However, many students find that their education is greatly enhanced by taking the following two courses - Chemistry and Physics. You can choose from a wide range of subjects to study at Baylor.For those who prefer to study in the day, you could take a good chemistry course. This might include a course in the area of theoretical chemistry or organic chemistry. Students might also choose a pre-professional level course, which involves working in a lab environment for up to one year, at an accelerated pace. If you are planning on applying to the police force, this is the best way to prepare for it.Classes are taught in a classroom setting with three or four professors teaching a class. There are usually lab sessions throughout the day where students can work under the supervision of the instru ctor and receive assistance from his or her assistant. Generally, there are no special programs offered by the school and all of the materials are available from the library.Depending on your specific area of study, there are special courses offered by Baylor. For example, there are courses that help students with electives from biology, biochemistry, physical sciences, mathematics, and engineering, to name a few. If you like to travel and attend conferences, it is best to consider this school if you are planning on attending these events.If you are enrolled in courses that require laboratory work, such as Biochemistry, Chemistry, Physics, or Organic Chemistry, you will find that there are requirements that you must meet before you are allowed to join a lab session. The first step is to register with a lab coordinator. It is a good idea to go to the registrar's office and speak with them to determine what your responsibilities are. You will be required to fill out a registration for m, pay the application fee, and provide the lab assistants with your contact information and the instructors' contact information.You should also check with the instructors and see what coursework they expect you to complete before your students work in the lab.

The coursework can range from simple classes to highly complex topics, depending on your interests.

Tesla-tested, Hepburn-approved 8 Springboards to Learning Languages Used by Famous Polyglots

