Not only we want happiness, but also our friends and relatives, and even strangers. We want them all to feel our happiness. The joy of sharing the joy beyond joy in having.

At the beginning of AD era, in Asia there are two big countries that are considered high level of civilization, namely India and China. Both the country's economic and trade relations are good. Flows of trade and shipping traffic going by road and sea. One of the marine traffic that passed the India-China is the Strait of Malacca. Indonesia is located in the path cross the position of two continents and two oceans, and near the Strait of Malacca has its advantages, namely:

1. Frequently visited by foreign nations, like India, China, Arabic, and Persian,
2. Opportunity to do international trade relations are wide open,
3. Intercourse with other nations increasingly widespread, and
4. Foreign influences into Indonesia, such as the Hindu-Buddhist.

The involvement of the Indonesian nation in trade and international shipping activities causing the mixing of cultures. India is the first country to give effect to Indonesia, namely in the form of Hindu culture. There are several hypotheses suggested by experts on the Hindu-Buddhist cultural entry into Indonesia.

1. Hypothesis Brahmin
This hypothesis was revealed that the Brahmin is very instrumental in efforts to spread Hindu culture in Indonesia. The Brahmin got an invitation from the Indonesian authorities to enthrone the king and led the religious ceremonies. Supporting this hypothesis is Van Leur.

2. Hypothesis Knights
On the hypothesis knight, the role of the spread of religion and Hindu culture performed by the knighthood. According to this hypothesis, in the past in India often occur antargolongan warfare in society. The soldiers who lost or bored faces of war, then left India. Apparently, among them some are up to the territory of Indonesia. These are then trying to establish new colonies as a place of residence. In places it is also possible the spread of Hindu religion and culture. FDK Bosch was one of supporting the hypothesis knight.

3. Hypothesis Vaishya
According to the proponents of the hypothesis Vaishya, Vaishya from the merchant group has been instrumental in spreading Hindu culture to the archipelago. Traders deal with the rulers and their subjects. Interwoven relationship has opened opportunities for the deployment process of Hindu culture. NJ Krom is one of the supporters of the hypothesis Vaishya.

4. Hypothesis Sudra
Van Von Faber revealed that the battle that occurred in India has led faction sudra become outcasts. They then left India by following the Vaishya. With large numbers, allegedly contributing sudralah class in Hindu culture spread to the archipelago.

In addition to the above opinion, experts suspect a lot of young people in Indonesia who studied Hinduism and Buddhism to India. In overseas they founded an organization called Sanggha. After gaining the knowledge that many, they returned to pass it on. Such an opinion is called Reverse Flow Theory.
In general, experts tend to the opinion which states that the entry of Hindu culture to Indonesia was taken and distributed by the Indonesian people themselves. The earliest evidence for the influence of Indian culture in Indonesia is the discovery of a bronze statue of Buddha in the area Sempaga (South Sulawesi). Judging from its shape, this statue has a style similar to the statues are made in Amarawati (India). Experts estimate, the Buddha statue is the merchandise or goods offerings to Buddhist sacred buildings. In addition, many also found the oldest inscriptions in Sanskrit and ancient Malay. News delivered inscriptions that provide clues that Hindu culture spread in the kingdom of Srivijaya in the 7th century AD.
The influence of Hindu-Buddhist cultural elements from India have been changing and adding cultural treasures of Indonesia in several aspects of life.

1. Religion
When entering the era of history, people in Indonesia have adopted the belief of animism and dynamism. People are starting to accept the new belief system, namely the Hindu-Buddhist since interacting with the people of India. The new culture brought changes in religious life, for example in terms of manners, ceremonies of worship, and forms of worship.

2. Governance
Royal government system introduced by the Indian people. In this system of small groups of people united by a broad territory ownership. Chieftain of the best and strongest are entitled to royal power. Therefore, the birth kingdoms, such as Kutai, Tarumanegara, and Sriwijaya.

3. Architecture
One of the megalithic tradition is punden berundak-building steps. Tradition is combined with the culture of India which inspired the building of the temple. If we look at the Borobudur Temple, it would appear that the pyramid-shaped building that staircase the steps. This is a proof of India-Indonesia cultural blend.

4. Language
Kingdoms of the Hindu-Buddhist in Indonesia left several inscriptions that most of the lettered Pallawa and speaking Sanskrit. In subsequent developments even today, the Indonesian language to enrich themselves with the Sanskrit language. Sentences or words of Indonesian language is the result of uptake from the Sanskrit, the Pancasila, Dharma Dasa, Kartika Eka Paksi, Parasamya Purnakarya Nugraha, and so forth.

