Water is a transparent and nearly colorless chemical substance that is the main constituent of Earth’s streams, lakes, and oceans, and the fluids of most living organisms. Its chemical formula is H2O, meaning that each of its molecules contains one oxygen and two hydrogen atoms that are connected by covalent bonds. Strictly speaking, water refers to the liquid state of a substance that prevails at standard ambient temperature and pressure; but it often refers also to its solid state (ice) or its gaseous state (steam or water vapor). It also occurs in nature as snow, glaciers, ice packs and icebergs, clouds, fog, dew, aquifers, and atmospheric humidity.

Water covers 71% of the Earth’s surface.[1] It is vital for all known forms of life. On Earth, 96.5% of the planet’s crust water is found in seas and oceans, 1.7% in groundwater, 1.7% in glaciers and the ice caps of Antarctica and Greenland, a small fraction in other large water bodies, 0.001% in the air as vapor, clouds (formed of ice and liquid water suspended in air), and precipitation.[2][3] Only 2.5% of this water is freshwater, and 98.8% of that water is in ice (excepting ice in clouds) and groundwater. Less than 0.3% of all freshwater is in rivers, lakes, and the atmosphere, and an even smaller amount of the Earth’s freshwater (0.003%) is contained within biological bodies and manufactured products.[2] A greater quantity of water is found in the earth’s interior.[4]

Padmini, also known as Padmavati, was a legendary 13th–14th century Indian queen (Rani). Several 16th-century texts mention her, of which the earliest source is Padmavat, an epic fictionalized poem written by Malik Muhammad Jayasi in 1540 CE. The Jayasi text describes her story as follows: Padmavati was an exceptionally beautiful princess of the Singhal kingdom (Sri Lanka). Ratan Sen, the Rajput ruler of Chittor Fort, heard about her beauty from a talking parrot named Hiraman. After an adventurous quest, he won her hand in marriage and brought her to ChittorAlauddin Khalji, the Sultan of Delhi, also heard about her beauty, and laid siege to Chittor to obtain her. Many events occurred during the period of the siege, till the fort was finally taken. Meanwhile, Ratan Sen was killed in a duel with Devpal, the king of Kumbhalner, who was also enamoured with Padmavati’s beauty. Before Alauddin Khalji could capture Chittor, Padmavati and her companions committed Jauhar (self-immolation) to protect their honour. After her sacrifice, the Rajput men died fighting on the battlefield.

Many other written and  tradition versions of her life exist in Hindu and Jain traditions. These versions differ from the Sufi poet Jayasi’s version. For example, Rani Padmani’s husband Ratan Sen dies fighting the siege of Alauddin Khalji, and thereafter she leads a jauhar. In these versions, she is characterised as a Hindu Rajput queen, who defended her honour against a Muslim invader. Over the years, she came to be seen as a historical figure, and appeared in several novels, plays, television serials and movies. However, while Khalji’s siege of Chittor in 1303 CE is a historical event, many modern historians question the authenticity of the Padmini legends.

The “center of mass” of any object can be thought of as the average location of all of the mass in that object. For a simple object like a meter stick, the center of mass works out to be just the center of the object (i.e. the center of the stick at the 50cm marker). If you took a meter stick and put a big lump of clay at one end to make it heavier, then the center of mass would be closer to the heavier end.

A related concept is that of the “center of gravity”. If you add up all the effects of gravity pulling on every part of an object, it appears to pull the center of gravity straight down. In almost all cases you are likely to encounter, the center of mass and the center of gravity are the same. (The only times this wont be true is if you are sty dying objects that are so large that the gravitational field due to the earth is not constant over the object, like for example the moon).

The concept of “center of mass” in the form of the center of gravity was first introduced by the ancient Greek physicist, mathematician, and engineer Archimedes of Syracuse. He worked with simplified assumptions about gravity that amount to a uniform field, thus arriving at the mathematical properties of what we now call the center of mass. Archimedes showed that the torque exerted on a lever by weights resting at various points along the lever is the same as what it would be if all of the weights were moved to a single point—their center of mass. In work on floating bodies he demonstrated that the orientation of a floating object is the one that makes its center of mass as low as possible. He developed mathematical techniques for finding the centers of mass of objects of uniform density of various well-defined shapes.[1]

Later mathematicians who developed the theory of the center of mass include Pappus of Alexandria Ubaldi,Federico Commandino,[3] Simon Stevin,Luca ValerioJean-Charles de la FailleJohn WallisLouis CarréPierre Varignon, and Alexis Clairaut.

