THE MATHEMATICAL BEAUTY

1. E = m*c^2 for physics
e^i*pi + 1 = 0 for math
The most important, useful and beautiful formula.

2. e = 2.71... Euler's constant.
i = Root of (-1)
pi = 3.14....
0,1 = integers.
The formula relates all the important five constants in mathematics . Note that all the constants lie around zero.

3. i is the imaginary number and used in complex algebra. Pi is connected with circle and hence belongs to geometry. e is a exponential function. It is also the base of natural logarithm . 0,1 are integers --Arithmetic
Hence the formula connects four diverse fields.

4. The formula also uses three important mathematical operations.
1. Addition (reverse is subtraction)
2. Multiplication (reverse-division)
3. exponentiation (reverse-root)

5. Meaning - little math
e^i*pi +1= 0
e^i*pi = -1
can be written as
e^i*pi = cos pi +i*sin pi = -1
-1 + 0 = -1
-1 = -1
Hence proved.

6. It brings the complex trigonometry to easy algebra (a worm hole of math)
Note: e^i*x = cos x + i*sin x

7. It represents a unit circle in polar coordinates.

8. Fourier transform works easily because of this function. It splits any wave into its sine wave and cosine wave components.

9. Quantum theory says that the sub atomic particles behave like waves. These waves are easily represented by this formula.

10. It is said: Aliens create crop circles. What they are trying to tell? People are always trying to find mystic meanings for this formula.

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
