Paradise ........

Our Earth is the 5 th largest planet in the solar system ....Though it is considered to be younger than other planets , it is still about 4.6 billion years old.....most of its early history has been erased by natural disaters , geographic erosions and tectonic processes .......the oldest fossil of living animal found is about 3.9 billion years old........Earth is the only planet known to harbor life in the solar system.......Is'ntit amazing .....it has all the necessary ingredients to support life.....71% of Earth's surface is coverd with water and it is perhaps the only planet where water can exist in liquid form on the surface...........its atmosphere has about 77% of nitrogen and 21% of oxygen.....thus making earth a perfect place for life...... There is a layer of Carbon di oxide in the earth's atmosphere that traps the solar heat and keeps earth warm enough for us.......this is called the Greenhouse effect . Without this, the temperature of the earth would have been much much lower and oceans would have frozen , making life impossible.........................................the biological processes required to continue life on earth is due to the presence of oxygen.....without it there would be no life on earth........ Our planet's rapid spin and molten nickel-iron core give rise to an extensive magnetic field . This field and the atmosphere, protects us from all of the harmful radiation coming from the Sun and other stars. Earth's atmosphere also acts a shield against meteors, most of which burn up before they can strike the earth's surface. Thus whoever has created our planet has blessed us with not just another solar body , but has gifted us our paradise .............We all share the same sun , breathe in the same air , wear the same coat of atmosphere and enjoy every essence of life....... Astronauts who have gone to the space and have seen our planet from the atmosphere are spellbound by its beauty .................................................................
Here are some of their quotes :-

My view of our planet was a glimpse of divinity.
- Edgar Mitchell, USA

A Chinese tale tells of some men sent to harm a young girl who, upon seeing her beauty, become her protectors rather than her violators. That's how I felt seeing the Earth for the first time. "I could not help but love and cherish her.
- Taylor Wang, China/USA

The Earth reminded us of a Christmas tree ornament hanging in the blackness of space. As we got farther and farther away it diminished in size. Finally it shrank to the size of a marble, the most beautiful marble you can imagine. That beautiful, warm, living object looked so fragile, so delicate, that if you touched it with a finger it would crumble and fall apart. Seeing this has to change a man, has to make a man appreciate the creation of God and the love of God.
- James Irwin, USA

So friends let all of us take care of our mother earth .......
lets not just scribble a small line on its maginificant surface , fight over it and ravage her divinity......
lets us take a vow to save our paradise...............

Cashing in on Mathematics :

Roulette , the most popular game of casinos around the world is nothing but just a game of probability.

Well what to do in the long weekend ? “Lets go to a casino and make some money ……” But do you know that the game of Roulette is designed in a way that guarantees the casino to win even if they do not win repeatedly…..well that’s how the game has been constructed….

lemme give you a simple example ……
Remember the roulette wheel….. It is divided into 38 numbered slots.
Green -2
Red -18
Black-18
Point 1 : Whenever the ball lands in 1 of those green slots, the house wins everything that was bet on that round.
Point 2 : Suppose you bet that the ball will land in red slot (or black slot). This is the safest possible bet in roulette, since the chances of you winning the game will be 18 out of 38 . But donot forget that at the same time the chances of you losing it will be 20 out of 38 ……
So for a shorter period of time …you might beat the odds and make some money ..but in the long run its always the casino that wins ….The Theory of Probability guarantees it …….So friends , always remember that a good soldier should know when to retreat ….this applies to all aspects of life …So next time, when betting on a Roulette table try not to forget this ………………

Facts about ourselves :

1. It takes 10 million of ATP molecules per second to power an active muscle cell...

2. Without the greenhouse effect of the atmosphere , the average temperature of our planet would be about 18 degrees Fahrenheit colder......

3. Every 4 years , the world population increases by the population equivalent of United States.....

4. Every year , humans destroy an area of Tropical Rain Forest equal to the size of West Virginia...

5. The DNA of any two people of same sex is 99.9% identical.....

Can u find ????????

1.Can you find the 10 th no. of this series ......

1, 2, 5, 10 , 17 ,................

Ans. : 82

Hint : ( it goes like this : 1st : 0^2 +1

2nd : 1^2+1 ...........................n th term :(n-1)^2+1 )

2. How do you switch the values of 2 variables , generally with the help of a third ......

For example : A=2 , B=3 ...and to swap them ....get a variable C

C<- A

A<-B

B<-C

and A has B' s value , B has A's value.........

So can you do the same switch without C ????????????

Hint : A=A+B

B=A-B

A=A-B

Facts :

We all know that the famous Ancient Greek Mathematician Pythagoras was the first person to prove the very famous Pythagorean Theorem named after the master himself , which states that the square of the hypotenuse of any triangle is equal to sum of the squares of the other two sides ..............but did you know that this great Mathematician was also one of the founders of music .....................He and his disciples found , for the first time that vibrating strings produce harmonious tones when the ratios of the lengths of the strings were altered by whole numbers.....Thus they invented the first Musical Instument on Earth !!!!!!!!! Is'int it amazing !!!!!!!!!!!
