WHY DO NOT ANIMALS HAVE WHEELS INSTEAD OF LEGS?

    

ADVT: SMART DOOR LOCK FROM AMAZON

   We will explore circles and wheels in a new angle in this article.  We know wheels and circles are everywhere.  The wheel is highly useful as a 'moving device'.
     In an artificial world, we find wheels everywhere.  If they are so efficient, why does not nature use it?  But all animals have legs, not wheels. The most likely reason is that wheels need axles; if wheels were part of the animal's body; the animals would need axles too.  These axles would have to carry the sinews and blood vessels and after a couple of rotations, they would become horribly twisted.  Hence the wheel and axle are impossible biologically.

    If you drag any object on the floor, it will be difficult and will consume a lot of energy.  But if you roll anything (a wheel), the surface of contact is minimum; the surface of contact remains stationary at a moment.  Friction is greatly reduced.  Hence the wheel rolls easily consuming less energy.


    The circle contains the largest area for a given perimeter.  The sphere contains the largest volume for a given surface area.  So, the water drops, fruits pebbles are spherical.
    If the circle is highly efficient, honeycomb should contain circular cells.  But it does not, why?  If you stack cylinders, spheres, and circles, one over the other, row after row, there will be a lot of gaps, and space is wasted.  Efficient packing and strength are important qualities in nature, and no more so than in a beehive.  Bees can use square cells.  But they are not as efficient as a circle. The hexagon shape is closer to circle and also they fit properly with each other without leaving any gaps.  Hence bees (nature) has selected hexagon instead of a square or a circle.

      The hexagon is the highest order of polygon that can be used to tile a floor without leaving any gaps.
    Oscillations and waves have the repetition of motion like circular motion.  Hence the properties of the circle can be applied to them.  Nature's constant pi=3.14...plays a key role in all these shapes.

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
