REINVENTING THE ADDRESS

When we approach a bank for a loan , the first question thrown at us is "where do you live? How long you have been living in that address?" We require address for passport, ID card, driving license and for many other documents. Without address we do not exist.

We have been following the following system of address for very many years.

Door no, street,
local area, land mark,
city,
postal code.

This system of address is called S42 address standard.

In spite of your perfect address, how many phone calls you received from couriers, friends, and strangers to locate you. Does our address system 100% perfect? It seems no.

Last mile delivery is affected due to inadequacy in the address. Money, time, and effort is wasted in locating the proper place. Consequently it affects the country's economy also.

So what is the alternative? We can use Geo code. That is geographical coordinates of latitude and longitude. But it is difficult to remember and convey. People have come out with some new ideas. The earth surface is divided into squares of side 3 m (10 feet). We get 57 trillion square plots. Each 10 feet square is addressed with a unique 3 word phrase. 40000 words are enough to address all the plots in the earth surface. Let us see how?

For example, 2 words are enough to address 8 plots or places. Let the 2 words be give and take

ADDRESSES

1. give.give.give
2. take . take.take
3. give.give.take
4. give.take.give
5. take.give.give
6.take.take.give
7. take.give.take
8.give.take.take

Cube root of 8 is 2
similarly, cube root of 57 trillion is 40000. So 40000 words are enough to address all the 100 square feet (10*10) plots in the world.

The 3 word address of Tajmahal in India is "according . bloom.broads."

Now install what 3 word(w3w) app. in your smart phone and find the 3 word address for your home or any location.

It is a open source product. But remember the 3 word address change for every 10 feet. So you may get multiple addresses for your home. So we have to still innovate and find a good address system.

A accurate address will save lives in the case of accident, fire and emergencies. A good address system with GPS mobile will make our life easier.

Now is the time to address this problem.

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