5. Literature
India's growing influence in Indonesia brought great advances in the field of literature. Famous literary works that they carry is the book of the Ramayana and the Mahabharata. The existence of the books that encourage the Indonesian poets to produce works of their own. Works of literature that emerged in Indonesia are:

1. Arjunawiwaha, works Mpu Kanwa,
2. Sutasoma, Tantular Mpu work, and
3. Negarakertagama, mpu Prapanca work.

Hinduism
Hinduism developed in India in 1500 BC ±. Source of Hindu teachings contained in the Vedic scripture. Vedas consists of 4 Samhita or "set", namely:

1. Reg Vedas, contains the poems of praise to the gods.
2. Same Vedas, containing the sacred songs.
3. Yajur Veda, containing the ritual incantations to safety.
4. Atharwa Vedas, containing the prayers for healing diseases.

In addition to the book of the Vedas, Hindus also have other holy books, namely:

1. Book Brahmins, contains teachings about things offerings.
2. Book of the Upanishads, containing the divine teachings and the meaning of life.

Hinduism embrace polytheism (worship of many gods), of which Trimurti or "Unity of Three High God", namely:

1. Brahmin god, as god the creator.
2. Lord Vishnu, the maintainer and protector deity.
3. Lord Shiva, the god of destruction.

In addition Trimurti Gods, there are many gods who are worshiped Lord Indra carrier rain very important for agriculture, and the god Agni (fire) used for cooking and religious ceremonies. According to Hindu society is divided into 4 levels or castes, called Caturwarna namely:

1. Brahmin caste, composed of the clergy.
2. Caste Knights, composed of the king, the royal family and nobles.
3. Vaishya caste, composed of merchants, and laborers medium.
4. Sudra caste, composed of farmers, small labor and slaves.

In addition to these four castes there are also classes pharia or candala, that is, those outside the caste who have violated the rules of caste.
Hindus choose places that are considered sacred for example, Benares as a place bersemayamnya Lord Shiva and the Ganges water to purify the sins of Hindus, so they can reach the top of nirvana.


Buddhism

Buddhism taught by Siddharta Gautama in India in 531 BC ±. His father was a king named Sudhodana and mother goddess Maya. Buddha means one who was conscious and wanted to break away from samsara.
Buddhist scriptures are Tripittaka meaning "Three Baskets" written in Poly. As for the meaning of the Three Baskets were:

1. Winayapittaka: Contains the rules and laws that must be run by Buddhists.
2. Sutrantapittaka: Contains discourse-discourse or the teachings of the Buddha.
3. Abhidarmapittaka: Contains an explanation of religious matters.

Buddhists must implement Tri Dharma or the "Three Worship" namely:

1. Buddha is devoted to the Buddha.
2. Dharma is devoted to the teachings of Buddha.
3. Prop that is devoted to the adherents-embraces Buddhism.

Besides, for people to achieve nirvana should follow the 8 (eight), the path of righteousness or Astavidha namely:

1. The view is right.
2. True intentions.
3. These words are true.
4. The act is right.
5. Right livelihood.
6. Businesses that right.
7. Attention is right.
8. Meditated correct.

Since the emergence of various interpretations of Buddhist teachings, ultimately grow two streams in Buddhism, namely:

1. Hinayana Buddhism, which every person can achieve on its own nirvana.
2. Mahayana Buddhism, that one can reach nirvana with joint efforts and mutual assistance.

Buddhists also have places that are considered holy and sacred, namely:

1. Kapilavastu, the birthplace of the Buddha.
2. Bodh Gaya, where Buddha meditated and gained Bodhi.
3. Sarnath / Varanasi, where the Buddha first taught the doctrine.
4. Kusinagara, namely the death of the Buddha.

1. MSG / Seasonings Flavor, MSG is proven to make the plants become more fertile. I myself have tried it on my Anthurium plants. And the result looks more fertile plants in just a few weeks. It's easy, sprinkle MSG to plant roots and then flush with water. Or you can mix with water first, then poured into plant roots.

2. Eggshell, after you cook the egg-skin leather should not be disposed of first. One of the nutrients needed by plants is the calcium in large numbers. Nutrition can be found on the egg shell. It's easy, mashed eggs and charcoal until smooth and then spread to the plant roots and then flush with water. Or you can also use waste water for watering plants boiled egg. But remember, wait for the new first splashed cold water.

3. Charcoal ( Wood ), Charcoal offerings have the nutrients needed by plants. Charcoal offerings contain cations K (Potassium), Ca (Calcium), Mg (Magnesium) Si (Silica). Therefore, we often see the land used by the seller sometimes mixed with ash flower offering.

