Stable Phase Definition Chemistry

Stable Phase Definition ChemistryThe Stable Phase Definition Chemistry is the job of The Cell and these persons are responsible for creating the life forms. It has been ascertained that from an elementary biology the synthesis of nucleic acids will be complex and life process will be characterized by the application of molecular dynamics and eventually crystallography.The Stable Phase Definition is an extraordinary chemical science which is not only a precursor of theoretical chemistry but also a contributor to structure formation. It can be said that the stables are the places where the molecules of the compounds stay unchanged and are the intermediates of the life process. The Stable Phase Definition Chemistry is the important role played by Ozone in the structure formation.Ozone, the main component of our atmosphere is responsible for transforming the atmosphere into the solid state. A normal concentration of Ozone is present at four parts per million and its activities are consta ntly dependent on the temperature of earth. The Ozone is a reaction which transforms the temperature and enhances the rate of electron transfer in the atoms. It makes the existence of oxygen molecules in the solid state.Stability are two main terms which are used in the stables as they describe the interaction between an atom and its environment. Ozone is an excellent compound which has the ability to produce stable bonds of hydrogen and other elements.When the Ozone interacts with the hydrogen atoms it becomes the gas and when it reacts with the oxygen atoms it produces the ozone. The Ozone has two atoms attached to each other and they are called oxygen and hydrogen atoms. The Oxygen atom is replaced by another atom and the final result is known as the hydroxyl.The balance of the Hydrogen atom between its two atoms is known as the equilibrium phase and the opposite is hydrogen bonding. Both of them are needed to create the structure. In equilibrium, the oxygen atom and the hydrogen atom are equivalent to each other and the molecule will remain in the solute state. The molecules remain in the stable phase until they reach a higher level of decomposition.When a molecule reaches the equilibrium phase there is a definite level of decomposition and a large proportion of the molecules will be in the hydroxyl and the hydrate state. The chemical properties of the hydrate are very similar to the hydroxyl, although they are less stable. The Reactive Oxygen has a certain affinity to the enzymes, proteins and protein complexes and it is believed that a large percentage of the oxidation will go into the reactive form.It can be concluded that the intermediate molecules are produced during the transformation of the compounds from the crystal to the final phase. In fact it is said that the structure formed by this substance consists of the group of hydrogen, ozone and stabilizer and the fact that this group represents the basic building blocks of life.

How Much Should You Pay For A Math Tutor?

How Much Should You Pay For A Math Tutor?The question of how much should you pay for a math tutor is actually a very difficult one. Depending on your math skill level and whether or not you will need to work with a tutor at all, the math tutor fees vary widely. These fees will vary according to the specific style of math tutoring that you are considering, but at the end of the day they will all be similar, as the rates will be determined by your needs and your ability to pay.Since math tutoring can range from completely free to a one-time fee of about a hundred dollars, it can be a challenge to find an appropriate math tutor for you. The best thing to do when you are looking for a math tutor is to research different tutors on a variety of websites. It is important to remember that the Internet can be deceiving in this regard, because there are certain websites which only tell you how to get a tutor. At the same time, there are also some websites that can provide the most basic inform ation you need in order to make a better decision about the math tutor.Before going out and looking for a math tutor, it is important to find out if the math tutor can help you at all. If the math tutor you are considering is only going to be teaching you a subject that he or she is familiar with, chances are that you are being given a worthless tutor and wasting your time.Most parents would be amazed at the number of private tutors that are offered. It is important to know the exact details of what you are paying for when it comes to your math tutor. If you have kids in high school, you will need to know how long you are going to be paying for the math tutor. This will allow you to know whether or not it is worth paying for a private tutor or if it is better to find a tutor that can teach you multiple subjects at once.If you are not willing to pay for a math tutor at all, there are some things that you can do to find out about math tutoring. First, ask your friends who they use for math tutoring. You may find out that their math tutor was very affordable and that their tutor has all the necessary knowledge that you need.After you have found a private math tutor who is right for you, keep in mind that your choice should be based on the person's experience and not his or her fee. Make sure that the tutor you are considering has a certificate from an organization such as the American Association of Private Tutors or AAPT. This will help you ensure that you are not getting a phony math tutor.Now that you know how much to pay for a math tutor, it is time to go out and find a math tutor. Remember that it is very important to research different tutors, as the Internet can be deceptive in this regard. Take your time, and do not rush into anything until you are absolutely certain that the math tutor you are considering has all the necessary skills and knowledge that you will need.