Tesla-tested, Hepburn-approved 8 Springboards to Learning Languages Used by Famous Polyglots Tesla-tested, Hepburn-approved: 8 Springboards to Learning Languages Used by Famous Polyglots Ever wonder why so many people in the U.S. never manage to learn a foreign language?You might say the state of foreign language teaching  has something to do with it.You might also consider aspects of geography, politics and social issues.These are all connected and related to the problem, but theyre not the real root reason.We learn languages when we  need them to get by.This is why people in non-English-speaking countries actually have an advantage  when it comes to language learning.At some point, theres a good chance theyre going to want to speak English, whether for travel or business or school. When youre traveling in some foreign land and you give someone that I have no idea what you just said face, whats the  second language  they try? English.That leaves some English speakers asking, Why bother to learn a new language when everyone already speaks mine?Even if you have a real desire to learn languages, your lack of a practical, everyday reason to learn one might make progress ing difficult.But there are some  inherently good reasons for anyone to learn a foreign language. These are reasons that many famous people have grasped and used to their advantage to become figures of historical importance.Lets take a look at the lives of some influential  polyglots and their life projects that led them to learn languages.Youve probably heard of most of these people, but likely didnt know some of them were polyglots. Thats because being polyglots wasnt how they got famous. For them, language learning was a means to an end. And that was very likely part of the reason for their success.If we take a cue from their lives, we might just be able to find those motivating factors that can raise people to such language learning heights that they achieve that seemingly unattainable status of polyglot. Tesla-tested, Hepburn-approved: 8 Springboards to Learning Languages Used by Famous Polyglots1. Electrify Your Career Like TeslaFamous for his work with electromagnetic field s, Nikola Tesla was also a well-developed polyglot,  speaking a total of 8 languages.  His language learning wasnt just an idle pastime, however. Tesla was born in modern Croatia and studied science in what is now Austria and the Czech Republic before moving to the United States to work for Thomas Edison.Think about that. A guy from a place thats still little-known, at least by Americans, was hired by one of the foremost inventors in America at the time.So take a page from Tesla and tie your career ambitions to learning a new language. With todays job market being as unpredictable as it is, following his example couldnt be a better idea.2. Start a Language-based Project Like WebsterYou probably know his name from the Merriam-Webster dictionary, but Noah Websters ambitions were much grander than many people now realize. At a time when everything from spelling to pronunciation varied wildly across America, Webster wanted to standardize the language and give people a common language.In his drive to assess the etymology of the words he was selecting for his dictionary, Webster managed to learn more than  20 languages. Wow! What was his secret? Besides possibly some flashcards, maybe not much more than the desire to complete his project.In short, to really get yourself motivated you should invest in a project involving language.  Pick something related to what youre already learning. If you study religion, try to translate a text relevant to your research. If youre into film, try to subtitle some little-known foreign film that you think deserves more publicity.If youre not sure what might interest you, consider  FluentU, an online immersion platform that takes real-world foreign language videosâ€"like music videos, movie trailers, news and inspiring talksâ€"and turns them into personalized language learning lessons.With material that suits a wide range of interests and tastes, FluentU  lets you discover whats meaningful to you about the language youre learning whil e also providing daily motivation to practice it.3. Get Political Like Ho Chi MinhWhatever political reservations those in the West might have about him, Ho Chi Minh was to many Vietnamese their George Washington. He fought decade after decade for his countrys liberation from colonialism and in the process  he learned at least 5 languages, including English, French, Chinese and Russian.Theres nothing like political fervor to spur language development.What lesson can we take from Ho Chi Minh then? Go out there and organize! Try to find a political cause that you have strong feelings about and is intrinsically connected to a second language. For example, in the U.S., an obvious issue would be immigration and organizing recent Hispanic immigrants for voting.4. Do Good Like HepburnYou may know her as one of the most famous actresses of all time, appearing in such films as Breakfast at Tiffanys and My Fair Lady, but Audrey Hepburn was also an ardent humanitarian. In fact, she was present ed with the Presidential Medal of Freedom by George H.W. Bush for her work.What made her such a great aid worker? By now Im sure you see it coming. She spoke at least 5 different languages in addition to English.To follow in her footsteps, then, try reading up a little on humanitarian organizations, like NGOs or the Peace Corps. See what kind of work they do and get inspired. Once youve dedicated yourself to a worthy cause, learning a language will seem much more necessary, and necessity means quick learning.5. Buff Up Your Language Like MiltonIf theres a specific area of literature people dislike, its usually poetry. Hopefully you were never forced to read John Miltons infamously lengthy Paradise Lost against your will.But no matter what your views on Literature-with-a-capital-L are, Milton is someone to respect. He created 630 new words for the English language, all with the help of his knowledge of 8 different languages.Aspiring writers today are all over the place, and if you ar e one, you know its as hard as ever to stand out. Why not learn from Miltons success and use language learning as a tool to create inventive prose? At the very least, youll be unique.6. Deliver a Message Like Pope John Paul IIAn extremely popular Pope and one just as well-traveled, Pope John Paul II visited 129 countries  during his tenure. But he didnt simply visit these countries. From his desire to spread his ideal of an alliance between the major religions sprang a secondary desire to learn to speak the tongues of these countries. In total, he learned to speak 8 languages.Like Pope John Paul II, perhaps you already have a message that you hold dear to your heart and think the people of the world should hear. How better to spread a message than saying it in words people can understand?And while it may seem to be a bit presumptuous that you could be as influential as the Pope, no one says you have to be him. Change can be effected by everyday people, each one doing their part. Aft er all, if it wasnt for the ordinary missionary, the one who tramps out into the places that most civilized people would never dare go,  it seems unlikely that Christianity would have spread to such far flung corners of the world.7. Get on the Cutting Edge Like EngelsAre you an engineer? Or perhaps a researcher in a science field? Whatever you may be, theres undoubtedly an international intellectual community waiting for you just beyond the reach of the English language.To see how well learning new languages can connect you to an international community of fellow thinkers, we might look to Friedrich Engels. Yes, that Friedrich Engels. The one who co-wrote The Communist Manifesto with Karl Marx.Ideology aside, Engels was an extremely effective communicator of his ideas. He reportedly spoke many languages and wrote his correspondence to co-conspirators in the language of their origin. Its hard to doubt that this international communication helped him to develop into the influential th inker that we know today.If you aspire to be a great originator in your field of choice, learning some extra languages could go a long way.For example, if we look at the field of medicine, it is clear that what gets studied is directed by our cultural biases. In much of the Western world, for example, there is a disdain for folk medicine.A country like Japan, on the other hand, has maintained a deeper respect for its traditional medicine and as a result has conducted more scientific studies on the viability of such medicine in the present day. Thus, by learning another languageâ€"like Japaneseâ€"you could tap into an area of research that remains constricted in the English-speaking world.8. Go All-out for World Peace Like ZamenhofOkay, okay. So you probably dont know this guy. But you should! Ludwig Zamenhof was the inventor of Esperanto, now the most widely spoken artificial language. Esperanto, for those who dont know, is a sort of simplified and universal European language. If yo u already know a European language, you should be able to read and understand it without much extra knowledge.What gave him the expertise and knowledge to build such a language? Mastery of at least 9 other languages.Zamenhof built Esperanto for one reason. He wanted to make it easier for people to understand each other and thereby foster world peace. After all, think of all the times when a peace process would have been made impossible without a mutual knowledge of foreign languages.Maybe you dont need to make an entirely new language (there are quite a few of those already), but why not set out to foster world peace?Anything from teaching English for a couple of years to underprivileged kids to becoming a professional diplomat dedicated to mutual understanding could make a significant difference in the lives of many people.  And once youre giving it your all for world peace, learning those nine languages will seem like childs play.If youve been wondering in amazement every time you ve heard the word polyglot, unable to imagine the superior beings who could acquire such skills, think of these people. Sure, theyre famous, but none of them set out specifically to learn new languages. They did so because they had things they wanted to accomplish that necessitated learning new languages.They  needed new languages.Thats the kind of mindset we should all have.

