What Is Colloids in Chemistry?

What Is Colloids in Chemistry?What is Colloids in Chemistry? Colloids are simply any of a group of substances that consist of microscopic particles like salt, mineral, or rock that are suspended in a liquid.There are three basic types of colloids in chemistry. The first type of colloid is the granular form and includes inorganic materials like calcium carbonate, bicarbonate, etc. The second is the inorganic colloid is composed of molecules with an atomic weight below the hydrocarbon number. This is the substance that is commonly used to stop oil from bubbling out of your engine when you put your car in a drive-by and then lose your tail.The third form of colloid is the polymer colloid which is a mixture of solid particles and a liquid. The solid particles are usually water or glucose.Colloids can be made from liquids or gasses. Hydrogen is the most common as it is the least dense of all the four elements and its crystalline state makes it relatively easy to form colloids. Some colloi ds can also form by the dissociation of small molecules that are made up of carbon, hydrogen, nitrogen, oxygen, phosphorus, etc.The many different types of colloids in chemistry also vary in their molecular weights. The most common by far is sodium chloride. Calcium and magnesium are also big colloids in chemistry because they contain large numbers of carbon atoms, whereas carbon, hydrogen, and oxygen can be easily broken down by enzymes in the body. In some colloids like vitamin C, you may get enough as the acid and base states to sustain your body functions.Colloids in chemistry can play several roles. A big one is that of a humectant. Humectants attract moisture to a surface so that it doesn't evaporate, but rather stays on the surface.Colloids in chemistry can also serve as catalysts and add resiliency. The activity of colloids in chemistry can be exploited to provide more or less certain chemical reactions can be produced more quickly and efficiently by using a larger amount of colloids.

8 ways to make new connections while teaching abroad

8 ways to make new connections while teaching abroad One of the most intimidating parts of teaching abroad is the thought of going it alone. Even if you’re an extrovert, striking out on your own is scary and the thought that you don’t know who’ll you’ll be celebrating your next birthday with or even simply hanging out with on the weekends can feel downright weird. But on the flipside, the friendships you make abroad can be some of the most enriching and rewarding aspects of your time there. You’ll meet people you never expected, from places you’ve never been to and expand your social network wider than you ever imagined. Sounds magical, doesn’t it? So, where do you begin? Use your existing network You never know who has friends or family in the place you’re moving to. Maybe your cousin has a friend in Beijing or your colleague has a brother in Sao Paulo. Making new connections from established ones is great because you already have a bit of a connection to the person you’ll meet, and a recommendation from someone you already know and like. So, ask around or write a status update on your social media, and see who find you! Get to know your colleagues When you arrive in your new home, get to know your colleagues. Some of them might not be from overseas, but even if they’re not, they’ll definitely be able to give you useful insights into what it’s like to live in this country. Make sure you say yes to any work social events and if there aren’t any, why not try organizing one yourself? Or you can schedule individual coffee dates with your colleagues to try and get to know them better one on one. Get out there IRL If you want to meet people you have to be around, well... people! A good place to start is by exploring your local neighborhood. Say hi to your neighbors, find places you like going to and become a regular face there, and you could even check out your local library for community events. Beyond this, say yes to any invitations that come your way. It might feel weird turning up to things alone, or taking up opportunities that wouldn’t normally interest you, but you never know where you might meet someone interesting. One of the first things to do is to enter new places with a positive, can-do attitude. Follow your interests If you’ve ever wanted to volunteer, join a sports league or take up a new hobby, now’s the time to do it! You’ll meet new people with similar interests, get to know more about the place where you live and follow your passions all in one go. If you’re not into joining groups, try going to events that look interesting to you. Anyone you meet there obviously shares your interest, so kicking off a conversation with a stranger won’t be too difficult. Tap into the expat community In most cases, there are sure to be other expats in your new home who understand just how it feels to move abroad on your own and is open to starting friendships. Bars and restaurants based on a particular culture can be a great place to meet people from your home culture. You can even find online groups detected Rethink your living space Next up, your living space might not seem like a hotspot for making connections, but let’s look into it. When you first arrive in a new place, how about staying in a hostel while you’re looking for permanent accommodation Sure, people in hostels can pass through pretty quickly, but you might meet others in the