Chemistry in Nature

Chemistry in NatureHow many of us are aware that chemistry in nature is the foundation for any form of our modern technology? The study of chemistry has been practiced since ancient times and the discovery of fire can be traced back to Egyptian times. We cannot take this for granted today. There is an age old rule known as the first law of thermodynamics, which says that anything that becomes less efficient in a process, will become less useful.Our world, with its complexity and abundance of plants and animals, is very much dependent on the work of chemical reactions. Without them, the Earth would cease to be a place where complex life flourishes. Chemicals, and with the help of chemistry, we have been able to create useful structures. Chemical reactions that give rise to the elements we live in our bodies were originally catalyzed by chemicals. These were brought about by the reaction of light with certain types of compounds.Origins of chemical reactions have always been closely gua rded secrets. The originators of the first man-made molecules remained highly guarded. Modern chemists have in many cases only recently discovered these origins and therefore there is some question in the minds of the general public about their true identities. This fact does not mean that the answers are not important or they are anything but important.Some well-known pioneers of modern chemistry have gone on record in saying that they believe that modern chemistry owes a lot to the work of synthetic chemistry. Synthetic chemistry is the science of creating new compounds that look just like the ones that exist naturally, and in turn giving the human race the ability to use these natural materials in a variety of ways. It is through the chemical processes of synthetic chemistry that we have acquired some of the tools that we use every day such as, plastics, detergents, drugs, pesticides, lubricants, cosmetics, food additives, and many more.Many of the first crude attempts to perform chemical reactions on one or two or three of these substances failed miserably. In order to understand the entire problem, we must begin with the fact that our bodies are not the same as the earth's or the planet's. The molecules in the body are much smaller, making them difficult to bring about reaction. The key to a successful chemistry experiment is to use one of the very few chemicals that can easily cross the first laws of thermodynamics.It is possible for one or two of these materials to cross the first laws and successfully complete the chemical reaction. The things that make these substances work, is that they are very lightweight and very big, which makes them very stable, but at the same time gives them the ability to move very fast. If the material we are attempting to study does not contain enough oxygen, it will keep moving very slowly through the chemical process. In addition, if we are looking at a substance with even the slightest possibility of being found in natur e, then we should start with the highest level of purity that we can find, and then we move down the chain from there.Scientists are still working out the exact relationships between different types of chemical reactions, but it seems quite likely that they will agree that chemistry in nature is a vital part of the equation. The ones that do the research to know the answer and they are going to publish it.