SIC Chemistry - What Is It And How Does It Help the Environment?

SIC Chemistry - What Is It And How Does It Help the Environment?First you need to understand that SIC chemistry is not all that different from the conventional ones we have been doing for years. We now use solvents, solvents and additives to make chemicals, but this is just a change in how the chemical is created.SIC chemistry is a science that is commonly used in the clean up of these chemical reactions. It is considered a 'clean up' because they are in it more than they actually were a time or a place. Some things will still get into our environment when we use the oil byproducts as the basis for their uses and in our daily lives.This makes us think about the future of clean up of this type of chemical and if it can be done, then it will certainly help in the environment. The most interesting thing about this is that if you would like to do some SIC chemistry yourself, the best way to go about it is to create your own products out of it. In doing so, you'll be able to release the c hemicals, but not be creating new compounds and reactions.After all, if you want to use this special type of cleaning on any sort of material and not have the harm that we are all becoming aware of with everyday use, you should think about this a bit more and realize there are ways to release these compounds into the environment as they come from the solid. You will need to take a little bit of work, but it can be very rewarding. I don't know about you, but I'm not all that impressed with some of the chemicals that are readily available in our supermarkets.The natural ingredients in SIC are nothing more than vegetable oils. These vegetable oils will actually form the basis of your cleaning products. You will need to mix them with other materials so that you can actually make something that does not contain hydrocarbons and they will not react with anything that is in the environment.I think that you will find these chemicals are not harmful, but if you do happen to find that there a re reactions going on, don't worry. Remember, SIC chemistry is completely safe. This will be great news for those of you who are trying to help the environment and clean up from the chemicals that are used every day.This is a very exciting thing to see, but don't forget that you also need to use it to clean up the oil deposits. The earth would be a better place if the other pollutants in our environment were taken care of.

WaitroseThe Top 5: A RoundupOther Suprisingly Good FindsMaking Your Own Vegan FoodLearn More About Vegan FoodThough you won’t find any mainstream supermarkets selling only vegan produce, you will find many popular UK stores offering a dedicated section or aisle specialising in nutritious vegan foods.Thanks to the increase in supply of vegan meals and individual ingredients, shopping for a plant based diet doesn’t have to be a struggle. And if your local shop doesn’t have a vegan food section, you might be pleased to hear that there a few hidden treasures among the better known brands that are safe for vegans.Some items aren't specifically targeted at vegans but are suitable for them to eat, like Ritz crackers, for example. Photo credit: JeepersMedia on Visual huntTake, for example, Ritz crackers, Kellogg’s (unfrosted) Pop-Tarts and Lindt Excellence Cocoa Bars. In 70%, 80% and 90%... so you might not hav e all of the ingredients to make a delicious, healthy vegan meal there but you can certainly find yourself a tasty treat to chew on! Plus, there are always healthy vegan options available such as lentils, quinoa, bananas, avocado and hummus available in most supermarkets if you don't have a sweet tooth.Take note of my top 5 list of supermarkets stocking vegan-friendly food options.Marks and Spencer offers its customers a good range of party food, suitable for vegans. Plus, they've released a brand new vegan and vegetarian range this past Autumn with thirteen products in it, just some of which are Sweetcorn and Chickpea Burgers, Beetroot Falafel and Sweet Potato Steak.Interestingly, they've also brought out exclusive plant-based soy proteins to replace chicken and beef mince: Veggie Chunks and Veggie Mince, which tastes delicious.MS has a relatively long list of dishes that are suitable for vegans which is updated each month for accuracy and consistency. They also pride themselves on their customer service and state on their website that a member of staff in store can help you find out what's available to you in that particular branch.What's more, it isn't just the shops that have vegan foods on offer, their numerous food halls are also full of delicious vegan options, labelled with the logo.3. Sainsbury’sSainsbury’s offer their customers a reasonable choice of vegan ingredients and dishes. Their Freefrom line offers vegan-labelled products, including vegan-friendly Turkish delights and ice creams. In their frozen section, you will find meat-free meatballs and burgers alongside Quorn and Linda McCartney products.If in doubt about which products are vegan or not, then use an Internet search to find out the vegan products shocked by Sainsbury's. Among the list, you will find a range of frozen goods that can be kept for months at a time (great for if you're running low on ideas for meals and inspiration for desserts), such as vegan pizza or vegetarian chilli, along with some household, beauty and health products, like Berocca energy vitamins and l'Oreal face cream.Also, as of November 2017, vegans can treat themselves to egg and dairy-free marshmallows, which come in pink and white, as well as a vegan whipped cream, which is said to go very well with a vegan hot chocolate!Learn more about cooking with these cooking classes.Vegans can find a suitable alternative to this pink and white treat in Sainsbury's. Photo on VisualHuntAs previously mentioned, Sainsbury's candy ranges are quite substantial. In addition to those mentioned above, customers can also purchase tangy sour snakes, cola bottles, raspberry liquorice and cranberry and orange fudge bites.4. TescoJust like its previous competitor, Tesco stocks an array of products suitable for a vegan diet, including cheeses, margarine, yoghurts, and ice cream. Their frozen foods section comprises of soya mince, kale and butternut squash roasts and falafels.If you have seen the collection of re cipe cards in Tesco stores, you may be wondering if the food giant also has recipes dedicated to vegans. The answer is yes.While they may not be available in card form at every shop, you can look at the Tesco Real Food pages online and discover a selection of vegan recipes, suitable for a quick mid-week meal or for a more relaxed dinner party at the weekend.Furthermore, Tesco announced earlier this year that it was releasing a new oven food range named 'Wicked Kitchen', which celebrates all that is 'Wicked' about plants. In collaboration with chef Derek Sarno, it has created irresistible, tasty and mighty flavoursome prepared meals for the vegan and vegetarian markets. This exciting development means that being vegan doesn't have to mean eating boring foods like whole grain rice, red lentil, quinoa salad and kale chips!Lunches in the range include Carrot Pastrami-Spiced Wrap, Sweet Potato Pakora Wrap, Rainbow Curry Salad Bowl and Moroccan-Inspired Bowl,  while meal options consist o f sourdough pizzas, burritos, noodles and mushroom bolognese.

