What is pH? - Your Basic Knowledge on What pH Means

What is pH? - Your Basic Knowledge on What pH MeansAnswering the question, 'What is pH?' may seem like a bit of a daunting task at first, but when you consider that your basic kitchen equipment is composed of some four trillion tiny things called molecules, it's easier to explain what the term means. The molecules in your everyday life are hydrophilic (water-loving) and hydrophobic (water-hating). A water molecule is also known as a p-i-m-p and a hydrogen atom is also commonly known as H2O.In a water molecule is attached to one another by chemical bonds known as covalent bonds, which makes up all of the bonds between all of the other atoms in the body. The way in which a water molecule interacts with other molecules determines whether the water is in an alkaline environment or an acidic environment. The pH of a substance is defined as a number that indicates the neutral range in which an element is found.The pH of our body is usually between seven. When the pH level of our body is mo re acidic, our cells become acidic and when it is more alkaline, our cells become alkaline.The major influencers on our body pH level are the nutrients we ingest every day. As we get older, our digestive system no longer utilizes all of the nutrients contained in the foods we eat. The good news is that even though the pH of our body may change a little every day, it doesn't have to change drastically.One thing that can greatly affect the pH of our body is bathing in alkaline or acidic bath water. The primary cause of an acidic pH is a mineral deficiency such as iron or calcium deficiency. With our bodies being surrounded by so many minerals, we actually don't need to get nearly as much of these minerals from our diet as our diet does.Our body will continue to use our essential minerals just as much if not more than it needs the excess minerals we consume. Fortunately, our bodies can work to correct the imbalance if the nutrients we eat are replaced with the minerals our body needs. You won't be amazed at how quickly this can happen.The main focus of maintaining an alkaline pH is bathing in alkaline or acidic bath water. Baking soda is a great natural supplement for your body to counter the harmful effects of acidic water.

My Experience at Stanford University

My Experience at Stanford University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Michael is a San Francisco tutor specializing in Algebra tutoring, ACT prep tutoring, Writing tutoring, and many other subjects. He graduated from Stanford University in 2013 where he earned a Bachelors degree in Management Science Engineering. See what he had to say about his time at Stanford University: VT: Describe the campus setting and transportation options.How urban or safe is the campus?Are there buses or do you need a car/bike? Michael: The Stanford University campus is incredibly beautiful, from the tree-lined paths, to Lake Lagunita, to Palm Drivevery few universities can compare. Stanford Universitys campus is also incredibly safe, with very few crimes committed on a regular basis. It is very well lit, and there are safety beacons every quarter mile around the majority of the campus. While there is a free bus system that is relatively comprehensive, for the day-to-day commute from dorm to classroom, a bike is highly recommended. The campus is very bike-friendly, with bike racks outside every single building and classroom. It is also very car-unfriendly, and while parking is not that expensive, the time it will take you to drive to classes and park is non-trivial at best and much longer at worse. A car is useful to explore the surrounding suburbs, as apart from Caltrain, public transportation is minimal. VT: How available are the professors, academic advisers, and teaching assistants? Michael: The teaching community at Stanford University is top notch, and professors, advisers, and teaching assistants are readily available to help with anything and everything. From homework help to starting your own company, Stanford Universitys culture prides itself on being readily amenable to the student body and changes over time. However, you must actively seek those resources out. As a freshman, you will be initially guided toward them, but you must seek them out on your own accord if you truly desire them. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Michael: Stanford University students are characterized as being victims of the Duck Syndrome, which stands for someone who looks calm and collected on the surface and who will tell you everything is fine, while under the surface/water, they are paddling furiously to keep up with the demands of school. As a former Resident Assistant, this is entirely 100% true, and it can be a good thing in a certain way. Stanford University has such a wide variety of clubs, academics, and social functions that put demands on your time that the university will stretch you beyond what you have previously encountered. Problems arise when students take it too far, which tends to happen mostly during freshman year. The saying too much of a good thing is extremely applicable here. Dorm rooms are typically very well maintained, dining has some of the healthiest food options in the country, the location of the campus is incredible if you are interested in technology and Silicon Valley, and there are regular opportunities to interact with unbelievably talented peers. VT: Which majors/programs are best represented and supported?What did you study and why? Did the university do a good job supporting your particular area of study? Michael: I was a Management Science Engineering major, and the engineers at Stanford University are by far the best-supported students on campus. During my time at Stanford University, 2009-2013, that trend became even more pronounced as Computer Science and startup culture became central to the School of Engineering. There are incredible resources available for those interested in the humanities, but the schools natural focus has shifted toward engineers and startups. VT: 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? Michael: Your ability to meet individuals on campus through your dorm, as well as clubs, is limited only by the amount of time you have to go to those activities. As Stanford Universitys academic load is incredibly demanding, your time will need to be balanced accordingly. On the other side of the coin, students are typically incredibly open and welcoming to new individuals in whatever group they are in. I regularly joined new groups and organizations throughout my time at Stanford University. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Michael: Stanford University students are some of the most sought after students in almost any area of study, but particularly in engineering. While the Career Center can be helpful for basic questions, a large portion of the best opportunities come through the personal network that Stanford University allows you to develop. These can come naturally through your clubs/organizations that you join or pre-professional organizations that promote a certain career path. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Michael: The libraries have almost every possible book, movie, video game (yes, we have a video game archive), database, or magazine in the world, and if they do not, you can typically request it and have it delivered shortly thereafter. The Green Library (the main library at Stanford University) can get relatively crowded during finals periods, but you can always find a desk somewhere. Wireless Internet is plentiful and fast, and it covers the entire campus, so students are frequently seen studying (or not) out on the many acres of lawn around campus. VT: Describe the surrounding town. What kinds of outside establishments / things to do are there that make it fun, boring, or somewhere in between?To what extent do students go to the downtown area of the city versus staying near campus? Michael: The only downside to Stanford University is that Palo Alto, the town just off the campuss boundary lines, is not a great college town. Things are generally relatively expensive. However, the Marguerite and/or Caltrain can transport you to San Francisco or Mountain View where plenty of adventure awaits in under an hour. I would highly recommend exploring these areas if possible, and getting off campus if you can. Most students do not take advantage of this nearly enough. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Michael: Each undergraduate class is typically around 1,600 students, with about 7,000 undergraduates overall and approximately 9,000 graduate students across the many graduate schools Stanford University also has on campus. Introductory classes are typically large, often in the hundreds, but as soon as you hit sophomore year and you begin courses in your major, this number decreases dramatically. Discussion sections are also typically very small (about 10), which lowers the average class size. While some classes are large, I never felt as though it impeded my learning experience. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Michael: One of my favorite classes at Stanford University was one I took senior year that focused around venture capital and brought in speakers each week that discussed in detail one aspect of the industry. It was incredibly interesting, and it gave a fascinating perspective on an industry that I had been very interested in for a long time. It was relatively small and every student in the class was able to ask several questions each session. Check out Michaels tutoring profile.

