THE STORY OF A RIVER

Featured post on IndiBlogger, the biggest community of Indian Bloggers
   

     Some where in the mountains, a river originates.  It flows down to the low-lands and into the sea.  It flows because of the slope and the gravity.  River appears to run on a plane ground.  But there is always a slight slope.

     If one of the banks of a river is weak, the river burrows in and curves.  The curved flow of water hits the opposite bank and curves again. It repeats on and on.  That is why, all the rivers follow snake like path.

     The river suddenly turns creating a whirlpool; it some times falls down creating waterfalls; it smashes on boulders and rocks; it splits up creating island; it finally enters ocean where again there is clash between land mass and waters.  Consequently river split up into several branches creating delta region.  Such a hard journey. The river's journey is similar to the human life.

     The river is like conveyor belt.  It cycles waters from ocean to clouds and back again.  All the human settlement and civilizations started on the banks of rivers.
     The electric currents flow through the wires, printed circuits and keep the gadget live and active.  Similarly, the flowing rivers keeps the all life forms active.  Hence rivers are always seen and cared with reverence.

    Man's intervention:  Man has built dams across rivers.  The reservoirs are used for storing waters without letting everything into the sea.  Power stations are built at the bottom of the dam.  When the water rushes down into the power house, it pushes and rotates huge blades which in turn rotate a coil within a magnetic field generating electric power.  Then the water flows forward to irrigate the paddy fields.

     Rivers also serves as good transport system.
     Let the rivers not run dry
     Let us not engage in water wars.

           Men may come;
           Men may go;
           I will go on forever

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 ...