WaitroseAs you might expect, Waitrose delivers the goods when it comes to a specific diet like veganism. Their extensive range of healthy vegan foods includes basil tofu, hotdogs, ice cream, curries, crisps and crumbles. Big name brands include Quorn and Cauldron.Waitrose's vegan section on its website is very easy to navigate, with se ctions to choose from ranging from Bakery to World Foods.As you would expect, the line includes fruit, vegetables, salads, seeds, nuts, plant proteins, frozen foods, and much more.Meanwhile, Waitrose announced late last year that it had teamed up with a vegan butcher in order to produce a brand new range of vegan products for its customers. This is as a result of plant-based foods being in such high demand. This partnership means that you can expect to see lots more of the recipes you have longed for, like interesting veggie burgers, a warming casserole, vegetarian chilli, spicy enchiladas, a rich vegan lasagna and maybe even a colourful vegetable curry. Who thinks that Waitrose, and the other shops in our top 5, should have a poll so that people can suggest some of their best ever best vegan meal ideas? Also, wouldn't it be nice if there were a meal delivery service close to you offering vegan lunches or meals?The Top 5: A RoundupHere is a roundup of the top five supermarkets for v egan food, and what makes them stand out from their competition.The Co-OperativeStocks vegan-labelled goods, including take-away style elements and alcoholMarks and SpencerOffers vegan-friendly confectionary, chocolate, ice cream and even has vegan lunches to goSainsbury'sHas a Freefrom line that includes a variety of vegan ingredients and meal alternativesTescoIncludes vegan cheese, yoghurts and ice cream as well as frozen items like mince meat alternatives, falafels and butternut squash roastsWaitroseStocks Quorn and Cauldron products plus an extensive range of vegan foodsOther Suprisingly Good FindsThey may not have made it into my (or The Vegan Society's) top five, however Morrisons, Aldi and Asda do offer some great vegan foods.While the high scorers featured above have specially-labelled lines for vegans, these brands seem to stock vegan goods more ‘by accident’, making them seem even more like hidden treasures!Granted, it is much easier to go to a shop's website and searc h for vegan items, but where's the fun in that?! Be prepared to spend a little while browsing and scrutinising labels but it well worth it when you find a gem of a treat tucked away in your local store, that many of your fellow vegans don't even know about. Just like vegetarian items though, most vegan foods will display the vegan mark on their packaging.Like vegetarian goods, vegan food is labelled with the 'V' symbol indicating whether it is suitable for vegans or veggies. Photo credit: Tony Webster on Visualhunt.comThe question is, will you spill the beans and announce to the world what you've found or will you keep it your little secret?Likewise, Lidl don’t have a great range of vegan foods but they do label their foods clearly and are cooperative when you ask them questions in store or by email.Making Your Own Vegan FoodOf course, you don't have to buy already prepared meals. You can make many food products yourself, using dairy, meat and egg alternatives to cook with. For ex ample, there are many ingredients suitable for vegans that can be used to make homemade vegan cheeses, mayonnaise and dips in place of the full fat alternatives.For a more extensive list of vegan food alternatives, read the blog What Is Vegan Food And Where Do I Get It?Furthermore, if you'd like to see some of the best vegan recipes out there, or find easy vegan recipes that won't be too challenging to cook, then why not take a look at some of my selected vegan and vegetarian recipes.