same position as you or get along with the staff, or find the hostel has great social spaces that you can come back and hang out in even after you find a permanent place to live. Living in a share house can also a great way to meet people, especially locals. Once you get to know your housemates, you can get to know their friends too, and before you know it, you’ve got the makings of a community. Connect online Lastly, finding social groups online can be a great way to connect with people IRL in your new home. Searching for expat groups or groups based on mutual interests on Meet-up, Facebook and even Instagram can be a great way to get in touch with people. And there are plenty of groups (like Teach Away’s Community!) out there too where you can share tips and advice about moving abroad and make new connections. Attend events hosted by your embassy If you are working somewhere that has a strong relationship with your home country, then it is likely that your home country will have a robust embassy and cultural presence there. What does this mean for you? Well, embassies and cultural centers will host events that celebrate their nation or bring together expats and are open to the public. These events can range from film screenings, food festivals, concerts, seminars and more. It’s a great way to ease your homesickness and find people who speak your language or know your traditions. Find your embassy or cultural center, and on their website and/or social media pages, you will see their upcoming events posted. A final few tips: Keep an open mind. When you're overseas, you’ll meet people from different cultures with completely different worldviews to your own. Keep an open mind when you meet new people that you don’t understand straight away, as they might end up teaching you more than you expect. Keep going. Not everyone you meet is going to be your new BFF, and you might have to sit through a few awkward coffee dates before you find people you truly connect with. Accept that making new friends will take time and keep putting yourself out there. You never know who you’ll meet next. Take the initiative. If you meet someone you click with, ask for their number and follow up with them. Simple, right? This might feel super awkward at first, but ultimately you’re paying someone a huge compliment by saying you want to keep in touch with them. Who wouldn’t be flattered? Be patient. Even when you meet someone you click with, it can take time to go from acquaintances to friends. Invest time in people and give friendships space to progress at their own pace. Remember, everyone feels scared about going it alone when they move abroad. But with a little time and effort, you absolutely will create friendships that last through your overseas adventure, andâ€"who knows?â€"maybe long into the future.

3 Facepalmingly Simple Ways to Avoid Failing at Language Learning

3 Facepalmingly Simple Ways to Avoid Failing at Language Learning 3 Facepalmingly Simple Ways to Avoid Failing at Language Learning How can something so simple burst into flames?I mean, everyone knows at least one languageâ€"and plenty of people learn them successfullyâ€"and yet you feel like you just cant make it happen.Learning a new language  is often a confusing process.We look ahead and see a long, winding road without any signs or direction.We often don’t know how to get started, nor do we have tons of  time to commit to learning.This leads us to waste our energy, money and, most importantly, time.That stops today. We’re going to show you the some of the most deadly mistakes nearly all language learners makeâ€"and how you can avoid them all.By the end, youll have overcome all the major hurdles to starting a language learning venture and maintaining your progress in the long term. 3 Facepalmingly Simple Ways to Avoid Failing at Language Learning1. Identify your “why”Understanding your “why” is where it all has to start. As Simon Sinek explains in his book, Start with Why, the reason why you’r e doing something is far more important than what it is or  how you do it.This is because whenever we take on a new task or project, there’s always going to be an obstacle or struggle that we’ll need to overcome. Its always fun to try something novel, but then well need to step up our game and work harder to get better at it. Those who  give up early on are the ones who  haven’t clarified what their “why” is.Let’s come back to language learning. Whatever your target language isâ€"Spanish, Italian, Korean, etc.â€"what’s your “why”?Here are some questions we recommend you ask yourself:What will I achieve?Who will I  be able to connect with?What is the most exciting  thing I will be able to do?Who will I  become as a person?The next time you’re facing difficulty or losing motivation, just come back to these reasons, and you’ll get right back on track.2. Set clear goalsAccording to Tony Robbins, the motivation man, “setting goals is the first step in turning the invisible into the visible.”It doesn’t matter if we have the fastest car in the world. If we don’t know where we’re going, we’ll just end up wasting precious energy, money and time going nowhere.All of us have a desire that we want to fulfill, we just have to clarify what that is, and make it the driver to our success.There are the  key components to setting goals. Your goal has to be:Visually specific â€"  Get as visually clear as possible about what your end result would look like, to the point you