How does Indian PIN code system work?

India Map with PIN codes Postal Index Number (PIN) code is a six digit number which was introduced on August 15, 1972 and appears in almost all postal articles. Though PIN code has not received much respect in the recent times with more private courier companies coming into picture and stressing more on providing phone number than PIN code, it is indeed one of the most important piece of information which ensures your package reaches the correct location. So it may not be wrong to say that the PIN code is as important to a letter as is a steering wheel to a car!!!
How does a PIN code work?
The PIN code system works on a coding system wherein each number represents a particular place and the combination of these letters determine the location to which the package is to be delivered.
The entire country has been divided into nine zones including eight regional zones and one functional zone, which is provided below:
States Covered
Delhi, Haryana, Punjab, Himachal Pradesh, Jammu & Kashmir
Northern Uttar Pradesh and Uttaranchal
Western Rajasthan and Gujarat
Western Chattisgarh, Maharashtra and Madhya Pradesh
Southern Andhra Pradesh and Karnataka
Southern Kerala and Tamil Nadu
Eastern West Bengal, Orissa and North Eastern
Eastern Bihar & Jharkhand

Army Post office(APO) and Field Post office(FPO)

The first digit indicates one of these zones / region.
First 2/3 Digits of PIN
12 and 13
14 to 16
Himachal Pradesh
18 to 19
Jammu & Kashmir
20 to 28
Uttar Pradesh
30 to 34
36 to 39
40 to 44
45 to 48
Madhya Pradesh
50 to 53
Andhra Pradesh
56 to 59
60 to 64
Tamil Nadu
67 to 69
Lakshadweep (Islands)
70 to 74
West Bengal
Andaman & Nicobar Islands
75 to 77
North Eastern
793, 794, 783123
80 to 85

The second digit indicates the sub-region, and the third digit indicates the sorting district within the region.

The next three digits will indicate the particular post office where the letter is to be delivered.
The first 3 digits together will indicate the sorting or revenue district where the letter is to be basically routed. The last 3 digits refer to the actual post office where the article is to be finally delivered.
The PIN code for the Press Information Bureau in Madurai is 625 020. Here the first digit 6 again stands for the PIN zone – Tamil Nadu, Pondicherry and Kerala. The next two digits – 25 – represent the District of Madurai, while the two final digits -20 - together represents the post office of Gandhi nagar, the delivery post office for PIB, Madurai!
Here it is also important to note that the number given to the Gandhi nagar post office in the city of Madurai in Tamil Nadu is unique. No other post office in India will have this number. A check with the post PIN code directory will reveal that the delivery post offices in Mathura – the holy city in Uttar Pradesh (UP) – with which the temple city of Madurai is likely to be confused has a completely different PIN code – 281 001. Two stands for the PIN zone consisting of UP and Uttarkhand; 81 represents the district of Mathura while 001 stands fro Mathura Head Post office.

Rajinikanth’s theory of Light

Rajinikanth's theory of light
Practical demonstration of the theory
Theory of light specifically referring to the corpuscular theory of light, set forward by Sir Isaac Newton, states that light is made up of small discrete particles called corpuscles (little particles) which travel in straight line with a finite velocity and possess kinetic energy. 

Though Newton's theory remained in force for more than 100 years, if failed to answer the most important question which has troubled humankind for centuries altogether. The unanswered question related to harnessing the power of ordinary light from artificial for lighting man made items like a cigar.

This illusive question remained unanswered for centuries. Ultimately, Padma Bhushan Shri Rajinikanth ji answered this question in the year 2002. He explained the entire concept in a 214 page book titled, Rajinikanth’s theory of Physics, Volume III. For the benefit of our readers, we have provided the abstract provided by him.
Throw a beam of your torch light on a mirror with a refractive index 100 at an angle of 17.63 degrees. The reflected beam hits the ceiling and then further hits the wall before striking the cigar. The reflected light due to high air friction and friction at the wall gets converted into heat which in turn gets converted into fire in 0.001256 micro seconds. The resulting fire lights the cigar.”
We hope that he will keep illuminating our lives with such ground breaking theories in the future.

Google tests new ‘Sitelinks’ layout and design

It is a known fact that Google iterates its search results from time to time to try new things. A few months before changing to the new search layout (currently applied), Google changed its layout and design.

Original Sitelinks as seen for cnet:

Google search results (normally)

New SItelinks as seen for sinapse blog:

Google search results (new format)

The new search layout provides ‘Sitelinks’ with are now underlined, show the link and a very small snippet. The new sitelinks format is descriptive and helps to understand the content of each sitelink. However, it makes the sitelinks occupy a lot of screen space.

Further, sitelinks generally show up only when the search is directly matching with a site. In case of specific searches like that of ‘sinapse blog’ would be helpful.

Update – A day later the new trial format seems to have been changed back to original one: see below image
