BASIC NEEDS TODAY: SMART HOME, SMART WEARABLE AND HEALTHY FOOD

      


          It is a night 10:00 p.m.  I locked the house doors.  I checked security camera images on my smart phone.  It is all o.k.  I opened another app; switched off all the smart lights in the house and dimmed the hall-light. Then I tapped my smart watch.  It said, "you walked 7.2 km today and burned 2700 calories.  The heart-beat at the moment is 81 per minute.  The resting heart rate is 71 today".  I felt satisfied.  I switched on the "home projector".  It cast a big image on the wall of the hall.  I put on the blue-tooth head phone (I do not want to wake up others).  I begin to watch my favorite serial "Game of throne".  This is not a wild imagination but a reality in many modern Indian homes.  The technology is affordable and accessible to Indians today.

      Out of many smart wearable and devices, smart watch stands prominently today.  Let us explore it deeply so that we can appreciate and exploit the device better.

     First, let us find out how it measures the heart-rate.  At the back of the watch, there are two green LED lights and a photo cell.  When the watch is worn on the wrist, it shines the light on the skin.  Red blood readily absorbs green light.  When the heart beats (pumps out blood), there is a surge of blood flow in the veins and hence more absorption of green light.  When the heart takes 'a bit of rest'  between the beats, there is less flow and less absorption light.  This is how the watch recognizes the heart-beats.  The 'number of beats per minute' is sent to the smart-phone through blue-tooth and the phone sends the data to the internet and the company's servers.  There, the data is interpreted using algorithms(software) and the human-friendly information is sent back to the app on our smart phone.  Then a clear graphical message is displayed on the phone.

      Besides optical sensor, there is a micro accelerometer with a gyroscope which measures our walking, running steps, and sleep pattern.  There is an altimeter.  It measures the height we climbed,  be it a mountain or a staircase.  Some watches measures body temperature also and some have GPS.

      Hence the sensors collect the data and the algorithms interpret them in a user-friendly way.  From the watch and its app, we get the information like, How is the quality of our sleep; How healthy is our heart; what is heart resting-rate; How much calories we burned; How to shed weight; How active we are in a day and so on. So get a smart watch and #GetFitWithFlipkart  .

     WHO's report says, every year around 25 million people meet their end because of cardiovascular diseases.  Hence, it is a wonder, we do not still see activity band on everyone's hand.

      These words, "obesity, diabetes, physical inactivity, blood pressure, sleep patterns, lifestyle diseases",  figure in all the health-reports and articles today.  Hence we need these wearable digital monitors badly.

     Google glasses, smart shoes, smart bracelets and rings, smart clothes and bags, are going to be popular as smart watches in the future.  Surveillance smart camera hooked to the internet is a boon today.  You can watch your home and office from anywhere in the world. (There is a wireless door bell which when pressed by a person,  takes the photo of the person immediately and sends it to the phone of the owner).


      Tomorrow, all the electrical and electronic appliances in our home can be controlled remotely using apps on the phone. We have traveled a long way from stone age to the digital age.  Have a smart, healthy, long and happy digital life. Let us start #SmartHomeRevolution now.

"Swiss watch may be the icon of wealth
But a smart watch is the icon of health".

 "You may have a small home
But you can make it smart".

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
