CAN YOU DRIVE A CAR LIKE JAMES BOND?

You can, if you own a new Tesla car. Bond lifts up the car side ways even up to 90 degrees and drives it on just tow wheels. He again brings the car back to normal position without toppling. It may be a screen gimmick. But today, It can be real.

First, we should understand stability. Consider 'Thanjavur doll'. It is heavy and hemispherical at the bottom. If you push the doll to one side, it will not fall down but will return and oscillate back into its original position. Why?
Center of gravity (CG) of a body is a point in the body at which all the weight of the body acts. Or, at CG, one can balance the body with a tip.
Draw a vertical line from the CG. If the line falls with in the base of the body, it will have good stability. That is, when a body is pushed to one side and the line from CG falls with in its base, the body will return to its original position. If the vertical line crosses the base, the body will topple.

To achieve this stability
1. The base of a body should be as wide as possible
2. The center of gravity must be as low as possible.
The Thanjavur toy meets both the criteria. 1. Its base is wide. 2. It carries more weight at the base. Hence CG is lowered. The line drawn from CG will never cross the base, even if you tilt the toy to 90 degrees towards floor.

In new Tesla car, heavy batteries are loaded at the bottom. Hence the CG is lowered and the stability conditions are met. You can do a 'Jame bond' with it.
When we carry heavy bucket of water in one hand, we naturally stretch the other hand. This happens to widen the base of our body and to achieve stability.

In the leaning tower of Paisa also, the line from CG falls with in its base. Hence the tower stands slantingly even today. But it should not lean further.
You can now understand why the pendulum also has the stability. But the inverted pendulum is not possible.
This principle is employed in the ships so that it can travel safely in the storm and waves.
Our buses have stability to certain extent. They can tilt up to 23 degrees. Hence over crowded buses and passengers hanging on the foot boards are not advisable.

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
