EMBRACE YOUR FLAWS

ADVT: SMARTWATCHES IN AMAZON

We always worry about our flaws. If one's nose does not have a perfect shape, he worries a lot. But, do you know, in spite of our flaws, many people still love us.

The matchmaking site "OK Cupid" conducted one experiment. The site used a 'five-star rating' system, for attractiveness. OkCupid wanted to find out how this attractiveness score relates to the number of messages received from interested persons. So a sample of 500 women all between the age of twenty and twenty-seven and all living in the same city, was monitored over the course of a month and the data analyzed.

During the study, one "Ms.Attractive" had an average attractiveness score of 3.4 and the other Ms. Controversial had an average attractiveness score of 3.3. You would expect these two ladies to receive a similar amount of online attention, but there was actually a pretty big difference, with Ms.controversial receiving around three times more messages than Ms.Attractive.

Ms. Attractive's most common score was 4, followed by 3, etc. In general, most people thought she was reasonably attractive.

But, Ms. Controversial's most common scores were 1s and 5s. People either loved her or hated her. There was a lot of disagreement But in the world of online, the haters do not matter the lovers do, resulting in Ms. controversial having many more online messages sent her way.

The pattern is curious and the mathematics hints at something important. "embrace your flaws". Make yourself more controversial. A flaw for one person is a draw for another.

Some may like the girlish look in a boy. Some others may like the boyish look in a girl. "Beauty lies in the beholder's of the eye".

CEO of Google, Sundar Pitchai once said, "Wear your defeats, dishonor, flaws proudly. They will bring victories." If you are controversial, you are successful.

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
