WHY POTATO CHIPS ARE CORRUGATED OR CURVED?

Take two empty soda-Pepsi cans. You can stand on them. They will easily bear your weight, even though their walls are paper thin. The curvature of the cans gives the strength.

Take an egg. Hold in your palm. Squeeze it as far as possible. You cannot break it. But, if you make a small dent in the shell, it will break. The egg is curved on both sides (lengthwise and breadthwise). Hence it is so strong.
A curved glass-blade has strength. So it is not damaged by heavy rains.
The curves are always used in constructions to give strength to the building. Arches, Domes, entrance etc.

You might have seen 'corrugated' cardboard box. They have an undulating wave of cardboard inside their walls. They are lightweight and thin. But they are stiff enough to resist bending under considerable loads. so once again, curves mean strength. We use corrugated metal sheets, fiber sheets for the same reason.

Coming to potato chips and Pringles; they are corrugated or curved. So they will not easily break. They also give crispiness and crunchy feeling when biting. It is said that these chips are designed using computers. Remember, chips are also curved on the top side and as well as the bottom side.
Note: Take Indian chappathi or Italian pizza. When you hold it, just fold it(curve it). In this way, they will stay stable, you can easily eat them.

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