What is it Like to Attend Arizona State University

What is it Like to Attend Arizona State University The tutors behind Varsity Tutors are not just here to teach theyre sharing their college experiences as well. Jeffrey is a Philadelphia tutor who specializes in Chemistry tutoring, Algebra tutoring, AP Biology tutoring, and much more. He graduated from Arizona State University in 2011 with a Bachelors degree in Psychology. Check out his review of his alma mater: 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? Jeffrey: The Tempe campus is a beautiful suburban campus right off of Tempe Town Lake. Though hot during the summer, most first-year students rely on walking/biking/skateboarding around campus. Older students and commuters typically live off campus within driving range. Some bus routes and more useful light rail routes provide decent mass transit options to and from the campus and even to the downtown campus. Campus safety is pretty well maintained with only some minor theft incidences and rare assaults every year both on campus and nearby off-campus areas. VT: How available are the professors, academic advisers, and teaching assistants? Jeffrey: Faculty and staff availability varies widely depending on programs and classes. I had many wonderful professors and TAs who had great office hours and went above and beyond to help every student who needed it. I also had professors who barley seemed to realize that teaching involved interactions with students at all. Advisers and staff varied greatly as well. Big programs like Psychology and Biology involved well in advance scheduling in order to get any face time with an adviser and usually the meetings seemed rushed. Though that isnt to say I didnt get some great advice and help when I really needed it and knew where/who to go to. VT: How would you describe the dorm life rooms, dining options, location, socialization opportunities with other students? Jeffrey: I spent all four years of my time at ASU living in the dorms both as a resident and as an RA (CAs at ASU). The rooms run the range of roomy, comfy, and huge, to tiny, musty, and prison-like. Of course, the nice, new dorms (Hassayampa, Barrett Honors Dorms) are extremely expensive, while the not so desirable dorms (anything in North campus) are more reasonable. The dining options are overpriced and a bit forced. During my time there, I never fully enjoyed the dining hall options, with the possible exception of the new Barrett Hall dining which of course cost more. The good news is they offer options that allow you to largely avoid the dinning halls and instead buy food from the Markets and various campus restaurants. Socialization is hard to avoid as there are countless clubs, communities, and activities going on seemingly every hour of every day. Needless to say, you shouldnt have any trouble making friends and having fun on campus. 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? Jeffrey: The Business School gets all the love, mostly due to President Crows bias and plentiful support from private sources. ASU also had decent support for its successful Nursing and Broadcasting Schools. I was in the College of Liberal Arts and Sciences (CLAS) majoring in Psychology with a Biochemistry minor. I came into ASU wanting to study the brain, hence the Psych major, and then realized I wanted a bit more science in my life and picked up the Biochemistry minor. The Psychology department was huge and well-run, as were the Biochemistry/Chemistry departments. Chemistry support for students was amazing with many study aids, TAs, tutors, and just about anything else one could need to pass scary classes like O-Chem, P-Chem, and Biochem. The Biology department to a lesser extent had decent support. Though I have heard the Bio department has improved since I graduated. 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? Jeffrey: Social life was almost too easy at ASU. Apart from the typical social atmosphere cultivated within the dorms, the campus is flush with many events geared toward having fun and meeting new people. Of course, there are also the unsponsored social events that naturally go on both on and off campus throughout the week. Football games are also, in my opinion, the best way to socialize. Greek life has, and Im sure always will have, some role at ASU. Though many steps have been taken by various people both within and outside of the school administration to drastically limit the negative effects that have come with our Greek life history. This includes both completely kicking out all of the on-campus fraternity houses and stricter enforcement of fraternity suspensions. VT: How helpful is the Career Centerand other student support services?Do many reputable companies recruit on campus? Jeffrey: The Career Center is somewhat helpful, but most of the resources that many students use are directly through their departments/programs. There are many great companies that recruit on campus, but I dont have experience with them since they mostly recruit the more business-related majors. VT: How are the various study areas such aslibraries, the student union, and dorm lounges? Are they over-crowded, easily available, spacious? Jeffrey: The libraries and student union are always popular places to be. The MU (memorial union) is huge but still always full, though finding a table during lunch isnt impossible since there is ample seating outside as well. The libraries are a bit hit or miss. The main library seems to be a magnet for students who want to look like they are studying while they socialize, which is very frustrating for those actually studying. The Engineering and Science specific libraries are therefore the places to go if you actually want to get work done. Some dorms provide decent lounges for studying but those are at the whim of how quiet your fellow residents are. 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? Jeffrey:The area immediately surrounding campus can be very fun. Mill Avenue is just a block or two from campus and is one of the two major nightlife scenes in the Valley. There are also some very good restaurants, both fast and sit-down, within walking distance of campus. With on campus light rail stops, downtown is also easily accessible. Though not many students go downtown outside of heading down to see a ball game or visiting a museum. We also have the Gammage Auditorium right on campus that has national tours of big popular musicals/shows throughout the year. VT: How big or small is the student body? Were you generally pleased or displeased with the typical class sizes? Jeffrey: Huge. Last I heard, we were still going back and forth with OSU for the biggest campus size in the country. With that huge size came packed classes. The biggest class I took had 750 students in it. The smallest class I had was still around 15 students. So, it does take some getting used to. I would have liked to have smaller classes, but the sizes become much smaller once you get into the 300-400 level classes more specialized in your major. VT: Describe one memorable experience with a professor and/or class. Perhaps one you loved the most or one youregretthe most. Jeffrey: I think by far the best experience has to be my entire year spent taking Organic Chemistry I/II. Yes, I know this is insane, but Dr. Ian Gould is seriously the best Chemistry professor in the world. He was helpful beyond what any student could expect, posting all classes hours online after the class (which was at 7:30 AM, and yes, it was still worth it!). He also ran weekly review sessions every Saturday and at least three review sessions before every test. Most importantly, he actually made the challenging subjects very fun to learn and study. Luckily, he was not the only professor who seemed to make everything about learning fun. I have to say my Biochemistry professor, Dr. Redding, was nearly as amazing as Dr. Gould, while many other professors shared great enthusiasm and dedication to helping students succeed.

