MAGNIFICENT THREE

We are going to see some important phenomena which utilizes only THREE entities.

Only using three particles namely proton, neutron and electron, all atoms, molecules, cells and matter are built. Protons and neutrons are responsible for mass. Proton and electron carry positive and negative charges. Electron is responsible for electromagnetic property of the element and also interact with other atoms and molecules. Hence these three particles are the required minimum to build the entire world . Hence 20 particles does not exist in the atom.

Only four chemicals(cytosine [C], guanine [G], adenine [A] or thymine [T]) are used to write the entire bio-information of a species in the DNA molecules. Here only three letter (chemicals) words are used to indicate the amino acids which are building blocks of life.

We live in three dimensional world.and we are three dimensional being. Even we find it difficult to navigate in the two dimensional surface of the earth. We require GPS, compass, google map etc. If this world gets more than three dimension, only confusion may result. If we are two dimensional being like a piece of paper, life may not function. That is, metabolism, respiration, thinking etc. may not happen. Hence three dimension is the required minimum for a good life.

Red, Green, and blue. Three primary colours are enough to produce all the millions of colours and arts. By suitably combining them, we can produce any colour. Because our eyes are designed for these three colours.

There are only three fundamental forces. 1. gravitational force 2. electromagnetic force 3. strong and weak nuclear force. The universe, our world, all machines and we function only because of these forces. More forces cannot co exist.

Solid, liquid and gas. only three phases of matter. Conversion between them is easy with absorption or release of heat energy. Our earth has solid core, liquid surface, gas cover(atmosphere).

To conclude; A minimum no. of entities (here, three) in each category is enough to produce variety, spice, colour, life. Man made machines and God made artifacts. Less number. of 'things' means more clarity, good harmony and no surplus.

A principle called occam razor says, "Entities should not be multiplied unnecessarily"

It can be interpreted in many ways. We will take it as "Minimum number of entities are enough to produce varied and complex structures and phenomena".

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