4. Onions Skins, Water remaining onion skin soaking overnight to fertilize crops. According to research onions contain Calcium, Phosphorus and Iron. These elements are nutrients needed by plants.

5. Tea Drags, do not waste the rest of your tea dye, because this tea waste used to fertilize crops dapt. Amas soak the tea into the water and then the next day pour on your plants.

6. Banana Skin, banana skins also contain a high enough calcium needed by the plant. Mashed banana peel until smooth and then dissolve it in water and pour on the plants.

7. Gelatine, agar-agar to fertilize crops. The way of administration is by mixing 1 to 2 tablespoons gelatin powder into a glass of hot water. After the agar dissolves, mix gelatin solution is put in 3 cups of water. After the solution mixed well, pour into the roots of your plants.

8. Drugs Rest (powder / tablet), if this one is quite unique because it seemed to impose .... ^ ^ But it never hurts to try. Mash the remaining drugs of unused / expired and then dissolve it into water and pour into plant roots. This method proved to effectively fertilize plants. Perhaps this is influenced by the content of chemical elements that are in medicines, especially medicines that contain specific elements such as calcium.

Tangent of two circles. Before dividing his case, we note some important points about this chapter (tangent circles). Principal importance as follows:
* The line tangent to the circle perpendicular to a line to the center of the circle (a radius of a circle)
* Remember the Pythagorean formula. Because here will be used hold the Pythagorean formula. Pythagorean formula, namely:

Now we will discuss about the tangent of two circles. Divided into 2, namely:
* The line outside the common tangent
* Common tangent line in
* The line outside the common tangent



Note the picture above!
There are two circles, one circle with center and 2 with the center circle . The radius of the circle 1 we write and the radius of circle 2 we write . Long lines outside the common tangent of two circles symbolized our . The distance of two circle center (a long line connecting the center of circle 1 and circle 2) we are symbolized as
Which is called the length of common tangent line outside?
Tangent length is measured from the point of tangency on the circle 1 to the point of tangency on the circle 2. In the picture can be written as AB.
To find the length of tangent line of external, can be searched by using the formula:
or
Can we exchange the position and ?
Can. That is, we may write . It's okay to do. As long as they'll be careful with negative signs. Negative numbers when squared, then the result is positive. Likewise, positive numbers that squared the result is positive. Thus, by swapping the positions and Our calculation will be the same.
Where are these formulas?
The formula was obtained from the Pythagorean formula. We note the external tangent. Remember! tangent line is perpendicular to the radius. Note the picture!
If the tangent line is we are so touched one of the shear center of the circle, it will get a right triangle. By applying the Pythagorean theorem on right-angled triangle, with j is the hypotenuse, and sides of a long tangent penyikunya is out and the excess of his fingers.
Try using the Pythagorean formula, then the result is a formula that has been given.
* Common tangent line in



Tangent line of the two circles is a red line on the image. Of course, to find the length we can use the following formula:
or
is the length of the tangent line of
The formula is almost the same, just sign in kurungnya now is positive.

How to memorize!


How do I memorize? How do I differentiate outside the tangent formula and the tangent line in? If we like to memorize, just memorize the formula is only on the positive and negative signs.
Only the sign was different. Can be memorized in this way. If outside, the word "outside" ends with the letter r. then the formula minus. The word "in" ending in the letter m, then the formula is added.
Most of the errors students
Majority student error is to change the minus sign and added rather than on his r. That is, a sign that replaced it has worked on after j. For example, for the formula in, they write .. while for the outer formula, they write ... This is wrong. please be careful here.
Hopefully a little help.

In Euklid geometry , a circle is the set of all points on the field within a certain distance, called the radius, from a certain point, called the center. The circle is an example of simple closed curves , dividing the field into the inside and the outside.

Elements of the circle

 The elements contained in the circle, is as follows:

• n a point inside the circle is the reference to determine the distance to the set point of the building so that the same circle. Lngkiaran element in the form of points, namely:
  1. Center point (P)
     is the distance between the center of the circle the price is constant and is called the radius.

• Elements that form a circle ruler, namely:
  1. The radius (R)
     is a straight line connecting the center with a circle.
  2. Bowstring (TB)
     is a straight line inside the circle which cuts the circle at two different points (TB).
  3. Arc (B)
     is a curved line either open or closed which coincides with the circle.
  4. Circumference of a circle (K)
     is the longest arc on the circle.
  5. Diameter (D)
     is the largest bow string whose length is twice the radius. It shares the same diameter circle area.
  6. Apotema
     is the shortest line between the bowstring and the center circle.