A Guide to Networking for the Socially Inept, Introverted and Reluctant - Introvert Whisperer

Introvert Whisperer / A Guide to Networking for the Socially Inept, Introverted and Reluctant - Introvert Whisperer A Guide to Networking for the Socially Inept, Introverted and Reluctant You know our type. We’re the kind of people who, for whatever reason, don’t really know how to start up a conversation. We’d rather hide under the table than start chatting with an unknown person, or stay at home watching reruns than go to a party. We’re your awkward cousin or the kid who sat behind you in biology. Is there networking hope for us? Yes. There is hope, and you’ll find comfort in knowing (for all of us procedural nerds) that it’s a process you can quickly and painlessly use. Like many things in my life, I’ve had to figure this out on my own, but I have followed it up with study. I know some people find it hard to believe I’m introverted since I’ve been known to speak to a crowd of a 1,000 people, but it’s true. It’s easier for me to do public speaking than make small talk. The difference is the type of talk and the setting when that talking takes place. As a speaker, I develop and deliver content with a specific goal in mind. It has a goal and a destination. I can research the topic and get prepared. For networking, all of that is out the door; you’re left by yourself to say something interesting. Egads! The difference is huge. Here are some things Ive learned about networking that really help if you’re an Introvert: What Is the Purpose of Networking? In the context of a job search, your network will be the number one way you’ll find a job. If you haven’t yet heard of the hidden job market, it’s the 80% of jobs businesses are hiring for that never get posted. The only way you’ll find out about them is if you connect with enough people who know what you do and how to connect you. Outside of the job search, you can think of your network as a vast web of information and connections. (Like this thought? Tweet it!) For your entire life, you’ve developed and nurtured your network. When you need a plumber, a doctor or a restaurant, you call your network. You learned as a small child that your network will share toys and sack lunches. We all have networks, but we oftentimes think of them as family, friends and work associates. Whatever you call them, you’ve developed enough of a relationship to call upon them for help and support throughout your life. Who Is Your Network? I could write one sentence here and be 100% accurate: Your network is everyone you know. Your network is the obvious people I mentioned above, but also clients, vendors, people you hire, the wait staff at Starbucks the list goes on. I should also add that you know something about these people. You may know limited things about them because of the place of business or setting in which you met them, but that is enough to get started. And now for the $64,000 question How Do You Get Past the Social Willies and Develop a Network? Think of networking as creating relationships with people. How do you create relationships with people? By getting to know them. You ask them questions about themselves! This was something I knew, but didn’t “know.” People think you’re a fabulous conversationalist if you ask questions about them. The more you ask others about what’s going on in their lives, the more you learn and can relate to them in the future. Let me give you a personal example. When my husband and I got married, my dad knew maybe four people at the reception. Yet for months afterward, people would tell me they had gotten to know my dad and thought he was great. Turns out he would approach someone and ask them, “How do you know Terry and What do you find to be the most challenging thing about networking? Share your thoughts in the comments!

Magnetism and Electromagnetism Everything You Need to Know.

