HEALTHY AND LONG LIFE IS A FEW EQUATIONS AWAY

     We all know 'bot-belly' is not good for us.  How much life we will lose because of big belly?  Here math-(a little) comes into play. 

     First, we have to find waist to height ratio -r.  Suppose your height is 172 cm and your waist perimeter are 96 cm. The ratio is 96/172=0.56.  You can have the ratio up to 0.5.  More than 0.5 is not good.  That is your waist circumference should not exceed half of your height-both for men and women. 
    Suppose you are 30-year-old nonsmoking male.  You can calculate the 'years of life that will be lost' using the equation given below. 


Years lost -y = 616.67r^3 - 920r^2 + 467.81r - 81. 
r-waist to height ratio. 


     It is a ugly polynomial equation.  We have similar equations for male aged 50 and 70; for female aged 30, 50 and 70.  I do not want to give all of them here and threaten you.  But all the six equations give a nice family of curves.  They are given below. 

 

CONCLUSIONS FROM THE CURVES 
1. Men lose more years of life than woman for the same ratio r. 
2. More years of life lost when ratio increases from an already higher number. 
3. The effect of ratio on 'years lost' diminishes with age. 
4. Ratio of 0.5 minimizes years of life lost. 
    How to increase your life span.  You have to reduce waist size.  But do not go for liposuction.  You have to reduce the belly fat through better nutrition and exercise.  Hence go for, low carb high protein, high fiber, good fat and low energy density foods.


  How to use the equations, if your age is other than 30, 50, and 70 
For male ?


Age 30: Years lost =616.67r^3 - 920r^2 + 467.83r-81  -----1 
Age 50: Y = 183.33r^3 - 180r^2 +45.167r-0.5 ------2. 
Age 70: Y = -83.33r^3 +245r^2 -188.67r+43.5------3. 
For female: 
Age 30: Y =150r^3 -175r^2 +69r-9.4  ---4 
Age 50: Y= 116.67r^3 -130r^2 +48.33r-6.4 ---5 
Age 70: Y = 60r^2 -58.4r+14.21 ----6 


   If you are non-smoking male aged 40, take equation 1 and 2; multiply the result of each equation by the factor 0.5 (since the age 40 is half-way between age 30 and 50 ); add the two answers; you will get loss of years (if any) 
Y = 0.5 * (1) +0.5(2) 
Using the above logic, a person of any age (above30) can find his loss of years life. 


    The above equations are arrived at using massive patient's data and curve fitting techniques. 
    Let us add years to our life using math.

    Nice way to quantify years of living based on belly size.

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