Newton’s second law is reformulated with respect to the center of mass in Euler’s first law.

In physics, the center of mass of a distribution of mass in space is the unique point where the weighted relative positionof the distributed mass sums to zero, or the point where if a force is applied it moves in the direction of the force without rotating. The distribution of mass is balanced around the center of mass and the average of the weighted position coordinates of the distributed mass defines its coordinates. Calculations in mechanics are often simplified when formulated with respect to the center of mass. It is a hypothetical point where entire mass of an object may be assumed to be concentrated to visualise its motion. In other words, the center of mass is the particle equivalent of a given object for application of Newton’s laws of motion.

In the case of a single rigid body, the center of mass is fixed in relation to the body, and if the body has uniform density, it will be located at the centroid. The center of mass may be located outside the physical body, as is sometimes the case for hollow or open-shaped objects, such as a horseshoe. In the case of a distribution of separate bodies, such as the planets of the Solar System, the center of mass may not correspond to the position of any individual member of the system.

The center of mass is a useful reference point for calculations in mechanics that involve masses distributed in space, such as the linear and angular momentum of planetary bodies and rigid body dynamics. In orbital mechanics, the equations of motion of planets are formulated as point masses located at the centers of mass. The center of mass frame is an inertial frame in which the center of mass of a system is at rest with respect to the origin of the coordinate system.

the best journey of my life was when I  was in chennai for a  trips .My aunt

There is nothing better than the emotions and feelings one can receive from setting out on an adventure. Journeys help us to forget about our everyday issues. That is why I want to tell you about the best journey of my life.

It started at home as I began to pack items for a journey. I was excited because my parents and I were going to Thailand: the most interesting place to me. I could not imagine what it would be like.

The first experience we had when we got out of the plane to enter Thailand was the tropical, wet, hot air that permeated the environment. We arrived at our hotel on the south of Phuket Island. Beauty seemed to be all around us. From the one side of the road there was a lush greenery of tropical forest, from the other there were turquoise waves of the Andaman Sea.

We decided to spend our first days on a cozy seacoast and take a rest from a tiresome trip. The weather was wonderful. The sun was shining and the water was so warm, placid and limpid that we could see our shadows in it. I had the impression nothing else existed in this world besides us, nor the cares of everyday life nor urban fuss. We were enjoying every minute of our rest, slowly sipping a coconut milk through a tube straight out of a coconut. The days were changing from one another with new, bright, unforgettable emotions and impressions.

We wanted to pass one day away on motorbikes, studying the island. Our trip took a whole day and we managed to bike the half of the island riding along the coast. The views we saw on our journey showed us another side of local life. People were in a hurry going to work or other attending other business. The traffic in Thailand is extremely busy and noisy. A lot of people ride motorbikes, which is a distinguishing feature of Thailand.

All the way long, we made breaks to taste the delicacies of the local cuisine in snack bars. I enjoyed Thai food immensely with its extraordinary combination of sweet, sour, and spicy flavors. Sometimes the dishes were so spicy, that tears streamed from my eyes.

We also decided to diversify a bit, and go to less touristic parts of the island. Our island was covered by steep hills. The picturesque view of the tropical jungles and endless spaces of the sea with many adjoining islands, the beauty and splendor of local nature was opened to us. I was overfilled with the sense of infinite freedom and peace of mind. There was the impression that nothing is necessary in life except this place and moment.

It was a truly sad realization when we knew we had to travel back home. The whirlwind of emotions and feelings swept over my mind: this is completely another world, with its climate, people, food, traditions, and customs that charm and dip you in the extraordinary atmosphere of calmness and composure. I remember it now with freshness and understand that it was the best journey of my life.