• Elements that form the circle area, namely:
  1. Pie (J)
     is an area of ​​a circle bounded by the arc and two radii that are on both ends.
  2. Borderline (T)
     is an area of ​​a circle bounded by an arc with a rope bow.
  3. Discs (C)
     represents all areas inside the circle. The extent of the radius squared multiplied by pi. The disc is the largest pie.  

Equation 

A circle has equation

with is the radius of the circle and are the coordinates of the center circle

Parametric Equations

Circles can also be formulated in an equation parameterik, namely

which if allowed to undergo t will be a circular trajectory in xy space.

Area of circle

Area of ​​circle having the formula

that can be derived by integrating the area of ​​a circle element

in polar coordinates, namely

In the same way can also be calculated vast semi-circle, quarter circle, and parts of the circle. Also do not miss to calculate the area of ​​a ring circle with a radius of and outer radius .

Addition section element

Area of ​​circle can be calculated with the cut it up as the elements of a pie for later rearranged into a rectangle whose width can be easily calculated. In pictures r means the same as R is the radius of the circle.

Area of pie

Broad segment of a circle can be calculated if the area of a circle made ​​a function of R and θ, namely;

with the restriction θ value is between 0 and 3π. When the value θ 2π, the calculated segment is the largest segment, or area of a circle.

Area of a circle ring

A circular ring has an area that depends on the radius in and outer radius , Ie

where for this formula back into the formula area of ​​a circle.

Area of a circle cut ring

By combining the two previous formulas, can be obtained

which is the area of ​​a ring was intact.

Around the circle

Circumference of a circle has the formula:

The length of arc

Length of arc of a circle can be calculated using the formula

derived from the formula for calculating the length of a curve

where used

as a curve in a circle. Sign suggests that there are two curves, namely the top and bottom. Both are identical (remember the definition of a circle), so that really only needs to be calculated once and the result multiplied by two.

Musical instrument played down the effects of aging especially related to hearing. A study in the United States reveals, those familiar with musical instruments throughout his life has the capability of hearing and a better memory than those who never touch the music.

"Practice music may prolong life, improve memory, and improve the ability to hear speech in noise," says Nina Kraus, authors of the study which served as the Director of the Auditory Neuroscience Laboratory at Northwestern University, United States, as quoted by the Daily Mail.

In their study, researchers involved 18 people musicians and 19 non-musicians ages 45 to 65 years. They asked respondents to listen to speech in noisy atmosphere. They also conducted a series of tests such as tests of visual memory, voice recording capability, and ability to hear.

The musicians learn to play musical instruments at an early age or under nine years old and still active until now, managed to beat the non-musicians in all tests. However, in tests of visual memory ability, both groups showed almost identical ability.

Doctor Kraus said, the experience of extracting sound from a wide range of musical instruments and sound sequences given the increasing development of auditory skills. "Playing music involves their ability to retrieve relevant patterns, including their own voices, instruments, harmony, and rhythm."

Dr. Kraus said, practicing music can improve memory and auditory nervous system. "The experience of musical communication can combat the problems associated with age," he said, adding that the study was published in the scientific journal PLoS One recent issue.

Strengthening these findings, other studies revealed that giving children music lessons could become a training to increase the concentration of learning in the school. Learning music can also reduce some negative effects of aging.

This could cause the vomer bone (thin bone that separates the nostrils), which connects the nasal passages to the mouth back and forth, says Lisa DeStefano, an assistant professor at Michigan State University college of osteopathic medicine. After 20 seconds, the movement will loosen the clogged nose.


3. Stopping a nosebleed
Pinch your nose and leaning back is the best way to stop a nosebleed. The other way is more comfortable and Put the cotton on the upper gums (tissue that covers the lower jawbone and teeth) behind the bottom of the nose and press with a vengeance. "Most of the bleeding coming from the septum, the cartilage wall that separates the nose" says Peter Desmarais, ENT specialist at Entabeni Hospital, in Durban, South Africa. "Pressing here helps stop the bleeding."


4. Eliminate burning
When you touch the hot stove by accident, clean the skin and give a light massage with the finger is not injured. And the ice will relieve pain, said Dr. DeStefano, because the burned skin back to normal temperature, the skin is less likely to blister.

5. Preventing gastric acid
Research shows patients who sleep on their left sides are less likely to suffer from stomach acid. Esophagus and stomach associated with the position. When you sleep on your right, the stomach is higher than the esophagus, allowing food and stomach acid flows into the esophagus. If you tilt to the left, the stomach is lower than the esophagus so stomach acid does not flow into the esophagus.