How to Get the Vocal Range of Famous Singers

How to Get the Vocal Range of Famous Singers Sign up successful 1. Chest Voice Our chest voice is our main voice and typically is where we sing the notes we are comfortable singing. Chest voice for men typically is lower than a chest voice for women. Most famous female singers sing in chest voice â€" the easiest for them. However, most famous male singers sing in their mixed voice. 2. Mixed Voice Mixed voice is the voice above the chest voice; here, men are able to sing higher notes (think Chris Brown and Trey Songz). Notes in mixed voice for women are typically higher than chest but not as powerful as their full voice (most famous female singers do not typically use their mixed voice very much). 3. Falsetto Both men and women have falsetto â€" although many women typically don’t sing in falsetto. Most people do not count falsetto as part of their vocal range, but a falsetto can still be very useful; if you’re a man and can’t sing certain notes, using falsetto to reach them can prove helpful. Male singers who use falsetto are Chris Brown and Justin Timberlake. Female singers who use falsetto are Leona Lewis and Beyoncé. Falsetto is basically your “false voice” and is what some people refer to as your “girl voice” when referring to male singers. 4. Head Voice Head voice is quite uncommon among both male and female singers, and even rarer in male singers. Head voice is typically less than an octave and notes in this voice are high and powerful â€" think Leona Lewis, Beyoncé, and Ariana Grande. Men can sing in head voice but typically cannot exceed its typical range â€" up to about E6 â€" while women can sing up to about G6 (like Ariana does), but it is highly recommended that you do not exceed its suggested range (G5 to E6). 5. Vocal Fry/Whistle Register Vocal fry is extremely rare in music and typically only used in country music. Vocal fry is typically only used by male singers and notes in this voice are very low. Whistle register is also extremely rare and for most people the only singer they know who can sing in whistle is Mariah Carey. Most people know very little about this voice and though many suggest you cannot sing in this voice â€" especially men â€" I think that anyone can reach this voice. Suggested Video: What is My Vocal Range? How to Expand Your Voice Anyone can expand their vocal range but it takes a lot of practice, time, and patience. I used to be able to only sing in chest voice and falsetto, but now I can sing in every voice that I mentioned â€" I have around a 6.8-octave vocal range. If you want help expanding your range then just hire me as your tutor and I’ll help you expand it little by little with every voice lesson. Here are the steps well take: First step:  Discovering your current vocal range is our first step. I will play a virtual piano, and you will sing each note I play (if you have mimicry then this will be easy) until we have found your vocal range. If you know your range already then we skip this step. Second step:  We then discover your weak spots â€" where your voice sounds weak, where you have trouble, and where you need help. After this we can then start expanding your vocal range. Third step:  I will then teach you and give you tips and suggestions on how to sing lower or higher â€" depending on what you want. Here is where our lessons will vary completely seeing as each student is different. Fourth step:  Every time we discover a new voice I will teach you to bridge your voices together so there is no gap between them. Typically this is our last step with each voice. Working with a voice teacher is also key if youre trying to learn a particular  song a professional instructor can give you specific tips and pointers to help you.

How To Fix American Schools

How To Fix American Schools There has been a lot of talk and buzz about how bad the American education system is, why its so bad and whose fault it is. And on the fault side, nearly everyone who is connected to education has been blamed for the lackluster system. But, what happens when we stop talking about why it stinks, and start trying to make it better? The District Administration tried to answer that question. The 2009 Program for International Student Assessment (PISA) compared the achievement gains between American and foreign students. It found that American students were not achieving as quickly or as strongly as many other foreign countries, thus starting a nationwide panic around Americas educational system. The most important take away from the report is that the strategies the most successful countries are using with only a few exceptions are not being used in the U.S., Marc Tucker, president and CEO of National Center of Education Economy (NCEE) and author of the NCEE report, Standing on the Shoulders of Giants: An American Agenda for Education Reform, told the District Administration. Tucker outlined several reasons why Americas education system is lackluster, most notably he claims that the system has become a business, designed after Americas mass production model. He argues that education was concerned primarily with driving costs down as low as possible, and the quality of education became secondary. However, Tucker offers suggestions on how to actually fix the education system. The following are from Tuckers Standing on the Shoulders of Giants: An American Agenda for Education Reform and the NCEEs report. Aligning the Curriculum: Students should take gateway exams between different levels of education. Most high-achieving countries administer gateways exams to help students transition from basic education to upper secondary education, from upper secondary education to university, from basic education to job training and from job training into the workforce. There is some form of external national assessment at each of these points. In many countries, students cannot move on to the next level unless they pass the gateway exams, which are designed so students cannot study for them. The only way to pass is to truly master the material. Raising Teacher Standards: Many other countries teacher-training programs are much tougher than Americas to get accepted into, thus making it much more competitive to actually become a teacher. However, America cannot raise their teaching standards until the raise interest in the field. America first needs to attract more people to the teaching industry. Many countries pay their teachers better and offer better incentives. Shanghai waives charges for teacher education tuition and offers early admissions to students applying to teacher education programs, which makes teaching very attractive. Shifting Financing for Equity: The NCEE states that school financing should be moved from the local level to the state level. Local financing is simply not fair because many schools districts have a lot more money than others. A state-run system of distributing nearly all funding and resources could create more financial equity, giving all students a chance to achieve, regardless of their schools neighborhood.