Magnetism and Electromagnetism Everything You Need to Know. Your Guide to Magnetism, Electromagnetism, and Electromagnetic Induction. ChaptersWhat is Magnetism?What is an Electromagnet?What is Electromagnetic Induction?What is a Transformer?In the modern world, we use magnets in an overwhelming number of different ways. From the way that a fridge door closes to the way in which your headphones play music, from the generation and transmission of electricity, to the motor in your car. All of these use magnetic force in some way or another.Given the current ubiquitousness of magnets, our particular civilisation would be a bit useless without them. We’d have no way to move electric currents across the country. All of our electric motors would be useless. And we wouldn’t be able to talk across distance â€" as we have become so used to doing.As such, we shouldn’t take these particular things for granted. Rather, we should â€" all of us, that is, not just the scientists â€" try to understand what they are all about: how they work, what the special relationship is between electricity and magnetism, and how they make our world go around.This is our special task in this series of articles: to allow everyone to understand why it is that electrons have a magnetic moment, say â€" or why an electric current might produce a magnetic field. Why it is that magnetic flux can induce an electric charge, or why all of this stuff is so important for our world.Let’s take a look â€" from the basics of the magnetic field to the most important of the magnetic technologies.On Superprof, you can find a physics and maths tutor s1.

It is a ‘noncontact’ force that affects every single different object in the world, to a greater or less extent, and t hat is the result of the movement of these subatomic particles, electrons, and their electric charge.Electrons, Magnetic Moments, and the Three Types of Magnetism.Every atom in a substance is made up of particles, including the neutrons, electrons, and protons. In magnetism, it is the electrons that are doing the work.These tend to orbit the neutrons, and they each have their own charge â€" either positive or negative. What generally happens is that the electrons ‘pair’ with those of an opposite charge â€" meaning that an electron with a negative charge would pair with one that is positive â€" and so the material would be relatively stable, as each of the charges would cancel the other out.When substances have paired electrons, we refer to it as diamagnetism.However, there are plenty of types of materials â€" including oxygen â€" that have unpaired electrons. When this happens, the substance becomes much more magnetic, as the electrons can all align. In most of these materials, however, they do not, as the ‘magnetic moments’ of each of these individual electrons are not equal â€" unless they are under the influence of an external magnetic field.These substances which only demonstrate magnetism when they are in an external magnetic field we call paramagnetic.And, finally, there are the ferromagnetic substances. These are the magnetic materials which have unpaired electrons of the same magnetic moment. This means that, spontaneously, they can become magnetic â€" and they will remain magnetic even after the removal of an external magnetic field.What, then, is the Magnetic Field?Every magnet or magnetic object has a magnetic field â€" the neighbourhood around the magnet in which its magnetic force is present. It is the space affected by the magnet’s magnetic charge.Permanent magnets and electromagnets have enduring magnetic fields, which you will conventionally see with iron filings that arrange themselves into the shape of the magnetic field lines. Thes e will follow the flow from the magnet’s north pole to its south pole.Magnetic fields change depending on the strength of the magnet.Find out more about magnetic fields! What is an Electromagnet?Apart from the magnetic moments of the electrons, the other thing that produces magnetic fields are electric charges. This discovery, back in the 1830s, has been one of the most important in history, as it created the link between magnetism and electricity.We’ve just seen that electrons in a substance have a magnetic charge â€" due to the fact of their movement within the magnetic material.But the place in which electrons really move is in electric currents, which, really, are just the movement of electrons. As currents move down a wire, the wire becomes magnetized as the movement of the electrons produces the magnetic field.It was André-Marie Ampère who discovered this, as he showed that parallel wires would attract or repel each other, depending on which way the current would pass. (He would later give his name to the amp or ampere, by the way.)How to Make an Electromagnet.Since the very earliest electromagnets, the technology has not changed very much. They have become stronger, yes, but the overall structure of the devices has remained the same.Electromagnets are made of a coil of wire, wrapped around a core of metal (usually a ferromagnetic material like iron). Into the coil of wire is passed an electric current, whose magnetic field is centred into the hole in the coil â€" i.e. the iron core. This whole structure is known as a solenoid â€" and is still used in all of the places where electromagnetism is in action.As soon as the electric current is switched off, the solenoid ceases to be magnetic.A Note on the Relationship between Magnetism and Electricity.Whilst we know that electricity produces a magnetic field, and that magnetic fields rely on electrons, the distinction between a thing called magnetism and a separate thing called electricity is a false one.These are not discrete forces. Rather, they are the same physical principle â€" like two sides of the same coin. ‘Electromagnetism’ as a thing is actually one of the f undamental forces in the universe.You find out more about electromagnetism in our dedicated article.What is Electromagnetic Induction?One of the most useful discoveries in the history of electromagnetism was made by Michael Faraday, a British scientist in the nineteenth century. This became known as electromagnetic induction â€" and it remains one of the core parts of our knowledge of electromagnetism to this day.Faraday’s experiments focused on the way that electric charges can be manipulated by magnetic fields. And he surmised that changes to a magnetic field can be used to induce an electrical current.This sounds complicated, but his actual practical experiments were fairly simple. He took an iron ring and wrapped two different wires around opposite sides of the ring â€" producing two solenoids on the same piece of iron.Attaching one piece of wire to a battery, he attached another to a galvanometer, a machine which measures electric charges. Connecting and disconnecting the fir st wire from the battery produced a change in the charge detected by the galvanometer. This, for Faraday, proved that the change in the magnetic field in the iron ring could induce an electrical current on the separate wire.To prove his ideas about this particular relationship between electricity and magnetism, he did another experiment. Taking a solenoid without a core (so just a wire coil), he inserted a bar magnet in and out of the coil. Pushing the magnet faster, he found a larger current was produced in the wire.Why was this so important? Because Faraday paved the way for the knowledge that electrical currents don’t only flow through wire â€" whilst he set the theoretical ground on which we came to produce electrical energy by manipulating its magnetic field.Learn more about electromagnetic induction! A diagram of a magnetic fieldWhat is a Transformer?Transformers are the crucial piece of technology that use the science of electromagnetic induction.They are perhaps the most common electrical devices on the planet, with almost the entirety of electrical energy that we produce and use passing through at least one transformer in its journey.So, what are transformers? A transformer is a static device that changes a current of a high voltage into one of a much lower voltage. It does this through the presence of two adjacent solenoids and through Faraday’s electromagnetic induction.Across the country, electricity is transmitted through massive electrical networks. But to keep costs down, the electricity that is transported is of super high voltages. This â€" rather than a high current â€" reduces wasted energy and means that the wires themselves don’t need to be big.However, we can’t actually use high voltage electricity. So, before the electricity is distributed locally into our homes, it needs to be transformed into lower voltage electricity. That’s what transformers are for.Reducing Current Voltage.Faraday’s law shows how electromagnetic induction can be used to reduced and increase the voltage of electrical currents.Think back to his experiment: he used two different coils, in which the changes in magnetic field between the two induced an electrical current in the second.If, however, you vary the number of coils in the wire, you can change the voltage of the current induced. Say you have ten coils on the first wire, you can simply halve the number of coils on the second and you have half the voltage.This is precisely how transformers work.

