WHY THE MOVIE IS SHRINKED IN TV AND MOBILE

Take an A4 paper. Measure length and breadth. It will be 297 mm and 210 mm. 297/210 gives 1.414. This is the square root of 2. We can also say, the A4 paper has the ratio 1:1.414. For any A series paper, we always get this ratio. We know, if you cut the A4 paper into halves, we get two A5 papers. If you double -up the A4 paper, we get an A3 paper. This is the concept of A series paper.

Why should we maintain a fixed ratio? Suppose you want to photocopy the contents in the A1 paper to A5 paper using Xerox machine. The contents will exactly fit in the small A5 page. This is because of the constant ratio of A series papers. If we do not maintain the ratio, the contents will either over-fit or underfit. That is, either some contents will be left out or blank space will appear.

When a movie is telecast in the TV or streamed in the mobile, a black space appears at the top and bottom of the screen. It is because of mismatch of ratios. Mobile and TV screens have an aspect ratio of 16:9. But a movie is shot in the aspect ratio of 2.35:1. That is the reason.

Tele serials are shot in the ratio 16:9. Hence they are clearly displayed on the screen. In the case of picture and movie, landscape and rectangle always have the appeal.

Old TV had the ratio 4:3 or 16:10. 16/10 gives 1.6 which is the golden ratio given by Fibonacci sequence.

Note: All the countries have flag and flag-code. The flag-code specifies the aspect ratio. Many countries and India have the ratio 3:2 and standard sizes. A national flag should strictly adhere to the ratio and the code.

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 ...