How to Discover Your Personal Brand and Tweak if for Career Advancement - Introvert Whisperer

Introvert Whisperer / How to Discover Your Personal Brand and Tweak if for Career Advancement - Introvert Whisperer How to Discover Your Personal Brand and Tweak if for Career Advancement It is seldom discussed on how to define your personal branding and what the process is. Firstly, in order to discover your personal brand you need to understand who you are, what motivates you, and what elements are important in your career. Your personal brand is a reflection of whom you already are, and not a creation of whom you want to be. In other words, you discover and not create your personal brand. Personal branding should convey your talents, values, current skills, personal style or personality. The specific qualities you possess articulates a personal brand and sets you apart from others and competitors. Define what is unusual and unique about you by answering these questions: What is your core essence? What type of person are you like to work with? How would people describe their experience working with you and what would they most remember about you? For decades, we have all been talking about personal branding which year ago was a relatively obscure concept until recently in spite of the essential insights being more or less the same. Personal branding means: Being your own corporate brand Can and should be entirely owned by you This is an on-going process that continually evolves It defines how you live and engage in your personal life and professionally Discovering your personal brand will take time, and of which is a well worth investment. Once you have defined your brand and align it with who you are, then only will your life both personal and professional become valued, happy and fulfilling. Remember the best investment in your life is you, and there is no time like the present to invest in yourself. If you want to advance in your career, one of the essential tools is defining and utilizing your personal brand. Personal branding is creating a personal statement of who you are and what you can offer and do for your audience. This sets you apart from your competitors and allows you to express your uniqueness which in turn will emotionally connect your target audience that will want to work alongside you. Here are some simple steps to help you how to discover your personal branding: Self-Assessment â€" the key element to personal branding in knowing exactly who you are. Analyse the various aspects of who are you, what motivates you, your behaviour and what you want to achieve. For instance, look at what type of personality you are and your values and interests, your skills and experiences of which are both noteworthy and memorable. When defining these critical elements, you need to be completely honest with yourself. Define your Unique Qualities â€" look at yourself as a whole, your preferences, hobbies and interests and define what qualities are unique. For example, what do your favourite songs, movies and books say about you? What would your friends and others learn by knowing your taste in sports, food or music? What do your favourite interests say about you? How does what you do define your uniqueness and set you apart from your peers in your field of expertise or profession. Real-Time Feedback â€" the way we see and assess ourselves is not always the way other people see us. The best way to find out how other people assess you is to get feedback from a selection of people such as close friends, family members, previous employers, teachers and fellow students, people that have worked alongside you and co-workers. Ask these people to asses you using words and phrases, describing your strengths and weaknesses and ask them if they can identify you with a fictional, historical or famous character. Identify Commonalities â€" analyse all the assessments you received from your friends and colleagues and see if there is any particular ideas, words or images that are similar with your own assessment. When reading the feedback see if there are any themes or words that accurately describe you and any similarities between the feedback and your own assessment. Take the theme and words you have extracted, and see which ones align with your experiences. Focus on Your Key Elements â€" come up with 5 top brand elements and try and rank them. Use the following steps to help you put these elements into perspective: Define your value and what you are best at. Define your target audience and selling proposition. What is your belief, purpose or cause that inspires you? What audience are you targeting and why do you think you are the best person to satisfy their needs. Write a list of these qualities and create a profile that exemplifies the qualities of the audience. Rank the list of qualities in an order that is most important to you. Define why you are uniquely in a position to satisfy this specific audience’s needs. Develop Your Personal Brand Statement â€" once you have completed all of the above steps you are now ready to attempt defining a personal brand statement that says who you are, how you do it, and critically important, why you do what you do. This statement is what delivers a message to your targeted audience and is a consistent piece that most people will agree on. Once you have created good imagery, words or emotions that will help people visualize your brand, you are well on your way to success. One of the most powerful expressions is words which are a powerful beacon for you and others when personalizing a brand. Just know who you are and what you want and then make a positive impact with your legacy, promise and brand. In order to connect deeply with your targeted audience, commit to your brand on an emotional level. Your personal brand must depict your creativity, inspiration and passion to curiously engaged audiences in order to create a memorable experience and in turn they will share it with their friends, family and other communities. Congratulations! You have now defined your personal brand that crystalizes the essence of who you are and it is clear to your target audience why they need you. With social media platforms, you have the ability to manage your own personal brand and reputation, both in real life and online. Once your personal brand is well established, spend time mastering the basic tactics and how to tweak it for career advancement, where you allow your actions to speak. This will showcase what sets you apart from competitors as well as describes the added value you bring making you look more attractive to employers and other prospective audiences. Another important question, is your appearance current? Yes, this is important, and if it does not then take a look at the 10 tips to make a first great impression that will help you shift your minds set and establish a professional image. Bear in mind, if you do not brand yourself, others will brand you. You may presently be secure and happy in your current position; however, you never know when things can turn around. Here are some valuable tips using your personal brand and how to tweak it for career advancement and prepare for possible future changes: The first step is to start thinking and talking differently about yourself and your future. No matter your age, do not use this as an excuse not to get the career opportunity you want. Focus on the wealth of experience you have already gained and your past accomplishments which are the foundations of your career brand in comparison to other people. You need to focus and plan on what you want your career brand stands for and then devise a strategy in order to gain additional experience by taking on new challenging assignments that will not only build your brand but cover any weaknesses. A minimum amount of education is necessary for most careers, and to excel you may need to complete additional education, training, or certifications. Your career brand can be greatly enhanced by furthering your education. Ask for advice from a mentor that has already branded themselves well and is highly respected in their field. If you have an amazing brand you need to promote yourself. If no one knows about your brand, you are not going to have any success with your career development. A good place to start is listing all your key accomplishments, education and skills on your Resume, which is the oldest tool used for promoting career brands. Your brand needs to have a very strong presence both on and off the line. Include all important information in your resume such as a list of detailed accomplishments, honours and awards, mission statement, samples of work, speech transcripts, working papers and more, which will afford you a strong on and off-line presence. Establish yourself as an expert in the field that will increase your career brand credibility. Play up your recognition and awards as that will verify your expertise. Construct a website or blog and publish your articles on there. Last but not least, one of the most powerful tools of promoting your career brand is building a strong network community online and word-of-mouth.