Over the past few years, this popular freelance site went through a major growth spurt going from 200,000 in the year 2012 to over 300,000 in 2013. So, how can you get in on this profitable fun? Below are some tips for you to follow when thinking about getting into the freelance writing business. Persistence Pays Off The writer who is persistent is the writer who eventually gets there in the end. If you have a great deal of talent, but are unable to handle rejection, freelance writing might not be for you. Rejection is just a part of the overall scheme of writing. A writer, who hasnt received a rejection at one point or another, is most likely a writer who has no work published. In other words, even the most talented, professional writer gets rejections. Passion for Writing This might seem obvious, but its important to keep in mind that being a freelance writer, your job will be to write every day. Having a passion for writing or more specifically the niche you are writing in is important and will make the fluidity of your work easier. Some things to consider: Make your writing original Polish up your grammar skills Have the ability to express yourself with clarity and ease Believe in Yourself Before applying to be a freelance writer, sit down and ask yourself if you actually believe you can do it. Do you have what it takes to be successful in freelance writing? If you believe in yourself, then you should move forward. If you answered no to these questions, however, this could ultimately step in your way of succeeding. Basically, you want to help yourself in freelance writing not hinder yourself. When you lack belief in yourself, it is apparent to your clients as well. But, if you exude confidence, your clients perception of you and your abilities will be heightened. A Job or Hobby Last, and most important, it is up to you to determine whether your writing is going to be a job or a hobby. Sure, many writers do it for fun. They enjoy writing about what they love. Most, however, are trying to earn a living with it. This is the ultimate decision for you to make. If you decide you want it to be your job, you will need to step up to the plate and work it like a full time job. This doesnt mean you cant still have fun with it.