Chemistry Styles in Football - How Does Chemistry Styles Work?

Chemistry Styles in Football - How Does Chemistry Styles Work?Just what is the difference between football and soccer and how do chemistry styles work in these sports? What is the method of building up or boosting the performance of a team and how can chemistry play a part in this?Football and soccer are both very popular games and are played worldwide. The object of each game is to win and this is done by collecting more points than your opponent. A point is the basic unit of football and is worth a point when awarded and in soccer is worth a goal, assist or a goal.Soccer is played with the ball on a flat surface that is divided into 18 squares called 'squares'. The sides of the square are known as 'fields' and there are 3 teams in the game that include the goalkeeper and the forwards. In football the game is broken down into four sectors where the ball is placed and there are different formations for each team.While in soccer the players use their own skills and techniques, in foot ball the players need to be able to combine their skills and techniques in order to win the game. So far as soccer is concerned, it can be said that it is more competitive than football as the rules are very strict and most players do not like to lose.Chemistry Styles in Football: There are two ways that chemistry can be used to boost the performance of a team. Firstly, it can be incorporated into the strategy plan. The second way in which chemistry can be used is through the performances of the team. It is in this manner that football is regarded as being more skill based than soccer and therefore football can be classified as a more skill-oriented sport.There are many teams who go into competition as a team rather than individually. This gives them the advantage of playing together to win the game. This also makes the game faster and hence quicker to play. The third factor is that the players who do the best work together so they make the most of their ability together.Football fa ns will appreciate chemistry Styles in Football teams will benefit from a good game plan and an excellent performance from their players. This will be a vital part of winning a football match as the players must work together in order to win the game. So if you are interested in football then it is advisable that you try to learn how to create a team that works well together.