Colleges Replacing Loans With Grants

Colleges Replacing Loans With Grants Colleges are replacing student loans with grants in the same amount, according to an article in the Washington Post. So, instead of taking out a $5,000 loan to pay for college expenses, your college might just give you a $5,000 grant. This is a growing financial aid initiative to eliminate student loans at some of the nations most expensive colleges. No-loan pledges can even make college free for some students, if they would need full financial aid to attend. This movement started during the 2007-2008 school year, and now more than 70 colleges offer this program to some of their neediest students. Four years later, some of these students have now graduated, completely debt free. College debt has been rising at record rates the past few years, and economists believe that it could reach $1 trillion this year. This news put expensive colleges on the ropes, forcing them to take action. No college wants their students graduating with over a $100,000 in debt. So, colleges had two choices: decrease tuition or offer more grants/scholarships. Most decided to go with grants. Colleges simply dont have the money they had 10 years ago, and many desperately need to increase enrollment to generate more revenue. Higher education is becoming a buyers market, as colleges are tripping over each other to offer the best deal to students. Offering more financial aid/scholarships is the easiest way a college can attract more prospective students. Colleges have since responded by offering these no-loan pledges to their neediest students, making college a possibility for low-income students. The grants are also part of larger publicity stunt for colleges. When colleges prices skyrocketed, higher education got a bad reputation. It started becoming an elite group, something just for the upper class and upper-middle class. For many low-income students, college simply was not an option. Now, colleges are competing not only on price, but also on reputation. Colleges want to have the best reputation of admitting low-income students. Theyre essentially chasing after the same group of low-income students who are academically talented, Mark Kantrowitz, an industry expert who is tracking 73 collegesthat have eliminated or capped student loans told the Washington Post. If you get in, these schools are a great deal. No two colleges have the exact same financial aid system. But, Harvard and Yale (two of the nations wealthiest colleges) do not allow families to pay more than 10 percent their household income on college expenses. For example, a student from a family with a household income of $100,000 will not pay more than $110,000 (10 percent) for college costs. Even families that earn $180,000 are receiving non-merit based financial aid to wealthy universities like Harvard and Yale. Other colleges cap loan debts for students, but the cap depends on the students family income. But, still many colleges cannot afford to hand out big financial aid grants to all their needy students. For the most part, only the nations wealthiest colleges can afford this program. Code: 3T4D6PGG25SS