can close your eyes and imagine it. Where will you be speaking your new language? Will you be making friends while  sipping fruity drinks on a beach in Latin America? Will you be chatting while watching movies in Seoul? Or do you see yourself connecting online  with native speakers?Slightly out of reach â€"  There is a fine balance between  picking a goal that’s way out of reach and one that is easily within reach. This goal should be something you can visually imagine, but a goal that you would need to push yourself to accomplish. For example, you might not be able to tackle a French novel tomorrow, but with time and practice you totally could! Measurable â€"  What doesn’t get measured, doesn’t get improved. The easiest way to do this is to put a number on it. This could be number of words memorized, the length of conversation you can have with a native speaker, etc. Results-oriented?  â€" Focus on the results, not how much time you spent getting to them. For example, instead of measuring how many hours you studied every week, only measure what measurable result you achieved. Its okay to take your time reaching the goal. Remember, it doesn’t matter how much effort you put in unless you don’t get the results from the effort. Deadline-specific â€" As Parkinson’s Law  states, the time we spend completing a task will depend on the time we allocate to the task. This means that if we give ourselves 30 days to complete a report that should only tak e 30 minutes, that’s exactly how long we’ll take to complete it.  Whatever goal you set, make sure you have a realistic deadline to accomplish it.Let me share three examples of goals that are bad, good and great, so you can get an understanding of how your goals compare.Bad goal: I want to become fluent in Spanish so I can travel to Spain  someday.Good goal: I want to become conversationally fluent in Spanish so I can travel to Spain by next summer.Great goal: I will have a 30-minute conversation in Spanish with a native Spanish speaker over coffee in a cafe in Madrid in July 2016.Do you notice the difference?Compared to the first two goals, the great goal is written as if it’s already accomplished (I want versus I will) and includes all the components of the goal-setting formula including deadlines as well as being measurable, visually specific and results-oriented.3. Make a scheduleThe most successful people and top-performers in their industry focus on the process, not jus t the deadline. Optimal performance is less important than the daily practice of taking action, no matter how hard it is or how tired you are.If you want to write a book, this could mean waking up each morning in order to write 500 words, no matter how bad the first draft is.If you want to double your business sales, this could mean spending every week with your team reviewing your sales numbers and executing a new growth experiment.If you want to lose 10 pounds, this could mean running 30 minutes every morning.For many of us, learning a new language is not the #1 priority in our lives. It’s our family time and careers that take up our focus.This is why scheduling your learning time is even more important than scheduling your work time.Here are some practical steps we recommend to schedule your learning time:Pick your language learning activity  â€" This could be memorizing 30 of the most common words on your own, working with a private language coach or learning with a FluentU vi deo.Figure out your free times? â€" When are the vacant times you have during the day?  If you’re a morning person, it could be before work. It could be during lunch break or at night once the kids are in bed. It could even be on your commute!Add in 15 to 30 minutes of buffer time? â€" Schedules never go according to plan. This is why we want to make sure we add some buffer time, so if we happen to wake up later than usual, or get held up in  traffic on the way back from home, we can still use the buffer time to stay on track.Set reminders  â€" Because we probably have a dozen things we need to remember during our day, setting notification reminders goes a long way.  This could be done through any digital calendar software you use (i.e. Google, Outlook, etc.) and you can even get set up to receive them on your phone.Find someone to join to the journey  â€" Ever heard the saying, “if you want to go fast, go alone. If you want to go far, go together”? It’s easy to resort to go ing at it alone. This is how we’ve lived most of our lives.  But if you observe the best performers and the fastest learners, they have someone who works with them, whether it’s a mentor, advisor or coach.That last point is a key one.In almost any aspect of our lives, we have a coach that we work with, whether it’s a fitness trainer, financial advisor, business mentor or sports coach. This is the best-kept secret amongst the best performers and the fastest learners in the world.Language learning is no different.If you’ve truly discovered your why and have a clear goal that you’ve set for yourself, you should find moving forward a breeze. Then it’s time to get outside help, to guide you through each step of the way, keep you accountable and accelerate your learning speed.Anyone can learn a new language, no matter how old you are, how busy you are, and even if you’ve tried before with limited success.It’s all about finding the right strategy that works for you and, of course, avoiding the most deadly mistakes that language learners make.