How to Solve Linear Equations

How to Solve Linear Equations If two linear mathematical expressions are connected and related by the sign of equality, an equation is formed. An equation satisfied for some particular value or values of the unknown quantity or quantities. The unknown quantity of an equation is called variable. For example: - a x + b = c x + d An equation containing one of the highest power of the unknown quantity is called a linear equation or first- degree equation. a x + b = 0, a 0 is an example of linear equation. How to solve a linear equation: - Question 1: - Solve the linear equation 2 x + 4 = 8 and find the value of x. Solution: -Step 1: - Try to keep all the variables on L.H.S. and constant on R.H.S. Constant 4 is there on L.H.S., so we can subtract 4 from both sides to remove 4 from L.H.S., and then we get 2 x = 8 4 2 x = 4 Step 2: - Try to free the coefficients from the variable. So we will divide both sides by 2 so that coefficient of 2 will be remove from both sides. 2 x / 2 = 4 / 2 x = 2 Therefore x = 2 Question 2: - 6 x 3 = 9, find x. Solution: -6 x 3 = 9 6 x = 9 + 3 6 x = 12 x = 12 / 6 x = 2

How To Play Bluegrass Guitar Common Fingerstyle Techniques

How To Play Bluegrass Guitar Common Fingerstyle Techniques Sign up successful Three-Finger Style Otherwise known as the Scruggs Style after banjo player Earl Scruggs who first popularized it, this fingerstyle employs a thumb pick, index finger pick, and middle finger pick to pluck individual strings on the guitar. The advantage over other picking styles is the speed at which experienced players can play arpeggios and string skipping runs without breaking rhythm. This gives the guitar a very percussive, lively sound that lends itself well to an ensemble setting. However, this isnt to say that players using this technique can only play single-note runs. Many experiment with combining this style with strumming via thumb pick or either finger pick. As always, you are free to play whatever you like! Three-finger style is versatile and popular but can be difficult for players with limited fingerstyle experience. When learning this style, try picking individual chord tones with a slow, consistent rhythm before speeding up as you are able. Using a metronome will greatly increase the effectiveness of these exercises because it will keep you honest! If you keep falling behind the beat, just turn it down and start slower. This kind of practice is the quickest way to become an amazing picker. Three-Finger Style Techniques Because many bluegrass fiddle tunes are in the key of C major, I have presented these exercises using C, F, and G chords to portray typical chord progressions. When you are learning how to play bluegrass guitar, it is wise to stick to a simple set of chords. It’s how you use them that matters. Three-String Runs The idea here is to use your thumb for the bass notes and your two fingers for the two high strings in each measure. If you pull it off, you can keep the rhythm strong with your thumb while filling out notes with your fingers. Try different chord tones to find the voicing that you like. Four-String Runs This exercise is almost identical the one above, except that the thumb is utilized not only for bass notes but also for a high string as well. Experienced bluegrass players learn to play in this style for the fastest of the fast songs. Make sure to start slow with that metronome! Two-Finger Style This variation of the Scruggs Style was favored by bluegrass guitar legend Lester Flatt. It omits the middle finger pick in favor of a simple thumb pick and index finger pick combination. Because of this simplicity, the two-finger style is easily adopted for purposes that resemble flat picking. The main idea is to use the thumb to pluck individual bass notes while strumming with the index finger. This is great for playing loud chords in a driving manner and is often used to carry the main harmony of the song. In addition, this style can be used to simulate bass lines in the absence of a bass player. But just like with Scruggs style, you are free to explore and find more ways to utilize this approach to playing bluegrass guitar. Here are some exercises I would recommend to become acquainted with the two-finger style. And don’t forget your metronome! Two-Finger Style Techniques Again, these figures are portrayed in C major for simplicity but you are not stuck here. Playing around with different chords will give you a better idea of what you and your guitar are capable of. Pluck-and-Strum This exercise is all about getting you acquainted with the capabilities of two-finger style. Specifically, it is about using your thumb to pluck the bass note of each chord before strumming two full chords with your index figure. Bluegrass ballads often call for this type of guitar arrangement. Fast Strum Now we’re getting to the fun part. Some bluegrass tunes are played at extremely fast tempos, and by speeding up the pluck-and-strum you just may manage to keep up. The key here is to play the chords almost as if you were flat picking with a normal guitar pick. The difference is that you can still use your thumb for the bass in two-finger style, but you will still most likely resort to strumming both up and down with your index finger. There’s no diagram for this one find a fast bluegrass song to play along to and try to keep up! (I usually use the song “Wait So Long” by Trampled By Turtles when I teach). Keep Practicing Some of these techniques may seem tricky at first, but don’t be discouraged. Practice at least ten minutes a day for two weeks and you’ll be seeing some serious improvement! No bluegrass guitarist ever became great overnight, and with these common fingerstyle techniques you now have a roadmap for how to get there.

