YOU HAVE A BIT OF ALAXENDER, SOCRATES, ARISTOTLE IN YOUR BODY!

Is it ? yes.
Let us say, long long ago Socrates took a cupful of water from sea-shore and washed his face. Today, you took a cupful of water from the sea near your place and washed your face. Have you used any of the water molecules that Socrates used long back? You may think the chances are highly remote. But the scientific answer is really surprising.

A little calculation: you may skip
The total mass of earth's oceans = 10ˆ18 metric ton.
or 10ˆ24 grams.
Mass of one water molecule= 3*10ˆ-23 gm.
Hence No. of molecules in the ocean = 3* 10ˆ46

Mass of water in a cup = 250 gm.
No. of water molecules in a cup =8.3*10ˆ24
No. of cups of water in the oceans = No. of molecules in the oceans/ No. of molecules in a cup
= 3* 10ˆ46/8.3*10ˆ24
= 3.6 *10ˆ21 cups
Hence No. of cups in the oceans is far less than no. of water molecules in a cup. That means, if you draw out a cupful of water from a sea, .There is high chance that It might contain some molecules used by Socrates long back

= No. of molecules in a cup/No. of cups of water in the oceans
= 8.3*10ˆ24/3.6*10ˆ21
= 2300 molecules.

That is, "every cup, we draw out from the ocean may contain 2300 molecules that is once used by Socrates( in 400 BC)
By the same argument, we can conclude that each of us might expect to be made of a considerable number of the atoms and molecules that made up Socrates or Aristotle's body.
When one's life ends, he may turn into parts of a tree, flower, fruit, tooth of a child or nail of a beautiful girl.

As long as we are alive, we are constituted by collections of various molecules that we call as "I" with ego.

We know, water is recycled; cloud, rain, river, ocean and back to cloud. The oxygen-carbon-di-oxide cycle is maintained by the animals and the plants. There is food-fertilizer cycle again through animals and plants.

Recycling is the way of the nature. We should learn and adopt from it.

LISSAJOUS FIGURES

Definition: "When a particle is subjected to two sine wave motion or two oscillatory motion at right angles, the particle describes lissajous figures". We know sine wave motion and circular motion is basically same. Hence we draw two circles A and B perpendicular to each other. The circle B rotates twice faster than circle A. That is, frequency of circle B is two times than that of A. A particle at the intersection of two circles is subjected to two sine wave motion A and B at 90 degree simultaneously. The particle will describe figures depending on the frequency and phase of A and B . In our case, the ratio of frequency is 1:2 and the two waves are in phase. To draw lissajous figures : A moving point in both the circles are chosen. Here we should remember; during the time taken by the circle A to complete one rotation, circle B completes two. Hence the points are marked on the circles according to their speed. Then straight lines

THE PARABOLA

A jet of water shooting from a hose pipe will follow a parabolic path. What is the so special about parabola. Y= x^2 Draw a graph for the above equation. It will result in a parabola. This parabola is also called unit parabola. Any equation involving square will yield a parabola. Example: Y = 2x^2 +3x+3 (also called quadratic equation) X= 2 and -2, both satisfies the equation 4 = X^2. Parabolic equations always have two solutions. Any motion taking place freely under gravity follows parabolic path. Examples: An object dropped from a moving train, A bomb dropped from flying plane, A ball kicked upwards. If a beam of light rays fall on the parabolic shaped mirror, they will be reflected and brought to focus on a point. This fact is made use of in Dish Antenna, Telescope mirrors, etc. Inverted parabola shape is used in the construction of buildings and bridges. Because the shape is able to bear more weight. A plane

CASINO'S GAME

Let us find out how the casino survives with mathematics. Say, your friend invite you for a game of dice. You must bet (wager) 2 dollars. If you roll 'six' you will get back 8 dollars. The game will go on for 30 rounds. All sounds good. The probability of rolling 'six' is 1/6. Since the game will be played for 30 times, the 'expected win' is 30*1/6 = 5. That is, you are expected to win 5 rounds out of 30. Hence your gain will be 5 * 8 =40 dollars. ok. This also implies that you will loose 25 rounds. Hence your loss will be 25*2 =50 dollars. Your net gain will be gain-less = 40-50 = -10 dollars. For 30 rounds, the loss is -10 dollars, Hence, for one round =-10/30 = -1/3 dollars. There will be a loss of -1/3 or 0.33 dollars per round. It is not a fair game. Let us make a simple formula to calculate 'Pay out per round\. The probability for a win = p The pay-out in case of win = V No. of rounds = n The expect