Learn Spanish Grammar Intro to the Subjunctive Mood

Learn Spanish Grammar Intro to the Subjunctive Mood Sign up successful So, whats next once  you can communicate the basics comfortably and confidently? Advanced students who want to take their knowledge beyond basic communication can now begin learning about the Spanish subjunctive, usually taught in the third, fourth, or fifth  year in schools or universities. To speak Spanish well, knowing when to use the Spanish  subjunctive is indispensable. Why the Subjunctive is Important to Learn It’s ubiquitous in the language. Using it makes you sound like you really know how to speak Spanish competently. It enables you to tune into and express beautiful subtleties of the language that aren’t so clear or simply don’t exist in English. It allows you to express your point or opinion with more specificity. It has been referred to as a key indicator that distinguishes a fluent speaker who merely “gets by” learning the language from  one who speaks it well. You cannot speak as proficiently as native Spanish speakers without learning it. So, What is the Spanish Subjunctive? Although its commonly referred to as the subjunctive tense in Spanish, its actually more of a mood, which acts as a category of tenses. Youll know when to use Spanish subjunctive when youre trying to imply an uncertainty about a given situation (more on this below). Conjugating the Spanish Subjunctive Conjugating the subjunctive is  similar to forming  formal commands  in Spanish. The steps are outlined below: Additional Examples To clarify and provide a reference point, let’s compare subjunctive verb conjugation to present indicative (normal) verb conjugation. Here are some key examples: hablar (to talk) vivir (to live) Here’s another example with the  slightly irregular verb llegar, meaning ‘to arrive.’ Here the a  turns into  ue,  instead of just e. (See my previous post on Spanish stem-changing verbs to clarify this.) llegar (to arrive) When to Use  the Present Subjunctive Llegar  will be the example used throughout the following 10 key contexts for using the  present subjunctive. Context #1:  When the subordinate clause has elements that express doubt or negation Es difícil que lleguen a tiempo. (It’s hard for them to arrive on time.) No creo que lleguen a tiempo. (I don’t think they’ll arrive on time.) Dudo que lleguen a tiempo. (I doubt they’ll arrive on time.) Context #2:  When the subordinate clause has elements that express desire, fear, judgment, or other emotions/feelings Ojalá/espero que lleguen a tiempo. (I hope they arrive on time.) Temo que lleguen a tiempo. (I’m scared they will arrive on time.) Es triste que lleguen a tiempo. (It’s sad they arrive on time.) Estoy feliz de que lleguen a tiempo. (I’m happy they arrive on time.) ¡Qué bueno que lleguen a tiempo! (It’s good they arrive on time!) Quisiera que llegaran a tiempo. (I would like them to arrive on time.) Es raro/extraño que lleguen a tiempo. (It’s odd they arrive on time.) Context #3:  When the subordinate clause has elements that express possibility Es probable que lleguen a tiempo. (It’s probable they arrive on time.) Es posible que lleguen a tiempo. (It’s possible they arrive on time.) Quizá lleguen a tiempo. (Maybe they arrive on time.) Puede que lleguen a tiempo. (It could be that they arrive on time) Note:  Many competent Spanish-speakers don’t employ the subjunctive in these contexts to consciously or unconsciously communicate less doubt in the possibility. Context #4:  When the subordinate clause has elements that express need Es necesario que lleguen a tiempo. (It’s necessary they arrive on time.) Necesito que lleguen a tiempo. (I need them to arrive on time.) Es preciso que lleguen a tiempo. (It’s essential they arrive on time.) Context #5:  When the subordinate clause has elements that express an expected pattern Es normal que lleguen a tiempo. (It’s normal that they arrive on time.) Es lógico que lleguen a tiempo. (It’s logical that they arrive on time.) Es frecuente que lleguen a tiempo. (It’s frequent they arrive on time.) Es razonable que lleguen a tiempo. (It’s reasonable they arrive on time.) Context #6:  When the subordinate clause has elements that express specificity Quiero una novia que sea guapa. (I want a girlfriend who  is pretty.) Context #7:  When the subordinate clause refers to a past event before it occurred [past subjunctive] Ya supe eso antes de que viniera Juan. (I knew that before Juan arrived.) Context #8:  When the subordinate clause introduces depends on the main clause Eso depende de qué hora lleguen. (That depends on what time they arrive.) Context #9:  When the subordinate clause directly causes or affects the main clause El clima hace que no lleguen a tiempo. (The weather makes them not arrive on time.) El clima permite que lleguen a tiempo. (The weather allows them to arrive on time.) Context #10: In some cases, when the subordinate clause introduces a fact El hecho de que lleguen a tiempo significa que  son  punctual. (The fact that they arrive on time means they are punctual.) It’s important to note that there are other important contexts where the subjunctive mood is employed that I didn’t mention here. Also, the subjunctive follows a whole new set of rules in the past tense (i.e. the past subjunctive). My goal here was to highlight the most common contexts for using the present subjunctive. A Spanish tutor  can really help you master this tricky yet indispensable aspect of the language. If you’ve learned the Spanish subjunctive, you clearly know your Spanish! Post Author:  Jason N.

