##### Common Forum / Age Calculation
« on: April 28, 2012, 11:04:31 AM »
Here you can find the age using some tricks. You can play these trick as instructed, with your parents or friends and prove your talent to them.

Age Calculation Tricks:

Step1: Multiply the first number of the age by 5. (If <10, ex 5, consider it as 05. If it is >100, ex: 102, then take 10 as the first digit, 2 as the second one.)

Step2: Add 3 to the result.

Step4: Add the second digit of the number with the result.

Step5: Subtract 6 from it.

##### Science Discussion Forum / What is a Tsunami
« on: April 28, 2012, 10:50:34 AM »
Tsunami is the Japanese name given to large waves that sometimes devastated the shores and ports of Japan. A tsunami is a wave in the ocean but it is very different to normal waves.

Tsunamis have very long wavelengths. Crest to crest they measure between 10 and 500 km and they travel through the ocean at more than 700 km/h. Sometimes there appears to be just one wave but often there are multiple waves travelling a few minutes apart.

Wave height [amplitude] may not appear to be great in the open ocean but unlike normal waves the tsunami is moving the entire water column, all the way to the sea floor. The water depth therefore has a major influence on the behaviour and appearance of the wave. In addition because of the wavelength, the first sign of the arrival of a tsunami may actually be the sea level falling and bays appearing to empty.

In deep open water the wave is almost impossible to see although modern instruments can detect it. However, as the wave approaches shore and the water shallows it slows down. The wave rapidly bunches up as the faster rear sections catch up with the slower front sections resulting in the wave growing
in height the closer it gets to shore. This effect is enhanced if the near-shore sea bed provides a long gradual shallowing. Many tsunamis are barely distinguishable from normal sea waves but some turn into monsters rising 30 metres above the shore line. The damage along a shore line may vary because of the influence the local shape of the sea floor has on wave behaviour.

Bays and harbours that are funnel shaped also suffer more from a tsunami because they concentrate the effects. Damage in these areas is further increased by the sloshing backwards and forwards of the water, just like in a bathtub.

##### Common Forum / We should change the present system of education in our country.
« on: April 27, 2012, 08:43:06 PM »
As we are a developing country, a good education system keeps the foundation of prosperity and success for the country. If our country wants to be independent and economically well, then it needs to check the education system.

- There is a need for more innovation in the education system.
- More advanced technologies should be used in this sector in order to compete with other countries.
- More and more amendments should be done to make students more physically fit and mentally strong.
- Schools, colleges, universities and other institutes should focus more on the development of an individual.
- Schools, colleges, universities and other institutes with education should teach values and manners.

##### You need to know / Hard work or Smart work - Which one is more important?
« on: April 27, 2012, 08:30:19 PM »
Work is important to do as it takes us to the next level of success. The most important question you should ask at this place is what kind of work will take you to that level, is it hard work or smart work.

For

- Smart work is really the need of the hour.
- Smart work saves lots of time and allows you to be more organized.
- Through smart work your goals can be reached faster.
- Doing smart work allows you to save time for other things which you might not get by doing hard work like, exercise, spending time with family etc.
- Smart work brings lots of recognition from the society and allows you to grow more in the industry you are in.

Against

- Hard work takes lots of time just to make things correct.
- It is totally time consuming and exhausting experience, as after doing lots of work you left out with less energy to do anything else.
- Hard work doesn't allow you to fully use your brain and it pushes you for more physical work.
- In terms of determination and persistence hard work is really important but not lot can be achieved.
- Working hard is not enough as it might not bring the best result of a problem or a situation.

I would like to conclude in the end that smart work is really important as it saves time and allows you to reach your goals faster than that of a hard work.

##### Common Forum / QUALITIES OF A GOOD STUDENT
« on: April 26, 2012, 10:34:47 PM »
we know Todayâ€™s students are tomorrowâ€™s leaders of a country and the qualities of the student clearly determine the students bright future and carrier path. So, who is a good student? What are the qualities of a good student? Historically, the term â€˜studentâ€™ referred anyone who learns something. However, the recent definition of a â€œstudentâ€ is anyone who attends school, college, or university.