Everything about Thales the Mathematician

Everything about Thales the Mathematician From Thales' Theorems to His Discoveries ChaptersThales of Miletus: The Life of the MathematicianHow Thales Influenced Math CoursesThales From Math to AstronomyThales in the Context of the GreatsMathematics is a subject that often comes up in debates about the education sector, where it is repeatedly one of the subjects that school children struggle the most in. It is considered to be an essential step in the academic career of students, where students are expected to consolidate their knowledge every year in order to to be successful and understand new mathematical notions.What is involved in the framework and what is at the origin of this discipline? Cosines, reciprocals, fractions, quadrilaterals, relative numbers, circumferences, symmetry, tangents, inequalities â€" revising over courses in mathematics can become less stressful when viewing it through the lens of history.

The latter, a professor of the former according to historical texts, was a philosopher born in Miletus around 625 BCE. Aptly named, the Greek philosopher Thale s of Miletus is considered as one of the seven sages of ancient Greece, along with other Greek philosophers: Solon, Chilon of Sparta, Pittacus of Mytilene, Bias of Priene, Cleobulus of Lindos and Periander of Corinth.Founder of the school of Milesians, Thales started off his academic career as a philosopher and scientist by going to Egypt at a very young age, thanks to good relations that existed between the country and his maternal city, Miletus. It was there that a young Thales discovered the knowledge of Egyptian and Babylonian sciences.Once there, he learned geometry, astronomy, and philosophy â€" all knowledge that was a core part of the educational training of Egyptian priests. This trip to Egypt is not really supported by data, according to ancient Greek historians. In fact, only some records written years after the death of Thales have been able to attest to the life of the scientist and place him in Egypt at the time.Once he reached adulthood, Thales returned to the Greek c ity of Miletus to create the School of Milesians. Thales used his position to spread his knowledge in mathematics and Greek philosophy, all the while continuing to perform observations and scientific experiments.Throughout his life, Thales used his observation in order to discover how the world functioned. According to the legend, he calculated the height of the great pyramid, helped predict a lunar and solar eclipse and put into practice the theorems of Thales.Check for a reputable maths tutor near me here.Ancient Greece, and especially Miletus, had a deep influence on Western philosophyHis mathematical and scientific research are considered as having revolutionized the times.Considered as a sage, Thales always prided himself on explaining his discoveries from a rational point of view instead of a mythological one, las was tradition at the time. For him, the process of observation and creating proofs were the base of scientific reasoning.According to some accounts written many year s after his death, Thales died around 547 BCE in Miletus while attending a gymnastic competition. Found in the bleachers, he had apparently died of hunger, thirst and age.Some other great mathematicians and philosophers from this area include Archimedes!How Thales Influenced Math CoursesEveryone has heard of, and even learned, many of the theorems that Thales discovered. Thales was the first to mark the history of mathematics in the creation of his scientific formula and principle. Here are five of the geometric theorems he has been credited with:A circle is bisected by a diameterAngles in a triangle are equal if their opposites are two sides of equal lengthIntersecting straight lines produce opposite angles that are equalA right angle, and its corresponding right triangle, can be drawn inside of and using a semicircleIf a triangle’s base and two angles are given, the triangle can be drawnWhile these may sound too simple today to have ever been considered revolutionary, they actua lly give us a lot of information and were considered a major innovation at the time. Thales’ theorems are utilized to calculate certain relationships of longitude and proportions in geometric figures possessing parallel lines. They are also used to calculate many concepts in trigonometry, when there is the presence of two parallel lines.According to legend, Thales discovered this theorems while calculating the height of a pyramid. To do this, the mathematician calculated the shadow of the pyramid to the floor. With the help of a cane, Thales was able to calculate the dimensions of the pyramid of Egypt in relation to the shadow of his cane.While Thales is credited with these theorems, however, they were already known