A Student Perspective on University of Houston

A Student Perspective on University of Houston Melissa earned her bachelors degree in political science from University of Houston in 2012. Subjects she specializes in include Spanish tutoring, math tutoring, and reading tutoring. Below she shared her experience with student life at University of Houston: Describe the campus setting and transportation options. Melissa: The campus is just southeast of downtown Houston, right next to an up and coming neighborhood called EaDo (east end downtown). Houston itself is rich in culture, diversity, and plenty of exciting things to do. The campus reflects this and they have plenty of events ongoing through the year, run both by the campus and student groups. They just built a new football stadium a few years ago, so campus pride is at an all-time high. I always felt safe on campus, there were a few incidents that happened throughout my years, but security on campus was pretty quick to respond and they were always around. The campus itself has shuttles, but most buildings within your major will be concentrated in one location. The campus has a city light rail station that runs next to it and can easily take your downtown. The bus system is pretty vast, due to the fact that Houston is a very spread out city. However, it is not known for being the quickest. Your best bet would be to get a car or bike to travel around Houston. How available are the professors, academic advisers, and teaching assistants? Melissa: All the people I had on campus were very welcoming and willing to work with me. All you have to do is ask! How would you describe the dorm liferooms, dining options, location, socialization opportunities with other students? Melissa: The University of Houston (UH) has a student body that consists mainly of commuters. However, if you decide to live on campus, there are plenty of things to do in the evenings. The campus is located next to a few major attractions/landmarks, so there is always something to do. The campus also has expansive food options. Which majors/programs are best represented and supported? Melissa: The best known programs are the creative writing doctoral program, Bauer business, architecture, law, optometry, and pharmacy schools. All majors and programs are well supported by the university. I decided major in Political Science, with a minor in world culture and languages (German concentration). UH did an excellent job providing opportunities for people within my major, like offering internships through a program called the Civic Houston Internship Program (CHIP). CHIP connected us with local government offices and organizations to help us get field experience as well as establish career connections. I also did a study abroad and they have an office dedicated to helping us with information and departure. How easy or difficult was it for you to meet people and make friends as a freshman? Does Greek life play a significant role in the campus social life? Melissa: I did not attend UH as a freshman, I came in as a transfer. However, they had enough activities at the beginning of each semester that made my arrival very welcoming. It also gave me a chance to meet with people and join clubs. There is Greek life; however it does not play a huge role there and does not feel overwhelming. They do help out with major events. How helpful is the Career Centerand other student support services? Melissa: The career center is actually a hidden gem. They offer a wide variety of services such as how to boost your resume and mock interviews. They also run a job board that many reputable companies use. There are some job fairs that take place throughout the year and many major companies recruit, but I did not attend any. How are the various study areas such aslibraries, the student union, and dorm lounges? Melissa: The MD Anderson library is 8 stories tall, with plenty of open space, conference, and study rooms. There are plenty of quiet rooms if you dont want any distractions (the joke is the higher up you go, the less people you will run into). The library has great weekday and weekend hours, and they even open 24 hours during finals week. They just built a new student center which is really big and has a lot of space. There is also a smaller student center located on the south side of campus if you want to grab a coffee or quick bite to eat. It is kind of underground, but there are a lot of spaces inside and outside to sit and relax (or study). Describe the surrounding town. Melissa: UH is located in Houston, not too far from major local attractions. As the fourth largest city in the U.S., there is always something exciting to do. The campus also has a venue that hosts major comedians and musical acts from time to time. Houston is rich in diversity and culture, any type of food or drink you crave, you can certainly find there. The city has some dedicated green spaces that host a lot of free events throughout the year, such as concerts, fitness, and there is almost always a cultural festival going on. Downtown Houston is where most business is conducted, but the neighborhoods around downtown are the places to go. There, you can find world-class restaurants, art galleries, and any cultural thing you can think of. The campus is located in a residential neighborhood, but it is close enough to plenty major attractions. How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Melissa: UH is a huge campus. There are an estimated 40,000 students, so during the semester the campus is really bustling with activity. The only classes I had that were more than 100 students were my introductory classes where students needed a certain credit. However, the professors in those classes or the TAs were readily available. For the rest of the higher level classes I had, there were no more than 25 or 30 students per class. I was very pleased with the class sizes because as long as you put in the effort of scheduling a time with a professor or took advantage of their office hours, they were always willing to meet. Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Melissa: I had one professor, Professor Jackson, who seemed intimidating at first. He was a former prosecutor and very sharp. Over time, I learned that he was extremely nice and would always make the effort of helping students that were looking for it. It took me until my second introductory to law class with him to finally approach him for help. Be sure to always ask for help. The right university will always offer some sort of help, and UH had a wide variety of resources available to its students, sometimes you just had to do a bit of digging. Take a weekend to see what your university offers; you may be surprised at how much support they have available! Check out Melissas tutoring profile.
