WHY DO MY FRIENDS HAVE MORE FRIENDS, AND THE CURE FOR PANDEMIC

     

Join our free course-Build your personal expert with python.


                             Today, we can count friends through Facebook.  And our friends seem to have more friends. why?

    A person who does not have any friend will also not be your friend.  A person who makes friends with everyone will also make friends with you.  That is, if a man has more friends, he is more likely to make friends with you.  If he has fewer friends, he may not be your friend.  That is why those who make friends with you would already have more friends.

    Your friends will have more contacts and interactions with others.  Hence infectious diseases will easily spread through them. So your friends seem to have more illnesses than you.

    Today, we are struck by the pandemic.  The Hindu dated 24-08-2020 says, "with 3 million cases, COVID -19 unlikely to abate soon.  Only a vaccine can prevent infections and help bring out herd immunity".

     But we cannot vaccinate all the 120 crore people at once. Here 'friends of friends' theory help us.  If you have a vaccine, pass it to a good friend and ask him to pass it to his good friend.  The vaccine will move from person to person and finally land in the hands of the most popular person.  He normally has more social interactions than others.  If he is vaccinated, he will not pass the disease to others because of his popularity.  If this procedure is followed and all popular persons are vaccinated, only 30% of vaccine is enough.  That is, if 30% of the country's population is vaccinated, the country will get full herd immunity".

    The vaccinate-your-friend approach could achieve herd immunity for a fraction of the cost and this applied to everything from seasonal flew to the pandemic.

FRIENDSHIP PARADOX:

"An average number of friends is always less than the average number of friends of friends".

THE EARTH, A SUPER ORGANISM

     JOIN MY COURSE: "Become a programmer in a day with python"       A man called 'love lock' (what a name) proposed a theory called Gaia theory, named after Greek Goddess.      It says, "Earth is a self-regulating organism like a human being.  The organic life in it interacts with in-organic matter and maintains atmosphere, temperature and environment".  Hence the earth is still suitable for the life to thrive.      Imagine, in a particular place, there are lot of flowers.  Some flowers are white and some are darkly coloured.  We know, white reflects light and heat while dark absorbs the same.  White flowers can thrive in hot climate.  But dark flowers requires cold climate.  The absorption and reflection balances and the environment reaches average, warm temperature at which both the flowers can co-exist.  This is the essence of "Gaia" theory.      On our earth, ...

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.   ...

DISORDER IS THE "ORDER OF THE DAY"

         Imagine a balloon full of air.  The air molecules are moving randomly inside the balloon.  Let us pierce the balloon with a pin.  The air rushes out.  Why should not the air molecules stay inside the balloon safely and ignore the little hole?  That is not the way the world works.  The molecules always "want to occupy as many states as possible".  Hence the air goes out in the open to occupy more volume.   The things always goes into disorder (entropy) and the disorder increases with time.  The above statement is what we call "second law of thermodynamics".      Consider a cup of coffee on the table. Suppose the heat from entire room flows to your cup of coffee, the coffee will boil and the rest of the room will freeze.  Freezing means bringing things to order and arrangement.  It violates the second law.  Hence it will never happen.  Hence heat must flow from high ...