Electromagnets and Electromagnetism.

Electromagnets and Electromagnetism. What is an Electromagnet, and How Does it Work? ChaptersWhen Did We Discover the Electromagnet?Recap: What is Magnetism?What is Electromagnetism?How Do Electromagnets Work?What Do We Use Electromagnets for?An interesting question to pose would be the following: what would the world be like if we didn’t have electromagnets?Whilst magnets themselves â€" and the magnetic field in general â€" are naturally occurring phenomena, electromagnets really aren’t. They had to be invented. And, given that these things combine an electric current with a magnetic material, they arrived in our lives actually relatively late in the history of things.Electromagnets are some of the most powerful magnets we have. And, because of this, they have become absolutely crucial to industry, technology, and all sorts of different everyday things that we have about our homes.And so, learning about electromagnets is not just wild, irrelevant theory, no. Rather, they are hugely useful â€" and can do things that only they can actually do. Not to mention the f act that the science of the electromagnet is pretty fascinating in itself.So back to that question: where would we be these days without the power of the electromagnet? The answer, honestly, is nowhere very much at all. We’d have no generators â€" and no possibility of power storage and power transmission â€" for example.But we’ll come back to that question later. Let’s take a little look at the theory of the electromagnet.Looking for a physics and maths tutor s1? Find one now on Superprof.

It was Hans Christian Ørsted (or Oersted) who first realised that an electrical current creates a magnetic field, whilst Sturgeon made the first, rudimentary, electromagnet.However, no-one knew quite how this coil of copper wire could produce a magnetic field for another century, almost, when in 1906 a French physicist started to tackle the problem. And with his theory of the magnetic domain, we came a step closer to knowing what on earth was actually happening in the middle of all that coiled wire.But this story mi sses two of the most important names in the history of electromagnetism. You might have heard of Michael Faraday â€" who discovered the principle of electromagnetic induction. Or of André-Marie Ampère, who showed that two parallel wires repel and attract each other depending on which way the current passes â€" and who gave his name to the amp (or ampere).Electromagnetism has, since then, been a technology that has gone from strength to strength, filling our world with things that we don’t even realise have such an importance.Let’s take a look at the science.Recap: What is Magnetism?The science of electromagnetism is based on the object of the magnet and all its related phenomena: the magnetic poles, magnetic force, and the charged particles which animate all this at a subatomic level.But do you remember what magnetism is precisely? We discuss it in detail in our article, What is Magnetism?, yet it is helpful to have a little recap here.Magnetism works because of unpaired elect rons. Whilst electrons are the particles that make up part of the atom, most materials have electron pairs with opposite charges. These charges are known as ‘spins’ and are conventionally known as ‘positive charge’ and ‘negative’.When electrons are paired, their respective magnetic moment is neutralised â€" meaning they have no magnetic force.However, when they are unpaired, they are not neutralised â€" and in properly magnetic materials, scientifically known as ferromagnetic materials, these electrons can all spontaneously point in the same direction, giving the material properly magnetic properties.This ferromagnetism is found in materials like iron and nickel. Electromagnets produce a strong magnetic field.

