neutron stars, a boon for astrophysicists!You don’t have to be Sheldon, Leonard or Raj â€" or Stephen Hawking to appreciate theoretical physics and our universe, and you don’t need to be Howard to love the science behind statistical mathematics, electricity and magnetism.So much for actors playing physicists; how about real physicists and their discoveries?You only need to recognise that you are the embodiment pure physics: full of electricity and magnetism, with a dash of uncertainty principle thrown in.Now that you are comforted and enthused about physics, you only need to decide your undergraduate field of study:solid state physicsquantum electrodynamicsmathematical physicsnuclear physicsthermodynamicsapplied physicsparticle physicsAnd let us not forget the emerging role of women in physics!Ladies, you too can learn all about physics: how do experimental physics or quantum physics sound to you?

Online Proportion Definition Math Tutors

Online Proportion Definition Math Tutors Proportion in math is defined as the similarity while comparison between two quantities or substances. Proportion is also used between two geometric objects where the shapes, sizes, lengths can be compared. Proportion is a fixed ratio between two objects. Proportionality always maintains a fixed ratio between two fractions. For example, a / b = c / d. It can be written as a : b = c : d. Example 1: Find the x in the proportion 5 : x = 4 : 3. Solution: Here the given proportion is 5 : x = 4 : 3. It can be expressed as a fraction in the form. 5 / x = 4 / 3 Now multiply both sides of the equation by x. This gives 5 = 4 x /3. Now multiply both sides of the equation by 3. This gives 4 x = 15. Now divide both sides of the equation by 4. So x = 15 / 4. Hence the value of x for the given proportion = 15/4. Example 2: Find the x in the proportion x : 2 = 7 :4. Solution: Here the given proportion is x : 2 = 7 :4. It can be expressed as a fraction in the form. This gives, x / 2 = 7 / 4 Now multiply both sides of the equation by 2. This gives 2(x/ 2) = (7 / 4) (2). x = 7 / 2. Hence the value of x for the given proportion is= 7/2.
