Kepler's Laws of Planetary Motion

Kepler was a German mathematician and astronomer. He studied the motion of planets and discovered these 3 laws .



Kepler's First law :


It is also called as The Law of Orbits. It states that the orbit of every planet is an ellipse with the sun at one of the foci.



Kepler's Second law :


It is also called as The Law of Areas. It states that a line joining a planet and the sun sweeps out equal areas during equal intervals of time as the planet travels along its orbit. Hence a planet travels faster while close to the sun and slows down when it is farther from the sun.



Kepler's Third Law :


It is also called as The Law of Periods. It states that the square of the period of any planet is proportional to the cube of the semimajor axis of its orbit.

All that u need to know abt TEA

Tea is a versatile low-calorie beverage that aids growth, digestion and vitality..keeps the body beauiful, glowing and full of life. It is a beverage made by steeping processed leaves, buds, or twigs of the tea bush, Camellia sinensis, in hot water for a few minutes. The processing can include oxidation, heating, drying, and the addition of other herbs, flowers, spices, and fruits. The four basic types of true tea are (in order from most to least processed): black tea, oolong tea, green tea, and white tea.


Tea is mostly grown in the sub-tropical regions in Asia. Today, there are almost 30 tea producing countries with black tea the greatest yield. Oolong and jasmine tea are also very popular but green tea has the smallest yield.

Black Tea
Black tea is fully fermented, and gains its color and character from the processing of the leaves. Once picked, the leaves undergo a series of five steps, called the "Fermentation Process".
Black tea is grown in China, India, Sri Lanka, and Africa, and is the most common type of tea in the western world. The leaves range in color from brown to black, often with golden or silver tips. The bright copper liquor has a full, round aroma, and a flavor ranging from malty to flowery. This is the only type of tea that can be taken with milk and sugar.

Oolong Tea
Oolong is a semi-fermented tea. It undergoes the same treatment as black tea, but instead of rolling the entire leaf, only the edges of each leaf are rubbed. The result is that only the cells at the edges of the leaves are disrupted and will ferment. Additionally, oolong teas are fermented for less time than black teas.
There are two main types of oolong: one grown in China, and the other grown in Taiwan (Formosa). China oolong, fermented only 12-20%, has a distinct fresh taste, and produces a pale yellow liquor. Formosa oolong on the other hand, is usually 60% fermented, and is known for its golden liquor and exquisite flowery aroma.
Oolong is especially good for digestion, so is naturally a great tea to drink after a large meal. It should never be drunk with milk or sugar or lemon.

Green Tea
Green tea is unfermented. After the leaves are picked, they are immediately pan-fired or steamed to prevent any oxidation. They are then rolled, dried and sorted. Green tea has a more subtle, delicate flavor, and far less caffeine than fermented tea. It is said to be medicinally beneficial, because the unfermented leaves retain a higher concentration of natural vitamins and polyphenols than their fermented counterparts. Green tea contains minerals (iron, sodium, potassium) and an assortment of vitamins (carotene, A, D, B1, B2, C).
Green tea is grown mainly in China, Taiwan and Japan. China green tea is known for its mild and subtle taste, refreshing aroma, and pale hues. The leaves range in appearance from silver to deep emerald. Japanese tealeaves are often brilliant green, reminiscent of the lush gardens they are grown in. They produce liquor that ranges from jade green to light yellow, with a fragrant puckery and slightly sweet taste. Japan only produces green tea and has perfected the harvesting techniques. The Japanese government subjects all tea for export to rigorous inspection and checks the leaves, stems, moisture, content, flavor, taste and color. Tests are also undertaken to determine tannin, caffeine, vitamin and mineral contents.
Green teas should be enjoyed in their pure form, without milk or sugar.
The key point in tea quality is the production. The tea garden's reputation is based on their ability to preserve the natural quality of the leaves. Traditionally (and still today for the highest grades), tea manufacturing was undertaken manually. Today, most high-production tea gardens employ machines. One garden's processing will yield characteristic appearance, bouquet and flavor panels.

White Tea
White tea is tea manufactured by a process that uses relatively low heat and no rolling. The formative stage is an extended period of withering, during which enzymatic reactions progress under the right temperature, humidity and airflow. The key is to get the fresh leaves to mature properly with minimal oxidation.[1] White tea usually contains buds and young tea leaves, which have been found to contain lower levels of caffeine than older leaves, suggesting that the caffeine content of some white teas may be slightly lower than that of green teas


India has 3 main places where exceptional tea is grown -

Assam is indigenous tea plants of India. A full flavor, very satisfying tea. Assam teas are strong, well rounded and malty with rich aroma and flavor. Usually served with milk and sugar.

Darjeeling at 6,000 feet above sea level, boasts at least 68 tea gardens. This tea is the best in the world due to its perfect growing conditions: cool, moist climate, high altitude, sufficient rainfall, well drained sloping landscape, and soil rich in minerals.. This tea has a delicate and superior flavor. I call it the rejuvenating tea or the spa tea because of its fine taste.

Nilgiri is similar to Ceylon teas grown in nearby Sri Lanka. A full bodied tea with an excellent fragrance and flavor


Types of Indian teas

Black Tea : This is what most westerners would think of when they hear the word tea. Black tea undergoes a fermentation process as part of production. We carry the best Darjeeling black tea in the world in our store.
Green Tea : This is what is commonly known as tea in Asia. Green teas are unfermented. We carry the best Darjeeling green tea in the world in our store.
Oolong Tea : These teas are half way between green and black teas. They undergo a short fermentation process and so are often known as semi-fermented teas. We carry the best Darjeeling Oolong tea in the world in our store.
Masala Chai : A typical Indian variety. Aromatic masalas are added to loose tea to make spiced Chai, and this has been the Indian drink of choice for hundreds of years. It is a perfect blend of freshly ground spices (masala) like cloves, cinnamon, nutmeg, ginger, cardamom and pepper, added to a boiling pot of loose leaf tea and milk to make a delicious, satisfying and healthy beverage.