6. Cure your toothache without opening your mouth!
Rub ice on the back of your hand, a V-shaped section between the thumb and forefinger. A Canadian study found this technique reduces toothache pain by as much as 50 percent compared with using no ice. The nerve pathways at the base of that V stimulate an area of ​​the brain and prevents pain signals from the face and hands.

7. Eliminate the pain!
German researchers have discovered that coughing during an injection can lessen the pain of the needle stick. According to Taras Usichenko, the author studied the phenomenon ', this trick cause shock, while increasing the pressure in the chest and spinal canal, retaining structures regulating pain in the center of the spine.

8. Thaw your brain!
Too much ice cream will freeze the brain, meaning that there is a sensation of dizziness. Press tongue to palate, cover the ceiling as much as you can "Since the nerves in the roof of your mouth get extremely cold, your body thinks your brain is freezing, too, the result raises ice cream headache, "says Abo. The more pressure you do, the sooner the headache tablets reduced.

9. Overcome the desire of the most urgent!
Want to pee? No bathroom nearby? you guys?
Thinking about sex preoccupies your brain, the result you would not feel uncomfortable, says Larry Lipshultz, MD, chief of male reproductive medicine at Baylor College of Medicine.

10. Makes the heart back to normal
Trying to overcome excited? Blow your thumb. Vagus nerve, in charge of controlling the heart rate, can be controlled through breathing, says Ben Abo, an emergency medical services specialist at the University of Pittsburgh. This can make the heartbeat return to normal.   

11. Eliminating stomach cramps
If you're like most people, when run, you exhale as your left foot touches the ground. This causes downward pressure on the liver (which is located on the right), and will pull the diaphragm and cause abdominal cramps, according to Doctors Book of Home Remedies for Men. The fix: Exhale as your left foot strikes the ground.

12. Creating a stable body after drinking a lot
Too many drinks left you dizzy? Put in place a stable hand. The ear that regulates balance, the cupula, a fluid of the same density as blood. "As alcohol dilutes blood in the cupula, the cupula becomes less dense and rises, "says Dr. Schaffer. This makes the brain confused. The touch of a stable object gives a second opinion, and you can feel more balanced. Because of very sensitive nerves in the hand.


13. Eliminating tingling or numbness     
If your hand falls asleep while driving or sitting position, rock your head (odd shaking his head). Can remove less than a minute, he said. DeStefano. Numbness caused by pressure of a collection of nerves in the neck, loosen the neck muscles relieve the pressure.

14. Extend hold your breath
 If you have trouble reaching one-fourth from the bottom of the pool, take short breaths first-essentially, hyperventilate (breathe fast and deep). When in the water, not a lack of oxygen that makes you want to breathe, but the buildup of carbon dioxide, which makes your blood acidic, which signals to the brain there was something wrong, "When you hyperventilate, the influx of oxygen lowers blood acidity," says Jonathan Armbruster , Ph.D., associate professor of biology at Auburn University. "This tricks your brain into thinking it has more oxygen."At least up to 10 seconds.

15. Feel the supersonic hearing!
If you're stuck chatting up a mumbler at a cocktail party, lean in with your right ear. Right ear is better than the left ear in terms of following the rapid rhythms of conversation, according to researchers from UCLA's David Geffen School of Medicine. Conversely, if and to identify that song playing softly in the elevator, use the left ear is better at picking up music tones.

16. Impress your friends!
Next time you're at a party try this trick: Have your friend stand up, stretch the hand and palm down position, remain in this position. Then place two fingers on his wrist and push down, your friend must fight. Now make him put one foot on the higher ground a few inches (the stack of books or magazines) and repeat the above, By creating an uneven waist position, the brain that the spine is vulnerable, so stop the body's ability to dodge, Rachel Cosgrove, CSCS , owner of Results Fitness, in Santa Clarita, California.

17. Prevent nearsightedness
The distance vision is rarely caused by genetics, says Anne Barber, OD, an optometrist in Tacoma, Washington. "This is usually caused by near-point stress." In other words, staring at your computer screen for too long. Try this trick, close your eyes, tense your body, take a deep breath, after a few seconds, release your breath and muscles at the same time. Tightening and releasing muscles such as biceps muscle can make other unrelated muscles like the eyes into relaxing as well.

18. Mind Reading!
Your own! "If you're giving a speech tomorrow, repeat before going to sleep," says Candi Heimgartner, an instructor of biological sciences at the University of Idaho. Since most memory consolidation happens during sleep, anything you read before bed is more likely read as a long-term memory.