by the Babylonians and Egyptians. We know this most notably thanks to the proof elaborated in the book Euclid’s Elements, which deals with the proportionality of areas of triangles of equal height. However, Thales was credited with putting words to the latter.Thales does not receive credit in many countries for some of his theorems. For example, the English call one of his theorems the Theorem of Interception, while for the same theorem the Germans call it the Theorem of Rays. However, these are all not completely identical and it resembles more the theory of Pythagoras.The history of Greek mathematicians is incomplete without the mention of ThalesThales From Math to AstronomyDuring the course of his life, Thales utilized mathematics to understand important notions of real life. Math exercises, prime numbers, decimals, equations, medians, subtraction, addition, philosophy, architecture â€" math served as a tool to understand the world around him.Early on in his career, Thales developed a passion for astronomy and analyzing the sky. Because of this he is considered as one of the pioneering forces behind of Greek astronomy.Similar to his research in mathematics, Thales utilized the method of observation for constellations in order to understand h ow the universe functioned. He made many discoveries in these areas:Used the little dipper to guide sailors in the open oceanCalculated the length of a year thanks to intervals of a solstice and equinoxesIndicated the pathway of the son in between the two tropicsListed the ephemerisHis discoveries were only a small part of his observations. Most notably, he analyzed the number of days in a year and concluded that the year is not 365 days but 365 days and a quarter. This discovery would later be the the base of leap years.Thales also observed stars in movement, the diameter of the sun and the moon â€" all the while using the same system of measuring objects relative to the shadow of a cane. He also located the position of Pleiades, calculated the orbital inclination of zodiac, etc.Thanks to his observations, Thales also could have predicted a large harvest of olives according to Aristotle. He applied these observations of nature in order to explain how the world functioned, but most often simply ended up ameliorating the lives of those around him. For example, sailors learned how to orientate themselves thanks to him and navigation advanced tenfold.Astronomy and all of its associated fields owe a lot to Thales, who was not but a simple mathematician. To learn more about how these discoveries influenced the work of another great mathematician, Rene Descartes, click here!Thales in the Context of the GreatsAll of Thales’ discovers have placed a special mark on the field of mathematics. Arithmetic, complex functions, whole numbers, polygons, multiplication, factorization, probability - his knowledge and discoveries are still taught in our day and in our maths courses, which is what places Thales as one of the biggest mathematicians of history.Ancient philosophy was impacted by thinkers like ThalesHowever, more than his discoveries, Thales theorized knowledge that was already established by the Egyptians or Babylonians. The mathematician didn’t just content hims elf with this knowledge, laid out in mythological truths, but searched to observe and prove all these affirmations that he encountered during his studies through math. In this way, Thales baffled his contemporaries.In a book by Jean Voilquin, the scientific French editor explained that Thales wanted to “replace mythological explanation” of phenomena “by physical explanation.” This is what leads Voilquin, along with many others, to name him as “one of the precursors to Greek science.”Thales’ scientific legacy is magnified by the discoveries made by his School of Miletus. Called the Milesian school, or “Ionian School”, their work revolutionized the field of science and they have come to be known as pre-Socratic philosophers. His teaching, specific to Thales, favored visual perception and observation in order to inject practicality into knowledge.The school included mostly geometry and astronomy, Thales’ two preferred fields, but it also worked on subjects like biol ogy, physics, and metaphysics. They were the first students to be called Physics-ians and studied everything about nature.The Miletus School disciples utilized concepts like the four elements in order to give explanations over the function of the environment. All these studies are considered as the first scientific investigations into nature and have left an indelible contribution to the sciences.Thales didn’t just mark the field of mathematics in antiquity, but also the history of science   as a whole, inspiring works of even Sir Isaac Newton. For that, we should remember his name along with his achievements.
