STM squared = SM squared + TM squared = Constant. (1)
Einstein described the time dilation of traveling clocks in 1905. The "twin paradox" was first noticed in 1911, when Paul Langevin restated time dilation in the now famous "paradox". Paraphrased, he wrote: "Pam, Jim's twin sister, undertakes a long and fast round-trip in space. On her return to Earth, she finds that her twin brother has aged quite a bit more than herself".
It is called a 'paradox' because skeptics argue that after the Pam has reached her cruising speed, she could consider herself as stationary and that it's Jim (on Earth) that rushes away from her at great speed. In such a case, Pam must be aging faster than Jim. This is not the case however, as has been verified experimentally in particle accelerators many times.
The solution to the paradox lurks in the fact that Pam has been accelerated for some parts of the trip, while Jim has not. However, experiments have also shown that acceleration does not directly affect good atomic (or biological) clocks. It is only the time that Pam spends traveling at the high speed relative to Jim that determines how much younger than Jim she will eventually be.
Einstein's relativity theory demands that space and time should be considered together as an entity called space-time. When Pam and Jim are together and stationary on Earth, they both acquire the space-time movement of their location on Earth. Since they do not move relative to that location, their space-time movements are the same as their time movements (the rate at which they grow older).
This acquired rate of space-time movement remains constant for both twins. As soon as Pam moves away from Jim, the change in the rate of her space movement (SM) is "subtracted" from the rate of her time movement (TM) in order to keep her acquired rate of space-time movement (STM) constant. Actually, it is the squares of the rates that are added/subtracted, which can be stated like this:
STM squared = SM squared + TM squared = Constant. (1)
It is like using the Pythagoras theorem for finding the hypotenuse of a triangle, only in this case the hypotenuse remains constant and the other two legs of the triangle can change, but they must satisfy the theorem.
While Pam is moving relative to Jim, she retains her rate of space-time movement, meaning that her rate of time movement must come down. Since the values are squared, it does not matter in which direction the movement is; the effect is the same for her outbound trip and her inbound trip.
To give some practical values: let Pam travel away from Jim at 60% of the speed of light and turn around after 4 years on her clock. If she returns at the same speed, it is obvious that she would have aged 8 years on her trip. However, she would find Jim to be 10 years older than when she left him, and he will have the birthday cards to show that! This should please Pam?br />
Let's verify the values with equation (1) above: Jim has not moved through space, so for him: STM squared = 0 + 10 squared = 100. Since Pam has moved, we must know how far she has moved according to Jim. At 60% of the speed of light for 10 years, she must have done a total distance of 6 light-years, hence for Pam: STM squared = 6 squared + 8 squared = 100, satisfying the theory.
That's it, girls! As Pam has shown, travel keeps you young!
Once an individual is granted an associate degree,
Recent studies have shown more strongly than ever that getting an associate degree online is one of the smartest investments in the future a high school graduate can make. Traditionally many people have felt that an associate degree is just a stepping-stone to a bachelor degree, but this is quickly becoming the exception rather than the rule. Today's students can get an associate degree online that puts them in the workforce sooner, costs less and is more targeted to their career choice.
No Typical Associate Degree Online Student
When you look for students who are pursuing an associate degree online, you won't find one person who is "typical." The range of students is astounding, with more diversity by far than you'll find on a traditional college campus. Because of the financial savings and the flexibility of the schedule, there are more non-traditional students in an online program. In any given class, you might find:
Working parents who need to study at night or during work breaks and can't attend classes on campus.
Military personnel and their spouses, who move around frequently and can't commit to one campus location.
Students with disabilities who can work more comfortably and efficiently from home.
Those returning to get an associate degree online because they are older and might not feel comfortable in the classroom with students much younger than them.
Improving Your Life with an Associate Degree Online
The United States census, various educational and government agencies and even financial analysts have been taking a good, hard look at associate degree programs in recent years. When they compared information and statistics they discovered that the advantages of earning an associate degree online were overwhelming:
The average difference in salary between a high school graduate and an individual with an associate degree is in the six figures over a lifetime, with the typical difference over a lifetime of working being somewhere around $140,000.