Use Summer Vacation to Boost Your Childs Academic Skills!

Use Summer Vacation to Boost Your Child's Academic Skills! Building Mathematical Skills For Academic Success As a parent it is difficult to watch your child struggle with math homework. The nightly routine of completing the assigned homework may lead to frustration, confusion, and feeling overwhelmed. Math shouldn't be the dreaded evening chore. Instead it should be an opportunity for your child to apply previous knowledge to current understanding while completing the assigned homework tasks.It is important to understand the core knowledge strands that comprise a student's mathematical learning. Whether your child is in second grade or a sophomore in high school these concepts are vital to mathematical understanding: Counting and Cardinality - Counting, cardinal numbers, comparing numbers, and understanding quantities Operations and Algebraic Thinking - Addition, subtraction, multiplication, division, use of multiple operations, relation of operations to one another, factors, multiples, numerical expressions, patterns, and relationships Number Operations in Base Ten - Place value, sequencing, place value in arithmetic, place value in fractions and decimals, and applying and understanding relational place value skills Fractions - Equivalence, ordering, building fractions, and arithmetic with fractions Measurement and Data - Understanding measurable attributes, classifying, measuring length, telling time, representing and interpreting data, estimating, counting money, applying geometric measurement principles, using probability to evaluate outcomes, and converting measurements Geometry - Identifying, analyzing, comparing, classifying, creating, and composing shapes with specific attributes, graphing points on a coordinate plane, understandingcongruence and similarity, and using geometrical understanding to solve real life problems Proportional Relationships - Ratios, analyzing proportional relationships, andapplying rate reasoning Expressions and Equations - Algebraicexpressions, reasoning with equations and inequalities, quantitativerelationships, variables, radicals, integer exponents, and linear equations Functions - Defining, evaluating, and comparing functions andmodeling quantity relationships Statistics and Probability - Statistical variability, distributions, randomsampling, comparative references, probability models, and bivariate data These skills are distributed among grade levels to provide a careful progression of skill attainment.

Both, Either or Neither Learn them in 3 Minutes (video + quiz)

Both, Either or Neither Learn them in 3 Minutes (video + quiz) I recently taught  a student that confused these three words. I didnt realize how confusing they  can be until I started explaining the mistake he made. It is confusing! They are all used in a similar way but can greatly change the significance of the sentence. Take this example:Are you Japanese or Korean?Neither, Im Thai.Actually I could be either. I was adopted and dont know my biological family.Both. My father is Korean and my mother is Japanese.Do you see how each of these changes the meaning of the sentence! Well, I have a video explaining the rules and there is a quiz to test yourself afterword. I hope this can clarify for you some of the confusion!Ready for the quiz? Click here!
