YOU ARE BURNING LIKE A CANDLE-24X7

The candle, a stick of wax (oil) burns with oxygen and produce CO2 and water. Also gives out light and heat energy.

We take in carbs (carbohydrates), oil, fat. They are converted into glucose in our body. We also inhale oxygen. The glucose burns (reacts) with oxygen and yield CO2 which we exhale out; water which the body eliminates. In this process also, the energy in the forms of heat, invisible light is released. The body uses this energy for its functioning. Here the invisible light is infra-red radiation. Our body continuously emit IR waves. That is why, we and animals can be detected using infra red cameras and binoculars even in the dark night. Also our body is warm and above the room temperature always.

Medical science says the vital parameters of our body are 1. Temperature 2. oxygen level 3. Heart pulse rate 4. Blood pressure. Now we are able to understand, why they are vitals.

A dancer glow more with IR radiation because she work vigorously and also burn the food vigorously.

An average adult uses 2000 calories of energy daily. Hence we should plan our intake of food around 2000 calories. If we take more food than required, the sugars and carbs are converted into fat and stored as a reserve for future. Hence our body weight goes up.

This is the food-rich world. We are facing the problem of plenty. We come across special occasions like wedding frequently. We are offered sumptuous dinner every now and then. In a mall, there is not a single food item without sugars.
Hence the responsibility is on us. Watch and measure what you take in. Do not hesitate to say "No' to extra food.
Lead a long and healthy life.

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