Once an individual is granted an associate degree, he or she can typically begin earning about $130 more every week than his counterpart without a degree. For those with associate degrees in computers, engineering or accounting the difference is even greater.
Individuals with an associate's degree are far less likely to be unemployed than those with only a high school education.
If you then figure in the money saved by pursuing an online degree instead of attending a traditional college, you'll see just how valuable your degree can be. After all, attending an online college means you've:
Continued to make money by working while you attend classes.
Saved money on transportation (whether on gasoline and parking or public transportation).
Skipped the investment in activity fees, meals on campus and even additional clothing by studying at home.
Is it any wonder that one well-known financial analyst recently referred to the value of an associate degree as a "slam dunk" with massive payback for students? If you want to gain this payback for yourself, check out getting an associate degree online. It's the best way to advance your career with the least financial outlay. You'll see the return many times over.

The standards are the highest found in any country in the world
Since 1996, the term "chartered certified accountant" has been used to define a British qualified accountant and is awarded to qualified applicants by the Association of Chartered Accountants. This elite group of accountants, granted Royal Charter by the Queen, specializes in business accounting, management accounting, financial accounting and even forensic accounting, among others. While many choose to take the private business route, others prefer the organized confines of a government agency.
Not surprisingly, the Association of Chartered Certified Accountants, or ACCA, is the world's fastest growing accountancy groups. Currently, there are more than 140,000 members, more than 400,000 affiliates and the association is present in at least 150 countries. The group is headquartered out of London, England and dates back to the early 1900s. It initially began as the London Association of Accountants and its goal was to provide transparency in the financial industry. It was not until 1930, however, that the group was finally given the green light to audit companies. After several merges and reformations, in 1974, the Royal Charter was extended and in 1995, the name that is now known was bestowed onto the association and the elite members were allowed to use the designated Chartered Certified Accountant.
The standards are the highest found in any country in the world and current qualifications include fourteen professional examinations, thirty six months of supervised accountancy experience and upon completion of Part 2 of the Professional Scheme, a degree in Applied Accounting is then required from students. The minimum guidelines are quite definitive and unyielding. While there are the occasional exemptions from at least part of the fourteen examinations, students are required to prove their knowledge in financial accounting, management accounting, taxation, company law, financial management, corporate reporting, audit and assurance and financial reporting prior to any exemptions being extended.
A new syllabus, passed in December 2007 and put into effect right away, updated the qualifications as a result of the accountancy field and its advances. It is not uncommon, and in fact, is even expected, every several years and in accordance with the changes and updates in a global financial market. At one time, examinations were held on an annual basis; now, however, they are held bi-annually and in several countries. It is likely this could change as well as demand dictates from an ever expanding field.
Besides the United Kingdom and the Republic of Ireland, legal acknowledgement of the ACCA is left to each country. Members are afforded the option, in those countries that choose not to acknowledge the association, to apply for advanced standing when applicable. And too, there are those countries that don't require this application and simply choose to extend the courtesy.
Finally, the ACCA offers its members certain access to those committees that acknowledge the body. The Financial Services Institute of Australasia recently signed a partnership agreement, as has the Institute of Internal Auditors, the Chartered Institute of Taxation and those professional bodies in Canada, the United States and several other European countries.
Learning components such as project work and team exercises
Flexible learning is all about delivering quality education around the needs of the student who has work and family commitments. The philosophies and theories of flexible learning concern making education accessible to a broad range of students, and enabling students to make the most of the learning in the time frame and course structure that is right for them.
Thanks to the technologies of e-learning, such as the virtual learning environment and online degrees, flexible learning is a strong feature of many online courses available to students in full time work.
Flexible distance learning suits employers too, because students often find that an online or distance learning course will fit in around their work /family schedule. Furthermore, staff at colleges that offer courses delivered via the flexible learning format will also understand that their students are also professional people.