The discoveries of the likes of Ampère, Faraday, and Ørsted lay in precisely the realisation that this wasn’t the only way in which magnetism worked.Rather, they saw that electrical current flow also has a magnetic field. Ampère’s discovery â€" that wires with currents flowing in opposite directions attract each other â€" proved this.In electromagnetism, the whole of the wire through which the electricity is flowing becomes magnetized. This, again, is due to the electrons. But rather than just directed in a certain way â€" or arranged ‘inline’ â€" in an electric current the electrons are untethered from their atoms and flow along the length of the material. This provides the magnetic strength.Fundamental Interactions.However, electromagnetism â€" this combination of magnetism and electricity â€" is quite a lot more important than just the electromagnet itself.In fact, electromagnetism is actually described as one of the fundamental interactions that motivates all physical laws (the others being gravitation, weak, and strong interactions). And so electromagnetism is actually the force that keeps atoms together, it is responsible for light, and it is responsible for the bonding of chemical compounds.It is really a very busy thing, electromagnetism. And its discovery â€" as well as our ability to harness its power â€" has been a hugely important part of human’s scientific development.Find out about magnetism and electromagnetism here!How Do Electromagnets Work?But how do these things work, these electromagnets precisely? We’ve heard enough about the background, but how does an electromagnet per se function.An electromagnet works in pretty much the same way as a simple bar magnet. It has, like such a normal permanent magnet, a north pole and a south pole, which tend to reject the identical poles of other magnets. Again, in the same way, it produces a magnetic field â€" the same that you would be able to see with iron filings.However, the difference between an electromagnet and a normal one is that an electromagnet has a much stronger magnetic field. And, of course, you can turn it off and on by switching off the current. Both of these things make it part icularly useful.The Structure of an Electromagnet.As we discussed above, the physical reason for the magnetic force differs between a normal ferromagnet and its electromagnetic cousin. In the former, the electrons are aligned â€" yet, in the latter, the current of electrons that is electricity produces the magnetic field.So, wires themselves are magnetic, as Ampère showed. But to make an electromagnet, we use a more sophisticated method.This method is based on coils of wire. Take a cylindrical piece of ferromagnetic metal such as iron and wrap the wire coiling â€" usually made of copper â€" around it. As soon as you switch the electricity on, the current will run through the wire and will magnetize the metal in the centre â€" just like a permanent magnet.Switch the electricity off and the metal will cease to be magnetic.It’s that simple really. And you don’t strictly need the iron core â€" as the magnetic field that coil produces is already centred on the hole through the middl e of the coil. However, that iron core, or ‘magnetic core’, makes the electromagnet even more powerful â€" thousands of times more powerful.You could make an electromagnet yourself, if you wanted to. But be careful â€" and do it under supervision.What Do We Use Electromagnets for?So, let’s return to that question, what would the world be like these days if we didn’t have electromagnets? It really is a fascinating question â€" and we could perhaps phrase it better as what things wouldn’t we have if we didn’t have electromagnets?The answer is potentially quite long. But we can answer this question with reference to some of the most powerful and ubiquitous technologies that use electromagnetism. They are honestly everywhere. These things are all using magnetic fields.Electric Motors and Generators.An electric motor â€" that you’ll find in cars and all sorts of other machines â€" relies on the interaction of a magnetic field with an electrical current.These are made from a stator â€" a magnet around the edge of the motor that remains static â€" and a rotor, a rotating electromagnet that is almost identical to the coil described above.As electricity is put into the coil, the coil becomes attracted to the stator, which is then flipped so that it repels it. Consequently, the coil continually spins and produces mechanical energy.These, motors, by the way, are in everything from your computer to your headphones, your oven to your hard drive.Generators are identical, mechanically; they just work in the opposite direction.Transformers.Given that electrical power lines carry hundreds of thousands of electrical volts, before that electricity enters your toaster (which only needs some two hundred volts), it needs to be reduced in voltage. That’s what a transformer does.It works through the placement of two coils. That huge electrical voltage passes through the first coil. If you put a coil with fewer turns in it alongside it, the electrical current will jump across to the next coil â€" but will have a lower voltage.Without this thing, you wouldn’t be able to use any electrical equipment in your house.Magnetic Levitation.One of the coolest things people have done with electromagnets is magnetic levitation, or maglev. This is a transport system in which trains levitate â€" and can go faster more efficiently due to the lack of friction.This requires to sets of very strong magnets. One lifts the train from the rails and the other propels it done the track. Some sophisticated trains now use magnetism to avoid friction.
