IS THE TEACHER REQUIRED IN THE TIME OF GOOGLE?


CLASS V
Student A :  What is the boiling point of water?
Teacher:      100 degree c is said to be the boiling point of water.
Student A:   Why 100 degree c ?
Teacher:  At 100 degree c , water bubbles up and evaporates.
Student A:  O.K.

CLASS X
Student B:  What is really happening at the boiling point?
Teacher:  Liquid water changes into gaseous state.  At the boiling point, the water molecules gains enough energy to flight the air molecules and escapes into the atmosphere.  Hence at 100 degree c, the water vapour pressure and the atmospheric pressure equals.

CLASS XII
 Student C:  What you mean by 'liquid changes into gas'?
Teacher:  The water molecules has positive end and the negative end.  The positive side of one molecule attracts negative side of another molecule.  Hence the water molecules cling together as a drop, as a liquid.  As the temperature increases, the molecules gains energy and break free from the electrostatic bonds.  The free molecules bubbles up; form vapour and than escapes into atmosphere as water gas.

    In a pharmacy, all medicines are available in plenty.  Vast medical information are also available in the internet.  Can we treat ourselves? We know, it is dangerous.  An educated, experienced doctor is required.  A teacher like doctor should give a student the required info. in right quantity at the right time.
     Teacher motivates the students for learning.  Innovation is his hall mark.  The aids, examples, experiments and narration must be interesting and innovative.  The teacher diagnose errors and mistakes and corrects them.
     Online courses, tests, training are available in plenty.  They may compliment the teachers and cannot replace the teachers.  One cannot learn engineering, medicine, car driving and swimming online.  But online courses are a boon to improve knowledge and gain multiple skills.
     Young students definitely require teachers.  But mature students may do without them.
     Teacher has one thing called 'experience' which the machine lacks.  Teacher can enforce discipline, the machine cannot.  The machine is able to value objective type test and answers (multiple choice).  But it is not able to value subjective or descriptive answers still.
     The computer cannot pat or pull up a student but a teacher can.
     "Teacher is the friend, philosopher, guide, dispenser of knowledge, father   ....".
    "A poor teacher complains,
     An average teacher explains
     A good teacher teaches
     A great teacher inspires".

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 oxygen constitute 20% of the atmosphere.  The oxygen level is always mai

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

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 temperature to low temperature and not the other way.        The air molecules in y