Again, what are the good qualities of a student? Based on my personal experience and research, I list down the qualities of a good student.

1. Attitude: Basically, a good student possesses the ability and willingness to learn new subjects even the subjects are not interesting.

2. Academic skills: Acquiring academic skills is the most important quality of a good student. Ability to read comprehensively, to write effectively, to speak fluently, and to communicate clearly are the key areas in which a good student must be proficient. Having a good handle in all these areas will make a student to shine in a class.

3. Ability: A good student has the ability to apply the results of his or her learning in to a creative way and achieve the goals.

4. Perceptiveness: How well a student can interpret and perceive meanings from a conversation greatly determines the quality of a good. A good student always perceives right meaning from conversations, but an average student often misunderstands the original thoughts of a speaker or writer and derives a wrong conclusion.

5. Self-Discipline: Discipline in managing the time is an important factor that every good student must possess. Often times, delaying the tasks, such as writing assignments, reading text books, etc, may negatively impact the ability of a student to achieve the goals.

6. Understanding rather than memorizing concepts: A lot of surveys suggest students must understand the concepts rather than just memorizing them. The memorized facts and theories will stay in studentsâ€™ memory until they leave school, college, or university. Once out of school, the students will totally forget the core concepts that they learned. Therefore, it is essential a good student understand the concepts.

7. A good student must be a good listener and good manared. His/her attitude and behaviour with others must be good.

##### Science Discussion Forum / The Metonic Cycle
« on: April 25, 2012, 10:26:33 PM »
The Metonic Cycle is the Moonâ€™s 19-year cycle where the Moon returns to exactly the same place (at the same longitude and against the same constellation) in the sky with the same phase. The Metonic Cycle is a period of about 6939.6 days, the approximate length of both 235 consecutive lunations and 19 solar years. Knowledge of this cycle is important in determining when to assign intercalate months to lunisolar calendars. Meton, an Athenian who lived in the middle of the fifth century B. C. is the cycle's namesake. Meton himself referred to it in a publication as the nineteen-year cycle. There is some question as to whether Meton discovered it on his own or whether he learned of it from Babylonian sources, because it was discovered there about fifty years before Meton's time. Lunisolar calendars have twelve lunar cycles in their common years. That's about eleven days short of a solar year. Each month starts on the day of a new Moon, or on the day a new lunar crescent is first sighted. Without intercalation, months start eleven days later in relation to seasons each successive year. An ordinary calendar is a solar (Sun) calendar. It keeps the dates in sync with the Sun. For instance, the Sun is at its highest point as we view it around the 21st of June â€“ the summer solstice. The solar cycle (a year) takes 365 and a quarter days to complete. Every four years is a leap year when an extra day is added to the year. This accounts for the quarter day and keeps the date nearly in sync with the seasons. The cycle is not quite 365 and a quarter days. The error is 3 days in 400 years. A lunar (Moon) calendar keeps the lunar dates in sync with the Moon. For example, the 1st of the month could be on the new Moon. Then the 7th of the month would fall at the waxing half Moon. The dates vary for different types of lunar calendars, Muslim, Chinese, Buddhist, Jewish etc. Some have the 1st on the full Moon. However, all follow the Metonic Cycle that keeps the lunar dates in sync with the Moon.

# Tropical Lunar Month: The Moon returns to the same spot in the sky (against the backdrop of the same constellation) every 27.322 days, which is called the Tropical Lunar month. However, the Moon's phase is not the same for two days.

# Synodic Lunar Month: The Moon returns to the same phase every 29.5306 days and is called the Synodic Lunar month. There are 12 synodic months and 13 tropical months (returns) in one year. Therefore, it takes 19 years (or 6939 days) for the Moon to return to the same spot in the sky at same phase. This can be seen as: 19 tropical years - 365.24 days x 19 = 6939.56 days,
235 synodic months = 29.5306 days x 235 = 6939.691 days,
254 tropical months = 27.322 days x 254 = 6939.788 days.

# Lunar Leap Year (LLY): To keep the Moon's cycles as close to the Sun's cycle, an extra synodic month and an extra tropical month are added. So instead of 12 synodic months and 13 tropical months in a year, it is 13 synodic months and 14 tropical months.