This helps in two main ways ?that teachers of online degrees and flexible learning will recognise that the course needs to be delivered with the student抯 other responsibilities in mind, and that they could be in a career that will both contribute to, and benefit from, their chosen path of flexible learning.
Engaging students in the e-learning environment is the key to making sure the technology is accessible, functional and easy to use. This sits comfortably with the philosophy of flexible learning, where focusing learning resources and course work in tune with the professional schedule of the student can achieve better engagement with the online education.
Learning components such as project work and team exercises are accessible through flexible learning online courses, thanks to the capabilities of the virtual learning environment. Web based applications can facilitate a range of learning functions that in many ways can have a better impact on student results than a conventional campus based college.
So, although flexible learning is not necessarily dependent on a range of web based technologies, when the technology exists to support and develop the delivery of online education, then it can only expand the range of students who may not otherwise find it possible to study for an online degree.
The future of flexible learning seems to be more and more linked to the development of the virtual learning environment. For instance, distance learning courses now feature a much greater range of learning and study activities thanks to innovations and development of Internet education applications.
Yet the self-motivation and discipline attributes of the student remain the same as any learning or education platform for any flexible or distance online learning programme to be of benefit.
Studies show though, that employers see flexible learning as a necessary path to increasing their employee抯 skills and knowledge, with a professional attitude to studies already engrained from study-related aptitudes in the workplace.
Far from being an easy approach to learning, flexible learning merely exists to support students who would otherwise find it impractical to attend a college in a traditional setting. For employers and staff alike, flexible learning is the education platform of choice.
As previously mentioned the test has three parts while includes
As you may be very well aware of the Praxis series comes in threes but perhaps the Praxis that has much density among all three is Praxis II. This area gauges the understanding of certain subject matters of the applicant as they were about to teach k-12 students. There are also portions for general and precise teaching abilities and facts to which subject assessments, Principles of Learning and Teaching (PLT) and the Teaching foundation types are under. There may be various reasons why a person decides to take this test but definitely one of those reasons would include the need to acquire a professional license which most states and even organizations and associations look for as a requirement.
You maybe aware that this test could be taken by two options, the first option are the computer-based while the other one is the paper-based examination. Praxis II is the exam included under the paper-based assessment, wherein the testing areas are located in a variety of testing areas all over the region or state. Sine ETS aims to promote standardization and fair-play, in the event that an applicant doesn抰 use English as a main language he is given a non-standard test at a complementary testing area.
Test arrangement
As previously mentioned the test has three parts while includes, subject assessment portion. This part calculates the subject matter understanding and ability of the applicant, the test is in a multiple-choice and an essay-type format. Next portion goes to the Principles of Learning and Teaching (PLT) examination, this certain portion aims to gauge the academic acquaintance a the four grade levels of the applicant such as early childhood, k-6, 5-9, and 7-12. A case study method was employed in this portion and requires essay type of answers and has multiple-choice answered numbers.
The last portion is devoted to the teaching foundation test which intends to calculate the academic proficiency of the applicant in the major fields of education such as English, language, arts, science, mathematics, and social science. The questions in this area are answered with an essay and by having to choose a letter from the multiple-choice options that are presented. A sufficient time of two to four hours is given to the applicants who are taking the examination.
Coverage of Praxis II
This portion of the exam has 12 subject matters which the applicant has to pass. And the subject matters are Agriculture with the test number of 0700 and a passing score of 530, business with the test number 0100 and the passing score is 560, English has a passing score of 159 with a test number of 0041, Both the foreign language French and Spanish has a passing grade of 157 with the test numbers 0173 and 0191, respectively. Math Middle level has 148 passing score and a test number of 0069, math secondary has a passing score of 121 with the test number 0061. The subject biology has a test number of 0231 and a passing score of 150 while chemistry has a passing score of just 127 and a test number of 0241. General science has a passing score of 13 and a test number of 0432 while physical science has a passing score of 147 with the test number of 0481. Last subject in Praxis II is physics with a passing score of 112 and a test number of 0261.
