WHAT IS TOMORROW'S OIL?

Long back, people burned wood to get energy. Then they found coal. Next we switched to oil. Our transport system is mainly using oil as fuel even today. One fifth of the world's oil reserve is there in the middle east countries. Oil price rise disturbed world Economy thrice.

How long we will use oil? Is there alternative? Let us try to answer.

Many countries are moving towards nuclear energy. 'Radiation' risk is present in nuclear reactors.
Wind energy, solar energy, geothermal energy are safe, clean and renewable. We are focusing on them now. Today, many trains have electric engines. We rarely see steam engines. Hybrid cars (petrol + electric) are beginning to appear. We require many charging stations on the road to fuel electric cars. First, we have to overcome this problem.

Electricity serves us everywhere as a clean energy. But the main matter is the source of electricity. It may be steam, water flow, Nuclear energy, solar power, chemical battery etc... We are still searching for efficient sources. In the transmission of electricity, there is loss due to liberation of heat. If we have zero resistance wire (super conductor), we will get zero transmission loss. But it is still a dream.

In energy sources like wood and petrol, the energy is stored in them. We can get the energy from them using a spark of fire at any moment. But transmitting their energy directly (without conversion) from one place to another is impossible.

In the case of electricity, transmission is very easy. But the storage is difficult. Today, using capacitor, super capacitor, battery, we are slowly increasing the storage capacity.

But still, oil is highly efficient fuel. Petrol bunks (gas stations) are being opened everywhere, even though the reserve is finite.
Oil (jet fuel) is still good fuel in aviation industry. It is highly power packed; cannot be replaced for now.

But we cannot underestimate the man's ingenuity. He will innovate and replace oil in the future. Necessity is the mother of invention.
In my humble opinion, tomorrow's energy economy will be mixed one. It will have renewable energy sources like, wind and solar energy; Non -renewable sources like fossil fuel (coal, oil) ; Nuclear energy and yet to find new sources of energy.

Discover, innovate, invent and live well.

Note: Some say, 'Digital data is the 'oil' of tomorrow'. Some others say, "water may get the status of oil in the future"

LISSAJOUS FIGURES

Definition: "When a particle is subjected to two sine wave motion or two oscillatory motion at right angles, the particle describes lissajous figures". We know sine wave motion and circular motion is basically same. Hence we draw two circles A and B perpendicular to each other. The circle B rotates twice faster than circle A. That is, frequency of circle B is two times than that of A. A particle at the intersection of two circles is subjected to two sine wave motion A and B at 90 degree simultaneously. The particle will describe figures depending on the frequency and phase of A and B . In our case, the ratio of frequency is 1:2 and the two waves are in phase. To draw lissajous figures : A moving point in both the circles are chosen. Here we should remember; during the time taken by the circle A to complete one rotation, circle B completes two. Hence the points are marked on the circles according to their speed. Then straight lines

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

CASINO'S GAME

Let us find out how the casino survives with mathematics. Say, your friend invite you for a game of dice. You must bet (wager) 2 dollars. If you roll 'six' you will get back 8 dollars. The game will go on for 30 rounds. All sounds good. The probability of rolling 'six' is 1/6. Since the game will be played for 30 times, the 'expected win' is 30*1/6 = 5. That is, you are expected to win 5 rounds out of 30. Hence your gain will be 5 * 8 =40 dollars. ok. This also implies that you will loose 25 rounds. Hence your loss will be 25*2 =50 dollars. Your net gain will be gain-less = 40-50 = -10 dollars. For 30 rounds, the loss is -10 dollars, Hence, for one round =-10/30 = -1/3 dollars. There will be a loss of -1/3 or 0.33 dollars per round. It is not a fair game. Let us make a simple formula to calculate 'Pay out per round\. The probability for a win = p The pay-out in case of win = V No. of rounds = n The expect
