EVERYTHING WILL BE FREE AND ABUNDANT IN 2076

In this information era, many things have become cheaper and almost free. Access to movies, music, books, magazines, articles, information have become cheaper. Publishing and distribution of all the above have become free.

Voice calls and data are getting cheaper by the day. Remember the "telegram" days when we paid for each word to be sent. Now sending even video is free.

Mails are free. Storage for our documents are free. Creating tools like photo editor, video editor, drawing tools, music creators, blog tools etc, are free.

Today we have 3D printer in which molten plastic is used to mould objects of our choice. Plastic comb, footwear and a pet house have already been fabricated.

Experts forecast: In future we will have what is called "molecular assembler" controlled by a computer. It can fabricate food, drugs, cloths, tools etc., in your home itself. You can get anything on demand and further they will be cheaper. So we may move into the future of abundance and scarce free age.

Our economy is based on scarcity. It is driven by demand and supply. This scarce free era will have a great impact on economy. The meaning of money will attain in new dimensions.

Few years back, we paid thousands for new telephone connections and hundreds for the calls. To day they are almost free. We are now buying medicines for thousands. Tomorrow we may make our own medicines in our homes using cheap basic raw materials.

We do not know what the future has in store. Hence we should always be humble.

"Time, tide and change will wait for no man".

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
