Why did Archimedes shout "Eureka"?

                     Why did Archimedes shout "Eureka"?

Archimedes

The Ancient Greek scientist was trying to find a way of determining whether a crown was made of pure gold. While pondering the problem Archimedes climbed into his bath and saw the water level rise. He realized that he could compare the volume of gold in the crown with a lump of pure gold  of the same weight by submerging them and comparing the rise in water level. He leap out of his bath and cried "Eureka!" ("I have found it!")

Wonderful Waterfalls

                                                Wonderful Waterfalls

On its downhill, hurried journey towards the sea, a river flows through several different landscapes. It rushes over rocks, meanders through meadows, twists and turn through forests and cliffs before finding its way to the sea. When the river arrives at the edge of a cliff or on the side of a mountain, Its flow is abruptly interrupted. Unable to halt at the edge of a cliff or on the side of a mountain, the roaring river tumbles over the edge and plunges down the side of the mountain like a raging torrent.

The result is one of the most dramatic spectacles of nature- a waterfall!

Our loving Blue Planet is splashed with several breathtaking waterfalls. Some noteworthy waterfalls are:

                           Angel Falls

In the isolated jungles of the mountainous Canaima National Park in Venezuela, the Churun thunders down the top of a flat-topped plateau, creating the world's tallest waterfall - the Angel Falls. This awe-inspiring waterfall is 979 meters high - so tall that even before it spills into the canyon below, much of its water is turned into mist! Salto Angel, as the waterfall is known throughout South America, is more than nineteen times taller than the Niagara Falls in North America.

                          Niagara Falls

The voluminous Niagara Falls, on the Niagara River, straddles the international border between the Canadian province of Ontario and the state of New York in the USA. It is the most visited waterfall in the world and the most powerful waterfall in North America.

                           

                             GullFoss

Gullfoss is one of Iceland's most beautiful and most popular waterfall. Gullfoss is formed when the Hvita River plunges thirty-two meters into a sixty feet wide ravine(a narrow, deep valley with very steep side). Its Icelandic name, translated as 'Golden Falls' in English, is a reference to the bright rainbows frequently seen in the mist above the waterfall on sunny days. It is one of the largest waterfalls in Europe.

How to : Sing like a superstar

                                           How to : Sing like a superstar

   Everyone like to sing. So here are some tips to sing a song .

Before you even start singing it is important to relax and stand with your feet shoulder width apart. Then  Breathing properly is crucial. Learn to inhale from the belly(stomach) up. When you exhale, let the air come out rather than forcing it - imagine there is a candle in front of you and you are trying not to blow it down. Then Once you have been chosen a song you love (or something you have written) try to sing by making the sound resonate(To make a loud clear sound) form your cheeks and the roof or your mouth. Then Practice makes perfect. Do this by standing in front of a mirror and try not to laugh at the faces you find yourself pulling as you sing. Soon you will be performing in front of thousands of adoring fans.

How do musicians know what notes to play?

                  How do musicians know what notes to play?

When composing a piece of music , the composer writes down all the notes that each of the instruments will play - this is know as the score. The way the notes are written down indicates how high or low, fast or slow they should be played. Special instructions in Italian give the players more information.

                         .....  Some thing interesting ....

In the past, people made drums, rattles, and whistles out of wood, seeds and animal hide. Simple flutes have been found that are between 22,000 and 35,000 years old. They were made by boring(to make a hole in something hard with a tool) series of holes into a hollow animal bone and blowing down it.

How do we measure time?

 

By observing the Earth’s movements relative to the Sun. One complete spin of the Earth on its axis takes a day. Approximately 365.26 spin (days) make one complete revolution of the sun, or one solar year. Units of time smaller than a day, such as hours, minutes, and seconds, are measured using clocks. Weeks, months, and years, are measured using calendars. Time to know and find out more........

If everyone in the world set their clocks to the same time, when it was midnight it would be daylight in one part of the world and the middle of the night in another. To avoid this, Earth is divided into time zones.....

Time zones are generally follow lines of longitude (imaginary lines running from pole to pole), but usually bend to include entire countries or states in one time zone.

There are 24 time zones, each 15⁰ of longitude and one hour apart.

India straddles more than one time zone but has chosen a time halfway between those on either side so that the whole country can use one time.

Russia has 11 time zones – more than any other country.

China stretches across four time zones but uses only one time.

The International Date Line dividing one day from the next follows the 180⁰ meridian (longitude line) on the globe.

Countries east of the date line are a day ahead of those to the west.

The International Date Line runs mostly through the ocean, but where it would pass through or near land it bends to avoid dividing a region into two days.

1.       First demonstrated in February 2008, the world’s most accurate clock uses strontium atoms and is accurate to one second in 200 million years.

2.       The Colgate Clock in Jersey City, USA, has a diameter of 15.24m (50ft) and is the world’s largest clock.

3.       The tallest clock tower in 239.9m (789ft) high and tops the NTT DoCoMo Yoyogi Building in Tokyo, Japan.
